Some people think the government should move the big companies and factories in cities to the countryside. To what extent do you agree?

    Due to the increased urbanization, there appears a bunch of heated social problems. Some people have noticed that there are many big companies and factories in the city and they believe that moving those big companies and factories into countryside could be a good way to solve many of the city problems, such as traffic issues and housing problems. However, I hold an opposite opinion to them and I will explain it as below.

    Cities have much more advantages than countryside. There are more cinemas, restaurants and shopping malls in cities, let alone better education and health care. Living in cities makes life more convenient and enjoyable. Thus not everyone is willing to move to countryside in spite of their companies' moving. They have got cars, which transfers them easily between work and home. Therefore, the pressure of traffic will not be released due to such solution. As for the available empty places spared by the big companies, the newest small companies will take good care of them—with the realization of the benefits that running a business in cities will bring to them. In other words, situation of housing will not be improved much.

    Besides, there will be more problems if big companies and factories move out. Where there are big companies and factories, there will be cities sooner or later. Consequently, countryside is to be disappearing. What's more, industrial pollution is not an easily mended problem.

    In conclusion, moving big companies and factories out of cities is never a final solution. It tackles(解决) no problem but causes lots of them. Just imagine. The traffic is still terrible, and there is no more scenic countryside. We should look into other ways to solve the problems.

You might think people all over the United States have Wi-Fi—-wireless Internet service—and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

    There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many American, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs—because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

    The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF)spends about ﹩8.2 million a year to operate the observatory, telescope and educational center.

    Jonah Bauserman is a technician. If he supposes there is a signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

    People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. “You know, instead of sitting here on our phones and other devices we're out fishing and hunting and going to each other's houses.” Everyone knows each other and communication is almost always face-to-face.

    Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are excessively concerned with their own appearance and actions.

    Worrisome thoughts are constantly occurring in their minds: what kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes? It is obvious that such uncomfortable feelings must negatively affect people. A person's conception of himself or herself is reflected in the way he or she behaves, and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a profound effect on all areas of their lives.

    Shy people, having low self-esteem, are likely to be passive and easily influenced by others. They need reassurance that they are doing "the right thing." Shy people are very sensitive to criticism; they feel it confirms their feelings of inferiority. They also find it difficult to be pleased by compliment with a statement like this one, "You're just saying that to make me feel good. I know it's not true." It is clear that while self-awareness is a healthy quality, overdoing it is harmful.

    Can shyness be completely eliminated, or at least reduced? Fortunately, people can overcome shyness with determined and patient efforts in building self-confidence. Since shyness goes hand in hand with a lack of self-esteem, it is important for people to accept their weaknesses as well as their strengths. Each one of us is a unique, worthwhile individual, interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our full potential. Let's not allow shyness to block our chances for a rich and fulfilling life.

A Chinese legend—A pretty maiden is trapped by a dragon. A prince must slay（杀死）the dragon to save her. Then, magically, they fall in love and live happily ever after. Traditional stories tend to emphasize the fantastic, magical side of love. Fate plays matchmaker. Strangers see each other from across a room and instantly know that they are destined to be together.

    It isn't difficult to imagine two strangers coming together and falling in love despite their differences. It suggests that love is challenging, uncertain, and incomprehensible.

    But with more people using online dating services, a very different kind of love has emerged: one that is scientific, convenient, and self-directed. It minimizes risk and provides a choice, like on a menu. There is anonymity（匿名）and the avoidance of immediate rejection. Meeting terms are negotiated online.

    Online dating also allows the setting of preconditions. Computer algorithms（推算） exclude undesirable traits such as the wrong hair color, race, or age. But they also exclude randomness. They reduce the chances of meeting someone different, or someone who could challenge one's romantic ideals. Instead, they find the partner we think we want and exclude everyone else. As a result, we could be missing the opportunity of a lifetime, to meet someone we would never have expected to fall in love with.

    Perhaps this new way represents a more efficient form of romance. Traditional ideas of love may be enchanting - but are they useful? Loneliness and boredom are less exciting than chance encounters, but they represent the more realistic side of love. All too often people have suffered through bad dates and humiliations. If they could just choose what they wanted, wouldn't it save time and reduce suffering? However, by choosing partners based on our preconceived ideas, we may be indulging in our illusions. Instead of letting ourselves grow with someone, love becomes more about looking for ourselves in the other. What if we don't know ourselves as well as we think? Perhaps love isn't about knowing what we want. Perhaps it's about being open to unimagined possibilities.

    The words “protect animals” appear everywhere in books and on screens because some animals are in danger of dying out. But sometimes the reality can be a little different from what people read or watch.

    Florida, US, has held its first bear hunt since 1994. The local government gave people nearly 4,000 permits to kill black bears. And more than 200 were killed on Oct 24.

    Animal protection groups protested this decision. But local officials explained that the black bear population had grown to 3,500 and become a menace to local people. In the past two years, bears have hurt at least four people in Florida.

    This brings an old question back into the spotlight – which is more important, protecting animals or protecting people's interests?

    This question is asked in other countries too. In Switzerland, a wolf was sentenced to death by the Swiss government months ago. This is because the wolf killed 38 sheep and local people lost a lot of money. Days ago in China, three old men were arrested for killing a serow(鬣羚), a protected species. But they insisted they didn't know about this and killed the animal because it ruined their crops.

    However, these stories don't always mean that animal protection stops due to human interests, especially involving economic development. A man named Zhou Weisen set up a wild animal base in Guilin, Guangxi. He saved over 170 tigers and 300 bears. But his base also offered jobs to local people.

    “There may never be a standard answer to the question of whether we should give more attention to the environment or human development,” said Robert May, a British biologist at Oxford University. “But we shouldn't push either one to the side, as the future is hanging in the balance.

Nick Torrance, a junior in high school, suffers from muscular dystrophy, and attends school in a specialized wheelchair. The muscle disease prevents him from accomplishing many everyday tasks, such as carrying his books and putting things away in his locker. So he had a fellow student assigned to help him. But Amy Smith, the school's occupational therapist, thought that being able to do something simple like opening his locker on his own would be empowering.

Amy initially thought they would be able to buy a device to help. But searching online turned up nothing that could meet their needs—everything needed a keycode or some other physical action, things her disabled student couldn't do. After the outside search for a method came up short, she looked within the school itself for an answer. Amy turned to the school's robotics instructor.

The instructor, in turn, suggested that two of his most capable students take on the project: Micah Stuhldreher and Wyatt Smrcka. They took first place in a national robotics competition, so they were a natural choice to tackle the locker door problem with a robotics solution. Micah and Wyatt wasted no time getting down to work and for an hour each school day, the boys brainstormed, built, and rebuilt various versions of the device until they landed on the perfect solution one year later.

Like in any device development, it took a lot of trial and error for Micah and Wyatt to make something that would work for their target audience. For example, they initially built a locker-opening button, but Nick wasn't strong enough to push it, so they replaced it with a sensor.

Now, between classes Nick steers his electric wheelchair to his locker and waves his hand over a sensor on the arm of the wheelchair. A few seconds later, the locker door swings open. Another wave closes the door. Nick can make it with ease—it may be a small thing, but it gives him a sense of independence.
