When was the last time you did something really fun with one of your parents—just the two of you?

    Parents who take their young children to music，swimming and art classes often stop arranging such activities once their kids are older and in school all day.But it doesn't have to be that way.Doing something enjoyable with your kids just might make you look at each other in a whole new way，especially if you do it through a class or an event.When parent and child become students together，it puts them on the same level，at least for a while.

“I really like parents to come to class with their kids—they start sharing things and talking about what they're doing and what they like，” said art teacher Pyper Dixon.

    However，finding something new in common is a big  choice for them，especially when kids get involved in sports and other after­school activities.But it's possible to learn a new skill or hobby together.

    That's certainly true of Lauren,11，from Silver Spring，who is in Dixon's class with her father，Dennis.“I was just going to drop her off，” Dennis said，“but Dixon persuaded me to stay.”

    Now Lauren gets to nag her father about doing his art homework.“He always leaves it to the last minute，” she said.“But then he'll turn around to do amazing drawings，”  she added.“We have different styles of drawing，so it's interesting  to talk it over with him.”

    Without the Saturday morning art class，Dennis said，he  would be reading the paper，and Lauren would be on her own in her room or on the computer.But they talk more now.“I can't think of an experience where you communicate with your kid so closely，” he said.

    Remembering names is an important social skill. Here are some ways to master it.

1）Recite and repeat in conversation.

    When you hear a person's name，repeat it.{#blank#}1{#/blank#}. You could also repeat the name in a way that does not sound forced or artificial.

2）Ask the other person to recite and repeat.

    You can let other people help you remember their names. After you've been introduced to someone，ask that person to spell the name and pronounce it correctly for you.{#blank#}2{#/blank#}.

3）Use associations.

    {#blank#}3{#/blank#} . For example，you could make a mental note: "Vicki Cheng -- tall, black hair. " To reinforce you're your associations, write them on a small card as soon as possible.

4）{#blank#}4{#/blank#}.

    When meeting a group of people, focus on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.

5）Go early.

    Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. {#blank#}5{#/blank#}. And as more people arrive, you can hear them being introduced to others—an automatic review for you.

A. Admit that you don't know.

B. Immediately say it to yourself several times without moving your lips.

C. There are fewer names for you to remember.

D. Limit the number of new names you learn at one time.

E. Link each person yon meet with one thing you find interesting or unusual.

F. Most people will be pleased by the effort you're making to learn their names.

G. You will be forgiven later.

    When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, skinny. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness( 头晕)that came with my poor diet, for those feelings meant that I was winning.

    As the season progressed, things had become tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn't listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice and games were becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet. She looked at me, disappointment in her eyes, knowing she couldn't make me stop, and walked away.

    A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach managed to say something nice about me. I realized then that I had ruined my senior year by being disrespectful, and I had probably ruined hers as well. So that evening I wrote her a letter apologizing and thanking her.

    Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, “Lynn Jones, how are you doing?” I looked up and saw the familiar face. “Thanks for the letter,” she said. “It meant a lot.” When I think of a coach, I think of someone above me, someone who gives instruction — not a friend. But Coach Smith is different, and, like any other good friend, she dealt with my problem in a determined way even when I hated her for it at that time. I didn't deserve her kindness, but she gave it anyway. I will forever be grateful for her help, and now for her friendship.

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.

    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

    So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.

    It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

    The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

    "This explains most of the previous failures of drug trials against rhinovirus," study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

    Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

    With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

At a snow park in Zhangiakou, Hebei, Chinese teenage snowboarder Su Yiming won a silver in the men's snowboarding competition on February 7, 2022. It was the first time that a Chinese snow boarder had ever competed in this event at any Olympics. 

Su was introduced to snowboarding at the age of 4 by his parents who were both snowboarding fans. Su fell in love with the sport the first time they took him to a ski center. Later he kept on practicing after class. To save up more time for snowboarding, he would get up at 5 a. m. and finish his homework early. Su just saw snowboarding as a hobby in the beginning. However, on July 31, 2015, when he knew that 2022 Winter Olympics would be held in Beijing, his mind tuned to professional (职业性的) competition. He dreamed of joining in the Winter Olympics. And he decided to go professional. 

In 2018. Su became a member of China's national snowboarding team. In 2020 and 2021, he took home gold medals (奖牌) in all national competitions. In January 2021, he became the first Chinese male snowboarder to finish the Cab 1800-one of the most difficult snowboarding skills. 

Behind his success is Su's hard work. He has made full use of every chance to train more. Usually he arrived at the training center earlier than his teammates. In that way, he could practice more. He even broke several snowboards in one week because of heavy training.
