Our sun is a star, and nine worlds (天体) move round it. Worlds like these are planets. But there are other stars, other suns, not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. but we haven’t been anymore. The stars are too far away from us. Stars give out light, but the planets don’t have any light of their own. So we can’t see them. They are too far, and too dark. Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this. Then we know that the star has a planet. For example, Barnard’s Star is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have known Bernard’s Star for many years, and now we are sure it has a planet.

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).
Close your eyes and imagine you are living in the next two centuries or more. You'll be living in a world filled with smart robots, which will be helping you to take care of your children, or your elderly parents in your home. You'll live much longer thanks to the medicine made by genetic (基因的) science. And mankind may be going farther in space than ever before-you will be living on the moon or Mars.
How should we view the changes that wait for us in the future? Should we be optimistic (乐观的)about the years ahead, or worried about what the future holds? Some scientists and experts are having a discussion about how technology, science and society will develop in the future.
"I'm looking forward to the day when more technology will come to my life," says John Searle, a professor at the University of California Berkeley Philosophy, "because I think further research in such areas as genetics, physics, chemistry and medicine will help us to overcome poverty, improve health, and make life longer."
Hugh Herr, at MIT's Biomechatronics Group, considers very powerful weapons as concern over the future. Another is the growing role of technology in our lives."Machines’ taking over what humans do is not a good thing," Herr says.
That is a similar concern shared by Daniela Cerqui, a social and cultural scientist. "I am afraid that the long-term future we are building will have no space left for human beings," says Cerqui. "The main values of our society are related to information that must progress as quickly as possible, and computers are much better than humans in these tasks ."
1. The second paragraph mainly tells us ________.
A. how science will develop in the future
B. how people will live in a modern society
C. what life would be like in the future
D. what computers will bring to our society
2.From Paragraph 4 we can infer that ___________.
A. John Searl is optimistic about the future
B. we should wait to see the changes in the future
C. John Searl worries much about what the future holds
D. further science research will be helpful for making life longer
3. The underlined word "That" in the last paragraph refers to________.
A. The poverty problem in the future
B. Machines’ taking over what humans do
C. The technology of weapons
D. The health problem of humans
4.The best title for the passage can be “___________”.
A. The Future--Full of Hope or Concern
B. Great Changes Will Take Place in the Future
C. The Relationship Between Technology and Humans
D. The Role of Robots and Computers in the Future

We often praise the world of science.
It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能，AI). This is an area where scientists are working on creating machines that think like humans.
However, one of the most famous scientists has a very dark warning for us about this type of technology.
“The development of full artificial intelligence could spell the end of the human race,” said Professor Stephen Hawking to the BBC.
Hawking is a well-known British physicist and author of bestselling science book A Brief History of Time. This warning came after commenting（评论）the technology he uses to speak with. As Hawking has got a serious disease called ALS, he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next.
This is a basic type of AI, which is very useful, yet Hawking fears the possibility of creating technology that can match or surpass human intelligence. And it’s easy to imagine how terrible things may be. Many TV shows and films show big, killer machines that are far cleverer than us. “Humans, who are limited（限制） by slow biological evolution (进化), couldn’t compete,” said Hawking.
But not every scientist is pessimistic (悲观的) about AI technology. “I believe we will be in control of the technology for a long time,” said Rollo Carpenter, creator of Cleverbot in the UK, which is a software program that remembers past conversations. “The advantages of it to solve many of the world problems will be realized.” In what direction do you think AI is heading? Should we be hopeful or fearful?
1.Which of the following is TRUE about AI?
A. It makes our lives easier.
B. The technology is not very popular now.
C. Scientists haven’t controlled the technology.
2.The writer took Hawking as an example to ______.
A. explain how AI has helped us
B. show AI has already become part of our life
C. suggest that AI might become dangerous for humans
3.What does the underlined word “surpass” mean in the passage?
A. 象征 B.促进 C. 超越
4.We can know from the last paragraph that _________.
A. Rollo agrees with Hawking
B. Rollo is a British creator
C. Rollo invented Cleverbot in the US
5.Which of the following can be a suitable title for this article?
A. AI: a friend or an enemy
B. The future of human beings
C. The fight between humans and AI
