yet.Ihave

already

beenintroducedtoMr.Smith.【注意】1)現(xiàn)在完成時被動語態(tài)的兩個助動詞：have／has和been缺一不可。2)注意與一般過去時被動語態(tài)的區(qū)別。

一般過去時被動語態(tài)表示一個被動的動作發(fā)生在過去，其結果對現(xiàn)在沒有影響；而現(xiàn)在完成時被動語態(tài)的動作或狀態(tài)盡管發(fā)生在過去，但側(cè)重說明該動作或狀態(tài)對現(xiàn)在造成的影響或結果。e.g.Themachinehasbeenrepaired．機器已經(jīng)修好了。(說明動作發(fā)生在過去，對現(xiàn)在有影響，修好了。)Themachinewasrepairedyesterday．機器昨天修了。(只說明動作發(fā)生在昨天。)3)動詞短語是一個不可分割的整體，在被動語態(tài)中要保持其完整性，其中的介詞或副詞不可省略。

e.g.Theorphanshavebeentakengoodcareofhere．孤兒們在這里受到很好的照顧。4)并不是所有動詞都有被動語態(tài)

happen,takeplace,breakout,belongto,cost,last等不及物動詞或詞組無被動語態(tài)。

[誤]GreatchangeshavebeentakenplaceinChinasince1978.[正]GreatchangeshavetakenplaceinChinasince1978.5)一些特殊動詞,如borrow,finish,begin,buy,start,return,marry,open,join等

構成的現(xiàn)在完成時的被動語態(tài)不能與表示一段時間的狀語連用。若要表達相應的意思，則需改換動詞或時態(tài)。如：Mybrotherhashad(不能用hasbought)thisbikeforalmostfouryears.Howlonghasthisbookbeenbought?Howlongagowasthisbookbought?6)只帶有一個賓語的動詞變?yōu)楸粍诱Z態(tài)時，將主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語。

e.g.Wehavebuiltmanyhousesinthepasttenyears.→Manyhouseshavebeenbuiltinthepasttenyears.7)帶有雙賓語的動詞，如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,tell,pay,lend,pass,promise等，變?yōu)楸粍诱Z態(tài)時，可將其中一個賓語變?yōu)橹髡Z，另一個保留不動。

e.g.Wehavegivenhimthebook.→He

hasbeengiventhebook.→Thebookhasbeengiventohim.8)帶有復合賓語的動詞變?yōu)楸粍诱Z態(tài)時，只能將賓語變?yōu)橹髡Z，原來的賓補改為主語補足語。原來省略to的不定式作賓補的，被動語態(tài)中要用帶to的不定式。

e.g.Ihavetoldthemtohelpyou.→Theyhavebeentold

tohelpyou.Ihavemadeherworkhard.→Shehasbeenmadetoworkhard.用所給（短語）動詞的正確形式填空。1.Thechildren_______________(tell)manytimesnottogoneartheriver.2.Inthelastfewyearsthousandsoffilms_________________(produce)allovertheworld.
