1) 概念
[Subjunctive Mood]
中文译作"虚拟语气"。它是一种动词形式,表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。
2) 在条件句中的应用
条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。
●虚拟语气的使用范围及判断
一、虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。也可用于主语从句、表语从句、宾语从句等。
二、if条件状语从句中虚拟语气的判断
判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气。
判断这个假设是与哪个事实相反。通常有三种情况:①与过去事实相反。②与现在事实相反。③与将来事实可能相反。
三、“后退一步法”
后退一步法是指在准确地判断了该句与哪一事实相反后,按虚拟语气的后退一步法处理从句谓语动词的时态。即:在非真实条件状语从句中,谓语动词按正常情况“后退一步”。也就是:
①与过去事实相反,在从句中用过去完成时形式表示。
②与现在事实相反,在从句中用过去一般时形式表示。
③与将来事实可能相反,在从句中用过去将来时形式表示。
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。
例:If I had come her yesterday, I would have seen him.
If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn’t go out.
四、注意事项
①if条件句中如有were, should, had,可以省去if,并使用倒装语序。
②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
●宾语从句中的虚拟语气
一、wish 后面宾语从句中的虚拟语气
wish 后面宾语从句中的虚拟语气,按“后退一步法”处理从句的谓语动词。注意:与哪个事实相反,不能以主句的时态为判断依据,而是根据从句的意义判断。
二、表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有:advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest等。
注意:当insist表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气。
The look on his face suggested that he was quite satisfied with what I had done for him.
He insisted that he was honest.
三、would rather +从句
在这种结构中,从句的位于动词用过去形式表示虚拟。
I would rather you did this instead of me.
●主语从句中的虚拟语气
一、It be + 形容词 + that ...(should)...
用于该句型的形容词是:necessary, good, inportant, right, wrong, better, natural, proper, funny, strange, surprising .
一些名词也可以用于 在该结构中。如:a pity, no wonder....
二、It be + 过去分词 + that ...(should)....
用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如:desired, suggested, requested, ordered, proposed等。
三、It is time(about time, high time)that ...(过去式动词形式或should+动词原形)....
It is high time I went home now. = It is high time I should go home now.
●表语从句、同位语从句中的虚拟语气
在suggestion, proposal, order, plan, idea, advice, decision等需要有内涵的名词后面的表语从句、同位语从句中,要使用虚拟语气。其谓语动词应用:should+原形动词。另外连接从句的that不能省略。
例:My suggestion is that weshould go there at once.
What do you think of his proposal that we should put on a play at the English evening?
