动词短语构成的被动语态应注意的个问题
一般情况下，只有及物动词才能跟宾语，而不及物动词不能跟宾语，所以只有及物动词才有被动语态，不及物动词则没有被动语态。但有些不及物动词后面跟上介词或副词后，变成一个动词短语，相当于一个及物动词，因此就可以有被动语态。
The nurses in this hospital look after the patients very well.
-- The patients are well looked after by the nurses in this hospital. 病人在这所医院里被护士们照料得很周到。
They have put off the meeting till next Saturday.
-- The meeting has been put off till next Saturday. 会议已推迟到下周六了。
注意：
在初中英语语法练习题使用被动语态时，千万不要遗漏句末的介词或副词。
Such a bad habit should be got rid of. 这样的坏习惯应该改掉。
All the important matters have now been attended to. 所有重要的事情都得到了处理。
双重被动结构
双重被动结构指的是句中谓语动词和其后的不定式均为被动结构，句子的主语既是谓语动词的承受者，同时又是不定式动作的承受者。
They asked us to discuss the problem at once.
-- We were asked to discuss the problem at once.
-- The problem was asked to be discussed at once. 这个问题被要求立刻讨论。（双重被动）
She offered to buy a recorder for me.
-- A recorder was offered to be bought for me. 有人提出要帮我买一台录音机。（双重被动）
The teacher ordered that we should take the desk away.
-- The desk was ordered to be taken away. 课桌被要求搬走。（双重被动）
下列句子变成被动语态时，要用with，不用by
Smoke filled the meeting room. 烟充满了会议室。
The meeting room was filled with smoke. 会议室里充满了烟。
A cloth covered the table. 一块布把桌子罩了起来。
The table was covered with a cloth. 桌子上铺着一块布。
