31、me, no sooner than, hardly (scarcely) when, every time等引导。1考查when, while, as引导，表示“当时候”.【考例】m，_shall we have lunch? We will have it when your dad_.A. when；returnsB. where returnsC. where；will return D. when；will return答案A解析 答语中when引导了一个时间状语从句，主句用了一般将来时态，所以从句用一般现在时态，可见正确答案在A与B之中。既然答语用了时间状语来回答，可见问句询问的也

32、一定是时间，从而确定正确答案为A。2. before 的用法：before的本意为“在之前”，根据具体语境还可理解为“还没来得及/还没有就，趁着还没就，不知不觉就，才”等。如：【考例】Could you please give me your e-mail address _you go?A. as soon as B. before C. after D. until答案B解析这四个词(组)都可以引导时间状语从句，as soon as一就before在之前；after在之后；until直到才。分析句子可以看出句意为“在你走之前把你的电子邮件地址给我好吗?”2until 和till 的用法：与

33、肯定式的主句连用，主句谓语必须是延续性动词，till/ until表示“直到”；与否定式的主句连用，且主句谓语是非延缓性动词时，till/ until表示“直到才”。其强调句型为“notuntil” ，位于句首时要采用倒装形式。如：【考例】Hurry upThe bus is coming Oh。noWe mustnt cross the street _the traffic lights are green.Aafter B. since C. while Duntil答案D 解析本题应从句意人手。until常用于否定句中，构成notuntil结构，意为“直到才”，该句意为“直到交通灯变绿

34、，我们才能穿过马路”。 -Look! Here comes our school bus. -No hurry. Dont get on it _it has stopped.A. until B. after C. since D. whenA解析句中有dont，可想notuntil为固定结构，意为“直到才”。二、对条件状语从句的考查 引导条件状语从句的从属连词有if ,unless(=if not如果不，除非)，as/so long as ,while(=as long as 只要)，supposing(that),provided/providing(that),in case(假使)，
