阅读理解。　　Why do earthquakes happen? Scientists explain that the outside of the earth
is made of a number of different plates(极块). 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(毁坏) 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.1. Scientists explain that _____.A. the outside of the earth is made of a plate
B. the inside of the earth is made of different plates
C. the outside of the earth is made of lots of different plates
D. the earth is a plate2. An earthquake can be felt _____.A. when two plates push each other
B. when one plate pulls another plate
C. when one plate jumps over another plate
D. when two plates don"t move3. An earthquake shook San Francisco in the past because _____.A. San Francisco stands along between the Pacific Plate and the North American
Plate
B. San Francisco stands near the Pacific
C. San Francisco is near the sea
D. the city of San Francisco wasn"t built very well4. We can"t stop _____.A. earthquakes from destroying the whole of cities
B. earthquakes
C. building houses along the earthquake line
D. building weak houses at San Francisco5. We _____to make sure earthquakes don"t destroy the whole of cities.A. should build houses far from the earthquake line

阅读理解 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.1. Chemists are trying to understand _________.A. how many kinds of tears the body makes
B. why people cry

like soccer.

move the ball. Eleven men on the team try to stop the man who has the ball. If the man does not move the
ball ten yards, his team kicks the ball to the other team.

阅读理解。     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(雷达).
     The bat"s radar system(系统) 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.
