Question

【题目】When you ____ the road, you should look left and right before going ____ it.

A. cross, across B. cross, cross C. across, cross D. across, across

Answer 1

【答案】A

【解析】

句意：当你过马路时，在过马路前应该左右看。考查词性转换。cross：穿过，动词；across：穿过，介词；第一句（when引导的时间状语从句）缺少谓语动词，可知填cross；第二句有动词going，可知填介词across，go across=cross；选A。
