1．概念：在复合句中，用一个句子来充当时间状语的从句叫时间状语从句，说明主句动作发生的时间。常见引导词有 when, while, before, after, since, till / until, as soon as, whenever。 2．when 与 while：when 意为"当……时候"，从句动作可以是瞬间的，也可以是延续的，主从句动作可以同时发生，也可以先后发生（When he arrived, I was reading. / I was reading when he came in.）；while 意为"在……期间"，强调主从句动作同时发生或主句动作发生在从句动作进行的过程中，从句谓语必须是延续性动词，常用进行时（While I was training, I hurt my shoulder. / Don't talk while you are eating.）。 3．before 与 after：before 表示主句动作发生在从句动作之前（Think carefully before you make a decision.）；after 表示主句动作发生在从句动作之后（After he recovered, he trained for four years.）。 4．since：意为"自从……以来"，从句一般用一般过去时，主句用现在完成时（Since I learnt about his story, I have often thought of his example.）。 5．till 与 until：意为"直到……为止"，主句谓语是延续性动词时用肯定式，表示动作一直持续到从句动作发生（I waited until he came back.）；not...until 表示"直到……才"（He didn't begin training again until he recovered.）。till 与 until 基本可以互换，但位于句首一般用 until，till 不如 until 正式。 6．as soon as 与 whenever：as soon as 意为"一……就……"，表示主句动作紧接着从句动作发生（I will tell him as soon as he comes back.）；whenever 意为"无论何时，每当"，表示"每次从句的情况发生，主句的情况也随之发生"（Whenever he meets a problem, he tries to find a way out.）。 7．"主将从现"规则：主句用一般将来时，时间状语从句要用一般现在时表示将来（I will call you when I get home.）。主句是祈使句时（Please close the door before you leave.），或主句含有情态动词时（You can watch TV after you finish your homework.），从句同样要用一般现在时。 8．省略结构：when / while 引导的从句中，如果主语与主句主语一致，且从句含有 be 动词，可以省略主语和 be 动词，构成"连词 + 动名词 / 介词短语"结构（While (I was) travelling in England, I met a famous runner.）。 9．位置与标点：从句在前时，一般用逗号与主句隔开（When he arrives, I will tell him.）；从句在后时，中间一般不用逗号（I will tell him when he arrives.）。 四、易错提醒 1．when 与 while 的区别：while 后面的谓语必须是延续性动词，不能说 while he arrived，应说 when he arrived。 2．not...until 与 until 意思不同：I waited until he came. 表示"我一直等到他来"；I didn't go until he came. 表示"直到他来我才走"。 3．since 引导的从句用一般过去时，主句必须用现在完成时：Since I learnt it, I have often thought of it.，不能说 Since I learnt it, I often thought of it.。 4．时间状语从句中不能用 will 表示将来：要说 I will call you when he comes back.，不能说 when he will come back。 5．despite 是介词，后接名词或动名词：Despite his poor health...＝Although he was in poor health...，不能说 Despite his health was poor。 6．rob sb. of sth. 中介词是 of，不能说 rob sb. from sth.；同样，be diagnosed with 用 with，不用 by。 7．injure 的名词是 injury（伤，损伤），get injured 中 injured 是形容词；hurt 多指"疼痛、受伤"，injure 多指事故造成的损伤。 8．disappointed 修饰人，disappointing 修饰事物：His parents were disappointed. / The result was disappointing.。 9．let 后接动词原形：let his illness stand in his way，不能说 let his illness stands in his way。 10．however 表示"不管多么"时引导让步状语从句，后面紧跟形容词或副词：However hard the task is, ...；表示"然而"时是副词，常用逗号与句子隔开。 学科网（北京）股份有限公司 $
