     About ten men in every hundred have the trouble of color blindness in some way. Women are luckier,
only about one in two hundred is affected (感染) in this matter. Perhaps, after all, it is safer to be driven
by a woman.
    There are different kinds of color blindness. For example, a man cannot see deep red. He may think
that red, orange and yellow are all shades (影子)of green. Sometimes a person can't tell the difference
between blue and green. Only a few unlucky men may see everything in shades of green-a strange world
indeed.
    Color blindness in human beings is a difficult thing to explain. In only one eye there are millions of very
small things called "cones (锥状细胞)". These help us to see in the bright light and to tell differences
between colors. There are also millions of  "rods ( 杆状细胞)", but these are used for seeing when it is
nearly dark. They show us shapes but not colors.
    Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light
will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky.
With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of
the rods we can see shapes at night.
1. "Color blindness" means "______" in Chinese.
A. 盲目    
B. 无色    
C. 色盲    
D. 讨厌颜色
2. Some people say it's safer to be driven by women because ______.
A. women drive more carefully
B. women are better at driving than men
C. women can see things more clearly
D. there are fewer color-blind women
3. With the help of the "cones", we can ______.
A. tell different shapes  
B. kill insects
C. see in the dark    
D. tell orange from yellow
4. We can attract and kill mosquitoes by using a ______ light.
A. red    
B. yellow    
C. blue    
D. green
5. Which of the following sentences about color blindness is TRUE?
A. None of men can see deep red.
B. Not all of men have the same problem in recognizing colors.
C. None of men can tell the difference between blue and green.
D. All of men see everything in shades of green.

     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.

    B. The writer can give blood to B group people.

    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

    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"
