Chronic Diseases: The World's Leading Killer

Chronic diseases are the leading cause of death in the world. Yet health experts say these conditions are often the most preventable. Chronic diseases include heart disease, stroke, cancer, diabetes(糖尿病) and lung disorders.
The World Health Organization says chronic diseases lead to about seventeen million early deaths each year. This United Nations agency expects more than three hundred eighty million people to die of chronic diseases by two thousand fifteen. It says about eighty percent of the deaths will happen in developing nations.
The WHO says chronic diseases now cause two-thirds of all deaths in the Asia-Pacific area. In ten years it could be almost three-fourths. People are getting sick in their most economically' productive years. In fact, experts say chronic diseases are killing more middle-aged people in poorer countries than in wealthier ones.
The WHO estimates that chronic diseases will cost China alone more than five hundred thousand million dollars in the next ten years. That estimate represents the costs of medical treatment and lost productivity. Russia and India are also expected to face huge economic losses.
Kim Hak-Su is the head of the United Nations Economic and Social Commission for Asia and the Pacific. Last week in Bangkok he presented a WHO report on the problem. It says deaths from chronic diseases have increased largely as the result of economic gains in many countries.
The report details the latest findings from nine countries. They include Brazil, Britain, Canada, China, India and Nigeria. The others are Pakistan, Russia and Tanzania.
Mister Kim says infectious and parasitic (寄生的) diseases have until recently been the main killers in Asia and the Pacific. But he says they are no longer the major cause of death in most countries.
Health officials say as many as eighty percent of deaths from chronic diseases could be prevented. They say an important tool for governments is to restrict the marketing of alcohol and tobacco to young people. Also, more programs are needed to urge healthy eating and more physical activity.
UN officials aim through international action to reduce chronic-disease deaths by two percent each year through two thousand fifteen. They say meeting that target could save thirty-six million lives. That includes twenty-five million in Asia and the Pacific.
单选题 How many people in developing countries will probably die of chronic diseases by 2015?
【正确答案】 C
【答案解析】[解析] 细节题。从第二段中我们知道“This United Nations agency expects more than three hundred eighty million people to die of chronic diseases by two thousand fifteen. It says about eighty percent of the deaths will happen in developing nations.”即2015年发展中国家慢性病的死亡人数应该是380,000,000的80%,也就是304,000,000。
单选题 Due to chronic diseases China will have to face ______.
【正确答案】 D
【答案解析】[解析] 理解题。从第四段中的“The WHO estimates that chronic diseases will cost China alone more than five hundred thousand million dollars in the next ten years.”可知,慢性疾病对中国来说意味着很大的经济损失。因此选项C是正确的。
单选题 Which can NOT be learned from the passage?
【正确答案】 C
【答案解析】[解析] 理解题。第三段中“experts say chronic diseases are killing more middle-aged people in poorer countries than in wealthier ones.”只是讲与富裕国家的中年人相比,贫困国家有更多的中年人会因慢性病死亡。并未对比中年人与老年人的情况,因此C的表述是错误的。另外选项A、B、D分别可以在第八、第七和第五段找到对应的表述。
单选题 Until recently the main killers in Asia and the Pacific have been ______.
【正确答案】 D
【答案解析】[解析] 理解题。从第七段的“infectious and parasitic(寄生的)diseases have until recently been the main killers in Asia and the Pacific. But he says they are no longer the major cause of death in most countries.”中我们知道传染性疾病和由寄生虫引起的疾病仍然是亚洲和太平洋地区最主要的杀手。但是,它们不再是导致全球绝大多数国家人口死亡的主要原因。因此选项D是正确答案。
单选题 Which is NOT mentioned as a way to prevent chronic-disease deaths?
【正确答案】 A
【答案解析】[解析] 细节题。倒数第二段对选项B、C、D都有提及,文中并未提到A,因此选择A。
