就这样讲英语。。。。。(16)

怎样把以下的(ACTIVE VOICE)主动语态句子变为被动语态(PASSIVE VOICE)？

1. The traffic accident happened here last night.

2. It rained heavily yesterday.

3. He swam with his friends in the pool.

4. That patient went to see the doctor but the doctor had no time to see him

5. This family lives in the rural area.

6. The plane disappeared shortly after taking off.

7. The baby slept soundly but the mother was not.

其实，上面的动词如 happen(happened), rain(rained), swim(swam), go(went), live(lives), disappear (disappeared) 和sleep (slept) 都是属于 自动词或不及物动词（intransitive verb）。

不及物动词（intransitive verb）是不可转变为被动语态(PASSIVE VOICE)。

如：

1. The traffic accident WAS HAPPENED here last night. （错）

2. It WAS RAINED heavily yesterday. （错）

3. He WAS SWUM with his friends in the pool. （错）

4. That patient WAS GONE to see the doctor but the doctor had no time to see him（错）

5. This family IS LIVED in the rural area. （错）

6. The plane WAS DISAPPEARED shortly after taking off. （错）

7. The baby WAS SLEPT soundly but the mother was not. （错）

为什么不及物动词（intransitive verb）不可转变为被动语态(PASSIVE VOICE)呢？那是因为不及物动词（intransitive verb）不须要宾语(OBJECT)，它可以成为完整的句子。反而及物动词（transitive verb）如就须宾语(OBJECT)才能是完整的句子。

例子

不及物动词（intransitive verb）

He came . （对）

He left. （对）

及物动词（transitive verb）

He ate. （不完整…….没有宾语(OBJECT)）

He ate an apple. （对）

He wrote. （不完整…….没有宾语(OBJECT) ）

He wrote a letter。（对）
