Most animals are helped by people. They can’t live without us. But sometimes people have made the environment worse. For example, in some parts of the world the forests are being cut down.

The animals in the forests have become fewer and fewer. People hope to grow more food on the land, but the wind blows the earth away. Now forests become smaller and smaller, the soil becomes poorer and poorer. Now there are fewer animals and plants in the world. Insects (昆虫) are usually killed, but some plants need insects. Their seeds (种子) can’t spread without them. Birds eat insects, and without insects many kinds of birds will die.

There are hundreds and hundreds of plants and animals, and each plant is helped by another, so does each animal. If you hurt one, you will hurt another, then another. Scientists know this well. They don’t want people to break their environment.

1.It isn’t good for our environment to cut down forests.

2.Animals in the world are becoming fewer and fewer.

3.Animals and plants helped by each other.

4.After the wind blows, the earth becomes richer and richer.

5.This article tells us it is important to make our environment worse and worse.

    Plants and animals, including humans, need food and water to live on. These are from the natural resources
(资源) on Earth. To protect these resources, we need to keep the air clean and the water drinkable. We need
to keep the soil healthy. How do we do that?
* Protect the land
    The soil that covers fields and farms provides much of the food we eat. Human activities such as plowing (耕) fields, mining (采矿), and building highways can destroy (破坏) the land. Erosion happen when wind and
water carry away the soil. Soil erosion can turn rich farmland into a desert wasteland. So does this mean we
shouldn't build a highway or plow a field? Of course not. But it does mean we might think about Earth-friendly
ways of doing those things.
    Today farmers plow their fields in different ways to prevent erosion. They try to use less water for their
crops. They keep animals from eating the growing grass in just one area. Farmers also plant trees to prevent
erosion from happening.
* Save the Trees
    Another human activity that damages the land is deforestation (采伐森林). People take away a large number
of trees from a forest. Millions of square kilometers of forest disappear each year. When this happens, many
plants and animals lose their places to live. They may die out, or become very few. Scientists haven't even
discovered all the living things in the forest. We may be losing some without even knowing they are there.
Trees absorb (吸收) and use carbon dioxide (二氧化碳) when they make food. Environmentalists encourage
careful management of the forests. They ask people to replant trees after they cut down the forest. 
* Recycle, Reuse, Reduce
     People throw a piece of paper into the wastebasket after using it. The paper becomes trash. Where does
the trash go next? Much of our trash ends up in landfills (垃圾填埋地). They take up valuable land and
sometimes pollute the water, air, and land around them. More than a third of the trash in landfills is paper.
Recycling, reusing, and reducing what you throw away can cut down on the need for more landfills. In fact,
we can recycle about eighty percent of household trash.
1. What does the underlined word "erosion" mean?
[     ]
A. Plowing fields and mining.
B. Cutting down trees and farming.
C. Wind and rain carrying away soil.
D. Building highways on the farmland.
2. How do farmers prevent erosion now?
[     ]
A. They try to use more water for their crops.
B. They stop animals from eating the growing grass in just one area.
C. Farmers also plant flowers to prevent erosion from happening.
D. They move to another place.
3. Why do we need to save the trees?
[     ]
A. To discover more new trees every year.
B. To make more money.
C. To take away a large number of trees from the forest.
D. To keep good places for animals and plants to live in.
4. How much of the trash can we recycle?
[     ]
A. All the trash.
B. Very little.
C. One third.
D. Four fifths.
5. What's the purpose of the author writing the passage?
[     ]
A. To ask people to look for places to plant trees.
B. To tell people how to protect natural resources.
C. To show how the lands are destroyed by people.
D. To discuss ways of protecting animals and plants.

Elephants, tigers and many o__1__ animals were living in the thick forest. When people came to live in Hong Kong, the animals began to die out. Early farmers grew rice and r__2__ pigs and chickens in the valleys. They cut down the trees and burnt them. They needed fire to keep t__3__ warm in winter, to cook their food and to drive away the dangerous animals. Elephants quickly d___4__because there was not enough food for them. So did most of the wolves and tigers.

You might think that there are no longer any animals in Hong Kong e__5__ in the zoos, but there are still about 36 different animals living there. One of the most lovely of Hong Kong’s animals is the barking deer. There are beautiful little animals w__6__ a rich brown coat and a white patch under the tail. They look like deer but they are much smaller. They are less than two feet high. They make a noise rather like a dog barking. In Hong Kong the barking deer has only one r__7__enemy- men. People hunt these little animals though it is illegal(犯法的). There are now not many barking deer left. So it is important for people to protect these wild animals.
