答案

21. B. 考查非限制性定语从句，all of whose homes = all of their homes他们所有的房子。

22. D. 因为先行词是前面整个句子，且在从句中作主语，所以用which。of course是插入语。

23. D. 将疑问句改为陈述句：this research center is…显然缺少先行词，必须加上代词the one来作先行词，又因定语从句不缺主语或宾语，所以用关系副词where。假若在this后加the，就选where，请想想这是为什么。

24. A. 因为先行词是the days，并在定语从句中作状语。

25. B. 当先行词前有so时，用as引导定语从句，as在从句中作主语或宾语。假若在lift后加上it，答案就是that了，请想想这是为什么。

26. C. 因前后均的句子，必须要选连词，排除B和D;又因在介词后不能用that来引导定语从句，所以选C。during which time在那段时间里。

27. A. which用作关系代词，在定语从句中作主语。

28.C. "和谁讲话”要说speak to sb. 本题全句应为

Do you know the man whom I spoke to.。whom是关系代词，作介词to的宾语，可以省略。

29. D. where是关系副词，表示地点，在定语从句中作地点状语。

30. C. when是关系副词，表示时间，在定语从句中作时间状语。
