9、示主语是动作的执行者,被动语态表示主语是动作的承受者。做有关被动语态的题目可以分为两步走:第一步确定正确的时态,第二步确定正确的语态。判断用主动语态还是用被动语态的根据是看主语与谓语动词之间的关系:如果是主谓关系则用主动语态,如果是动宾关系则用被动语态。被动语态的构成(以write为例)时间 一般时态 进行时态 完成时态 现在 am/is/are written am/is/are being written has/have been written过去 was/were written was/were being written had been written将来 shall/will
10、be written 1.进行时、将来时、完成时、情态动词的被动语态的谓语分别是be being done,will/shall be done, have/has/had been done,情态动词be done,不要遗漏任何部分。All the work must be finished by Friday.A railway is being built to connect these two cities.2get过去分词表被动。They got married last week.He fell and got hurt.3主动形式表被动意义。(1)系动词look,feel,so
