问题补充:
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。
