主动句变被动句
解题思路： 你可以把答案通过讨论发过来
解题过程：
一、主动语态和被动语态概说
英语的语态分主动语态和被动语态，主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。被动语态由“助动词be+过去分词”构成：
Everybody likes him. 大家都喜欢他。 (主动语态)
He is liked by everybody. 他受到大家的喜欢。(被动语态)
二、主动语态变被动语态的方法
1. 主动语态变被动语态的基本方法
将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)：
He broke the cup. → The cup was broken by him.
【注意】若不强调动词执行者，被动语态中的by短语通常可以省略：
He was born in 1986. 他生于1986年。
What is this flower called? 这种花叫什么花?
2. 被动语态的时态
被动语态的时态由被动结构“be+过去分词”中的动词be来体现，其基本结构和用法如下：
(1) 一般现在时的被动语态：am [is, are]+过去分词
English is taught in our school. 我们学校学英语。
We are taken good care of at school. 我们在学校受到很好的照顾。
(2) 一般过去时的被动语态：was [were]+过去分词
He was taken to the police station. 他被带到了警察局。
The house was built ten years ago. 这座房子是10年前建的。
(3) 一般将来时的被动语态：will be+过去分词
A new building will be built here soon. 不久这里将建一栋新楼。
The meeting will be held at two this afternoon. 会议将于今天下午2点举行。
(4) 现在完成时的被动语态：have [has]been+过去分词
All the work has been done now. 所有的工作现在都做好了。
Have the letters been posted? 信都寄了吗?
(5) 过去完成时的被动语态：had been+过去分词
He said the work had been finished. 他说工作已完成了。
(6) 现在进行时的被动语态：am [is, are] being+过去分词
My watch is being repaired by him. 我的表正在由他修理。
The plan is now being discussed. 计划现在正在讨论。
(7) 过去进行时的被动语态：was [were] being+过去分词
He said that the man was being operated on. 他说那个人正在动手术。
He told me that a new station was being built. 他说正在修建一个新车站。
(8) 过去将来时的被动语态：would be+过去分词
He said that the meeting would be held next week. 他说会议将于下周举于。
3. 含有情态动词的被动形式
若主动语态中谓语含有情态动词，在相应的被动语态中通常应保留该情态动词，其结构为“情态动词+be+过去分词”：
Everyone must know this. →This must be known by everyone.
请看以下带情态动词被动句实例：
This can’t be done in a short time. 这不是短期内可以完成的。
Can this be done by machine? 这可以由机器来做吗?
The work must be done at once. 这工作必须马上做了。
