1 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

3 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s study and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖症). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as video games and computer activities, means many teens don’t get their required exercise. PE classes act as a public health measure to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ risk of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be hindered by lifestyle changes,according to the American College of Sports Medicine.

According to the President’s Council on Fitness,Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

1. According to paragraph 2, what does physical education in high school mean?

A．Making teens attach importance to exercise later.

5 . I’m sure we all know that exercise is great for our health．But sometimes finding that motivation(动力) to work out can be a little difficult．So, in this post, I’m going to share my top four reasons for working out．

    1    

Whenever I move to a new city to study or work, I look for exercise classes to do．You meet like­minded people, and you can support each other during a difficult workout．    2    

Exercise makes you feel confident(自信的)．

We all know the physical advantages of exercise on our bodies but we don’t always talk about the mental(心理的)ones．     3    This new confidence might even help in your social or work life．

Exercise helps to reduce stress(压力)．

Going for a run can help you forget the problems and worries of daily life．    4    It makes me feel less worried and it also helps me to sleep those important eight hours the night before a big exam．

Finally, exercise makes us feel strong and healthy!

Every day, the 20 minutes in the gym get easier, the weights feel lighter and you feel a great sense of achievement．    5    

So, next time you’re feeling down or stressed, put your trainers on and get some exercise．It might not be easy but I promise you’ll feel so much better once you’ve finished!

A．Exercising is sociable．

B．Exercise can change your mind．

C．During exams, I always spend an hour a day in the gym．

D．When the class finishes, you all share a collective feeling of happiness!

E．When you work out, your body produces something that makes you happy．

F．It’s a great feeling doing something you couldn’t do before through hard work．

G．Exercise might give you a feeling of confidence from being comfortable with your body．

6 . Why Is Exercise Cool?

•Exercise Strengthens Muscles

Did you ever do a push-up or swing across the monkey bars at the playground?    1    By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.

•    2    

Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion”, which means you can move your arms and legs freely without feeling tightness or pain.

•Exercise Keeps the Balance

    3    Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic things.    4    If you’re not very active, your body won’t need as many calories. Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.

•Exercise Makes You Feel good

It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.

But you may not know that exercising can actually put you in a better mood.    5    It’s just another reason why exercise is cool!

A．Exercise Makes You Flexible

B．Exercise Makes Your Heart Happy

C．Those are exercises that can build strength.

D．So you want to do some aerobic (有氧的) exercise right now?

E．But if you’re active, your body needs an extra measure of calories or energy.

F．Food gives your body fuel in the form of calories, which are a kind of energy.

G．When you exercise, your brain releases a chemical which may make you feel happier.

7 . 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.

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.

1. How did the researchers carry out the study?

A．By comparing.	B．By discussing.

3. Which is an unexpected result for the researchers?

A．The cyclists had normal aging process.

B．The cyclists’ immune systems didn’t age.

C．The cyclists lost nearly all their fat.

D．Everyone needed an exercise in their lives.

4. Which of the following can be the best title for the text?
