    Sweet potatoes are fat-free, high in fiber and full of the vitamins that research suggests reduce your risk of life-shortening diseases. To stay healthy, we must eat more fruits and vegetables, and sweet potatoes are a great source of beta carotene(胡萝卜素) and other carotenoids(which the body turns into vitamin A). According to a study of the diets of almost 90,000 nurses, eating about one cup a day of fruits and vegetables rich in carotenoids can cut your risk of stroke in half and reduce your risk of heart disease by 22 percent. Other research suggests beta carotene protects against breast, lung and stomach cancers.
    Beta carotene is the most famous member of the carotenoids family. In face, a medium-sized sweet potato contains nearly 12mg of beta carotene(anti-aging experts usually suggest 6 to 11 mg per day). Sweet potatoes are also a low-fat source of vitamin E. Research has linked high E diets with a lower risk of heart disease. This vitamin pill in an orange jacket also packs a vitamin C punchit which has more C than apricots (a kind of fruit). Research suggests that vitamin C protects against ailments (小疾) ranging from cataracts(an eye disease) to cancer. In addition, a UCLA (University of California Los Angeles) study linked high vitamin C diets with a longer life. Recent studies have showed that antioxidant Vitamins C, E and beta carotene fight a fierce battle against free radicals (自由基），which cause cell damage and lead to various illness. Therefore, to keep fit, eat more sweet potatoes.

    A. fiber, beta carotene, other carotenoids, Vitamin E and C
    B. beta carotene, other carotenoids, fiber, Vitamin A and E

    B. protect against breast, lung and stomach cancers
    C. protect against ailments ranging from cataracts to cancers
    D. you stay healthy and reduce your risk of life-shortening diseases
    74. “ This vitamin pill in an orange jacket” in the passage refers to______.
    A. sweet potato     B. vitamin C pill

    Ship tourism to Antarctica is on the rise: More than 35,000 tourists are expected to visit Antarctic this summer. In 1992-1993, 6,750 visited Antarctica, according to the Antarctica Treaty. All of this tourism, however, is putting both tourists and the environment in great danger.
    Among the tourist ships that visit the continent, the Explorer, a Canadian ship, was one of the first. Put to use in 1969, it was built to carry tourists to Antarctica. Last week, however, it became the first commercial passenger ship to sink beneath the waters. Fortunately, all of the passengers and crew members were rescued from the ship. However, the sunken ship endangered the Antarctic’s fragile(脆弱的) environment. The ship was estimated to be holding 48,000 gallons of fuel.
    The accident was not unexpected. Both the US and UK had warned a conference of the Antarctic Treaty member countries in May that the tourism situation in this area was a potential disaster. The US said in a paper, people “should take a hard look at tourism issues now, especially those related to ship safety.” Although the Antarctic seas are relatively(相对地) calm, floating ice causes a potential threat to ships. The owner of the Explorer blamed the sinking on a fist-like hole in the ship created by ice.
    Many of the other large ships now visiting Antarctica are not designed especially against thick ice. Such ships generally can only come to the continent in summer. But the tourist rush is pushing ships into dangerous situations. “The increasing number of ships operating in Antarctic means that the ship are under great pressure to get there in time for the key visiting sites,” the British government wrote in a paper at the meeting of member countries.
    As a natural frontier, Antarctica is in a messy legal situation. There are no obvious answers as to who is responsible for dealing with the threat that tourist may cause to human life and the environment.
    There is no coast guard for Antarctica. Do we want it to become Disneyland, or do we need some controls?
    76. Which of the following is true according to this passage?
    A. Antarctica tourism has a history of about 17 years
    B. The number of tourists to the Antarctic is over 5 times as large as that of 17 years ago.
    C. The tourism boom has caused holes in the floating ice in the Antarctic.
    D. The Antarctica Treaty is responsible for the problem.
    77. The sinking of the Explorer____________.
    A. led to a conference about the tourism situation in the Antarctic.
    B. was caused by the rough seas
    C. had been predicted
    D. did harm to the Antarctic.
    78. It can be inferred from the passage that_________.
    A. a Disneyland will be built in the Antarctic
    B. fewer people are visiting the Antarctic because of the warnings given
    C. not all the ships are suitable to go to the Antarctic
    D. some ships take risks visiting the Antarctic in other seasons rather than in summer
    79. In this passage, the writer suggests that___________.
    A. people had better not make a tour of the Antarctic
    B. ships to the Antarctic should be built strong enough
    C. there should be legal controls over tourism in the Antarctic
    D. the Antarctic’s environment is fragile
    80. What attitude does the writer hold towards Antarctic tourism?
    A. Supportive.     B. Positive.       C. Indifferent.        D. Anxious.

    Bedazzling (眼花缭乱) with their bright colors and eye-catching displays, fireworks light up our night skies during the holidays. However, these crowd-pleasers can have some damaging side effects.
    Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals — as well as some humans.
    The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead — all found in fireworks — have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin(毒素) limits of the United States Clean Air Act.
    Once all those chemicals come back down to the ground, they can cause problems too. Debris (碎片) from the fireworks falls to the ground, where animals can burn their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources.                              
    Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started:
    ? Sky lanterns — a tradition that originated long ago in the most-populated Asian country.
    ?  Party crackers — a favorite in the United Kingdom — give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers.
    ? Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns (号角) and blow up a storm! 
    46. The advantages of fireworks can be seen below EXCEPT that _____.
    A. the special sounds of fireworks excite people
    B. debris from fireworks can even find its way into water
    C. the pretty and bright colors add to the beauty of night skies
    D. fireworks are enjoyed as one of the crowd-pleasers
    47. Which of the following is NOT true according to the passage?
    A. Copper compounds are needed to make green in fireworks.
    B. Chemicals in fireworks are both poisonous and dangerous.
    C. Too much gases from fireworks can result in acid rain.
    D. Chemicals in fireworks are harmful in the air and on the ground.
    48. All the underlined words are probably _____________.
    A. mineral materials                             B. tiny solids
    C. chemical elements                                   D. broken pieces
    49. What is implied from the passage?
    A. Gunpowder in fireworks makes loud booming noises.
    B. It must be Indians who first started to hang sky lanterns.
    C. Fireworks does less harm in the air than on the ground.
    D. Fireworks can even break the balance of nature.
    50. What can be concluded as the writer’s attitude towards fireworks?
    A. It is not allowed to set off fireworks except during the holidays.
    B. Fireworks should be banned and replaced by some other means.
    C. Night is the best time to set off fireworks and see the pretty colors.
    D. You cannot set off fireworks unless you come up with new ways.

    B
    Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist’s nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
    It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats
    If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight cavities.
    55．What is the main purpose of this passage?
    A. To discuss how cavities can be treated.
    B. To point out the problems with Halloween celebrations.
    C. To tell parents what sweets are less damaging to their children’s teeth.
    D. To teach parents the meaning of Halloween candies for their children.
    56．Why are hard candies especially bad for teeth?
    A. They may break the child’s teeth.
    B. They contain too much sugar.
    C. They help bacteria to produce tannins.
    D. They stay in the mouth for a long time.
    57．According to the passage, which of the following is a better choice for Halloween treats?
    A. Chocolate.                     B. Crackers.                        C. raisins.                            D. Potato chips.
    58．According to the passage, which of the following is true of tannins?
    A. They are produced when the bacteria digest the food.
    B. They help to get rid of some bacteria in the mouth.
    C. They help chocolate to dissolve more quickly.
    D. They destroy the surface of the teeth.

    Here’s an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What’s more, you don’t even need to touch the egg to get it to go in!
    For this experiment you will need:
    ·a hard-boiled egg
    ·a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well)
    ·a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper
    ·a match
    Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth.
    Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze(挤) through the mouth and into the bottle.
    As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直径) of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle’s opening.
    Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals(封住) the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts(紧缩), and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!
    小题1:The best title of this passage can be      .
    A．An interesting storyB．The pressure of the air
    C．Egg in a bottleD．Egg, bottle and match
    小题2:What don’t you need in this experiment?
    A．Eggs.B．Water.C．Bottles.D．Paper.
    小题3:Why will the egg break into pieces while entering the bottle?
    A．Because of the burning paper.
    B．Because the diameter of the egg is too larger than that of the bottles opening.
    C．Because it is cool inside the bottle.
    D．Because the pressure of the air inside is larger.
    小题4:What is the most important to get the egg into a bottle?
    A．A match. B．A fruit-drink bottle.C．The pressure of the air.D．The burning paper.

    Hidden in our subconsciousness (潜意识) is a perfect mental picture. We see ourselves on a long trip that goes across the continent. We are traveling by train. Out the windows, we think in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle feeding on a distant hillside, of smoke pouring from a power plant, or row upon row of corn and wheat, of flat lands and valleys, of mountains and rolling hills, of city skylines and village halls.
    But uppermost in our minds is the final destination. On a certain day at a certain hour, we will pull into the station. Bands will be playing and flags waving. Once we get there, so many wonderful dreams will come true and the pieces of our lives will fit together like a completed jigsaw（拼图玩具） puzzle. How restlessly we pace the aisles(通道), condemning the minutes for loitering --waiting, waiting, waiting for the station.
    “When we reach the station, that will be it!” we cry. “When I’m 38.” “When I buy a new 450SL Mercdes Benz!” “When I put the last kid through college.” “When I have paid off the!” “When I get a promotion.” “When I reach the age of retirement, I shall live happily ever after! ”
    Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The true joy of life is the trip. The station is only a dream. It constantly outdistances us.
    “Relish(appreciate) the moment” is a good motto, actually it isn’t the burdens of today that drive man mad. It is the regret over yesterday and the fear of tomorrow. Regret and fear are twin thieves who rob us of today.
    So stop pacing the aisles and counting the miles. Instead, climb more mountains, eat more ice cream, swim more rivers, watch more sunsets, laugh more and cry less. Life must be lived as we go along. Then the station will come soon enough.
    小题1:Why does the author describe the mental picture?
    A．To lead us into a perfect world.B．To let people enjoy the scenery.
    C．To introduce an actual trip of his.D．To compare it to our life’s journey.
    小题2:How do people feel when they’re on their trip?
    A．Puzzled.B．Happy.C．Relaxed.D．Impatient.
    小题3:What does the author mean by “Regret and fear are twin thieves who rob us of today” in Line 2 Paragraph 5?
    A．Regret and fear are responsible for the loss of today.
    B．We must be careful of the two thieves: regret and fear.
    C．regret and fear stop us from enjoying our present life.
    D．We’re frequently challenged by the two : regret and fear.
    小题4:Why does the author write the passage?
    A．To teach us a good lesson.B．To tell us the right attitude to life.
    C．To advice us to forget our worries.D．To stop us wandering along the aisles.

    Do you know the cold?
    Everybody knows what happens when you catch a cold. First you sniffle(抽鼻涕) or get a more throat. Then you sneeze. After coughing and blowing your way through the next few days it’s over---until next time
    Do you know what causes a cold, how it is spread or how to help prevent it? And which of the many medicines is best for your cold?
    There is no known cure for the common cold. Once you catch a cold, your body usually produces antibodies(抗体) to the virus which caused the cold. These antibodies help the body develop resistance（抵抗力) to the virus if you catch it again. Unfortunately, over 200 different viruses cause the common cold. These viruses may change over time, so your resistance to them reduces. The large number of viruses and the fact that they change help explain why there is no cure for the common cold and why you will suffer colds in the future.
    The colds increase in winter(usually between Septenber and March) but Not because of the cold! Cold weather has not been shown to increase the number of colds. People spend more time indoors in winter. They are therefore more likely to come into physical contact with each other and spread the disease. All these ideas remain to be proven. No one has been able to discover what really causes these colds
    Common colds are spread by sneezes or by direct contact with a cold sufferer, usually when two people’ hands touch or an object is passed from one person to another. Sneezing spreads colds when someone sneezes near other people, or sneezes on objects which others later touch. A cold virus can survive up to three hours on hard surfaces.
    The simplest and most effective way to lower the risk of catching a cold is to wash your hands frequently. Another important step in cold prevention is for cold sufferers to get rid of used tissues immediately after use.
    1.From the passage, we can know____________.
    A. a cold virus can survive up to four hours      
    B. most of people know how to cure a cold
    C. there are more colds in November than in May  
    D. all of us catch more than one cold a year
    2.According to the passage, people tend to catch a cold___________.
    A. because they don’t take exercise in winter    
    B.if they stay outdoors in freezinf cold winter
    C. if they stay indoors more often in winter  
    D.because the viruses of colds usually exist in winter
    3.We can know colds sre spread through____________.
    A. air and touching     B. coughs and objects   C.two people    D. a person and his hands
