课堂探究

  1.What do you think would happen if tomorrow there was suddenly no rice to eat?

  如果明天突然没有米可吃了,你认为会发生什么事呢?

  剖析:1)do you think属于插入语,置于特殊疑问词之后。句子的主干应是What would happen?如:

  Who do you think will come to help us?

  你认为谁将来帮助我们?

  2)该句中用了虚拟语气,表示与将来事实相反的假设。从句用一般过去时,主句中用"would/could/might/should+动词原形"。

  要注意在使用虚拟语气时谓语动词的形式:

从句谓语 主句谓语 现在情况 一般过去时(be要用were) would/could/might/should do 将来情况 一般过去时should do were to do would/could/might/should do 过去情况 过去完成时,即had done would/could/might/should have done   注意:如果if条件句中含有were,should,had,则可以将if省略,把were,should,had提到主语的前面。如:

  Were I you,I wouldn't make him angry.

  如果我是你,我不会让他生气。

  Should he come,I would let you know.

  如果他来,我会让你知道。

  Had they said sorry to me,I would have forgiven them.

  如果他们向我道过歉,我就原谅他们了。
