If you're a runner who secretly hates running, here's some good news: settling into a leisurely jog rather than an all-out run may actually be better for your health in the long term.
A team from Denmark followed over 5,000 people taking part in the Copenhagen City Heart Study, and tracked whether they were non-joggers or joggers who kept a slow, moderate, or fast pace. The participants' health was tracked over the next 12 years, and so was their mortality (死亡率): 28 of the joggers and 128 of the non-joggers died.
The connection was this: Joggers of mild and moderate intensity had a lower risk of death than the fast joggers. In fact, the lowest mortality risk was that of the mild intensity joggers. The fast-paced joggers had about the same mortality rate as sedentary (久坐的) people. This suggests that there may be an upper limit to hard exercise, after which the benefits fall off.
"The U-shaped association between jogging and mortality suggests there may be an upper limit for exercise amount that is best for health benefits," said study author Peter Schnohr. "Anything more is not just unnecessary: it may be harmful." From the current study, jogging just three times per week, for less than 2.5 hours/week was associated with the lowest overall mortality risk.
There've been a lot of mixed messages about the "right" amount of exercise and what intensity is best. The World Health Organization has suggested that the current 150 minutes/week recommendations are strenuous for most people to tackle, and that expectations should be lowered, since, after all, anything is better than nothing. Everyone probably has a level of activity that feels best to him or her. But at least the growing consensus seems to be that more-if you're pushing yourself very hard-is not necessarily better. And it may even be worse.

The study, conducted-at the-University of Plymouth, compared how adults and children respond to an identical (相同的) task when in the presence of both their peers (同龄人) and robots.
It showed that while adults regularly have their opinions influenced by peers, something also demonstrated in previous studies, they are largely able to resist being persuaded by robots. However, children aged between seven and nine were more likely to give the same responses as the robots, even if they were obviously incorrect.
The study asks people to look at a screen showing four lines and say which two match in length. When alone, people almost never make a mistake but when doing the experiment with others, they tend to follow what others are saying.
When children were alone in the room in this research, they scored 87%on the test, but when the robots join in their score drops to 75%. And of the wrong answers, 74% matched those of the robot.
Professor Belpaeme said, ”People often follow the opinions of others and we’ve known for a long time that it is hard to resist taking over views and opinions of people around-us. But as robots will soon be found in the home and the workplace, we were wondering if people would follow robots. What our results show is that adults do not follow what the robots are saying. But when we did the experiment with children, they did. It shows children can perhaps have more of an affinity (亲和力)with robots than adults, which does pose the question: What if robots were to suggest, for example, what products to buy or what to think?“?
1. What did the adults do when staying with robots?| A．They generally refused the robots’ effects. |
| B．They totally accepted the robots’ suggestions. |
| C．They tried to persuade robots to resist them. |

| A．Because children were not as clever as the adults. |
| B．Because robots reflected better than human beings. |
| C．Because robots in the presence made mistakes. |
| D．Because children wanted to affect the robots on purpose. |
| A．He is optimistic about the result. | B．He is worried about the future. |

【推荐2】A restaurant in northeast Thailand has become a center for traders of cryptocurrency. A cryptocurrency is a form of digital or virtual money that is not regulated by any central bank as it is based on a network and is independent of them.
HIP Coffee & Restaurant is a café that serves coffee and food. But it has set up screens showing the latest price information on cyptocurrency markets for its customers. The café also offers investment (投资) advice to go along with its coffee and cake.
Detnarong Satianphut is a 35-year-old cryptocurrency trader and a customer at the café. He said, “It’s exciting for me to be here because I get to meet people who share the same interests. We (traders) get to exchange information because in the trading world we are coming up against millions of people.”
Cryptocurrencies have started becoming more popular in Thailand. The latest official data suggests that as much as $7.62 billion in digital currency (货币) was traded in November.
In January, Thailand said it would start to watch over the use of digital currencies as payments. Officials warned of threats to the country’s economic system.
HIP café has been in business since 2013. The café began setting up its cryptocurrency information screens in 2020.
Since then, workers said the number of customers has doubled. HIP café’s boss is Okkhara Yongsakuljinda. He said the café provides a chance for people in the surrounding Nakhon Ratchssima province to invest. The café offers free investment advice and is planning on starting its own cryptocurrency coin.
Customers say trading in the café gives them the best chance of success in an uncertain market. The value of the most well-known cryptocurrency, bitcoin, recently dropped to a six-month low.

【推荐3】In recent years advances in medical technology have made it possible for people to live longer than in the past. New medicines and machines are developing every day to extend life.
However, some people, including some doctors, are not in favor of these life extending measures, and they say that people should have the right(权利) to die when they want. They say that the quality of life is as important as life itself, and that people should not be forced to go on living when conditions of life have become unbearable. They say that people should be allowed to die with dignity(尊严) and to decide when they want to die.
Others don’ t agree and say that life under any conditions is better than death and that the duty of doctors is always to extend life as long as possible. And so the battle goes on and on without a definite(明确的) answer.

【推荐1】Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.
