This robot can play at the same level as human amateur (业余) players. ②The research team wrote about their work on a website called arXiv. A team member said, “This is the first learning robot that can play ping-pong as well as human amateurs.” The robot has a six-axis robotic arm that can move back and forth and side to side on a rail at the bottom. ③In 29 games against human players, the robot won 13 times, which is a win rate of 45%. The human players were all new to the robot, and their skill levels ranged from beginners to advanced 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.” ④To 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 that 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 skills. After the game, the robot can analyze (分析) the data and improve its skills. ⑤The researchers noted that the robot still has some weaknesses. For example, it is not very good at backhand shots and has trouble with fast, high, low, or strongly spinning balls. They plan to improve the robot by making better control algorithms (算法) and better hardware. 16．Which of the following is right according to 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 on a rail at the bottom. 17．What does the underlined word “intermediate” mean in Para. 3? A．Never played before B．Very skilled. C．Have some experience D．Just starting out 18．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 robot’s hardware. 19．What is the structure of the passage? A． B． C． D． 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$ Unit 3 Robots 第3课时 Grammar 分层练习 1．The new robot made a great (different) to our everyday life. 【答案】difference 【详解】句意：新机器人对我们的日常生活产生了很大的影响。make a great difference是固定词组，意为“产生巨大的影响”。故填difference。 2．My washing machine doesn’t work, so I will have it (repair). 【答案】repaired 【详解】句意：我的洗衣机坏了，所以我要把它修理一下。repair“修理”，动词。have sth. done“使某物被做”，过去分词作补足语。故填repaired。 3．I don’t know how (make) the little boy laugh. 【答案】to make 【详解】句意：我不知道怎样逗这个小男孩笑。此处是结构“疑问词+动词不定式”作宾语。故填to make。 4．My robots are smart enough (help) me with my homework. 【答案】to help 【详解】句意：我的机器人足够聪明，可以帮我做作业。此处是结构adj. enough to do sth.“足够……做某事”。故填to help。 5．The little boy is so worried in the exam because he doesn’t know when (hand) in the paper. 【答案】to hand 【详解】句意：这个小男孩在考试中非常担心，因为他不知道什么时候交卷子。“特殊疑问词+to do”是宾语从句的简化，hand in意为“上交”。故填to hand。 二、完成句子 6．I really don’t know which apple I should take.（改为简单句） I really don’t know which apple . 【答案】 to take 【详解】句意：我真不知道该拿哪个苹果。分析原句可知，原句包含宾语从句，且从句的主语和主句的主语一致，在这种情况下，此从句可转化成“疑问词+动词不定式”结构。故填to；take。 7．The young man is very strong and he can carry the big box.（改为简单句） The young man is to carry the big box. 【答案】 strong enough 【详解】句意：这个年轻人很强壮，他能搬动这个大箱子。改为简单句可表示“足够强壮，能够搬动这个大箱子”，用... enough to do sth.表示“足够……可以做某事”，is后接形容词strong作表语，enough置于形容词之后。故填strong；enough。 8．Nick was so tired that he couldn’t walk any further.（改为简单句） Nick was any further. 【答案】 too tired to walk 【详解】句意：尼克非常累以至于他不能走得更远了。too…to…“太……而不能……”可以作为so…that…“非常……以至于……”句型的同义转换， 详细结构为too + adj. + to do sth.，此 处形容词adj.为tired, to后动词用原形，即walk，故填too；tired；to；walk。 9．Now I will show you how you can operate this machine. (改为同义句) Now I will show you operate this machine. 【答案】 how to 【详解】句意：现在，我将向你展示如何操作这台机器。对比题中两句话可知，原句应转换的部分是“how you can”，在句中做show的宾语，与后面的部分构成宾语从句。且在有宾语从句的句子中，当主句的谓语动词是ask、tell、show、teach等，且宾语从句的主语和主句的间接宾语一致时，宾语从句可以简化为“特殊疑问词+不定式”结构，即how to do sth，故填how；to。 10．I can’t decide where I will go with him. (改为同义句) I can’t decide where with him. 【答案】 to go 【详解】句意：我不能决定和他去哪里。此处可以把where引导的宾语从句简化为“特殊疑问词+to do不定式”的结构，故填where；to go。 三、单项选择 11．Don’t look! You should keep your eyes ________. A．close B．closing C．closed D．closes 【答案】C 【详解】句意：不要看！你应该闭上眼睛。 考查固定搭配。close关闭，动词原形；closing关闭，动名词形式；closed关着的，形容词；closes关闭，动词第三人称单数。keep sth adj“保持某物是……的状态”，此处用形容词closed。故选C。 12．When I passed the classroom, I saw a girl ________ in it. A．draw B．losing C．drew D．drawing 【答案】D 【详解】句意：当我经过教室时，我看见一个女孩在里面画画。 考查现在分词作补足语。draw画画（动词原形）；losing丢失（现在分词）；drew画画（过去式）；drawing画画（现在分词）。根据“When I passed the classroom, I saw a girl…”可知，与之同时发生的动作see是一般过去时，并且“see看见”的内容是正在进行的动作。表达“看见某人正在做某事”用see sb. doing sth.，doing sth.作宾语补足语。选项D“画画”符合语境。故选D。 13．More and more couples prefer ________ a second baby ________ their first child can feel less lonely. A．have; in order to B．to have; in order to C．have; so that D．to have; so that 【答案】D 【详解】句意：越来越多的夫妇想要第二个孩子，这样他们的第一个孩子就不会那么孤独。 考查非谓语动词以及连词辨析。in order to为了，后应接动词原形；so that“以便，为了”，后跟目的状语从句。根据“prefer”可知 ，prefer to do“更喜欢做某事”，因此此处应用不定式作宾语；根据“their first child can feel less lonely”可知，空后为从句，因此应用so that。故选D。 14．My brother is only five years old. He is ________ young ________ answer such a difficult question. A．so; that B．too; to C．to; too D．such; that 【答案】B 【详解】句意：我弟弟只有五岁。他太小了，无法回答这样的一个难题。 考查动词不定式作结果状语。so…that如此……以至于……；too…to太……以至于不能做……；to…too去……太……；such…that如此……以至于……。根据“My brother is only five years old.”可知，他年纪小，因此不能回答难题，young为形容词，因此应用too+adj./adv.+to do sth表示“太……以至于不能做……”。故选B。 15．—This math exercise is ________ difficult ________ I can’t work it out. —Come on! Use your head and you will find a way. A．too; to B．such; that C．so; that D．so; which 【答案】C 【详解】句意：——这道数学题如此难以至于我计算不出来。——加油！动动脑，你会找到一种方法来解题的。 考查结果状语从句。too…to太……而不能……；such/so…that…如此……以至于。根据“This math exercise is…difficult … I can’t work it out”可知，数学练习题太难了以至于解不出来，修饰形容词difficult，用so…that引导的结果状语从句，故选C。 四、阅读理解 ①Google’s company, DeepMind, recently announced that their research team has created a ping-pong robot.
