听力原文： Many animals recognise their food because they see it. So do humans. When you

see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses, to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given other choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season. Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life. Questions 22 to 25 are based on the passage you have just heard. 22. What can we infer about humans and animals from the passage？ 23. Which animal eats only one type of food？ 24. When do certain animals change their choice of food？ 25. What can we learn from the passage？23．

A．The white butterfly.

B．The small bird.

C．The bear.

D．The fox.

听力原文： Man has a big brain. He can think and speak. Scientists used to think that men are different from animals because they can think and learn. They now know that animals can learn —dogs, rats, birds —and worms —can learn. So scientists are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or angry, or unhappy. Apes are our nearest cousins. They can understand some things more quickly than human beings, and one or two have learned a few words. But they are still different from us. They cannot join words and make sentences. They cannot think like us because they have no language. They can never think about the past or the future.Language is a wonderful thing. Man has been able to develop civilization because he has language. Every child can speak his own language very well when he is four or five —but no animal learns to speak. How do children learn？ Scientists do not really know. What happens when we speak？ Scientists do not know. They only know that man can speak because he has a big brain.

(34)

A．Because he has a big brain.

B．Because he learns to speak.

C．Because he develops civilization.

D．Because he knows many words.

Why do Westerners love their pets so much, almost as if they were their children? I su

Why do Westerners love their pets so much, almost as if they were their children？ I suppose one reason is that for more than one hundred years many children's books in England and in America were animal stories.By this we mean stories that gave the animals human names, human voices, human emotions, and even faces that look almost human.Many of these stories taught a moral lesson, like honesty or kindness or hard work.My mother read animal stories to me as a child, and my wife and I read some of the same animal stories to my boys when they were small, and now they read animal stories to their children.Some are the same stories about dogs and cats and rabbits and horses.So children in America grow up with good feelings toward animals. Many families would like to have a purebred dog or cat, that is an animal whose parents come from a single kind of animal.But purebred animals are expensive.And those that are registered with a special dog or cat club are even more expensive since there is a written record of their ancestors for many generations.What often happens is that a family's first pet will come from some friend whose pet has had babies.Or they may get a pet from an animal shelter.Every city and many smaller towns have a humane society which cares for animals that are found and for animals which people no longer want.They try to find the owner of lost pets and to find homes for the others.Over the years my wife and I and our children have gotten some very nice dogs for our family from animal shelters, usually at no cost.

But some families do not want a house dog or a house cat.They want an outside dog or cat.So the animal stays outsides the house most of the time.Special dog houses are made for such dogs to use, especially at night in the colder parts of North America.

1.Why do Western people love their pets so much？ ()

A.Because their children don't have many friends.

B.Because they have leisure time and enough money.

C.Because they are influenced by animal stories.

D.Because they regard pets as their children.

2.Since they have heard a lot of animal stories, American children tend to () .

A.love animals when they grow up

B.treat animals rudely

C.live with animals

D.dislike animals

3.A purebred dog refers to a dog()

A.which is brought up by one family

B.whose parents come from the same area

C.whose parents belong to the single kind of dog

D.which is bred in a pure house

4.How do most Americans get their first pet？ ()

A.They buy it from a pet shop

B.They pick up one from the street

C.They always get one from the animal shelter

5.Not all pets stay with their masters in the house all the time for().

A.it's good for them to stay outside

B.people think they are dirty

C.Some people don't want a house dog or a house cat

D.they don't like to stay in their masters' house

B Most of the animals have little connection with animals of a different kind, unless the

Most of the animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however. two kinds of animals.come together in a partnership which is good for both of them. You may see some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites(寄生虫)on sheep. The sheep allow the birds to do so because they move the cause of discomfort. So although they can live without each other, they do better together.

Sometimes an animal has a plant partner. The relationship develops until the two partners cannot live without each other. This is so in the corals(珊瑚) of the sea. In their skins there are tiny plants which act as "dustmen" , taking some of the waste products from the corals and giving in return oxygen(氧气) which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.

60. Some birds like to sit on a sheep because_____

[ A] they can eat its parasites

[ B ] they enjoy traveling with the sheep

[C] they depend on the sheep for existence

[ D] they find the position most comfortable

The deserts of the world are not all covered with sand. Many of them have surfaces of rock

or clay or small stones. They are not flat, either. They often have high hills and deep valleys. There is some plants' life in many parts of the desert. There is little rain in the desert, but it does fall often enough for most plants.

The deserts of the world are not uninhabited (not lived by people). People also live outside oases(绿洲), but these people are not farmers. They have camels, goats, donkeys, sheep, etc. These animals can live on the desert plants and do not need much water.

The people of the desert have to move constantly from place to place, or they must always look for grass or desert plants for their animals. They usually live in tents. When there is no more food for their animals, they fold up their tents, put them on their camels and donkeys, and move to another place. In good years, when there is enough food for their animals, they trade their skins and their goats and camel hairs with the people of oases for wheat and fruit. But in bad years, when there is not enough food for their animals, the people of the desert would attack the oases people. But they are also hospitable, no man in the desert would ever refuse to give a stranger food and water.

In the desert______.

A．it rains in spring only

B．there is some rain, but far from enough

C．it rains for a short time every month

D．the rainfall is just enough for the plants

听力原文： Why do people want to save the Whales？ There are two important reasons. One reason is that whales help to keep a balance between plants and animals. People have disturbed this balance. People get rid of their wastes by throwing them into the oceans and seas. People's sewage and garbage increase the salt in ocean and sea water. The increased salt helps some plants and some very small animals to grow. These plants and animals can be harmful to fish. Whales eat enormous amount of plants and animals that grow in very salty water. Therefore, whales are very important because they keep the ocean environment clean enough for fish. In addition, because fish provide necessary food for many people, people need whales, and many people want to save them.

(23)

A．Because whales keep a balance between plants and animals on land.

B．Because whales eat a lot of fish.

C．Because whales eat large amounts of garbage.

D．Because whales keep oceans clean for fish, and people need fish.

听力原文： What is cloning？ Cloning is the creation of cells or whole animals using DNA fro

m a single "parent", bypassing the normal reproductive process. The clone has the same DNA as the parent.

The most common process takes DNA from one cell and puts it in a hollowed-out egg. Chemicals and electricity are then used to encourage the new DNA to fuse with the egg and develop into an embryo. This technique is called nuclear transfer.

The first cloned animal in human history was a sheep called Dolly. It was very important because it was the first mammal to be cloned using DNA taken from an adult cell. Previously, animals had only been cloned using embryo cells, which already have the potential to become complete embryos in their own right. The big breakthrough with Dolly was that a clone was made from an ordinary, adult cell.

When it comes to the question of whether cloned animals are normal and healthy, the answer is YES. Dolly is, but scientists do not yet know whether this is the exception or the rule. Some early evidence suggests that clones may have health problems and that they may age prematurely.

With the birth of Dolly, many people are worried that a human clone may be born soon. It's possible in theory. But the technology of reproductive cloning is still in its very early stages and there is much that scientists do not understand. What's more, human cloning is already banned by law in the United Kingdom. The former President of the United States, Bill Clinton, proposed banning research into producing human clones in the U. S. for five years. Some measures have also been taken to establish international agreements banning live human clones.

What has cloning bypassed？

A．The nuclear transfer.

B．The process of taking DNA

C．The normal reproductive process.

D．The creation of cells.
