Let us all raise a glass to AlphaGo and the advance of artificial intelligence. AlphaGo，
DeepMind’s Go-playing AI，just defeated the best Go-playing human，Lee Sedol. But as we drink to its success. we should also begin trying to understand what it means for the future.
The number of possible moves in a game of Go is so huge that. in order to win against a player like Lee. AlphaGo was designed to adopt a human—like style of gameplay by using a relatively recent development--deep learning. Deep learning uses large data sets，“machine learning”algorithms （计算程序） and deep neural networks to teach the AI how to perform a particular set of tasks. Rather than programming complex Go rules and strategies into AlphaGo，DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves. Then，AlphaGo played against itself, tirelessly learning from its own mistakes and improving its gameplay over time. The results speak for themselves.
Deep learning represents a shift in the relationship humans have with their technological creations. It results in AI that displays surprising and unpredictable behaviour. Commenting after his first loss，Lee described being shocked by an unconventional move he claimed no human would ever have made. Demis Hassabis. one of DeepMind's founders，echoed this comment：“We're very pleased that AlphaGo played some quite surprising and beautiful moves. ”
Unpredictability and surprises are—or can be—a good thing. They can indicate that a system is working well，perhaps better than the humans that came before it. Such is the case with AlphaGo. However，unpredictability also indicates a loss of human control. That Hassabis is surprised at his creation's behaviour suggests a lack of control in the design. And though some loss of control might be fine in the context of a game such as Go，it raises urgent questions elsewhere.
How much and what kind of control should we give up to AI machines? How should we design appropriate human control into AI that requires us to give up some of that very control? Is there some AI that we should just not develop if it means any loss of human control? How much of a say should corporations，governments，experts or citizens have in these matters? These important questions, and many others like them，have emerged in response，but remain unanswered. They require human，not human - like，solutions.
So as we drink to the milestone in AI, let's also drink to the understanding that the time to answer deeply human questions about deep learning and AI is now.
1.What contributes most to the unconventional move of AlphaGo in the game?
A. The capability of self-improvement.

2.A potential danger of Al is _____.
A. the loss of human control B. the friendly relationship

B. We should call on the government to solve these problems for us.
C. We should rely on ourselves and come up with effective solutions.
D. We should invent even more intelligent machines to solve everything.
4.What's the author’s attitude towards this remarkable advance in AI?
A. Supportive. B. Optimistic.
C. Doubtful. D. Cautious.
Dear Bobby Brune，
Children learn best when they're having fun. “Jungle Gym Jimmy”is an article for parents and children that teaches playground safety and shows how simply playing can promote good health and fitness. The tips are given through the funny voice of the“tour guide”on the playground，seven—year-old Jimmy. By listening to Jimmy, children learn how to use the equipment safely and how to get the most fun out of a day on the playground.
As a Kid Talk subscriber for the last seven years. I am very familiar with your publication, and feel this article would be a positive addition to the “I Can Do It” section of the magazine. The article is 2，114 words，and has been divided into categories in a way that holds children's interest. Being a mother of four children and using our home as a meeting place for most of the neighborhood，I've had the opportunity to test and confirm that the fun and easy “exercises” offered here are not only effective but are lots of fun for kids.
I've been writing children's stories and articles for several years, and have had many of my stories published in Kids Know Best，a small newspaper that the Cinder Primary School publishes each month. I'm also a founding member of the“Right On Baby”editorial group which publishes a monthly e—zine for parents with newborns, and I’m a contributing editor to “Write Now,” an online site that teaches creative writing.
Thank you for your time.
Sincerely,
Claudia Parker

Galaxy saw a man and a woman who communicated with the sign language at the train station when she was on the way home one evening. She noticed that the woman asked the man for the direction. He told her that he did not know. Galaxy decided to help them. She had learned the sign language when she served as a volunteer in the deaf and mute （聋哑） school.
