In healthy human bodies, the immune system(免疫系统) protects them from diseases. But when one gets the AIDS virus(病毒) in his/her body it attacks and destroys the immune system, and the body then is helpless against diseases. And the patient will die of this or that disease.
But you don"t have to worry too much about being with the boy. The AIDS virus can"t live outside his body, and it can"t travel through the air. You don"t need to be afraid to touch him, either.
Children with AIDS need help from other children. They need to have friends to play with. Let"s try our best to do something for them.

Some day you may go to the moon. A tall rocket will take you into space. The rocket flies a long
way to a space station. You will stop there for a short time. Then a big spaceship will take you to the
moon.
About three days later,the ship slowly goes down and gets to the moon. You are now on the moon,
but you can not leave your spaceship. You must put on a space suit for the moon.It is very hot in the day
and very cold at night.If you don"t wear a space suit,you can"t live there. You jump out of the spaceship
and begin to walk.The moon is much smaller than the earth. The things on the moon are lighter than those
on the earth. You jump high in the air every time you take a step.
The moon moves slowly, so one day on the moon is as long as two weeks on the earth and one night
is just as long as two weeks on the earth. It never rains on the moon, and everything on the moon is dry.
There are no trees or other living things of any kind. There is nothing to do there. The earth is a far better
place to live on,but scientists are trying to make the best of the moon.

For example, when a bee has found some food, it goes back to its home. It is 1 for a bee to tell the
other bees where the food is by
speaking to 2 ,but it can do a little dancing. This tells the bees where the food is and how far it is.
Some animals show how they feel by making sounds. It is not difficult to tell if a dog is angry 3 it
barks (吠). Birds make several different sounds and each has its own meaning. Sometimes we humans
make sounds 4 . We make sounds like" Oh" or" Ouch" to show how we feel about something or
when we drop something on our feet. We humans have
languages. We have words. These words have the meaning of things, actions, feelings or ideas. We 5
give each other messages to tell other people 6 we think or how we feel. By writing down words, we
can remember what has happened or 7 messages to people far away.
Languages, like people, live and die. If a language isn"t used by people, it is called a dead language.
This language can not live and grow because 8 speaks it. Latin is an example of a dead language.
A living language, of course, is often spoken by people today.It grows and changes with time. New
words are created (创造) and some old words have 9 meanings. Some words, or their meanings,
may even die and only be found in the old books. English and Chinese are 10 examples of a living
language.

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.
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 plate
B. when one plate pulls another plate
C. when one plate jumps over another plate
D. when two plates don"t move

earthquake
C. must make the houses as strong as possible

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.

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.
