动作由主语去承受，那么就用被动语态，此时主语与动作之间在逻辑上具有动宾关系。
1.英语中有两种语态：主动语态和被动语态。
2.主动语态表示主语是动作的执行者，例如：Many people speak Chinese.
3.被动语态表示主语是动作的承受者例如：上句可变为Chinese is spoken by many people.
4.英语的被动语态由“助动词be+过去分词”构成，其中be有时态、人称和数的变化。
1.被动语态的概念
各种时态的被动语态 被动语态的构成 be 过去分词
1 一般现在时的被动语态 am /is / are 过去分词
2 一般过去时的被动语态 was /were 过去分词
3 现在进行时的被动语态 am / is / are +being 过去分词
4 过去进行时的被动语态 was /were +being 过去分词
5 现在完成时的被动语态 have / has been 过去分词
6 过去完成时的被动语态 had been 过去分词
7 将来完成时的被动语态 will / shall have been 过去分词
8 一般将来时的被动语态 will / shall be 过去分词
9 过去将来时的被动语态 would / should be 过去分词
2. 九种时态的被动语态
1.We are given a lot of homework to do.我们有很多作业要做。
2.They were given a warm send-off.他们受到热烈的欢送。
3.I think we are being followed.我想有人在跟踪我们。
4.They told me that the case was being investigated.他们告诉我案子正在调查。
5.The documents for which they were searching have been recovered.他们找寻的文件己找到了。

7.Check carefully, so any mistakes will be caught.仔细检查一遍，把所有错误都找出来。
8.He knew he would be punished for it.他知道他会为此受到惩罚。
请看以下例句：
3.含有情态动词的被动语态
1.You might be asked to speak at the meeting.可能请你在会上发言。
2.Whenever (they are)known, such facts should be reported.这类情况一旦发现就要报告。
3.All the above items can be obtained from our office.所有上述资料可向我们办公室索取。
4.Something must be done to stop these accidents.必须采取某种措施以防止这些事故。
5.These books may be appreciated better by older children.年龄稍大的孩子可能更会欣赏这些书。
3. 含有情态动词的被动语态由“情态动词+be+过去分词”构成。
4.短语动词的被动语态
1.Good use is made of the library.这图书馆的利用率很高。
2.A man who is much talked about is always very attractive.被人谈论多的人经常是很有吸引力的人。
3.Many interesting experiments are carried out in our laboratory.我们实验室做了许多有趣的实验。
“动词+介词或副词”构成的短语动词，以及“动词+名词+介词”构成的短语动词，在被动语态中不要漏掉后面的介词或副词。如：
5.关于“get+过去分词”
。如：I got dressed as quickly as 1 could.我尽快穿上衣服。I wasn't surprised she get elected after all the efforts she made.她尽了一切力量之后，当选了，这不使我感到奇怪。
在英语口语中，有时可用“get+过去分词”构成被动语态

2. A railway is being built in our hometown.
3. Listen! The piano is being played by someone upstairs.
4. The car is being washed right now.

区分“状态”与“动作”：
有些动词的过去分词可以作形容词，表示一种状态，而不是正在进行的动作。
现在进行时的被动语态的注意事项
take care of, look after, talk about , think of, carry out等动词短语用于现在进行时的被动语态时,其中的介词或副词不可省略。

What else is being thought of
现在进行时的被动语态的注意事项
不及物动词(短语)非持续性动词表示存在意义/所属关系/静态特征的动词以及系动词不用于现在进行时的被动语态。
只有及物动词（后面可以接宾语的动词）才有被动语态。不及物动词（如 happen, appear, die）没有被动形式。

The book belongs to him.
The book is being belonged to him.
没有进行时被动语态
