Question

Chinese vessels ________ 646,000 square kilometers in the southern Indian Ocean in search of the missing Malaysian flight MH370.

A．have covered

B．have looked

C．has travelled

D．had searched

Answer 1

A

试题分析：考查动词辨析。句意：中国的海事船已经覆盖了南印度洋646000平方千米的海域，来搜寻马来西亚失联客机MH370。cover有“覆盖，走过（一段路程）”的意思，search后跟地点或要搜寻的人或物，这里与kilometers不搭配，故选A。
