Ⅱ.阅读理解

Health experts are calling for action to increase cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community(社区)to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two­thirds are in low­income(收入) and middle­income countries.
They discover cancer kills more people in developing countries than AIDS, tuberculosis (肺结核) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It's the number two cause of death in Mexico for women thirty to fifty­four. All over the developing world, it's the number one cancer­related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”
Professor Knaul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower­cost drugs.
1. What would be the best title for the passage?
A. Cancer—a leading cause of death in poor countries
B. What should we do in preventing and treating cancer?
C. What makes the first killer in developing countries?
D. Experts urge more efforts to fight cancer in poor countries.
答案与解析　D　第一段讲癌症一度被误认为是发达国家的健康问题。而一篇医学争辩论文指出癌症也是贫困国家首要致死致残的疾病。在本段末句，哈佛高校和一些其他组织的专家敦促应当像在非洲抗争艾滋病一样来抗争癌症。D项正确。
2．Felicia Knaul's experience in Mexico shows that ________.
A. many Mexican women suffer from breast cancer
B. there is not enough medicine for cancer there
C. many Mexican women can't afford medical care
D. patients with breast cancer are treated differently
答案与解析　D　从文章第四段可知，在墨西哥对富人和穷人乳腺癌患者所实行的治疗措施是不同的。D项正确。
3．From what Felicia Knaul says, we can draw the conclusion that ________.
A. breast cancer is a great threat to young women
B. people don't pay enough attention to breast cancer
C. breast cancer is the second killer among women in Mexico
D. patients can be treated effectively in developing countries
答案与解析　A　从文章第五段可知，乳腺癌是年轻女性的主要致死疾病之一，A项正确。C项错在women in Mexico上，文中有thirty to fifty­four限制women。
4．Which of the following is TRUE according to the passage?
A. The number of cancer cases is decreasing.
B. HIV/AIDS is not being taken seriously in Africa.
C. Over 7.5 million people die of cancer every year.
D. It is very expensive to treat cancer.
答案与解析　C　从其次段第一句可知，C项叙述正确。A项文中未提到；B项与首段末句不符；D项与最终一句不符。

B
Loneliness has been linked to depression(抑郁)and other health problems. Now, a study says it can also spread. A friend of a lonely person was fifty­two percent more likely to develop feelings of loneliness. And a friend of that friend was twenty­five percent more likely to do the same.
Earlier findings showed that happiness, obesity(肥胖) and the ability to stop smoking can also spread like infections within social groups. The findings all come from a major health study in the American town of Framingham, Massachusetts.
The study began in 1948 to investigate the causes of heart disease. Since then, more tests have been added, including measures of loneliness and depression.
The new findings involved more than five thousand people in the second generation of the Framingham Heart Study. The researchers examined friendship histories and reports of loneliness. The results established a pattern that spread as people reported fewer close friends. For example, loneliness can affect relationships between next­door neighbors. The loneliness spreads as neighbors who were close friends now spend less time together. The study also found that loneliness spreads more easily among women than men.
The average person is said to experience feelings of loneliness about forty­eight days a year. The study found that having a lonely friend can add about seventeen days. But every additional friend can decrease loneliness by two and a half days. Lonely people become less and less trusting of others. This makes it more and more difficult for them to make friends — and more likely that society will reject(排斥)them.
John Cacioppo at the University of Chicago led the study. He says it is important to recognize and deal with loneliness. He says people who have been pushed to the edges of society should receive help to repair their social networks.
5．As an average person, if you make 2 more friends, how many days a year might you suffer from loneliness?
A. 48 days. B. 43 days.
C. 65 days. D. 17 days.
答案与解析　B　从第五段可知，平均一个人一年感到孤独的天数为48天，每多交一位伴侣天数削减2.5天。48－2.5×2＝43天。B项正确。
6. What can we infer (推断)from the passage about lonely people?
A. They can overcome loneliness themselves.
B. They will decrease loneliness day by day.
C. They need help to get back to normal social life.
D. They can help others to repair their social networks.
答案与解析　C　依据文章最终一句可知，被社会边缘化的孤独的人群需要挂念来修复他们的社交网络。C项正确。
7．What's the best way to help lonely people according to this passage?
A. Bring them together.
B. Make friends with them.
C. Help them stop smoking.
D. Help them lose weight.
答案与解析　B　从第五段可知，多交伴侣可以使人削减感到孤独的天数，故要挂念这些人最好的方法是和他们交伴侣。B项正确。
8．Which of the following would be the best title for the passage?
A. Loneliness And Social Network
B. Social Networks And Friendship
C. Loneliness And Diet
D. Help a Lonely Person
答案与解析　A　文章介绍了一个关于孤寂人群和其社会网络的一项争辩。A项最适合作文章标题。
