　　含时间状语或时间状语从句的时态断定

　　1.

　　(典型例题精选 )When the old man

　　to walk back to his house, the sun

　　itself behind the mountain.

　　A. started; had already hidden

　　B. had started; had already hidden

　　C. had started; was hiding

　　D. was starting; hid

　　[考场错解]

　　D

　　[专家把脉]

　　如果误解为"was/were doing…when…”(即将……突然……)句型，就会错选D。从句意看hide的动作在start之前就已经开始了，应当用过去完成时来表示过去的过去。

　　[对症下药]A

　　2.

　　(典型例题精选 )Scientists think that the continentswhere they

　　today.

　　A. aren't ; are

　　B. aren' t ; were

　　C. weren ' t ; are

　　D. weren ' t ; were

　　[考场错解]

　　A

　　[专家把脉]

　　单纯看时间状语好像是用现在时态，但语境告诉我们的是今天各个大陆板块的位置与过去的不同，因此，前者是一般过去时，后者才是一般现在时。

　　[对症下药]

　　C

　　3.

　　(典型例题精选 ) Let' s keep to the point or we

　　any decisions.

　　A. will never reach

　　B. have never reaehed

　　C. never reach

　　D. never reached

　　[考场错解]

　　C

　　[专家把脉]

　　考查“祈使句+or/and+陈述句”结构的用法。一般陈述句中是一般将来时。根据本句的意思：咱们还是抓住要点(别跑题)，否则就永远得不出结论(做不出决定)，应选一般将来时。

　　[对症下药]

　　A

　　4.

　　(典型例题精选) That was really a splendid evening. It' s years

　　I enjoyed myself so much.

　　A. when

　　B. that

　　C. before

　　D. since

　　[考场错解]

　　A

　　[专家把脉]

　　看起来似乎是连接词的选择。本题暗含了句型“It is/has been+一段时间+since从句”，且 since从句中一般用一般过去时，如果前面是Was，则since从句中用过去完成时。

　　[对症下药]

　　D

　　专家会诊

　　固定句式中的时态和语态的情况：

　　1．在I fI unless，even if引导的条件状语从句中，在when，until(till)，as soon as， the moment， once引导的时间状语从句中，no mater what/who/ which?when/where，how或whatever，whoever， whichever/whenever/wherever/however弓}导的让步状语从句中，如果主句是将来时(往往出现will/ shall/Call/must)或主句是祈使句，从句用一般现在时代替一般将来时。如： I’ll not go unless I am invited． Tell him the hews as soon as he comes．2． “be+to do"表示拟订或计划中将发生的行为或按职责义务必须去做的事情；“be about to do”表示即将发生的事，句中一般不使用时间状语。如

　　All the questions areto be answered at once．(表示拟订的事情)

　　No one is to leave the room without the permissionof the police．(表示按职责必须做的事)

　　They are abouttoleavetonight．(错误，去掉tonight)

　　3．语境中的过去时，往往表示“刚才，刚刚”的意思，暗示现在已“不再这样”。如：

　　I didn’t know you were here．(说话时已经知道了你在这儿)

　　I never thought he would do that．(说话时已经知道了他会这样做)

　　4．表示愿望、打算一类的词，如hope，expect， mean，intend，want，think，suppose，want等，其过去完成时表示过去未曾实现的愿望或意图。如：

　　I had hoped to see more of New York．(实际上没能实现)I had mean to help you，but I Was too busy at that moment．(本来打算帮你，但没有实现) I had thought that he would come tomorrow．(结果是他明天不能来)

　　5．三个特殊句式的固定时态。

　　(1)This/It is the first/second…time+that从句。从句中一般用现在完成时，前面的is为Wa$时，贝0用过去完成时。如：

　　This is the first time I hare come to the famous city.

　　It was the forth time he had made the same mistake.

　　(2)It is/has been+一段时间+since从句o since从句中一般用一般过去时，如果前面是wag，则 since从句中用过去完成时。如：

　　lt WaS ten years since we had had such a wonder ful time．(3)It+be+一段时间+before从句。如果主句用将来时，从句用一般现在时表示将来，意思是多长时间后即将发生某事；如果主句用过去时，从句也用过去时，意思是多长时间后发生了某事。如：

　　h won’t be long before he succeeds．(要不了多久他就会成功)

　　h was ten years before they met again．(十年后，他们又见面了)
