2 . 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 (内啡肽) —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. 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 mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ 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 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 improve your mood if you have depression, and its 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 to put on our running shoes.

3 . The Price of a Dream

I grew up poor. We had little money, but plenty of love and attention. I understood that no matter how poor a person was, they could still afford a dream. My dream was athletics.

By the time I was sixteen, I was good at baseball and football. My high school coach was Ollie Jarvis. He not only believed in me, but taught me the difference between having a dream and showing conviction (信念).

One summer a friend recommended me for a summer job. This meant a chance for money in my pocket — cash for dates with girls, certainly, money for a new bike and new clothes, and the start of savings for a house for my mother.

Then I realized I would have to give up summer baseball to handle the work schedule, and that meant I would have to tell Coach Jarvis I wouldn’t be playing. I was afraid of this, but my mother said, “If you make your bed, you have to lie in it.” 

When I told Coach Jarvis, he was as mad as I expected him to be. “Your playing days are limited. You can’t afford to waste them,” he said.

I stood before him with my head hanging, trying to think of the words that would explain to him why I dream of buying my mom a house.

“How much are you going to make at this job, son?” he demanded.

“Three point twenty-five an hour,” I replied.

“Well,” he asked, “is $3. 25 an hour the price of a dream?”

That question exposed the difference between wanting something right now and having a goal. I devoted myself to sports that summer, and within the year I was drafted by the Pittsburgh Pirates to play rookie-league ball, and offered a $20, 000 contract. I signed with the Denver Broncos in 1984 for $1.7 million, and bought my mother my dream house.

4 . Parents whose children show a special interest in a sport feel very difficult to make a decision about their children’s careers. Should they allow their children to train to become top sports men or women? For many children it means starting schoolwork very young, and going out with friends and other interests have to take a second place. It’s very difficult to explain to a young child why he or she has to train five hours a day, even at the weekend, when most of his or her friends are playing.

Another problem is of course money. In many countries money for training is available from government for the best young sportsmen and women. If this help can not be given, it means that it is the parents who have to find the time and the money to support their child’s development and sports clothes, transport to competitions, special equipment, etc.

Many parents are worried that it is dangerous to start serious training in a sport at an early age. Some doctors agree that young muscles may be damaged by training before they are properly developed. Professional(专业的) trainers however, believe that it is only by training young that you can reach the top as a successful sports person. It is clear that very few people do reach the top, and both parents and children should be prepared for failure even after many years of training.

6 . For the rest of March, a disease will sweep across the US. It will keep kids home from school.       1         Employees will suddenly lose their ability to concentrate.

The disease, known as “March Madness”， refers to the yearly 65­team US men's college basketball tournament (锦标赛).       2         Teams compete against each other in a single­elimination (单局淘汰) tournament that eventually crowns a national champion.

Nearly 20 million Americans will find themselves prisoners of basketball festival madness. The fun comes partly from guessing the winners for every game. Friends compete against friends.           3         Colleagues against bosses.

Big­name schools are usually favored to advance into the tournament. But each year there are dark horses from little­known universities.

This adds to the madness. Watching a team from a school with 3,000 students beat a team from a school with 30,000, for many Americans, is an exciting experience. Two years ago, the little­known George Mason University was one of the final four teams.     4    

College basketball players are not paid, so the game is more about making a name for their university and themselves.     5     About $4 billion will be spent gambling (赌) on the event. According to Media Life magazine, the event will bring in $500 million in advertising income this year, topping the post－ season income of every US professional league, including that of the NBA.

A．Husbands against wives.

B．The players will go all out for the games.

C．But that doesn't mean money isn't involved.

D．College students will ignore piles of homework.

F．It begins on March 15 and lasts through the beginning of April.

G．Many people had never even heard of the university before the tournament.

7 . Have you ever wondered how your favorite NBA team received its famous name? All NBA teams have an interesting story or a history behind their names. Some of the names reflected the city’s culture or history, others came from previous owners and many were selected through “Name the Team” contests.

For teams like the Los Angeles Lakers and the Utah Jazz, the names were not always a reflection of the city. Even though Los Angeles has no lakes, the Lakers name has been a city treasure for almost 40 years. Before going to Los Angeles, the team originated in Minneapolis, Minnesota. In1947, team officials changed the name to the Lakers to reflect the Minnesota State’s nickname, “Land of 10,000 Lakes”. The team name went unchanged after moving to Los Angeles in1960.

Because the Utah’s team originated in New Orleans, Louisiana, it was called the Jazz. In 1974, New Orleans club officials chose the name to represent the city for its reputation as the “Jazz Capital of the World”. The name stayed with the team even after they found a new home in Salt Lake City, Utah in 1979.

The original owner of the Chicago Bulls, Richard Klein, named the team the Bulls. He picked the name because a fighting bull is relentless and never quits. Klein, who founded the club in 1966, believed these qualities were necessary for a championship team and hoped his Chicago athletes would live up to the team name. The Bulls, the winner of the six NBA championships, has definitely followed the belief.

In 1967, the Indiana Pacers selected their team name in a different way from most other teams. Their decision was based on what they wanted to achieve in the NBA. Team officials chose the Pacers name because the organization wanted to set the “pace” in professional basketball.

9 . The beach may seem like an inviting place to run on a cool summer morning, but is running on the sand good for your body? It can be, but it’s important to be aware of the challenges that some beach runners experience before you get ready.

Running on the beach can be a good thing. It’s certainly different from running on a track or a pavement. For starters, sand can be a challenge because it has an uneven(不平坦的) surface. As you push off, you’re going to lose some of your push as the sand moves. So, you’re not going to be able to push yourself forward as you would on a track or a pavement. But this unevenness has an upside: It gives your body an extra workout, forcing you to exercise muscles that don’t get as much use during runs on firm surfaces. For example, your feet, ankles and lower back might feel sorer and more tired than usual after a beach run just because the surface is constantly moving and changing step to step.

You also might feel sore afterward because beaches tend to slope (倾斜) down to the water. If you’re going for a long run on the beach, you might notice that one side of your body might feel sorer because you’re putting more pressure on it due to the slope.

Some beach runners prefer to run barefoot-- not wearing anything on feet. However, if you’re not used to barefoot running, start slowly and don’t run long distances at first. That’s because running barefoot uses more different muscles than running with shoes does, and it’s important to strengthen these muscles and adapt your feet. If you want to run barefoot and as long as you run carefully enough into it, go for it!

Running on the sand can be a smart choice for you, because running on softer ground surfaces can reduce muscle damage.

1. Why is it difficult to run on the beach for starters? ________

A．The soft surface makes people fall over easily.

B．It’s hard to keep one’s balance on its hard surface.

B．Critical.

C．Doubtful.

D．Uncaring.

4. The passage can probably be found in ________.

A．a primary school textbook	B．a tourist guide

10 . Benefits of Sports

Doing sports is a physical, mental and social adventure. It’s a great way for children to take a break from studies and release extra energy. It also helps them lead fuller and happier lives as regular sports have proven beneficial to overall well-being.

The physical benefits of doing sports are probably the most obvious. Regardless of your fitness level when you start playing sports, you’ll notice an increase in your overall fitness once you’re involved.     1     Basketball players focus on strength training; football players work on speed while track athletes train through longer runs. The training process helps promote physical fitness and performances in competitions.

    2     Playing sports also contributes to mental health, helping to increase confidence and self-worth. A pat on the back, a high five from a teammate, or a handshake after a match really boosts a child’s confidence. Words of praise and encouragement from the coach, parents and other players raise self-worth.     3     So after a game, it’s a better idea to ask “Did you enjoy the game?” rather than “Did you win?”

Children who participate in sports might also benefit from the social aspect, feeling part of a group, building up responsibility and leadership.     4     Teamwork involves both being dependable as a teammate and learning to rely on your teammates to achieve a positive outcome. Teamwork breeds responsibility and challenges you to be responsible for your actions. Being part of a team gives you an opportunity to be a leader.

Discipline is another social advantage. Most organized sports require a strict training and practice schedule. As a student-athlete, you need to balance studies and athletics.     5    

There is no shortage of reasons to find a sport to get involved in. Are you ready to go? Pick one and get moving!

A．It’s not just your body that benefits from sports.

B．Therefore, playing sports is going to make you more fit.

C．But remember, a child’s self-worth should not be distinguished by victory or loss.

D．If you play group sports, you’ll be part of a team that takes direction from a coach.

E．Nearly every sport requires physical activities and the competitive skills.

F．Among these, learning how to function as part of a team is the most important advantage.

G．Only with strict discipline can you be successful both in the classroom and in the sports field.
