1. B. when引导的是一个非限制性定语从句，when指20世纪90年代初，当然用一般过去时。

2. A. 这是“祈使句+and +陈述句”句型，祈使句相当于一个条件状语从句，and后的陈述句的谓语用一般将来时，这是一个较为固定的句型。

3. D. 因为Jane已经度假去了，“离开”此地就当然是在此之前的过去某个时间了，所以用一般过去时，选D。另外，when通常都不与完成时连用，排除B和C，A也与语境不符。

4. D. 过去进行时在此表示过去准备要做的事。句意为：(Tony给我打电话时)我刚好做完工作，准备去冲凉。

5. A. 由now可知前句的意思是：我曾经叫你不要搬动我的词典的 (你偏不听)。“叫”是在过去发生的动作，用一般过去时。 6. C. 根据句意“我不知道Sam现在是否已经做完了作业，(但是我知道)他今天早上一直在做作业”，可知要用过去进行时。

7. B. 由What’s=What is可知，现在在出声音；进而知道“邻居们正在为一个晚会作准备”，所以用现在进行时态。再说，已经准备好了或者将作准备，我们不可能听得到声音，问句也就不成立了，排除A和D。

8. B. 根据but she hasn’t decided yet (尚未决定) 可知，从开始失业时起一直在考虑再去上学，现在还在考虑。表示从过去某一时刻开始一直到现在，并且现在依然在发生的动作，用现在完成进行时，现在完成进行时由“have/has been doing”构成，所以选B。 9. A. 由when the earthquake struck可知，要用一般过去时，排除C和D；又因为主语是单数the teacher，所以只有A正确。

10. D. 由when?was brought in可知，come也是过去发生的事，用一般过去时。句意是：当引入一个有趣的话题时，那场讨论又变得活跃起来。

11. C. 由all the T-shirts are sold at half price可知，这家商店还没有关闭，但准备将要关闭，所以选C，用现在进行时表示最近的打算。

12. A. “祈使句+or+陈述句”句型中，陈述句的谓语用“will+动词原形”，几乎是固定的。句意是：让我们扣住主题吧，否则，我们就作不了决定。

13. D. 因为was saying表明“他说”发生在过去，“没听到”应该是“他说”的时候没听到，所以miss也是发生在过去，而miss作“未听见、未理解”解时，一般没有进行时，因此，只有D正确。句意是：我的注意力当时并没有集中在他所说的内容上，所以恐怕有一半我都没听到。

14. D. 根据括号内的1847—1931可知，此处应填过去时态；另外，由于没有另一个过去的时间或动作与之比较，故不能用过去完成时，即只能选D。 15. A. 句意是：(你来我家时) 我正在机场等候一位从England来的朋友。表示在过去某一时刻或在过去某一段时间内正在发生的事，用过去进行时，所以选A。
