Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.

When I was seven years old, my family made me an ant farm. First, we put clean sand in a thin glass box. Then we waited for the ants to arrive.
After the ants were in the glass farm, they started to make tunnels（地道）. I was amazed that each one knew exactly what to do. Each had its own job.
On the fifth day a tragedy（悲剧）happened. I put my face so close to the glass farm that I knocked it over. All the tunnels fell down. Although the ants remained alive after their earthquake, one by one they began to die. I was scared as I watched them give up building their tunnels to carry the bodies to a corner of the farm.
My mother said that the ants were dying of sadness. They simply could not stand that their tunnels were gone.
Although much time has passed, I still think of that ant farm. Mom had hoped it would teach me about the natural world, but it taught me much more.
Over the years, I came to realize the importance of teamwork. Working together, the ants were able to make an amazing world for themselves. I also learned that they should be admired（钦佩）for their hard work.
But there was an even larger lesson that I did not realize until recently: Adversity（逆境）is a natural part of life, and must be accepted. Unlike the ants, we cannot give up when we are sad. We have to realize that if a tunnel is gone, we must build another.
Giving up, I say, is not a good choice.
