9. I ______ you not to move my dictionary—-now I can’t find it.

A. asked                   B. ask                       C. was asking            D. had asked

解析：答案選 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。

10. The teacher, with 6 girls and 8 boys of her class, ______ visiting a museum when the earthquake struck.

A. was                      B. were                     C. had been               D. would be

解析：答案選 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。

11. The discussion ____ alive when an interesting topic was brought in.

A. was coming          B. had come              C. has come              D. came

解析：答案選 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。

12. She ______her hairstyle in her hometown before she came to Chongqing for a better job.

A. would change        B. has changed          C. changed                D. was changing

解析：答案選 C。由came可知，她已來重慶了，而改變發型是在來重慶之前，即過去的過去，按理要用過去完成時，但before已經表明緊接著發生的先后兩個動作，所以也可用一般過去時，所以選C。

13. What we used to think ______ impossible now does seem possible.

A. is                         B. was                      C. has been               D. will be

解析：答案選 B。根據句中的used to可知，空格處應填一般過去時。句意為：我們過去認為不可能的現在都似乎有可能成為現實。

14. It is said that the early European playing-cards ______ for entertainment and education.

A. were being designed                              B. have designed       

C. have been designed                               D. were designed

解析：答案選 D。解答此題的關鍵是要抓住early這一形容詞。early European playing-cards的意思是“早期歐洲人玩的撲克牌”，既然是“早期”，肯定就是過去的事了，所以用一般過去時。

15. I ______ in London for many years, but I’ve never regretted my final decision to move back to China.(www.cpsenglish.com)

A. lived                    B. was living　 C. have lived                     D. had lived

解析：答案選 A。許多同學一看到后面的have never regretted為現在完成時，同時選項C也是現在完成時，結果濫用時態呼應，將答案誤選C。其實，此題的最佳答案是A。句中but后的句子告訴我們，說話者現在已搬回了上海，所以他住在倫敦應屬于過去的事情，故應用一般過去時。

16. Eliza remembers everything exactly as if ______ yesterday.

A. was happening      B. happens                C. has happened        D. happened

解析：答案選 D。根據句中的yesterday可知，要用一般過去時。
