are environments. The environment is everything around you. It can be living (有生命的), like a forest.
It can be non-living (无生命的), 1 a rock or a mountain.
No living thing can live alone. Every living thing depends (依赖于) on other things in its environment.
When something 2 , it affects (影响) something else. If a non-living; thing like water becomes 3 to
find, plants will be affected. If all plants 4 , the animals that eat plants will be affected.
Weather, such as temperature, wind and rain, can change an environment. 5 can change an
environment, too. Some things that people do cause no change or only a small change in the environment.
For example, people can walk through the forest and just travel around. They can cut down only a few
trees and 6 change the environment very much. On the other hand, some things that people do
cause 7 changes. Sometimes they can change a whole environment by cutting down a forest.
Not all changes are bad. If we cut down a forest to build houses or plant crops, this may not be bad.
But what would happen if we cut down all trees in all forests or if we didn"t 8 them and plant something
else?
It is clear that people are able to change an environment. This is why it is important to think about the

breakfast in one or two hours after they get up. It"s good to eat breakfast before nine o"clock.. Some
people don"t eat anything in the morning. Some are very busy. Others want to be thin. But both (两个
都) reasons are bad. It"s difficult to work or study well without breakfast, and it can"t help one get thin.
In fact, if one doesn"t eat breakfast, it may even make one fat. In the morning, you must eat some good
food. You can eat some eggs, some bread and drink some milk. You can eat some chicken as well. If
you get up late after nine o"clock, you still must eat breakfast. You can eat it in one or two hours after
you get up. | 1. When can people have breakfast?

smallest sign of it, they will fly away. Birds that cannot fly are often able to swim fast, or run quickly.
Some birds make themselves look bigger and more dangerous by fluffing (抖动) their feathers.
Another important protection for many birds is their colors. Their feathers often have colors that
match the things around their nests (巢). Some birds change colors with the seasons. In the winter they
are white to match the snow. In the summer they are brown to match the ground.
People sometimes kill birds without meaning to.When people cut down forests to build houses and
factories, they destroy the homes and food of birds. If the birds have nowhere else to go and nothing to
eat, they will die out.
Pollution may cause some birds to die. Birds that eat fish from polluted water get poison in their
bodies. Then they cannot lay healthy eggs. New birds can"t be born.
Now people protect birds by passing the laws to control hunting and pollution, by setting up some
special parks where all the birds are safe from hunters, and by teaching people to care about birds rather
than kill them. | How do birds protect themselves?
| By 1.______.
By fluffing their feathers.
By having colors that match the things around
their nests.

By teaching people to care about birds. | | 阅读理解。 | All of us know trees are useful to man in three very important ways: they give us wood and other
products, they give us shade, and the most important of all, they help to prevent droughts and floods.
In many parts of the world, however, people have not realized the importance of trees to us.
Two thousand years ago, a rich and powerful country cut down its trees to build its warships, with
which it gained itself an empire (帝国). It gained the empire, but without its trees, its soil became hard
and poor. When the empire fell into pieces, the home country found itself faced by floods and hunger.
Even when a government realizes the importance of forests, it is difficult for it to make villagers see
this. The villagers want wood to cook their food, and they can earn money by making things or selling
wood to the town people. They are usually too lazy or too careless to plant and look after new trees.
So unless the government does something to control and also to educate the people, the forests will
slowly disappear. | | 1. The most important service of trees is that _______. | A. they help people to get rich
B. they provide people with shade

B. to tell the story of the empire two thousand years ago
C. to call on people to do something to protect forests
D. to tell the people to plant as many trees as possible | | 阅读理解。 | Plants are very important. This is because plants can make food from air, water and sunlight.
Animals and man can"t make food from air, water and sunlight. Animals can get their food by eating
plants and other animals. Man gets his food by eating plants and animals, too. So animals and man
need plants in order to live. This is why there are so many plants around us.
Plants are classified (分类) into two kinds-flowering plants and non-flowering plants. Almost all
the trees around us are flowering plants. You can know some trees from their flowers and fruits.
Non-flowering plants do not grow flowers. You can"t see many non-flowering plants around you.
If you look at the plants around you carefully, you. will find that there are many kinds of plants. Some
plants are large and some are small. Most of them are green. Thanks to the plants around us, we can
live on the earth. | | 1. Which of the following is the most important to man according to the passage? | A. Fruits.
