英语主动改被动

1 The news was announced by the chairman
2 The island was said to be a good place for holiday.
3 A job will be offerd to me by him.
被动语态就是主语变宾语，宾语变主语，然后时态不改变，其他成分也不变。所以关键就是掌握句子的结构啦，分清主语，谓语，宾语都是什么，那样问题就迎刃而解了。

The news was announced by the chairman.
The island is said to be a good place for holiday.
A job will be offerredd to me by him.
有时改成被动句后，会省略掉BY后面得宾语了 成了A job will be offerredd to me 如第二句就不用说成
The island is said to be a good place for holiday BY THEM. 了
但有时后面不只是简单一个主格they she 什么的 而是像提供信息的
the chairman 就要说明了

1.The news was announced by the chairman .
2.It is said that the island is a good place for holiday.
3.A job will be offerd to me by him.

The news was announced by the chairman
The island was said to be a good place for holiday.
A job will offerd to me by him

1.The news be announced the chairman

我的绝对正确：
The news was announced by the chairman.
The island is said
