A. was having B. have C. have ever had D. had ever had
分析：C。與before連用，用現在完成時。再說，此處沒有一個過去時間或動作比較，是不能用過去完成時的。
10. My brother is an actor. He ______in several film so far.
A. appears B. appeared C. has appeared D. is appearing
分析：C。因so far(到目前為止)通常與現在完成時連用。
11. The country life he was used to ______ greatly since 1992.
A. change B. has changed C. changing D. have changed
分析：B。since 1992這類時間狀語通常與現在完成時連用。主句主語是the country life，句中he was used to是省略了關系代詞that的定語從句。
12. Although medical science ______ control over several dangerous diseases, what worries us is that some of them are returning.
A. achieved B. has achieved C. will achieve D. had achieved
分析：B。用現在完成時表示結果或對現在的影響。又如：The streets have been swept free of leaves. 街上的落葉已打掃干凈。
13. — ______ leave at the end of this month.
— I don’t think you should do that until ______ another job.
A. I’m going to; you’d found B. I’m going to; you’ve found
C. I’ll; you’ll find D. I’ll; you’d find
分析：B。第一空用be going to表示打算或意圖，第二空用現在完成時暗示對方應該“先找到新工作，然后再辭職”。注：第二空若不用現在完成時，用一般現在時也可以。
14. This machine ______. It hasn’t worked for years.
A. didn’t work B. wasn’t working C. doesn’t work D. isn’t working
分析：C。此處講的是機器目前的狀況，故用一般現在時。此題所利用的干擾時態是其后的現在完成時。
15. My friend, who ______ on the International Olympic Committee all his life, is retiring next month. (www.yywords.com)
A. served B. is serving C. had served D. has served
分析：D。由于是下個月將要退休，說明現在還在職，據此可排除A和C; 再根據句中的all his life可知要用現在完成時。
16. I ______ in
A. lived B. was living C. have lived D. had lived
分析：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。
17. We ______ our new neighbors yet, so we don’t know their names.
A. don’t meet B. won’t meet C. haven’t met D. hadn’t met
分析：C。后文我們還不知道鄰居的名字，這說明我們還沒有見面，故用現在完成時。
18. Danny ______ hard for long to realize his dream and now he is popular.
A. works B. is working C. has worked D. worked
分析：C。表示從過去一直待續到現在的一段時間，要用現在完成時。
