When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is
very important. People have always 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"
(输血). The blood goes from the arm of the healthy person into 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 may become ill. You may need blood. The "blood bank" will give it to you.
B. have lost a lot of blood
C. are not given the right kind of blood
D. are AB-group people
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
B. the four groups of blood
C. where the blood bank is
D. what "blood transfusion" is
B. If I have B-group blood, I can give my blood to a person with AB-group blood.
C. If I have A- group blood, I can only give my blood to others with the same blood.
D. If I have O-group blood, I can get blood from anyone else safely.
B. something about 4 kinds of human"s blood
C. something about blood transfusion
D. all of the above

举一反三
answer, aren"t they?
Is the sky blue? The sky has no color. We know that there is air around the world. When planes fly,
they need air to lift their wings. Planes can"t fly very high because the air gets thinner when they go up
higher. If we go up about 1,200 kilometers from the earth, we"ll find no air there.
When we talk about the sky, we usually mean the atmosphere around the earth. It is like a very thick
"cover" over the earth and keeps it warm. Without the "cover", the earth would be a very cold place and
nothing could live on it.
Looking up above us, you will see the blue sky with white clouds. It is usually light blue, but the sky
would be dark blue if you go to the top of the highest mountains. And you will see fewer clouds between
you and the sun.
And if you sit in a spaceship high above the earth, there is no air at all. The sky would be so dark that
its color would be black.
Sometimes the sky doesn"t look blue. When the sun rises and falls, you will see red, orange, and other
colors in the sky. These are the most beautiful moments of the day.
Now you may understand that we see colors because the air scatters (散射) the sunlight. Light travels
through the air. Without air, there would be no light and no colors.

month in China.Is your school doing anything to celebrate? You should join! That way, you can learn

"What time is it?" Then people can tell me the exact time.But before the invention of clocks, it was
very difficult.One way people told the time was by using sundials, but it was impossible to tell the time
on cloudy days or at night.
The first mechanical(计时)clock was invented in China by Su Sung in 1088.The first clock in
Europe was invented 195 years later, at the end of the 13th century.And in Britain, 67 years later, the
alarm clock was invented in Germany.
The first watch was invented in Italy in 1462. Early watches were different from today"s in two main
ways.First, they only had an hour hand.Second, you could not wear them on your wrist. (手腕)You
had to keep them in your pocket- that"s why they were called "pocket clocks".
The first wrist watch came from Switzerland 328 years after the first pocket clock, but nobody bought
them.They did not become popular for a hundred years.
Digital clocks and watches came from the United States and are the new popular inventions in
time-keeping.Shops all over the world started to sell them in 1971.
