英语被动句改法

英语的被动语态怎么改~

语态分为主动语态和被动语态，语态的变化也是在谓语动词部分。英语中使用的大部分语态是主动语态，下面是常用的被动语态。
(一) 被动语态的结构:由助动词be 加过去分词构成，时态通过be表现出来, 各时态结构如下表：
一般现在时被动：be（am，is，are）+done；
一般过去式被动：be（was，were）+done；
一般将来时被动：shall/will be+done；
过去将来时被动：should/would be+ done；
现在进行时被动：be（am,is,are) being+done;
过去进行时被动：be(was,were) being+done;
现在完成时被动：have/has been done;
过去完成时被动：had been done

1.foreign languages should be taught to us from an early age
2.students should be required to wear school uniforms
3.some courses ought to be taught to them over the internet on high school
4.more teachers should be recuited from other countries
5.classes ought to be offered on the weekends
希望你满意

1. who wrote it?
Whom was it written by? 或 By whom was it written?
2. why did no one inform me of the change of plans ?
Why I was not informed of the change of plans by anybody?
3. they waste a lot of time discussing unimportant things
改成.A lot of time is wasted to discussing unimportant things.是错的，discussing 仍然还保持原来的分词形式，此处作状语，应该改为：
A lot of time is wasted discussing unimportant things.
4. Didn’t they tell you to be here by six o’clock?
Weren’t you told to be here by six o’clock (by them)?
5. we shall then deal with it more fully.shall 为什么要改成will
It will be dealt with more fully.
Shall 表示将来只用于第一人称 I 和 we，改为被动后主语变成第三人称的 it，必须改为 will。
6. Have you looked into this matter?
Has this matter been looked into (by you)?
7. Is anybody attending to you ?
Are you being attended to (by anybody)? 你正受到注意吗？
8. I have taken careful note of your remarks.
Your remarks have been taken careful note of为什么错的
note of your remarks 是个结构紧密名词短语，不能身首分家，应该全部用作被动语态的主语如下：
Careful note of your remarks has been taken.
9. I expect you to keep him in the picture .这种不是应该expect后加to be …
两种改法;
1）He is expected to be kept in the picture.
2）You are expected to keep him in the picture.
前者句子中 keep 的逻辑主语是 he，也就是说他被留在画面上，所以要把不定时也改为被动，而后者的逻辑主语是 you，keep 的行为是由 you 实施的，因此不能用被动。
10. I strongly desire that he will be punished 怎么会是I want him to be punished.
这是根据意思改动的，但严格地说不是把原句转化为被动语态，而是换了一种说法；如果把从句 that he will be punished 作为被动语态的主语就不用那样改动了：
It is strongly desired that he will be punished.
11. Will they permit anybody to take the book out of the library?
两种改法（后者最佳）：
1）Will anybody be permitted to take the book out of the library?
2）Will the book be permitted to be taken out of the library?
12. we must not allow anybody to violate the interests of the people.为什么不是allow后面加to be.
主要是看非谓语动词与其逻辑主语之间的关系，如果是主谓关系要用主动，如果是动宾关系就得用被动。改法如下：
1) The interests of the people must not be allowed to be violated.
2) Nobody must not be allowed to violate the interests of the people.
13. They decided for building the power plant later.我觉得是the power plant is decided for building later .为什么错的
decide for 此处的意思“他们赞成随后建造一个发电厂”，你把动名词短语 building the power plant（建造一个发电厂）肢解开来，依然是身首分家，这样肯定是不行的。改为：
1) It was decided for building the power plant. (it 是形式主语)
2) Building the power plant was decided for.
14. My children might be led astray in the forest. I’m worrying about it.完全不会
第一句已经是被动语态：我的孩子们也许被人在树林中引入歧途。
第二句可以改为：It is being worried about (by me) 这件事正被担心.
