Bursting into the classroom from recess, 15 children take their seats and face the woman they know as Ms. Yang.

    “What day is it today?” she asks, in Mandarin Chinese.

    “Confucius' birthday!” the fifth graders shout in Mandarin.

    “Why do we celebrate Confucius' birthday?”

    “Because he's the greatest teacher in the history of China!” exclaims a brown-haired girl. She is speaking Mandarin.

    English is rarely heard in Lisa Yang's class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin.

    The United States is actively trying to increase the group of students in “critical languages” such as Mandarin. The students at CAIS are way ahead in such a trend.

    Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.

    Mandarin Chinese is suddenly hot in American schools. As China becomes the world's leading economy sometimes this century, schools in the U. S. are scrambling to add Mandarin to their list of foreign languages or expand Chinese programs already in place.

    “It really is almost unprecedented. People are looking at China as a force to be reckoned with… And to ensure that the U. S. has the ability to conduct trade, and to work with the Chinese. Certainly having an understanding of Chinese language and culture is an advantage,” said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL).

    To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U. S.

    Robert Liu remembers his first two years in an American classroom It was not an easy adjustment. “In China, students respect their teachers,” he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.

    To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U. S.

    Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feeling can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm, reasonable way. Others burst with anger, losing control of themselves. But still other people control their anger. They cannot or will not express it.

    For years many doctors thought that controlling one's anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain lets out the same hormones that are produced during tense situations. They speed the heart rate, raise blood pressure, and narrow the blood vessels. In general, the person feels excited and ready to act.

    Doctors said that controlling these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger too often and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.

    Some doctors say that both controlling and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    For most people, Christmas is a time to relax in the company of family and friends. But for Santa Claus, and the thousands of fake Santas who impersonate（模仿） him every year, the Christmas season is time to get to work.

    Although Santa Claus waits until Christmas Eve to take his famous sleigh (雪橇) ride, Santa impersonators can be found at shopping malls around America throughout the six weeks leading up to December 25. "When you see Santa talking with kids at your local mall, that's when you know Christmas really is on the way," says Mary Lewine of New York City.

    With the excitement of Christmas, people often forget about the real people behind the red robes （长袍) and white beards, but being a mall Santa. is a tough job. "There is more to it than just sitting in a chair. There is more to it than just a red suit," said Timothy Connaghan, who has worked as a Santa for.38 years. "Children can really put the wear and tear on you.”

    A recent survey showed some of the challenges that mall Santas face every year. About 90 percent of Santas claimed that children pulled their beards to see if they were real, and 60 percent said that up to ten kids cough or sneeze on them every day. Even more disturbing, one-third of the Santas admit to having children wet themselves while sitting on their laps.

    So why would anyone take this job? For Ben Brauch, a retired high school teacher who has worked as a Santa for the last six years, the answer is simple-the children. "I see maybe 12,000 kids in a six-week period.

    It's hard work, but it's worth it because you get to play with kids." In fact, Brauch loves his job so much that he keeps his white beard long all year.

    My name is Clara. I still remember that chilly December day,sitting in science class. I'd finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye: NASA was holding an essay contest to name its Mars rover(火星探测器). Before I even knew anything else about it,a single word flooded my 11-year-old mind, Curiosity.

    I couldn't want for the bell to ring so I could get started on my essay.That afternoon, I raced home, sat down at the computer, and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone's mind...”

    Five months later, my mon received a phone call, and immediately, a wide smile spread across her face.

    On August 5,2012, at 10:31 p.m, the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.

    Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe. I remember as a little girl,my grandmother and I would sit together in the backyard for hours.She'd tell me stories and point out the stars,Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there, yet there was so much I didn't know about them.That's what I love so much about space.

    People often ask me why we go to faraway places like Mares.My answer is simple because we're curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what's over the hill and beyond the horizon.

    If you think your woman would never lie to you, guess again. From little 1 lies to the more serious variety, most women will hold back the 2 at some point in a relationship. Her motivation 3 lying can stem (起源于) from wanting to protect your feelings or, sure enough, to save her own butt (抵触).

    One day, when a seamstress（女裁缝师）was sewing 4 sitting close to a river, her thimble（顶针）fell into the river. When she cried out, the Lord 5 and asked, ‘My dear child, why are you crying?' The seamstress replied that her thimble had fallen into the water and 6 she needed it to help her husband in making a living for their family. The Lord dipped his hand into the water and 7 a golden thimble set with sapphires(蓝宝石).

    “Is this your thimble?” the Lord asked. The seamstress replied, ‘No.'The Lord again dipped into the river. He 8 a silver thimble.

    “Is this your thimble?” the Lord asked. Again, the seamstress replied, “No.”

    The Lord 9 down again and came up with a leather thimble.

    “Is this your thimble?” the Lord asked. The seamstress replied, “Yes.” The Lord was pleased with the woman's 10 and gave her all three thimbles to keep, and the seamstress went home, much 11 .

    Some years later, the seamstress was walking with her husband along the 12, and her husband fell into the river and disappeared under the water. 13 she cried out, the Lord appeared and asked her, “Why are you crying?”“Oh Lord, my husband has fallen into the river!”

    The Lord went down into the water and came up with George Clooney. “Is this your husband?”the Lord asked.

    “Yes” cried the seamstress. The Lord was 14. “You lied!” ”That is a(n) 15 !” The seamstress replied, ‘Oh, forgive me, my Lord. It is a 16. You see, if I had said ‘no' to George Clooney, you would have come up with Brad Pitt. Then if I said ‘no' to him, you would have come up with my husband. Had I then said “yes,” you would have given me 17. Lord, I'm not in the best of health and 18 be able to take care of all three husbands, 19 THAT'S why I said “yes” to George Clooney.'

    And so the Lord let her keep him.

    The 20 of this story is: Whenever a woman lies, it's for a good and honorable reason, and in the best interest of others.

在2020中国国际服务贸易交易会上，由国药集团中国生物技术股份有限公司（中国生物）旗下北京生物制品研究所、武汉生物制品研究所和科兴控股生物技术有限公司（科兴）研发的三款新冠灭活疫苗，首次亮相服贸会展位。

美媒《财富》杂志承认，中国疫苗研发公司正处于全球研发竞赛的“头位”，占据目前9个处于第三期疫苗研发项目中的5个。但《财富》的报道也暗示中国在未结束三期临床试验前就安排紧急接种的做法“非传统”“可能有问题”，是“为了争夺第一名”而“挑战极限”。法新社形容疫苗是“游戏规则改变者”，并在标题直接打出“中国首次炫耀新冠病毒疫苗”。也有外媒对于中国的疫苗研发给出客观评价。西班牙埃菲社认为：“目前来看，中国将是最早掌握新冠病毒疫苗的国家之一。这表明其科研能力可以比肩世界上技术最先进的国家。”路透社认为，数据显示科兴的疫苗似乎是安全的，虽然在老年人当中效果略弱。

《吊魏武帝文》序

陆机

元康八年，机始以台郎出补著作，游乎秘阁，而见《魏武帝遗令》，忾然叹息，伤怀者久之。

客曰：“夫始终者，乃物之大归；死生者 ， 性命之区域。是以临丧殡而后悲，睹陈根而绝哭。今乃伤心百年之际，兴哀无情之地，意者无乃知哀之可有而未识情之可无乎？”

机答之曰：“夫日食由乎交分，山崩起于朽壤，亦云数而已矣。然百姓怪焉者，岂不以资高明之质，而不免卑浊之累；居常安之势，而终婴顷离之患故乎？夫以回天倒日之力，而不能振形骸之内；济世夷难之智，而受困魏阙之下。已而格乎上下者，藏于区区之木；光于四表者，翳乎蕞尔之土。雄心摧于弱情，壮图终于哀志；长算屈于短日，远迹顿于促路。呜呼，岂特瞽史之异阙景，黔黎之怪颓岸乎？”

观其顾命冢嗣，贻谋四子，经国之略既远，隆家之训亦弧。又云：“吾在军中，持法是也。至小忿怒、大过失，不当效也。”善乎，达人之谠言矣。持姬女而指季豹以示四子曰：“以累汝。”因泣下。伤哉曩以天下自任今以爱子托人同乎尽者无馀而得乎亡者无存然而婉变房闼之内绸缪家人之务则几乎密与！又曰：“吾婕妤妓人，皆著铜爵台。于台堂上施八尺床，繐帐，朝晡上脯糒之属。月朝十五，辄向帐作妓。汝等时时登铜爵台，望吾西陵墓田。”又云：“馀香可分与诸夫人，诸舍中无所为，学作履组卖也。吾累官所得绶，皆著藏中。吾馀衣裘，可别为一藏。不能者，兄弟可共分之。”既而尽分焉。亡者可以勿求，存者可以勿违。求与违，不其两伤乎？悲夫！爱有大而必失，恶有甚而必得。智惠不能去其恶，威力不能全其爱 ， 故前识所不用心，而圣人罕言焉。若乃系情累于外物，留曲念于闺房，亦贤俊之所宜废乎？于是遂愤懑而献吊云尔。

—It couldn't be worse. We were held up on the expressway for three hours. On the way back, we found the car got a f tyre, and the spare was, too.

    Swedish businessman Nile Bergqvist is delighted his new hotel, the world's first igloo(冰屋) hotel.

    (build) in an small town, it has been attracting lots of visitors but soon the fun will be over. In two weeks' time Bergqvist's ice creation (be) nothing more than a pool of water. “We don't see it as a big problem, ”he says. “We just look forward to (replace)it. ”

    Bergqvist built his first igloo in 1991 for an art exhibition. It was successful that he designed the present one, measures roughly 200 square meters. Six workmen spent more than eight weeks piling 1,000 tons of snow onto a (wood) base；when the snow froze, the base was removed.

After their stay, all visitors receive a survival certificate recording their success. With no windows, nowhere to hang clothes and temperatures 0℃, it may seem more like a survival test a relaxing hotel break. “It's great fun,” Bergqvist explains, “As well as a good start in survival training.''

    The (popular)of the igloo is beyond doubt：it is now attracting tourists from all over the world. At least 800 people have stayed at the igloo this season even though there are only 10 rooms.
