中考網(wǎng)整理了關(guān)于2023年中考英語復(fù)習(xí):There be句型的用法,希望對同學(xué)們有所幫助,僅供參考。
There be 句型的用法
1)基本結(jié)構(gòu):
肯定句式:be +done (及物動詞的過去分詞)
如果是不及物動詞 + 相應(yīng)的介詞或副詞
否定句式:be +not +done
疑問句式:be動詞(情態(tài)動詞)放句首
被動語態(tài)中的be為助動詞,無意義。be可能是am , is , are也可能是was ,were或原形be。
注:被動語態(tài)的時態(tài)是由be的時態(tài)決定的,be是什么時態(tài),全句就是什么時態(tài),be后面的過去分詞不變。
eg:
1.The song is liked by young people. (肯定句)
2.The song isn’t liked by young people.(否定句)
3. Is the song liked by young people ?(一般疑問句)
4.Who is the song liked by ?=By whom is the song liked?(特殊疑問句)
各種時態(tài)的構(gòu)成(動詞以do為例):
→一般現(xiàn)在時
動詞的被動形式:am/is /are done
例句:He is asked to do this.
→一般過去時
動詞的被動形式:was/were done
例句:The story was told by her mother.
→一般將來時
動詞的被動形式:will /shall be done
Is/are going to
例句:The problem will be discussed tomorrow.
→過去將來時
動詞的被動形式:should/would be done
Was/were are going to
例句:He said the trees would be planted soon.
→現(xiàn)在進行時
動詞的被動形式:am/is/are being done
例句:The novel is being written.
→過去進行時
動詞的被動形式:was/were being done
例句:At that time the desk was being made.
→現(xiàn)在完成時
動詞的被動形式:has/have been done
例句:The house has been built.
→過去完成時
動詞的被動形式:had been done
例句:They said that their work had been finished.
含有情態(tài)動詞的被動語態(tài):情態(tài)動詞+be+ done Your homework must be handed in today.
其它幾種特殊句型:
It is said that ……..
It is well known that …….
It is reported that……
例:
History is made by the people. (一般現(xiàn)在時)
The cars were made in Tianjin in 1995. (一般過去時)
The tree will be cut down next year.(一般將來時)
The room must be kept clean.(含有情態(tài)動詞的被動語態(tài))
The door is being opened.(現(xiàn)在進行時)
The film has been seen by me.(現(xiàn)在完成時)
注:不同時態(tài)的被動語態(tài)的差異主要體現(xiàn)在助動詞be的變化上,同時助動詞be還要在人稱和數(shù)上與主語保持一致。
