Question

When you don’t know some words in reading, it is not a good idea in a dictionary at once.

A. make up them B. looking up them

C. to make them up D. look them up

 

Answer 1

C

【解析】

试题分析：look sth up in a dictionary表示固定词组查字典，如果是代词必须放在中间；

句意：当你在读书的时候不知道一些新的单词时，立刻查字典不是一个好主意，结合句意，故选C

考点：考查动词短语辨析。
