Research has showed physical activities are very important for students. So many schools are now encouraging students to take part in any form of healthy exercise.
Physical education is an important part of healthy living for people of all age groups, especially for the students. This is because school life is full of stress.
Besides that, in today’s world, many school children eat unhealthy foods. These may include soft drinks, pizzas and burgers. Eating these foods can make school children gain weight.
Physical education at school helps prevent school children from putting on weight. Physical exercise and activities will help them burn off more calories (卡路里). If these calories are not burned off, they will be stored as fat.
At the same time, such activities play an important role in the growth and development of the bones (骨骼). Exercise such as jumping is especially important for school children.
A physically active student will also have a healthy heart. Research shows that kids who perform aerobic (有氧的) exercise, two to three times a week for at least twenty minutes, have a healthier heart compared with those who don’t take part in physical exercise. Some kinds of the healthy aerobic exercise are playing basketball, playing soccer and so on.

【推荐3】Shooting down an ice-covered track, a bobsled can go faster than 80 miles an hour.
At the start of a race, the crews push their sled, building up speed before they jump in for the ride. For months before the race, the crew members have built up explosive power in their legs. That means doing a lot of jumps, and sprints. It also means pushing heavy sleds! The push is the crew's only chance to add speed.
The design of the sled's runners (滑板) reduces their friction with the ice.
But remember the sled must not be too fast — the crew still needs to be able to reach the bottom safely.
| A．Why do people go for the sport? |
| B．Crews polish their runners for a fast ride. |
| C．The riders sit inside a hard shell, called cowling. |

【推荐1】Cool to be kind: being nice is good for us so why don’t we all do it
What is it, exactly, that makes us kind? The Kindness Test suggests that people who receive, give or even just notice more acts of kindness tend to experience higher levels of well-being and life satisfaction.
People who have been told they should be kind are naturally more likely to notice opportunities to be kind: “They have expectations. Then, they take action,” she says. This may be one of the reasons why women who filled in the study’s online questionnaire were more likely to report being kind, receiving kindness and seeing kindness. Women may feel that they ought to report performing acts of kindness.
Overall, the study suggests the greatest predictor of kindness is not your gender, but your personality. People who scored high on extraversion(外向性), openness to new experiences and agreeableness self-reported giving and receiving more kindness, as did people who talking to strangers.
| A．It is because caring for people is an activity traditionally considered to be typical of women. |
| B．It is sometimes used to shut women down from talking because they’ve got to ‘be kind’. |
| C．The reason for this may simply be that these people have more confidence to be kind. |
| D．Your religious beliefs and your values system also help to determine how kind you are. |
| E．Also, two-thirds of people in the study think the pandemic has made people kinder. |
| F．Our desire to be kind is actually quite selfish, on one level, she explains. |
【推荐2】Aging happens to all of us, and is widely thought of as a natural part of life. It would seem silly to call such a thing a “disease.”
On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency(不足).
Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives(动机) to develop treatments.
“It unties the hands of the pharmaceutical (制药的) industry so that they can begin treating the disease and not just the side effects,” he said.
“Right now, people think of aging as natural and something you can’t control,” he said. “In academic circles, people take aging research as just an interest area where they can try to develop interventions（介入，参与）. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”
But if aging were recognized as a disease, he said, “It would attract funding and change the way we do health care. What matters is understand that aging is curable.”
“It was always known that the body accumulates damage,” he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”
Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.
“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were removed, life expectancy would still not go much beyond 92 years.”

【推荐3】We’ve known for years that plants can see, hear, smell and communicate with chemicals. Now, reported New Scientist, they have been recorded making sounds when stressed.
In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic（超声的）noises. The plants “cry out” due to lack of water, or when their stems are cut. It’s just too high-pitched（音调高的）for humans to hear.
Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz（千赫兹）. Human hearing usually ranges from 20 hertz to 20 kilohertz. “These findings can alter the way we think about the plant kingdom,” they wrote.
On average, “thirsty” tomato plants made 35 sounds an hour, while tobacco plants made 11. When plant stems were cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15. Unstressed plants produced fewer than one sound per hour, on average.
Perhaps most interestingly, different types of stress led to different sounds. The researchers trained a machine-learning model to separate the plants’ sounds from those of the wind, rain and other noises of the greenhouse. In most cases, it correctly identified whether the stress was caused by dryness or a cut, based on a sound’s intensity and frequency. Water-hungry tobacco appears to make louder sounds than cut tobacco, for example. Although Khait and his colleagues only looked at tomato and tobacco plants, they think other plants also make sounds when stressed.
If farmers could hear these sounds, said the team, they could give water to the plants that need it most. As climate change causes more droughts, they said this would be important information for farmers. “The sounds that drought-stressed plants make could be used in precision agriculture（精准农业）,” said Anne Visscher at the Royal Botanic Gardens, Kew, in the UK.
Khait’s report also suggests that insects and mammals can hear the sounds up to 5 meters away and respond. For example, a moth may decide not to lay eggs on a water-stressed plant. Edward Farmer, at the University of Lausanne, Switzerland, is doubtful. He said that the idea of moths listening to plants is “a little too speculative”.
If plants are screaming for fear of their survival, should we be thankful we can’t hear them?

【推荐1】The message is drummed into us from childhood: forgive people who’ve wronged you, because it’s the right thing to do. Forgiveness is a virtue, we’re told—the only way for us to truly move on and heal, freed from the baggage of bearing ill will.
However, I’m not buying it. Forgiving someone can indeed be a beautiful thing, but it’s not always what’s best for us. In fact, if someone has hurt you deeply and the relationship isn’t healthy, trying to “fix” things can do more harm than good.
Most of us would probably agree that forgiving a wrongdoer means letting go of negative feelings—like anger and resentment—towards them, as if nothing happened. Actually this isn’t helpful. It pressures us to minimize our feelings and revise our boundaries—to say “it’s OK” when for us, it isn’t. While it’s not a good idea to focus on negative thoughts, recognizing and processing all of that pain is an important part of the healing journey. And when someone doesn’t make us feel seen or safe, forgiving them can actually reduce our self-esteem.
A 2010 research paper published in the Journal of Personality and Social Psychology found that folks who forgave partners that didn’t make them feel valued had less respect for themselves. Letting minor offences that happen now and again slide can be great for any relationship, but repeatedly forgiving bad behavior can encourage that person to keep hurting you.
At least, that’s what 2011 research by psychology professor James McNulty argues. He found that when a partner was more likely to forgive those acts, the aggressor was more likely to keep committing them. McNulty suggests that this is because facing the consequences of their actions is what motivates people to change their ways, and being offered a clean slate can be a kind of pass to avoid making changes. So forgiving frequent and major offences, like verbal or physical abuse, can do more harm than good.
For me, this speaks to the core tension in the idea. Instead of looking to forgiveness like a magic medicine, we can focus on recognizing what happened and coming to terms with it, however that looks for us and without any sense of obligation towards our offender.

【推荐2】Is beauty something always positive? Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive(主管的) circle, beauty can become a disadvantage.
While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman. Handsome male executives were considered having more honesty than plainer men; effort and ability were thought to lead to their success. Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck.
All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Why are attractive women not thought to be able? An attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the manly qualities required.
This is true even in politics. “When the only clue is how he or she looks, people treat men and women differently,” says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 college students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.

【推荐3】The other day a friend,a sociable man,told me he had found himself alone in New York for an hour or two between appointments.He went to the Whitney and spent the"empty"time looking at things.He then felt unexpectedly happy.Suddenly alone,he discovered there was a new self to meet.
＂One alone is never lonely."There is great difference between being alone and lonely.Loneliness is most strongly felt with other people,for with others,even with a lover sometimes,we suffer from our differences of tastes,personalities and moods.The fear of hurting or being hurt in a social situation brings us loneliness.Alone,we can afford to be wholly whatever we are,and to feel whatever we feel absolutely. That is a great luxury(奢侈）！
I have been alone for the last twenty years and it becomes increasingly rewarding.When I can wake up and watch the sun rise over the ocean,as I do most days,and I know that I have an entire day ahead, uninterrupted,in which to write a few pages,take a walk with my dog,lie down in the afternoon for a long think,read and listen to music,I am flooded with happiness.
I'm lonely only when I am overtired,when I have worked too long without a break,when from the time being I feel empty and need filling up.And I am lonely sometimes when I come back home after a lecture trip,when I have seen a lot of people and talked a lot,and am full to brimful(满满的）experience that needs to be sorted out.Then I need to be alone to find where my self is hiding.
It takes a while, but the moment comes when the world falls away,and the self comes out again from the unconscious,bringing back all I have recently experienced to be explored and slowly understood.
