    Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

    But while it's long been believed that endorphins (脑内啡)—chemicals in the body that cause happiness — are behind the so-called “runner's high”,a study suggested that there may be more to this phenomenon than we previously knew.

    According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素)may actually be responsible for this familiar great feeling.

    To test this theory, the scientists turned to mice.

    Both mice and humans release high levels of endorphins and endocannabinoids after exercise, along with many other chemicals. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety.

    But after being given a drug to block their endorphins the change. However, when their endocannabinoids were block with a different drug, their runner's high symptoms seemed to fade.

    “The long-held notion of endorphins being responsible for the runner's high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,”Patrick Lucas Austin wrote on science blog Lifchacker.

    Similar studies are yet to be carried out on humans, but it's already well known that exercise is a highly effective way to get rid of stress or anxiety.

    The UK's National Health Service even prescribes (开药方)exercise to patients who are suffering from depression.

    “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can boost your mood if you have depression, and it's especially useful for people with mild to moderate (中等的)depression,” it wrote on its website.

    It seems like nothing can beat that feeling we get after a good workout, even if we don t fully understand where it comes from. At least if we're feeling down, we know that all we have to do is put on our running shoes.

(1)、What did scientists from German universities recently discover?
A、Working out is a highly effective way to treat depression. B、The runner's high could be caused by endocannabinoids. C、Endorphins may contribute to one's high spirits after running. D、The level of endorphins and endocannabinoids could affect one's mood.

A、find what reduces the runner's high symptoms B、see the specific symptoms of the runner's high C、identify what is responsible for the runner's high D、test what influences the level of endocannabinoids released
(3)、The underlined word “notion” in Paragraph 7 has the closest meaning to      .
A、effect B、goal C、question D、belief
(4)、According to the UK's National Health Service, regular workouts       .
A、are the best way to treat depression B、can help ease depression symptoms C、only work for those with serious depression D、can help people completely recover from depression

Chopsticks

    Right now, millions of people are digging into their food with two sticks that have school the test of time as a utensil(烹调用具)for humans. But what's so special about them? {#blank#}1{#/blank#} Personally, I think they teach us the importance of:

    {#blank#}2{#/blank#} 

    If you're ever tried using them, you know that you can't get what you want by just randomly stabbing at the plate. To be able to get what you want, you have to aim for it. There's no way you can pick up everything in one go. Know what you want, and just do it. {#blank#}3{#/blank#} 

    Practice

    Using chopsticks doesn't come naturally. You can't learn to use them by just reading about them. {#blank#}4{#/blank#} It is the same with the real life. You can read as much as you like about all the things you want to do, but it will just amount to dreams and theory if you don't try actually doing it.

    Slowing Down

    {#blank#}5{#/blank#} Why? Because it allows your stomach to tell your brain you're full before you overeat. Eating with chopsticks is a slower process, but that is not necessarily a bad thing. Sometimes we need to slow down and take things one step at a time, so that we have time to think and realize that we don't have to keep charging full speed through life.

A. Aim

B. Motivation

C. What can we learn from them?

D. You have to practice using them

E. Those who eat too fast were less successful at losing weight

F. Sometimes, a little bit of focus makes the difference between failure and success

G. A common health tip is to try to eat with chopsticks when you can

    City Life in Thailand is much like city life in the United States. People live in tall buildings or in houses close together. But outside the cities, life is different. People usually live on farms far apart from one another. They grow their own food or buy fresh food almost every day at the market. But the market is not in a building. It is a floating market located on a river.

    Lamai and her family live on a farm. They grow fruits and vegetables and sell them at the market each day. Long before the sun comes up, Lamai and her brother help their parents. They pick out fruits and vegetables and clean them. Then they load everything into a long boat.

    Their boat is ready by about 6:00 a.m. Lamai and her mother row to the closest floating market. On the way the water is still and peaceful. Lamai sees the bright sun beginning to shine.

    Soon Lamai hears laughing and yelling in the distance. Her mother rows the boat around a corner. Suddenly they are at the floating market. Hundreds of boats are gathered at a wide place in the river. Lamai's mother is selling bananas and ripe tomatoes today. For Lamai a trip to the market is more than just a chance to sell or buy something. It is a chance for her to talk to her friends.

    Today Lamai sees her friend Suki. He is helping his mother prepare meals in their boat. Lamai loves the smell of the fried bananas Suki's mother is making. Lamai's mother rows over to buy a late breakfast. As Lamai eats, she and Suki talk about their summer plans.

    At around 11:00 a.m. people begin to go home. She is sleepy from waking up so early. Her mother has sold most of what they brought to the market. The will leave the market with less food in their boat but with more money for Lamai's family.

    Who cares if people think wrongly that the Internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes?

    It would not matter if these misjudgments were just a matter of people's opinions. However, they have real impacts, as they result in misguided use of scarce resources.

    The fascination with the ICT (Information and Communication Technology) revolution, represented by the Internet, has made some rich countries wrongly conclude that making things is so "yesterday" that they should try to live on ideas. This belief in "post-industrial society" has led those countries to neglect their manufacturing sector (制造业) with negative consequences for their economies.

    Even more worryingly, the fascination with the Internet by people in rich countries has moved the international community to worry about the "digital divide" between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and Internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people's lives more than giving every child a laptop computer or setting up Internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.

    In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a "borderless world". As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on cross-border flows of capital, labour and goods, with poor results.

    Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under valuation of what has already become common, can, and has, led us in all sorts of wrong directions.

Freshmen at Central Valley High in Ceres had a busy week of good deeds, tied to Pay It Forward Day, April 30, and an urge to show the world that teens can be awesome.

Kids in Success 101 spent first period making sandwiches for the homeless. The classes, taught by Natalie Rowell and Becky Lynch, got to hand 200 bagged sandwiches to the charity giving out the food. "They got to really see what an impact they had. It was inspiring and heartwarming," Rowell said. Besides, students also made blankets to send to soldiers, and created 45 flower arrangements for senior people at the Hale Aloha Home in Ceres. "They were nervous going into it. But when they saw how happy the elderly were, the reality of what they did really surfaced," Rowell said.

Rowell said she liked working with children. get to see how they learn. "It's different from how we learn, but we're kind of the same because they struggle in some of the subjects that we find hard as well."

Success 101 was tailor-made for students with that kind of insight. The first-period class includes study help, speakers on teen subjects and an overall focus on looking past high school, figuring out the steps to create their future. "Some kids need that little push. In this class, that's what we do, we give them that little push," Lynch added. "Success would be beneficial for all ninth-grade students. Since the start of the year, I really see a change in them."

Raquel Alfaro, a teen participant who worked with the younger kids, likes the Pay It Forward idea. "This helps us show adults, and also kids, that we're doing something different and that we're not as mean and selfish as they think we are," Alfaro said.
