    About 45 percent of Americans don’t get enough sleep, according to a recent survey. However, the benefits of getting enough sleep far outweigh the thrill of watching TV for one more hour or surfing the web. Getting a better night’s sleep will help you lose or keep your weight more effectively. Try these simple steps to improve your quality of sleep.
    Take time to relax
    So many of us go-go-go until it’s time for bed, but it’s important to take time to slow down and relax before sleeping. Do relaxing things, such as listening to soothing (抚慰的) music or deep breathing. Avoid stimulating (刺激的) activities such as writing e-mails, talking on the phone and watching TV. Some guidelines (指导方针): no e-mail after 8 p.m. and no TV or phone calls after 9 p.m..
    Darker is better
    Your body regulates your sleep cycle in response to the presence and absence of light, so dim the lights as evening approaches. Try getting ready for bed by candlelight. When you’re ready to sleep, make sure your room is as dark as possible.
    Put your thoughts to bed
    We all need time to process our day, but bed is not the place to do it if you want to sleep well. Take 10 to 15 minutes to record your thoughts in a journal. This effective technique will capture what’s in your mind so you don’t lie awake. Tell yourself you’re putting your thoughts to bed so that you can go to bed.
    No sugar or alcohol before bed
    These may wake you up. If you need a snack before bed, make it protein.
    Try to get more sleep
    Get an extra hour or two of sleep every night for a week and see how you feel. You’ll notice the difference!

    Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships do not last very long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend treat you. Learning to be a good friend means learning three rules. Be honest; be generous; be understanding.
    Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest you may lose your friends’ trust. Good friends always count on one another to speak and act honestly.
    Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money on your clothes of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interest. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.
    Sooner or later every one needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
    No two friendships are ever exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practise honesty, generosity, and understanding.

    A．there are too many people who want to make friends.
    B．those who never give others friendships receive no friendship from others.

    Scientists warn today that the Atlantic bluefin tuna（金枪鱼）faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined.
    The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as £ 52,000 in the Tokyo fish markets. “In my lifetime, we’ve brought this big fish to the doorstep of death in the western Atlantic Ocean,” said Barbara Block of Stanford University in California. “The electronic way of tracks provides the best scientific information we’ve ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. ”
    Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna—in the Mediterranean and Japan—have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969．There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked.
    So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. “There are two ways to save the Atlantic bluefin tuna—protect them in their production grounds and in their feeding grounds,” Prof. Block said. “This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. ”
    小题1: The bluefin tuna in this passage mainly refers to the one _______.
    A．in the AtlanticB．in the Pacific
    C．in the Gulf of MexicoD．in the Mediterranean
    小题2:Which of the following is NOT true according to this passage?
    A．The bluefin tuna is a kind of large and heavy fish.
    B．The number of the bluefin tuna in the sea is getting smaller and smaller.
    C．Scientists are worried about the future of the tuna.
    D．Scientists think that the harvest of the seas will remain good.
    小题3:According to Professor Block, tuna can be saved by ______.
    A．finding a new way to protect them
    B．controlling the catches of them
    C．reducing the population to eat them
    D．protecting them in their production and feeding grounds
    小题4:The purpose of the passage is to ______.
    A．tell people a new way has been found to save the bluefin tuna
    B．call for action to save the bluefin tuna
    C．warn people not to eat tuna sandwiches anymore
    D．help scientists to find a new way to save the bluefin tuna

    There are hundreds of things that your parents controlled for you when you were a child．And it’s a good thing, too — kids need this kind of protection and assistance, because they aren’t mature enough to take care of themselves and make careful decisions on their own．
    But eventually, kids grow up and become teens．It’s totally normal for teens to create their own opinions, thoughts, and values about life; it’s what prepares them for adulthood．But as you change and grow into this new person who makes his or her own decisions, your parents may have a difficult time adjusting themselves to it．
    In most families, it’s this adjustment that can cause a lot of fighting between teens and parents．Teens get angry because they feel parents don’t respect them and aren’t giving them space to do what they like, and parents get angry because they aren’t used to not being in control or they disagree with the teens’ decisions．
    It’s easy for feelings to get very hurt when there are conflicts like these．And more complicated issues can cause even bigger arguments, because your parents will always be intent on protecting you and keeping you safe, no matter how old you are．
    The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teens have a right to certain opinions．It can take several years for parents and teens to adjust to their new roles, though．In the meantime, concentrate on communicating with your parents as best you can．
    Sometimes this can feel impossible — like they just don’t see your point of view and never will．But talking and expressing your opinions can help you gain more respect from your parents, and you may be able to reach a compromise that makes everyone happy．Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through．
    小题1:Why do parents always want to control their children?
    A．They are afraid to lose their children．
    B．They want to protect their children．
    C．They don’t believe the ability of their children．
    D．They can’t accept their children are growing．
    小题2:The author suggested that teenagers ________．
    A．fight with their parents bravely for their rights
    B．obey their parents without any doubt
    C．communicate with their parents actively
    D．persuade their parents in as many ways as possible
    小题3:It can be inferred from the passage that ________．
    A．most parents will give in while fighting with their children
    B．the conflict between parents and teenagers can be solved
    C．the only way for teens to get freedom is to leave home
    D．only few parents do well in facing the growth of their children

    Boris Worm of Dalhousie University in Nova Scotia, Canada, led the international team that did the study. Professor Worm says species have recently been disappearing from oceans at increasing speed. At this rate, he says, all seafood species could collapse by 2048 and seafood supplies from the world’s ocean could be almost gone by then.
    Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty in fifty years. Some scientists said parts of the world do have problems, but others are doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
    The study appeared earlier this month in Science magazine.
    The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appeared to increase the risk of fish kills and beach closures from harmful algae growth.
    The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization for nineteen fifty to two thousand three. And they examined archeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
    Boris Worm says the findings were, in his words, "beyond anything we suspected." But he also said the situation is not too late to correct. He said that with good fisheries management, some species could completely recover in three to ten years.
    小题1:Which of the following isn’t the damage to the ocean?     
    A．The species of fish in the ocean are reducing.
    B．Sea water is polluted.
    C．Sea water quality is improved.
    D．Less productivity of ecosystem.
    小题2:The conclusion of the research led by Boris Worm is _________. 
    A．unbearableB．unbelievable
    C．doubtfulD．Convincing
    小题3:The research led by Boris Worm _________.          
    A．was conducted by scientists from Canada
    B．referred to information of many countries
    C．lasted from 1950 to 2003
    D．referred to records dating back to over 1,000 years ago.
    小题4:Which of the following statements is NOT true?      
    A．It’s too late to take action to improve the situation.
    B．Some species will recover with efforts.
    C．Boris Worm hopes that people take the warning serious.
    D．Boris Worm shows great concern about ecosystem.

    As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治疗的) stem cells.
    In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
    Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
    小题1:The best title of this passage probably is _______.
    A．The importance of clone
    B．First insects are cloned
    C．The disagreement in clone
    D．The advantages of clone
    小题2:The scientists cloned flies because________.
    A．there are fewer and fewer flies in the world
    B．flies are easy to find and cheap to use
    C．they can gain some experience before cloning other animals
    D．it is safe to clone flies
    小题3:The failure of most cloned animals is due to _______.
    A．the difference of other animals’ genes
    B．the improper technique of clone
    C．the complex of other animals
    D．the improper rearrange of the adult gene
    小题4:It can be inferred from the last paragraph that ______.
    A．the clone of insects before used grown-up cells
    B．the clone of insects were never experimented before
    C．this time scientists cloned flies successfully and easily
    D．based on this success, other animals will be cloned in large quantities.

    “My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills and more.
    The children don’t just plan any city. They map and analyze (分析) the housing, energy, and transportation requirements of their own district and foretell its needs in 100 years. With the aid of an architect (建筑师) who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing buildings of the future gives children a lot of freedom,’’ says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected ‘official’ and ‘planning group’ make all the design decisions for the model city and the teacher steps back and becomes an adviser.
    CBEP is a set of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children’s own standards.
    小题1:The program is designed to_________.
    A．direct kids to build solar collectors
    B．train young scientists for city planning
    C．develop children’s problem-solving abilities
    D．help young architects know more about designing.
    小题2:An architect pays a weekly visit to the classroom to ________.
    A．find out kids’ creative ideasB． help kids with their program
    C． discuss with the teacherD． give children a lecture
    小题3:Who is the designer of the program?
    A．An official.B．An architect.C．A teacher.D．A scientist
    小题4:The children feel free in the program because __________.
    A．they can design future buildings themselves
    B．they have new ideas and rich imagination
    C．they are given enough time to design models
    D．they need not worry about making mistakes

    With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills（泄露） on people, nature, and the environment．
    Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．
    Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．There are, of course, long-term effects, but it is usually more serious in the short term．
    Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible．In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．
    Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
    We should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太阳能）, electricity, hydrogen, and so on．Much of this research has, in the past, been held back by the oil, gas, and coal．
    If the world’s millions of cars were 10% more efficient（高效的）— and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．
    小题1:What is the passage mainly talking about?
    A．Oil tanker accidents．B．Oil spills pollution．
    C．What oil pollution is．D．How to reduce oil pollution．
    小题2:How does the author support the idea that oil spills are not as serious as people believe?
    A．By giving a description．B．By making an argument．
    C．By giving an example．D．By drawing a diagram．
    小题3:What does the underlined word “risk” in Paragraph 5 refer to?
    A．Transportation depending more on oil．
    B．Poisonous oil breaking down naturally．
    C．Millions of tons of oil spilling into the sea．
    D．More environmental damage being caused．
    小题4:Which suggestion is made for reducing oil tank accidents according to the passage?
    A．We should develop new technologies to cut oil use
    B．Tankers should not be allowed to sail near the coastlines．
    C．We should build safer oil tankers in the near future．
    D．Countries should build more oil pipelines under the sea．
