Question

【题目】When __________ a new word, you'd better __________ a dictionary.

A. come across; consult B. coming across; refer to

C. coming across; look up D. come across; consulting

Answer 1

【答案】B

【解析】考查省略句以及动词短语辨析。句意：当你遇到生词时，最好查查词典。when引导的是一个省略句，故第一空用coming across；“查词典”可以说 look up a word in a dictionary; consult 和refer to 都有“参考，查阅”的意思，但you'd better后接动词原形，故选B。
