Question

【题目】If you don't know how ______ new words, _____ in the dictionary.

A. to spell; look up them B. spelling; look them up

C. to spell; look them up D. spelling; look up them

Answer 1

【答案】C

【解析】句意：如果你不知道如何拼写生词，请在字典里查它们。第一空考查疑问词+动词不定式；look up向上看，查阅；此处代词指代的是前面words，复数用名词用them代替，人称代词做动词短语宾语要放在动词后面，副词前面。故选C。
