As a new driver with little experience behind the wheel, having to turn into another lane（车道）to avoid a careless driver talking on a cellphone is not something that I am prepared for. According to the New England Journal of Medicine, an accident is four times more likely to happen than normal while you are talking on the phone. Therefore, I hold the view that using a cellphone while driving should be outlawed（宣布……不合法）.

    Cars are two-ton weapons and should be treated as such. When drivers put a key in the engine, they are taking on the responsibility of being a driver. Answer the phone while driving is like taking the safety off a gun ― at any moment something could go wrong and change a life forever.

    A few countries, including Australia, Great Britain, Spain and Israel, have recognized the damage that cellphone use can cause. According to Tom Alex of The Des Moines Register, people who talk on cellphones while driving are just like drunk drivers. They are likely to make a deadly mistake, causing them to hurt themselves or someone else.

    Some may think that cellphone are helpful when you need directions or are in an emergency situation. Although I agree, I believe the safest way to use your phone is to pull over to the side of the road first. Some may think that hands-free phones are less dangerous, but studies have shown that the danger remains the same with these.

    Using a cellphone while driving should be outlawed. One small mistake could change your whole life. Please don't let that happen ― stay off your cellphone while driving.

    By now, we are all aware that social media has had a powerful influence on our culture, in business, on the world at large. Social media websites revolutionized the way people communicate and socialize on the Web. However, besides seeing your friends' new baby on Facebook, or reading about Justin Bieber's latest conflict with the law on Twitter, what are some of the real influences?

    Social networks offer the opportunity for people to reconnect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and take part in campaigns and activities of their choice. Professionals use social media sites like Linkedln to improve their career and business development. Students can work together with their peers to improve their academic and communication skills.

    Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying(网络欺凌) and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

    Many companies have blocked social networks as addicted employees can distract (分心)themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

    Also, what you carelessly post on the Net can come back to trouble you. Leaking personal information on social sites can make users easily harmed to crimes like identity theft, stalking(尾随犯罪), etc. Many companies perform a background check on the Web before hiring an employee.  If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

    Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to improve their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

    The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

    Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.

    The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.

    Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang(团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.

    Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of. And it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.

    Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.

    Unemployment in the United States is still high at 6.7％. But for job seekers, especially those with college educations, researchers say finding a job can be as easy as logging(登录)on to a computer. It used to be that looking for a job meant hurrying around, knocking on doors and turning to ads. But that's changing, thanks to the Internet. A new report says, for college graduates, looking for a job is getting easier. More than 80 percent of the jobs are available online.

    At the height of the depression(萧条), in the U. S. the highest unemployment rate was 10％, just a little more than two million jobs were being posted each month. But as the recovery takes hold, the job picture looks increasingly bright.

    That's great news for Hamilton. Only once has he ever applied in person for a job at a shopping mall. He said, "I think my generation—the idea of going door to door, out knocking and saying, hey are you hiring? —like that—doesn't exist anymore…those days are gone. Just go online.''

Kim Dancy recently graduated with a master's degree in Public Policy. She found her dream job as an education policy researcher. But she says finding the perfect job online takes a lot of perseverance. She said, "It can be really frustrating and it takes a long time, but if you applied for enough positions and really do your homework you will get somewhere.

    The report's findings suggest careers in Science, Technology, Engineering and Math provide the greatest opportunities, with salaries that range between $30 to $45 an hour. But for maximum income and satisfaction, workers must be prepared to move and change jobs at least every five years.

Daphne Soares, a biologist, makes an amazing discovery about alligators. The first time she got really close to an alligator (短吻鳄) was when she was helping to bold down an eight-foot American alligator. It was then that she noticed is face was covered with little black spots. This led to the discovery of the little black dots.

She started her study of the black dots. When she read the books and scientific journals, she learned that people had noticed the dots, but no one really knew what the dots were for.

To find out the secret she placed electrodes (电极) on nerves coming from some of the dots. When the nerves fired, they sent a message to the brain and created a tiny electric current. Just then she heard a small sound over a loudspeaker. She tired to see if the dots acted like eyes and temperature sensors, but nothing worked.

One day she was careless with dropping a tool into an alligator's tank. When she put her hand in the tank to get the tool out, she made small waves in the water. When they reached the alligator's face, she heard a noise over the speaker. She then realized that the dots must be sensitive to the changes in pressure when hit by waves of water.

After that, she is now studying blind cavefish. She is trying to learn whether they are blind from birth or lose their sight as they grow up. She is also doing more research on crocodilians (鳄目). She wants to find out how the genes of alligators with pressure sensors only on their faces differ from the genes of crocodilians that have pressure sensors all over their body.
