On a cold afternoon in winter, Robert was walking on the bridge. There was hardly any   1   on the river. Near the bridge, however, there was a small canoe(独木舟), with a boy in it. He was not    2   many clothes. He was going to walk when he heard a cry, “Help!” He looked down and saw the boy was in water and his canoe was far away.
Robert was a good   3 . Taking off his clothes, he jumped into the river. The cold water made him tremble(颤抖)all over. Soon he 4  the boy and started to swim towards the river bank. Just then he saw a motor boat under the bridge. There were some people on it, all 5 in his direction. Robert 6  to swim towards the boat.
“Help me,” he shouted   7  he got near the boat. He looked up into a row of faces. “Why?” he thought. “They look so    8 .” Silently they helped the boy into the boat. But they did not move to save Robert.
“Aren’t you going to help me  9  , too?” Robert asked.
“You!” said one of the men, who was standing next to a large camera, “Why, we were making a film and you spoiled (搅乱) the whole afternoon’s work! You can   10  in the water.”

Many people catch a cold in the spring time and / or fall.  It makes us wonder .if scientists can send a man to the moon, why they can't find a cure for the common cold. The answer is easy. There are exactly hundreds of kinds of cold viruses there. You never know which one you will get, so there isn't a cure for each one.
When a virus attacks your body, the body works hard to get rid of it. Blood rushes to your nose and brings congestion(充血)with it .You feel terrible because you can't breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells.  You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold.
Different people have different remedies（治疗法）for colds. In the United States and sane other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids.  Other people take medicine to stop the fever, congestion, and running nose.
There is one interesting thing to note - some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it .Bodies can do an amazing job on their own.  There is a joke, however, on taking medicine when you have a cold. It goes like this:
If it takes about one week to get over a cold if you don't take medicine,  but seven days to get over a cold you take medicine.
