题目列表(包括答案和解析)
6.宾语起状语作用时。如:

1.宾语是反身代词时。如:

2.用法
一般过去时态的被动语态主要指在过去某一时刻或某一段时间内发生的动作。如:

所有这些东西都是我母亲昨天买的。
This kind of cup was used for drinking tea three hundred years ago.
三百年前这种茶杯是用来喝茶的。
主动变被动的特例
同学们都知道,只有带及物动词的句子才能由主动语态变成被动语态。但不是所有带宾语的动词都可以变成被动语态,请看下面几种不能变为被动语态的情况:
1.构成
由上表可知被动语态的一般过去式是was / were + 及物动词的过去分词构成。当主语是单数或不可数名词(代词)时,be用was;当主语是复数名词(代词)时,be用were。
3.其他
That’s very interesting. 那非常有趣。
Yes, many more. 是的,有许多。
When was the PLA founded? 中国人民解放军什么时候成立的? (被动语态)
It’s best to…
Thanks to…
What’s next?
The ground must be just right.
The hole should not be too deep.
教学建议
被动语态
本单元继续学习被动语态,我们已知道被动语态是由be + 过去分词构成。当不知道动作的执行者是谁或强调动作的承受者时,用被动语态。一般现在时的被动语态由is (am, are) + 过去分词构成,那么一般过去时态的被动语太就是was (were) 后加not。它的疑问形式一般是将was (were) 放在主语前。
构成:was / were + 及物动词的过去分词。
例如:The teaching building was built six years ago.
这座教学楼是八年前建的。
肯定句:The window was broken last night.
昨晚玻璃被打碎了。
否定句:The machine wasn’t used for cutting two years ago.
这机器两年前不是用来切东西的。
The paintings weren’t finished last year.
这些油画不是去年完成的。
一般疑问句:
Were the textbooks written in English in 1982?
这教材是在982年写的吗?
Yes, the were. / No, they weren’t.
是,是在1982年写的。/ 不,它们不是在1982年写的。
Was your school built in 1978?
你们学校是建于1978年吗?
Yes, it was. / No, it wasn’t.
是,它是1978年建的。/ 不,它不是1978年建的。
特殊疑问句:
When was this club founded?
俱乐部是什么时候成立的?
Where were those buses made?
这些汽车是在哪儿制造的?
[例]He saw here come out of the library.(改为被动语态)
误:She was seen come out of the library.
正:She was seen to come out of the library.
解析:凡主动语态的句子中有省去不定式符号to的不定式作宾语补足语,改为被动语态时,必须将不定式符号to加上,此时的不定式事实上是主语的补足语了。
被动语态的语法计时解
上一讲我们学了被动语态的一般现在时态概念、极成及其用法等。大家知道被动语态的结构是“be+及物动词的过去分词+其它”构成。被动语态的时态都是通过助动词be来体现的,即be是什么时态,该被动句就是什么时态。以动词do为例,就几种常见的时候列表如下:
时态 |
语态 |
一般现在时态 |
is / am / are don |
一般过去时态 |
was / were done |
一般将来时态 |
will be done |
本期我们将学习更多时态的被动语态,如一般过去时的被动语态:
2. 表示“有……”:
Are there any new inventions?
Is there any…?
