Question

    Cancer is now the leading cause of death in wealthy countries. Researchers say cancer has replaced heart disease as the top killer in the industrial world.

If the trend continues, they predict cancer could become the leading cause of death worldwide later in this century. However, the news is not that deaths from cancer are increasing but that deaths from CVD（心血管疾病）are decreasing.

CVD is a group of medical conditions that include heart failure, heart attack and stroke. It remains the leading cause of death among middle-aged adults worldwide.

But when you only look at deaths in the industrial world - that is not the case. In those countries, the new report shows that cancer now kills two times as many people as CVD.

The findings were published in The Lancet, The research comes from a large, ongoing study called PURE. It is a project of the Population Health Research Institute of McMaster University and Hamilton Health Sciences in Canada.

The PURE researchers have been collecting information about people from over 20 high-, middle- and low-income countries. The data includes a person's medical history and individual behavior, such as physical activity and diet.

Salim Yusuf is a researcher on the PURE study and a professor of medicine at McMaster University. He also serves as head of the Population Health Research Institute. He explained the study's findings in a statement to the press.

“ The fact that deaths from cancer are now twice as frequent as deaths from CVD in high-income countries, ” Yusuf said,” shows a change in the main cause of death in middle-aged people. ” He added, “ As deaths from CVD decline（减少）in many countries because of prevention and treatment, cancer will likely become the leading cause of death globally in the future.”

1.What does the underlined word “decreasing” mean in Paragraph 2?

A.Falling. B.Lighting. C.Adding. D.Changing.

2.Which of the following is TRUE according to the passage?

A.Cancer has become the leading cause of death around the world.

B.CVD is still the main cause of death among middle-aged adults.

C.Prevention and treatment have helped to make deaths from cancer decline.

D.CVD has replaced cancer as the top killer in the wealthy countries.

3.What can we infer from the last sentence of the passage?

A.There will be no deaths from CVD in the future.

B.Deaths from CVD are the most in high-income countries.

C.Cancer will likely kill more people than CVD will do globally in the future.

D.Most middle-aged people in the world die from CVD.

4.What can we know about PURE from the passage?

A.PURE is a name of a group of researchers from high-income countries.

B.PURE is a project of the Population Health Research Institute of McMaster University and Hamilton Health Sciences in Canada.

C.PURE researchers only study a person's individual behavior.

D.PURE researchers have been collecting information about people from middle-income countries.

【解析】

本文是一篇说明文，主要说明了发达国家人员死因发生了变化，癌症是重要死因，长此以往会成为全世界死亡的重要原因。

1.词义猜测题。根据“cancer has replaced heart disease as the top”可知癌症超过了心血管疾病，后面解释了原因，不是因为癌症死亡人数在增加，而是心血管疾病死亡人数在下降。Falling下降；Lighting照亮；Adding增加；Changing改变。故选A。

2.细节理解题。根据“It remains the leading cause of death among middle-aged adults worldwide.”可知心血管疾病仍然是全世界中年人死亡的主要原因，与B相符。故选B。

3.推理判断题。根据“As deaths from CVD decline（减少）in many countries because of prevention and treatment”可知心血管疾病在减少而不会消失，A错误；根据“The fact that deaths from cancer are now twice as frequent as deaths from CVD in high-income countries”可知癌症是高收入国家死亡率最高的，B错误；根据“cancer will likely become the leading cause of death globally in the future”可知癌症很可能成为世界性最大死因，C正确；D选项未在最后一句提及，D错误。故选C。

4.细节理解题。根据“It is a project of the Population Health Research Institute of McMaster University and Hamilton Health Sciences in Canada.”可知PURE是加拿大麦克马斯特大学人口健康研究所和汉密尔顿健康科学研究所的一个项目。故选B。
