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)

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****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?

top students in his grade. (03北京春季)

C
A
until / till “直到……止”(肯定句,主句是延续性动词);

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.

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。
