Body language is an important part of communication(交流). If you want to communicate well, it's important to understand how you can (and can't) use your body to say what you mean, especially when you're in a foreign country. If a person is bored, he won't look at the person who is talking to him. He will find other things to do. He may also keep looking at his watch or a clock. If a person is open to you, his arms and legs will not be crossed. And if a person is relaxed, you will know it by looking at his body, even his breathing is slower.

Here are some examples of body language:

    We all know that listening to music can soothe emotional pain, but Taylor Swift, Jay-Z and Alicia Keys can also ease physical pain, according to a study of children and teenagers who had major surgery.

    The research was carried out because of a very personal experience. Sunitha Suresh was a college student when her grandmother had major surgery and was put in intensive care (重症监护). This meant her family couldn't always be with her. They decided to put her favorite music on an iPod so she could listen around the clock.

    It was very calming, Suresh says. “She knew that someone who loved her had left that music for her and she was in a familiar place.”

    Suresh could see that the music relaxed her grandmother and made her feel less anxious, but she wondered if she also felt less pain. That would make sense, because anxiety can make people more sensitive to pain. At the time Suresh was majoring in biomedical engineering with a minor (兼修) in music cognition (认知) at Northwestern University where her father, Santhanam Suresh, is a professor of pediatrics (儿科).

    So the father and daughter decided to do a study. And since Dr Suresh works with children, they decided to look at how music chosen by the children themselves might affect their tolerance for pain.

    It was a small study, involving 60 patients between 9 and 14 years old. All the patients were undergoing big operations that required them to stay in the hospital for at least a couple of days. Right after surgery, patients received narcotics (麻醉药) to control pain. The next day they were divided into three groups. One group heard 30 minutes of music of their choice, one heard 30 minutes of stories of their choice and one listened to 30 minutes of silence via noise canceling headphones.

    After a 30-minute session, the children who listened to music or books reduced their pain burden by 1 point on a 10-point scale. Sunitha Suresh says it's equal to taking an over-the-counter pain medication like Advil or Tylenol.

    The findings suggest that doctors may be able to use less pain medication for their pediatric patients. And that's a good thing, says Santhanam Suresh, as children are smaller and are more likely to suffer side effects. So the less pain medication, he says, the better.

    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.

    A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian's National Zoo in Washington, D.C. But unlike the zoo's other residents, they are not real animals. These creatures are actually huge sculptures and they're made entirely out of plastic trash from the ocean.

    These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in Earth's oceans.

    More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches, rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.

    Thousands of marine animals--including whales, sea turtles, and fish--die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.

    Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.

    The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.

    “These sculptures are a powerful reminder of our personal role and global responsibility in preserving biodiversity(生物多样性) on land and in the sea,” says Dennis Kelly, director of the National Zoo.

    There was great excitement on the planet of Venus (金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs.

    The satellite was directed into an area known as Manhattan (曼哈顿). Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information about the feasibility of a manned flying saucer (飞碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week's satellite landing,” Professor Zog said, “that there is no life on Earth."

    “How do you know this?” the science reporter of the Venus Evening News asked.

    "For one thing, Earth's surface in the area of Manhattan consists of solid concrete (混泥土) and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”

    “Are there any other sources of danger that you have discovered in your studies?”

    “Take a look at this photo. You see this dark black cloud staying over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there. Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink.”

    “Sir, what are all those tiny black spots on the photographs?”

    “We're not certain. They seem to be metal objects that moves along certain roads. They give out gases, make noise and keep crashing into each other.”

    “Professor Zog, why are we spending billions and billions of Zilches to land a flying saucer on Earth when there is no life there?”

    “Because if we Venusians can learn to breathe in the Earth atmosphere, then we can live anywhere.”

    It was New Year's Night. An aged man was standing at a window. He raised his mournful (悲哀的) eyes towards the deep blue sky, where the stars were floating like white lilies (百合花) on the surface of a clear calm lake. He had already passed sixty and brought from his journey nothing but errors (错误) and regrets. Now his health was poor, his mind vacant and his heart sorrowful (悲伤的).

    The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads—one leading to a peaceful, sunny place, covered with flowers, fruits and filled with soft, sweet songs; the other leading to a deep, dark cave, which was endless, where poison flowed instead of water and devils and poisonous snake hissed (发撕嘶声) and crawled (爬行).

    He saw the lights flowing away in the darkness. These were the days of his wasted life; he saw a star fall from the sky and disappeared, and this was the symbol (象征) of himself. His regret like a sharp arrow (箭) struck deeply into his heart. Then he remembered his friends in his childhood. But they had made their way to success and were now honoured and happy on this night.

    The high church clock struck and the sound made him remember his parents' early love for him. They had taught him and prayed for his good. But he chose the wrong way. With shame and grief he dared no longer look towards that heaven. His darkened eyes were full of tears, and with a despairing (绝望的) effort, he burst out a cry: "Come back, my early days!"

    His youth did return, for all this was only a dream which he had on New Year Night. He was still young though his faults were real; he had not yet entered the deep, dark cave, and he was still free to walk on the road which leads to the peaceful and sunny land.

    Those who still wander (徘徊) on the entrance of life, hesitating (犹豫) to choose the bright road, remember that when years are passed and your feet stumble (绊脚) on the dark mountains, you will cry bitterly, but in vain (徒劳): "Oh youth, return! Oh give me back my early days!"
