1 . Are you trying to find the best time for exercise?     1     Follow these tips to figure out what fitness routine works best for you.

Dawn, dusk or dead of night — when’s the best time to work out? Well, that depends on when’s the best time for you, because the benefits of physical activity depend upon how consistent you are.     2     But if you’re not a morning person, it may not work for you to try to get up at dawn to work out. The key is to do what’s most likely to work for you consistently.

    3     If you find that working out too late in the evening keeps you from falling asleep easily, shift your exercise session earlier in the day or try less intense, more mindful forms of movement.

To stay motivated, choose activities you enjoy. If you’re a social person, do something that engages you socially. Take a group exercise class, join a recreational team or walk with a group of friends. If you prefer having time alone, walking, swimming or biking solo might be a better fit for you.     4    

There are so many choices.     5     Having a variety of fitness activities to choose from may keep you from getting bored or burnt out.

A．The truth is, it’s personal!

B．Don’t limit yourself to just one.

C．There are other important considerations.

D．Use your body clock as a guide to when to go for a walk.

E．You might have heard that the best time to exercise is early in the morning.

F．If you’d like to spend more time with your family, find an activity you can all do together.

G．If your schedule isn’t predictable (可预测的), you may need to be flexible and have a plan for various times of day.

2 . 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 . The decision on Tuesday by Japan and the International Olympic Committee (IOC) to postpone the Tokyo 2020 Olympic Games until next summer because of the novel coronavirus pandemic must have been a hard one to make.

Although the Games have been canceled—three times in all, in 1916, 1940 and 1944—due to the two world wars in the modern Olympics’ history of more than 120 years, never before have any Games been postponed to a different year.

Nonetheless, the decision is the right one. If it is not brought under control, the harm done to human society by the pandemic could be more serious and far-reaching than even the two world wars. Given the number of countries affected and social and economic shock waves that have been caused by the rapid spread of the virus, postponing the Games is the only right and sensible choice to make.

After all, nothing is more important than people’s lives. Postponing the Games not only safeguards the health of athletes, audiences and everyone involved in the Games, but also reduces potential transmission of the virus from one place to another. Even looking at it from only a sporting level, the pandemic has already caused huge disruptions to athletes’ training and the qualification process.

It is undoubtedly a big blow for Japan, which has prepared meticulously for the largest sports event in the world, including renovating and upgrading its infrastructure and sports venues, such as rebuilding Tokyo’s Olympic Stadium at cost of $1.45 billion. Japan will suffer huge loss at least in the short term.

The international community owes a big “thank you” to Japan for all it has done for the Games despite the postponement. That’s why the Games will still be called the Olympic and Paralympic Games Tokyo 2020 despite taking place in 2021. The Olympic flame will also remain stored and displayed in Japan.

More importantly, all members in the Olympic family, guided by the Olympic spirit of respect and understanding are morally bound to stand behind Japan to go through this most difficult moment in the Games’ history.

B．the Games will still be called Tokyo 2020 Games for its sacrifice

4. What can we learn from the last paragraph?

5 . 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.

1. Why are race walkers conditioned athletes?

A．They must run long distances.

B．They are qualified for the marathon.

3. What is Dr. Norberg’s suggestion for someone trying race walking?

A．Getting experts’ opinions.

B．Having a medical checkup.

C．Hiring an experienced coach.

D．Doing regular exercises.

4. Which word best describes the author’s attitude to race walking?

A．Skeptical.	B．Objective.
C．Tolerant.	D．Conservative.

6 . 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.

A．Swimmers should concentrate on details.

B．Members get disciplined and focused in the team.

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.
