New friends. Fresh lifestyle. Better career opportunities…Those are attractions of overseas study for young people in China. “Start early, finish strong,” some of them say.

    More than 300 universities from 27 countries and regions were represented at last weekend's international education exposition(展览).

Are we alone in the universe? A team of scientists announced on January 6, 2015 that they had identified eight planets beyond our solar system, three or four of which orbit in their stars' "Goldilocks Zone" — the region where temperatures are not too hot or too cold for water, which is a necessary ingredient for life as we know it, to exist liquid form. This may be good news for people hoping that Earth is not the only inhabited world in the universe.

    The scientists, led by Dr. Guilermo Torres of the Harvard-Smithsonian Center for Astrophysics, made the discoveries using data collected by the planet-seeking Kepler telescope.

    NASA launched Kepler in 2009. Since then, the telescope has identified more than 1,000 planets outside of our solar system. Torres and his team analyzed the data about the eight newly discovered world to determine which ones are most likely to be similar to our Earth.

    Among the new discoveries, the scientists say the planets called Kepler438b and 442b are the closest to Earth. Kepler 438b is just about 10% larger than our planet, and gets 40% more of its energy from its star than Earth receives from the Sun. Temperatures there would be about 140 degrees. Kepler 442b is about 33% larger than Earth, but receives 30% less energy from its star. That would make it a potentially chillier world than our own. Torres says it is possible for life to exist and survive in either of those temperatures, but for that to happen, these planets would need to have another key ingredient for life: a heat-trapping atmosphere like Earth's.

    While these findings add to the possibility that life exists beyond Earth, Torres cautions against drawing conclusions, “We are not claiming they are inhabited,” he says. In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unknown whether these planets contain life. But the discovery of planets in their stars' habitable zones suggests that somewhere out there, some form of alien life may have taken hold.

    Can you remember the day when you spoke your first word? If you can, you are unusual. Try to imagine what first few months of your life were like. I am sure you just spent most of your time eating, sleeping and crying. As you grew older, you were awake more of the time. It took your parents more time to play with you and talk to you. You watched and listened curiously (好奇). You began to know that people made certain sounds to go with certain things.

    Then you began to try making the sounds you heard. And step by step you were able to make the right sound for one thing. On that day you came to understand the secret of language. The secret is that a certain sound means a certain thing. One sound might be as good as another. But it is no good as a word unless everybody agrees on its meaning. Only when a group of people use the same set of sounds of things, can they understand each other. Then, and only then do these people have a LANGUAGE.

    After you found the secret of language, you learned words. Some of the words meant things, such as BOOKS, CHAIRS and SHOES. Some words meant doing things, such as GO and SWIM, and other words describe things, such as GOOD and DIRTY. Soon you learned to put words together to express your idea, such as “I want to go out and play with my friends.” This is language. By means of language people can communicate. So we say languages are means of communication.

    In 2012, Kim Stemple, a special-education teacher, found herself in a Boston hospital being treated for one of several diseases she had been diagnosed(诊断) with, including lupus and lymphoma. The normally confident Stemple was naturally getting very depressed. And then a friend gave her a medal.

    Before she got too sick to exercise, Stemple had been a marathon runner. The medal came from a racing partner who had just finished a half marathon in Las Vegas and hoped the souvenir would act as a kind of feeling pick-me-up. It worked like a charm­and then some.

    After Stemple hung the medal near her hospital bed, other patients said they wanted medals too. That got Stemple thinking. "A medal is a simple way to give a positive message," she told pilotonline.com. And so was born her charity, We Finish Together, which collects medals from strangers­runners, dancers, swimmers, singers, and even spelling bee winners-and donates them to all sorts of people in need.

    Those who received the medals have included hospital patients, residents of homeless shelters, and veterans. Part of the process involves the donor writing a personalized note on the ribbon. "This gives them a connection to someone," says Stemple. "If they receive a medal, they know someone cares."

    Can a simple medal really make a difference? Yes, says Joan Musarra, who suffers from pulmonary fibrosis. "I opened my package containing my new medal and the notes of positive, warm thoughts, I was overwhelmed," she wrote to Stemple. "At that moment, I was sitting on my couch breathing through life-support machine because my lungs have been worsening so badly. It means so much to me to feel that I am not alone."

    What will restaurants look like in the future？What would your dinner taste like if a robot cooked it？A robot restaurant in Tianjin may give you the answers.

    Covering an area of over 400 square meters with a total of 112 seats, the X Future Restaurant is a robot restaurant opened in November 2018. The restaurant has amazed customers with its fully-automated(全自动的)technology, which covers every step of the dining experience, from ordering to cooking to serving the dishes and even taking payment.

    Entering the restaurant, one can order dishes by simply scanning(扫描)the QR codes on the table. There are over 40 choices of dishes. After taking the order, "robot cooks"prepare dishes using fixed time, temperature and ingredients designed by famous Chinese cooks.

    "As the cooking is controlled by a computer system, the taste and quality of dishes can be good, "said Li Xiaokui, manager of the X Future Restaurant.

    Robots also complete the delivery of dishes. Without following any designed route, the robot waiters serve meals thanks to automated driving technology, which helps each robot timely change its route when something is in the way.

These eye-catching technologies have received wide praise from customers. "The dishes taste surprisingly good. I couldn't believe that they were made by robots, especially dishes that were difficult to cook" one customer said. "The application of robots has increased our efficiency(效率)and cut down our costs, "Li said, "I think robot restaurants will develop fast and have a bright future. "

The last few days before Christmas passed quickly and it was soon Christmas Eve. That night when everyone went to bed, Bunny couldn't sleep. He still couldn't think of what he wanted his Christmas gift to be. He wondered how Father Christmas would know what to bring him if he didn't know himself.

As he was sitting up in bed, Bunny heard a big noise on the roof (屋顶) and a sound downstairs. It was Father Christmas, he realized. Bunny jumped out of bed and raced down the hall to the stairs hoping to have a look at the old man with his own eyes.

By the time Bunny reached the bottom of the stairs, though, everything was again silent. Beautiful gifts were piled (堆积) under the Christmas tree, but Father Christmas was gone. He looked for him for a few minutes, but it was already too late. Bunny turned to climb back upstairs when he heard a cry.

"Hello," said Bunny. "Is anybody there? "

He was answered by another cry. Bunny looked around the big pile of gifts to see what was making the noise. Right under the tree was a funny looking brown animal with big feet and sad eyes. Bunny might have mistaken it for a dog, if it hadn't been for the antlers (鹿角) on its head.

"Are you a reindeer (驯鹿)?" asked Bunny.

"Yes," replied the animal. "My name is Ralph."

"And you were pulling Father Christmas's sled (雪橇)?"

"I was until I got airsick (晕机), " replied Ralph. "I'm afraid I wasn't cut out for the job. Now I'm stuck here and I don't know how to get back to the North Pole."

"Well, if you like, yon can stay with us as a friend," said Bunny. As he made the offer, Bunny suddenly realized the gift he wanted from Father Christmas was a new friend!
