Artificial intelligence( 人工智能) is the ability of a computer or a machine. The computer or the machine with AI can think and learn. It is also a field of study that tries to make computers "smart". John McCarthy, a scientist, came up with the name "artificial intelligence " over 60 years ago. Many things such as learning and problem solving can be done by computers, though not in the same way as people do.

An unusual goal of AI research is to create special computer programs. They can learn, solve problems and think logically( 合乎逻辑地). At present, AI can successfully understand human speech, recognize( 识别) human faces, operate self-driving cars and compete in some game systems like playing chess. However, some people consider AI a danger to humans if it develops too quickly. A famous British scientist also was not for this kind of technology.

Math is the basic language of AI. If students are good at math, they will be more likely to become successful AI designers in the future. We need not only bright students but average(普通的) students. As for average students, if they get enough math skills, they can also become successful AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.

Scientists hope to create creative and emotional(有情感的) AI. The AI can possibly understand human feelings or create art. Many ways and tools have been tried to discover this wide and exciting field.

【题目】 Do you know why different animals or pests(昆虫) have their special colors? Their colors seem to be used mainly to protect themselves.

Some birds like eating locusts(蝗虫)but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of colors of crops. When crops are greenlocusts look green. But as the harvest time comeslocusts change to the same brown colors as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal lifeyou will find the main use of colors is to protect themselves. Bearslions and other animals move quietly through forests. They cannot be easily seen by hunters. This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid when they face danger. While the liquid spreads over(散开)their enemies cannot find them. And they immediately swim away. So they have lived up to now though they are not strong at all.

【题目】 I love Charles Barkley like a brother but we disagree from time to time. Here’s an example of what I mean: I disagree with what Charles says in his Nike commercial, the one in which he insist, “I am not a role model.” Charles, you can deny being a role model all you want, but we don’t choose to be role models, we are chosen. Our only choice is whether to be a good role model or a bad one.

I don’t think we can accept all the glory and the money that comes with being a famous athlete and not accept the responsibility of being a role model, of knowing that kids and even some adults are watching us and looking for us to set an example.

I love being a role model, and I try to be a positive one. That doesn’t mean I always succeed. I’m not saint (圣贤的). I make mistakes, and sometimes I do childish things.

But you don’t have to be perfect to be a good role model, and people shouldn’t expect perfection. If I were deciding whether a basketball player was a positive role model , I would want to know : Does he influence people’s lives in a positive way away from the court(球场)? How much has he given of himself, in time or in money, to help people who look up to him? Does he display the values ——like honesty and determination ——that are part of being a good person?

Kids have lots of other role models——teachers, movies stars, athletes, even other kids. As athletes , we can’t take the place of parents , but we can help reinforce(巩固)what they try to teach their kids .

Constantly being watched by the public can be hard to stand at times. I don’t think most people can imagine what it’s like to be watched that closely every minute of every day.

But the good things about being a role modeloutweighthe bad , It’s a great feeling to think you’re a small part of the reason that a kid decided to give school another try instead of dropping out or that a kid had the strength to walk away when someone offered him drugs . But one thing I would encourage parents to do is to remind their kids that no matter which athletes they look up to, there are no perfect human beings. That way, if the kid’s heroes should make mistakes, it won’t seem like the end of the world to them.
