    Modern lifestyles are generally quite different from those of our hunter-gatherer ancestors, a fact that some claim as the cause of the current rise in global obesity, but new results published July 25 in the open access journal PLOS ONE find that there is no difference between the energy expenditure(耗费) of modern hunter-gatherers and Westerners, casting doubt on this theory.

    The research team behind the study, led by Herman Pontzer of Hunter College in New York City, along with David Raichlen of the University of Arizona and Brian M. Wood of Stanford measured daily energy expenditure among the Hadza, a population of traditional hunter-gatherers living in the open Savannah of northern Tanzania. Despite spending their days hiking long distances to seek for wild plants and game, the Hadza burned no more calories each day than adults in the U.S. and Europe. The team ran several analyses accounting for the effects of body weight, body fat percentage, age, and gender. In all analyses, daily energy expenditure among the Hadza hunter-gatherers was indistinguishable(难以区分的) from that of Westerners. The study was the first to measure energy expenditure in hunter-gatherers directly; previous studies had relied entirely on estimates.

    These findings overturn the long-held assumption that our hunter-gatherer ancestors expended more energy than modern populations, and challenge the view that obesity in Western populations results from decreased energy expenditure. Instead, the similarity in daily energy expenditure across a broad range of lifestyles suggests that habitual metabolic(新陈代谢的) rates are relatively constant among human populations. This in turn supports the view that the current rise in obesity is due to increased food consumption, not decreased energy expenditure. It means we have more to learn about human physiology(生理学) and health, particularly in non-Western settings.

    "These results highlight the complexity of energy expenditure. It's not simply a function of physical activity," says Pontzer.” Our metabolic rates may be more a reflection of our shared evolutionary past than our diverse modern lifestyles."

(1)、According to the new research, hunter-gatherers consume _________.
A、the same energy as Westerners B、more energy than Westerners C、less energy than Westerners D、the same food as Westerners
(2)、How did the research team do the new research?
A、By comparing hiking distances. B、By identifying wild plants and game. C、By estimating daily energy expenditure. D、By measuring daily energy expenditure.
(3)、People have long assumed that _________.
A、the rise in obesity is due to increased food consumption B、decreased energy expenditure makes Westerners fat C、daily energy expenditure stays the same in history D、humans' habitual metabolic rates are unchanged
(4)、Which of the following can reflect our shared evolutionary past?
A、Our physiology activity. B、Our energy expenditure. C、Our metabolic rates. D、Our modern lifestyle.

    In 2006,Paul Letourneau of Worcester,Mass,lost his parents,his home and his pet dog.And that August,his life­long mild depression took a turn for the worse as he became suicidal(有自杀倾向的).

    “I said I didn't want to be alive anymore,”Letourneau,67,recalled telling his best friend.

    He and his friend had gone for a walk when Letourneau stopped and asked his friend about ways to die painlessly.His friend advised him to admit himself to a hospital.

    “When I went back home,physically,I was shaking so much-and emotionally,I couldn't stop,”Letourneau said,“I knew I had to get help.”

    For many men,it takes a lot more than feeling down to recognize that they are depressed and then step through the doors  of a hospital,or a friend's or relative's home to ask for help.Men who are depressed usually refuse to get appropriate treatment,depression experts and patients say.

    “When men get depressed,the depression can be quite severe,”said Dr.lan Cook,professor of psychiatry at the Geffen School of Medicine at UCLA.“The challenge is getting men to acknowledge that they're depressed.”

    Depression affects about 15 million people in the United States,according to the National Institutes of Mental Health,and men get depressed about half as often as women.

    “It's unclear how much of this is a reporting bias,”Cook  said.“The stigma(耻辱)issues are somewhat different for men than they are for women.”

    “Men intend to consider that asking for help is a sign of  weakness,but when they can't complete the task of bringing themselves to the Promised Land,they become at risk.” said  Steven Lappen,who was once a depression patient.

    I returned home the other night, tired. My husband asked me how my evening was, “Great.” I told him. I had spent 90 minutes in a gym with 10 Ping-Pong tables and all kinds of players, all playing a little ball over the net. By 9 pm, I was excited, tired, satisfied. I had beaten two young men half my age and lost battles against other competitors. To an observer, the night was common. To me, it was a lucky thing that I hadn't expected.

    I had taken up Ping-Pong during college, and in my 30s took more advanced lessons. However, a serious accident hurt my leg, which made me unable to take exercise. Months later, I tried to play Ping-Pong but my leg pained for a week. I put the game out of my mind.

When I was 53, one day my bad leg was working a little bit better. Could Ping-Pong be possible for me, now—in my condition, at my age? I tried to play Ping-Pong again

    Ping-Pong is a sport which requires endurance(耐力). Players need quick foot work and upper body movements to return balls, requiring faster response time than tennis.

    Playing Ping-Pong offers benefits for the brain. A study of 164 women aged 60 and older showed that Ping-Pong improved cognitive(认知)function more than dancing, walking or gymnastics. “The great thing about our sport is that it can be played by anyone,” said Jimmy Butler, a four-time national USA Table Tennis Association winner. “I see 90-year-olds and 10-year-olds.”

    Years passed and my endurance improved. People started to praise my shots. I won a game. Then I won agin. These days, I feel wonderful, I believe this sport is the fountain (源泉)of youth.

    When asked how technology might improve the lives of people with vision impairments (视力障碍), Joann Becker presented a misleadingly simple challenge. “Well,” the vision impairments tech specialist recalls saying. “I'd like to be able to find my bus slop through Be My Eyes”.

    Be My Eyes, which went live in 2015, establishes a direct video connection between visually impaired users and sighted volunteers. The assumption is simple: Many people who are blind don't need any actual assistance in completing their daily tasks, but merely need a little help.

    A sighted volunteer might be asked to help identify which of two cans contains tomatoes. In this case, the visually impaired user can cook a meal just fine on his/her own-all he/she needs is a quick confirmation that he/she has the correct can. The model appears to be working; more than 540,000 volunteers and nearly 40,000 people with low vision are registered on the app.

    “An elderly woman can now help a visually impaired technician set up his computer,” says founder Hans Wiberg, who has very low vision. “She doesn't need to know a thing about computers. She only needs to read what is presented on the screen. Then he can do the rest.”

    Early assistive technology centered on dedicated devices (专用设备), because of the niche market (缝隙市场), which sold for hundreds or even thousands of dollars. But the smartphone, multipurpose and near-universal, has completely changed the economy of scale.

    “There are larger market forces driving high-powered computation, high-quality engineering and high-quality battery management in the smartphone market than those in a specialty product,” says Aaron Steinfeld, a research professor at the Robotics Institute at Carnegie Mellon University.

    “The reality is, most sighted people don't know somebody who is blind.” Becker says. “They think the solutions that a blind person needs arc far more expansive, it turns out, they need to be. I think these apps are enabling sighted people to see that blind people just need some simple clues to help them do any number of things in their lives.”

    One day, on a small farm in Maine, a man sat in a barn watching a large grey spider spin a web. The man was E.B. White — or Andy, as he was called — who thought spiders were wonderful creatures. He thought that one day he might like to write a children's book about a spider.

    But writing was hard work for Andy. He had written many articles and essays and poems. He had also written one children's book, Stuart Little. But Andy could never just rush to turn an idea into an article or a book. He told his editor (编辑) that he needed to let his ideas ripen.

    So for years, Andy continued to think about writing a children's book about a spider. He did some of his best thinking while he wandered around his farm.

    Once while he was cleaning his barn, he found a spider's egg sac (卵囊). Andy wanted to see the eggs hatch. But he was scheduled to leave for a trip to New York City. So he found a small box and carefully placed the egg sacinside. When he got to his hotel, he put the box on the dresser. One morning he woke up, and there were hundreds of baby spiders rushing across the dresser!

    Years later, Andy finally began writing Charlotte's Web, the story of a spider named Charlotte and a pig named Wilbur. Andy created most of the book sitting by himself in the tiny boathouse of his farm.

    Sometimes he stopped writing and aimlessly drew pictures of spiders. Andy always said Charlotte's Web was more than just a children's story about animals. It was a timeless story about true friendship.

    All around the world, lawyers generate more hostility(敌视) than the members of any other profession-with the possible exception of journalism. But there are few places where clients have more grounds for complaint than America.

    During the decade before the economic crisis, spending on legal services in America grew twice as fast as inflation. The best lawyers made skyscrapers-full of money, tempting ever more students to pile into law schools. But most law graduates never get a big-firm job. Many of them instead become the kind of nuisance-lawsuit filer that makes the tort system a costly nightmare.

    There are many reasons for this. One is the excessive costs of a legal education. There is just one path for a lawyer in most American states: a four-year undergraduate degree in some unrelated subjects, then a three-year law degree at one of 200 law schools authorized by the American Bar Association and an expensive preparation for the bar exam. This leaves today's average law-school graduate with $100,000 of debt on top of undergraduate debts. Law-school debt means that they have to work extremely hard.

    Reforming the system would help both lawyers and their customers. Sensible ideas have been around for a long time, but the state-level bodies that govern the profession have been too conservative to implement(实施)them. One idea is to allow people to study law as an undergraduate degree. Another is to let students sit for the bar after only two years of law school. If the bar exam is truly a strict enough test for a would-be lawyer, those who can sit it earlier should be allowed to do so. Students who do not need the extra training could cut their debt mountain by a third. The other reason why costs are so high is the restrictive guild-like(行会) ownership structure of the business. Except in the District of Columbia, non-lawyers may not own any share of a law firm. This keeps fees high and innovation slow. There is pressure for change from within the profession, but opponents of change among the regulators insist that keeping outsiders out of a law firm isolates lawyers from the pressure to make money rather than serve clients ethically.

    In fact, allowing non-lawyers to own shares in law firms would reduce costs and improve services to customers, by encouraging law firms to use technology and to employ professional managers to focus on improving firms' efficiency. After all, other countries, such as Australia and Britain, have started liberalizing their legal professions. America should follow.
