1. 连系动词look, taste, smell等后接形容词作表语，不用于被动语态，但汉语中有被动的意味。如：

Oh, the milk tastes strange - do you think it’s OK to drink?

4. 带双宾语的主动语态变为被动语态时，可将其中的一个变为被动句的主语，另一个不变。一般是把间接宾语变为被动语态的主语，如把直接宾语变为被动语态的主语，则在间接宾语前加介词for或者to。如：

My mother gave me a present on my tenth birthday.(主动语态)

I was given a present by my mother on my tenth birthday.

(被动语态，间接宾语作主语)

A present was given to me on my tenth birthday.

(被动语态，直接宾语作主语)

3. 主动句中使役动词make, let, have和感官动词see, feel, hear等后常接不带to的不定式，但在被动语态中，常将to还原出来。如：

The boss made the children work over twelve hours in the past.(主动语态)

The children were made to work over twelve hours (by the boss) in the past.(被动语态)

2. 通常只有及物动词才有被动语态，但一些不及物动词加上介词(副词)构成的动词短语也有被动语态，此时该动词短语不可分割，后面的介词(副词)不能省略。如：

(1) We heard a strange noise yesterday evening.(主动语态)

A strange noise was heard (by us) yesterday evening.

(被动语态，hear为及物动词)

(2) We put on a short play at the party last night.(主动语态)

A short play was put on at the party (by us) last night. (被动语态)

1. 分清动作的执行者和承受者，即分清主动语态和被动语态，如为被动语态，按照不同时态的被动语态规则进行变化。

10. to tell 　　　　　　　　　 11. (to) work　　　 　　　 12. to finish

7. listening　　　　　　　　　　 8. Doing　　 　　　　　 9. meeting

4. getting 　　　　　　　　　　 5. to get 　 　　　　　　6. giving

2. have sb. / sth. doing sth.意为“让某人/某物做某事”，动词-ing形式表示的动作往往具有持续、进行的含义。如：

The two men had their lights burning all night long. 那两个人让灯通宵亮着。

They tried to have her talking, but there was no use．他们尽力让她一直说话，但没用。

另： have sth. done 意为“把某事做好”。
