3. He kept looking at her, wondering whether he ______her somewhere.

A. saw                      B. has seen                C. sees                      D. had seen

分析：D。因?yàn)橛烧Z(yǔ)境可知，see應(yīng)當(dāng)發(fā)生在kept looking之前，即過(guò)去的過(guò)去，所以用過(guò)去完成時(shí)，只有D正確。又如：

When I had opened the windows I sat down and had a cup of tea. 我打開(kāi)窗戶后，就坐下來(lái)喝了一杯茶。

When I had written my letters I did some gardening. 我寫完信之后，就在花園里干了點(diǎn)活兒。

5. He ______more than 5000 English words when he entered the university at the age of 15.

A. has learned           B. would have learned C. learned                D. had learned

6. Father ______for London on business upon my arrival, so I didn’t see him.

A. has left                 B. left                       C. was leaving           D. had left

7. The policeman’s attention was suddenly caught by a small box which ______ placed under the Minister’s car.

A. has been               B. was being             C. had been               D. would be

11. The coffee is wonderful! It doesn’t taste like anything I ______ before.
