     The Internet is a big place. Nobody has the time to look at every webpage to find something. Search
engines (搜索引擎) like Yahoo give us a lot of help.
     Two Stanford University students, David Filo and Jerry Yang started it in 1994. They made a list of
their favorite webpages. When their list got bigger, they made a database (数据库) to keep all the
information. They let everyone use it for free. Soon, thousands of people were using it.
     They then made a new kind of software (软件). It looked at web pages all over the Internet. It could
then take that information and arrange it for someone to look at. If you look for "animals", the engine will
give you a list of web pages with those words.
      Yahoo became a public (公共的，公开的) company in 1996. Filo and Yang, still young men, became
rich. As the company grew, they went on working hard. They improved the software. They also put
more uses in, like shopping, free E-mail, booking tickets and so on. They started Yahoo in many different

     The sun is always shining. But it can only shine on one side of the earth at a time. It can not light up
(照亮) the other side of the earth at the same time.
      All day the stars are in the sky, but the light from the sun is so bright that you can not see them. When
the sun is gone, the stars are bright enough to see. Stars look very small but some are even bigger than the
sun. Big things look little when they are far away. In the sky planes look like toys. But on the ground you
can see that they are big. Stars look very small because they are far away. The sun is closer to us than the
other stars. So it looks bigger.

     When you cut your skin, you bleed (流血). If a person loses a lot of blood (血液), 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.

      Every 30 seconds there is an earthquake. But don't worry because most are so weak that they cannot
be felt. Only a few big ones hurt people. Many earthquakes happened in China, such as the big one in
Sichuan last month. Thousands of people died in it. So it's important to know what to do when one hits.
Here are some tips on how to stay safe in an earthquake.
      a. If you are indoors during an earthquake, hide under a desk. Stay away from windows and anything
that could fall on you.
      b. If you are outdoors, move to a clear place. Try to be away from trees, signs, buildings and
streetlights. These could fall on you.
      c. If you are in a shop and far from the door, don't try to run outside and rush for exits (出口).
Everyone will be doing that and you'll find it hard getting out. Don't get into a lift during an earthquake.
Just hide under some strong cover near you.
      d. When an earthquake has ended, be careful because aftershocks may still happen. These are just as
dangerous as the earthquake itself. So stay under the desk until you make sure it's safe to get up.
      e. If you are at home and you smell gas (煤气), open the windows and get out of the building as quickly
as you can. A gas line in your house may be broken. This could be very dangerous.
