现在完成时的被动语态
含情态动词的被动语态
语法精讲
一、被动语态的概念
语态是动词的一种形式，表示主语和谓语动词之间的关系， 英语语态分为主动语态和被动语态两种。主动语态表示主语是谓语动作的执行者，被动语态表示主语是谓语动作的承受者。
三、被动语态的用法
1.不知道或没必要指出动作的执行者。
2. 强调动作的承受者。
3. 出于策略、婉转、礼貌等不提出动作的执行者。
As he was not allowed to accompany her...
She was being offered sympathy by a robot.
A robot is offering sympathy to her.
He has been warned of this twice.
四、使用被动语态时应注意的问题
1.不及物动词, 不及物动词短语或系动词没有被动语态。常见的有：appear, disappear, break out, come true, run out, date back to, happen, go on, take place, belong to,等。
2.在主动语态中，动词see, hear, make, watch, notice等后面作宾语补足语的不定式不带to, 但变为被动态时，to 必须补上。
They made him go there alone.
He was made (go) there alone.
Great changes ________ ( take place）in my hometown in the last ten years.
have taken place
to go
注意！
1. 主动句的谓语动词带有复合宾语时，应将宾语变成被动句的主语，宾语补足语不变
Eg: We saw him sitting there without doing anything.
→ He was seen sitting there without doing anything.
我们看见他坐在那儿什么也没做。
小试牛刀：
We heard her singing in the classroom.
→
She was heard singing in the classroom.
在主动态中make,hear,see,等词后接不定式省略to，但转换为被动语态时不能省略to.
eg: His words made me throw up. 他的话让我想吐。
→ I was made to throw up by his words.
注意！
2. 带双宾的动词转换为被动语态时，可将表示物的直接宾语变为主语，用for/to引出表示人的间接宾语，或表示人的间接宾语变为主语
Eg: My father is telling me an interesting story now.
→ An interesting story is being told to me by my father now.
父亲正在给我讲一个有趣的故事
小试牛刀：
My mother bought me a toy.
→
A toy was bought for me.
什么时候使用被动语态？
Sugar cane is grown in the south.
The song The East is Red was written by a poor peasant.
1. 不知道或没必要指出动作的执行者。
2. 强调动作的承受者。
(1) We saw him sitting there without doing anything.
→ He ________________ there without doing anything.
was seen sitting
被动语态的常见考点
1．当动词后有复合宾语(宾语+ 宾补)，变被动语态时，
将宾语变为被动结构中的主语即可，其它不变。
e.g. The police caught the thief stealing.
→ The thief was caught stealing.
My father is telling me an interesting story now.
→ An interesting story ___________________ by my
father now.
→I ________________an interesting story by my father now.
is being told to me
am being told
2．主动变为被动时, 双宾语的变化。
可将表示物的(直接)宾语变为主语, 用for或to引出人;
或将表示人的(间接)宾语变为主语。
被动语态
语态是动词的一种形式，用来说明主语和谓语动词之间的关系。英语动词有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
使用被动语态的句子，谓语动词的形式是“be +动词过去分
词”。语义上主语为动作的承受者或对象，主要用于需要强调动作承受者、不必要指出动作执行者的情况，或出于语篇衔接连贯在“be +动词过去分词”结构中，助动词be有时态、人称和数的变化，变化规则与系动词be相同。
2．在这个城市里，机器人随处可见，人们以一种快节奏忙碌地工作着。
(一般表达)In this city, robots were easy to see everywhere and people were working busily at a rapid pace.
(高级表达)_________________________________________________


In this city where robots were easy to see everywhere, people were working busily at a rapid pace.
