Passive Vice被动语态
一. 定义：被动语态是动词的一种特殊形式，用以说明主语和谓语动词之间的关系，表示主语是动作的承受者。一般情况下，只有需要动作对象的及物动词才有被动语态。
二. 构成：助动词be+及物动词的过去分词
... be (is/am/are) dne
... be (was/ were) dne
... will be dne
... be being dne
... verb (mdal) be dne
... have/ has been dne
... had been dne
... will have been dne
三. 主动语态到被动语态的转换
四. 主动语态变被动语态的注意事项
1. 时态保持一致例句:The teacher has punished him many times fr his lateness.He has been punished many times fr his lateness.
2. 谓语为动词短语的被动语态不能丢掉动词短语的介词或副词。例句：His best friend ften lks after him.He is ften lked after by his best friend.
3. 主动语态中若有双宾语，将其中一个宾语变为被动句的主语，另一个宾语不变。例句：Vivian gave me a bk.I was given a bk by Vivian.A bk was given t me by Vivian.
4. 主动语态若有复合宾语，将主动句的宾语变为被动句的主语，宾语补足语不变。例句：They call him Luis.He is called Luis.
5. 主动语态句中有make, have, let, ntice, see, watch, lk at等动词时，变成被动语态时，后面的不定式需要加上t。例句：Mr Lee made him wash the dishes.He was made t wash the dishes by Mr Lee.
