Grammar Focus
英语有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,而被动语态则表示主语是动作的承受者。
e.g. We cleaned the classroom yesterday.
(主动语态,主语we是clean这一动作的执行者)
The classroom was cleaned yesterday.
(被动语态,主语the classroom是clean这一动作的承受者)
Grammar Focus
一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词(+by+动作的执行者).”。如:
Trees were planted last spring.
去年春天种了树。
一、一般过去时被动语态
Grammar Focus
1. 肯定句:
主语+was / were+及物动词的过去分词+其他.
e.g. Paper was invented by Chinese people two thousand years ago.
纸是中国人在二千多年前发明的。
Grammar Focus
2. 否定句:
主语+ was/were not+及物动词的过
去分词+其他.
e.g. Women were not allowed to take part in the games at first.
开始妇女不允许参加奥运会。
Grammar Focus
e.g. Was this picture drawn by your sister
这幅画是你妹妹画的吗?
3. 一般疑问句:
Was/Were +主语 +及物动词的过去分
词+其他
Grammar Focus
1. 不知道谁是动作的执行者,或没有必要指出谁是动作的执行者。
e.g. English is spoken all over the world.
全世界都在说英语。
2. 需要突出或强调动作的承受者。
e.g. This dictionary is used by most students.
这本字典是大多数学生在用的。
二、被动语态的用法:
Grammar Focus
1. 有些短语动词相当于及物动词,变为被动句时介词或副词不能去掉。
e.g. They put off the meeting because of the weather.
→ The meeting was put off because of the weather.
会议因天气的缘故被推迟了。
三、主动语态变被动语态应注意的问题
Grammar Focus
2. 含有双宾语的主动句变为被动句时,通常把指“人”的间接宾语变为主语,指“物”的直接宾语保留不变;如果把指“物”的直接宾语变为主语,则在间接语前加to或for。
e.g. My aunt gave me an e-dictionary yesterday.
I was given an e-dictionary yesterday.
An e-dictionary was given to me
yesterday.
Grammar Focus
3. 主动句中感官动词see / hear / watch / feel等和使役动词make / let / have等后跟省略to的动词不定式,变为被动语态时应加上不定式标志to。
e.g. I saw a heavy man enter the house.
A heavy man was seen to enter the house.
Grammar Focus
4. 系动词、不及物动词或某些短语动词(happen, take place, come true, fall asleep…)没有被动语态。
