答案及解析：文章的第一句话反映了全文的主题：美国以在本世纪取得的医疗方面的成就而感到自豪，为了解全文大意提供了思路。1.A 根据前面cures（治疗）和后文内容提示确定。2.C such as 是固定搭配，表示列举。3.C 四个选项中只有 cold 是病名，表示“感冒”,与前面几个表示病名的并列。4.B 先排除C和D ，因C、D所表示的内容均不能与learned 搭配，A表示的内容与上面提到的医疗成就相反，只有B表示的内容与上面提到的医疗成就对应。5.A as well 在句末表示“也”，尽管B和C 也可以表示“也”但“either”用于否定句，“also”用于肯定句句子中, “therefore”的意思与该句不搭配。6.B 与医疗成就及第4 空的答案相对应。7D.结合上下文可以知道这里应是“医院”而不是其它。8.B “设备最好”与“现代化”相并列。9.B “达到”不定式短语作主语。10.A “设备最好与现代化”当然需要“昂贵的代价”。11.B 凭常识和本段内容确定。12.C 表示 转折与上句衔接。13.A 与本段内容相符而且从语法上判断，B=C ，不可能有双重答案，选D 则时态不符。14.A 这里是where 引导的定语从句，where 在定语从句做地点状语。15.B 承接上下文内容，说到plan 之内容。16.B 起承上启下作用，表示“于是”。

17.C A和D 两项不合题意，而B 项仅局限于“检查”，不能包括“医疗保健、治疗”等整体含义，故选C ：医疗费用的帮助 。18.B A和D 两项不合文章意义，而C项缺少of 。19.A B和D 两项填入句中意义不完整，C项意义不清。20.A 结合上下文这里是“需要”的意 思.
