　　答案

　　21. B. 考查非限制性定語從句，all of whose homes = all of their homes他們所有的房子。

　　22. D. 因為先行詞是前面整個句子，且在從句中作主語，所以用which。of course是插入語。

　　23. D. 將疑問句改為陳述句：this research center is…顯然缺少先行詞，必須加上代詞the one來作先行詞，又因定語從句不缺主語或賓語，所以用關(guān)系副詞where。假若在this后加the，就選where，請想想這是為什么。

　　24. A. 因為先行詞是the days，并在定語從句中作狀語。

　　25. B. 當(dāng)先行詞前有so時，用as引導(dǎo)定語從句，as在從句中作主語或賓語。假若在lift后加上it，答案就是that了，請想想這是為什么。

　　26. C. 因前后均的句子，必須要選連詞，排除B和D;又因在介詞后不能用that來引導(dǎo)定語從句，所以選C。during which time在那段時間里。

　　27. A. which用作關(guān)系代詞，在定語從句中作主語。

　　28.C. "和誰講話”要說speak to sb. 本題全句應(yīng)為

　　Do you know the man whom I spoke to.。whom是關(guān)系代詞，作介詞to的賓語，可以省略。

　　29. D. where是關(guān)系副詞，表示地點，在定語從句中作地點狀語。

　　30. C. when是關(guān)系副詞，表示時間，在定語從句中作時間狀語。
