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。例:
This kind of cloth washes well.
My pen writes smoothly.
These books sell well.
2. 表示“发生、进行”等的不及物动词和短语, 如: happen, last, take place, break out, come out, come about, come true, run out等以主动形式表示被动意义。
例: How long did it last?
Great changes have taken place in Shanghai in the last few years.
I wish my dream would come true.
3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, smell, look等在主系表结构中常以主动形式表示被动意义。
例:Your reason sounds reasonable.
* 注意区分它们作
行为动词时可以被动:
An air of depression
was felt.
4. 在need,want,require等词的后面, 动名词用主动形式表示被动意义, 其含义相当于动词不定式的被动形式。
例: The house needs repairing.
to be repaired
5. 形容词worth后面跟动名词的主动形式表示被动含义,但不能跟动词不定式;而worthy后面跟动词不定式的被动形式。
例: The book is well
worth reading.
=The book is well
worthy to be read.)
6. 动词不定式在名词后面作定语,不定式和名词之间有动宾关系时,又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。
例: I have a lot of things to do this afternoon.(to do与things是动宾关系,与I 是主谓关系。)
试比较:I’ll go to the post office. Do you have a letter to be posted?
( 此处用不定式的被动语态作定语表明you不是post动作的执行者。)
7. 在某些“形容词+不定式”做表语或宾语补足语的结构中,句子的主语或宾语又是动词不定式的逻辑宾语时,这时常用不定式的主动形式表达被动意义。这些形容词有nice, easy, fit, hard, difficult, important, impossible, pleasant, interesting .例:
•English is easy to be learned.
•English is easy to learn.
•这道题很难解出.
This problem is difficult to work out
8. 在too… to…结构中,不定式前面可加逻辑主语,所以应用主动形式表示被动意义。例:
This book is too expensive (for me) to buy.
6. blame仍用不定式的主动形式表示被动意义。
Who is to blame for starting the fire?
The children were not to blame for the accident

提示:考虑建议盼原谅,承认推迟没得想。避免错过继续练,否认完成就欣赏。禁止想象才冒险,不禁介意准逃亡。
备注:不定式作定语,放在被修饰词后面,与前面被修饰的名词或代词有动宾关系,又在句子中与另一名词或代词有主谓关系,不定式要用主动表被动含义。
The book sells well.
The clothes wash easily.
