　　7. 关于虚拟语气(仅作参考)

　　“式”(MOOD)是个语法范畴，它是表示语气的动词形式。英语动词有三种式：陈述式(INDICATIVE MOOD),祈使句(IMPERATIVE MOOD)和虚拟式SUBJUNCTIVE MOOD)。陈述式一般用来叙述事实或提出疑问，广泛用于陈述句、疑问句、感叹句。可以说百分之九十五的英语句子用的都是动词陈述式。所介绍的动词时、体、态等形式都是就陈述式而言的。祈使式主要用于祈使句，是说话人向对方下达命令、指令、提出要求、劝告等所用的动词形式。例如：

　　Go back to your seat, please.

　　Take a ten-minute break now.

　　Don't walk on the grass.

　　Don't write in your book.

　　Let's rest for a while now.

　　Let's not watch TV tonight.

　　虚拟式是说话人为表示一种假设的情况、一种主观的愿望，即认为动词所表示的动作或状态并非事实或仅是主观设想时所用的动词形式。虚拟式在现代英语中不是以个重要的语法范畴。现代英语表达虚拟式的口气可采用多种多样的语法手段，如采用一般过去时、过去进行体，过去完成体：

　　It's time we had a rest.

　　I was wondering if you would let me use your car.

　　How I wish I had gone there with you!

　　还可采用情态助动词的过去时形式加动词不定式或不定式完成体：

　　I should/would be there by now if I had started earlier.

　　He would have been there by now if he had not missed the train.

　　当然也可采用一种特殊
