{01}His parents were teachers in that school, _______ lost their lives in order to save
their students in the earthquake.   A.none of them B.both of them C.none of whom D.both of whom 解析：
试题分析：经过分析，可知这个句子中包含一个非限制性定语从句。Them不能引导定语从句，又因为His parents是两个人，表示两者故用both。
点评：分析清楚句子结构是关键，根据关系词在从句中所作的成分以及含义，选择正确的关系词。
本题选D。
{02}The American economy is still in trouble，________ the Chinese economy is beginning to pick up. A.when B.however C.while D.therefore 解析：这两个分句之间是明显的转折关系，表示对比，所以选C 。
本题选C。
