Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (認(rèn)知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
1.There is less research on overweight and cognitive functions because researchers _____.
A. believe overweight only affects our body
B. have focused on ways to sharpen people’s mind
C. do not consider overweight a main cause for low cognitive ability
D. are clear about the relation between weight and mental functions
2.The result of Gunstad’s study shows that ______.
A. losing weight has little effect on people’s memory
B. losing weight can improve people’s mental functions
C. overweight people are likely to have psychology problems
D. overweight people’s abilities of concentration differ greatly
3.What is Gunstad planning to prove next in his research?
A. Slim people are smarter than overweight people.
B. Healthy diet is better than exercise in losing weight.
C . Traditional ways of losing weight are better than operation.
D. Overweight people will get smarter by taking more exercise.
4.Which of the following is the best title for th e text?
A. Body Weight and Health

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激),” Edwards points out. “The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry,” Beck says. “But it's amazing how quickly we have given up that belief.”
“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds.”
1.The purpose of Beck and Edwards’ study is to ____.
A. understand human-animal relationship
B. find the causes of old people’s loneliness
C. make lonely old people’s life better
D. promote the animal-assisted research
2.In the research, the old people are asked to ____.
A. note the activities of AIBOs
B. keep AIBOs at home for 12 weeks
C. analyze the collected information
D. record their feelings and activities
3.What is the advantage of AIBO over live dogs?
A. It can watch TV with its owner.
B. It can help the disabled people.
C. It responds to all the human orders.
D. It is easier to keep at home.
4.The author seems to suggest that the future robotic dogs may ____.
A. keep old people active
B. cure certain diseases
C. change people's beliefs
D. look more like real dogs

Coffee is a powerful beverage.On a personal level,it helps keep US awake and active.On a much broader level,it has helped shape our history and continues to shape our culture.
Coffee didn’t take off until the l400s when people figured out they could roast its seeds.By the l500s,the drink had spread to coffeehouses across the Arab world.Within another l50 years,it took Europe by storm.
“It actually had a major impact on the rise of business,” historian Mark Pendergrast says.Coffeehouses became a spot not just to enjoy a cup but to exchange ideas.The insurer Lloyd’s of London was founded hundreds of years ago in one of London’s 2,000 coffeehouses.Literature,newspapers and even the works of great composers like Bach and Beethoven were also spawned(涌現(xiàn))in coffeehouses.
It is often said that after the Boston Tea Party of l773,when American colonists attacked British tea ships and threw boxes of tea into the harbor,Americans universally switched over to drinking coffee.In a letter John Adams wrote to his wife,Abigail,the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead,because drinking tea had become a symbol of not loving the country.
For all the upsides coffee has brought the modern world,it also led to its fair share of downsides,too.Europeans carried coffee with them as they colonized various parts of the world,and this frequently meant they enslaved people in order to grow it.In Brazil — where slavery was legal until l888 — coffee plantations would use slash-and-burn agriculture,tearing down rain forests and planting coffee trees.Once the soil had been exhausted,growers would move on to another place.
And yet,coffee,as Pendergrast says,”had a very good impact in many ways on our civilization,even though it was,for a long time,grown by slaves.”
1.Why did people enjoy going to coffeehouses?
