在选择时 见到什么判断为虚拟啊 选项又该怎样选呢
解题思路: 如下
解题过程:
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
If 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句(如在阴天说if it rains, we would not go out),反之为非真实条件句,要用虚拟语气。
三假设条件一般为:
1) 与过去事实相反,从句谓语动词用过去完成时,主句动词为情态动词+完成时态。
e.g. If I had come here yesterday, I would have seen him.
2) 与现在事实相反,从句谓语动词用一般过去时,主句动词为情态动词+动词原形。
e.g. If I were a teacher, I would be strict with my students.
3) 与将来事实可能相反,从句谓语动词用过去将来时,主句动词为情态动词+动词原形。
e.g. If it should snow tomorrow, they couldn’t go out.
主句谓语动词为情态动词(should, would, could)+和相应的从句一致的动词形式。
四 if 条件句中如果有were, should, had, 可以省去if, 并使用倒装句序。
l 宾语从句中的虚拟语气
一 wish后面宾语从句中的虚拟语气:根据从句的意义来判断:
1.与现在和将来相反的事实,从句谓语动词用过去时态;
e.g. I wish I were a bird.
2.与过去相反的事实,从句谓语动词用过去完成时态。
e.g. I wished he hadn’t done that.
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。
e.g. I insisted that he (should) go with them.
He suggest that a meeting (should) be held to discuss the matter.
He demanded that I (should) help him.
注意:当insist 表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气。
e.g. He insisted that he was honest.
The look on his face suggested that he was quite satisfied with what I had done for him.
三 would rather + 从句
在这种结构中,从句的谓语动词用过去形式表示虚拟。
e.g. I would rather you did this instead of me.
l 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有: necessary, good, important, right, wrong, better, natural, proper, funny, strange, surprising, etc.
e.g. It is necessary that we should get everything ready by the end of the week.
It’s natural that he should feel hurt.
一些名词也可用于此结构中,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。
e.g. It is desired that the building of the house be completed next month.
三 It is time (about time/ high time) that…..(过去时动词形式或should + 动词原形)…..
e.g. It is high time I went home now = It is high time I should go home now.
l 表语从句、同位语从句中的虚拟语气
在suggestion, proposal, order, plan, idea, advice, decision等需要具体内容解释的名词后的表语从句、同位语从句中,要使用虚拟语气、其谓语动词为: should + 动词原形。连接从句的that 不能省略。
e.g. My suggestion is that we should go there at once.
What do you think of his proposal that we should put on a play at the English evening?
The proposal that we should stay longer in Shanghai was rejected.
