Mad or not
Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built years ago, but for some reason it could not be used then. Last year, however, it came into use. Over a hundred people must have been driven away from their homes by the noise. I am one of the few people left. Sometimes I think this house will be knocked down by a passing plane. I have been offered a large sum of money to go away, but I am determined to stay here. Everybody says I must be mad and they are probably right.

被动语态的形成
时态 主动语态 被动语态(be+过去分词）
一般现在时 see / sees am(is,are)+seen
一般过去时 saw was(were)+seen
一般将来时 will (shall) +see will(shall)+be+seen
(过去将来时) would(should)+see would(should)+be+seen
现在进行时 am(is,are)+seeing am(is,are)+being+seen
(过去进行时) was(were)+seeing was(were)+being+seen
现在完成时 have(has)+seen have(has)+been+seen
(过去完成时) had+seen had+been+seen
含情态动词 情态动词+see 情态动词+be+seen
以see为例，比较主动语和态被动语态的结构形式
含情态动词的被动语态
1.含有情态动词(must, can, may, ought to, will/shall, could, would)的主动语态句子变成被动语态时，情态动词不作任何形式的改变：
You must write the letter in ink.你必须用钢笔写这封信°
The letter must be written in ink.这封信必须用钢笔写。
2.但半助动词像have to. be going to等要有數的变化：
We have to water the tree every day.我们每天都要给这棵树浇水。
The tree has to be watered every day.这棵树要每天浇水。
They are going to offer Tom a job.他们要给汤姆一份工作。
Tom is going to be offered a job.汤姆将得到- 份工作。
1.将主动语态的宾语改为被动语态的主语。
2.将主动语态的谓语动词改为“be+过去分词”结构。
3.将主动语态的主语改为介词by之后的宾语，
放在谓语动词之后（有时可省略）。
将下列句子改成被动语态。
2. People write business letters in English →
3.They make telephone calls in English. →
1.We use English as a foreign language. →
4.Travelers and business people use English. →
