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
