    Are you sick of going to bed late and waking up tired? Then grab your hiking boots and a tent. A new study suggests that camping in the great outdoors for a couple of days can reset your body clock and help you get more sleep.

    The body clock is an internal system that tells our bodies when it's time to go to sleep and when it's time to wake up. Scientists track this clock by measuring the amount of melatonin (褪黑激素) circulating in a person's blood at any given time.

    In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high through the night, and then settle back down when it's time to wake up.

    In our modern society, however, most of us stay up many hours past sunset and would probably sleep in many hours after sunrise if we could. And the trouble is, your melatonin levels may still be high when your alarm clock goes off in the morning, which leads to fatigue. It may also have other health consequences as well, such as diabetes (糖尿病), overweight and heart disease.

    Professor Kenneth Wright of the University of Colorado in the US wanted to see if our body clocks can be reset by a short stay in nature. His team recruited (招募) fourteen physically active volunteers in their 20s and 30s. Nine went on a weekend camping trip, while the other five stayed home. At the end of the weekend, the researchers reported that in just two days, the campers' body clocks had shifted so that their melatonin levels began to rise more than an hour earlier than they did before they left on the trip. By contrast, the body clocks of the group that stayed home shifted even later over the course of the weekend.

    “This tells us we can reset our clocks fast,” Wright said.

    Therefore, if you want to change your sleep patterns you could try to increase your exposure to natural light during the day and decrease the amount of artificial light you see at night. And if that doesn't work,there's always camping.

(1)、The underlined word “fatigue” in Paragraph 4 probably means ________.
A、excitement B、tiredness C、relief D、disappointment
(2)、What did Wright's team discover from their experiment?
A、Those staying outdoors reset the clock inside their bodies over a short period. B、The body clocks of the two groups didn't show much difference. C、The body clocks of those who stayed at home remained the same. D、Changes to the body clock don't necessarily affect melatonin levels in our bodies.
(3)、According to the passage, to change our sleeping habit, we'd better ________.
A、stay home to reset our body clock and get more sleep B、stay up late long past sunset and sleep long after sunrise C、get exposed to more natural light but less artificial light D、try to reduce melatonin levels as much as possible at night
(4)、What is the author's main purpose of writing the passage?
A、To inform us of a possible way to adjust the body clock. B、To explain how a lack of sleep is bad for our health. C、To analyze how the body clock influences our sleeping habits. D、To explore how the body clock is connected with melatonin levels.

    "Everybody is a genius.But if you judge a fish by its ability to climb a tree,it will live its whole life believing that it is stupid."—Albert Einstein

    If you have a kid with special needs in the school system,chances are you have come across that saying hanging on a classroom wall.My five-year-old daughter Syona has cerebral palsy(脑瘫)and it means,combined with her communication and sight problems,that normal standard isn't always an accurate measure of her abilities.

    By now you have probably heard about Chris Ulmer,the 26-yearold teacher in Jacksonville,Florida,who starts his special education class by calling up each student individually to give them much admiration and a high-five.I couldn't help but be reminded of Syona's teacher and how she supports each kid in a very similar way.Ulmer recently shared a video of his teaching experience."I have seen their confidence increase rapidly."he said.All I could think was: how lucky these students are to have such good teachers.

    Syona's teacher has an attitude that can best be summarized in one word: awesome.Her teacher doesn't focus on what can't be done—she focuses on what can be done.Over the past several months,my husband Dilip and I have seen Syona's confidence increase tenfold.She uses words she wouldn't have thought of using before.She recently told me about her classmate's trip to Ecuador and was very proud when I understood her on the first try.

    I actually wonder what the influence would be if we did something similar to what Ulmer does with his students in our home.We've recently started our day by reminding each other of the good qualities we all possess.If we are reminded of our strengths on a regular basis,we will become increasingly confident about progress and success.

    Subject: My school

Hi, Li Zijun,

    Thanks very much for your email. I really enjoyed reading it. I think we have a lot in common. I wonder if our school life is similar too.

    I go to a big high school in Sydney called Maylands High School. There are about 1000 students and 80 teachers. My class has 25 students in it, which is normal for a Year 11 class. In the junior school there are about 30 students in a class.

    In the senior high school we have lots of subjects to choose from, like maths, physics, chemistry, biology, history, German, law, geography, software design, graphic arts and media studies. (Different schools sometime have different optional subjects.) English is a must for everyone and we have to do least three other subjects in Year 11 and 12. At the end of Year 12 we sit for a public exam called the High School Certificate.

    As well as school subjects, most of us do other activities at school such as playing a sport, singing in the choir or playing in the school band. We can also belong to clubs, such as the drama club, the chess club and the debating society.

    We have a lot of homework to do in senior school to prepare for our exam, so unless I have basketball practice, I usually go straight home and start studying. I arrive home about 4 pm, make myself a snack and work till 6 pm. Then I help the family to make dinner and we all eat together. I'm usually back in my room studying by 8 pm. I stop at about 10 o'clock and watch TV or read a book for half an hour to relax. On Saturdays, I usually go out with my family or with friends and I sleep in till late on Sunday morning. Then it's back to the books on Sunday afternoon.

    How about you? What's your school life like? Do you have a lot of homework? What do you do to relax when you're not studying? I'm looking forward to finding out.

    There is no doubt e-commerce is growing, and it will continue to grow. However, physical stores would not die as a result of the rise of e-commerce, at least not in the near future. The idea that e-commerce is taking over physical stores has already misguided many people. Physical stores are far from vanishing (消逝), and there are some solid reasons for it.

    The projections for online spending is optimistic with 150 billion expected to be spent in the coming three years, yet we are also expecting 300 billion in spending at physical stores in the same duration. Do you still think that physical-store shopping is too small to sustain (支撑) the e-commerce blow?

    Even though consumers are staying away from physical stores that follow older concepts, yet we are seeing the rise of fresh concept stores all around the US. We are seeing innovative and attractive success stories of physical stores, ranging from clothes stores to restaurants to health spas. It would be easy to assume that this trend will continue.

    Indeed, many shopping malls are dying, yet there are still some shopping centers that are performing well. You can see this for yourself by visiting shopping malls near you. What I want to emphasize here is that not all shopping centers are made equal, just like not all e-commerce retailers (零售商) are made equal. Both shopping malls and e-commerce sites can lose business if they fail to maintain productivity through improvements and innovations. When you visit shopping centers that are serious about their business, you would see their shops and parking lots packed.

    On the other hand, even e-tailers like Amazon have experimented with pop-up shopping concepts. It is important to bear in mind that consumers prefer face-to-face interactions instead of online interactions during shopping, meaning that physical stores are going to stay there.

    Still, e-commerce retailers are seeing all of their excitement disappear as they settle the sales tax problem associated with e-tailing. As of now, five states of America have already imposed sales tax on purchases through e-commerce sites, and e-tailers in those states have already witnessed 6 to 12 percent decrease in sales.

    This reinforces the fact that physical stores are here to stay, and if you are still undervaluing their growth, you are omitting (省略) a huge chunk of the retail representation.

    The month of March was a milestone for supporters of renewable energy in the U.S. For the first time, wind and solar power accounted for more than 10% of the country's electricity—up from less than 1% at the turn of the century. And total wind and solar power-plant capacity(发电量) is expected to grow more than 30% over the course of this year and next, according to the Energy Information Administration.

    Such forecasts have led many scientists and policymakers to think that moving a large part of the nation's power supply to renewable sources—as cities from Miami Beach to Salt Lake City have promised to do—may not be as far-fetched as once thought. But like any debate, there are dissenters, including those inside the federal government. Their argument is that the nation demands an uninterrupted supply of electricity and cannot count on sun, wind and natural gas to provide it. “You need solid hydrocarbons(固体碳氢化合物) on-site for rising peak demand,” Environmental Protection Agency administrator Scott Pruitt said on Fox Business in May, referring to the importance of coal as a power source.

    Many experts say the government's concern fails to account for how the power grid(电网) has improved in recent decades. Utility companies(公共事业公司) have developed innovative ways to move electricity from place to place to account for variation in weather. Battery technology can store power for use when renewable sources cannot operate, meaning solar power can be used on days when the sun doesn't shine. And the nation's vast supply of natural gas can be turned into usable energy with the flick of a switch.

    “I don't think 5 or 10 years ago I'd be comfortable telling you we could not sacrifice reliability when we're going to have 35% of our energy come from wind,” said Ben Fowke, CEO of the utility company Xcel Energy, at a recent conference. “I'm telling you, I'm very comfortable with that today.”

    Indeed, many parts of the country are already close to that reality. In some regions, like Iowa and Kansas, renewable energy supplies more than 25% of the electricity. The market has shifted so far in favor of natural gas and renewable energy that even the most concerted federal effort is unlikely to stop its growth. Any attempt to slow the growth of wind and solar will face strong pushback. “If anyone wants to do away with it,” Republican Senator Chuck Grassley told Yahoo News of the federal government's potential cuts to wind energy, “he'll do it over my dead body.”

    But the federal government could slow the acceleration—and with billions of dollars in private and public investments at risk, the pace of change matters. Decisions made today will shape the future of the nation's energy grid for decades to come.
