注:
(1)若句子中含有雙賓語,在改為被動語態(tài)時,遵循以下方法:
1.將間接賓語轉(zhuǎn)化為句子主語。
She gave the little girl some flowers.她給了那個小女孩一些花。
The little girl was given some flowers by her.
2.將直接賓語轉(zhuǎn)化為句子主語,此時間接賓語前通常加上介詞to或for(何時用to,何時用for,)。
例:They bought the children many good books.
他們給那些孩子買了許多好書。
→Many good books were bought for the children by them.
例:He lent me a pen.能借給我一支鋼筆?!鶤 pen was lent tome by him.
(2)在不定式作賓語補足語的結(jié)構(gòu)中,改為被動語態(tài)時,把主動語態(tài)中的賓語提到被動語態(tài)主語的位置,賓語補足語的位置不變。
例:He asked the boy to wash the car.他讓那個男孩洗車。
→The boy was asked to wash the car.
例:I saw a policeman enter the classroom.
我看見一名警察進(jìn)了教室。
→A policeman was seen to enter the classroom.
(3)不帶to的不定式作賓語補足語,在變?yōu)楸粍诱Z態(tài)時要加上to。
常接省略to的不定式作補足語的動詞有:
一感(feel)、二聽(listen to,hear)、三讓(let,make,have)、四看(watch,see,look at,notice),幫助(help)可帶可不帶。
