状语从句专项复习 状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。 时间状语从句 引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。时间状语从句中一般用一般现在时或一般过去时。 When , while, as都可解释为“当```的时候”但侧重点有所不同。 When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。 Eg: When (she was) walking along the street, she met her class teacher.

While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。 肯定句：I waited until midnight. 否定句：I did not leave until midnight. 注意点： 1）not until…在句首，主句用倒装 eg: Not until you had explained how did I manage to do it. 2) It is not until…that…引导的强调句 It was not until it was dark that he came back. 3. the minute, the moment, each time都可表示“一```就```” eg: The worker recognized the type of the machine the moment he saw it. 注意点： the minute, the moment, each ( every, next, the first) time作连词不和when 连用。 4．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```” eg: I had hardly/scarcely got home when it began to rain.
