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