    Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly.
    You probably know how to ride a bike safely. Now learn to use a computer safely.
    Your eyes--Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
    When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect (反射) on the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
    Your hands--Hand injuries can happen because the hands are moved in the same way hundreds of times. If you use a keyboard for a long time, follow this rule: Stop sometimes and exercise your hands and fingers in different ways.
    Your back--Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back and your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.
    Enjoy your computer, but use it safely.

    Remembering names is an important social skill．Here are some ways to master it．
    Recite and repeat in conversation．
    When you hear a person’s name，repeat it．Immediately say it to yourself several times without moving your lips．You could also repeat the name in a way that does not sound forced or artificial．
    Ask the other person to recite and repeat．
    You can let other people help you remember their names．After you’ve been introduced to someone，ask that person to spell the name and pronounce it correctly for you．Most people will be pleased by the effort you’re making to learn their names．
    Admit you don’t know．
    Admitting that you can’t remember someone’s name can actually make people relaxed．Most of them will feel sympathy if you say．“I’m working to remember names better．Yours is right on the tip of my tongue．What is it again?”
    Use associations．
    Link each person yon meet with one thing you find interesting or unusual．For example，you could make a mental note: "Vicki Cheng -- tall, black hair. " To reinforce (加强) your associations, write them on a small card as soon as possible.
    Limit the number of new names you learn at one time.
    When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
    Go early.
    Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That's fewer names for you to remember. And as more people arrive, you can hear them being introduced to others -- an automatic review for you.
    小题1:How will most people feel when you try hard to remember their names? 
    A．They will be moved.B．They will be annoyed.

    C．How to make use of associations.D．How to recite and repeat names.

    A twisted sense of humor and a strong voice cast（演出人员） make "Open Season" fun for kids and adults. It's a great start for Sony's animation studio.
    Boog is a full-grown grizzly（灰熊）bear that has been raised among humans by park ranger Beth. He has a warm place to live, all the food he wants, and is safe from hunters.
    However, when he crosses paths with the spastic(大脑性麻痹的) mule deer Elliot, all that changes. Thanks to a series of misunderstandings, everyone believes Boog is dangerous and out of control. Beth is forced to release(释放) him back into the wild.
    Once Boog finds himself in the great outdoors, he has no idea what to do. He gets lost, can't find food, and is attacked by unfriendly forest cutters. Boog is forced to rely on the idiotic Elliot to help him find his way back to civilization(文明). But can they make it before open season begins for hunting?
    The movie also has a really strong voice cast. Martin Lawrence voices Boog, and his attitude and persona（人格面具）perfectly fit the bear. The same goes for Aston Kutcher as Elliot. Even if you can't stand him in the real world, you'll be surprised how well he brings the annoying deer to life in the movie.
    The animation in "Open Season" is also excellent. The characters are quite cartoonish, but the hair is realistic looking and the movements are fantastic. The body language adds a lot to the performances of the characters.
    小题1:What’s the key factor(因素) that the Boog need to survive himself in the wild?
    A．He wants to seek a comfortable settlement.
    B．It’s thought that the Boog is beyond control.

    Comera is the only place in the world which has a whistle(口哨)language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley cannot easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
    We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of the telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
    The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera island you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.
    小题1:If a person on Comera island is ill, 　　　.
    A．others will phone the doctor in town
    B．the whistle language will pass the news to the doctor
    C．his family will take him to the doctor
    D．people will take him to the hospital
    小题2: From the passage we know radio and TV　　　at that time.
    A．killed the special ways of speaking
    B．whistled all the news and opinions
    C．helped Comera people to communicate
    D．did not appear on Comera island yet
    小题3: Comera island is special in that　　　.
    A．it attracts visitors every year
    B．no visitors have ever been there
    C．people there have special ears to hear whistles
    D．people there use the whistle language to communicate with each other
    小题4: Which of the following is NOT true according to the passage?
    A．It is not easy for a person to live on Comera island if he cannot whistle.
    B．The whistle language can only be found on Comera island.
    C．The whistle language has been used for hundreds of years on the island, but will not be used any longer.
    D．The record shows that one best whistler can be heard by others seven miles away.

    When I entered Berkeley, I hoped to earn a scholarship. Having been a Straight-A student, I believed I could       tough subjects and really learn something. One such course was World Literature given by Professor Jayne. I was extremely interested in the ideas he       in class.

I’ve always remembered Professor Jayne’s lesson: you alone must set your own standard of excellence.

    When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
    It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
    Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.
    小题1:It can be inferred from the passage that the author’s opinion of nowadays’ human beings is
    A．not very high. B．high.
    C．contemptuous. D．critical.
    小题2:The main idea of this passage is
    A．vicious and dangerous sports should be banned by law.
    B．people are willing to pay vast sums money to see violence.
    C．to compare two different attitudes towards dangerous sports.
    D．people are bloodthirsty in sports.
    小题3:That the author mentions the old Romans is
    A．To compare the old Romans with today’s people.
    B．to give an example.
    C．to show human beings in the past know nothing better.
    D．to indicate human beings are used to bloodthirsty.
    小题4:.How many dangerous sports does the author mention in this passage?
    A．Three. B．Five.
    C．Six. D．Seven.
    小题5:The purpose of the author in writing this passage is
    A．that, by banning the violent sports, we human beings can improve our selves.
    B．that, by banning the dangerous sports, we can improve the law.
    C．that we must take positive steps to improve social welfare system.
    D．to show law is the main instrument of social change.

    Are you stressed out, scared or worried all the time? Do you avoid going to certain places, seeing friends or doing certain things because of your worries? Do your worries keep you awake at night? If you’ve answered yes, you may be suffering from anxiety.
    Anxiety is a normal and necessary part of life. Anxiety is your brain’s way of telling you about danger. It is anxiety which helps you jump out of the way if a car is speeding towards you. But if it gets out of hand, anxiety can get in the way of your getting on with life and can become a real problem. If this is the case for you, treatment may be a helpful way for you to get your anxiety under control.
    Anxiety is a normal part of life. Some people may feel uneasy if moving to a new place and some may get overly anxious in certain situations. There are lots of reasons for this. One main reason is after a stressful thing which has happened in your life. So, if you are involved in a car crash, it’s quite likely that you will be more worried than other people around cars and driving.
    Being anxious also probably runs in families. If your parents suffer from anxiety then you are more likely to be anxious too. This is probably partly due to genetics, and partly because of how things are when you’re growing up.
    Even though people don’t talk about it much, anxiety is one of the most common mental health problems. About 1 in 4 people will have an anxiety problem at some time in their life.
    If you have an anxiety problem it’s hard for other people to understand why something that doesn’t worry them, like being in a crowd of people, can be so scary for you. This can make you feel separated and lonely, as may become worse and worse.
    The good news is there are lots of excellent treatments available for anxiety. These include taking therapies (疗法) and drugs.
    小题1:Which of the following statements is true about anxiety?
    A．With anxiety you are far away from traffic accidents.
    B．It’s abnormal for people to get too anxious after a stressful thing.
    C．Almost everybody has a certain degree of anxiety in certain situations.
    D．When you feel stressed out, scared or worried, you are surely suffering from anxiety.
    小题2: Which of the following reasons for anxiety is NOT mentioned in the passage?
    A．Illness.B．Experience.C．Genetics.D．Environment.
    小题3: What can we infer from the fifth and sixth paragraph in the passage?
    A．Anxiety is the most common mental health problem.
    B．Those suffering from anxiety need others’ understanding badly.
    C．About a quarter of the population are suffering from anxiety now.
    D．Once you suffer from anxiety, you’d better seek for medical treatment.
    小题4:The author will most probably talk about ________ following this passage.
    A．what is about anxietyB．what causes anxiety
    C．how to handle anxietyD．when anxiety becomes serious

    People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume(消费) is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think."
    In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity(肥胖), a 25% increase in the risk for abnormal(非正常的) blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol(胆固醇).
    All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It’s something that surprised even the researchers.
    Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that."
    In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.
