He finds the book a little difficult but very interesting. The word AI is very popular now, and he enjoys reading it very much. He has learned a new idea about AI from the book.When people ask AI a question, it answers the question in a very short time. So, people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen. Actually, AI only uses a lot of information to get the best answer. So, when it has more information, the answer will be much closer to the perfect one. AI technologies will be cleverer tools for human beings to use. This book also says almost half of our jobs will be done by AI technologies in the near future. People will soon find more AI technologies in our lives, such as checking the tickets, the price, people’s faces and fingers.So, we believe that we will have much happier lives with these AI technologies around us.21.

答案一、1. C 2. D 3. A4. B 点拨：用词义辨析法。句意为“——昨晚一个机器人为我们提供晚餐。你不觉得我们生活在一个令人惊奇的时代吗? ——我完全同意。科技让我们的生活更容易、更快乐”。information 意为“信息”; technology 意为“科技”; discovery 意为“发现”; competition 意为“竞争”; 根据robot 可知, 机器人是一种新科技。5. D 6. D 7. A 8. D 9. A10. D 点拨：用语法判断法。句意为“四月份我看到过Julia, 自那以后我再没见过她”。since then 是现在完成时的时间状语, 所以需要用现在完成时。故选D。二、 11. B 点拨：boring 和tiring 用来修饰物, 排除选项A 和D; 根据后一句中“去看电影”可知不是“累的”, 排除选项C。故选B。12. A 点拨：根据后半句“我没有看很多海盗电影”可知, “我”不是一个海盗迷。A 项符合句意。13. C 点拨：句意为“我认为这部电影是我所看过的电影里面最好的”。强调过去做过的事对现在的影响, 用现在完成时。故选C。14. D 点拨：句意为“虽然他们是海盗, 但他们并不可怕”。表示“虽然……但是……”, though 与but 不能连用。故选D。15. B 点拨：play the role of 是固定短语, 意为“扮演……的角色”。故选B。16. C 点拨：短文后面还提到了其他演员, 在很多演员中比较, 用最高级; 此段最后一句还说“其他演员演得也很好。”, 据此可知此处表示“演得最好”而不是“最差”。故选C。17. C 点拨：此处表达“表演得很好”, 修饰动词performed应用副词well, 故选C。18. D 点拨：上文介绍了电影中的演员Eddie Izzard 和Toby Regbo, 此处应是表达“其他的演员也演得很好”。故选D。19. B 点拨：trouble 麻烦; success 成功; question 问题; problem 难题。根据上文可知, 此处表示“这部电影取得很大的成功”, 故B 项符合句意。20. A 点拨：introduce 介绍; lead 带领; report 报道; record录制。introduce sth. to sb. 是固定短语, 意为“向某人介绍某物”, 本文作者介绍了电影《金银岛》, 故选A。三、【主旨大意】本文是一篇说明文。主要介绍了人工智能技术的应用。其实人工智能并不会像人一样可以进行思考, 但却可以帮助人们去完成一些工作。21. B 点拨：细节理解题。根据文章第一段中的句子“Alex is reading a book about AI, artificial intelligence(人工智能).”可知, artificial intelligence 的缩写形式是AI。22. A 点拨：细节理解题。根据第一段中的句子“He finds the book a little difficult but very interesting.”可知他认为这本书有点难但却很有趣。故选A。23. D 点拨：推理判断题。根据第二段中的句子“So, people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen.”可知, 人工智能并不像人们想象的那样可以和人一样进行思考, 有思维, 故选D。24. A 点拨：句意猜测题。根据第二段中的句子“People will soon find more AI technologies in our lives, such as checking the tickets, the price, people’s faces and fingers.”可知, 人工智能技术未来可以用在检票、计价等方面, 故人类的一些工作可以交给人工智能来完成, 故选A。25. C 点拨：推理判断题。根据第二段中的句子“Actually, AI only uses a lot of information to get the best answer.”可知人工智能仅仅是利用众多信息去得出最佳答案, 故C项表述与短文内容相符, 其余三项表述与短文内容不符, 故选C。
