    MinecraftEDU, a video game with which you can build virtual (虚拟的) worlds, will be used in the classroom. Microsoft bought the game Minecraft from its Swedish creator for 2.5 billion dollars. Now, the software company wants to offer schools a special educational version(版本).

    MinecraftEDU is an add-on to the game, which is specially created by teachers for classroom use. While thousands of classes around the world are already using Minecraft in their lessons, Microsoft wants to make it easier for schools to use the software.

    Minecraft is a game that can be used in many subjects, including maths, science and geography. Microsoft wants to add new features to the educational version, for example, letting students take photos and putting them into an online diary. The new version will allow children to download the game at home without having to pay more money for it. Microsoft is expected to ask students and teachers for about five dollars a year to use the game in school and at home.

    According to Microsoft, Minecraft has 100 million players around the world. It has become one of the best-selling games of all time. Pupils can create their own virtual worlds with the help of special building blocks. Joy Morsi, a New York high school teacher, says that Minecraft helps develop the imagination of children in the classroom. Besides, teachers around the world create new things and share them with others, so that the Minecraft community keeps growing.

    Microsoft plans to make the game available to pupils and students of all ages, from primary school to college. The company plans to add Minecraft to an Office 365 account(账户), so that it can also sell more of its Office software.

    The US Department of Labour statistics (统计) show that there is an oversupply of college-trained workers and that this oversupply is increasing. Already there have been more than enough teachers, engineers, physicists, aerospace experts, and other specialists. Yet colleges and graduate schools continue every year to turn out highly trained people to compete for jobs that aren't there. The result is that graduates cannot enter the professions for which they were trained and must take temporary jobs which do not require a college degree.

    On the other hand, there is a great need for skilled workers of all sorts: carpenters, electricians, mechanics, plumbers, and TV repairmen.

    These people have more work than they can deal with, and their annual incomes are often higher than those of college graduates. The old gap that white-collar workers make a better living than blue-collar workers no longer holds true. The law of supply and demand now favours the skilled workmen.

    The reason for this situation is the traditional myth that college degree is a passport to a prosperous future. A large part of American society matches success in life equally with a college degree. Parents begin indoctrinating(灌输) their children with this myth before they are out of grade school. High school teachers play their part by acting as if high school education were a preparation for college rather than for life. Under this pressure the kids fall into line. Whether they want to go to college or not doesn't matter. Everybody should go to college, so of course they must go. And every year college enrollments (入学) go up and up, and more and more graduates are overeducated for the kinds of jobs available to them.

    One result of this emphasis on a college education is that many people go to college who do not belong there. Of the sixty per cent of high school graduates who enter college, half of them do not graduate with their class. Many of them drop out within the first year. Some struggle on for two or three years and then give up.

    In 1901, H. G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the "moon people" they met. In turn, the "moon people" expressed their surprise. "Why," they asked, "are you traveling to outer space when you don't even use your inner space?"

    H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the "moon people" asked is still an interesting one. A growing number of scientists are seriously thinking about it.

    Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The "Chunnel", a tunnel connecting England and France, is now complete.

    But what about underground cities? Japan's Taisei Corporation is designing a network of underground systems, called "Alice Cities". The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.

    Supporters of underground development say that building down rather than building up is a good way to use the earth's space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells' "moon people" would agree. Would you?

    Research suggests that at least 64% of people now spend up to four hours daily of spare time in front of a screen. Just as TV watching has been linked to higher chances of being fat and getting diseases, this extra sedentary (久坐不动) time is bad news for our health. .

And social networks have changed computer and mobile use for people of all ages.. Avoid aimless browsing (浏览) and give your time online a purpose: research holidays or catch up on the news of the day. Then log off.

    Last Friday when Jose Rodriguez, a 5-year-old white boy, asked his mother Lydia Rodriguez if he could get his blonde hair cut like his black friend Reddy's, and of course his mother agreed. For a very 1 reason the two pre-school friends decided to 2 their teacher with matching haircuts.

    Jose 3 that if he and Reddy had the same haircut, no one would be able to 4 them apart. Reddy apparently thought this trick was 5 as well.

    "It is just two 6 boys. Obviously, they see they are different colours, but they just don't care. It is not 7," Rodriguez said. She sees Jose's inability to see a 8 between himself and his friend as a parenting win. "I just taught him to 9 everyone the same," she said.

    The teacher played along and 10 she was talking to Jose when Reddy arrived before Jose and told the teacher and his 11he was Jose.

    On Monday, Rodriguez 12 the story on the Facebook.78,000 people 13 it and the story has gone viral(疯传). On the post she wrote: "If this isn't proof that 14 and prejudice is something that is 15, I don't know what is. Their 16 is the only difference Jose sees in the two of them. Though Jose loves 17 himself on TV and the Internet, he remains unsure why his haircut became such a big 18."

    He still has no idea why people 19 so much," Rodriguez said. "He wanted to 20 Reddy and now he thinks they look the same."
