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?

56.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.

57.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

58.What does the underlined word “surpass” mean in the passage?

A. 象征 B.促进 C. 超越

59. 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

60. 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

Getting recognization(认可)from National Geographic, a famous US magazine, is the dream for many photographers. A lucky Chinese teenage photographer has made this dream come true just after his 14th birthday last year.

With his work Qiangtoucao (Weed on the Wall), Gong Zijie, a student from Changsha, Hunan, won the 2014 International Photography Contest for Kids in China’s competition last year. It was hosted by National Geog raphic Kids. Gong got the first place in the Wild Vacation part. His photo shows the shadow (影子) of a weed (野草) on the Palace Museum’s red walls. In world-famous photographer Li Sha obai’s words, “The picture is silent, but it’s also powerful.” How did Gong make it? “I just saw the weed and found it lonely and helpless,” said Gong.

Gong learned photography from his father, a photographer working for Hunan TV. Since the age of 4, he has been following his father to learn to take pictures.

Gong is a patient photographer. When he views something valuable, he can spend hours waiting for the perfect time for the picture. Compared with beautiful sights, the young photographer is paying more attention to social topic. In Gong’s pictures of Liuyang River, hundreds of dead fish show us the deadly results of pollution. He has made up his mind to document polluted rivers at least once every year to focus more people’s eyes on the environment.

“Now photography is not only a hobby, but also a duty for me,” said Gong.

61.Where did Gong Zijie take the photo named “Qiangtoucao”?

62. How did Li Shaobai like Gong’s photo in the passage?

63. What is Gong’s father?

64. How long has Gong learned photography?

65. Did Gong decide to document polluted rivers only once a year?
