19. We live day by day, but in the great things, the time of days and weeks ______ so small that a day is unimportant. A. is B. are C. has been D. have been 分析：A。句子主語為the time，故用謂語要用單數; 再根據句子前后的時態live和is，可知此處宜用一般現在時，不用現在完成時，故選A。 20. — ______ you ______ him around the museum yet? — Yes. We had a great time there. A. Have; shown B. Do; show C. Had; shown D. Did; show 分析：A。根據問句中的yet可知，所談論的事情發生在最近的過去，且問話者很關心這個過去發生的事情對現在的影響和結果，所以用現在完成時。注意：不要受答語中過去式謂語had的影響而誤選C。 21. —I have got a headache. —No wonder. You ______ in front of that computer too long. A. work B. are working C. have been working D. worked 分析：C。由于在電腦前工作太久，所以導致了現在頭痛的結果，故空格處應填現在完成時或現在完成進行時，即答案選C。 22. Professor James will give us a lecture on the Western culture, but when and where ______ yet. A. hasn’t been decided B. haven’t decided C. isn’t being decided D. aren’t decided 分析：A。根據句意，此處應用被動語態，不用主動語態; 再根據句末的yet可知，最好用現在完成時。故選A最佳。 23. So far this year we ______ a fall in house prices by between 5 and 10 percent. A. saw B. see C. had seen D. have seen 分析：D。短語so far意為“到目前為止”，它習慣上要與現在完成時連用。 24. —Do you think we should accept that offer? —Yes, we should, for we ______ such bad luck up till now, and time ______ out. A. have had; is running B. had; is running C. have; has been run D. have had; has been run 分析：A。根據句中的up till now可知，第一空應填現在完成時，故可排除B和C；run out的意思是“（時間）流逝”，為不及物動詞，以時間名詞作主語時，沒有被動語態，故可排除D。 25. —Have you known Dr. Jackson for a long time? —Yes, since she ______ the Chinese Society. A. has joined B. joins C. had joined D. joined 分析：D。since she join the Chinese Society為I have known Dr. Jackson since she join the Chinese Society之省略。連詞since所搭配的時態通常是：主句用現在完成時，從句用一般過去時。 上一頁 [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] 下一頁 引用地址: |
