高三英语高考复习：语法系列课件之状语从句.ppt

* * 高考语法复习系列十三 状 语 从 句 状语从句考点 1、各种从属连词的含义及用法比较； 2、no matter wh- 与 wh-ever 引导的从句的区别； 3、状语从句的时态问题； 4、状语从句的倒装问题； 5、状语从句与其它从句的区别。 1、时间状语从句 问题1： Don’t be afraid of asking for help it is needed. （03全国卷） A．unless B．since C．although D．when 根据句意，此处只能为时间状语从句，故答案为D。 unless 引导条件状语从句，意为“除非”；although 引导让步状语从句，意为“虽然”；since 虽引导时间状语从句，但意思为“从…以来”，这些都与题意无关。引导时间状语的引导词很多，复习when 时要注意比较它与while 与 as 的区别。 D when, while, as 三者的具体用法关键在于动作发生的时间及从句的动词。while 表时间，从句需用延续性动词，不用瞬间动词；when 表时间，从句既可用延续性动词，又可以用瞬间动词；as 表时间，与when 相似，但侧重强调主、从句动作同点或同段进行，可用延续行动词的一般过去式表式过去进行时。when, while 后还可以接分词短语。when 作并列连词，表示一个动作在发生时，另一个动作接着发生，这时就不能用while、as。 I was walking on the street when suddenly someone patted me on the shoulder. while 作并列连词，表示两种情况对比。 He was playing the guitar while his sister was watching TV. 问题2：1) — Was his father very strict with him when he was at school? — Yes. He had never praised him he became one of the top students in his grade. （03北京春季） A．after B．unless C．until D．When 2) Simon thought his computer was broken ________ his little brother pointed out that he had forgotten to turn it on. （05北京春季） A. until B. unless C. after D. because C A until / till “直到……止”(肯定句，主句是延续性动词); not…until “直到……才”(否定句，主句是终止性动词); until 可用于倒装句和强调句，till不用于句首。 Not until I returned did she finish her homework.

(05广东卷) A. after B. before C. when D. then 2、He made a mistake, but then he corrected the situation ______ it got worse. （03北京） A. until B. when C. before D. as B before 从句是高考中的一大热点，从时间概念上不难作出判断。注意它的翻译：在肯定句中一般翻译成“…（主句的动作）才…（从句的动作）”，如题1；或“还没有…（从句的动作）就…（主句的动作）”，如题2。 C 问题4： — Did you remember to give Mary the money you owed her? — Yes, I gave it to her ____
