例3:Whohasbeeninvented?

陈述句主语+has/havebeen(not)+P.P.+...例1:Hermotorbikehasbeenstolen.
一般疑问句Has/have+主语+been+P.P.+...?特殊疑问句特殊疑问词+have/has+been+P.P.+...?构成①由finish,buy,start,begin,post,return,borrow,marry,open等词构成的现在完成时的被动语态,不能与表示段时间的状语,如forfourdays,howlong等连用,而要改换动词或者是时态。
注意事项判断正误:*Howlonghasthisbookbeenbought?()
*Howlongagowasthisbookbought?
()XV②短语动词不能分割,而且不能省略短语动词中的介词或副词。
注意事项判断正误:*Thepatienthasbeentakengood
care.
()*Thepatienthasbeentakengood
careof.()XV③并不是所有的动词都有被动语态。如happen,occur,
takeplace,breakout,belongto,cost,last等不及物动词或词组,就没有被动语态。
注意事项判断正误:*Someofthebestconversationshaveeverhappenedaroundthedinnertable.()*Someofthebestconversationshappenedaroundthedinnertable.()VX④双宾语动词变被动语态可将其中的一个宾语变为主语,另一个保留不动。
注意事项主动:Ihavegivenhimthekey.被动:He
hasbeengiven
thekey.被动:Thekey
hasbeengiven
(to)him.⑤带复合宾语的动词变被动语态时,只能将宾语变为主语,原来的宾补保留不动,改成主语补足语。
注意事项
主动:Ihaveaskedhertohelpyou.被动:She
hasbeenasked
tohelpyou.主动语态中作宾语补足语的不带to的不定式变为被动时,要加上to。例:Theengineermadetherobotcleanthewindowsofthetallbuilding.
