1．除及物动词外，一些相当于及物动词的短语动词也可使用被动态形式，除个别情况。
短语动词一般不拆开使用。例如：
This matter will be dealt with as soon as possible.
2．不及物动词（或相当于一个不及物动词的短语动词）和表示状态的动词（或短语动词）无被动语态形式，如：happen, rise, occur, take place, break out 等；以及lack, fit suit，equal, become, resemble, befall, consist of, look like等。例如：
The story took place in 1949.
3．将主动态形式改为被动态形式时，如遇到动词后跟双宾语的情况，我们只能将其中之一变成主语，另一个保持不变。当直接宾语变成主语时，保持在原位的间接宾语前需加介词to。例如:
I gave my husband a tie as a birthday present.
→My husband was given a tie as a birthday present.
→A tie was given to my husband as a birthday present.
4．不定式符号to在被动语态中不可省略。在主动语态中，感官动词和“使”动词常跟不带“to”的动词不定式，但在被动词态中要有“to”。例如：
I saw her pass by the window. She was seen to pass by the window.
