Question

—We were surprised to hear that the reason________ she gave for her absence was________ her mother was ill.
—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　第一句句意为：我们很惊讶地听到她给出的缺席理由是母亲病了。第一空前面的reason在后面的定语从句中作gave的宾语，符合give a reason for的结构，reason用关系代词that/which替代，故排除A、D两项；第二空考查the reason was that...句型，that引导表语从句。所以答案是B项。
