Google's company, DeepMind, recently said that their research team has created a table tennis robot. This robot can play at the same level as human amateur（业余的）players.
The research team wrote about their work on a website called arXiv. A team member said, “This is the first learning robot. It can learn to play table tennis as well as human amateurs.” The robot has a six-axis（轴）robotic arm that can move back and forth.
In 29 games against human players, the robot won 13 times. The human players were all new to the robot, and their skill levels are different, from beginners to high-level players. The researchers said, “The robot lost all the games against high-level players but won all the games against beginners and 55% of the games against intermediate players.”
To make the robot play at a human level, the team used a layered and modular strategy（分层和模块化的策略）. This means the robot can do basic skills like forehand topspin and backhand blocks. It also has a high-level controller. It acts like a brain. During a game, it can choose the best moves based on the game situation, the robot's abilities and the opponent's（对手）skills.
It's not difficult to see that this robot can play table tennis with amateur players and help them make progress in some way. However, the researchers noted that they still need to improve the robot.
() 28. What can we know from the passage?
A. The robot is called arXiv.
B. The robot has a four-axis robotic arm.
C. The robot can learn like human players.
D. The robot can move up and down.
() 29. What does the underlined word “intermediate” in Paragraph 3 mean?
A. Never played before.
B. Very skilled.
C. Having some experience.
D. Just starting out.
() 30. What can the high-level controller do?
A. Choose the best moves during a game.
B. Change the game situation.
C. Move the robot's arm back and forth.
D. Improve the opponent's skills.
() 31. If the writer continues writing, what will he write?
A. How the robot beats against human players.
B. Why the robot can do basic skills.
C. Where people can buy the robot.
D. How researchers are going to improve the robot.

答案
28.C 29.C 30.A 31.D
解析
【分析】
这是一篇科技类英语阅读理解，共4道题，分别考查细节理解、词义猜测、细节理解和推理判断。解题思路如下：1. 第28题需定位原文各选项对应信息，排除错误选项；2. 第29题结合上下文玩家技能水平分类推断词义；3. 第30题定位原文关于高级控制器的描述找功能；4. 第31题结合最后一段内容推断下文。
【解析】
28题：A选项，原文提到研究团队在arXiv网站发布成果，并非机器人叫arXiv，错误；B选项，机器人是六轴机械臂，不是四轴，错误；C选项，原文明确说明该机器人是首个学习型机器人，能像人类业余选手一样学习打乒乓球，正确；D选项，机械臂是前后移动，不是上下，错误，故选C。
29题：第三段将玩家技能分为beginners（初学者）、intermediate、high-level（高水平），intermediate介于初学者和高水平之间，意为“有一定经验的”，对应选项C；A、D对应beginners，B对应high-level，均错误，故选C。
30题：第四段指出高级控制器像大脑，比赛中可根据情况选择最佳动作，对应选项A；B、C、D均不符合原文描述，故选A。
31题：最后一段提到研究人员仍需改进机器人，下文应围绕如何改进展开，对应选项D；A、B、C与最后一段逻辑不符，故选D。
【答案】
28.C 29.C 30.A 31.D
