Question

【题目】Scientists are studying animals to look for proof _____ they have feelings similar to ours.

A.thatB.whatC.whetherD.which

Answer 1

【答案】A

【解析】

考查同位语从句。句意：科学家们正在研究动物，以寻找它们与我们有相似感觉的证据。抽象名词proof之后的从句they have feelings similar to ours不缺少句子成分，说明了proof的具体内容，因此是proof的同位语从句，且从句结构和意思完整，故用that引导。故选A项。
