4、(high) time后边的从句中用过去时。”例：It is time that we had a rest.二、语态：1. 语态是表示主语与谓语之间关系的一种形式。英语有两种语态：主动语态和被动语态。考查时态与语态的题通常结合在一起，尤其是被动语态，除了注意它的一般时态之外，还要注意它进行时态及完成时态的变化。如：He told me that a highway was being built here.他告诉我这里正在建造一条高速公路。2. 另外还需注意有些动词，其形式虽是主动，但具有被动的含义。1）当感官动词作系动词时,例如：Good medicine tastes bitter.良药

5、苦口。This material feels very soft.这种衣料摸起来非常柔软。2）还有一些及物动词作不及物动词时，也可以表示被动含义，如：This pen doesnt write well.这支笔不好使。此类动词不多，常见的有cut, lock, open, peel, read, sell, shut, wash, wear, write 等。练习：1.

10、面接to do。情态动词后接完成时的用法:情态动词用来表示能力、允许、许诺、可能、必须、劝告、意愿等概念或态度。2must现在完成时结构：这一结构表示对过去一个动作比较有把握的猜测。例：I believe he _ an accident, otherwise he would have arrived on time.A. would have had B. could have hadC. should have hadD. must have had答案为D。3should (ought to )have done用来表示本来应该做却没有做的事情。例：Im sorry I couldnt

12、 have boughtC. can buy D. could buy答案为A。玛丽本来可以买那件大衣的，但是她把钱借给一个更急需的邻居了。四、虚拟语气：虚拟语气是动词的一种特殊形式，用来表达说话人的愿望、请求、意图、建议、惊奇、设想等。虚拟语气是英语语法的难点，考生必须熟练掌握。以下从五个方面介绍。1虚拟条件句中虚拟语气的运用：虚拟条件句从时间上又分为与现在事实相反，与过去事实相反，与将来事实可能相反三种情况。表示与现在事实相反的，if从句用过去式，主句用would（或could, should, might）加原形动词。与过去事实相反的，if从句用过去完成时，主句用would（或could

13、, should, might）+have done结构。与将来事实可能相反的，if 从句用should (或were to)加动词原形，主句用would加动词原形。1）If a better material _, the strength of the part would have been increased.A. had been usedB. had been usingC. being used D. using根据前面的讲解，正确答案为A。 2）Had the weather been good, the children _ out for a walk.A. had gon

14、e B. could have gone C. would go D. went答案为B。与过去的事实相反。当if从句中含有were, had, should这三个词时，if可以省略，主谓倒装。2某些动词后的宾语从句以及某些名词后的表语或同位语从句中虚拟语气的运用，这些动词或名词包括：suggest(suggestion),propose(proposal),advise (advice),demand, insist, order, request, require, recommend, desire, ask, decide等表示建议、命令或要求的词。在这些从句中，谓语形式为should加动词原形，should可以省略。例：The generals
