参考答案和解析
正确答案： E
解析：
因为无法判断X国家的性别比例，故条件1无法回答问题；条件2中未涉及得到文凭的女性人数，故也不能推断出答案；将两者综合来看，也无法推断出答案，故本题选E项。

Most Adults in US Have Low Risk of Heart Disease
More than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent.
"I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.
Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.
The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.
Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.
Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.

The main purpose of the passage is to______.
A:introduce that most adults in US adults have low risk of heart disease
B:give treatment measures to reduce the risk of developing heart disease for US adults
C:describe the research made by the Centers for Disease Control and Prevention
D:warn people that they should pay attention to the threat of heart disease immediately

答案：A
解析：
由文章第四段可知，15%的美国成年人有10%到20%的患心脏病风险几率。
由文章第五段可知，受试者中最具心脏病风险的群体比例会随着年龄的增加而增加，而人种和种族对此几乎无影响。国别在此并未提及。
由文章第三段可知，这些发现是基于从13 769位受试者中得到的数据进行分析的结果，故选B。
文章最后一段中提到，需要有积极的治疗方法和公共卫生策略来降低人口总体的患心脏病风险。
本文的开头便引出了文章论述的主题：More than 80 percent of US adults have a less than10-percent risk of developing heart disease in the next 10 years，之后的内容都围绕此论题展开，故选A。

According to the Journal of the American College of Cardiology,_______of the U.S. adults had a risk of developing heart disease above 20 percent in the next 10 years.
A: three percent
B:ten percent
C:twenty percent
D: eighty-two percent

答案：A
解析：
文章首段提到就提到美国80％以上的成年人未来十年内患心脏病的风险低于 10%，故A项正确；由第五段最后一句话“By contrast , race or ethnicity（种族划分）had little effect on risk distributions.”可知种族对患病风险的分布影响很小，故D项正确；由第五段“The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.”可知实验对象年龄越大，在高风险组中所占的比例也越大，男人进入该组的可能性也大于女性，故B项正确，C项错误。
由第四段“Overall , 82 percent of adults had a risk of less than 10 percent , 15 percent had a risk that fell between 10 to 20 percent and 3 percent had a risk above 20 percent.”可知，美国80％以上的成年人未来十年内患心脏病的风险低于10% ,15％的成年人未来患心脏病的风险介于10％～20% ,3％的成年人患心脏病的风险在20％以上。故选A。
题干问的是下列哪个选项对患病风险的分布影响最小。由文中第五段可知，心脏病的患病风险的分布与年龄和性别有很大的关系，种族对患病风险事物分布影响很小，D项“血型”在文中没有提及，故排除。故选C。
由文中原句“15 percent had a risk that fell between 10 to 20 percent”可知，15％的成年人未来十年内患心脏病的风险介于10%～20%，故选C。注意文中的几个百分数不要弄混淆了
两位科学家讲到，尽管大多数成年人10年内患心脏病的风险较低，但在有风险者中，很大一部分所面临的风险却是很高或者刻不容缓的，故只有采取积极的治疗措施和公共卫生政策（Aggressive treatment measures and public health strategies are needed）才能降低所有人群患病的风险概率。

A.sensible
B.senseless

答案：D
解析：
本题考查形容词词义辨析

D选项，句意：我们的感官能力随着年龄的增长而下降。比如说，到60岁的时候，多数人失去了他们40%的嗅觉能力和50%的味觉能力。sensory意为“感觉的，传递感觉的”，综上，D选项正确。

A选项，sensible意为“明智的，合情理的”，故排除。

B选项，senseless意为“失去知觉的，不省人事的”，故排除。

第8题：

About 40 ________ of the population of that country ________ on farms.

A.percents...lives

B.percents...live

C.percent...live

D.percent...lives


正确答案：C
解析：本题考查主谓一致的用法。尽管“40 percent”表达的是数字，但在本句中它所修饰的"population"  指“多少人”，是复数概念，所以谓语动词应该用 “live”。句意：“那个国家百分之四十的人口以农业为生。”
