知识点睛·考点透析 解决基本知识问题
考点一 虚拟语气用于条件状语从句
1. 虚拟语气用于非真实条件句
虚拟语气 从句谓语动词 主句谓语动词
与现在事实相反的假设 过去式 would/should/could/might+动词原形
与过去事实相反的假设 had+过去分词 would/should/could/might+have+过去分词
与将来事实相反的假设 过去式或 were to/should+动词原形 would/should/could/might+动词原形
If there were no water and air(Were there no water and air), all living things would die.
(与现在事实相反)如果没有空气和水,所有的生物都要死亡。
If he had taken my advice(Had he taken my advice), he would not have made such a
mistake.(与过去事实相反)如果他听我的劝告的话,就不会犯这样的错误了。
If it rained/should rain/were to rain tomorrow(Should it rain/Were it to rain), the sports
meet would be put off.(与将来事实相反)要是明天下雨,运动会就会推迟。
(在if引导的虚拟条件状语从句中,谓语动词含有had, were, should时,可以把if省略,将
had, were, should提到句首,变为倒装句。)
2. 错综时间条件句
当条件状语从句和主句表示的动作或行为所发生的时间不一致时,该条件句就被称为
“错综时间条件句”,动词的式要根据它所表示的时间作出相应的调整。

without,but for 等来表达。
