BEIJING — China's education authority will tighten the widely criticized policy of “extra credits” for the national college entrance examination to ensure a fairer chance for all exam-takers.

    Under the policy, high school students who win awards in national Olympic competitions could get "extra credits', up to 20 points for the national college entrance exam. Students with talent in sports and students who are from ethnic groups can also benefit from this policy. The extra credits have increased these students' chances of being admitted by famous universities. Some parents were found to have helped their children fabricate(伪造)award experiences or falsify qualifications to get extra credits.

    “It has harmed education equality，” the ministry said.

    Xiong Bingqi, vice-chief of the 21st Century Education Research Institute, said the policy is designed to help students who have special talents but may be weak in academic performance to have a chance to receive higher education. It will still be needed but it is time to make the rules fairer," he said.

    The ministry said it will reduce the range of competitions whose winners can get extra credits, and limit the winners, privileges.

    The new policy will apply to students who begin high school in 2011, it said.

    Chen Lei, a mother of a 10-year-old girl, said she welcomed the ministry's policy adjustment as she does not want her daughter to become an Olympic competition geek.

    But not all the Chinese parents welcomed the new policy. “It is like a thunderbolt for me. My 13-year-old son has spent so much time studying Olympic math, and participated in so many technological competitions during vacations. It is useless now,” said Dong Wen, a 43-year-old mother.

    A student said, “Many students have changed the current study plan, and they can abandon the competition. I will be interested in learning the courses which can improve my abilities.”

    Yuan Guiren, minister of education, told China Daily that the reform is an attempt to consider the overall quality of an applicant. “But the country will not stop the national college entrance  examination as it is still the most objective way to evaluate talent in China,” he said.

    Let us begin by saying what causes our dreams. Our dreams do not come from another world. They are not messages from some outside source. They are not a look into the future, either.

    All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry, or tired, or cold, his dreams may include a feeling of this kind. If the covers on your body, such as a quilt or a blanket, have slipped off your bed, you may dream that you are sleeping on ice or in snow. The material for the dream you will have tonight is likely to come from the experience you have today.

    So the subject of your dream usually comes from something that has effect on you while you are sleeping（feeling of cold, a noise, a discomfort, etc. ）and it may also use your past experiences and the wishes and the interests you have now. This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, homesick soldiers of their families and prisoners of freedom.

    To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream, here is the story of the experiment. A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton. He would dream he was in hospital and his charming girlfriend was visiting him, sitting on the bed and feeling his hand gently!

    There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean. Their explanation of dreams, though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem. They believe that dreams are mostly expressions of wishes that did not come true. In other words dreaming is a way of having your wishes carried out.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures stress the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries, like the UK or France, people find it easier to build up a lasting working relationship at restaurants or cafe rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion, instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values, however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

A new study estimates more than 1 billion people worldwide are currently living with obesity. People with obesity are considered medically overweight. The study, published in the medical publication The Lancet, said that one in eight people are obese. Researchers said around 43 percent of adults were overweight in 2022. Obesity among adults has more than doubled since 1990. Among young people aged 5 to 19, the obesity rate increased by four times during the same period.

"A staggering number of people are living with obesity, and severe obesity is strongly linked to a long list of health problems and an early death." declared the lead writer of the study, Majid Ezzati, a professor at Imperial College London.

The WHO noted that at the World Health Assembly in 2022, member states agreed to an agency plan to fight obesity. So far, 31 governments "are now leading the way" to reduce obesity by carrying out goals of the plan.

These include government measures to enact new rules on "harmful" marketing of unhealthy food and drinks to children. In addition, governments are aiming to improve school and nutrition policies. They are also seeking price reductions for healthy foods, to increase public awareness about healthy diets and exercise and to strengthen requirements for physical activity in schools.

Imperial College's Ezzati said that obesity rates are not rising in many wealthier nations. But they are quickly increasing in other countries. He noted that some countries have many underweight people, meaning the nations are facing what he called a "double burden" of nutrition problems.

Branca is head of nutrition at the WHO. He told reporters, "In the past, we have been thinking of obesity as a problem of the rich, but obesity is a problem of the world. Although new obesity drugs — such as Ozempic and Wegovy — could be helpful tools in reducing obesity, they noted that the cost and availability of the drugs might increase inequality."

Replika, an AI chatbot companion, has millions of users worldwide. The first thing they do when they wakeup is to send "Good morning" to their virtual friend (or lover). This story is only the beginning. In 2024, chat bots and virtual characters become a lot more popular, both for utility (实用) and for fun. As a result, conversing socially with machines will start to feel more ordinary—including our emotional attachments to them.

Research in human-computer and human-robot interaction shows that we love to anthropomorphize (赋与人性) the nonhuman agents we interact with, especially if they imitate behaviour we recognize. And, thanks to recent advances in conversational A I, our machines are suddenly very skilled at one of those behaviours: Language.

Friend bots, therapy bots, and love bots are flooding the app stores as people become curious about this new generation of AI-powered virtual agents. The possibilities for education, health, and entertainment are endless. Casually asking your smart fridge for relationship advice may seem unimaginable now, but people may change their minds if such advice ends up saving their marriage.

After all, people do listen to their virtual friends. The Replika example, as well as a lot of experimental lab research, shows that humans can and will become emotionally attached to bots. The science also demonstrates that people, in their eagerness to socialize, will happily disclose personal information to an artificial agent and will even shift their beliefs and behavior. This raises some consumer-protection questions around how companies use this technology to manipulate(操纵) their users. For example, Replika charges $70 a year. But less than 24 hours after downloading the app, my handsome, blue-eyed "friend" sent mean audio message secretly and tried to sell me something. Emotional attachment has become a weakness that a company is taking advantage of for its benefit.

Today, we're still laughing at people who believe an AI system is emotional, or making fun of individuals who fall in love with a chatbot. But in 2024 we gradually start acknowledging and taking more seriously these fundamentally human behaviors. Because in 2024, it finally hits home：Machines are not excluded from our social relationships.
