制约与平衡

21. GWD17-Q21:

Medicare, the United States
government’s health insurance program for the elderly and disabled, covers the full cost of home health care, but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries.


A.but not with other nonhospital services where 20 percent of the costs must be paid by beneficiaries

B.but not of other nonhospital services, making beneficiaries pay 20 percent of the costs

C.but not of other nonhospital services, for which beneficiaries must pay 20 percent of the costs

D.which is unlike other nonhospital services in that 20 percent of the costs must be paid by beneficiaries

E.which is unlike other nonhospital services that make beneficiaries pay 20 percent of the costs

可以排除直接DE。可是不明白ABC都是个什么结构，but not of 怎么用。希望听听大家的回答，谢谢！

制约与平衡

谢谢！没想到你两个都答了，呵呵。

newalan

but not of 实际是省略结构，完整的应该是but not covers cost of other nonhospitalservices...所以只在BC中选择。
另外切记，原句中的情态不能随意省略。所以选C
