哪些动词用作被动语态时,前面的be动词省略

Read,write, clean, wash, iron, burn, draw, cook, keep, cut, open, bolw, peel, sell, act等。

详解:这些词是由某些及物动词转化来的不及物动词,常和副词well, easily, smoothly等连用,且通常用主动结构表示被动含义。这些动词的主语一般是表物的词,且这些物往往具有某种内在的特点,这些句子的时态多用一般现在时或一般将来时,故可以省略be。

e.g This pen writes smoothly.

In hot weather meat won’t keep long.

The door can’t open.

The cloth washes well.

Clothes iron more easily when damp.

重点提示:

1)有些动词如:cook, print, do等,常常用主动结构的进行时表示被动含义。例如

The cakes are baking.

The lunch is cooking,

The book is printing.

Fish is selling briskly.( be在这里是系动词,不是被动语态的标志)

2)动词need, require, want, deserve, be worth后续v-ing的主动结构常表示被动含义:Who said the boy deserves punishing?(省略be)

3)某些系动词如feel, prove, smell, taste, sound等加上形容词,也可用主动语态表示被动意义:Your suggestion proved quite effective.

That smells delicious.(省略系动词be,smells相当于系动词)

4)有些以后缀-able或-ible结尾的形容词,例如:acceptable, available, drinkable, eatable, reliable, visible, punishable, feasible等,也可以表示被动意义:Your advice is not acceptable.(=not worth accepting)(be在这里是系动词,不是被动语态的标志)

5)某些介词短语,例如under discussion, under consideration, on display, on sale, under arrest, on trial, in dispute等,也可用主动结构表示被动含义:Some fresh vegetables have been on sale.(=been sold)

终于敲完了!!注意;我可是一字一词一标点给你敲上去的,绝对没有复制。还有什么疑问再发消息。以上文字中部分括号内的内容是我自己补充上去的,为的是便于你理解。
