1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

3 . On a bright early summer morning, many young swimmers gather at a local swimming pool in the state of Maryland. They are members of a competitive summer swim team, and that’s a regular part of their daily life. As they train and cut seconds off their times, which makes them closer to the championship in the following large-scale (大规模的) competitions, they are getting lots of physical exercise and vitamin D from the sun. However, the benefits of belonging to a sports team are not just honor or health related. You can learn useful life skills.

Paul Waas, coach of the swim team, explains, “The discipline (自制力) comes into play when you’re talking about concentrating on the details that your coaches are saying as it makes you faster rather than going up and down the pool the same way you have every time. When you focus on what you’re doing right and what you can do better, then you’ll see the improvement.”

Besides, there is also responsibility, goals and workings within a group. Again, here is Coach Waas. “It’s really great! It’s so fun to watch from year to year. I’ve had kids who as 7-year-olds on the team could barely pay attention in practice and were only interested in who was going first. Now they’ve come back as 8-year-olds, having set some goals and having things that they want to achieve. These skills can help them a lot.”

But playing the sports is not without harm. Some can be hard on the body. Young athletes suffer serious injuries that follow them into adulthood. Coach Waas says that in fact, swimming is different from most others. First, it poses a lower risk of injury. The second one relates to how swim teams are structured. Actually, children are not the only ones who can benefit. Adults can also benefit from team sports.

1. Why do the swimmers gather at a swimming pool in the early morning?

A．To obtain vitamin D from the sun.	B．To build practical skills for future.
C．To join in a large-scale competitive.	D．To carry out their routine practice.

2. What do Paul Waas’ words imply in paragraph 2?

A．Swimmers should concentrate on details.

B．Members get disciplined and focused in the team.

C．Coaches play a key role in layers’ improvement.

D．Most swimmers enjoy sinning in the same way.

3. What happens to the kids after a year’s training?

A．They are more aware of what to do.	B．They pay less attention to training.
C．They devote more time to practice.	D．They care more about who goes first.

4. What does the author want to convey in the text?

A．Exercise benefits everyone.	B．Swimming is better than other sports.
C．Team sports teach life lessons.	D．Physical exercise should be a habit.

4 . Water skiing

Water skiing is an exciting water sport that can be a ton of fun. You will get to have a happy and joyful adventure every time you go out on the water.     1     However, once you start, water skiing is a sport you can enjoy whenever you have a boat and enough flat water.

    2     Every water skier needs water skis—these are different from snow skis and they also differ depending on the size of the skier and the experience level of the skier.     3     You will need to find at least two people to go with you on your water skiing adventure. You and everyone you go with will have more fun if the friends you go with also want to water ski. You need a boat, naturally.     4    

For your first time water skiing, you may want to either take a lesson from an expert or find a friend that has experience and is willing to teach you.     5     The observer rides in the boat, but watches the water skier for any signals and helps the driver know when to start and stop.

A．It’s no hard task to learn.

B．It takes a little patience to learn.

C．Of course, no one can water ski alone.

D．Once prepared, a skier can start the game on his own.

E．You will also need a water skiing cable and a life jacket.

F．Before you start water skiing, there are a few supplies you’ll need.

G．Of your two helpers, you need one to drive the boat and one to observe.

5 . 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.

6 . We all know that regular exercise is vitally important for both a healthy mind and body. Research has shown that just five minutes of exercise in a “green space” can help people to keep mentally healthy.

Let’s take a look at some ways to get close to nature and make them a part of your regular exercise routine.

Get on your bike

Cycling is a cheap, easy and fun way to get some good exercise in the outdoors. Try leaving your car at home and cycling to work one day, if that’s possible. Or get the family together and go on a weekend bike ride. Check out the local cycle paths before you go, and plan a safe route. Make sure you take some healthy snacks with you to keep your energy levels up.

Try some outdoor yoga

Practising yoga can be great for reducing anxiety and aiding relaxation, so why not take your yoga mat and try out some asanas (yoga postures) in the open air? Yoga is great for stretching tight muscles and increasing flexibility as well as improving mobility, control and breathing. Why not finish your practice with some quiet meditation to further calm the mind?

Go running

Instead of spending hours on the treadmill(跑步机), grab a friend and go off for a jog around your local park, or some nature trails. If you are used to running on a treadmill, you may find it harder at first, so make sure you have some good, supportive running shoes. You could also find out where your nearest Parkrun is. They are open to everyone, free, and are safe and easy to take part in.

Join a conservation(保护) group

Joining a conservation group is a great way of keeping fit while helping the world around you. Do some research into what’s going on in your local area and you could find yourself helping to plant trees, clear up rivers and so on. You never know it could lead to new friendships, as well as the knowledge that you are doing something productive for your local area!

1. If you want to cycle with your family, you’d better __________.

A．have a healthy body	B．check the bikes carefully
C．learn some survival skills	D．make good preparations for it

2. What’s the advantage of outdoor yoga according to the text?

A．Getting closer to nature.	B．Feeling relaxed or peaceful.
C．Keeping active and energetic.	D．Building up people’s bodies.

3. What problem do some people have if they want to run around their local park?

A．It takes them some time to get used to it.	B．It needs some patience to continue.
C．It makes them lose interest in running.	D．It leads them to fall behind their friends.

7 . Humans were made for walking. With our upright posture and strong leg muscles, our bodies were actually designed with walking in mind which makes it such perfect exercise. It’s kind to our bodies and great for our waistlines.     1    

Maybe you already love to walk, but you’re getting tired of tracing the same old route day after day, or maybe you’re new to walking and aren’t sure how to get started.     2    Ask yourself, what do you want to get out of walking aside from the health benefits? Do you want to meet other people? See new places? Get out into the countryside or explore a new city? Knowing your goals will help you decide on the type of walk you want to do.

If making friends and socializing is your goal, call up your friends and schedule walks with them.    3     Many malls have groups that come every day, or every weekend, to “walk the mall.” These groups are always happy to include one more walker!

    4    Many large cities have incredible gardens and parks that include quiet walking trails getting you off the beaten path. Thanks to the Rails to Trails program, railways across the country are being transformed into scenic walking paths that are a perfect way to seek calmness.

From the benefits to your heart to your overall happiness, walking is just plain good for you.    5    It’s a fantastic way to get to know a place by the power of your own two feet.

A．Headed to a new city?

B．This month, pick up a map and start walking.

C．Ask your friends where they like to walk and just go there.

D．Either way, it's time to accept the idea of walking with a purpose.

E．And best of all, it’s a great way to see new things and meet new people!

F．Recently, science has proved that walking is good for your body shape.

G．If you're after walking alone, ask about local hikes that get you out of town and into the countryside.

8 . 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．Running on its uneven surface takes much effort.

B．People need to run carefully on its smooth surface.

C．The soft surface makes people fall over easily.

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

2. Which of the following best explains “upside” underlined in Paragraph 2?

A．Character.	B．Reason.
C．Advantage.	D．Challenge.

3. The passage can probably be found in ________.

A．A primary school textbook	B．A sports magazine
C．A tourist guide	D．A scientific report

9 . When it comes to making healthy lifestyle changes, which should come first-changing your diet or becoming more physically active?

Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends (趋向) to be discouraging. That has led to the popularity of advising people to make changes gradually, and set smaller goals.

So the scientists divided 200 inactive participants who were 45 or older into four groups. One group was instructed in making diet and fitness changes at the same time; the second group was taught about diet changes first, and then fitness changes four months later; the third group changed their exercise habits first and made changes in their eating habits four months later; and the final, control group was not instructed in either diet or fitness changes but in how to manage their stress.

The researchers followed the groups for a full year. Compared to the control group, the three intervention (干预) groups made healthy changes in their diet. Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months. However, at the end of the year, the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels, while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year. The researchers suspect that changes to diet are easier to make than changes to physical activity.

The findings show, however, that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives. If folks change diet and exercise orderly, the scientists say, they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

1. How is Paragraph 3 developed?

A．By giving examples.	B．By making comparisons.
C．By analyzing causes.	D．By making classifications.

2. Which group was the most physically active after four months?

A．The first group.	B．The second group.
C．The third group.	D．The control group.

3. What might the scientists approve of?

A．Changing eating habits first may be reasonable.

B．Diet and exercise changes should be made orderly.

C．Diet and exercise changes are equally hard to make.

D．Diet and exercise should be processed at the same time.

4. Which of the following is probably the title of the passage?

A．Changing your habits for better health

B．Ways to lead a healthy and balanced life

C．Making healthy lifestyle changes really counts

D．Timing matters in making diet and exercise changes

10 . Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.

A study followed more than 80,000 people for an average of nine years to find out if certain sports protected them against early death. It found that people who played racket sports regularly were the least likely to die over the study period, reducing their individual risk by 47 percent compared with people who did no exercise. Swimmers also reduced their chance of death by 28 percent, aerobics (有氧运动) fans by 27 percent and cyclists by 15 percent. Yet running appeared to have no impact at all on dying early, and neither did playing football or rugby.

Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash (壁球), which often involve clubs and organized activities outside of the game. It means that people often have larger social net-works and tend to keep up activities into later life, both of which are proven to be good for health.

In contrast, people who play team sports often do not move onto a new sport once their teams break up for family, or injury reasons. They become watchers rather than participants in their chosen activity.

The researchers found that playing racket sports was associated with a 56 percent lower risk from heart death. Similarly, swimmers lowered their heart disease or stroke risk by 41 percent, and people who took part in activities like aerobics, dance or gymnastics lowered their risk by 36 percent. But again running, football and rugby had no significant impact on heart deaths.

However, other experts argue that this study must not be misinterpreted as showing that running and football do not protect against heart disease. In this study both runners and footballers had a lower rate of death from heart disease.

1. Which sport has hardly any impact on protecting people against early death?

A．Cycling.	B．Swimming.
C．Rugby.	D．Tennis.

2. According to the study, which makes a big difference in keeping healthy?

A．Playing basketball with their friends occasionally.

B．Watching football games every day.

C．Taking up gymnastics and joining a club.

D．Doing running in the park every day.

3. What is considered more important to people's health?

A．Social networks.	B．Staying at home.
C．Physical examinations.	D．Setting up families.

4. What is the main idea of the text?

A．Thousands of people participated in a 9-year research.

B．Study finds playing tennis helps people live longer.

C．It is wrong to say running has no impact on heart disease.

D．There are differences between racket sports and team games.
