If you don’t know how to spell the new word, please in the dictionary.

A. look at

B. look them up

C. look up it

D. look it up

答案：

A. look at

B. look them up

C. look up it

(答案→)D. look it up

解析：look at看；look up向上看，查阅；句意：如果你不知道如何拼写这个新单词，请在字典里面查阅它。此处代词指代的是前面word，单数用名词用it，it主格宾格形式一样，人称代词做动词短语宾语是要放在动词后面，介词前面。故选D。
