人教版初中英语九年级第六单元语法

被动语态(二)

一般过去时的被动语态

一般过去时的被动语态是由“was/were+动词的过去分词”构成。如:

①He invented the telephone in 1876.

→The telephone was invented (by him) in 1876.

②Sam didn't find the book when he came into the room.

→The book wasn't found by Sam when he came into the room.

③They agreed on the building of a new car factory last month.

→The building of a new car factory was agreed by them last month.

④The students didn't forget his lessons easily.

→His lessons were not forgotten by the students easily.

【注意】(1)用直接宾语作被动语态的主语时,通常要在间接宾语前加上适当的介词。如:

①He sent me a photo yesterday.

→A photo was sent to me (by him) yesterday.

②Her father bought her a nice hat.

→A nice hat was bought for her  (by her father).

(2)某些动词,如:let, see, make, hear, watch, notice等在主动结构中作谓语,后可接不带to的动词不定式作为宾语补足语。但在变为被动语态时,省略的动词不定式符号to要还原。如:

①I saw him run out of the classroom.

→He was seen to run out of the classroom (by me).

②The man often makes his son do exercise.

→His son is often made to do exercise (by the man).

(3)某些不及物动词与介词或副词搭配构成动词短语,如:look after, take care of, cut down, laugh at, talk about, turn on, listen to, put off等后可接宾语,但变被动语态时应把动词短语看作一个整体,短语中的介词或副词不可省略。如:

①She always looks after the little girl.

→The little girl is always looked after (by her).

②All the students listen to the teacher carefully in class.

→The teacher is listened to carefully in class (by all the students).
