【考点诠释】
一、时间状语从句
在时间状语从句中,通常要用动词的一般现在时态表示将来时,用一般过去时表示过去将来式。时间状语从句常用连词有: when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
考查when, while, as引导,表示“当……时候”.
【考例】一Mum,____shall we have lunch?—We will have it when your dad_______.
A when;returns B where returns ;will return ;will return
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
和till 的用法:与肯定式的主句连用,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“not…until”,位于句首时要采用倒装形式。如:
【考例】1、一Hurry bus ing.
——Oh。 mustn't cross the street ____the traffic lights are green.
A. after B since C while
2、The kids didn't start to fly kites in the playground _______the rain stopped.
A. if B. until C. whenever
3、--Look! es our school bus. --No hurry. Don't get on it _____it has stopped.
A. until B. after C. since D. when
A.[解析]句中有don't,可想not...until为固定结构,意为“直到……才……”。
三、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),on condition that(在……的条件下)等。如:
【考例】__you go to bed earlier, you won't feel tired in the mornings.
A. Unless B Because
2、You won't pass your exams ___________ you work harder.
A. when B. if C. unless D. after
四、对让步状语从句的考查
用来引导让步地点状语从句的从属连词有:though,although,even if/though, while(虽然、尽管),for a11(that)(尽管)whether...or(不论/不管……还是……))以及“疑问词+ever(whatever,wherever,whoever,however,)”和“no matter +疑问词”等。
