Question

【题目】The reason ________ he gave for his being away for such a long time is ________ his mother was ill.
A.why; that
B.that; that
C.that; because
D.why; because

Answer 1

【答案】B
【解析】句意：他说的离开这么久的原因是他妈妈生病了。先行词为表原因的the reason，且从句中的gave缺宾语，所以第一空用关系代词that或which用作gave的宾语，that 或which可以省略；第二空是由that引导的表语从句，即The reason …is（was） that…句式。
