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.

“Cool” is a word with many meanings. It means a little cold at first. As time changes, the word gets many different meanings. We can use “cool” when we talk about something wonderful or somebody looking smart. For example. When you see a beautiful and expensive car in the street, you can say, “It is cool.” You may think the famous film star Keanu Reeves is cool. You can also use the word to mean something new and surprising. Here is an example. One day a teacher took the students to a farm and then asked them to write something about the visit. One of her students just wrote, “The farm is so cool.” Because he thought “ cool” was the best word to show what he saw and felt. It also shows some people don’t have enough words. Without “cool”, they seem to have no other words to use. Can you think of any other words like “cool: with so many meanings? If you can they are also very “cool”.
