We human beings haven’t been good friends to animals. For thousands of years, we have been polluting the environment, making it hard for animals to live on the planet. We have been killing animals for their fur, feathers or meat, or simply because they are dangerous. As a result, many kinds of animals have disappeared forever. Hundreds more are on the endangered list today.
Should we care about animals? Of course we should. If animals of a certain kind all disappear, they will never come back again. Animals are more than just resources of things we need. Every kind of animal has its place in the balance of nature. Destroying any kind of animal can lead to many problems. For example, when farmers killed large numbers of hawks, the corn and grain that the farmers stored were destroyed by rats and mice. Why? Because hawks eat rats and mice. With less and less hawks to keep down their numbers, rats and mice multiplied quickly. And if people kill too many birds, more and more insects will eat the crops.
Luckily, we’ve realized that we shouldn’t kill animals any more. And people are working hard to save those animals that would disappear soon. The government also passed laws to protect the endangered animals. In fact, quite a few countries have passed such laws. These laws forbid the killing of any kind of animal on the endangered list. We should try our best to protect and save the endangered animals.
1.The text calls on us to__________.

2.Why do people kill animals?
A.Animals cause many serious problems.
B.They kill animals for something they need.
C.Animals destroy their natural resources.

3.The example that farmers killed hawks shows that__________.

Both humans and animals have enemies. It is easy for us to know the difference between our friends and our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who mean a threat and those who do not. In Kenya, researchers find that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men hunt animals and thus mean a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.
In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants noticed the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they noticed the smells of either clean clothing or clothing worn by a Kamba man.
Clothing color also plays a role. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted angrily toward the red clothing.
The researchers believe that the elephants’ emotional reactions are due to their different senses of smell and sight. Smelling a possible danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.
1.The author wrote the text in order to tell us that elephants are _____.
A. dangerous B. friendly C. clever D. naughty
2.How did the elephants react to smells in the study?
A. They attacked a man with the smell of new clothing.
B. They needed time to relax when smelling something unfamiliar.
C. They became anxious when they smelled Kamba-scented clothing.
D. They were frightened and ran away when they smelled their enemies.
3.What can be inferred about the elephants’ behavior from this text?
A. Elephants can tell enemies from friends.
B. Elephants have a sharper sense of smell than sight.
C. Elephants are more intelligent than other animals.
D. Elephants tend to attack rather than escape when in danger.
4.In which section of a magazine will the text be most probably found?
A. Business. B. Fashion. C. Nature. D. News.
