Question

【题目】There is nothing ambiguous ___ all illegal immigrants should be sent back across the border immediately.

A. that B. which

C. whether D. when

Answer 1

【答案】A

【解析】考查同位语从句。句意：毫无疑问，所有非法移民都应该立即被送回边境。根据句意及句子成分分析可知，此处引导的从句是对nothing ambiguous的解释说明，属于同位语，而从句中的句子成分齐全，所以应使用只起连接作用的代词that引导。故选A。
