语法考点之一 ：虚拟语气

考点1. If从句中的虚拟语气

1、与过去事实相反：从句sb had done，主句sb would(should, could, might)+ have done；

2、省略if，从句的语序用到装，即将were, had或 should移至主语的前面，但否定词not不前移。 3、与将来事实相反：从句sb did (should+do或were+to do)，主句sb would (should, could, might)+do。 4、错综条件句：主句与从句的动作发生在不同的时间段。

比如：从句对过去虚拟，而主句对现在虚拟，即从句sb had done，主句sb would(should, could, might)+do；

考点2：表示建议、要求、命令等动词如insist, order, command, suggest, advise, propose, ask, require, request, demand引导的从句及it引导的相应的分词、名词和形容词从句，谓语用（should)+动词原形。

考点3：It is +advisable, essential, important, imperative, incredible等从句，谓语用（should）+动词原形。

考点4：it is (high/about) time that的结构中，从句使用一般过去式。例如:

考点5：much as\尽管，虽然\引导让步状语从句，从句中用would have done表示假设。

考点6：if only, wish, as if/as though引导从句， 与过去事实相反：had + done； 与现在事实相反：动词过去式； 与将来事实相反：could/would + do

考点7：would rather/sooner从句中 使用一般过去式或过去完成式 分别表示对现在或过去的虚拟

考点8：lest / for fear that+(should ) +原形动词。
