Question

【题目】The first thing I’m going to do is to send an e-mail to Peter.

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

Answer 1

【答案】C

【解析】

试题分析：句意：我要做的第一件事是给彼得发一封邮件。I’m going to do作为the first thing的定语。先行词指事物时，定语从句用that，which作关系词；先行词指人时，用who, whom, that作为关系词。the first thing指事物，先行词受the first修饰时，关系词只能用that。故选C。
