题目分析：
略。
选项分析：
A选项：应将介词with改成of，这是因为，在逻辑上平行的两者是home health care和 other nonhospital services，因此两者应该保证平行，都由介词of引导出来。
B选项：现在分词短语making beneficiaries pay 20 percent of the costs做other non-hospital services的定语。这导致，other non-hospital services主动发出make beneficiaries pay 20 percent of the costs这个动作。在逻辑上，其它的非医院服务不能“使得”受益者付钱，只能让受益者在这些服务中付钱。
C选项：Correct. 本选项在语法和逻辑上均是正确的。
D选项：which is unlike other non hospital services是一个非限制性定语从句，其先行词为home health care。这个定语从句没有问题，问题出现在定语从句身后由连词in that引导的原因状语从句中。在逻辑上，“受益者需要再花20%的成本”和“家庭医疗同非医院服务不相同”这两句话之间没有因果关系。
E选项：other non-hospital services不能主动发出make beneficiaries pay 20 percent of the costs这个动作错误同选项(B)。
句子的整体结构应该是说Medicare covers the full cost of home health care, but (does) not (cover) (the full cost) of other nonhospital services.
A 平行错误；另外，where的用法错误，where引导定语从句的时候，先行词只能是具体的地点名词，排除。
B making beneficiaries pay 20 percent of the costs可以看做伴随状语，修饰整个句子，那么make的主语是medicare，语义不通；也可以看做前面other nonhospital services的后置定语，语义也不通，services本身不能make beneficiaries做什么。
E 同B
D which is unlike other ...如果修饰的是前面的home health care, 意思就成了home health care is unlike other nonhospital services in that ...，两个事之间没有因果关系，又或者一般我们会讲“A不像B，A怎么着怎么着”，不会讲“A不像B，B怎么着怎么着”？
