Do you know why different animals or pests have their special colors? Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts. but birds cannot easily catch them. Why? 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 the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you'll find the main use of coloring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all.

If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.

Anger(生氣) is a kind of feeling. Many things can make you angry. When your teacher gives you too much homework, when your team loses an important game, when a friend borrows your favorite thing and then breaks it, you may get really angry.
Usually, your body will tell you when you are angry. For example, you breathe faster, your face turns red, and you may want to break something or hit someone, but sometimes, you hide your anger. For example, you may hide it in your heart. The problem is that if you do this, you may get a headache or your stomach may hurt.
In fact, it’s not good to hide your anger, and it’s normal for you to get angry sometimes. But anger must be let out in the right way, without hurting others or yourself.
When you get angry, you can talk about it with other people. It’s helpful to talk about your anger with an adult, such as parents, a teacher, etc. When you talk about anger, those bad feelings can start to go away. Here are some other things you can do when you start to feel angry: talk to a good friend; count from 1 to 100; give someone a hug(擁抱); go for a bike ride; think about good things, etc.

“Depend on yourself” is what nature says to every man. Parents can help you. Teachers can help you. Others still can help you. But all these people only help you to help yourself.
There have been many great men in history. Many of them were very poor when they were young, and had no uncles, aunts, or friends to help them. Schools were few and not very good. They could not depend on them for education. They tried their best to learn something and never gave up till they became well-known. One of the most famous teachers in England used to tell his pupils, “I cannot make worthy men of you, but I can help you make men of yourselves.”
Some young men don’t try their best to make themselves valuable to the human beings. If they see their weak points and change their ways, they can be successful. They are nothing now, and will be nothing as long as(只要) they live, unless they accept the advice of their parents and teachers, and depend on themselves.
小題1:Why did many men succeed?

Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat.
Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag.
Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cakes often come in bite-size pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the spaceship. The water is put in the special gun. The astronaut shoots the water into his mouth.
小題1:Some food carried in the closed bags by astronauts is ________.

Walk to school every day? That will work, but not if you like sleep in. If you like bad smells and crowding(擁擠), the bus might be your best Choice. But why not a bicycle? A bicycle will get you there faster than your feet and will save your money.
This is why you see more bicycles than any other kind of transportation in China, about 500 million of them. That’s close to one for every two people in the whole country. But if you survey your class at school, you may will find a higher rate(比率).
Bicycles became popular because they are fun for people and at the same time help develop a strong body. No vehicle is better than a bicycle for enjoying an autumn weekend outside the city with parents or friends. You can travel on small, quiet paths. You also can park your bicycle beside the path wherever you want to stop to admire the beauty.
Cycling every day helps people build with city healthier hearts and stronger muscles(肌肉). Scientists say a 30-minute ride every day can help you lose weight.
Today, bicycles also are popular with city planners. They see bicycles as a good way to reduce heavy traffic. Unlike buses, bicycles produce no exhaust(尾氣) and don’t burn energy. Many countries are encouraging more daily use of bicycles.
