A kind of little cars may be seen in the streets in the future. People will like this kind of small cars better
than the big ones. The car is as small as a bike but it can carry two people in it. Everybody can drive it easily,
just like riding a bike. Even children and old people can drive them to schools or parks.
     If everyone drives such cars in the future, there will be less pollution in the air. There will be more space
for all the cars in cities, and there will also be more space for people to walk in the streets.
     The little cars of the future will cost less money to buy and to drive. These little cars can go only 65
kilometers an hour, so driving will be safer. The cars of the future will be fine for going around the city, but
they will not be useful for a long trip.
     This kind of cars can save a lot of gas (汽油). They will go 450 kilometers, then they have to stop for
more gas.
     They are nice cars, aren't they?

(     )1. Driving big cars can make the air dirtier.
(     )2. The little cars can make more space for other cars and people.
(     )3. These little cars will be useful for a long trip.
(     )4. This kind of cars can save much gas.
(     )5. Only children and old people can drive the little cars.

     Sometimes, people are not clear about what kind of food is healthy, and what kind of food may do
harm to our health. The USDA has prepared a food guide to help people learn about which kind of food
is the healthiest to eat. The food guide describes six main food groups: meat (like fish and chicken), dairy
(like milk and cheese), grains (like bread and rice), fruit, and vegetables. The last group is fats and sweets.
The USDA also suggests (建議) how much of each food group is healthy to eat daily. Though this guide
was prepared by the US government, it is very useful for people all over the world.
     As a result of years of study, we know that too much animal fat is bad for our health. For example,
Americans eat a lot of meat and only a small amount (量) of grains, fruit and vegetables. Because of the
way they eat, they have a high rate (率) of cancer (癌癥) and heart disease. In Japan, people eat large
amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease.
The Japanese live longer than anyone else in the world. However, when Japanese people move to the US,
the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers, ice creams
and other high-fat foods become popular in Japan, the rate of heart disease and cancer is going up there
as well. People are also eating more meat and dairy food in other countries, in which the disease rate is
going up along with the change of the way people eat. Doctors everywhere suggest people eat more
grains, fruit and vegetables and less meat and dairy food.
     Eating healthily is important for children as well as their parents. When parents have poor eating habits,
their children usually do, too. After all, children eat the same way as their parents. When parents eat
healthy food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors
suggest parents give their children healthier food such as fruit, vegetables and juice.
     Everyone wants to live a long, healthy life. We know that the food we eat affects (影響) us in different
ways. For example, doctors believe that fruit and vegetables can really protect people from many different
diseases. On the other hand, animal fat can cause (引起) diseases. We can change our eating habits now
and enjoy many years of healthy living.

       Hundreds of years ago, life was much harder than it is today. People didn't have modern machines.  
There was no modern medicine, either.      
       Life today has brought new problems.One of the biggest is pollution  (污染 ) . Water  pollution has
made our rivers and lakes dirty. It kills our fish and pollutes our drinking  water.  Noise pollution makes us talk louder and become angry more easily. Air pollution  is the most serious kind of pollution.  It's bad to
all living things in the world.       
       Cars,  planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it
is like a quilt over a city.  This kind of quilt is called smog (煙霧).       
       Many countries are making rules to fight pollution.  Factories must now clean their water before it is
thrown away. They mustn't blow dirty smoke into the air.      
       We need to do many other things. We can put waste things in the dustbin and not  throw it on the
ground.  We can go to work by bus or with our friends in the same car.  If  there are fewer people driving, there will be less pollution.

       Do you drink milk every day? Milk is good for health. It is one of the healthiest foods. But do
you know the best ways to drink milk? Here are some suggestions.

nuts, or shrimp (蝦).

     The earth is our home.  We must take care of it.  This means keeping the land, air and water clean.
     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
( 損害，傷害) 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 ( 毒藥), 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 ( 擺脫，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.
