Pollution is a "dirty" word. To pollute means to make things dirty. Pollution comes in many forms. We
see it, smell it and drink it. Pollution is beginning to do harm
( 损害，伤害) to our health, and even to our life.
Man has been polluting the earth from the time he first made his fire9 washed his clothes in the river
and threw his rubbish on the ground. Many years ago, the problem was not so serious because there
were not so many people. All the dirty things would soon be covered up. There was plenty of clean air,
land and water. When the land was used up or the river was dirty in a place, men moved to another
place. But this is no longer true. Man is now slowly polluting the whole world.
Talking about pollution, we once only meant air pollution. It is true that air pollution is still the most
dangerous now, but it is only one kind of pollution.
By using poison ( 毒药), we have polluted the land and killed the animals. By putting dirty water into
river and lakes, we have polluted our drinking water and killed the fish. The rise in population is part of
the problem. More people, more rubbish.
Where is this all to end? Are we turning the world into a big rubbish dump, or is there any hope that
we can get rid of ( 摆脱，除去) pollution? We are glad to say that the public has been warned of the
dangers of pollution and a large number of people are working hard to get rid of it.
( )1. Taking care of the earth means keeping the land, air and water clean.
( )2. Pollution is bad for our health, and even to our life.
( )3. The problem was not very serious because there were many people many years ago.
( )4. There are many kinds of pollution. Water pollution is the most dangerous.
( )5. Many people have realized the dangers of pollution and are working hard to get rid of it.

Do you feel a little sleepy after lunch? Well, that"s normal. Your body slows down then. What

we cannot work hard, how can we succeed and how can we be happy? Money can do many things and
make one enjoy the world in many ways, but it has no meaning to one who is not in good health.
A number of useful rules can do much to make good health, if we follow them.
Firstly, we must take food at regular times and never eat too much.
Secondly, keep our rooms airy (通风的). Fresh air is good for health, and also we must always
keep our bodies clean. Cleanliness (干净) keeps sickness away.
Thirdly, we must have enough sleep. Late to bed and late to rise will spoil and ruin (摧毁) our health.
And we must have exercises. Exercises make our muscles (肌肉) strong and protect (预防) ourselves
against illness.
Finally, there is one important thing to do: work. Making ourselves busy at work helps much in
keeping good health. Lazy people can never enjoy good health and can never succeed and be happy.
1. Having money but without good health can"t _______.
2. Rule One tells us that we should _______ and never eat too much.
3. Rule Two shows us that we should stay in the fresh air and _______
