Grammar The passive voice ☆被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be后面的过去分词不变。 时态 主语 单数 复数 过去分词 一般现在时 The car/cars is are designed. 一般过去时 The car/cars was were designed. 现在完成时 The car/cars has been have been designed. 过去完成时 The car/cars had been had been designed. 一般将来时 The car/cars will be will be designed. 将来完成时 The car/cars will have been will have been designed. 现在进行时 The car/cars is being are being designed. 过去进行时 The car/cars was being were being designed. 一般将来时被动语态用法: 1) 一般将来时被动语态由 “shall(will)+be+及物动词的过去分词”构成。使用时应注意下面句型由主动语态变为被动语态的方法。 (1)  主语+谓语+宾语，例如： 主动:We’ll build a new house next year. 被动:A new house will be built(by us) next year. (2) 主语+谓语+间接宾语+直接宾语(习惯上把间接宾语变为被动语态的主语) 主动: My mother will give me a shirt. 被动: I will be given a shirt (by my mother). 如果把直接宾语改为主语时, 则在间接宾语前加to或for 主动: My mother will give me a shirt. 被动: A new shirt will be given to me (by my mother).
