    Besides calling 911, here is what to do in some life-threatening emergencies when no oneis

             

     
    around to help.

    Lost in the wilderness
    First, you’ve got to acknowledge you’re in trouble. Stay where
    you can be seen clearly and remember to rest. Keeping a sense
    of humor helps too—it reduces stress and helps creative thinking.
    In a wide open area, make a colorful cross out of rocks to show
    your present position.

     

     
    Choking

    Aim to hit the top of the chair against your stomach, in the soft part
    below the bony upside-down V of the ribs（肋骨）. Make a sudden
    push against the chair. If you still can’t breathe after six tries, call 911,
    even if you can’t talk. Write the word choking somewhere nearby, and
    leave the line open until help arrives.


     
    Severe bleeding

    Use your hand or clean cotton, or paper towels, or a scarf,
    or any cloth you can find, and push down on the wound
    until the bleeding stops. But if you put a band around
    your leg tightly, you’re going to close the vessels（血管）
    to the entire leg. In this way, you could lose your foot.
    Bear attack


     
    If you surprise a bear, don’t run away. That invites an attack.

    Instead, stand up and back away slowly, without looking the
    bear in the eyes. If it does charge at you, stick out your chest,
    raise your arms, and spread your legs. Shout at the bear, to
    frighten it. If it’s going to attack, lie facedown, with your hands
    held firmly behind your neck. Play dead until you’re sure the bear
    is gone.
    小题1:When you see a colorful cross made of rocks in the wilderness, you know    .
    A．someone is bleedingB．someone is choking
    C．someone is lostD．someone is attacked by a bear
    小题2:If you are still choking after six tries, you should         .
    A．keep a sense of humorB．call 911 and leave the line open
    C．use your hand our clean cottonD．lie down with your hands behind your neck
    小题3:Don’t tie around your bleeding leg tightly, or you could        .
    A．stop bleedingB．reduce stress
    C．lose your footD．cause breathlessness
    小题4:The passage is mainly teaching us how to      .
    A．survive the emergenciesB．avoid a bear attack
    C．deal with a chokeD．find our way

    As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
    Wash Your Hands
    And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
    Get Enough Sleep
    This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
    Keep Hydrated
    Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.
    Eat Immune-Improving Foods
    Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune
    system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
    Avoid Alcohol
    Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
    —————————————？
    Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
    Avoid Contact with Sick People
    If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
    Know When to Get Help
    A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
    小题1:To fight A/H1N1 infection, it’s helpful for us to_______ .
    A．sing “Happy Birthday” while washing hands
    B．eat more fatty foods and colorful fruits
    C．keep away from alcoholic drinks
    D．refuse communication with patients
    小题2:A suitable title for paragraph 7 might be _______.
    A．Support the Immune SystemB．Keep Physically Active

    小题3:The passage seems to suggest that we should_______.
    A．get enough sleep after eating fatty foods
    B．wash hands with soap after a cough or sneeze
    C．drink more water after drinking alcohol
    D．see a doctor immediately if you have flu-like symptoms

    Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,000km, but sound travels only 344m. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke come from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays（光线）left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute. In some cases the light from one of tonight’s stars started on its journey to you before you were born.
    Thus, if we want to be honest, we cannot say “ The stars are shining tonight.” We have to say, “ The stars look pretty. They were shining four years ago but their light has only just reached Earth.”
    小题1: Light speed is ________ than sound speed.
    A．millions times fasterB．a million times slower
    C．about millions of times fasterD．about a million times faster
    小题2:If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that _____.
    A．you can hear the gun before you see the smoke.
    B．sound does not travel as fast as light.
    C．the sound of the gun will reach you before the man fires his gun.
    D．sound travels about a million times faster than light.
    小题3:What does “ it” refer to?
    A．moon lightB．light raysC．the nearest starD．the moon
    小题4:The scientific way of saying “ The stars are shining tonight” should be________.
    A．the stars have been shining all the time.
    B．the stars seen tonight will be shining four years later.
    C．the stars were shining long ago but are seen tonight.
    D．the starlight seen today could be seen four years ago.

    Imagine living locked inside a closet. You can’t choose when and what to eat or how you will spend your time. You can’t even decide when the lights go on and off. Think about spending your whole life like this.
    This is the life of lab animals.
    Now consider the needs of these animals. Chimpanzees(黑猩猩),in their natural homes, are never separated from their families. They spend hours together every day. But in a lab, chimpanzees are put in cages alone. There are no families, only cold, hard cages, and loneliness that goes on for so many years that most of them lose their minds at last.
    Worse yet are the experiments. Animals are given diseases they would never normally get. Experimenters force-feed(给……强行喂食) chemicals to them, conduct repeated surgeries(手术),and much more, Think of what it would be like to put up with these and then be thrown back into a cage, usually without any painkillers. Often animals see other animals being killed right in front of them.
    Hundreds of thousands of animals are poisoned, blinded, and killed every year in product tests for shampoos, skin creams and new cancer drugs. Although more than 500 companies have stopped testing on animals, some of them still force chemicals into monkeys’ stomachs and rabbits’ eyes.
    Although some facilities are better than others at caring for animals—not every lab worker kills a mouse by cutting off its head with scissors—there are no happy animals inside laboratories. Will the lab life end? When will it end?
    小题1:The passage mainly tells us about       .
    A．animals’ lives in laboratories
    B．cruel experiments on animals
    C．the needs of animals in labs
    D．facilities used to care for animals

    ①are very cold, and in separate cages
    ②feel lonely locked inside a cage
    ③aren’t fed anything but chemicals
    ④are forced to undergo cruel tests
    ⑤are forced to eat chemicals
    A．①③④B．②③⑤C．②④⑤D．①④⑤
    小题3:We can infer from the passage that _________.
    A．some companies have found ways to replace animal tests
    B．animals normally get no strange diseases
    C．animals are happy in labs with better facilities
    D．painkillers can change the results of experiments
    小题4:The author’s attitude towards the future of animals for experiment can be described as _______.

    Toucans(巨嘴鸟), a kind of tropical birds known for its colorful beak, are very smart. In Mexico, my dad became friends with a toucan that was in a “walk in and see the birds” cage. The toucan was so smart that it knew how to get out. It just needed some human to help it. It almost flew out while we were leaving!
    I also noticed that all toucans have different beaks! They also have very long unique beaks with an extremely long tongue. It struts(大摇大摆地走) around with its chest sticking out and beak pointed forward. The toucan is a beautiful bird! The beak has a red tip (different shades on every one), but sometimes there is a little turquoise on the bottom half. Then, right where the beak separates there is a splotch of yellow. And the rest of the beak is green. The toucan takes very much pride of itself.
    The toucan eats fruit and seeds. The ramphastidae(the toucan family) is known for its long beak, and 37 species. Toucans also feed on insects, small lizards, bird nestlings and eggs. They nest in hollow trees where they incubate and care for their young.They are found in the woody areas.
    Of the various toucan facts, here is an odd one. Citizens of Central and South America associate the toucans with evil spirits. They think the birds can be the personification of evils. Where couvades(父代母育) is practiced, the father of a new child must not eat toucan flesh as it is believed to bewitch the new-born child. Yet the toucan can also be a tribal totem(图腾). So the medicine men use it as a symbol to fly to the spirit world.
    60. 小题1:Which of the following words is NOT suitable to describe toucans?
    A．IntelligentB．ConfidentC．DangerousD．Colorful
    61. 小题2:The second paragraph mainly talks about _______.

    C．what toucans look likeD．when toucans lay eggs
    62. 小题3:What does the underlined word“incubate”probably mean in paragraph 3?
    A．Hatch eggsB．Take coverC．Gather strengthD．Keep warm
    63. 小题4:We can learn from the last paragraph that _______.
    A．all citizens of Central and South America are afraid of toucans
    B．the toucans can also be used as medicine to cure diseases
    C．a new child must not eat toucan flesh because it is poisonous
    D．some people believe toucans can bring them misfortune

        Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
    There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families. （词数155）
    小题1:The early language had ________.
    A．a lot of problemsB．words and easy grammar

    Which gender is the most talkative? No matter what you answer, you are partially right.
    A recent Gallup Poll showed that both men and women believe that women possess the gift of talking and some even believe women are biologically built for conversation, but all of that is challenged in a research published in the November issue of Personality and Social Psychology Review.
    In a recent research by Campbell Leaper and Melanie Ayres, they collected all of the available evidence from decades of scientific study and systematically combined the findings into an overall picture of the differences between men and women regarding talkativeness.
    They found a small but reliable tendency(趋势) for men to be more talkative than women in certain cases, such as when they were conversing with their wives or with strangers. Women talked more to their children and to their college classmates.
    The type of speech was also explored in the research. The researchers discovered that, with strangers, women were generally more talkative when it came to using speech to ensure her connection to the listener, while men’s speech focused more on an attempt to influence the listener. With close friends and family, however, there was very little difference between genders in the amount of speech.

    A. Gallup Poll       B. Personality and Social Psychology Review
