         NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences.
    Violence and traffic accidents can leave people with terrible physical and emotional scars. Often the
    experiences in nightmares appear repeatedly.
         Now American researchers think they are close to developing a pill, which will help people forget
    bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it
    might reduce, or possibly wipe out, the effect of painful memories.
         In November, experts tested a drug on people in the US and France. The drug stops the body
    releasing chemicals that fix memories in the brain. So far, the research has suggested that only the
    emotional effects of memories may be reduced, not that the memories are wiped out. They are not
    sure to what degree people's memories are affected.
         The research has caused a lot of argument. Some think it is a bad idea, while others support it.
    Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They
    say that there are many people who suffer from terrible memories.
         "Some memories can ruin people's lives. They come back to you when you don't want to have them
    in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a
    professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
          But those who are against the research say that maybe the pills can change people's memories and
    changing memories is very dangerous because memories give us our identity. They also help us all avoid
    the mistakes of the past.
         "All of us can think of bad events in our lives that were terrible at the time but make us who we are.
    I'm not sure we want to wipe those memories out." said Rebecca Dresser, a medical ethicist (伦理学家).
    1.The passage is mainly about        .
    A. a new medical invention
    B. a new research on the pill
    C. an argument about the research on the pill
    D. a way of wiping out painful memories
    2. The drug tested on people can        .
    A. cause the brain to fix memories
    B. stop people remembering bad experiences
    C. wipe out the emotional effects of memories
    D. prevent body producing certain chemicals
    3.We can infer from the passage that        .
    A. Experts are not sure about the effects of the pills.
    B. the pill will certainly stop people's emotional memories
    C. taking the pill will do harm to people's physical health
    D. the pill has already been produced and used by the public America
    4.Which of the following does Rebecca Dresser agree with in the last paragraph?
    A. some memories can ruin people's lives.
    B. people want to get rid of bad memories.
    C. experiencing bad events makes us different from others.
    D. the pill will reduce people's sufferings from bad memories.
    5.You may probably read the passage in             .
    A. a guidebook              
    B. a textbook
    C. a medical magazine      
    D. a science fiction

    Write NO MORE THAN THREE WORDS for each answer.
         With an obese (very fat) or overweight population of 66% percent of adults, teaching your kids healthy eating habits is one of the most important things you can do for them as a parent.
          Most parents and children claim that breakfast is part of their everyday routines. But for many more
    than you might think, it's not. Children who eat breakfast have higher math grades, have improved reading scores and basically perform better in school. They also tend to have healthier bodies in general, with
    better-controlled weight levels.
         When you take them to the grocery store with you, it's doubtless that your children will request the
    most sugar-filled, fat-injected products on the shelf. But these are not the ones to have in your home－you should avoid buying them at all. Be sure your kids have healthy snacks.
          Yes, kids like white bread. But any kid can get used to the taste of whole grains. It just takes a little
    practice. Look for white bread, and add other whole grains into their diet. Start toasting their sandwiches. When it's toasted, it'll be that much harder for them to tell the difference in taste.
          It's simple, it's true, and it's something you already know: kids who get plenty of exercise are healthier kids. Set limits on the amount of time your child may spend in front of the television or computer screen.
    Sign them up for plenty of sports and outdoor activities. And best of all, get involved in sports and exercise with them.
         One of the best things you can do to establish healthy eating habits in your kids is to have them yourself. You can tell your kids every day to eat healthy foods, but if you don't do the same thing yourself, the
    lesson will never stick.

         Write NO MORE THAN THREE WORDS for each answer.
         Tomatoes are the world's most popular fruit rich in nutrition like Vitamin A, C, fibre and lycopene
    (番茄红素). Researchers have found that consuming lycopene helps in preventing cancer. Tomato
    also helps in keeping the skin healthy and young by protecting from harmful rays. Since lycopene is
    present in the cellular wall of tomato, it is better to consume cooked tomato to have higher concentration
    of lycopene. So tomatoes are a wonderful fruit.
         Then how to grow tomatoes? First, there should be regular and even watering in the fields where
    tomatoes grow. You can also add fertilizer to have better results. Plant the tomato plants with enough
    space(for example 2 to 3 inch space)between each other to lessen spreading of disease and pests and
    help the fruits get enough sunlight. Provide support like pole when the plants grow up to prevent from
    disease and to increase the crop product.
         In order to make your tomatoes grow well, you should take some useful tips. For example, choose
    variety based on the season and soil type that you are growing. Planting site should have enough sunlight
    to have more fruits. Prune(修剪)the tomato plants if necessary to maintain a manageable size. Check
    tomato plants regularly for any kind of pests and diseases.
        To people's regret, tomatoes possibly suffer from some diseases during their growth. So you must try
    your best to prevent them. Soil should be free from debris(残骸)of earlier plant remains and should be
    treated first before tomato plantation like solarizing(晒) to prevent from pests. It is always better to
    choose resistant plant varieties and follow crop rotation(轮作)as far as possible.

         No matter what he is doing, every human being gives body heat. The usual problem is how to dispose
    of     it. But the designers of the Johnstown campus of the university of Pittsburg set themselves the opposite
    problem-how to collect body heat. They have designed a collection system which uses not only body heat
    but also the heat given off by such objects as light bulbs and refrigerators as well. The system works so
    well that no conventional fuel is needed to make the campus's six buildings comfortable.
         Some parts of most modern buildings-theatres and offices as well as classrooms-are more than heated
    by people and lights and sometimes must be air-conditioned even in the winter. The technique of saving
    and redistributing it is called "heat recovery". A few modern buildings recover heat, but the university's
    system is the first to recover heat from some buildings and reuse it in others.
         Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student
    studies, the more heat his body gives off. Male students emit more heat than female students, and the larger
    a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown
    campus would be a hard-working, overweight male genius    .

    1. The underlined words "dispose of" in the first paragraph mean _____.
    A. reuse
    B. collect
    C. get rid of
    D. place in suitable positions
    2. According to the passage,the following statements are true EXCEPT _____.
    A. fat,male and hard-working students give off more heat
    B. six buildings are heated by the heat system on the Johnstown campus
    C. the heat is supplied by human bodies, other heat-omitting objects
    D. the heat from human bodies, other heat-omitting objects is only used in cold winter
    3. From the passage, we can infer that _____ would produce the LEAST heat.
    A. a large female who does not study hard
    B. a thin male who studies hard
    C. a thin female who does not study hard
    D. a large male who studies hard
    4. The underlined sentence is _____.
    A. indifferent
    B. objective
    C. serious
    D. humorous

         No one knows yet the accurate number of lives which have been lost in this terrible fire. But reports
    suggest that it is more than one hundred.
         A wall of flames fifty feet high and at least one hundred and fifty miles wide is now racing towards
    the forests and rich farmlands of southern Victoria. Towns less than one hundred miles from Melbourne
    will be in danger unless the wind changes. People are rushing excitedly into the streets. The police have
    warned them not to see the fire but many people are doing so.
         The cause of the fire is unknown. No rain has fallen in this part of Australia for three months, and the
    hot, north-west wind from the great central desert is blowing at more than thirty miles an hour.
         The firefighters are travelling to the fire by road, rail and air. But it is not easy to get there. Flames and
    fallen trees have cut off or blocked roads and railway lines. The thick smoke often prevents them from
    finding the air strips (飞机跑道).
         It is said that the fire has brought the greater danger to the country since the Second World War.
    1. By the time the article was written, the fire ____.
    A. had just broken out
    B. had been put out
    C. was spreading violently (猛烈地)
    D. was coming to an end
    2. The writer wrote this article mainly to tell people ____.
    A. the fire was terrible and dangerous
    B. it was impossible to put out the fire
    C. more than one hundred people died of the fire
    D. to join in the fight against the fire
    3. In the 4th paragraph, the writer suggested that ____.
    A. the fire would soon be controlled by the firefighters
    B. it would be very difficult to put out the fire
    C. the government was paying great attention to the fire
    D. the fire had caused great losses and the airport was in danger
    4. The underlined word "accurate" in the first sentence has the same meaning as ____.
    A. recent
    B. whole
    C. rough
    D. exact

         No air means death. Although we can't see it, there is air around us. So air is everything and it gives life
    to every living thing. Bad air makes people ill. We must have fresh air to keep us in good health.
         In the city there are a great many people and there are too many cars running on the roads. The gas which
    the cars spread out is full of poison. Every day we breathe it in again and again. This makes us feel sick.
         Besides so many cars, there are many factories too. From the chimneys of these factories, we get the
    smoke usually in black and grey colour. This kind of smoke, when it mixes the air, is dangerous to our health.
    It is because smoke contains many poisonous solids and gases. So in order to keep us healthy we have to go
    out to the countryside to breathe more fresh air. Or we can go up hills to get more fresh air.
    1. Which of the following best explains that no air means death?
    [     ]
    A. Air gives life to every living thing
    B. Air can't be seen anywhere around us
    C. Bad air makes people sick
    D. Fresh air keeps people healthy
    2. According to the passage, we know that            .
    [     ]
    A. going up hills is very good to our health
    B. smoke from chimneys is more serious than gas from cars
    C. We shouldn't go out of doors as much as possible
    D. A great many people have to breathe air again and again
    3. The best title for the passage is            .
    [     ]
    A. Fresh Air
    B. The Use Of Air
    C. Breathing Air
    D. Bad Air
