Question

【题目】The first thing_______ I am going to do this evening is to write to my father.

A.that B. which C. who D.what

Answer 1

【答案】A

【解析】

试题分析：句意：我今晚打算做的第一件事是写信给我的爸爸。what是疑问词，不能作关系代词。that、which、who均可作关系代词，which用来指物，who用来指人，that既可以指人又可以指物。当先行词前有序数词修饰时，关系代词只能用that。根据题意，先行词thing前有the first修饰。故选A。
