1 . 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。

You already know the fact that regular exercise is important for controlling weight and     1     (avoid)a variety of health conditions. But it can also improve your academic     2    (perform). And. if you’re a distance learning student, you may miss out on some of the opportunities for physical activity afforded to more traditional students who routinely walk around campus. But it’s well worth the effort     3     (put) the schedule exercise into practice.

The study, which     4    (publish) in the Journal of Medicine & Science, describes physical activity as     5     vigorous movement that produces sweat and heavy breathing. Mike McKenzie found that students who studied over three hours per day were 3. 5 times     6    (likely) to be exercisers. Over a decade ago, McKenzie     7     (say) researchers discovered a link     8     exercise and focus in children.

More recently, another study by Johnson reveals that even short ”microbursts“ of physical activity throughout the day can have positive effects. Jennifer tells that sitting for long periods of time,     9    college students tend to do, can have a negative health effect. In addition, the study found that five-minute bouts of walking every hour had a positive impact on mood, tiredness, and hunger at the end of a day. This may be     10    (particular)beneficial to students who also work a full-time job and study in the evening and nighttime hours.

2 . Jumping rope is popular but we tend to ignore (忽视) its benefits.     1     A study found that college men who spent 10 minutes jumping rope daily for six weeks improved their cardiovascular (心血管的) fitness just as much as college men who spent thirty minutes jogging for the same time. Here are some benefits of jumping rope.

    2    

Since most of your major muscles are working when you jump rope, the exercise creates a lot of heat in the body. Your body needs to burn more fuel to produce this energy, so it burns lots of calories. It burns more calories than any other exercises, such as jogging, cycling and swimming.

Improves coordination (协调)

Jumping rope requires good coordination, especially as you advance to more skilled moves.     3     It improves coordination by requiring several body parts to communicate in order to complete one movement. The feet must jump in time with the wrists turning in order to create a continuous jumping motion.

Reduces injury risk

With your improved coordination from jumping rope, you’ll be less likely to get hurt either during exercise or in daily activities.     4     As a result, you are more agile (灵活的) and your body awareness is improved greatly. This guarantees fewer injuries.

Improves heart health

Since jumping rope gets your heart pumping, it’s great for your cardiovascular system and heart health. Jumping rope can increase your VO₂ Max (最大摄氧量), the measure of the maximum amount of oxygen a person can breathe during exercise. The higher someone’s VO₂ max, the more cardiovascular endurance (耐受力) they have.

Jumping rope gives us a full-body workout with just one piece of equipment and one move.     5     Jump to some music, or take your rope to a nearby park to enjoy the fun.

A．Burns calories

B．Improves muscles

C．It benefits us not only physically but also mentally.

D．You can quickly swing the rope twice within each jump.

E．It may even be more effective than other forms of exercise.

F．Jumping rope forces you to move your upper and lower body together.

G．So jumping rope helps you stay calm, clear and focused in everything you do.

3 . Spending time outdoors has long been linked (联系) to better health. Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental (身心上的) health.

Gardening involves physical activity that works all the main muscle (肌肉) groups, which is helpful for overall health. “Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength,” said Clayton, CEO of an online lawn care company. “Performing these activities regularly can help burn calories, and keep a healthy weight.”

Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统). The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity. Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease. Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth.

Gardening provides a chance for social connection, too. It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging.

Gardening also offers cognitive (认知的) benefits. It excites the senses, improves focus and encourages problem-solving and creativity. It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature.

1. What is Clayton’s attitude towards gardening?

A．Supportive.

B．Doubtful.

C．Unclear

D．Uncaring.

2. What does paragraph 3 mainly tell us about gardening?

A．It improves focus.	B．It is a waste of time.

3. How does gardening affect social connection according to the text?

A．It contributes to creativity.	B．It encourages problem-solving.
C．It builds relationships between people.	D．It improves people’s awareness of safety.

4. What is the best title for the text?

A．How to Start a Garden	B．Choose a Garden or Not
C．What Plants Grow Best in a Garden	D．Start Gardening and Get the Health Benefits

6 . A new study involving nearly 50,000 people from four continents offers new insights into identifying the quantity of daily walking steps that will best improve adults’ health and longevity(长寿), and whether the ideal number of steps differs across people of different ages. The study represents an effort to develop an evidence-based public health message about the benefits of physical activity. The often-repeated 10,000-step-a-day saying grew out of a decades-old marketing activity for a Japanese pedometer(计步器), with no science to back it up.

Led by physical activity professor Amanda Paluch, an international group of scientists conducted an experiment among adults aged 18 and older. They grouped the nearly 50,000 participants into four comparative groups according to average steps per day. The lowest step group averaged 3,500 steps; the second, 5,800; the third, 7,800; and the fourth, 10,900 steps per day. Among the three higher active groups, there was a 40—53% lower risk of death, compared to the lowest step group.

More specifically, for adults 60 and older, the risk of early death leveled off at about 6,000—8,000 steps per day, meaning that more steps than that provided no additional benefit for longevity, while for adults younger than 60, about 8, 000—10,000 steps per day.

“So, what we saw was this continuing reduction in risk as the number of steps increases, until it levels off. Interestingly, the study found no definitive association with walking speed.” Paluch says.

The new study supports and expands findings from another study led by Paluch before, which found that walking at least 7,000 steps a day reduced middle-aged people’s risk of early death. “There’s a lot of evidence suggesting that moving even a little more is beneficial, particularly for those who are doing very little activity.” Paluch says. “More steps per day are better for your health.”

1. Why did the scientists carry out the new study?

A．To know about people’s health condition.

B．To explain the pedometer’s working principles.

C．To determine the best physical activity for people.

D．To provide a scientific guideline on daily walking.

2. What does the underlined words “leveled off” in paragraph 3 mean?

A．Turned higher.

B．Became stable.

C．Fell sharply.

D．Changed rapidly.

3. What does the experiment find?

A．The old should walk as much as possible.

B．Young people usually walk more than the old.

C．The most beneficial steps differ by age groups.

D．Walking pace is the key to avoiding early death.

4. What does Paluch advise people doing little activity to do?

A．To walk more steps.	B．To control walking speed.
C．To limit walking distance.	D．To track the number of steps.

7 . Maybe you plan to ring in 2023 with a new resolve to lose weight, exercise more, not sweat the small stuff. And maybe these resolutions sound familiar — maybe just like the ones you made a year ago! So how can you ensure that your determination to get healthier in 2023 sticks?    1    

Dream big. Want to compete in a marathon or triathlon? Lose 50 pounds or just enough to fit into clothes you once loved? With perseverance (毅力), encouragement, and support, you can do it.     2    Many will cheer you on. Some will be happy to help in practical ways, such as by training with you or taking on tasks you normally handle in order to free up your time.

    3    Any time you fail to make a change, consider it a step toward your goal. Why? Because each sincere attempt represents a lesson learned. When you hit a snag (碰钉子), take a moment to think about what did and didn’t work. Maybe you took on too big a challenge?     4    

Give thanks for what you do. Set your sights on finishing that marathon,not on running it. If you compete to complete, you’ll be a winner even if you wind up walking as much as you run. With exercise — and so many other goals we set — you’ll benefit even when doing less than you’d like to do.     5    If your goal for Tuesday is a 30-minute workout at the gym, but you only squeeze (挤出) in 10 minutes, feel grateful for that. It’s enough. Maybe tomorrow will be better.

A．Learn from the failures.

B．Avoid repeating past failures.

C．Any activity is always better than none.

D．An ambitious aim often inspires others to help you.

E．Try the following tips to help you create long-lasting change.

F．Having a solid system can help you stay motivated and accountable.

G．If so, change into a less ambitious challenge, or break the big one into tinier steps.

8 . One of the presents in my house this Christmas was a late 18th-century volume of the Encyclopaedia Britannica (大英百科全书). It is a window into the discoveries and thinking of the time. The encyclopaedia is an entertaining reminder of how _______ some of our current truths are bound to be. Certainties in areas we haven’t yet understood will look just as ridiculous as some of these in centuries to come. And one of those we are still remarkably _______ is the effect of food and exercise on our bodies. We’re surrounded by confident _______ on how to eat, how to avoid or reverse obesity (肥胖), and yet the advice seems pointless while the world gets fatter. Much of what we think we know is a pile of assumptions rather than _______ .

Our confusion is the theme of Spoon-Fed, a book by one of Britain’s leading nutrition researchers, Tim Spector of King’s College London. Its subtitle is: “Why almost everything we’ve been told about food is wrong.” It is a call for us to _______ more.

One by one Spector offers answers to recent food _______. Coffee can save our lives, he says. Three to four cups a day reduces the risk of heart disease and may cut the risk of death by 8 per cent. Butter does not damage our hearts, Spector argues, and salt is vital. Eggs have gone “from heroes to villains and back again”. Don’t say no to all red meat on _______ grounds; occasional small quantities of high-quality unprocessed meat provide important vitamins and iron and are “probably good for you“. Exercise is so good for longevity and happiness that it should be considered our No 1 drug, but the one thing for which it’s _______ useless is losing weight. Vitamin pills are a multibillion-pound industry with almost no proven _______ but which can cause real harm. Even vitamin D, which Spector used to study and believe in, he now _______.

Spector also offers more than a set of currently _______ tips. The science of nutrition has not been solved by him, as he would be the first to admit. His most _______ point is that there is no one size that fits all. Our bodies are complex, and our reactions are _______: yet nobody wants to pay for the research that might explain why.

Some combination of food choices, genes, environment and the chemical reactions generated by our microbiome — the unique microbe (微生物的) combinations in our body ― yes different _______ for each of us, leaving some lean and two thirds of us too fat. This is the territory Spector wants to explore further and which might just allow us to _______ the global trend to obesity, with all the risks we’ve witnessed this year.

9 . Are you sitting more than ever?     1     You’re probably sitting while reading this. Sometimes you sit when you are driving or attending a meeting. Other times you sit when you engage yourself in watching a movie or playing computer games. That’s undoubtedly a lot of sitting. The fact is, the amount of time spent sitting has increased over time.     2    

We know sitting too much is bad, and most of us naturally feel a little guilty after a long-time TV watching.     3     A study on nearly 8,000 adults suggests that there’s a direct relationship between the time spent sitting and our risk of early death of any cause. As the total sitting time increases, so does the risk of early death.

“Sit less, move more” is what the Heart Association encourages us to do.     4     It is like telling someone to just ”exercise“ without telling them how. Exercise guidelines are always more practical. For example, the Center for Disease Control recommends adults do exercise for two hours and 30 minutes every week, plus muscle strengthening activities two or more days a week. We need similar guidelines for sitting.

    5     “It would probably be like, for every 30 continuous minutes of sitting, stand up and move or walk for five minutes at a quick pace,” Diaz, the lead researcher said, adding that the study has put us a step closer to the satisfying guidelines. But more researches are needed to confirm their approach.

A．Now it’s time to get up and move around.

B．Take a moment to think about your sitting activities.

C．Health experts also suggest exercising on a daily basis.

D．But this guideline is just too simple and abstract to make a difference.

E．As of today, average adult will spend 56-86% of their daily time sitting.

F．But what exactly goes wrong when we park ourselves for nearly eight hours per day?

G．To make up for the weakness, a research team is working on a more specific guideline.

10 .                                                                                      You May Need a Few Minutes of Brisk Activity

Walking from room to room, running up and down stairs to deliver folded laundry, or taking a jog around the block... Which ones would best help or hurt your brain? A recent study attempted to a answer that question by strapping( 绑上) activity monitors to the thighs of nearly 4,500 people in the United Kingdom and ________ their 24-hour movements for seven days. Researchers then examined how participants’ behavior affected their short-term memory, problem-solving and processing skills.

Here’s the good news. People who spent “even small amounts of time in more vigorous activities—as little as six to nine minutes—compared to sitting, sleeping or gentle activities had ________ cognition scores,” said study author John Mitchell.

Moderate physical activity is ________ defined as brisk walking or bicycling or running up and down stairs. Vigorous movement ________ dancing, jogging, running, swimming to biking up a hill—basically any activity that is able to ________ your heart rate and breathing.

The study found that doing just under 10 minutes of moderate to vigorous physical activity (MVPA) each day led to ________ in study participants’ working memory. In addition, 10 minutes of MVPA had its biggest impact on executive processes such as ________and organization.

The cognitive improvement was ________, but the research found that the benefits grew the more time a person spent ________in the activity of an energetic workout, Mitchell said.

“Now that we don’t monitor participants’ cognition over the course of many years, the results of this study may simply be telling us that those individuals who move more tend to have higher cognition on average,” he said. “While on the other hand, the results do also imply that even making ________ changes to our daily lives can have ________ consequences for our cognition.”

There was bad news as well. Spending more time sleeping, sitting or engaged only in mild movement was linked to a negative impact on the brain. The study found cognition declined 1% to 2% after replacing an ________ portion of MVPA with eight minutes of sedentary (久坐的) behavior, six minutes of light intensity or seven minutes of sleep.

Additional studies need to be done to ________ these findings and to better understand the role that each type of activity plays ________ our cognitive abilities. However, Mitchell said, the study “highlights how even very modest differences in people’s daily movements— less than 10 minutes— can be linked to the ________of quite real changes to our cognitive health.”
