篇2：role的用法总结

联合国在监督停火方面会发挥重要作用。
3、Jennifer responded with anger and played the martyr role.

“发挥作用”除了“play a role”还有别的译法吗?
国的控烟禁烟工作开展的比较晚，但通过立法来实施公共场所无烟化已是大势所趋，并得到社会和公众的共识。
译前分析：
1.词语翻译：
“控烟禁烟”: 控烟和禁烟意思重复，翻成”tabaco/smoking control“即可。
“……化”“……性”这类词的处理，首先，看看是不是可以变动词;第二，不能变动词时变形容词;第三，都不行的话才选名词
“实施”，动词隐词法，删掉，可以改写为“通过立法确保公共场所无烟化”
“大势所趋”：即主要趋势：a defining //an irresistible/inevitable trend
2. 句子翻译：
“中国的控烟禁烟工作开展的比较晚”：China’s tabaco/smoking control work started very late.
“但通过立法来实施公共场所无烟化已是大势所趋”的句式：“sth/doing sth has become 大势所趋”。
“通过立法确保公共场所无烟化”：to ensure that public space is smoking-free 或者to make/render public space smoking-free through legislation
“得到社会和公众的共识”，注意社会和公众意思重复，社会就是公众：the public has reached a consensus on
依然选择带有生命力的词做主语，并采用“拟人化”：While China is a late-starter in tobacco control…
译文：
As a late-starter in tobacco control endeavor, China is already seeing a defining trend of and a growing public consensus on building smoking-free public space through legislation.
注意：
“already“ 隐藏了转折，但体现了这个意思。
添加“endeavor”，语感更强
大器晚成：late-bloomer
第二句
Studies indicate that intestinal worms, which have been all but eliminated in developed countries, are ”likely to be the biggest player“ in regulating the immune system to respond appropriately.
译前分析：
句子结构：studies indicate that intestinal worms are likely to be the biggest player in doing sth.
”all but“ =” nearly“几乎
”be likely to be“：可能
翻译技巧：
我们知道中文翻到英文会采用“拟人化”，那么英语中拟人化的词，翻到中文，怎么处理呢?把名词转为动词，player的动词play：the biggest player就是play the biggest role in doing sth.
“在调节免疫系统作出适当反应方面发挥最大的作用”，转译为“最有利于”更简洁。
补充：
中文“发挥作用”，一定是“play a role”吗?
例句：
中国在推动全球经济复苏方面发挥很重要的作用。
1. play an important role in doing sth.(普通版)
2. China is an important player in facilitating global economic recovery. (采用拟人法)
3. China contributes significantly to global economic recovery. (contribute to 有利于，实际上就是发挥作用 )
再来看从句部分，”which have been all but eliminated in developed countries“：
从句是事实背景，“在发达国家几乎已经被消灭了的”这部分可以放在“蛔虫”的前面，作前置定语;如果太长，也可以选择单独成句。
译文：
研究表明，在发达国家几乎已经被消灭的蛔虫，可能最有利于调节免疫系统，使其做出适当反应。
第三句
The men do not call home with the truth, though. They send pictures of themselves posing next to Mercedes cars parked on the street, the kind of pictures that Mr. Jallow says he fell for so many years ago.
译前分析：
“call home with the truth“ : 在这里不能直译，要根据语境措辞。
“though”: 不过;注意用法，“，though”常常放在句末。
“fall for sth.”：被骗
译文多用四六格，表现出语言的张力。
译文：
不过，他们在给家人打电话时报喜不报忧/不以实情相告。他们寄回家的光鲜照片，都是站在街上停着的梅赛德斯车旁拍的，就连贾洛(Jallow)先生自己若干年前也曾对这样的照片信以为真。

An evaluation of the role played by remote sensing technology following the World Trade Center attack
Remote sensing technology has been widely recognized for contributing to emergency response efforts after the World Trade Center attack on September 11th, 2001. The need to coordinate activities in the midst of a dense, yet relatively small area, made the combination of imagery and mapped data strategically useful. This paper reviews the role played by aerial photography, satellite imagery, and LIDAR data at Ground Zero. It examines how emergency managers utilized these datasets, and identifies significant problems that were encountered. It goes on to explore additional ways in which imagery could have been used, while presenting recommendations for more effective use in future disasters and Homeland Security applications. To plan adequately for future events, it was important to capture knowledge from individuals who responded to the World Trade Center attack. In recognition, interviews with key emergency management and geographic information system (GIS) personnel provide the basis of this paper. Successful techniques should not be forgotten, or serious problems dismissed. Although widely used after September 11th, it is important to recognize that with better planning, remote sensing and GIS could have played an even greater role. Together with a data acquisition timeline, an expanded discussion of these issues is available in the MCEER/NSF report ”Emergency Response in the Wake of the World Trade Center Attack: The Remote Sensing Perspective“ (Huyck and Adams, ).

篇14：THAT用法总结
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：
第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
what about that book you borrowed from me last month？
请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子
that george！乔治那家伙！（含有轻蔑语气）
第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
that is what he told me.
what is that (which) you have got in your hand?
the price of rice is higher than that of flour.
2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）
he talked about the teachers and schools that he had visited.
i think it one of the most wonderful films that the film company has ever produced.
she has little information that is useful for our research.
is there anything that i can do for you?
请注意，that 在定语从句中作宾语时通常可省略。
the books (that) i sent you will help you in your studies.
第三、that 用作连词，引导名词性从句,状语从句和强调句。
1. that名词性从句。
①引导宾语从句。及物动词后的引导词that可省略。
i didn't expect (that) he could win the championship.
the teacher pointed out that tom was not working hard enough.
② 引导主语从句。通常采用it作形式主语的句型。
that the earth goes around the sun is known to everyone.
（it is known to everyone that the earth goes around the sun.）
③引导表语从句。
the trouble is that we are short of money.
④引导同位语从句。
引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：
the news that he resigned from office surprised us.
the idea that he holds is very common nowadays on campus.
2. that引导状语从句
①引导目的状语从句。
bring it nearer that i may see it better.
②引导结果状语从句。

on condition that you were lost in the desert, you should ask for help as soon as possible.
3. 引导强调句。

it is an ill wind that blows nobody good.
第四、that用作副词。
1. that用作普通副词。
i was that/so angry i could have hit him.

i will never forget the evening (that) / when we went to the theatre.
the house (that)/where i used to live has been knocked down.
第五，与that 有关的常见重要短语。
1. in that，意为“既然、因为”。
criticism and self-criticism is necessary in that it helps us correct our mistakes.

seeing that it is 8 o'clock, we'll wait no longer.
seeing that he was busy with his work, i didn't disturb him.

He shouted aloud as her ran along.他一边往前跑，一边高声地呼喊。
I was startled as he opened the door.他一开门，我吓了一跳。
as作连词，相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
2.引导原因状语从句，作“因为，由于”解，与because的用法相近。eg;
I must stop writing now，as I have rather a lot of work to do.我必须停笔了，因为我还有许多工作要做。
3.引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg：
As in your country，we grow wheat in the north and rice in the south.正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句)
When at Rome，do as Romans do.入乡随俗。(方式状语从句)
4.引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg;
Strange as it may seem，it is true.尽管这事看上去很奇怪，但却是真的。
Try as he might，Tom could not get out of the difficulties.不管怎样努力，汤姆还是摆脱不了困境。
四)as作关系代词。
1.引导限制性定语从句，用在“such...as”,“the same...as”，“as...as”等结构中，常译作“像...一样的人(或物)”，“凡是...的人(或物)”。例eg：
He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：
As is well known，oceans cover more than 70% of the earth.我们知道，海洋占地球面积的百分之七十以上。
篇16：that用法总结
that还常用以代替who, whom, which,但that...which中的that用做关系代词的先行词。
that可以用作连词
that用作连词时可引导主语从句、宾语从句、表语从句、同位语从句和状语从句。
that还常引导间接引语或形容词后面的.从句。
that在以it作形式主语的句子中或引导宾语从句、状语从句时常可省略。
