Most animals protect(保護(hù)) their young until they are old enough to take care of themselves. A fish that swims in the rivers of South America protects its young in a very strange way. This fish, a kind of catfish, uses its mouth to keep its babies from danger(危險(xiǎn)).
When this catfish lays(產(chǎn)卵) its eggs, it carries them in its mouth. From what we know, it does not eat during this time. After the eggs hatch(孵化), the fish swims with its young to protect them. It opens its mouth when danger appears(出現(xiàn)), and the tiny fish swim inside. They swim out only when it’s safe again.
These catfish may have a peculiar way to protect their young, but it seems(好像) to work.

It is said that another acre of the world’s forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The  forest becomes a desert. Then more land will be needed, and more trees will be cut down.
When the forest is destroyed, it isn’t only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.
Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.
【小題1】People cut down large areas of trees in order to _________.
A．grow cropsB．keep animalsC．build housesD．get land and wood
【小題2】 In most places, __________after trees are cut down.
A．new trees can grow betterB．forests will become deserts
C．most animals can live thereD．people build new house there
【小題3】 According to the passage, we should  _________________ to protect the forest.

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (遷徙) is probably the migration of fish, which is called “salmon”(蛙魚(yú)). This fish is born in fresh(淡的) water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster (龍蝦). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.
【小題1】 Most animals move from one place to another at a certain time to _______.

A．enjoy warmer weather

D．get away from crowded places
【小題2】 The underlined word “There” in the second passage means “___________”.

A．It’s a safe traveling way.
B．The weather is bad.
C．It is still unknown to us.
D．They just don’t want not to be too crowded.
【小題4】 The passage is mainly about ________________.”
A．the migration of animals
