(5)带有双宾语的动词,如give,send,bring,take,teach,show,tell,make, sing,write,read,sell,buy,pay,lend,pass等,变为被动语态时,可将其 中一个宾语变为主语,另一个保留不动。 We have given him the book. →He has been given the book. →The book has been given to him.

4.现在完成时的被动语态应注意的几个问题 (1)现在完成时的被动语态与一般过去时的被动语态的区别。 一般过去时的被动语态所表示的动作或状态与现在的情况没有联系,而现在完 成时的被动语态则强调与现在的情况有联系。 The bridge was built last year.这座桥是去年建成的。 The bridge has been built.这座桥已经建好了。 (2) 含 有 非 延 续 性 动 词 , 如 : borrow , finish , begin , buy , start , return , marry,open,join等的现在完成时的被动语态的肯定式不能与表示一段时间 的状语连用。若要表达相应的意思,则须改换动词或时态。 这本书买了多长时间了?
运用现在完成时的被动语态时应掌握以下几个问题: 1.构成 现在完成时的被动语态的构成为:have/has been+过去分词。
2.各种句式
肯定式
主语+have/has been done...
பைடு நூலகம்
否定式
主语+have/has not been done...
一般疑问式
