Studies Show U.S. Spending Doesn't Get Best Health

The United States may spend twice as much on health care as other rich countries but it is not getting results to match, according to studies released on Tuesday.
But in the study of five wealthy countries, published in the journal Health Affairs, researchers found no single nation had clearly the worst or best health care system.
Gerard Anderson at Johns Hopkins University's school of public health and colleagues came up with a list of 21 health fields they could evenly compare across the five countries--Australia, Canada, Britain, New Zealand and the United States.
"None of the five countries is consistently the best or the worst on all 21 indicators. " Anderson said during a telephone briefing for reporters.
"If you are looking for the place to get the best care. there isn't a single place. Every country has at least one indicator where it scores the best of the five countries and each country has at least one indicator(指标) where it scores the worst of the five countries. "
But,he said, the United States is not getting value for money. "The United States should be particularly concerned about these results, given that we spend twice as much on health care as any other country. So spending more doesn't necessarily result in better outcomes. "
Anderson's group of international health experts sponsored by The Commonwealth (联邦)Fund spent five years working on the study, getting the latest possible data from the five countries on areas such as breast cancer and leukemia (白血病) survival, suicide rates, death rates from asthma (哮喘 ), vaccination (种痘) rates and cancer screening.

【答案解析】[解析] 第二段说But in the study of five wealthy countries，published in the journal Health Affairs，researchers found no single nation had clearly the worst or best health care system.(5个富有的国家中没有哪个国家的健康保健体系被认为最糟糕的或最好的)第五段也提到Every country has at least one indicator where it scores the best of the five countries and each country has at least one indicator(指标)where it scores the worst of the five countries.因此该问题句不正确。

单选题 Each year, the U.S. spends more money on health care than the previous one.

单选题 The more a country spends on health care,the better care its people enjoy.

【正确答案】 B

【答案解析】[解析] 该句的说法与文章主题(文章标题内容Studies Show U.S.Spending Doesn't Get Best Health)不一致。文章第六段说But，he said，the United States is not getting value for money．“The United States should be particularly concerned about these results，given at we spend twice as much on health care as any other country.So spending more doesn't necessarily result in better outcomes.”该段表达的内容是“花费更多未必会带来更好的结果”，可见问题句的说法与该句的内容不一致，因此判断问题句的说法错误。

单选题 The study involved 5 countries and lasted 5 years,

【正确答案】 A

【答案解析】[解析] 问题句中出现了两个具体的数字，很显然对这两个数字的判断是关键。第二段提到：But in the study of five wealthy countries,published in the journal Health Affairs，researchers found no single nation had clearly the worst or best health care system.第七段提到Anderson's group of international health experts sponsored by The Commonwealth Fund spent five years working on the study.5个国家和5年都提到了，因此是正确的。

单选题 The other four countries provide better health care than the U. S.

【正确答案】 B

【答案解析】[解析] 问题句把研究中的5个国家在健康保健方面的工作效果进行了比较，因此注意文章中进行比较的句子。文中出现The United States may spend twice as much on healthcare as other rich countries but it is not getting results to match,according to studies released onTuesday.But in the study of five wealthy countries,published in the journal Health Affairs，researchers found no single nation had clearly the worst or best health care system. 以上句子的内容是说“这5个国家没有谁在健康保健方面最好或最坏”，而问题句说“其余四个国家都比美国好”，很显然这个推断是与原文内容不一致的，因此判断问题句的说法不正确。
