         About 130 years ago, Thomas Edison of the US invented the light bulb (电灯). Edison's bulb has turned
    night into day ever since. But today, many want to turn the light off.
         The European Union (欧盟) recently decided that by 2009, people should stop using the Edison-style light
    bulb. Instead, they should use compact fluorescent lamps (小型荧光灯, CFLs节能灯).
        "CFLs save energy and last longer. They can save money in the long run," said a British official. CFLs use
    67 percent (67%) less electricity than the older bulbs. They last up to 10 times (倍) longer. Scientists say that
    if everyone used CFLs, electricity use would be cut by 18 percent. There would also be much smaller amounts
    of greenhouse gases (温室气体) given off.
         But it's difficult to make people change their lighting habits. First the CFLs are more expensive. They cost
    eight times the price of the older bulbs. Many people don't like the CFL bulb. They find it too bright. You
    cannot change the light of a CFL, either.
         CFLs have been around for several years. However, the older lights still make up about two-thirds (2/3) of
    total (全部的) light bulb sales.
    (     )1. Thomas, Edison invented the CFL bulb 130 years ago.
    (     )2. Countries in the European Union will not use Edison-style bulbs by 2009.
    (     )3. Using CFLs helps protect the environment.
    (     )4. If you get an older bulb for l Euro (欧元), the CFL bulb will cost you 8 Euros.
    (     )5. CFLs have been widely used instead of the older bulbs for several years.

         Is human blood all the same? "Yes." You may say. "It's all red."
         Well, it's not as simple as you might think.
         Blood is made up of different parts, such as red blood cells (红血球), white blood cells and platelets (血小板).
         Two chemical molecules (分子) on the red blood cells make people's blood different. Scientists mark one
    molecule "A" and the other molecule "B". According to which and how many molecules are on the red cell,
    scientists divide blood into four types: A, B, AB and O.
         Your blood type will stay the same all your life.
         Scientists have been wondering if there are some links (联系) between people's blood types and their
    personalities, but they are not certain.
         But some say that people with the same blood type may have things in common.
         What's your blood type? Do you have family members or friends who are of the same type as you?
    Read the following. 
         People with Type A: They look peaceful from the outside. But they ask too much of themselves that
    they may be very nervous inside. They get happy or sad easily. Sometimes they are shy but always very
    careful. They can easily win people's trust.
         People with Type B: They have strong minds. Once they start a task, they don't give up easily. They'll
    try their best to finish it and do it well. Type B people always try to make themselves different from others.
    They want to do things in their own way.
         People with Type AB: They are maybe the strangest among all blood types. They can be both open and
    shy, noisy and quiet at the same time! They are responsible and always ready to help others.
         People with Type O: They are open and good at making friends. They always start tasks but don't always
    finish them. They have lots of new ideas and love to be the centre of attention. They always strongly believe
    in themselves.
    1. The blood types are decided by the kind and amount of molecules _______.
    2. Scientists are _______ about the relations between blood and personalities.
    3. If you are with Type B, you might _______.
    4. If a person is both open and shy, noisy and quiet at the same time, he or she might be with _______ blood.
    5. The best title of the passage is _______ and Personalities.

         When you cut your skin, you bleed (流血). If a person loses a lot of blood (血), he will become ill and
      may die. Blood is very important. People have known that. At one time, some people even drank blood
     to make them strong!
         When doctors understand how blood goes around inside the body, they try ways of giving blood to
     people who need it. They take blood from the healthy people and give it to people who need it. This is
      called "blood transfusion". The blood goes from the arm of the sick person.
         But there are two problems. First, it does not always work. Sometimes people die when they have
      blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four
     groups - O, A, B and AB. We all have blood of one of these groups. They also find that they can give any
      kind of blood to people of group AB. But they find that they must give A group blood to A group people
      and B group blood to B group people. I have O group blood and the doctor told me that I could give
     blood to anyone else safely.
         There is another problem. To give blood of the right kind, doctors have to find a person of the right
     blood group. Often they can not find a person in time. If they have a way to keep the blood until someone
      needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for
      fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the
      end they find a way of keeping blood for a very long time.
         We call a place where we keep money a "bank". We call a place where we keep blood a "blood
      bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you
      may stop someone from dying. Or perhaps one day you become ill. You may need blood. The "blood
      bank" will give it to you.
    1. From the passage, we learn that sometimes people die when they have blood transfusions because they _____.
        A. are unhealthy people                      
        B. have lost a lot of blood
        C. are not given the right kind of blood          
        D. are AB group people
    2. Which of the following is true?
        A. Doctors can give any kind of blood to the writer.  
        B. The writer can give blood to B group people.
        C. The writer has never had a blood transfusion.    
        D. The writer has the same kind of blood as his father.
    3. People set up the "blood bank" so that they can _____.
        A. give the right kind of blood to the people who need it in time.
        B. keep different groups of blood as much as possible.    
         C. make it easier to sell or buy blood
         D. keep blood for more than twenty hundred years
    4. From the last paragraph (段落) of the passage, we learn that _____.
        A. the writer thinks it's good to give blood to a "blood bank"
        B. we may become ill if we give blood to a "blood bank"
        C. many people died because they lost a lot of blood    
        D. blood is more important than money
    5. The writer doesn't talk about _____ in the passage.
        A. how important blood is to us     
        B. the four groups of blood
        C. where the blood bank is    
        D. what " blood transfusion" is
