1 . As is often the case, it is human nature to lead a sedentary（久坐的）lifestyle and most of us are so involved in our busy schedules that we don't even notice our bad habits. Many worry about the right time or "right age" to start working out.     1     Here're some practical tips to help you get fit.

Master your mind. Most people argue that they are too tired or old to start exercising. Doing so is much easier than trying to change the busy lifestyle. Change your mindset and be more confident in improving your health.     2    

Easy does it. Once you have chosen a fitness program, start slowly and increase it in stages. Begin with just a few minutes of gentle exercises and stretches.     3     About 30 minutes should be devoted to your workout. As your body starts to respond and your muscles get used to the exercises, you can gradually increase the length of your workout.

Always warm up. Always remember to warm up your muscles before exercising. Gentle warm-ups will reduce your risk of injury, aches and pains, and increase blood circulation and flexibility.

    4     There's no quick access to getting fit. It's a common mistake to do too much too soon. If you don't know how to balance your needs and your expectations, you might seriously injure your muscles or just create stress.

Cool down. When you finish your routine, you need to cool your muscles and let your heart rate slow gradually.     5    

A．Don't overload your body.

B．Never ignore your potentials.

C．Tell your body to be more active and say, "I can do it."

D．However, nobody cares about what you have done for them.

E．Go next to some mild activity such as walking, jogging or cycling.

F．Cooling down will help your body to return to its pre-exercise level.

G．But it's never too late for them to start exercising and all they need is enough determination.

2 . 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.

Are you looking for a new pastime that will create a balance between physical activity and relaxation? Then yoga may be the perfect choice for you. Yoga can be practiced by people of all ages and levels of fitness.    1     It's a great way to strengthen your muscles and become more flexible.

In the 1930s, Indian Sri Tirumali and K. Pattabhi developed one of the most popular forms of yoga practised worldwide today. They worked together using an ancient Sansknt text called Yoga Korunta to create a set routine of yoga movements and breathing exercises.     2    

Ashtanga is different from other forms of yoga. It is a very powerful form of aerobic (有氧的)exercise which creates deep heat in the body.     3     In other forms of yoga, however, the routine can change each time and the stretching exercises aren't aerobic.

By focusing on your breathing while doing physical exercise, you are able to get a balance between mind and body. In addition, yoga helps to make us healthier so we are less likely to get common illnesses like colds.

6 . Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.

Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.

But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.

For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.

“Even a modest amount of steps is associated with lower death rates, "said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.

The study had a few limitations. For example, the researchers only measured women’s movements once, at the start of the study period. It is possible that the women’s behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.

“Any walking is better than nothing, " Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.

7 . There are lots of skiing lovers around the world. To get the most out of your time on the mountain you should think through each part of your adventure- equipment, clothing, food, and travel.     1    , the more time you can spend on the slopes.

Equipment

Your skiing equipment — composed of your skis, poles, bindings, helmet, and goggles — should be checked over, and possibly tuned up, before you pack your bags for the mountain.     2    . Inspect your boots to make sure they fit properly. Check your goggles and put them on with your helmet to see that they fit comfortably and offer a wide field of view.

Clothing

Your jacket and snow pants should be properly fitting and recently cleaned. Make sure your gloves are in good shape and offer a sense of comfort.     3    . Don’t forget extra items like warm socks, neck warmers and ski masks as well.

Food

Anyone who has ever purchased lunch at the ski lodge knows just how expensive it can be. Packing your own lunch saves you money and gets you back on the slopes faster.     4    , bring plenty of fluids to drink on breaks between runs.

    5    .

Know your way to the mountain before you hit the road and consider writing down directions if you know you’re heading into areas with spotty service. At the mountain, choose a designated meeting place in case the group becomes separated- a spot near the main lift often works well. Check the forecast and current conditions of the mountain. Many ski resorts will have live updates on the number of open trails and lifts.

A．Routes and planning

B．Spots and conditions

C．If you are fully prepared

D．The more prepared you are

E．While bringing a bottle of water with you on the mountain isn’t recommended

F．Besides, long underwear goes a long way in keeping your legs warm and comfortable

G．If you are taking your skis onto the slope for the very first time, they may also need a fresh wax

8 . 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.
C．By imagining.	D．By reasoning.

2. Which of the following is a result of the research?

A．The cyclists kept a thin body shape.

B．The non-exercisers gained weight easily.

C．The cyclists’ muscles remained strong with age.

D．The non-exercisers usually had health problems.

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?

A．Healthy People Need More Exercise

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

9 . 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

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.

10 . For some people, walking or running outdoors is a great way to exercise. What may not be so great is seeing rubbish all over the ground. Well, some people are doing something about it.     1     “Plogging” began in Sweden. The name connects the Swedish word “plocka,” which means to pick up, and the word “jogging,” which means to run slowly.

A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community (社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish.     2    

Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community.     3     It can also build closer social connections in a community. When the street looks bad and it’s dirty, you're going to feel bad about the community. You may even feel less safe because of that. So if we’re all doing our part and picking it up, it’s very easy to help beautify it, and help build those social connection.     4     You get to feel some social duty when you do this.

Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories.     5    

As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.

A．Plogging is equal parts of exercise and community service.

B．And that is how plogging was born!

C．And plogging does good to your health.

D．Usual jogging burns about 235 calories.

E．They are plogging!

F．There are people all around the world doing this.

G．You get to know your neighbors.
