1 . Teenagers’ fitness is now a major concern，and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong，and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers：“First，you need to find out your present level of fitness. Then you can design a programme that will help you become healthier.”

Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle.“Overweight”means that the person gets very little exercise and often has a serious weight problem. “Inactive” means that the person does not join in many physical activities，but is not seriously overweight.“Active”refers to people who take part in sports and other physical activities，but do not have a high fitness level.

According to Dr. Lopez，overweight teenagers should work out to keep healthy.“Ride a bike，play volleyball or basketball for a while，and go for a twenty­minute walk each day. All these will help to burn calories.”Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push­ups and sit­ups, starting with twenty of each a day.“Inactive people can take a little more exercise than overweight people because their bodies are stronger，”Dr. Lopez said. The same rule applies to active teenagers.

Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise，together with fifteen minutes a day spent on stretching and bending activities.“These are really important in order to prevent injuries,” Dr. Lopez said. Some weight­training and other body­strengthening exercises could also be planned in the programme in order to increase the person’s strength.

2 . All over the world people enjoy sports. Sports help to keep people healthy and happy, and to live longer.     1    They buy tickets or turn on their TVs to watch the games. Often they get very excited when their player or team wins.

    2    Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy!     3    Think how many lovers to skate or ski in Japan, Norway or Canada.

Some sports or game go back thousands of years, like running or jumping. Chinese Kungfu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet.     4    Water-skiing is one of the newest in the family of sports.

People from different countries may not be able to understand each other, but after a game together they often become good friends.     5    One learns to fight hard but fight fair, to win without pride and to lose with grace.

3 . There are many ways to travel within a city. We can walk, cycle or take a bus. But no matter which way we travel, we have to follow the route the city planners made for us.

Parkour (跑酷) practitioners, however, see the city in a completely different way. To them, there are no fixed routes. There are no walls and no stairs — since they jump, climb, roll and crawl to move across, through, over and under anything that they find in their path. The city is their playground.

The International Gymnastics Federation (FIG) has noticed that this activity is attracting more and more people to it — there are 100,000 people taking part in parkour today in the UK alone, according to The Guardian — and how it is helpful for people to be much stronger: It trains coordination (协调) and balance. So, the organization is thinking about recognizing parkour as a new sport and adding it to the 2024 Olympics.

However, parkour practitioners themselves don’t seem to be happy with the idea. They see parkour as “a lifestyle”, wrote the website Next Sport Star. “It’s a competition against the conditions rather than just a sport.”

Indeed, many do parkour just to “escape the daily routine and experience the city in different ways”, wrote reporter Oli Mould on The Conversation. They see parkour as a way to express themselves through relaxing moves and creative routes while freeing themselves from the pressure.

It’s great that the FIG wants to develop a new sport and stay close to a new cultural form. But it would be greater if they knew that not everything in life is a competition.

1. How do the parkour practitioners travel within the city?

A．By following fixed routes.

B．By cycling.

C．By using their own ways.

D．By taking a bus.

4. What is the writer’s attitude toward parkour?

A．Negative.	B．Unconcerned.
C．Worried.	D．Objective.

6 . Is It a Healthy Interest?

The Guinness Book of World Records describes Ranulph Fiennes as the world’s greatest living explorer. His journeys include the first polar circumnavigation (极地环行) and the first unsupported crossing of the Antarctic continent on foot. So when he suffered a heart attack, it came as something of a surprise.

Exercise is highly beneficial as it reduces both the pulse (脉搏) rate and the blood pressure so reducing stress on the heart as it brings blood round the body. It also helps to keep the artery (动脉) walls more elastic (有弹性的).

But can you push yourself too much? On the subject of exercise, it is good to take several parts of “moderate” exercise a week，which is a little more than quick walking. “We need to be careful when we’re doing extreme sports,” says expert Len Almond. “Extreme stress can make almost impossible demands on the body’s ability to recover. The stress of extreme sports forces biochemical changes in the body, and the physical response to that kind of activity will be too extreme.”

We all know how the Olympics began. The man who ran 26 miles from the town of Marathon to Athens with news of a victory died as soon as he arrived，and the cause of his sudden death might be the heart attack. Further research was done by scientists. They studied cyclists (自行车运动员) on a race that covers 230km with a height change of 5,500m. They were interested in one particular enzyme (酶), high concentrations of which are found in those who have suffered a heart attack. The scientists found that levels of this chemical increased in most of the cyclists who completed the race. The largest increases were seen in the fastest cyclists who had trained the hardest.

Most of us will never put our bodies to such extreme sports. But if, when you hear about someone like Fiennes，you ask whether exercise is worth it. I advise you to consider your own condition. Personally, I agree with the saying: “Run not to add years to your life but to add life to your years.”

3. Why is the research on the cyclists mentioned in Paragraph 4?

A．To suggest a different area of research.

B．To support the activity of taking part in sports.

C．To explain the effect of a height change on cyclists.

D．To prove that extreme sports may cause heart attacks.

4. The author believes that exercise_______.

A．helps you have a regular life	B．adds years to your life
C．should be done in moderation	D．will be worth the effort

7 . One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.    1    .

In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.    2     This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least―but still ran. ‘‘Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.

The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do.     3     But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”

    4     Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎症), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.

    5     Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.

A．People may no longer hunt wild animals for their next meal.

B．The physical demands of running affect our body in a beneficial way.

C．Some people run to prevent disease, and others run because it makes them feel better.

D．Runners were 27% less likely to die for any reason, compared with nonrunners.

E．But researchers point out, to infer something like that, they need the whole population measured.

F．But new research suggests people may be able to get life-lengthening benefits by running for far less time.

G．The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying.

8 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your choice of sport might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(高尔夫球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortages in some local areas.

In fact, there are many environment friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a pair of good shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk can regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and control your weight better.

Whatever sport you take up, you can make it greener by using environment friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

9 . A study has found that a lifetime of regular exercise and activity can slow down the aging process (衰老过程). Researchers say that getting older should not necessarily mean becoming more weak or sick. Their research shows that a devotion to a life of movement and exercise may help us live not only longer, but also healthier.

For their study, the researchers looked at two groups. The first group was made up of 125 non-professional cyclists between the ages of 55 to 79. This group included 84 healthy men and 41 healthy women. We will call this group the “cyclists”.

Researchers then found 130 people to make up a second group. Within this group, 75 people were aged from 57 to 80. The other 55 were between the ages of 20 and 36. The people in this group were also healthy, but they did not exercise regularly. We will call this group the “non-exercisers”. Smokers, heavy drinkers of alcohol and people with other health issues were not included in the study.

Then, researchers gave both groups a series of tests. They tested their muscle mass (肌肉质量), muscular strength, percentage of body fat and the strength of their immune (免疫的) systems. Then the researchers compared the results of the two groups.

Results showed that the cyclists did not experience body changes usually regarded as a normal aging process. For example, they did not lose muscle mass or muscular strength. Also, their body fat did not increase with age.

The researchers also found something they had not expected. The study showed that the immune systems of the cyclists did not age either.

The researchers advise us all to find an exercise that we like in our lives.

B．Take an Exercise, the Harder, the Better

C．Cycling Is the Best Way to Prevent Aging

D．A Lifetime of Exercise Slows Aging Process

10 . It is not as simple as opening the door and hitting the track in winter. There are a few things you can do to ensure you are getting the most out of your run, and, importantly, not doing more harm than good.

Warm up, cool down

    1     Your muscles need some time to warm up when it's cold, so take it easy when you set off and do a few stretches （伸展）once you're finished.

Drink water

You might not feel hot, but that's because sweat evaporates （蒸发）more quickly into the chilly, dry air. So be sure to drink water before, during and after cold-weather workouts.     2     A belt bottle conveniently attaches to your waist so you don't have to carry it and can have a drink whenever you feel like it・

    3    

Running in cotton is a bad idea. Wear thin, breathable layers of synthetic （合成 的)）clothing that help protect you from the wind and snow, but still let out heat and moisture （水分）.Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie （无边小便帽）, and gloves so your circulatory system can distribute warm blood to the rest of your body.     4    

Run into the wind

    5     . Obviously, it will be an easier passage home with some extra help from Mother Nature. But, more importantly, you won't have the wind in your face for the second half of your run, when you are more likely to be sweating and catch a chill.

A．Dress right

B．Keep warm.

C．Don't go too fast, too soon

D．Start and finish in the same way.

E．Don't wait to drink water until you feel thirsty.

F．Head out into the wind and come home with it at your back

G．On really cold days, wear a mask or scarf over your mouth to protect your face.
