1 . 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.”

3 . 阅读下列短文，在空白处填入一个适当的单词或括号内单词的正确形式。

Exercise is one of the best     1    (thing) you can do for health. But how about your sleep? The answer is that being active during     2    day can improve sleep at night.

People who exercise     3    (regular) get better sleep than those who don’t. Exercise increases chemicals which can increase the body temperature. That may lead to the decrease of body temperature at night, allowing people     4    (experience) deeper sleep.

For most people, the time     5    they take exercise doesn’t matter. However, late afternoon might be the best choice for too much exercise. Morning might be a choice     6     (prefer) by people for ongoing training. And make it a regular part of your routine to keep up once the best type of exercise for yourself     7    (decide).

As for the amount of exercise, it is wise to work out about 150 minutes every week,     8    about 30 minutes each day, five days a week. Little things you do all day long can add up, from taking the stairs     9    walking instead of driving. Try to spend fewer minutes     10    (sit) all the day.

5 . 阅读下面材料，根据中文及相关提示翻译下列句子。

Pilates(普拉提), yoga and running, whether in the gym or at home, get all the attention when it comes to popular ways to keep fit.    1    (与它们相比，散步不是这么有吸引力，但它却有很多益处。)

Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Besides, it is good for your heart, your head and your wallet.     2    (很明显，散步是让人惊叹的运动，不是吗？)”

Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduced the risk of heart disease more effectively than running.     3     (正是因为这个原因，一些有心脏病的人喜欢散步胜于跑步。) Scientists observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is better news: 30 minutes of quick walking over five days could help people sleep easily, according to research by Oregon State University.    4    (散步帮助青少年更好地睡眠，使得他们积极参加学校活动并专注于学校生活。)

    5    (你越早开始，你将会越早注意到散步对你的大脑和身体有巨大影响。) So, go out for your 30-minute walk in a nearby park or green space.

Yoga(瑜伽) is     1     (high) recognized for improving balance and bringing calm. But when it comes to weight loss, many people think that other kinds of exercise, like running, will be more     2     (help). But studies show that yoga,     3       is an exercise that uses your large muscle groups     4     raises your heart rate, is beneficial for you to lose weight. Just how many calories(卡路里) you burn differs, depending     5     how long your exercise is, as well as other     6     (factor), such as your weight and age. Practicing yoga can help you burn more calories long after exercise.

Better yet, recently several studies     7     (prove) that yoga has an effect on the body’s stress response and reduces     8     production of chemicals linked to weight gain. And someone experiencing a more positive mood by     9     (practise) yoga is less likely to overeat when experiencing negative emotions.

Remember     10     (choose) the best kind of yoga that fits for you. There are now many styles of yoga that meet you no matter what your size, age, or physical challenge is. Everybody can benefit from a yoga practice.

8 . About one-third of adults globally have high blood pressure, which increases the risk of having a heart attack or stroke (中风). Physical activity is known to lower blood pressure. However, many people have trouble keeping to exercise plans.

Yoga tends to be more sustainable (可持续的) than other forms of exercise because it is gentle, can be done with others and helps to relax the mind. Several experiments have found that yoga lowers blood pressure. However, these experiments have typically involved several sessions a week, which may not be achievable for many people.

To find out if yoga helps to reduce blood pressure in the real world, some researchers conducted a new study and analysed the electronic health records of 1,355 people aged 18 to 79 who practised yoga at least once a week. They compared each of these people with at least three other individuals. They had similar characteristics in terms of things like age, gender, and body mass index (BMI), but had no mention of practising yoga in their records. On average, the people who practised yoga had systolic blood pressure (收缩压) that was 2.8 mmHg lower and diastolic blood pressure (舒张压) that was 1.5 mmHg lower than those who didn’t.

This blood pressure reduction probably wouldn’t make a huge difference to most people in the study, since they tended to be young and healthy. They already had normal blood pressure. But at a population level, if average blood pressure declined by this much, it would prevent a significant number of heart attacks and strokes. For example, a 2018 study found that a population-wide average systolic blood pressure reduction of 2 mmHg among middle-aged adults in the US would prevent more than 12,000 heart attacks and 7,000 strokes each year.

Based on the new study, we can’t say for sure that yoga lowers blood pressure, because there may be other explanations for the findings. People who do yoga may have lower blood pressure because they tend to have better diets, not because of the yoga itself. And yoga shouldn’t be seen as the replacement for blood pressure lowering medicines. Nevertheless, yoga is likely to assist in lowering blood pressure if it encourages sedentary (久坐的) people to exercise. “The greatest benefit is getting the exercise-shy to do something rather than increasing exercise in someone who does it regularly,” an expert says.

9 . 阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

When it comes to exercise, less is not more—but it’s certainly better than none. Physical inactivity makes up nearly 23 percent of all     1     (death)from major chronic(慢性的)diseases, yet almost one of every three Americans spend a lot of time sitting down. They usually say they have no free time     2     physical activity at all.

Light activity can improve physical and mental well-being. While light activity is good, moderate(适度的)activity is even     3     (good). And you don’t have to head to a gym. As recent studies have suggested, “lifestyle” activities, such as walking, house cleaning and gardening, are as     4     (effect)as a structured exercise program in improving heart function(功能), lowering blood pressure     5     keeping or losing weight.

In one study, overweight, sedentary(久坐的)middle-aged men and women     6     learned behavioral skills to make them more physically active, such as walking around airports or train stations while waiting for a departure,     7     (reduce)their body fat percentage and improved their blood pressure and heart function as much as individuals(个人)working out at a     8     (fit)center.

There are different types of activity in a center,     9     people do aerobic and muscle exercise to build up their health. But actually multiple short periods of exercise during the day     10     (be)nearly as beneficial as one long session.
