  虚拟语气用于表示与事实相反或者不可能实现的情况。它的语法结构为:
  ※ 当表示对过去事实的虚拟时,if从句的谓语为had done,而主句的谓语为would/could/should have done。如:

d/might do。如:
  If he smoked less, his cough might be well soon.要是他少抽一些烟,他的咳嗽就会好得很快。
  ※ 当表示对将来的虚拟时,if从句的谓语为should do/were/were to do,而主句的谓语为would/could/should do。如:
  If the lecturer were late, you would have to make a speech first.如果主讲人迟到了,你就得先发言。
  应当注意的是,如果条件从句中有were, should或者had,那么if可以省略,条件从句使用倒装语序。如:
  上句可以变为:Were the lecturer late, yon would have to make a speech first.
