Residents in the poorest counties in the U.S. face a life expectancy up to decade shorter than their counterparts in the wealthiest areas, according to a study published in the American Journal of Public Health.

Researchers from East Tennessee State University wanted to better understand how socioeconomic status was associated with health outcomes. To find out they divided the country’s 3,141 counties into 50 new ‘states’ (with 2 percent of the counties in each) based on household income as opposed to geographic proximity (接近).

The researchers broke down the data by county since they found state-level data may hide some ‘impact of socioeconomic differences on both the best-off and worst-off counties.’ They then examined health data from the wealthiest and poorest ‘states’ (top and bottom 2 percent) to see how residents differed on factors like smoking, clinical care and excessive drinking. Researchers found that there was nearly a 10-year gap in the life expectancy of men with an average of 79.3 years in the wealthy counties compared to 69.8 years in the poorest. For women, the difference was slightly less - 83 years in the wealthiest counties and 76 years in the poorest.

The study authors caution that while they found a connection between socioeconomic status and health outcomes, they did not analyze cause and effect. But they suggest that the data shows how policy makers should not just focus on state-wide initiatives (主动性) but more targeted efforts to help those most at risk. “With limited resources, methods of pinpointing the poorest counties can assist in the allocation of resources and programs to those communities that are in the greatest need,’’ the study authors wrote.

A.By social status.B.By income.

A.The researchers think their study is perfect.

【推荐1】Children think other youngsters who wear glasses look smarter and are more honest than those who don't wear glasses, according to a U.S. study of 80 children. In addition, the researchers found that children seldom judge peers wearing glasses in terms of appearance.

The study included 42 girls and 38 boys, aged 6 to 10.Of those, 30 wore glasses, 34 had at least one classmate with glasses, and almost two-thirds had at least one parent who wore glasses. The study participants were shown 24 pairs of pictures of children. The children in each pair of pictures differed by gender and race, and each pair of pictures included one child with glasses and one child without glasses. The children were asked a series of questions about each pair of photos. About two-thirds said children wearing glasses looked smarter than those without glasses, and 57 percent said children wearing glasses looked more honest.

These findings may help comfort children as they're fitted for their first pair of glasses, lead author Jeffrey Walline, an assistant professor of optometry at Ohio State University, suggested in a prepared statement. "If the impression of looking smarter will appeal to a child, I would use that information and tell the child it is based on research. Most kids getting glasses for the first time are sensitive about how they're going to look. Some kids simply refuse to wear glasses, because they think they'll look ugly," Walline said.

1. What impression may a youngster wearing a pair of glasses leave on his classmate?
A.Ugly.B.Easygoing.C.Dynamic.D.Intelligent.
2. Which of the following is correct about the participants of the study?
A.Most of them wore glasses at an early age.
B.Most of them had one family member wearing glasses.
C.They observed children of different ages in each picture.
D.They were required to answer the same questions.
3. Why may the result of the study comfort the children first wearing glasses?
A.Because the study is carried out in a scientific way.
B.Because it convinces them of the necessity of wearing glasses.
C.Because it may help remove all their initial worries.
D.Because the children do care about being smarter.
4. What is the best title of this article?
A.Wearing Glasses, Smarter Looking.B.Wearing Glasses, More Intelligent.
C.Concerns on Wearing Glasses.D.Wearing Glasses, a New Trend.

【推荐2】For centuries, apple growers in Japan’s Aomori Prefecture have been creating good-looking apples by using “Mojie Ringo”. The process is fairly simple. It basically shelters the apples from sunlight for a period of time and then applies stencils(蜡纸)to ensure that part of the apple skin remains discolored. More often than not, Mojie Ringo apples are decorated with messages and symbols of good fortune, and are offered as gifts.

Large apple varieties like Mutsu or Stark Jumbo are most suitable for Mojie Ringo, as they provide more surface area for complex design. Preparation begins in January, with a pruning(剪枝)operation, to ensure that remaining flowers receive plenty of sunlight. Then, growers hand-pollinate (人工授粉)each of the apple tree flowers, and then once fruits begin to form, they are covered with several layers of plastic bags to protect them from both pests and sunlight.

Keeping the apples “in the dark” for long periods of time increases their photosensitivity(光敏性), so when the plastic bags are finally removed, they begin to produce a component that turns the skin red. During the final stage of the Mojie Ringo process, stencils are applied on the surface of the apple to ensure that only the skin around the stencil turns red.

The stencils are removed during harvesting, to expose the almost white skin underneath. The stencils need to be flexible, because the fruits continue to grow, and otherwise the designs could be compromised.

According to Culture Trip, Mojie Ringo was perfected by farmer Hamo Iwasaki from Aomori Perfecture, whose son, Chisato Iwasaki, is widely regarded as one of the most talented apple artists today.

Although Mojie Ringo seems fairly simple, it requires a lot of work and patience over long periods of time, and for many growers the effort and attention just don’t pay off enough. That’s why the old tradition is slowly fading, with only a few Aomori fruit gardens producing the eye-catching fruits.

1. Mojie Ringo is mainly used to improve the ________ of apples.
A.productionB.attractionC.tasteD.shape
2. What does the underlined word “they” in paragraph 3 refer to?
A.applesB.stencilsC.plastic bagsD.apple growers
3. Why do many fruit growers reject Mojie Ringo?
A.Because they aren’t familiar with it.
B.Because it is an out-of-date tradition.
C.Because it isn’t economically worthwhile.
D.Because fruits coming from it aren’t popular.
4. What’s the text mainly intended to introduce?
A.A new apple variety.B.A talented apple artist.
C.An apple planting center.D.An apple fanning technique.

【推荐3】If your job requires a lot of sitting,you could be putting your health at danger.

The American Journal of Epidemiology(流行病学)did a study in 2010 on the connection between sitting and an individual's physical health.In the study,53,440 working men and 69,776 working women were surveyed on their time spent sitting.The subjects were all disease free when employed.The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.

The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hour a day,and men had an approximately 20 higher death rate.

Well,now is a fine time to get this information.But why didn't they tell me this years ago?I would have planned on taking a more active job instead of the sedentary(坐着的)job of an editor.

So what can you do if you have to work for a living at a job that requires a lot of sitting?Here are some ideas:

Take frequent breaks.It is recommended that workers vary activities,change their position,and take short breaks every 20 minutes to rest muscles and increase blood circulation.Get a standing desk.Some studies have shown that working from an upright position may be better for health.The serious fitness people can even purchase a treadmill (跑步机)desk.It only goes about one mile per hour.Have a walking meeting.If your group is kind of small,going for a walk while discussing topics is a good alternative.

1. According to the text,the study in 2010      .
