It is easy for us to tell our friends from our enemies. But can other animals do the same Elephants can! They can use their eyes and nosesto tell the difference between dangerous people and friendly people. In Kenya, scientists found that elephants knew the different clothes of Maasai and Kamba people.Maasai men often kill animals for food, so they are dangerous to elephants. Kamba men are farmers and not a danger to elephants.
Last year, some animal scientists did an experiment. They found that elephants reacted(反应)differently to smell and color.
First , elephants were shown clothes of either a Maasai or a Kamba man. When the elephants smelt the clothes worn by a Maasai man, they moved away fast. When they smelt the clothes worn by Kamba men, they relaxed.
Then, the same elephants were shown red clothes. They got angry, because red is often worn by Maasai men. Instead of running away, the elephants rushed angrily to the red clothes.Why If an elephant smells a danger, he thinks that the danger is close and the best thing to do is to run away and hide. If he sees a danger, he thinks the risk(危险)is low.So the elephant seems a little braver and gets ready to fight.
( )1.Elephants think Kamba men are safe because they .
A.like the smell of Kamba men
B.know Kamba men don't kill animals
C.often get some food from Kamba men
D.like the color of Kamba men's clothes
( )2. When he finds himself in danger, an elephant .

There are all kinds of animals on our planet. Some are sweet, some are not; some are small, some are tall. Here are four pictures of some of the funniest, friendliest faces. But remember, although they look nice, it doesn't mean they are always friendly.
Not all dogs are cute, but most of them are pretty friendly. When you come near an unfamiliar dog, remember to hold out your hand, so he can smell you and see that you mean no harm.
Cows love to eat grass, and they eat quite a lot! You needn't be afraid of this quiet farm animal. But don't run at a cow in a field or touch one, unless you are told by an adult it's OK.
Horses are big, beautiful animals, but they can be surprised easily. A horse might jump up if she hears a loud noise, or kick her legs if you come near to suddenly. All horses, like humans, are different.
Chimpanzees make funny faces and put on a real show at the zoo, but believe it or not, they can be very dangerous. And they are strong---too much stronger than humans---so you should never make a chimp mad!
( )5.We can learn from the passage that .
A. cows are quiet B. all dogs are cute
C. horses never kick D. Chimpanzees are not dangerous
( )6. According to the passage you should when you come near an unfamiliar dog.
A. feed him something B. shout at him
C. Touch his head D. hold out your hand
( )7. The author wants to tell us that
A. some animals are sweet, but they are small.

C. some animals are funny, but they are not beautiful.
D. some animals look nice, but they are not always friendly.

In nature, you may see many insects (昆虫）and animals of different colors. Have you ever wondered why
Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears,tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤）in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.
