In England, people often talk about the weather because they can experience (经历) four seasons in one day. In the morning the weather is warm just like in spring. An hour later black clouds come and then it rains hard. The weather gets a little cold. In the late afternoon the sky will be sunny, the sun will begin to shine, and it will be summer at this time of a day.       

    In England, people can also have summer in winter, or have winter in summer. So in winter they can swim sometimes, and in summer sometimes they should take warm clothes.     

    When you go to England, you will see that some English people usually take an umbrella (伞)or a raincoat with them in the sunny morning, but you should not laugh at them.     

    If you don't take an umbrella or a raincoat, you will regret (后悔) later in the day.     

    In February, 2015, a South Korean woman was sleeping on the floor when her robot vacuum ate her hair, forcing her to call for emergency help. It surely isn't what Stephen Hawking warned us that intelligent devices “mean the end of the human race”. But it does highlight one of the unexpected dangers of inviting robots into our home.

    There are many examples of intelligent technology going bad, but more often than not, they involve cheating rather than physical danger. Meanwhile, increasing evidence suggests that we, especially children, tend to tell our deepest, darkest secrets to human robots. So how do we protect ourselves from giving-away code?

    Once you've invited a robot into your home, you need to manage your expectations. Movies and marketing may have told us to expect deep interaction with robots friends but we've still got a long way to go before they are as socially aware as described. Given the gulf between expectation and reality, it's important to avoid being tricked.

    The message is clear: as robots became increasingly connected to the internet, and able to respond to natural language, you need to especially cautious about figuring out who or what you are talking about.

    We also need to think about how information is being stored and shared when it comes to robots that can record our every move. Some recording devices may have been designed for entertainment but can easily be adapted for more dangerous purposes. Take Nixie, the wearable camera that can fly off your wrist at a moment's notice and take shots around you in the air. It doesn't take much imagination to see how such technology could be taken advantage of.

    If the technology around us is able to record and process speech, images and movement, or listen secretly to us, what will happen to that information? Where will it be stored? Who will have access?

    So, what is the safest way to welcome robots into our homes, public spaces, and social lives? We should be cautiously optimistic that intelligent machines could become enriching companions, while acknowledging that we need to determine strict boundaries for robots. There should be someone to turn to should your robot commit a crime, steal your card... or try to eat your hair.

    If you don't use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means he does not give it enough chance to become strong.

    If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault. Have you ever found that some people can't read or write but usually they have better memories? This is because they can not read or write and they have to remember things; they can not write down in a little notebook; they have to remember days, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: practice remembering.

    Traditional Chinese Medicine (TCM) needs to prove its worth through rigorous clinical trials, according to the head of one of China's largest herbal remedy companies, as a contentious new law to boost the $40bn sector comes into effect.

    Traditional Chinese Medicine is estimated by analysts to account for a third of sales in China's $117bn pharmaceutical (药学) market, the world's second largest. But most of those sales are of relatively cheap over-the-counter drugs, with many Chinese hospital doctors unwilling to prescribe TCM remedies because of the lack of evidence for their effectiveness.

    China's first law promising equal status for TCM and western medicine in the country's state-dominated healthcare system comes into effect this weekend. Provisions include encouragement for hospitals to set up TCM centres, and a licensing system for practitioners (从业者). "This law is very important for securing the status of TCM," said Wu Yiling, chairman of Yiling Pharmaceutical, a company that makes herbal remedies based on traditional recipes in the northern province of Hebei.

    Listed in Shenzhen, Wu Yiling has a market capitalization of RMB 20.7bn ($3bn). Mr Wu, the son of a herbal practitioner, controls a family fortune of $1.6bn, according to the Hurun Rich List.

    Mr Wu is both a supporter of the nature of Qi—the mystical energy force that provides the basis for much of TCM theory—and the clinical trials vital to western pharmaceutical companies. "TCM needs to develop using modern research methods," he said.

    For instance, researchers from Peking and Cardiff Universities tested the health benefits of Yiling's herbal medicine Yangzheng Xiaoji, publishing papers in the International Journal of Oncology that showed the drug can slow the growth of cancer tumours. "The theory and recipe is TCM, but in practice the evaluation of our medicines is carried out according to western evidence-based methods," Mr Wu said.

    Analysts say such tests can help gain support from doubtful hospital doctors and boost prescriptions. "Doctors need strong evidence that drugs definitely work," said Serena Shao, healthcare analyst at brokerage CLSA. "Some of these companies are currently doing clinical trials, and getting proof that their drugs have the same efficacy (功效) as chemical drugs. That's the way to go." she added.

    The TCM law has been greeted with doubt from China's western-schooled medical establishment, which points to a lack of rigorous training for TCM doctors, and a recent series of shocking events involving herbal injections believed to have been harmful. "Officials will try and encourage TCM, but also will be very cautious about what kinds of TCM they use in hospitals," added Ms Shao.

    Failure is an unavoidable part of life. Though science has named some life skills that promise success, we're told over and over again that no great success was ever achieved without failure -- or many failed attempts. One of life's most important lessons, therefore, has to be how to handle failure best. But what is the message?

    For starters, ignore advice from anyone that tells you, "Don't beat yourself up about it," no matter how well-meaning they are. According to the new research from the University of Kansas, we absolutely should be beating ourselves up when we fail. Marketing professor Noelle Nelson and her team found that the more emotional a person's response is to failure, the more likely they are to achieve better results the next time they deal with a related task.

    The researchers carried out two experiments in which undergraduate students were required to perform specific tasks. In one experiment, they were asked to search online for a squeezer and report the lowest price they could find with the possibility of winning a $50 cash prize. However, the task was controlled, and all participants were told (by a computer) that the lowest price was $3.27 less than their reported price. Consequently, no participant won the cash prize. When the results were announced, some participants were asked to focus on their emotional response, and others on their cognitive (认知的) response. During the next similar task, participants who focused on their emotional response to failure made more effort than those who focused on a cognitive response.

    Everybody has their own unique challenges, responsibilities, duties, and projects, but these findings are related to all of us. Your personal failure may be a cake that fails to rise, a presentation that goes wrong, or a deadline that gets missed—it doesn't matter. What matters is how you react to it. Instead of thinking about the failure, let yourself feel bad about it. Then follow this advice on how to bounce back after your failure.

Zach Conti, who is a student in Eastern Michigan University and joined the football team as a walk-on (临时队员) in 2020, has worked at several part-time jobs to pay for his education. Now he won't have to anymore.

"Football is something I really love, so ever since I got to school, I've had to do whatever it takes to stay here and stay in a good position with my studies and football," Conti said. "I have to do many jobs, but when you really want something, you won't feel bored."

While Conti's teammates would see him going to or coming back to work, they were very supportive. But Conti still had trouble paying for his education and his mother's medical bills. He was planning on leaving the university.

Brian Dooley, who would get a scholarship, couldn't see that happen and decided to help his teammate. He told head coach Chris Creighton about the thing. Creighton went to see if an additional scholarship could be given out. The school allowed the team to give out five scholarships and another one was not allowed. Then Dooley went to the coach with a special request.

"Brian Dooley comes into my office," Creighton said during a team meeting on August 3. "And he says, ‘Coach, Conti should get a scholarship. And I've talked this over with my family. And if there's a way to make this happen, I am willing to give up my scholarship as a gift to Conti.'" That's when Dooley walked over to Conti and handed him an envelope with the scholarship inside.

Dooley explained the reason for helping his teammate "I did it because I've seen Conti grow over the long time. It would be a great pity if he walked away from something that he loves. He works so hard. In my eyes, he should get it 100 percent."
