关于被动语态和主动语态.
主动改被动:
They are doing the project now.
正确是:The project is being done by them now.
为什么要加个being?
Tom has cleaned the room.
正确的是:The room has been cleaned by Tom.
为什么要加个been?
被动改主动:
The house was built in 1990.
正确的是:People built the house in 1990.
为什么不用加个were在built前面?
Things are stolen from the supermaket everyday.
正确的是:People steal thing from the supermarket everyday.
为什么要这么改?
The question is being discussed by a group of students.
正确的是:A group of students is discussing the question.
同上的问题.
请用比较白化的话来回答,英语里的术语看着混乱.
希望回答完以后能够出几道类似的题目让我改改喔,谢谢大家.
被动语态(一般现在时)
主动语态变被动语态时,主动语态句中的宾语变成被动语态句中的主语,主动语态句中的主语成为被动语态句中的动作的发出者.
1.一般现在时 is\am\are+P.P(过去分词)
2.一般过去时 was\were+P.P
3.一般将来时 will be+P.P
4.现在进行时 is\am\are+being(固定不变)+P.P
5.过去进行时 was\were+being(固定不变)+P.P
6.现在完成时 have\has been+P.P
7.过去完成时 had been+P.P
1.表示正在进行的动作,
现在进行时 is\am\are+being(固定不变)+P.P
2.现在完成时 have\has been+P.P,
3.people 和build 之间是主动关系
4.东西被偷了,那一般当然是人去偷啊,所以变成主动语态,就用人作主语了.
5.一组同学正在讨论这个问题.
练习:
1.主动:The children gave the foreign guests a warm welcome.
被动:The foreign guests were given a warm welcome by the children.
孩子们热烈地欢迎外宾.
2主动:People regard him as brilliant.被动:He is regarded as brilliant by people.
人们认为他很有才华.
3.主动:Somebody had cleaned my shoes.被动:My shoes had been cleaned by somebody.
有人早已把我的鞋子擦了.
4.主动:No one has ever beaten him at tennis.
被动:He has never been beaten at tennis.
