【正文】 關系代詞that引導定語從句，并在從句中作主語。50. B. 本句話中，主句的主語是all,為抽象概念。49. C. 因為是two ballpens, 并且定語從句的謂語writes是單數(shù)概念。其它選項結構不對。47. B. 為便于理解，改寫本句話：This is the school that some Germanfriends visited last week. 不難看出，作表語的the school是先行詞。46. B. through which引導定語從句，through which即through the hole,在定語從句中作狀語。44. D. that followed是定語從句，關系代詞that在從句中作主語。本句話主句的主語是The number of指“…..的數(shù)目”，是單數(shù)概念。as在從句中可以作主語、表語或賓語。29. D. for which在定語從句中作原因狀語,可用why 來替代.30. B. which I have looked after 構成一個非限制性定語從句.31. A. The reason why… was that….已成為一種固定句型，這一句中的why和that不能隨意換位，也不能將that改成because，盡管that這個詞在譯文中可能有 “因為”的含義。 as在從句中可以作主語、表語或賓語。從句可放在主句后，也可置于主句前。這時as所指代的不是主句中某個名詞，而往往指代整個主句的含義。about是介詞，其后要用which作賓語，不能用that。如果句中的one前面使用了定冠詞the，則the one應該視為先行詞。7. A. 解析見第3題。其他幾個答案都不能作賓語。4. C. when是關系副詞，表示時間，在定語從句中作時間狀語。whom是關系代詞，作介詞to的賓語，可以省略。 that 47.
