参考答案及解析
31. A. The reason why？ was that？.已成为一种固定句型，这一句中的why和that不能随意换位，也不能将that改成because，尽管that这个词在译文中可能有 因为的含义。
32. B. 非限制性定语从句常用which引导，which表示前句话的整个含义.
33. A. 解释见28题.
34. D. 主句中的two表明不能选A.从句中的are表明不能选B. both of which用来引导非限制性定语从句.
35. C. as引导定语从句时通常构成such？as或the same？as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。as在从句中可以作主语、表语或宾语。本题中as作从句的主语.
36. B. 非限制性定语从句常用which引导，which表示前句话的整个含义.
37. D.
38. D. 解析见35题.
39. A. he makes是定语从句， 从句前省略了关系代词that.
