选项。                                                        The War Against Sand
     Imagine living on the edge of a vast desert, which is moving quietly closer to your village every day
and covering your fields. The desert is on the move. This is called desertification.
     Desertification occurs in regions close to an already existing desert.     1     The first is over-use of
water in the area. There is not enough water in any case, and if it is not carefully used, disaster can follow. As time goes on, water shortages make farming more and more difficult. In some places, locals can
remember local lakes and marshes which were once the homes for all kinds of fish and birds.     2    
Farmers leave the land, and fields are replaced by deserts.
     The second cause is misuse or over-use of the land.     3     Ploughing(耕) large fields and removing
bushes and trees means that the wind will blow away the soil. Once the soil is lost, it is hard to replace,
and if there is rain, it has nowhere to go, and brings no benefit.
         4     Every spring, the skies over some of eastern cities, thousands of kilometers away from the
deserts, can be darkened by sandstorms. Dust from deserts can have a great effect on weather systems. While desertification is perhaps being partly caused by global warming, these sandstorms can make
global warming worse by adding to what is known as the greenhouse effect.
     What can be done to slow down or stop the process of desertification? A great deal of work is
already under way. Obviously first steps are to find new water sources.     5     Some types of grass also
hold the soil together, and stop the wind taking it. Without these efforts, it will be harder and harder to
stop the world"s deserts in their tracks, and more and more farmers will give up and head for cities. The
lesson to be learnt lies beneath the sand.

     Hi, boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.
     First, eat different foods, especially fruit and vegetables. You may have a favorite food, but you"d
better eat something different; if you eat different foods, you will probably get more nutrients your body
needs.
     Second, drink water and milk as often as possible. When you"re really thirsty, cold water is the NO.1
choice. Milk is a great drink that can give you more calcium your body needs to grow strong bones.
     Third, listen to your body. How do you feel when you are full? When you are eating, notice how your
body feels and when your stomach feels comfortably full. Eating too much will not make you feel
comfortable and make you fat.
     Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using
computers. It is good to take more exercise such as basketball, bike riding and swimming. You can"t
watch TV for more than two hours a day.
     Fifth, be active.One thing you"d like to do as a kid is to find out which activity you like best. Find ways
to be active every day.

     Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮)
since 1981. And freezing weather is hitting the Deep South, including Florida"s orange groves and beaches.
Whatever happened to global warming?
     Such weather doesn"t seem to fit with warnings from scientists that the Earth is warming because of
greenhouse gases. But experts say the cold snap doesn"t contradict global warming at all - it"s just a
temporary phenomenon in the long-term heating trend. "It"s part of natural variability," said Gerald Meehl,
a senior scientist. With global warming, he said, "we"ll still have record and cold temperatures. We"ll just
have fewer of them."
     Scientists say man-made climate change does have the potential to cause more frequent and more
severe weather extremes. But experts did not connect the current cold snap to climate change.
     So what is going on?
     "We basically have seen just a big outbreak of Arctic air over populated areas of the Northern
Hemisphere", Arndt said.
     In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic
and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has
become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it
brings air up from the south, you get warm weather. In fact, record highs were reported this week in
Washington state and Alaska.
    But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from
the north. And that"s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in
mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time
to time, but it is not clear why it"s so strong right now.
1. What is the main idea of the text?
A. Freezing weather is hitting the Deep South.
B. We"ll still have record cold temperatures.
C. The air flow has become a zigzag pattern.
D. Cold snap doesn"t contradict global warming.
2. With global warming, we will ____.
A. also meet with severe cold snap
B. have more hot temperatures forever
C. never experience cold temperatures
D. have more cold temperatures
3. Beijing had its biggest snowfall since 1951 because of ____.
A. a fence from the Arctic
B. a cooling trend in climate
C. a big outbreak of Arctic air
D. its large population
4. We can conclude that ____.
A. not all the parts of the Northern Hemisphere are cold in face of the cold snap
B. the zigzag pattern arises naturally accidentally
C. Beijing will get cold weather next year
D. Washington state and Alaska will not face cold weather next year.

     Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They
warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and
possibly cancer.
     __1 _ Some people express anger openly in a calm reasonable way. Others burst with anger, and
scream and yell. But other people keep their anger inside. They cannot or will not express it. This is
called repressing anger.
     For years many doctors thought that repressing anger was more dangerous to a person"s health than
expressing it. They said that when a person is angry, the brain release the same hormones (荷尔蒙).
They speed the heart rate, raise blood pressure, or sugar into the blood, etc. __2__
     Some doctors say that both repressing and expressing anger can be dangerous. They believed that
those who express anger violently may be more likely to develop heart disease, and they believe that
those who keep anger inside may face a greater danger of high blood of pressure.
     __3__ They say the first step is to admit that you are angry and recognize the real cause of the anger,
then decide if the cause is serious enough and get angry about. If it is, they say, "   4  . Wait until your
anger has cooled down and you are able to express yourself calmly and reasonably."
     Doctors say that a good way to deal with anger is to find humor in the situation that has made you
angry. __5__

     Good health is the most valuable thing a person can have, but one cannot take good health for
granted. It is important to remember that the body needs proper care in order to be healthy. There
are three things that a person can do to help stay in good shape: eat right food ,get enough sleep,
and exercise regularly.
     Proper nutrition (营养) is important for good health. Your body cannot work well unless it
receives the proper kind of “fuel”(燃料).Don"t eat too much food with lots of sugar and fat. Eat
plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are
very important because they provide necessary vitamins (维他命) and minerals. However, don"t
over eat. It is not helpful to be overweight.
     Getting the proper amount of sleep is also important. If you don"t get enough sleep, you feel
tired and easily get angry. You have no energy. Over a long period of time a little a amount of
sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven
to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your
mind will be sharp.
     Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles,and prevents
you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise
program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most s
ports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running
and so on are good examples. Sports are not only good for your body, but they are enjoyable and
interesting, too.
     If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world
would be a happier and healthier place. We would all live to be much older and wiser.
