World Health Report 2002

The life expectancy (平均寿命) of people around the world could increase by five to ten years if action against common health risks (冒险，风险) is taken．This is one of the findings in this year’s World Health Report released (发布) recently by the World Health Organization．The report is called “Reducing Risks，Promoting (促进) Life”．

Researchers found that ten major threats to good health are common around the world．The chief of the World Health Organization，Gro Harlem Brundtland，called them the ten leading killers．They include unsafe sex，poor nutrition (营养)，high blood pressure，use of tobacco and alcohol，unsafe water and unclean living conditions．Also included are high levels of dangerous fat in the blood，indoor smoke from solid fuels，a lack of iron in the body and too much body weight，or obesity (肥胖)．Together，these ten health risks make up forty percent of the fifty-six million deaths worldwide each year．

Doctor Brundtland called for reducing the ten main health risks by twenty-five percent within ten years．If this were done，life expectancy in industrial countries could increase by ten years．In developing countries，it could increase by five years．

Currently (通常地)，the number of life years lost because these health risks differ around the world．Doctor Brundtland says the differences these health risks create between rich and poor nations are shocking (骇人听闻的)．For example，about one-hundred-seventy-million children in poor countries are underweight. They do not weigh enough because they do not get enough food. However, more than one thousand millionお adults around the world are too fat. These people are mostly in rich, industrial countries.

Doctor Brundtland warns that the cost of inaction is serious. For example, she says nine million deaths a year linked to smoking will be reported by two-thousand–twenty if steps are not taken soon. Currently, about five millionお people die each year from diseases related to smoking.

Doctor Brundtland says that AIDS (艾滋病) and the HIV virus (艾滋病病毒) are having a huge effect on the length of life in Africa. Currently, life expectancy at birth in southern Africa is forty-seven years. The WHO estimates (估计) that ninety-five percent of HIV infections (感染) in Africa were caused by unsafe sex. She says there is an urgent need for sex education and the use of condom devices (孕器具) to prevent the spread of HIV.

Judge the following sentences true (T) or false (F).

1.It is certain that life expectancy of people around the world could increase by five to ten years in future.

1.　　 Most of the deaths worldwide each year are due to (由于) the ten leading killers such as unsafe sex, poor nutrition, high blood pressure and so on.

3.From the passage, we can infer that so far people haven’t dealt with smoking effectively.

4.The length of life in Africa is affected most by AIDS.

While researchers have long shown that tall people earn more than their shorter counterparts, it's not only social discrimination that accounts for this inequality -- tall people are just smarter than their height-challenged peers, a new study finds.
"As early as age three -- before schooling has had a chance to play a role -- and throughout childhood, taller children perform significantly better on cognitive tests," wrote Anne Case and Christina Paxson of Princeton University in a paper published by the National Bureau of Economic Research.
The findings were based primarily on two British studies that followed children born in 1958 and 1970, respectively, through adulthood and a U.S. study on height and occupational choice.
Other studies have pointed to low self-esteem, better health that accompanies greater height, and social discrimination as culprits(罪犯) for lower pay for shorter people.
But researchers Case and Paxson believe the height advantage in the job world is more than just a question of image.
"As adults, taller individuals are more likely to select into higher paying occupations that require more advanced verbal and numerical skills and greater intelligence, for which they earn handsome returns," they wrote.
For both men and women in the United States and the United Kingdom, a height advantage of four inches equated with a 10 percent increase in wages on average.
But the researchers said the differences in performance crop up long before the tall people enter the job force. Prenatal care(产前护理) and the time between birth and the age of 3 are critical periods for determining future cognitive ability and height.
"Prenatal care and prenatal nutrition are just incredibly important, even more so than we already knew," Case said in an interview.
Since the study's data only included populations in the United Kingdom and the United States, the findings could not be applied to other regions, Case said.
And how tall are the researchers?
They are both about 5 feet 8 inches tall, well above the average height of 5 feet 4 inches for American women.
51. What can be learnt from the study of Anne Case and Christina Paxson is that ______.
A. the reason for lower pay for shorter people is social discrimination
B. taller children perform significantly better on cognitive test
C. tall people earn more than shorter counterparts
D. prenatal care and prenatal nutrition are less important than we already knew
52. Which period is the most important for determining future cognitive ability and height?
A. between age 3 and schooling         B. between birth and the age of 3
C. the whole childhood                   D. between 1958 and 1970
53. The underlined phrase “crop up” in the Eighth Paragraph is closest in meaning to ______.
A. get in       B. rise up        C. come up       D. stand up
54. The best title for this passage would be _______.
A. Tall people earn more than shorter counterparts
B. A study on height and occupational choice
C. The difference between tall people and short people
D. Taller people are smarter

You can make the difference between this … and this. But how?
This summer, join the International Conservation Scouts on a fun—filled holiday with a difference. Year after year, young people from all around the world get together at one of our sixteen conservation camps. Their shared aim is to help protect the countryside and its wildlife.
Many animals and plants are in danger of disappearing forever. The dormouse, a kind of mouse, for example, needs woodland plants for food and trees to stay in. Its habitat is being destroyed by man and it needs our help to survive.
On a conservation camp holiday, you’ll learn all about nature and how to protect it. Our trained leaders will accompany you and tell you everything you need to know. Because of this you don’t need any experience, just energy and enthusiasm. You will explore the countryside and work to ensure the survival of hundreds of animals and plants and still have plenty of time to enjoy the camp’s excellent sport games and organized nature paths through beautiful scenery.
The International Conservation Scouts is a world—wide organization, so there must be a camp near you. You can spend a splendid holiday at any of the camps for as little as ￡60, including accommodation and food.
