Question

—Yes，we saw her mother was at the supermarket that morning.

A．why；that

B．which；that

C．that；because

D．why；because

Answer 1

B

解析试题分析：句意：我们很惊讶的听说她为缺席给出的理由是她妈妈病了。--是的，我们看见她妈妈那天早上在超市的。第一空是定语从句的关系词，先行词是the reason，定语从句中介词for后面缺少宾语，所以用关系代词that或which，不能用why，第二空是连接表语从句的连接词，主语是the reason的时候，表语从句用that连接，所以选B。
考点：考查定语从句和表语从句
