WHEN ARE YOU AN ADULT?
　　Many countries have ceremonies to celebrate their young people becoming adults. However, some countries do not. Instead, young people think of themselves as adults when they can do “adults” things. But when do you become an adult in the U.S.A.? Let’s look at what some American teenagers say.
　　Sam: I think you are an adult at 18. That’s when you can vote. You can help to choose who runs the state and the whole country. That’s grown up! My grandfather couldn’t vote until he was 21. They only change it to 18 in 1971. I guess they think we are more responsible at 18 now.
　　Jenny: I think it’s hard to choose. I get to drive a car at 16, don’t I? That’s a serious responsibility. When you have a driver’s license you show it to people to prove your age for all kinds of things. So that must be the age when you change from a young person to an adult. Because you have to prove you are that age and not a kid.
　　Suzie: I think there is something crazy about American laws about when young people can do things. So I can vote at 18 and drive at 16. So you would think that 18 is grown up, even if 16 isn’t. But then I can’t drink alcohol until I’m 21! If I’m an adult at 21, how can people stop me buying a can of beer in a shop?
　　vote: 选举
　　43. Which of the following is TRUE?
　　A. You can’t vote until 21.
　　B. You can drive a car at 18.
　　C. You can’t drink until 16.
　　D. You can buy beers before 21.

　　44. Sam thinks “grown up” means __________.
　　A. you can help to choose the president and governors
　　B. you can drink alcohol
　　C. you are responsible for all things you do
　　D. you can drive a car

　　Firstly, what were dinosaurs?

　　Dinosaurs lived on Earth a long time age; some dinosaurs were huge and had long tails-they were bigger than a whole family of elephants. Others were very small-they were about the size of a chicken. Not all dinosaurs ate meat. Some just ate plants. Not all of them were dangerous. Some were harmless.

　　When did they live on earth?

　　Dinosaurs lived on Earth for about 135 million years. Man has lived here for only 35,000 years About 65 million years ago, however, all the dinosaurs died in a very short period of time. Nobody knows why it happened suddenly.

　　How do we know about dinosaurs?

　　Scientists study dinosaur bones and eggs to get information. They discover how dinosaurs lived, what they looked like, where they lived and what they ate. Scientists now believe that dinosaurs were very colorful animals.

　　Were they clever animals?

　　In the past, scientists thought that dinosaurs were slow and stupid. We now know that many dinosaurs were fast and powerful. Some were not only fast, but clever too. They used the long claws on their feet to kill their food. Other dinosaurs were probably very stupid. One very large dinosaur had a brain the size of a peanut!

　　Do you think they could ever live on Earth again?

　　In the Hollywood film Jurassic Park, a scientist brings dinosaurs back to life from an old egg. Scientists in China recently found some dinosaur eggs similar to the one in the film. Could they bring dinosaurs back to life? It is unlikely, but in science, anything seems possible!
