哪些动词用作被动语态时,前面的be动词省略
1个回答
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）
