答案:

1. A。句子是有关美语中的一个语法现象的，是经常性的状态，且这个音节是人为漏掉的，所以用一般　现在时的被动语态。

2. D。实验（experiments）和动词conduct（实施）是被动关系，而且是在“before the Second 　World War”进行的，即“过去的过去”，所以选D。

3. D。give接双宾语，“他”应被给一些建议，排除A、C；“他”听从建议，是主动关系，所以选D。

4. A。句意：这个沿海地区去年被命名为国家级野生动物保护区。

5. B。in the last three years 在过去三年里，一般与现在完成时连用，“建筑物”与“set up”是　动宾关系，所以用B。

6. A。by the end of last month 到上个月末为止，一般要用过去完成时；“They”是“finish”的　执行者，所以选A。

7. A。take place 发生，不能用被动语态；“school”是“被开设（open）”的，而且现在已经有了　变化，要用现在完成时表示过去的动作对现在的结果，因此选A。

8. D。桥现在不能使用，应该是正在被修理。

9. A。警察给“我”指路，“我”与“指路”是被动关系。

10. A。break out 爆发，是不可数名词，不用被动语态；过去某时发生的事，要用一般过去时。

11. A。“水”是人加热的，所以是被动语态。

12. C。门是被锁的，用被动语态。注意lock也有不及物动词的用法，表示主语的特征，不用被动语态，如：The door won’t lock. 这个门锁不上。

13. B。make sb. do sth. 使某人做某事，变成被动句后要把do前省略的to加上。They与动词work是主动的，因此要用不定式的主动式。

14. C。句意：许多国家都发射了人造卫星。根据句意应用现在完成时，卫星是被发射的，因此用C。

15. B。found 动词（原形），意为“建立”，过去式、过去分词是founded。
