状 语 从 句状 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 ． sinceC ． 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。Dwhen, 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.
