三 被动语态的注意事项
1 “主语+系动词+表语”的句子没有被动语
态
2 there be 句型没有被动语态
3 主动句中宾语是反身代词的没有被动语态
4 主动句的谓语动词是不及物动词的没有
被动语态，但与介词搭配后，则有:

• Practice:
1 Must I pay for it at once? _M__us_t_ it _b_e_e_n _p_a_id__ __f_or__ at once?
2 We will build a new lab. A new lab _w_i_ll_ _b_e__ _b_u_i_lt_.
英语动词有两种语态：主动语态和被动语态。 1.当我们不知道谁是动作的执行者, 2. 或者只需强调动作的承受者时，要用被动语态。
被动语态结构：主 +be + 过去分词(PP) + (by …)
在改写中应注意：
1.把原来的宾语提到前面作被动语态的主语;
2.把动词变成“be + 过去分词”;
3.主动语态中的主语变为介词by的宾语。
