2.某些谓语动词的主动形式表示被动意义语法互动(十) 时态和语态to work(1)英语中有很多动词,如: break, catch, clean, drive, lock, open, sell, read, write, wash等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表达被动意义,主语通常是物。如:
This kind of cloth ______________.
这种布料很好洗。
[注意] 主动语态表被动强调的是主语的特征,而被动语态则强调外界作用造成的影响。
试比较:

语法互动(十) 时态和语态Your reason sounds reasonable.
你的理由听起来很合理。
(4)下列结构中的v.-ing必须用主动形式表示被动意义:
①want(need, require, request)“需要”+v.-ing。但当这些动词后接不定式时,则必须用被动形式表示被动意义。如:
The bike needs mending.这辆自行车需要修理。
Our classroom needs to be cleaned.
我们的教室需要打扫。
②be worth doing sth值得做某事 如:

2.某些谓语动词的主动形式表示被动意义语法互动(十) 时态和语态to work(1)英语中有很多动词,如: break, catch, clean, drive, lock, open, sell, read, write, wash等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表达被动意义,主语通常是物。如:
This kind of cloth ______________.
这种布料很好洗。
[注意] 主动语态表被动强调的是主语的特征,而被动语态则强调外界作用造成的影响。
试比较:
The door won't lock.(指门本身有毛病)语法互动(十) 时态和语态washes well The door won't be locked.(指不会有人来锁门,表示“门没有锁”是人的原因)

语法互动(十) 时态和语态Your reason sounds reasonable.
你的理由听起来很合理。
(4)下列结构中的v.-ing必须用主动形式表示被动意义:
①want(need, require, request)“需要”+v.-ing。但当这些动词后接不定式时,则必须用被动形式表示被动意义。如:
