Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feeling can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm, reasonable way. Others burst with anger, losing control of themselves. But still other people control their anger. They cannot or will not express it.

    For years many doctors thought that controlling one's anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain lets out the same hormones that are produced during tense situations. They speed the heart rate, raise blood pressure, and narrow the blood vessels. In general, the person feels excited and ready to act.

    Doctors said that controlling these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger too often and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.

    Some doctors say that both controlling and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

    “I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that's a conservative estimate (保守的估计).”

    At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”

    However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

    Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”

    It was an oral English class and in front of us was standing our teacher Lila Betray, who was a university student from the US. Somehow we came to the point whether any of us could sing an English pop song in front of the class. You know, maybe three or more out of ten Chinese students are shy in class. As a result, there was silence in class for quite a while, which made everybody feel rather embarrassed (尴尬的), including the teacher.

    I was a shy boy. However, just at that moment, a great idea struck me suddenly. “Seize the enjoyment! Seize the chance. Yes, there couldn't be a better chance.” I said to myself. “Why not seize it? Why should I have always to be the guy regretting missing the opportunity just because of shyness? Yes, maybe I should have a try!”

    So, I raised my hand. And I remember that it took me quite a while to think what the song's name was. Though I sang no more than five sentences because of forgetting the lyrics (歌词), their clapping hands told me that I did the job well. Later, I got a gift and I was really happy.

    I think that is one of the most unforgettable moments in my life. Through this experience, I've also got to know that we should believe that we can do the job well, no matter how difficult it seems for us. Just have a little more courage.

    If you read and listen to one article every day, your reading and listening skills can improve fast. You can learn quickly and after some time you will not have to translate it into your own language. You will simply understand. Why should you do this?

    When you listen to your native language, you do not translate. You simply understand. The same has to be in English. When you learn English, you have to learn the whole sentences in the context (语境).

    Students, who translate English texts, do exercises and do tests, are very good at translating, doing exercises and doing tests, but they have problems with understanding English in real life. In real life, nobody waits for your translation. People usually use simple English when they speak but they speak it fast. You have to understand with no translation into your native language. If you translate, you cannot be part of communication because you are thinking about the language too much.

    You also have to hear every new word 5 to 10 times if you want to remember it. That's why we use the same words at one level. If you read and hear the same words again and again, you will understand them and remember them. If you know words from one level perfectly well, you can go to a higher level and learn new words. It is important to go step by step, and read and listen to words which are used in English often.

    We are trying to do everything possible to help you learn English fast and understand it. That's why we prepare easy English news for you. If you can use this website every day, you can learn 5,000 words which you need for communication with anybody. Now click the OK button to start.

    Once an Englishman named Jack Brown went to Russia for a holiday. He stayed there for several months and then came home again. Some of his friends visited him a few days after he got back. "I had a very dangerous trip while I was in Russia," Jack said to them. "I wanted to see a friend of mine in the country and the bad weather made me very late. So I was still traveling through a forest in a sleigh(雪橇) when the sun went down. It was a long way from my friend's house when about twenty wolves began to follow my sleigh. It was very dark in the forest. There was thick snow on the ground. It was cold, and there were no houses for miles and miles. First I heard the wolves. The noise was terrible! The horses heard them, too. They were frightened and began running faster. Then I saw long, gray forms among the trees, and soon the wolves were near us. They were running very fast, and they didn't seem to get tired like the horses."

    "What did you do?" one of Jack's friends asked.

    "When the wolves got very near," Jack answered, "I put up my gun and shot the first wolf. The sleigh was moving about, but I hit the animal and killed it. Then all the other wolves stopped and ate it, so our sleigh got away from them for a few minutes."

    "Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another of them, and the others stopped once more to eat it."

    "The same thing happened again and again, and my horses became more and more tired and ran slower and slower until, after about two hours, only one wolf was still alive and following us."

    "Wasn't it too fat to run?" one of his friends asked.

    "IF ALIENS are so likely, why have we never seen any？" That is the Fermi Paradox（悖论） named after Enrico Fermi, a physicist who posed it in 1950.

    Fermi's argument ran as follows. The laws of nature supported the appearance of intelligent life on Earth. Those laws are the same throughout the universe. The universe contains zillions of stars and planets. So, even if life is unlikely to arise on any particular astronomical body, the sheer abundance of creation suggests the night sky should be full of alien civilizations. Fermi wondered why aliens had never visited the earth. Today, the paradox is more usually cast in light of the inability of radio﹣telescope searches to detect the equivalent（相等的） of the radio waves that leak from Earth into the universe, and have done for the past century.

    Thinking up answers to this apparent contradiction has become something of a scientific parlour（客厅）game. Perhaps life is really very unlikely. Perhaps the priests are right: human beings were put on Earth by some creator God for His own unknown purposes, and the rest of the universe is merely background scenery. Perhaps there are plenty of aliens, but they have decided that discretion is a safer bet than gathering together. Or perhaps galactic（银河的） society avoids communicating with Earth specifically. One frightening idea is that technological civilizations destroy themselves before they can make their presence known. They might blow themselves up after inventing nuclear weapons （an invention that, on Earth, Fermi had been part of）, or cook themselves to death by over﹣burning fossil fuels.

    In a paper published last month on arXiv, an online repository（文献库） , a group of three astronomers at Pennsylvania State University have analyzed the history of alien hunting and come to a different conclusion. In effect, they reject one of the paradox's main theory. Astronomers have seen no sign of aliens, argue Jason Wright and his colleagues, because they have not been looking hard enough.
