答案：

1-2，被+过去分词

3如果主语是三单，句子是现在是，动词be变成is

4 用by连接动作的发出者，by也可以翻译成“被”

5 1】不是，这是完成时

2】在这里，by加一个时间，表示到这个时间为止，或者是在这个时间之前

6 1】是，be+being 加过去分词是被动语态的进行时，意思是“正在被”

2】这个by是“被某人某物”的意思，连接动作的发出者

7 被动语态的完成时的意思是“已经被”，构成是 have been加过去分词

8. 被动语态的完成时三单构成是把have been 加过去分词改为 has been加过去分词

9 被动语态的完成时非三单形式： have不变

10 被动语态完成时的否定式是：在have后加not

11 被动语态的过去完成时的构成 have变成had
