The Passive voice 动词被动语态 : be + 过去分词 （ 及物动词 ） 被动语态是英语动词的一种特殊形式. 汉语中往往用 “ 被 ” “ 受 ” “ 给 ” 等词来表示被动意义. 主动语态变为被动语态的方法 : 1. 主动句中的宾语变成被动句的主语. 2. 主动句中的谓语动词变成被动句的 be + 过去分词. 3. 主动句中的主语变成被动句 by 的宾语, 放在谓语动词 后面. 如果不强调动作执行者时, by 短语可省略. Many people speak English. English is spoken by many people.

The song is often sung by children. 一般过去时 ( The Past Indefinite Tense ) was, were + 过去分词 A PLA man saved him. He was saved by a PLA man. 一般将来时 ( The Future Indefinite Tense ) will be, shall be + 过去分词 They will take her to the hospital. She will be taken to the hospital.

The Passive voice 主动语态变成被动语态时要注意以下几点 : 1. 含有双宾语的主动句变成被动句时, 可以将其中一个 宾语变为主语, 另一个不动. 一般把间接宾语变为主语. 如 : Mary gave me a pen. I was given a pen by Mary. 如果把直接宾语变为主语, 则在间接宾语前加 “ to ” 如 : A pen was given to me by Mary. 2. 含有复合宾语的主动句变为被动句时, 将其中的宾语变 为主语, 宾补不变. 如 : We asked him to speak at the meeting. He was asked to speak at the meeting.

3. 如果主动句中的谓语是短语动词, 变为被动句 时, 短语动词的介词或副词不可以丢掉. 如 : They took good care of the boys. The boys were taken good care of. 4. 在 “ let, make, see, hear, notice, watch, feel ” 等动词后面做宾语补足语的动词不定式不带 “ to ”, 但改成被动句时应加上 “ to ”. 如 : The doctor made me stay in bed for three days. I was made to stay in bed for three days by the doctor.
