Why College Is Not Home

The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity. However, now they are becoming an extended period of adolescence, during which many of today's students and are not shouldered with adult responsibilities.

For previous generations, college was decisive break from parental control; guidance and support needed help from people of the same age and from within. In the past two decades, however, continued connection with and dependence on family, thanks to cellphones, email and social media, have increased significantly. Some parents go so far as to help with coursework. Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility, universities have given in to the idea that they should provide the same environment as that of the home.

            To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process involves “trying on ” new ways of thinking about oneself both intellectually(在思维方面) and personally. While we should provide “safe spaces” within colleges, we must also make it safe to express opinions and challenge majority views. Intellectual growth and flexibility are fostered on debate and questioning.

Learning to deal with the social world is equally important. Because a college community(群体) differs from the family, many students will struggle to find a sense of belonging. If students rely on administrators to regulate their social behavior and thinking pattern, they are not facing the challenge of finding an identity within a larger and complex community.

Moreover, the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults: the response to being controlled by their elders. If acceptable social behavior is too strictly defined(规定) and controlled, the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.

It is not surprising that young people are likely to burst out, particularly when there are reasons to do so. Our generation once joined hands and stood firm at times of national emergency. What is lacking today is the conflict between adolescent's desire for autonomy and their understanding of an unsafe world. Therefore, there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.

Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.

How to Care for Your Ears?

    Ears not only let us hear, but they also paly a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, except in a mirror. We take it for granted what they do for us day in and day out—until we notice something worng, such as when an earache strikes or when we start having to ask people to repeat what they say. {#blank#}1{#/blank#}

◆Clean your ear with a washcloth—covered finger only.

    Never put anything inside your ear canal, including cotton swabs (药签). {#blank#}2{#/blank#}

◆Leave earwax(耳垢) alone.

    Wax is your ear's way of eliminating （消除）anything foreign that gets into the ear canal. {#blank#}3{#/blank#} If you find you have too much earwax, use a few drops of earwax remover（去除剂）in the canal. After a few minutes, wash the ear with warm water.

◆Avoid noisy places.

    Rock concerts and construction sites are just a few places that frequently have noise levels that can damage

hearing.Any place where you have to shout to be heard should be avoided.

◆{#blank#}4{#/blank#}

    Be careful not to play MP3 too loud, especially if using earphone.

◆Be careful with illness and medications.

    Respiratory illnesses should be treated to avoid their spread to the ears. Certain medications can damage hearing, so follow the directions carefully before taking them.

    See your doctor if you suffer from sudden hearing loss or hear noises in your head. {#blank#}5{#/blank#}

A．Most people don't need to clean wax out of their ears.

B．In such case, go to see a doctor as soon as possible.

C．These can be symptoms of a serious illness which needs to be treated.

D．This article will show you how to care for your ears.

E．Turn the volume down.

F．Avoid using earphones while listening to MP3.

G．Your ear canal is very narrow, and a swab can damage it.

    Recently a new study has been carried out. It shows students who write notes by hand during lectures perform better on exams than those who use laptops.

    Students are increasingly using laptops for note-taking because of speed and legibility (清晰度). But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment, students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said, “While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”

    In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.

    Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星) which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

    However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.

    Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.

    This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

    It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested.

    In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley's comet, in his honour.

    Safe Travel Abroad

    Preparing to go traveling abroad can be really stressful （有压力的）, especially if you don't know what to expect. Here is a list of important things to remember, so you know exactly what you need to do before you take off.

    What vaccines(疫苗) do I need?

    Go to your doctor for advice as soon as you know you're going traveling. They will know what vaccines you will need and will be able to advise you on when you need to have them. Remember, some vaccines need to be given months ahead, so make sure you book an appointment as early as possible.

    Do I need a visa(签证)?

    It's important that you have the correct official documents for traveling abroad. If you don't have the necessary paperwork, you might be refused entry. You'll need to check that your passport hasn't been out of date either.

    How do I arrange travel insurance(保险)?

    Travel insurance is really important. It can protect you in different kinds of situations, such as if you need medical treatment or if your flights are canceled. Travel insurance can be arranged easily online or over the phone, but you can always turn to your local travel agency. Travel agents will also be able to advise you on what you are insured against.

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 Americans, 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 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.
