Introduction状语从句典型例题解析例1、Generally speaking, _________ according to directions, the drug has no side-effect.A. when taking B. when taken C. when to take D. when to be taken答案为B[解析] 这是一个由when引导的时间状语从句,原句应为"Generally speaking ,when it is taken according…"由于take用被动时,主从句主语一致,因此从句中的it was可以被省略,简化为when taken…分词短语作状语,而选A、C时则缺乏主语译文：通常地说,当这药按照指导说明被服用的话是没有副作用的例2、—Dad, I've finished my assignment.—Good ,and _________ you play or watch TV ,you mustn't disturb me. A. whenever B. whether C. whatever D. no matter答案为B。

[解析] no matter不能直接引导让步状语从句,应用no matter + wh族疑问词方可,故排除D；尽管A、C都有"无论"的意思,但只有B项whether可与or连用,表示选择,即"无论你玩还是看电视,不许打扰我"例3、The famous scientist grew up _______ he was born and in 1930 he came to Shanghai.A. when B. whenever C. where D. wherever答案为C[解析] where引导的是地点状语从句译文：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 who's 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 much答案为C。

[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"引导原因状语从句译文：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 survive C. would survive D. will survive答案为B[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译文：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答案选C。

As B. While C. Because D. If答案为B[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。
