主动句变被动句之欧阳文创编

1、主动句变被动句时间：2021.03.12创作：欧阳文被动语态由“be+done”构成。不同时态的被动语态的差异主要 体现在助动词be的变化上，同时be还要在人称和数上与主语保持一 致。在将主动语态变为被动语态时，可按以下三个步骤:a. 把主动语态的宾语变为被动语态的主语。b. 把谓语变成被动结构（be + done）,并根据被动语态句子里 的主语的人称和数以及原来主动语态句子中动词的时态来 决定be的形式。c. 把主动语态中的主语放在介词by Z后作宾语，将主格改为 宾格。在无须说明动作的执行者或只强调动作的承受者 时，by短语可以省略。例如：1. We speak Chinese. Chin

2、ese is spoken by us.2. All the people laughed at him. He was laughed at byall people.3. They make the bikes in the factory. The bikes are made by them in the factory.含有双宾语的主动句改为被动句时，应将其屮一个宾语改为被动结 构的主语，另一个宾语仍保留在原处。一种情况是把间接宾语（指人） 变为主语，直接宾语（指物）不变；另一种情况是把直接宾语（指物）变 欧阳文创编为主语，间接宾语（指人）不变，这时，间接宾语前通常加介词to,有时加

I was given a new book (by my father) on my birthday.(间接宾语作了主语)A new book was given to me (by my fat her) on mybirthday.（直接宾语作了主语）常跟双宾语的动词有：give sb. sth. / givesth.tosb.show sb. sth. / show sth. to sbsend sb. sth. / send sth. to sb.bring sb. sth
