(这张桌子是被我爸爸制造的。) 注意:一般过去时的被动语态中be要变成过去时,第三人称单数和不可数名词做主语,谓语用was。其他情况下的主语,谓语用were。 该句中主语是单数table,为动作的承受者,所以be 动词用was;made 为make“制造”过去分词形式;句中由by引导的宾语father是被动句的执行者,说明这张桌子是爸爸制作的。 知识讲解(一般过去时被动句的形式) 肯定句:主语+was/were +及物动词的过去分词+其他成分 The table was made by my father. (这张桌子是被我爸爸制造的。) 否定句:主语+wasn't/weren't +及物动词的过去分词+其他成分 The table wasn't made by my father. (这张桌子不是被我爸爸制造的。) wasn't=was not weren't=were not 知识讲解(一般过去时被动句的形式) 一般疑问句:Was/Were +主语+及物动词的过去分词+其他成分? 肯定回答:Yes,主语+was/were. 否定回答:No,主语+wasn't/weren't Was the table made by your father ? Yes,it was./ No,it wasn't . 解析: 1.首先was/were 放于句首,需要大写; 2.陈述句中相应的人称在疑问句中要根据逻辑关系进行变化:该句中需要把原句的my father 变成your father; 3.不能照抄,需要审题。 知识讲解(一般过去时被动句的形式) 特殊疑问句:特殊疑问词+was/were +主语+及物动词 的过去分词+其他成分?
