1. B. when引導的是一個非限制性定語從句，when指20世紀90年代初，當然用一般過去時。
2. A. 這是“祈使句+and +陳述句”句型，祈使句相當於一個條件狀語從句，and後的陳述句的'謂語用一般將來時，這是一個較為固定的句型。
3. D. 因為Jane已經度假去了，“離開”此地就當然是在此之前的過去某個時間了，所以用一般過去時，選D。另外，when通常都不與完成時連用，排除B和C，A也與語境不符。
4. D. 過去進行時在此表示過去準備要做的事。句意為：(Tony給我打電話時)我剛好做完工作，準備去沖涼。
5. A. 由now可知前句的意思是：我曾經叫你不要搬動我的詞典的 (你偏不聽)。“叫”是在過去發生的動作，用一般過去時。
6. C. 根據句意“我不知道Sam現在是否已經做完了作業，(但是我知道)他今天早上一直在做作業”，可知要用過去進行時。
7.B. 由What’s=What is可知，現在在出聲音;進而知道“鄰居們正在為一個晚會作準備”，所以用現在進行時態。再說，已經準備好了或者將作準備，我們不可能聽得到聲音，問句也就不成立了，排除A和D。
8. B. 根據but she hasn’t decided yet (尚未決定) 可知，從開始失業時起一直在考慮再去上學，現在還在考慮。表示從過去某一時刻開始一直到現在，並且現在依然在發生的動作，用現在完成進行時，現在完成進行時由“have/has been doing”構成，所以選B。
9. A. 由when the earthquake struck可知，要用一般過去時，排除C和D;又因為主語是單數the teacher，所以只有A正確。
10. D. 由when…was brought in可知，come也是過去發生的事，用一般過去時。句意是：當引入一個有趣的話題時，那場討論又變得活躍起來。
