3 . 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.

4 . Clocking 16 hours, 46 minutes, nine seconds, the athlete Chris Niki didn’t finish with the shortest time when he recently completed his first Iron Man Race-but he did quite well.

After swimming 2. 4 miles, the 21-year-old Floridian cycled 112 miles. Even after suffering a fall from his bike during the second leg of the race, he called on his inner strength to get back up, keep going and get the job done. And then he ran a 26. 2-mile marathon (马拉松) to become the first competitor with Down’s Syndrome (唐氏综合征) in the world to successfully cross the finish line in the history of the Iron Man Race. For his efforts, Niki also earned himself a place in the Guinness Book of World Records.

“To Niki, this race was more than just a finish line and a celebration for the success,”his dad said. “The race has served as a chance to become one step closer to his goal of living a normal life. It’s about being an example to other kids and families that face similar difficulties. Those with Down’s Syndrome will be prompted to live a life like normal persons.”

Niki trained between four and six hours a day to prepare for the event, and that training paid off.

“Goal set and achieved, ” Niki posted on Instagram, where he has 33, 000 new followers. “Time to set a new and bigger goal for 2021. ”

One of Niki’s biggest fans, all-time tennis great Billie Jean King, tweeted the perfect response: “No limits. No boundaries (边界). Keep dreaming big and going for it！”

As for that medal he won for completing the race, he gifted it to his loving mom. With hopes of competing in the 2022 Special Olympics scheduled in Orlando, it looks as if Chris Niki has plenty of big dreams yet to come true.

5 . If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.

Scientists in Denmark have been studying over 1,000 joggers and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries.

Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”

The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and long-distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study， “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn't actually do too much.”

1. The underlined word “strenuous” in Paragraph 1 is closest in meaning to “________”．

A．hard	B．regular
C．practical	D．little

2. The author presents some figures in Paragraph 2 to ________.

A．suggest giving up jogging	B．show risks of doing sports

3. According to the scientists, why is too much exercise harmful?

A．It may injure the heart and arteries.	B．It can make the body tired out.
C．It will bring much pressure.	D．It consumes too much energy.

4. What can be inferred from the text?

A．Jogging is the best exercise.

B．More exercise means a healthier life.

C．Marathons runners are least likely to die.

D．Proper exercise contributes to good health.

6 . 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

According to    1    new study by the WHO, about 25% of adults worldwide do not get enough exercise. Because of this, about 1.4 billion people are     2    greater risk of    3    (dead) diseases such as heart disease and cancer.

When it comes to    4    (exercise) more, experts say that people needn't go to the gym every day. There are other ways to exercise. For example, we can take the stairs instead of taking an elevator. And standing on one leg for 30 seconds each day    5    (be) also good for our health.

The study also found that on average women are less active than men for the reason that    6    have to spend more time at home in taking care of    7    (child) and doing housework.

Countries with higher incomes showed higher rates of inactivity (静止不活动). For example, people in the US exercise less    8    people in Nepal. This is partly because in    9    (develop) areas, desk jobs have taken the place of physical labour and driving cars    10    (replace) walking.

7 . All of my five children played team sports in middle school and high school, and four of them are in college.     1    .

Teenagers may get into bad habits.     2     According to a study in Archives of Pediatric & Adolescent Medicine, a survey of more than 14,000 teenagers found that those who had taken part in team sports were less likely to smoke or have unhealthy eating habits.

As children get older, they naturally develop their own lives and there will be fewer ways for parents to be involved（参与）. Some teenagers shut their parents out of their room.    3    .

Sports build strong and healthy bodies. Children who compete know that they are only at their best if they eat and rest well.    4     In sports, strength and speed are wanted. Team sports help kids avoid obesity（肥胖） problems even better than activities like running or biking.

    5     The joy of a sports season stays with us long after the season is over. Our children may forget who was in their English class or which math teacher they had in the 10th grade one day. But they will never forget their sports teams.

A．Team sports can bring lifelong memories.

B．Team sports make a child’s social world wider.

C．As a matter of fact, doing sports makes us a better family.

D．However, they still want their parents to attend their games.

E．Cigarettes and drugs harm their performance and every athlete knows that.

F．But teenagers who often take part in team sports have less time for bad behavior.

G．From their experiences, I’ve learned it’s important for children to play team sports.
