Summary

1. Subjunctive Mood In If -clauses 表示与事实情况相反

表示与现在事实情况相反(present) 条件从句的谓语形式

过去式(did/were) (be常用

were)

过去完成式(had+done) 主句的谓语形式

would/could/might /should+ do

would/could/might/ should+have done

would/could/might/ should+ do

表示与过去事实情况相反(past)

表示与将来事实情况相反(future)

2、Tips. ①过去(did)/(were) ②should + do

③were to do

1）Would,could,should and might are often interchangeable, but with some differences in meaning. would → intention; plan

could → ability; possibility

might → probability

should → ought
