被動語態(tài)是由助動詞“be”+過去分詞構(gòu)成的.這里的“be”既要表示出與主語的人稱和數(shù)一致,也要表示出時、體的形式.被動語態(tài)有幾種特殊用法.每個人的情況不同，也可以登錄文都國際教育官網(wǎng)進行一對一的咨詢。

(1)主動形式表示被動意義

1)常見的這類動詞有：“act,add

up,clean,compare,count,cook,draw,fill,iron,keep,let,look,make

up,milk,kill,open,photograph,prove,read,sell,smoke,spoil”等.

The window won’t open.(這扇窗戶打不開.)

The cow milks well.(這頭牛出奶率很高.)

Damp wood will not fire.(濕木不易燃燒.)

She doesn’t photograph well.(她不上相.)

His judgment proved wrong.(他的判斷是錯的.)

It turned out fine that day.(結(jié)果那天天氣很好.)

How did his coat catch on a nail? (他的衣服怎么鉤到釘子上了?)

2)實用動詞“need/want/deserve/require +V-ing(動名詞)”形式表示被動意義.

My hair needs cutting..

The bike wants repairing.

There is nothing to worry about.

②不定式修飾want, have等動詞的賓語,而句中的主語同時又不是不定式的邏輯主語時：

I want some clothes to wash.

Do you have anything to say for yourself?

③不定式修飾buy,get,give等動詞的直接賓語,而句中的間接賓語又是不定式的邏輯主語時：

His sister gave him a bike to ride.

It is believed/thought that this medicine works well.

It is required(of)him that he give the evidence.(要求我提供證據(jù))

It is feared that he could not come here.

It is estimated that a flight to Shanghai would take more than one hour.

It is often realized that women held a high social position in the Southern European societies in the 10th and llth centuries.
