第1讲 用相应的过去时态表示“愿望”
考点1. wish之后的宾语从句中用虚拟语气
hope后面跟宾语从句时，只能用陈述语气：

wish后面跟从句时只能用虚拟语气，表示“愿望”，与事实相反或实现可能性不大。
本来是一般现在时的，要用成一般过去时；本来是一般过去时的，要用成过去完成时。

我希望我记得那个地址。（实际不记得，与现在相反）
② I wish you had written to him.

我希望你停止问愚蠢问题。（表达愿望，与将来相反）
hope与wish的其他用法：
wish和hope后面都可以跟不定式作宾语。

They wish to begin immediately after dinner.
wish后面可以跟双宾语和复合宾语，而hope不可以。
I wish you a happy birthday. 我祝你生日快乐。
I wish you to be happy. 我希望你幸福。
