2020年中考英語知識點之被動語態(tài)的結(jié)構(gòu)與應用情況(2)

　　→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：

　�、貶istory is made by the people. (一般現(xiàn)在時)

　�、赥he cars were made in Tianjin in 1995. (一般過去時)

　�、跿he tree will be cut down next year.(一般將來時)

　�、躎he room must be kept clean.（含有情態(tài)動詞的被動語態(tài)）

　�、軹he door is being opened.（現(xiàn)在進行時）

　　⑥The 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。

　�、蹜�用情況

　　行為的執(zhí)行者不明確或不必說出來。

　　Eg:  A stranger was killed  last night.

　　用于強調(diào)動作的承受者而不是執(zhí)行者。

　　Eg: The story is told everywhere in the city.
