注:及物的短语动词相当于一个及物动词,可以有被动语态,这类短语动词有:turn on, turn off, find out ,laugh at ,look after, talk about, think of /about over, bring about, (引起;导至) put away, make out (认出),make up (编;补尝),look down upon,
pay attention to ,face up to (面对)
二、被动语态的用法
(1)动作的执行者不知道是谁或难以说明时常用被动语态。例如:
Street lights are often turned on at six in winter.
The new test book will be used next term.
(2)当动作的承受者比起动作的执行者来说更能引起人们的关心而需要加以强调时,要用被动语态。例如:
This kind of bicycle is not sold in our shop.
The thief was caught by a policeman yesterday.
(3)含有双宾语的句子,主动句中的间接宾语或者直接宾语都可变为被动语态中的一个主语,另一个保留不变。变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或for。
例如:The pianist gave the pupils some advice.
间接宾语 直接宾语
→The pupils were given some advice by the pianist.
