假设你是红星中学学生李华， 这学期你加入了学校的英语阅读沙龙并收获颇丰。 最近你收到负责沙龙活动的外教 Jim 的群发邮件，请阅读该邮件， 并给他回复。 回信需包括你收到邮件的感受，以及你对外教所提问题的建议。
Dear members,
I am afraid I won’t be able to run our reading club next semester, as I was asked to teach another class on Thursday afternoon—the same time our club usually meets. Besides, it seems we do not have enough people joining this club, although some students did ask about registering. If you really want to keep this club, can you think of any suggestions? Please write to me soon.
Yours,
Jim

AlphaZero--an Updated Model of AI
Soon after Garry Kasparov, the former world chess champion, lost his rematch against IBM’s Deep Blue in 1997, the short window of human-machine chess competition slammed shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue. However, as people see with the new AlphaZero system, machine dominance has not ended the historical role of chess as a laboratory of cognition.
Much as airplanes don’t flap their wings like birds, machines don’t produce chess moves like humans do. Based on a generic algorithm (算法), AlphaZero incorporates deep learning and other AI techniques like Monte Carlo tree search to play against itself to develop its own chess knowledge. Unlike the traditional program Stockfish, which employs many preset evaluation functions as well as opening and endgame moves, AlphaZero starts out knowing only the rules of chess, with no preset human strategies. In a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating the relative values of the pieces. It quickly becomes strong enough to win 28, draw 72, and lose none in a victory over Stockfish. Since AlphaZero can program itself, this superior understanding allows it to outclass the world’s top traditional program despite calculating far fewer positions per second. It’s the typical example of the cliché, “work smarter, not harder”.
AlphaZero shows that machines can be the experts, not merely expert tools. Explainability is still an issue—it’s not going to put chess coaches out of business just yet. But the knowledge it produces is information humans can learn from. AlphaZero is surpassing humans in a profound and useful way, and researchers are working on transferring the knowledge acquired from AlphaZero to other fields.
Machine learning systems aren’t perfect. Even though great progresses have been achieved, AI algorithms are still struggling on open problems such as computer vision, natural language understanding... There will be cases where an AI will fail to detect exceptions to its rules. Therefore, as Kasparov writes, “We must work together to combine our strengths. I know better than most people what it’s like to compete against a machine. Instead of raging against them, it’s better if we’re all on the same side.”
