Question

【题目】The plan being promoted by the White House would give Washington the power to make medical decisions __________ patients.

A. on the behalf of B. represent

C. on behalf of D. B and C

Answer 1

【答案】C

【解析】考查同义词/短语辨析。句意：被白宫一直改进的计划给了华盛顿代表病人作出医疗决定的力量。on behalf of意为“代表……”，构成介词短语。represent是动词，所以不能选B和D。A项短语搭配不对。
