The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

   Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

   A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

   When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.

A long time ago, there lived a poor man whose real name has been forgotten. He was little and old and his face was wrinkled, and that was why his friends called him Mr. Vinegar. His wife was also little and old, and they lived in a little old cottage at the back of a little old field.

"John," said Mrs. Vinegar, "you must go to town and buy a cow. I will milk her and churn（搅拌） butter and we shall never want for anything."

"That is a good plan," said Mr. Vinegar, so he started off to town while his wife waited by the roadside.

Mr. Vinegar walked up and down the street of the town looking for a cow. After a time, a farmer came that way, leading one that was very pretty and fat.

"Oh, if I only had that cow," said Mr. Vinegar, "I would be the happiest man in the world!"

"She's a very good cow," said the farmer.

"Well," said Mr. Vinegar, "I'll give you these 50 gold pieces for her."

The farmer smiled and held out his hand for the money, "You may have her," he said, "I always like to oblige（施恩惠） , my friends!"

Mr. Vinegar took hold of the cow's halter and led her up and down the street. "I am the luckiest man in the world," he said, "for only see how all the people are looking at me and my cow!"

But at one end of the street, he met a man playing bagpipes（风笛） . He stopped and listened -- Tweedle Dee Tweedle Dee.

"Oh, that is the sweetest music I ever heard," he said, "and just see how all the children crowd around the man and give him pennies! If I only had those bagpipes, I would be the happiest man in the world!!"

"I'll sell them to you," said the piper.

"Will you? Well then, since I have no money, I will give you this cow for them."

"You may have them," answered the piper, "I always like to oblige a friend."

Mr. Vinegar took the bagpipes and the piper led the cow away.

"Now we will have some music," said Mr. Vinegar, but try as hard as he might, he could not play a tune. He could get nothing out of the bagpipes but "squeak, squeak". The children instead of giving him pennies laughed at him.

The day was chilly and in trying to play the pipes, his fingers grew very cold. He wished he had kept the cow.

He just started for home when he met a man who had warm gloves on his hands. "Oh, if I only had those pretty gloves," he said, "I would be the happiest man in the world."

"How much will you give for them?" asked the man.

"Oh, I have no money, but I will give you these bagpipes," answered Mr. Vinegar.

"Well," said the man, "you may have them for I always like to oblige a friend."

Mr. Vinegar gave him the bagpipes and drew the gloves on over his half frozen fingers. "How lucky I am," he said as he trudged（跋涉） homeward. His hands were soon quite warm, but the road was rough and the walking hard. He was very tired when he came to the foot of the steep hill. "How shall I ever get to the top?" he said. Just then he met a man who was walking the other way. He had a stick in his hand which he used as a cane to help him along.

"My friend," said Mr. Vinegar, "if only I had that stick of yours to help me up this hill, I would be the happiest man in the world!"

"How much will you give me for it?" asked the man.

"Well, I have no money, but I will give you this pair of warm gloves," said Mr. Vinegar.

"Well," said the man, "you may have it for I always like to oblige a friend."

Mr. Vinegar's hands were now quite warm, so he gave the gloves to the man and took the stout（结实的） stick to help him along. "How lucky I am!'' he said as he toiled upward.

At the top of the hill he stopped to rest. But as he was thinking of all his good luck that day, he heard someone calling his name. He looked up and saw only a green parrot sitting in a tree.

"Mr. Vinegar, Mr. Vinegar," it cried.

"What now?" said Mr. Vinegar.

"You're a dunce（傻瓜） , you're a dunce!'' answered the bird, "you went to seek your fortune and you found it, then you gave it for a cow, and the cow for some bagpipes, and the bagpipes for some gloves, and the gloves for a stick which you might of cut by the roadside. He He He, you're a dunce! You're a dunce!''

This made Mr. Vinegar very angry. He threw the stick at the bird with all his might. But the bird only answered, "You're a dunce! You're a dunce!" And the stick lodged in the tree where he could not get it again.

Mr. Vinegar went on slowly for he had many things to think about. His wife was standing by the roadside and as soon as she saw him, she cried out, "Where's the cow? Where's the cow?" "Well, I just don't know where the cow is," said Mr. Vinegar. And then he told her the whole story.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．

Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．

We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．

I don’t like my parents. They always tell me I should do this, and should not do that. It sometimes makes me angry,” said Liu Dan, a middle school student in Beijing. Do you have the same problem? Perhaps your parents had the same problem when they were your age long ago. Why does it seem that some parents are not so friendly in their children’s eyes?

One of the biggest things is when someone becomes a parent, he or she likes worrying things. They worry about everything about you from the time you were born. They do a lot for you, though something would make you angry, because they care about you and worry about you. They worry about your choice of friends, the food you eat, your work at school, how much sleep you get, etc. All these things are part of your life. They want you to grow up healthily and happily.

So how can you make things easier on yourself? It’s easier than you think. Just make sure your parents know what you’re doing. Get them to know your friends. Call them if you stay somewhere else later than usual. Say sorry to them when you make mistakes. Take responsibility for what you have done. Talk about your ideas with them. They may talk about theirs with you.

Most of all, try to think about why your parents do this or do that. They are still practicing being parents and need help you can give them. Someday, when you become a parent, they may be able to help you how to get on with your children.
