1、【解析】 where引导的是地点状语从句。这位著名的科学家在他的出生地长大,1930年他来到上海。因为在从句中有表示时间的介词短语in 1930,所以可以排除when和whenever; wherever引导让步状语,意思是“无论在哪里”,与句意不符。例4、_, I have never seen anyone whos as capable as John.A. As long as I have traveled B. Now that I have traveled so muchC. Much as I have traveled D. As I have traveled so mu
2、ch【解析】 这是一个让步状语从句。as在引导让步状语从句时,要把形容词或副词放在它的前面。如果是名词,一般不加冠词。如:Child as he is, he has learned two thousand new words .As long as“只要”引导条件状语从句;Now that“既然”引导原因状语从句;As“因为”引导原因状语从句。虽然我走过了那么多地方,我从来没有见过像约翰这样有能力的人。例5、In such dry weather, the flowers will have to be watered if they_.A. have survived B. are to
3、 survive C. would survive D. will survive【解析】 这是一个条件状语从句,主句用了一般将来时态。在条件状语从句中,一般不能使用将来时,但能和be to do的形式连用,所以应填are to survive。在如此干旱的天气里,如果你想要花成活,就得给它们浇水。例6、The WTO cannot live up to its name _ it does not include a country that is home to one fifth of mankind.A. as long as B. while C. if D. even though
4、答案选C。【解析】 从句子意思可知,是一个条件状语从句。as long as“只要”引导条件状语从句经常用肯定句,所以要填if。如果WTO不包括一个占人类五分之一的国家,它就名不符实了。例7、She found her calculator _ she lost it.A. where B. when C. in which D. that答案为A。【解析】 这是一个地点状语从句,意思是“东西是在丢的地方找到的。”in which用于定语从句中,其前必须有先行词。这个句子中没有先行词,所以不能填in which。例8、Im going to the post office. _youre th
5、ere, can you get me some stamps?A. As B. While C. Because D. If【解析】while引导时间状语从句,意思是“当时”。这句话的意思是“当你在那儿的时候,是否能给我买一些邮票?”as虽然也可以引导时间状语从句,但其意思是“一边一边”;because引导的是原因状语从句;if引导的是条件状语从句,对方已经说明要到邮局去,不能再作假设。 例9、You should make it a rule to leave things _you can find them again.A. when B. where C. then D. there
6、【解析】where引导地点状语从句。这句话的意思是“你应该作出一个规矩,把东西放在你能再找到它们的地方。” 例10、Well have to finish the job, _.A. long it takes however B. it takes however longC. long however it takes D. however long it takes答案选D。【解析】however引导让步状语从句。要用陈述句的语序。Presentation常用连接词名称常用连词1.时间状语从句when, while, as, before, till, until, once, by t

11、.When,as,while用法区分:1)当从句的动作发生于主句动作之前,只能用when 引导这个从句,不可用as 或 while。When you have finished your work, you may have a rest.2)如从句表示随时间推移,连词能用as,不用when 或while。As the day went on, the weather got worse. 练习1. last week, she lived a quiet and happy life in that area.

17、须用逗号或分号与主句分开,引起的从句对主句加以解释。有时,for引起的从句并不表示原因,而是表示一种推断或解释,而because则不能。Someone in the house must be ill, for a doctor has just come out. 练习:1. Liquids are like solids they have a definite volume.
