【题目】______was known to all, he had broken his promise ____he would give us a rise.
A. As; which B. As; that
C. It; that D. It ; which
在线课程【答案】B
【解析】
考查非限制性定语从句和同位语从句。句意：众所周知，他违背了给我们晋升的诺言。第一个空是关系代词as引导的非限制性定语从句，先行词是逗号后面的句子，且先行词在从句中做主语，如果用it做形式主语，all之后就不能加逗号；promise之后引导的是同位语从句，解释说明promise的内容，用that来引导同位语从句。综上所述，选B。
