He flew far over the forest until he came to the towns of man． He went into a town and saw the burning things． He learned that it was called “fire”． He did not ask for a piece of it to take to the birds because there was so much food lying around man’s houses that he started eating and forgot what he came for．

互动课堂系列答案Why can’t some birds easily catch locusts（蝗虫）? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

Think of life as a game in which you are playing with five balls in the air. You name them work, family, health, friends and spirit (精神) and you keep all of them in the air. You will soon understand that work is a rubber ball. If you drop it, it will jump back.
But the other four balls, family, health, friends and spirit are made of glass. If you drop one of these, they will be broken. They will never be the same. You must understand that and try to have the balance in your life. How?
Don’t look down on your worth by comparing yourself with others. It is because we are different and each of us is special.
Don’t let other people set goals for you. Only you know what is best for yourself.
Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.
Don’t be afraid of difficulties. We learn how to be brave by taking chances.
Don’t shut love out of your life by saying it’s impossible. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly (紧紧地); the best way to keep love is to give it wings.
Don’t run through life so fast that you forget not only where you’ve been, but also where you are going.
Don’t be afraid to learn. Knowledge is a treasure (珍宝) you can always carry easily.
Don’t use time or words carelessly. You can’t get them back. Yesterday is history, tomorrow is a mystery (秘密), and today is a gift; that’s why we call it “the present”. Life is not a competition, but a trip, step by step.

The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.
There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.
