ket语法:不同时态下动词的被动语态变化

来源:小编 编辑:小编 日期:2023-01-11 18:11:17

在之前的语法精炼栏目中,备考君已经和大家整理了八种时态,限于篇幅,没有详细说明时态会对句子中的其他成分起到什么作用。学生也知道,在英语句子中,谓语和动词是受时态变化影响最大的。

动词在不同时态下的被动语态变化

1. 通常现在的被动语态:is/am/are V-ed。比如:English is widely spoken all over the world.

2. 过去的被动语态通常是:was/were V-ed。比如:The underground was built five years ago.

3. 一般未来的被动语态:①will/shall be V-ed。比如:The decision will be made at the meeting tomorrow.We shall be punished if we break the rule.②be going to be V-ed。比如:The problem is going to be discussed at the meeting tomorrow.③be to be V-ed。比如:The sports meet is to be held on April 20.

4. 当前完成时的被动语态:have/has been V-ed。比如:Many a house has been built in our city so far.

5. 当前进行的被动语态:is/am/are being V-ed。比如:The stadium is being built in the north of our city at present.

6. 在变被动语态时,短语动词不能丢失介词或副词,因为它是一个不可分割的整体。The nurse took good care of the patients.→The patients were taken good care of by the nurse.

7. 双宾语句子的被动语态:当双宾语句子变成被动结构时,一个句子可以变成主语,另一个句子(多为直接宾语)仍然保留在谓语后面。比如:My aunt gave me a bike.→I was given a bike by my aunt.→A bike was given to me by my aunt.

8.当含有复合宾语的句子变成被动结构时,宾语的补语相应地变成主语的补语。需要注意的是,主动语态中没有宾语补语的补语。to不定式,在变成被动语态时应带有to。

比如:

(1)The boss made his workers work hard for him every day.→His workers were made to work hard for him every day by the boss.(2)Everyone calls him Big Brother.→He was called Big Brother by everyone.(3)I saw him going into the supermarket.→He was seen going into the supermarket.

当含有情态动词的句子变成被动语态时,可以变成:情态动词 be/have been V-ed。比如:They must like the book very much.→The book must be liked very much by them.She must have known the truth.→The truth must have been known by her.

除上述动词语态变化外,还有一些另类动词,不用于被动语态。

主要词汇不用于被动语态。

以下,结合之前总结过的动词的其它语态变化,我们来锻炼一下语态转换的应用:
