10、在It’s important (imperative, necessary, essential, vital, desirable, advisable, better) that…句型中,that 引导的从句用虚拟语气,即谓语动词用should + 动词原形,should可以省略。这个句型表示说话人的意见、要求等。

For example:

It is essential that there should be enough food and clothing for the winter.

It is desirable that your wedding be postponed until next July.

It is imperative that the board chairman be present at the board meeting.

另外,在一些习惯用语中也有虚拟语气的形式。但最好把这些习惯用语作为一种句型来记住。如:

May you be happy!

May you succeed!

Long live the People’s Republic ofChina!

Everybody leave the room!

You had better not resign.

I would rather not tell you.

总之,虚拟语气是英语中的一个难点,因为虚拟语气的用法和句型较多,动词的变化比较复杂。在学习的时候要逐个过关。同时,也要善于发现虚拟语气的规律。根据动词的变化,大致可以把虚拟语气分为三种:

    一种是动词用过去式,过去分词式,或过去将来式,这主要是用if…, wish, suppose的情况;

    一种是动词用should+动词原形(should可以省略),这主要用于表示建议、要求、命令等意思的动词或名词后面所接的从句,以及It is important (necessary) that…后面所接的从句;

    一种是动词用过去式,如It is (high) time (that)…和I would rather 后面的从句。同学们还可以自己总结适合自己的规律,如把虚拟语气句型可以分为用于简单句、条件状语从句、宾语从句、主语从句、表语从句、定语从句、同位语从句等。
