Jack threw some papers on my desk and looked at me angrily. “What's wrong?” I asked. “Next time you want to change anything, ask me first,” he shouted and left.

    “How dare he treat me like that?” I thought. I had just changed one long sentence, and correct grammar—something I thought I was paid to do. In fact I had been warned. On the first day one of  my workmates took me aside and reminded me of his temper. As the weeks went by, I came to look down on Jack.

    One day Jack's other papers left me in tears so I stormed into his office angrily. “What?” he asked.

    Suddenly I knew what I must do. After all, he earned it. “Jack, the way you've been treating me is wrong. I've never had anyone speak to me that way. As a professional, it's wrong for me to allow it to continue,” I said. Jack smiled nervously, “Susan, I make you a promise that I will be a friend. I will treat you as you should be treated, with respect and kindness,” he said. With these words, I left.

    Jack avoided me the rest of the week, and never questioned my work again. I brought cookies to the office one day and left some on his desk. Another day I left a note: “Hope your day is going great.” Over the next few weeks, Jack reappeared , but there were no more Jack's papers. One year later I discovered I had breast cancer, and was scared. The statistics (统计数字) were not great for my long-term survival.

    On the last day of my hospital stay, Jack came and silently handed me a bundle with several bulbs inside. “Tulips (郁金香) ,” he said. I smiled, not understanding. He cleared his throat. “If you plant them when you get home, they'll come up next spring. I think you will be there to see them when they come up.” Tears clouded my eyes and I whispered: “Thank you.”Jack held my hands firmly, saying, “You are welcome. You can't see it now, but next spring you will see the colors I picked out for you.”

    I have seen those red and white striped（有条纹的） tulips push through the soil every spring for over ten years now. This past September the doctor declared me cured. At a moment when I was praying for just the right word, a man with very few words said all the right things. After all, that's what friends do.

    China has been drinking tea since the time of Shennong, 5,000 years ago. Britain's relationship with tea is much shorter, but tea enjoys the pride as the UK's national drink. According to the UK Tea Council, British people drink an average of three cups a day or a national total of 165 million cups every day.

    With figures like these, it is no surprise that time spent taking tea affects the working day in Britain. A recent survey found that 24 minutes a day are lost to making, buying and drinking tea and coffee. That is, £400 a year is lost in working hours per employee, or 190 days over a lifetime. So, should employers be worried about this lost working time, or does the tea break make up in other ways?

    One argument is that caffeine(咖啡因) improves mental state: a drink of tea or coffee can make you active and focus on work.

    Professor Rogers of the University of Bristol disagrees. After years of studying caffeine he sees nothing can prove that. “Workers would perform equally well if not drinking it at all,” he says. “But if they're often drinking it and then go without, they'll feel tired and won't perform well.”

    Occupational Psychologist Cooper instead emphasizes the role tea breaks play in sedentary (久坐的) office life, and in building social relationships. “We need to make people more active and see other people. The tea break is one way of doing this,” says Cooper.

    And Professor Rogers also points out the comfort effect of a hot drink: “We warm our hands on them on a cold day; they're comforting and play a big role in our everyday life. Whatever the caffeine's doing, I'd say these 24 minutes aren't wasted.”

    “Helicopter parent” may not sound pleasant, but given the chance, most parents would probably prefer a vehicle to zoom (快速移动)little ones between school, football practice and piano lessons. Getting children where they need to go is a huge task and expense, especially in homes where both parents work. Hailing rides (专车服务)through firms like Uber and Lyft has made life more convenient for adults. But drivers are not supposed to pick up kids who travels without an adult aside (although some are known to bend the rules).

    Children represent a fresh-faced opportunity. Ride-hailing for kids could be a market worth at least $50bn in America, hopes Ritu Narayan, the founder of Zum, one of the startups in want of the prize. These services are similar to Uber's, except they allow parents to schedule rides for their children in advance. Children are given a code word to ensure they find the right driver, and parent sreceive warnings about the pick-up and ride, including the car's speed. These services promise more careful background checks finger printing and training than typical ride-hailing companies.

    Annette Yolas, who works in sales at AT&T, says that she spends around $200 a month on Hop Skip Drive, a service that operates in several markets in California, for her three kids to get to the school bus on time and to ballet practice. She says it has been a “life-saver” by allowing her to work longer hours. Meanwhile, kids avoid the embarrassment of a relative pulling up at school. But ride-hailing firms for kids may end up like the children in Neverland, and never fully grown. They face several challenges. One is finding enough drivers. All users need rides during the same limited set of hours: before and after school, which makes it hard to offer drivers enough work. It can also be challenging to persuade parents, who have drilled it into children never to get in a stranger's car.

    And while ride-sharing companies can annoy adult passengers by cancelling or being late, such behavior can be a disaster when children are involved. Shuddle, an early entrant in the taxis-for-kids business, which shut down in 2016, had only two out of five stars on Yelp (点网站)for that reason， and lots of negative reviews from parents. It had made money on rides mainly by raising prices ever higher.

    Shuddle's failure has not discouraged Uber itself, which is expected soon to launch a pilot programme for teenagers under 18. Parents may be happier to use services they are familiar with. But Uber's entrance is likely to add to the struggle of child-focused ride-hailing businesses as they compete for customers and new funds.

    A primary school in Jinhua, Zhejiang Province has announced it no longer requires parents to sign their children's homework, which was aimed at getting parents to supervise(监督) their children after school. China Youth Daily comments: Putting an end to the requirement that parents sign off on the homework of their children eases the burden on many parents, as otherwise they would have to do primary school homework after a hard day's work. But there are worries that if parents stop having to sign off on their children's homework, the children will not get good grades.

    However, the most effective way for children to study is to develop their willingness to learn and do their own studies. When doing homework, students practice and hopefully apply what they have learned. It is true that teachers are supposed to check students' homework and identify their mistakes. But some parents correct their children's mistakes by themselves when signing off on it.

    It is the duty of students to do their homework, be responsible for their studies and correct their mistakes. Parents' supervising their homework, checking their answers and dealing with the harder problems will only make children less aware of their mistakes and encourage them to wait for their parents' help when they face any problems.

    Children have to manage their own learning and develop the ability to study by themselves, as competence will not be achieved if a student simply repeats strict tasks in which he is assisted in school by teachers and at home by parents.

    A delayed satisfaction experiment conducted by Walter Mischel in the 1960s proved that children with better self-discipline(自律) performed better in their studies and interpersonal relationships.

    There is little doubt that parents' supervision can make children's homework better. But it does not give children the chance to practice their ability to solve problems independently.

    Why does time seem to fly by faster as we get old? You've got your aging brain to blame. This is likely due largely to the physical changes of our nerves and neurons (神经元). New research suggests 'rapid fire' abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information.

    The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知觉) of time as we get old. Over the years these structures become more complex and eventually begin to degrade.

    "Little babies, for example, move their eyes much more often than adults because they're processing images at a faster rate," Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they're happening more quickly.

    Physical education, or PE, isn't required for all high school students. In some schools, it isn't offered for some different reasons. But should high school students have physical education? The answer is certainly "yes".

    Today many people don't do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

    High school isn't that easy. Many students are under a lot of stress. Stress can be harmful to a student's studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

    The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖症). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don't get teens to move around, such as video games and computer activities, means many teens don't get their required exercise. PE classes act as a public health measure to encourage physical activities and help teens have healthy weights.

    Not doing sports increases teens' risk of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be hindered by lifestyle changes, according to the American College of Sports Medicine.

    According to the President's Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
