条件用其他形式来表示

只看楼主收藏回复

疯豆:条件用其他形式来表示
She was ill, otherwise she would have been present at the meeting.她病了,否则的话就会出席会议了。(条件通过连词otherwiseor表示出来If she had not been ill...)
I told him to go there himself, but perhaps I should have gone together with him.我让他自己去那里,但也许我应该和他一道去。(连词but暗示条件)
Suppose you were in my shoes, what would you do假若你站在我的立场上,你会怎么办?(用supposesupposingproviding等词表示if)
To talk with her, you would know she could not hear well.如果你同她交谈,你就会知道她的听力不好。(动词不定式带有假设的意思,相当于If you should talk with her...)
Left to himself, he could not have finished the work.要是放任他的话,他是不可能完成工作的。(动词的-ed形式表示条件If he had been left to himself...)
提示:
在很多情况下,虚拟式已变成习惯说法,很难找出其暗含的条件。
You wouldn't know. 你不会知道。
I would like to go with you. 我愿意和你一起去。
三、虚拟语气在各种从句中的用法
虚拟语气除主要用于非真实条件句外,还可用在部分主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句之中。
A.名词性从句中的虚拟语气
主句中的动词、名词、形容词如表示要求、建议、命令或愿望等含义,与其相关的名词性从句(主语从句、宾语从句、表语从句和同位语从句)中的谓语动词要用虚拟语气。
1.主语从句中的虚拟语气
主语从句通常用于“It is +形容词名词动词的-ed形式+ that ...”结构。主语从句中是否用虚拟语气取决于所用的形容词或动词的-ed形式,其谓语动词常用“should +动词原形”(美国英语常省略should,只用动词原形)。
①表示建议或命令
It is important that we (should) work out a study plan.重要的是我们要制订出一个学习计划。
It will be better that we (should) meet some other time.最好我们在另一个时间见面。
It is suggested that each student (should) sing a song in English.有人建议每个学生都要唱一首英文歌曲。
It is demanded that he should leave at once.要求他立刻离开。
②表示惊讶
It is strange that he should have failed to see his own shortcomings.真奇怪他竟看不到自己的缺点。
It is a pityshame that I should be at school instead of lying here in hospital.真可惜,我应当在学校而不是躺在医院里。
It is natural that you should forget it first.你起先记不住是很自然的。
必背:
常见的要接含有虚拟语气主语从句的词
形容词:important, necessary, urgent, essential, vital, natural, strange, proper等
动词的-ed形式:arranged, suggested, ordered, required, desired, demanded, proposed等
It is necessary that the program (should) be loaded into the computer.有必要把程序输入电脑。
It is strange that he should have learned so much in such a short time.很奇怪他竟然在如此短的时间内学了那么多的东西。
It is desired that we (should) get everything ready by tonight.希望一切在今晚前准备就绪。
