Question

【题目】-Is this the new dictionary _ you got yesterday?

-Yes. Now it's very convenient for me to look up words.

A. that B. why C. what

Answer 1

【答案】A

【解析】句意：——这是你昨天买的新的字典吗？——是的，现在对于我来说记单词是非常方便的。A. that那个；B. why为什么；C. what什么。这里是定语从句，先行词在里是the new dictionary，是物，这里用that引导的，why和what不能引导定语从句。根据题意，故选A。
