It is December 25th, 2050. The people in the city are all celebrating Christmas. I'm the mayor of our city. My citizens and I are holding a big party under the sea, though you wouldn't believe it. But please do not feel excited, you should feel sad because we have to live under the sea. Because of the pollution, the earth has been completely destroyed, from top to bottom. The atmosphere has no oxygen and moisture. As a result, the plants are burned by the strong sunlight with a great number of harmful rays. Of course, none of them are still alive. Not only no green, but also the temperature reaches about 121℃ all day even in winter because there is too much CO2 circling the earth.
On the land, there is no life. Luckily, the sea is not destroyed by human. So, we have to move into the sea. At the bottom of the water, people have built many new cities. There is a lot of advanced* equipment in each city. Computers are used to control all the machines, even the people's life. We can also make the seawater into fresh water. There are two machines making oxygen. If they stop working for only one minute, more than 10 million people will die.
The population of our city is over 30 million and, of course, it is quite crowded. We have lots of high buildings and bridges. The roads are wide, too. Our cars are miniature UFOs, don't be surprised, it is true. At the bottom of the sea you can't see anything, because there is no light all day. However, we have advanced lighting equipment so that we can see the "sun"under the sea. Of course, the advanced lighting equipment is very expensive. And if it doesn't work, we can see nothing under the sea. What should we do then?

A Friend Saves Your Life

    In the United States，every year, Thanksgiving Day is on the fourth Thursday of November．People in Canada also celebrate Thanksgiving Day. But because Canada is in the north of the United States，so it is colder and the harvest comes earlier in the year．In Canada，people have Thanksgiving Day on the second Monday of October．

    The harvest brings a lot of food to people．On Thanksgiving Day people in Canada and America like to have a big meal with their friends and family just like what Chinese people do at Mid-Autumn Festival．Many Canadians and Americans put flowers，vegetables and fruits around their homes．

    At a Thanksgiving Day dinner, many Canadians and Americans will eat turkey, potatoes and pumpkins pie．These are food like the food of many years ago．They are saying “Thank you” for the harvest that comes every year．

    “Cool” is a word with many meanings. Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings. “Cool” can be used to express feelings of interest in almost everything.

    When you see a famous car in the street, maybe you will say. “It's cool.” You May think, “He's so cool,” when you see your favorite football player.

    We all maximize(扩大)the meaning of “cool”. You can use it instead of many words, such as “new” or “surprising”. Here's an interesting story we can use to show the way the word is used. A teacher asked her student to write about the waterfall(瀑布) they had visited. On the student's paper was just the one sentence, “It's so cool.” Maybe he thought it was the best way to show what he saw and felt.

    But the story also shows a scarcity(缺乏)of words. Without “cool”, some people have no words to show the same meaning. So it is quite important to keep some credibility(可信度).Can you think of many other words that make your life as colorful as the word “cool”? I can. And I think they are also very cool.

    When 4-year-old Prince George started his first day of school in September. Chinese language was on his curriculum(课程).

    And he wasn't alone. It is reported that about 51 percent of the parents in the UK want their children to learn Chinese, as it's believed to be one of the most useful languages to know.

    In the popularity of Chinese drove the UK government to start the Mandarin Excellence Programme in September last year. It aims to make at least 5.000 British state secondary school students be good at speaking Chinese by 2020.

    Yet, the UK isn't the only country showing a growing interest in Chinese.

    The language has become the second most spoken foreign language in the United States this year, after only Spanish, with over 2.1 million speakers.

    Many US famous people such as Facebook founder Mark Zuckerberg and Malia Obama, former US president Barack Obama's daughter, study Chinese as a second language.

    So far, 67 countries and regions have included Chinese in their national curriculum. So why are so many countries enthusiastic about learning Chinese?

    One reason could be that as China continues to develop rapidly. Chinese is increasingly becoming a useful tool for people's personal and professional growth.

    "I think everyone believes that Chinese will be the next great superpower…even if it's not a superpower like America. It's still very important." Aisling from Germany, who studied at the Renmin University of China, told Xinhua News Agency.
