Question

英语：怎样分析那个句子是不是被动语态？我老是分不出来，有什么的方法知道它是？

Answer 1

(1) am/is / are+及物动词的过去分词 ,体现一般现在时的被动语态
eg. English is spoken in their country.
(2) was/were +及物动词的过去分词 ,体现一般过去时的被动语态
eg. Our school wasn’t built in 1990.
Were the trees planted by him?
(3) will /shall+ 及物动词的过去分词，体现一般将来时的被动语态
eg. A: I shall send my boy to school next September.
P: My boy will be sent to school next september.
(4) would/should +及物动词的过去分词，体现一般过去将来时的被动语态
(5) have/has +been done, 体现现在完成时的被动语态
eg. A: We have studied English for nine years.
P: English has been studied for nine years by us.
(6) had + been done, 体现过去完成时的被动语态
eg. A: They had produced 100 cars by the end of last year.

带情态动词的被动结构
其形式为：情态动词+be+动词过去式
�6�1 Can, could/ will,would/ shall, should/ may, might/ must/ ought to/ need/ have to.
�6�1 Eg. The baby can be taken good care of by the baby-sitter.
主动语态变被动语态应注意的问题
1.把主动语态变为被动语态时，应保留主动语态原时态。
Eg. She often cleans the house.
The house is often cleaned by her.
2.有些动词可以有双宾语，在用于被动结构时，有两种改法。
Eg. His mother gave him a present for his birthday.
= He was given a present by his mother for his birthday.
= A present was given to him by his mother for his birthday.
3. 当“动词+宾语+宾语补足语”结构变为被动语态时，
将宾语变为被动结构中的主语，其余不动.

Eg. Someone caught the boy smoking a cigarette(香烟）
=The boy was caught smoking a cigarette.
4. 在使役动词have, make, get, let以及感官动词see, watch, notice, hear
不带to的动词不定式等变为被动结构时，要加to

Eg. Someone saw a stranger walk into the building.
=A stranger was seen to walk into the building.
5.有些相当于及物动词的动词词组，
如“动词＋介词”，“动词＋副词”等,也可以用于被 动结构, 但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。
Eg. The meeting is to be put off till Friday.

The homeless children will be taken good care of.

Answer 2

被动语态是指一些动作发生，但主语不能主动去做（比如比赛举行：是the game was held而不是the game hold） 被动句的一般形式是be（am/is/are/was/were)+done((动词的过去分词）给你几个例子： We plant trees in spring every year 被动：the trees are planted (by us) every year She posted the letter yesterday. 被动：the letter was posted (by her ) yesterday本回答被网友采纳

Answer 3

一个句子里只能有一个谓语动词，从句可以有多个，多少个句子有多少个谓语动词，如果一个句子里出现两个动词，如Be +ved 那就是被动了，be 是谓语动词，ved表示被动

Answer 4

如果你能翻译理解句子的意思，就很好办了，主动语态中主语是动作的发出者，在被动语态中主语是动作的承受者。如果不能理解，只能看谓语动词了，一般被动的形式是be
+ved
。

Answer 5

当强调动作承受者，不必说出执行者或含糊不清的执行者时，多用被动. 一般现在时
