(2)将动词改为"be+过去分词"。 They held a meeting yesterday. → A meeting was held by them yesterday. (3)将主动语态的主语改为be…放在谓语动词后。 注意：如果原主语是代词，则应由主格变为宾格。 He sang a song. → A song was sung by him. 主动语态变为被动语态 (1)主动句中的主语如果是people, we, you, they, somebody等含糊地表示"人们"、"大家"的单词，变为主动句时，通常删去"by…"，但原主语被强调者除外。如： They set up this hospital in 1975. → This hospital was set up in 1975. Only he can finish the job. → The job can be finished only by him. 主动语态变为被动语态的注意事项 (2)含有双宾语，即直接宾语和间接宾语的句子，每个宾语都可变为被动语态的主语，即其被动语态有两种形式。但多以间接宾语作主语。 Jack told us the truth.杰克告诉了我们真相。 We were told the truth by Jack.
