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.

A. The capability of self-improvement.

2.A potential danger of Al is _____.

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?

At the end of August this year I moved from London，UK，to a small town in Quebec， Canada，called Matane to work as an English language assistant.Patience is a word that has appeared in many forms over the past two months.
I don't see myself as being the most patient person in the world but there was something that struck me on my first week of work.I had just finished a session with two students and just as they were leaving the classroom，one of the students turned back and said，"Thank you for your patience." That was an early reminder of the importance of being patient as a teacher. It also made me reflect on the language teachers that I have had over the years， ones that demonstrated a high level of patience and understanding that has shaped my language learning path. Moreover， it helped me to realize the importance of demonstrating patience in the classroom as it can be the difference between building someone's confidence in a language or breaking down their confidence entirely.
Living my life constantly in French is not easy but the people of Quebec are very patient.They repeat things several times and they are more than happy to wait while I find the correct words to express myself and find the correct word order.It's a learning process but with the patience of others， the process is slightly less nervous.At the end of the day， making mistakes shows you are trying and I think that is greatly appreciated by Quebecers.
When I first arrived in Matane I kept getting headaches from having to concentrate all the time due to the language and even overhearing other people's conversations was hard work! I had to keep reminding myself that it would take time， and two months later the headaches are a distant memory and my ears have become more tuned to their accent.The key is to be patient with yourself.
