篇1：如何拿下雅思阅读长难句
如何拿下雅思阅读长难句
雅思阅读长难句解析：
英语的基本句式结构其实很简单：主谓宾和主系表。主谓宾是“谁-做-什么”，例如：比如“羊吃草”;“洁白可爱的小绵羊蹦蹦跳跳欢快活泼地在一望无垠的广阔草原上幸福愉快地吃着鲜嫩碧绿的青草”一样也是主谓宾，只不过多了一些修饰的词，句子的核心意思还是“羊吃草”。主系表是“谁-是-什么”，同主谓宾一样。在阅读中我们要很快的找出核心句子，雅思阅读练习, 不出国考雅思有用吗不用每句话的意思都懂，但要知道这句话要表达的核心意思，即找到主谓宾或主系表的主体。
针对这两种句式结构抓主干，即把复杂的长难句转化成简单的句子。
主谓宾结构：寻找谓语动词
主系表结构：寻找系动词
也就是说，无论哪种句式，我们都要在心里默念寻找动词这个原则，以模糊匹配的方式来对应最有意义的那个动词，进而确认动词之前的主语和动词之后的宾语或表语。
雅思阅读练习雅思阅读考试，一个句子之所以能够拉长，除了在一个简单句中加上许多修饰成分之外，还有可能是长出了枝干—也就是加了从句，或者是由连词和平衡结构把若干简单句合并在了一起。雅思长难句最频繁出现的情况包括如下几种：
定语从句：that, which(介词+which), who,…
状语从句：v+ing
寻找平衡结构：三大连词 and/or/but，
not only…but also…
not…but…
no more/longer/less …than
as…as
not so …as… . . .
还有一种特殊主系表值得单独说一说：
There be句型：寻找中心词
雅思阅读练习这个句型之所以特殊，是因为系动词和表语都已经以倒装的形式给出来了，欠缺的只是一个主语中心词而已，因此我们看到了there be开头的句子，一定先集中精力寻找到那个中心点。此外，这个句子是一些同学在雅思作文考场上易犯错误的地方。在时间紧迫的压力下，可能会有同学不自觉地受到了中文思维的影响，写出诸如“There are many people do something.”此类的句子，如果在模拟考试的时候发现自己曾经犯过这类笔误，建议大家在考场上给自己留出1、2分钟的检查时间来。雅思阅读练习, 不出国考雅思有用吗查方法也很简单，把there be两个词遮住，如果剩下的部分还能读出一个完整的句子来，则原本的句子必定是有问题的，可以迅速把there be这两个词擦掉。
除了be动词外，还有一些there be形式的变体：
There come/comes/came
There appear/appears/appeared
There emerge/emerges/emerged
There may/might be
There can/could be
There happen to be
There used to be
There is/are going to be
其中后两个句子中说到的情况一定是不存于当下的，在判断题(TRUE/FALSE/NOT GIVEN)中容易被揪出来做文章，出题思路是细节不一致的类型，答案多为FALSE。
雅思阅读水平提升的三个关键点
虽然很多同学针对于雅思阅读都进行相关技巧训练， 但是要想切实的提高雅思阅读水平，还是需要注意这一些细节的，分享给大家，希望对大家有所帮助，文中观点仅供参考。
提高雅思阅读水平一，Skimming and Scanning
由于雅思考试中有大量的填空题、问答题以及多项选择题，因此能否做好此类题目是阅读考试能否取得理想成绩的关键所在。
雅思阅读测试的一大特色是同义词(synonyms)和释义表达(paraphrasing)。因此，考生在做此类题目的过程中，要首先判断哪个是关键词(keywords)，以及它的同义词，然后根据该词迅速在文章中寻找，准确定位(locating the expected information)，最后根据要求填空。
众所周知，雅思阅读一般取材于报刊、杂志等，因此平时应大量阅读英文报刊，像《英国镜报》、《卫报》等，以了解英文报刊文章的表达习惯和常用表达式。
提高雅思阅读水平二，good reading habits
很多中国考生在平时训练阅读时没有养成良好的阅读习惯，在阅读过程中，往往一遇到生词就想查文曲星、字典之类的辅助工具。由于雅思阅读考试的取材都来自原版报刊杂志，文章中必然出现不少考生没有见过或者很少碰到的生词，尤其是学术类阅读第三篇文章的词汇量往往很大，这时良好的阅读习惯就成了我们能否获取理想成绩的关键。词汇分：名词(用作主语或宾语)，动词(用作谓语)，形容词和副词(用作定语或状语)，我们发现，在相当多的情况下，形容词和副词是最难以记忆的，也就是我们不常熟悉的。但是它们一般不太会影响我们的句子理解能力。
提高雅思阅读水平三，long sentence understanding
很多考生过分注重考试技巧，没有注重阅读理解能力的提高，在考试中往往面对一堆长长的句子，不知所措，稀里糊涂。
我们知道，英文句子由主语、谓语和宾语构成了基本句式，形成了“核心意群”(core meaning)，它们的成分，如定语或者定语从句，状语等等在句子中仅仅起到对“核心意群”的修饰或者补充作用而已，不会对它产生很大的影响。

篇2：如何攻克雅思阅读长难句
In the earliest stages of man's development he had no more need of money than animals have.He was content with very simple forms of shelter,made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him.As he became more civilized,however,he began to want better shelter,more efficient tools and weapons,and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands.For these things he had to turn to the skilled people such as smiths,leather workers or carpenters.It was then that the question of payment arose.
At first he got what he wanted by a simple process of exchange.The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough.But as more and more goods which had no fixed exchange value came on the market,exchange became too complicated to be satisfactory.Another problem arose when those who made things wanted to get stocks of wood or leather,or iron,but had nothing to offer in exchange until their finished goods were ready.
Thus the difficulties of exchange led by degrees to the invention of money.In some countries easily handled things like seeds or shells were given a certain value and the farmer,instead of paying the smith for a new axe by giving him some meat or grain,gave him so many shells.If the smith had any shells left when he had bought his food,he could get stocks of the raw materials of his trade.In some countries quite large things such as cows or camels or even big flat stones were used for trade.Later,pieces of metal,bearing values according to the rarity of the metal and the size of the pieces,or coins were used.Money as we know it had arrived.
1.Exchange of goods became difficult because _________.
A man became more civilized
B smiths began to look after land or cattle in their spare time
C more and more goods which had no fixed exchange values came to the marker
D farmers hadn't enough grain or meat to provide for skilled workers
2.Money was not used until _______.
A paper was invented
B people practiced a simple process of exchange
C nothing could be offered in exchange
D the exchange of one thing for another became too complicated
3.The best title for this passage is _____.
A What is money
B What are money's functions.
C The importance of money
D The beginning of money
注释：
1.stage阶段;时期at an early stage in our history
在我们的历史早期
(前面与the连用)演员生涯;剧院工作;戏剧工作行程，旅程
to travel by easy stages从容旅行
2.content n.内容，容量，目录，满足adj.满足的，满意的，愿意vt.使满足
We should never content ourselves with a little book knowledge only.我们切不可满足于仅仅有一点点书本知识。
3.shelter n.掩蔽处，身避处，掩蔽，保护，庇护所，掩体v.掩蔽，躲避
He stood in the shelter at the bus stop.他站在公共汽车站的候车亭里。
4.smith n.铁匠，金属品工匠
leather n.皮革，皮革制品
carpenter n.木匠
5.axe or plough斧或犁
6 complicate使复杂化，使错综加重(疾病)使混乱，难做、难懂;使恶化

Don't complicate life for me!不要为我把生活搞复杂了!
答案：1 C 2 D 3 D
篇3：突破雅思阅读长难句
【阅读高分技巧】化繁为简 突破雅思阅读长难句
要最有效率地善用时间，拿到自己满意的分数，我们可以从两个方面入手：一方面是技巧，知道怎样依据题目给出的指向，去文章的什么地方寻找答案;另一方面则是硬碰硬的速读能力，很快地扫描全文，然后挑拣出有用信息所在的句子。
从长远角度来看，后者对于各位鸭鸭们更为重要，毕竟考到了满意的分数只是开始而非结束，去了自己心仪的学校以后还是要接受铺天盖地的英语材料轰炸。特别是对于准备时间比较充分因此相对从容的同学，不如就从雅思备考的这个阶段开始准备吧。
英语的句式结构其实很简单：主谓宾和主系表。主谓宾是“谁—干—什么”，比如“羊吃草”。“洁白可爱的小绵羊蹦蹦跳跳欢快活泼地在一望无垠的广阔草原上幸福愉快地吃着鲜嫩碧绿的青草”一样也是主谓宾，只不过修饰成分多了些、显得唐僧了些而已。
主系表是“谁—是—什么”，复杂版本参考同上。要很快地理解这样的句子，我们就要学会迅速地抓出句子的主干—也就是“羊吃草”的部分，至于其它的修饰部分可以先不过大脑。如果主干显示本句子中包含了解题信息的话，此时再去细细查看题目要问的细节信息也不迟。
这样的抓主干技巧一旦熟练，要有充分的时间通读三篇文章、保证不遗漏任何信息地做题，也不是什么不可完成的任务了。特别是对于那些原本语言功底就不错、希望能以阅读这一项的得分再提高一下总成绩的同学来说，这是真正的终极技巧，要达到保8望9也是很有希望的。
针对两种句式结构的抓主干方法，简单说来如下：
化繁为简看懂句子
主谓宾结构：寻找谓语动词
主系表结构：寻找系动词
也就是说，无论哪种句式，我们都要在心里默念寻找动词这个原则，以模糊匹配的方式来对应最有意义的那个动词，进而确认动词之前的主语和动词之后的宾语或表语。
一个句子之所以能够拉长，除了在一个简单句中加上许多修饰成分之外，还有可能是长出了枝干—也就是加了从句，或者是由连词和平衡结构把若干简单句合并在了一起。雅思长难句最频繁出现的情况包括如下几种：
定语从句：that, which(介词+which), who,…
状语从句：v+ing
寻找平衡结构：三大连词 and/or/but，
not only…but also…
not…but…
no more/longer/less …than
as…as
not so …as… . . .
还有一种特殊主系表值得单独说一说：

雅思阅读模拟练习及答案
Patients and doctors alike have long believed in the healing (治疗) power of humor. It is claimed that humor not only affects patients’ moods, but can actually help them recover faster.
Several studies seem to support this. Patients in better spirits are known to have higher immune cell counts. Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies.
Despite all this, many researchers are not convinced. They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter. They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first.
Humor in times of stress, however, clearly makes us feel better. On one level, it takes our minds off our troubles and relaxes us. On another, it releases powerful endorphins, a chemical produced by your body that reduces pain.
There are cases where the appreciation of a good joke is indeed directly related to a person’s health. It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe (额叶).
Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list. Subjects with normal brains usually chose endings that were based on a relatively complex synthesis (综合) of ideas. Subjects with specifically located brain damage, however, responded only to slapstick (闹剧) endings, which did not depend on a particular context. When pressed, the brain-damaged subjects saw the logic in the correct endings. They simply did not find them funny.
Of course, humor is largely an individual matter. Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain. However, you might suggest that he lighten up—for the health of it.
58. We can infer from the passage that ________.
A. all researchers have agreed on the healing power of humor
B. people seldom accuse their friends of not understanding jokes
C. the author holds a positive attitude to the healing power of humor
D. reading comics will surely become a popular way of treating diseases
59. Which of the following statements is NOT true?
A. Many researchers are not convinced of the healing power of humor.
B. Patients in bad moods are known to have higher immune cell counts.
C. Optimism in general does seem to be related to better health.
D. People should try their best to cheer up for their good health.
60. Scientists had some people read jokes and asked them to choose the funniest endings from a list to confirm that ________.
A. the brain-damaged people are different from those with normal brains
B. a person with a normal brain usually responds to slapstick endings
C. a person suffering certain brain damage doesn’t appreciate a good joke
D. humor takes our minds off our troubles by releasing powerful endorphins
61. Which would be the best title for the passage?
A. Which comes first, humor or health? B. Humor can cure different illnesses
C. People need humor in times of stress D. Humor contributes to good health

篇4：如何攻克雅思阅读长难句
Next Year Marks the EU's 50th Anniversary of the Treaty
A.After a period of introversion and stunned self-disbelief,continental European governments will recover their enthusiasm for pan-European institution-building in .Whether the European public will welcome a return to what voters in two countries had rejected so short a time before is another matter.
B.There are several reasons for Europe's recovering self-confidence.For years European economies had been lagging dismally behind America(to say nothing of Asia),but in the large continental economies had one of their best years for a decade,briefly outstripping America in terms of growth.Since politics often reacts to economic change with a lag,2006's improvement in economic growth will have its impact in 2007,though the recovery may be ebbing by then.
C.The coming year also marks a particular point in a political cycle so regular that it almost seems to amount to a natural law.Every four or five years,European countries take a large stride towards further integration by signing a new treaty:the Maastricht treaty in 1992,the Treaty of Amsterdam in ,the Treaty of Nice in .And in they were supposed to ratify a European constitution,laying the ground for yet more integration—until the calm rhythm was rudely shattered by French and Dutch voters.But the political impetus to sign something every four or five years has only been interrupted,not immobilised,by this setback.
D.In 2007 the European Union marks the 50th anniversary of another treaty—the Treaty of Rome,its founding charter.Government leaders have already agreed to celebrate it ceremoniously,restating their commitment to“ever closer union”and the basic ideals of European unity.By itself,and in normal circumstances,the EU's 50th-birthday greeting to itself would be fairly meaningless,a routine expression of European good fellowship.But it does not take a Machiavelli to spot that once governments have signed the declaration(and it seems unlikely anyone would be so uncollegiate as to veto it)they will already be halfway towards committing themselves to a new treaty.All that will be necessary will be to incorporate the 50th-anniversary declaration into a new treaty containing a number of institutional and other reforms extracted from the failed attempt at constitution-building and—hey presto—a new quasi-constitution will be ready.
E.According to the German government—which holds the EU's agenda-setting presidency during the first half of 2007—there will be a new draft of a slimmed-down constitution ready by the middle of the year,perhaps to put to voters,perhaps not.There would then be a couple of years in which it will be discussed,approved by parliaments and,perhaps,put to voters if that is deemed unavoidable.Then,according to bureaucratic planners in Brussels and Berlin,blithely ignoring the possibility of public rejection,the whole thing will be signed,sealed and a new constitution delivered in -10.Europe will be nicely back on schedule.Its four-to-five-year cycle of integration will have missed only one beat.
F.The resurrection of the European constitution will be made more likely in 2007 because of what is happening in national capitals.The European Union is not really an autonomous organisation.If it functions,it is because the leaders of the big continental countries want it to,reckoning that an active European policy will help them get done what they want to do in their own countries.
G.That did not happen in 2005-06.Defensive,cynical and self-destructive,the leaders of the three largest euro-zone countries—France,Italy and Germany—were stumbling towards their unlamented ends.They saw no reason to pursue any sort of European policy and the EU,as a result,barely functioned.But by the middle of 2007 all three will have gone,and this fact alone will transform the European political landscape.
H.The upshot is that the politics of the three large continental countries,bureaucraticmomentum and the economics of recovery will all be aligned to give a push towards integration in 2007.That does not mean the momentum will be irresistible or even popular.The British government,for one,will almost certainly not want to go with the flow,beginning yet another chapter in the long history of confrontation between Britain and the rest of Europe.More important,the voters will want a say.They rejected the constitution in 2005.It would be foolish to assume they will accept it after 2007 just as a result of an artful bit of tinkering.
Questions 1-6 Do the following statemets reflect the claims of the writer in Reading Passage 1?
Write your answer in Boxes 1-6 on your answer sheet.
TRUE if the statemenht reflets the claims of the writer
FALSE if the statement contradicts the claims of the writer
NOT GIVEN if it is possbile to say what the writer thinks about this
1.After years'introspection and mistrust,continental European governments will resurrect their enthusiasm for more integration in 2007.
2.The European consitution was officially approved in 2005 in spite of the oppositon of French and Dutch voters.
3.The Treaty of Rome,which is considered as the fundamental charter of the European Union,was signed in 1957.
4.It is very unlikely that European countries will sign the declaration at the 50th anniversary of the Treaty of Rome.
5.French government will hold the EU's presidency and lay down the agenda during the first half of .
6.For a long time in hisotry,there has been confrontation between Britain and the rest of European countries.
篇5：雅思阅读长难句如何攻克
雅思阅读长难句如何攻克
雅思阅读长难句指的是一般的简单句由主、谓、宾、定、状、补等这些基本成分构成，事实上长难句即是在短句后加上从句，让句子看上去结构更复杂，又长又难以理解。
攻克雅思考试阅读长难句的步骤主要有四点，即：
1)了解基本句型
英语基本句型大致上包含有5种，比如主谓，主谓宾，主谓表，主谓双宾(间接宾语，直接宾语)以及主谓宾+宾语补足语。这些句型表面看上去简单，但只要综合在一起来，是会变成比较复杂的句子，让考生很头疼的长难句，比如由that、which等这些引导的定语从句，状语从句，there be句型等，那么分析与理解句子来不容易了。所以考生要先把基本句型搞清楚之后才能在此基础之上攻克长难句。
2)找到主干
当把基本句型之理解以后，想要突破长难句，考生要能够找到长难句中的主干，把其他修饰部分的干扰都排除。主干指的是长难句的核心信息，也就是主、谓、宾三个成分。一般来说，主语一般是会通过有的关键的单词，关键的信息表达出来。在找谓语动词时，考生要了解的是，并不是全部主语后面的动词即为谓语，考生一定要分清。另外，如果主语后面出现逗号时，一般需要找到第二个逗号，之后的动词则是谓语动词。找到主谓就算成功一大半了，宾语部分相对好找一些。
3)分析主干部分的修饰语
在长难句中，谓语动词把时态除外变化不是很大。但是主语与宾语会有所变化，像主语与宾语一般会在各种从句，介词短语，形容词等中存在，考生若可以从这些结构里把哪部分是主语，哪部分是宾语分析出来。
4)句子翻译
在明确句子主干以及句子的成分之后，考生需要把后一个步骤掌握，即翻译。当考生翻译句子时，需要留意中英翻译间的区别与语序问题。在平时练习时留心这些细节，方能有所改进。
雅思阅读材料：美学者发明可视眼镜
High-tech glasses developed at Washington University School of Medicine in St. Louis may help surgeons visualize cancer cells, which glow blue when viewed through the eyewear.
The wearable technology, so new it's yet unnamed, was used during surgery for the first time today at Alvin J. Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine.
Cancer cells are notoriously difficult to see, even under high-powered magnification. The glasses are designed to make it easier for surgeons to distinguish cancer cells from healthy cells, helping to ensure that no stray tumor cells are left behind during surgery.
“We're in the early stages of this technology, and more development and testing will be done, but we're certainly encouraged by the potential benefits to patients,” said breast surgeon Julie Margenthaler, MD, an associate professor of surgery at Washington University, who performed today's operation. “Imagine what it would mean if these glasses eliminated the need for follow-up surgery and the associated pain, inconvenience and anxiety.”
Current standard of care requires surgeons to remove the tumor and some neighboring tissue that may or may not include cancer cells. The samples are sent to a pathology lab and viewed under a microscope. If cancer cells are found in neighboring tissue, a second surgery often is recommended to remove additional tissue that also is checked for the presence of cancer.
The glasses could reduce the need for additional surgical procedures and subsequent stress on patients, as well as time and expense.
Margenthaler said about 20 to 25 percent of breast cancer patients who have lumps removed require a second surgery because current technology doesn't adequately show the extent of the disease during the first operation.
“Our hope is that this new technology will reduce or ideally eliminate the need for a second surgery,” she said.
The technology, developed by a team led by Samuel Achilefu, PhD, professor of radiology and biomedical engineering at Washington University, incorporates custom video technology, a head-mounted display and a targeted molecular agent that attaches to cancer cells, making them glow when viewed with the glasses.
In a study published in the Journal of Biomedical Optics, researchers noted that tumors as small as 1 mm in diameter (the thickness of about 10 sheets of paper) could be detected.
Ryan Fields, MD, a Washington University assistant professor of surgery and Siteman surgeon, plans to wear the glasses later this month when he operates to remove a melanoma from a patient. He said he welcomes the new technology, which theoretically could be used to visualize any type of cancer.
“A limitation of surgery is that it's not always clear to the naked eye the distinction between normal tissue and cancerous tissue,” Fields said. “With the glasses developed by Dr. Achilefu, we can better identify the tissue that must be removed.”
In pilot studies conducted on lab mice, the researchers utilized indocyanine green, a commonly used contrast agent approved by the Food and Drug Administration. When the agent is injected into the tumor, the cancerous cells glow when viewed with the glasses and a special light.
Achilefu, who also is co-leader of the Oncologic Imaging Program at Siteman Cancer Center and professor of biochemistry and molecular biophysics, is seeking FDA approval for a different molecular agent he's helping to develop for use with the glasses. This agent specifically targets and stays longer in cancer cells.
“This technology has great potential for patients and health-care professionals,” Achilefu said. “Our goal is to make sure no cancer is left behind.”
Dr. Achilefu has worked with Washington University's Office of Technology Management and has a patent pending for the technology.
The research is funded by the National Cancer Institute (R01CA171651) at the National Institutes of Health (NIH).
透过一副特制的高科技眼镜，医生小心切除闪着蓝光的癌变组织……当地时间2月10日，一台特殊的外科手术在美国密苏里州圣路易斯市一家医院里进行，借助这项刚刚问世的可视技术，原本几不可见的癌细胞变得无所遁形。
据美国媒体报道，这副能够“看见”癌细胞的眼镜由华盛顿大学(W U)放射学和生物医学工程学教授塞缪尔?阿基里弗教授领队研发成功，在理想状态下，它可以帮助外科医生在手术时一次性彻底切除所有癌变组织。
众所周知，即使置于高性能的显微镜下，癌细胞也难以被发现。但有了这副眼镜之后，医生能够轻松区分健康细胞和癌细胞，从而确保首次手术时不会遗漏任何癌变组织，进行二次切除手术以“查缺补漏”的可能性也由此大大降低。
据介绍，使用时，需要先把一种特定的分子药剂涂抹在肿瘤及其周边组织上，这种药剂会附着于癌细胞、令其发出肉眼不可见的光芒，然后，主刀医生戴上一个形似眼镜的头盔式显示器，通过自定义视频技术，即可看清癌细胞分布于何处。
“目前，我们尚处于研究初期，未来会进行更多的改进和测试工作。”乳腺外科医生朱莉?马格塔勒是10日进行手术的主刀大夫，同时也是个在实际操作中使用癌细胞可视眼镜的人，“一想到这项新技术将令病患获益良多，我们就干劲十足。”
依据现在的医护流程，外科医生手术时需要切除肿瘤及其附近组织，而这些组织中可能存在、也可能不存在癌细胞。随后，切除下的组织标本被送往病理实验室接受检验，如果在其中发现癌细胞，则需进行第二次甚至多次手术，直至癌变组织被完全切除。
据马格塔勒介绍，依靠现有的技术，无法准备判定癌变组织的全部范围，所以大约20%至25%的乳腺癌患者接受首次手术切除肿瘤后，还需经受第二次手术。
“借助这种癌细胞可视眼镜，可以在首次手术时一次性切除所有癌变组织。这意味着，没有必要再进行后续手术，病人也无需承担随之而来的病痛和手术费用。”马格塔勒希望，这项新技术能够降低、甚至完全消除二次手术。

篇6：雅思阅读长难句翻译练习
01.That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted.
那种性别比例能在最大程度上增加一个个体所能拥有的后代数量，并因此能在最大程度上增加所传递到后代身上去的基因复制品的数量。
02. (This is) A desire to throw over reality a light that never was might give away abruptly to the desire on the part of what we might consider a novelist-scientist to record exactly and concretely the structure and texture of a flower .
(这是一种)照亮现实的欲望，此欲望从来就不会唐突的取代后面的那种欲望，后者是我们可以将其部分的理解为一个兼任小说加和科学家的人想要去准确并具体的记录下一朵花的结构和文理的那种意义上的欲望。
03. Hardy's weakness derived from his apparent inability to control the comings and goings of these divergent impulses and from his unwillingness to cultivate and sustain the energetic and risky ones.
哈代的缺陷一方面缘起于他的某种明显的无能，无法控制好那结不尽相同的创作冲动的穿梭往来;另一方面缘起于他不愿意去培养和维持那些富于生机活力和风险性强的创作冲动。
04. Virginia Woolf's provocative statement about her intentions in writing Mrs. Dalloway has regularly been ignored by the critics，since it highlights an aspect of her literary interests very different from the traditional picture of the “poetic” novelist concerned with examining states of reverie and vision and with following the intricate pathways of individual consciousness.
弗吉尼亚.伍尔夫(Virginia Woolf)在创作《黛洛维夫人》(Mrs. Dalloway)时有关其创作意图的这番发人深思的陈述，迄今为止一贯为文学评论家们所忽略，因为它突出反映了她诸多文学兴趣中某一方面，而这一方面则与人们对“诗性”小说家(poetic novelist)所形成的传统见解大相径庭。所谓的“诗性”小说家，所关注的是审视想入非非和白日梦幻的诸般状态，并致力于追寻个体意识的通幽曲径。
05. As she put it in The Common Reader , “It is safe to say that not a single law has been framed or one stone set upon another because of anything Chaucer said or wrote ; and yet , as we read him , we are absorbing morality at every pore .”
就像她在《致普通读者》一书中所表达的那样，“尽管可以毫无疑问的说，没有任何法律被指定出来，也没有任何高楼大厦被建立起来是因为乔叟说了什么或者写了什么;然而，当我们读它的书的时候，我们身上每一个毛孔都充满了道德”
06. With the conclusion of a burst activity , the lactic acid level is high in the body fluids , leaving the large animal vulnerable to attack until the acid is reconverted , via oxidative metabolism , by the liver into glucose , which is then sent (in part )back to the muscles for glycogen resynthesis .
随着爆发出来的运动的结束，再体液中乳酸含量会变得很高，使得大型动物处于容易受到攻击的状态，直到乳酸通过有氧新陈代谢，被肝脏转化成(convert into)葡萄糖，而葡萄糖接下来又会(部分)传送回肌肉中重新合成糖原 .
07. Although Gutman admits that forced separation by sale was frequent，he shows that the slaves' preference，revealed most clearly on plantations where sale was infrequent，was very much for stable monogamy.
虽然古特曼承认，由于奴隶买卖而造成的被迫离散甚为频繁，但他还是证明，奴隶的偏爱——在那些奴隶买卖并不频繁的种植园上被最为显著地揭示出来——在很大程度上侧重于稳定的一夫一妻制(monogamy)。
08. Gutman argues convincingly that the stability of the Black family encouraged the transmission of-and so was crucial in sustaining-the Black heritage of folklore,music,and religious expression from one generation to another，a heritage that slaves were continually fashioning out of their African and American experiences.
古特曼人令人信服地论辨道，黑人家庭的稳定有助于包括民间传说、音乐、及宗教表达在内的黑人文化遗产一代一代传递下去，因而在维持文化遗产方面也起着至关重要的作用，而对于这种文化遗产，黑奴们不断地从其非洲和美洲的经历中予以丰富发展。
09. This preference for exogamy，Gutman suggests,may have derived from West African rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin.
古特曼表示，这种对于外部通婚的偏爱很有可能缘起于西部非洲制约着婚姻的规定，尽管这些规定在一个和另一个部落群体之间不尽相同，但都涉及到某种对近亲联姻(union with close kin)的禁止。
10. His thesis works relatively well when applied to discrimination against Blacks in the United States，but his definition of racial prejudice as “racially-based negative prejudgments against a group generally accepted as a race in any given region of ethnic competition，” can be interpreted as also including hostility toward such ethnic groups as the Chinese in California and the Jews in medieval Europe.
该社会学家的命题当被应用于针对美国黑人的歧视时，相对而言尚能适用，但他对种族偏见所下的定义——即“以种族为基础的、针对某个群体的消级的先入之见，而该群体在任何特定的种族竞争地区则被普遍认作一种族”——可被理解成同样也襄括了针对加利福尼亚州的中国人以及中世纪的犹太人这样一些种族群体的敌视态度。
篇7：雅思阅读长难句翻译练习
51. The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most geologists contend，is the upper mantle.
对于地幔分层论点来说，最好的证据乃这样一个确认的事实，即在那些海洋岛屿——这些岛屿据信是源于由下层地幔升上来的地幔柱状溶岩流(mantle plume)——上发现的火山岩石，是由与海洋中部山脊系统的物质根本不同的物质构成的，而这一海洋中部山脊系统的成因，大多数地质学家论辩道，为上部地幔。
52. Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in “incompatible elements” (elements tending toward liquid rather than solid state)percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids' pathways.
但是，某些地质学家，以对地幔捕虏岩体(xenolith)所作的观察为依据，指出地幔并非是分层排列的，相反，地幔的异质性是由那些富含“不相容成分”的流质构成的，这些成分趋向于流体而非固体的状态，自下而上渗透扩散，并依照这些流质流向的任意性，不规则地将上部地幔的某些部分予以改变。
53. Fallois proposed that Proust had tried to begin a novel in 1908, abandoned it for what was to be a long demonstration of Saint-Beuve's blindness to the real nature of great writing , found the essay giving rise to personal memories and fictional developments ,and allowed these to take over it a steadily developing novel.
F认为，P在19试图开始写一部小说，又为了写一部批判S-B的 伟大作品的真正本质的视而不见的长篇的证明而放弃了这部小说，其后又发现这一论文又勾起了其个人记忆及小说情节的萌生，使得后者取而代之形成了一部稳定展开的小说。
54. The very richness and complexity of the meaningful relationships that kept presenting and rearranging themselves on all levels，from abstract intelligence to profound dreamy feelings， made it difficult for Proust to set them out coherently.
各种有意义的联系在所有的层次上，自抽象的理性至深刻的梦幻般的情感，层出不穷并不断重新组合排列;正是这些有意义的联系的丰富性和复杂性，致使普鲁斯特难于将它们错落有致地安排好。
55. But those of who hoped, with Kolb, that Kolb's newly published complete edition of Proust's correspondence for 1909 would document the process in greater detail are disappointed.
但是我们当中的那些希望(也算上K本人)K新出版的P19书信的全集能够更加详细的记录下这一过程的人都大失所望。
56. Now we must also examine the culture as we Mexican Americans have experienced it , passing from a sovereign people to compatriots with newly arriving settlers to , finally ，a conquered people - a charter minority on our own land.
现在我们必须也按照我们墨西哥裔的美国人的经历来审视这个文化，我们的经历是从一个主权的民族变成了新来的定居者的同胞，在最终沦落成为一个被征服的民族——在我们自己的土地上的契约的少数民族。
57. It is possible to make specific complementary DNA's (cDNA's)that can serve as molecular probes to seek out the messenger RNA's (mRNA's) of the peptide hormones. If brain cells are making the hormones，the cells will contain these Mrna'S. If the products the brain cells make resemble the hormones but are not identical to them，then the cDNA's should still bind to these mRNA's，but should not bind as tightly as they would to mRNA's for the true hormones.
科学家可以制造出特异的(specific)互补DNA's(cDNA's)，以此作为分子探子(molecular probe)，探觅出肽激素的信使RNA's(mRNA's)。如果大脑正在制造着肽激素，则细胞就会含有这些信使RNA's.假若细胞所制造的产品类似于肽激素但并非与这些肽激素全然相同，那么，互补cDNA's应仍然和这些信使mDNA's粘结的程度。含有这些mRNA's的脑细胞然后就可以被分离开来，研究者可对其信使RNA's进行解码，以确定它们的蛋白质产品究竟是什么，并确定这些蛋白质产品在何种程度上类似于真正的肽激素。
58. The molecular approach to detecting peptide hormones using cDNA probes should also be much faster than the immunological method because it can take years of tedious purifications to isolate peptide hormones and then develop antiserums to them. 采用cDNA探子来测定肽激素的这一分子生物学方法同时也应该比免疫学的方法速度来得快，因为对于免疫的方法来说，需耗费好几年枯燥的提纯进程，方能将肽素分离了出来，然后再培养出针对它们的抗血清。
59. Nevertheless, researchers of the Pleistocene epoch have developed all sorts of more or less fanciful model schemes of how they would have arranged the Ice Age had they been in charge of events.
然而，研究P时代的研究者发展除了各种各样的或多或少有些奇怪思想的模型系统，用来显示如果由他们来决定地质事件的话他们将会如何安排冰川纪。
60. This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods，rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits.
这一序列演替(succession)所依据的，主要是一系列与冰川期和间冰期并不直接相关的地质沉积物和地质事件，而不是依据更为普遍的现代方法，去研究间冰层(interglacial bed)中所发现的生物残留物，而这些间冰层本身又在冰川沉积物发生间层化(interstatified)。
篇8：雅思阅读长难句翻译练习
21. As my own studies have advanced，I have been increasingly impressed with the functional similarities between insect and vertebrate societies and less so with the structural differences that seem，at first glance，to constitute such an immense gulf between them.
随着我的研究不断深入，我对昆虫和脊椎动物群落之间的功能类似性印象愈来愈深刻，而对结构上的差异印象愈发淡漠，虽然这些结构上的差异初看上去似乎构成了二者间一条无法愈越的鸿沟。
22. Although fiction assuredly springs from political circumstances，its authors react to those circumstances in ways other than ideological，and talking about novels and stories primarily as instruments of ideology circumvents much of the fictional enterprise.
虽然小说无疑起源于政治情状，但其作者则是以非意识形态的方式对这些政治情状作出反应的，而将小说和故事主要地当作意识形态的工具来探讨，会在相当程度上阻碍小说事业。
23. Is this a defect，or are the authors working out of，or trying to forge，a different kind of aesthetic?
这究竟是一种缺陷呢，还是这些作者想要按照一种与众不同的美学体系进行创作，抑或是在试图创立一种与众不同的美学体系?
24. In addition, the style of some Black novels, like Jean Toomer's Cane, verges on expressionism or surrealism ; does this technique provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted , a theme usually conveyed by more naturalistic modes of expression ?
不仅如此，有些黑人小说(比如JT的甘蔗)的风格接近与表现主义和超现实主义;这种技巧是否为流行的主题提供了一个和谐的对应呢?这种主题刻画了黑人注意与之相抗争的命运，这是一个通常用更为自然主义的表现手法所表达的主题。
25. Black Fiction surveys a wide variety of novels，bringing to our attention in the process some fascinating and little-known works like James Weldon Johnson's Autobiography of an Ex-Colored Man.
《黑人小说》考察了极为广泛的一系列小说，在此过程中让我们注意到了某些引人入胜但却鲜为人知的作品，如詹姆斯。韦尔登。约翰逊(James Weldon Johnson)的《一个曾经是有色人的自传》(Autobiography of an Ex-Colored Man)。
26. Although these molecules allow radiation at visible wavelengths， where most of the energy of sunlight is concentrated，to pass through，they absorb some of the longer-wavelength，infrared emissions radiated from the Earth's surface，radiation that would otherwise be transmitted back into space.
虽然这些分子允许可见波长(visible wavelength)的辐射——阳光的绝大部分能量就汇集于此——不受阻挡地穿透，但它们却会吸收某些较长波长(longer-wavelength)，亦即从地球表面辐射出的红外发射(infrared emission)，这种辐射若不是二氧化碳的缘故就会被重新输送回太空。
27. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints-ways of feeling，thinking，and acting that “come naturally” in archetypal situations in any culture.
这些人类学家所归诸于生物进化的作用，不是规定人类行为的种.种细节，而是将各种限制强加于人类——即在任何文化的典型情景中都会“自然表露”的情感、思维、以及行动方式。
28. Which of the following most probably provides an appropriate analogy from human morphology for the “details” versus “constraints” distinction made in the passage in relation to human behavior?
以下哪一个选项最有可能为文章中所谈到的与人类行为有关的“人类行为细节”相对“人类所受限制”之间的差异，从人类形态的角度上提供了一个合适的类比?
29. A low number of algal cells in the presence of a high number of grazers suggested，but did not prove， that the grazers had removed most of the algae.
在存在大量食草动物的同时却只有少量的水藻花粉囊，这暗示出——但没能证明——食草动物已吞噬了大部分水藻。
30. Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net (net phytoplankton), a practice that overlooked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on , led to a de-emphasis of the role of grazers in subsequent research.
可能这样一个事实，那就是很多这样的最初的研究只是考虑了那些能够用网捞起来的大小的水藻，这样一个忽视了更小的浮游生物(而这些浮游生物我们现在知道是捕食者主要的食物)的做法，导致了在接下来的研究中对于捕食者的作用的贬低。
