Why do earthquakes happen? Scientists explain that the outside of the earth
is made of a number of different plates(極塊). For example, at San Francisco the
Pacific Plate which is moving towards the northwest meets the North American
Plate. The Pacific Plate is moving very   slowly-at 5. 3 centimetres a year.
Sometimes these two plates stop and do not move for years. Then suddenly, they
jump and an earthquake is felt. As the movement of these plates,West America
near the sea has always been a bad place for earthquakes. When the 1906
earthquake happened, the Pacific Plate jumped 5-6 metres to the north.
　　We cannot stop earthquakes, but we can do things to make sure they don't
destroy(毀壞) the whole of cities. First,it is not a good idea to build houses
along the lines, where two of the earth's plates join together.Second, if you think
there may be an earthquake, it is better to build houses on rock not on sand.
Third, you must make the houses as strong as possible. Weak buildings will fall
down in an earthquake,but strong ones may stay up.

     Chemists have been studying why people cry. They say the body produces two kinds of tears. One kind cleans out
the eye if it gets dirt in it. But when people cry because of their feelings, these tears have poisonous chemicals in them. The body is getting rid of chemicals produced by strong feelings.
     In the United States men have heart diseases more often than women do. Doctors say heart diseases and some other diseases have something to do with the pressure. Perhaps men suffer more from these diseases because they do not
cry enough. And it is possible that as more and more women work outside their homes, they will also suffer from more
pressures. Then everyone will need to cry more.

A. how many kinds of tears the body makes

     Look at the pictures and read through the following passage, then choose the right answers.
     If we find a bird nest, we will have a good place of observing(觀察) and knowing about birds.
     Birds sit on eggs and take care of their baby birds from April to June. Because the baby birds are too
young to leave the nest, mothers often leave and come back to the nest during the time to look for food.
So it is good to observe birds. When we observe birds, we'd better hide(躲藏) ourselves in a close place
to the nest, and it's better to use binoculars(雙筒望遠(yuǎn)鏡).
     But how to make a bird nest? Picture 1 and Picture 2 are two kinds of bird nests. Picture 3 gives you
some other kinds of bird nests. They are very easy to make. If you want to make one, please follow these:
Making a nest: A good nest must be very fine, strong, thick and easy.
    a) Each nest must have six boards. Don't make the boards too slippery(光滑).
    b) Dig a small hole in the front of the nest as a door. The "door" is from 3cm to 5cm. So the bird can
fly in or out easily.
    c) Make sure the rainwater doesn't go into the nest.
    d) One piece of the boards should be easy to open.
    e) Please don't forget to color the nest.

     We know that many animals do not stay in one place. Birds, fish and other animals move from one
place to another place at a certain time. They move for different reasons: most of them move to find food
more easily, but others move to get away from places that are too crowded.
     When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in
warm water and move to cold water to feed. The most famous migration is probably the migration of fish,
which is called "salmon"(鮭魚).This fish is born in fresh water but it travels many miles to salt water. There
it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In
northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded.
They move down to the low land. Sometimes they move all the way to the seaside, and many of them are
killed when they fall into the sea.   
     Recently, scientists have studied the migration of a kind of lobster (龍蝦). Every year,when the season
of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean.
Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans
and animals move from one place to another place,but at other times we don't. Maybe living things just like
to travel.

     Bats are the only "flying animals" in the world. They can't see very well. We often hear "as blind as
a bat". Yet they have no trouble flying on the darkest nights and finding their ways round. How can
bats fly and see at night? They fly by radar(雷達(dá)).
     The bat's radar system(系統(tǒng)) works the same way as the radar in ships and planes. As a bat flies
through the air, it makes a sound. If the sound hits things, it will come back and the bat's ears will
receive the message. In this way the bat is able to know where the things are.
     Bats go out for food at night. In the daytime they hang in some dark places. Some people think
bats are bad animals. In fact they are useful animals.
