Question

【题目】The Silk Road________new markets in Europe and America in the old days.

A.built upB.opened upC.put upD.looked up

Answer 1

【答案】B

【解析】

句意：丝绸之路在古代开辟了欧洲和美洲的新市场。

考查动词短语辨析。built up逐步增长；opened up打开/开放，使（地方、经济、兴趣领域等）开放；put up挂起/建造；looked up查阅。根据空后的“new markets in Europe and America ”可知是“开辟欧洲和美洲的新市场”应该用短语open up。故选B。
