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 ofthe most famous scientists has a very dark warning for us about this type ofte chnology.

“The development of full artificial intelligence could lead to the end of the human race,” said Professor Stephen Hawking to the BBC.

    Hawking is a well-known British Physicist and writer of best selling science book A Brief History of Time. This warning came from 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 go beyond human intelligence. And it's easy to imagine how terrible things may be. Many TV shows and films display big, killer machines that arefar cleverer than us. “Humans, who are limited 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 remain in charge of（掌控) the technology. “ The potential(潜力) of itto solve many of the world problems will be realized.” In what direction do you think AI is going? Should we be hopeful or fearful?

    After a long day's study at school, you are very tired. So after school you go home to relax. When you get home, a robot greets you. He's happy to see you and helps you take your school things to your room. He listens to you talk about your school life and tells you a new joke. And he tells you to call your cousin and to say happy birthday. And then he helps you with your homework.

    This is your future, and the robot's name is NAO. NAO has a small body, big eyes and a large head. He can walk and dance. He listens and talks, and he even learns and thinks for himself. His creators(创造者) predict that the robot will be in people's homes before 2040.

    This $16,000 robot knows who you are. NAO can even express emotions(表达情感). He is a self-guided robot. A self-guided robot can sense(感觉), think and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, he can't act. Another robot can move and sense things, but he can't think for himself. These aren't self-guided robots. But NAO can do them all.

In America, there are chores for children of different ages. American people think it's important to tell children their duty in the family. They think that a 2-year-old child is never too young to do chores. If you have no ideas, use this list of age chores for your children.

A dance show called The Journey of a Legendary Landscape Painting《只此青绿》is on CCTV's Spring Festival Gala. It becomes popular very soon. The show gets the idea from the 900-year-old Chinese {#blank#}1{#/blank#}（paint） A Panorama of Rivers and Mountains《千里江山图》. The Song Dynasty painter Wang Ximeng made it{#blank#}2{#/blank#} the age of 18. The painting {#blank#}3{#/blank#}（show）a Chinese blue-green landscape(风景画)˗˗˗˗mountains between blue sky {#blank#}4{#/blank#}clean water. The dance shows the Chinese traditional beautiful paintings. The dancers each have a {#blank#}5{#/blank#}(differently) hairstyle. The clothes that they wear are green and blue. It also shows the colors{#blank#}6{#/blank#}the mountains and rivers. {#blank#}7{#/blank#} the dancers sway (摇摆) in {#blank#}8{#/blank#}(they) dresses, we seem to be looking at the moving mountains and rivers. Mountains and rivers are coming to 1ife more than 1,000 years later!Now more and more new shows are {#blank#}9{#/blank#} Chinese traditional culture(文化). We hope {#blank#}10{#/blank#}(many) young people will be interested in it.
