Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims (声称) as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your house is your territory where only your family and friends are welcome.If a stranger should enter your territory and threaten you, you
might shout. Probably this would be enough to frighten him away.
If so, you have actually frightened the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting (筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
1.Some scientists believe that most of the time bird’s singing is actually _______.
A. an expression of happiness B. a way of warning
C. an expression of anger D. a way of greeting
2.What is a bird’s “territory”?

Have you ever thought of such questions as “Why do I have to study math?”or “I am not interested in history at all. My dream is to be an actor. Should I give up history?”
Maybe you are right. After you leave school, it’s not necessary for you to understand everything. But please remember that at school, besides getting knowledge, you should pay attention to some other important things.
First, try to find what you are most interested in. At school, you study many subjects. Try to find what you like and what you don’t like. This may be helpful to you in the future.
Second, maybe you don’t like math and you want to drop it. But the logical thinking ability from math can help you solve some problems. At school, you should practice your brain by thinking.
Third, you should believe in yourself. Maybe you learn French at school, but you don’t need to speak French at all. But learning French can prove that you have the ability of learning languages. Suppose you go to France one day and find a good job well. At school I learned French well, and now I must be able to learn German. But if you have no confidence, what will happen?
Try to challenge yourself as often as possible. I think many of us like playing computer games. When we fail in a game, we always want to try it again. Why? Because it is hard for us to get the highest mark. If we want to challenge ourselves, we must face more difficult things and make greater progress.
1.At school you should______________ .
A. stop learning the subjects you don’t like
B. both get knowledge and improve your ability
C. pay more attention to math and French
D. learn French instead of English
2.Math can improve one’s_______________.
A. logical thinking ability B. skills in computer
C. interest in other subjects D. ability of finding a job
3.Which of the following is TRUE?
A. You will use everything you learn at school in your future job.
B. It’s not necessary to know what you like at school.
C. Everything you learn at school has an influence on you.
D. Logical thinking ability is the most important ability.
4.Learning French can help us ___________ .
A. have confidence in learning languages B. go to France
C. get a good result in the exam D. make greater progress

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.
1.It is not easy for birds to catch locusts because____________.
