They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI(artificial intelligence) can take to its cold, mechanical heart.‎ The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote”. It collects story plots from the Internet and then uses those stories to teach robots how to behave.‎ The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the storekeeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指示), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.‎ Quixote would work best on a robot that has a very limited function. It’s a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.‎ ‎【解题导语】　本文是一篇说明文。童话故事不但可以娱乐孩子们，还能让机器人拥有道德观念，使其更好地为人类服务。‎ ‎1．What function do fairy tales perform in the robots?‎ A．They entertain robots.‎ B．They highlight dangers.‎ C．They make robots more intelligent.‎ D．They enable robots to behave morally.‎ D　解析：细节理解题。根据第一段中的“it has found a way to use the fairy tales as moral ‎ lessons that AI(artificial intelligence) can take to its cold, mechanical heart”可知，童话故事可以作为道德经验让人工智能机器人的行为符合道德规范，故D项正确。‎ ‎2．What is “Quixote” in the text?‎ A．A punishment system.‎ B．A character in literature.‎ C．A big name in technology.‎ D．A kind of software educating robots.‎ D　解析：细节理解题。根据第二段最后两句“This system is called ‘Quixote’.

When students in her class started calling Prisilla a boy, she felt ashamed, often crying and losing focus in school.‎ Her teacher, Shannon Grimm, sympathized with her unhappiness. Grimm and Prisilla’s mom were concerned, but their ideas didn’t work. “We had classroom discussions about how girls ‎ have short hair and boys have long hair, and I showed them photos of movie stars with different looks，” Grimm said, “However, it wasn’t sinking in.”‎ Grimm thought about Prisilla throughout the winter break, and one morning, she had an idea: Cut off her hair—a scary thought for Grimm, who wore her hair long and took pride in it. “I’ve never had short hair, and I stressed about it for two weeks before making a decision，” she said. On Jan. 4, Grimm invited a hairstylist friend to her home. “I told him to keep going, even if I cried，” she said.‎ The class loved their teacher’s new do, especially Prisilla, who excitedly ran off the school bus that afternoon yelling, “Mom, Ms.Grimm cut her hair！” The teacher also bought matching bows for herself and the girl, so they could style their hair together.‎ In February, the teacher recommended Prisilla for the school district’s Student of the Month Award, but during the Monday ceremony, she received a surprise “hero medal” from the girl. “Now we have matching awards，” says Grimm.‎ Prisilla’s mother, Maria, said that Grimm’s thoughtfulness brought her to tears. “I was shocked.

He thought about what to write.‎ He recalled that the competition deadline was merely a week away. But he still had not even started on his piece. He looked at the brochure again. “WRITING COMPETITION！” the title read. His mom had encouraged him to enter the writing competition, and now he was taking it on as his personal task for the holidays.‎ As the boy reflected on his previous writing efforts, he realized how hopeless his task of winning was. Every story he ever wrote was based on other stories. He had little imagination, and unfortunately, imagination was the key to writing.‎ Suddenly, he had a brainwave. This time, he came up with an original and imaginative story.‎ The words shot towards him like a storm of leaves. Words were coming easily, flowing through him, faster than he could type. He typed faster than he ever had before. He continued to type, amazed how easy writing this story was. The boy could not stop writing. He looked at the word count and saw the number “248” staring right back at him. He was not even halfway yet.‎ Then he heard his mother’s call of saying time for bed. He continued writing the piece, ignoring her. He had to make up for the time he had lost in thinking about a topic to write.‎ Finally, he finished. The word count now read “498”．‎ ‎“Perfect，” he thought, “just under the word limit.” He knew this was the story that would win.‎ He went to the website and searched for the competition. He found the page but there was no “Enter” button.‎ Confused, he then reread the page again. It read COMPETITION CLOSED.‎ ‎【解题导语】　本文是一篇记叙文。小男孩坐在电脑前，冥思苦想地进行写作。他参加的是一个网络写作比赛，可是怎么也想不出写作主题。好一会儿后，他茅塞顿开，快速敲击键盘，可是等到他写好文章准备提交时，页面上却显示“COMPETITION CLOSED”。‎ ‎1．What caused the boy to take part in the writing competition?‎ A．A new computer.‎ B．The prize money.‎ C．His own interest.‎ D．His mom’s encouragement.‎ D　解析：细节理解题。根据第二段尾句“His mom had encouraged him to enter the writing competition, and now he was taking it on as his personal task for the holidays.”可知，他的妈妈鼓励他参加写作比赛，现在他把写作作为假期的个人任务；据此可知，他参加写作比赛是他妈妈鼓励的，故D项正确。‎ ‎2．How did the boy finish his earlier writing?‎ A．His mom helped him.‎ B．He copied others’ ideas.‎ C．His friends assisted him.‎ D．He used his imagination.‎ B　解析：细节理解题。根据第三段第二句“Every story he ever wrote was based on other stories.”可知，他之前写的每一个故事都是以其他故事为基础；据此可知，以前写作时，他总是仿照别人的故事写，故B项正确。‎ ‎3．Why did the boy delay his writing?‎ A．Because he was terribly lazy.‎ B．Because he didn’t know what to write.‎ C．Because he wasn’t confident.‎ D．Because he read too many stories.‎ B　解析：细节理解题。根据第一段中的“He thought about what to write.”及第三段的内容“As the boy reflected on his previous writing efforts, he realized how hopeless his task of winning was...He had little imagination, and unfortunately, imagination was the key to writing.”及倒数第五段尾句“He had to...write.”可知，想象力是写作的关键，而他又缺乏想象力；另外，由于他不知道写什么，所以他延误了写作时间，故B项正确。‎ ‎4．Which might be the maximum word limit for each entry?‎ A．100.

They also help each other out whenever there’s trouble.‎ Personality, just as among people, varies among trees. Some are anxious, some bold. On the author’s land，there are three oak trees growing close together. One of the oak trees always starts to shed its leaves two weeks earlier than the others. Since they all experience the same temperature，the same soil and the same length of day, such variables can’t be the explanation. So what’s happening？Well，this tree is simply more careful than the others. Whoever holds on to their leaves longer can do more photosynthesis(光合作用) and store more nutrients. However, the longer a tree keeps its leaves, the higher the risk of injury.‎ Not only do trees make their own decisions, they also learn from their mistakes. A tree, for example, keeping its leaves too long during one year will never make this mistake again. This leads to several other conclusions: trees must notice the temperature and the length of the day and be able to save their experiences somewhere. Obviously, trees don’t have brains, but it is thought that in the sensitive tips of their roots they keep track of information and experiences.‎ But trees aren’t only clever when it comes to caring for themselves. They also support each other whenever there’s trouble by giving warnings and even taking care of sick and weak conspecifics with nutrients. For example, one time the author found a very old tree stump. Its insides had rotted a long time ago to topsoil. But the wood on the outside of the stump was still living. How was this possible？Well, the stump was nourished by its neighbors with nutrients from the root system, and had been for at least 400 years!‎ Why do trees do__such__a__thing？It’s simple: it’s better together. Trees need the forest; it protects them from storms, provides the right microclimate and warns them of attacks.‎ ‎【解题导语】　本文是一篇说明文，主要介绍了树的智慧：每棵树都有它不同的个性，遇到困难时它们也会互相帮助。研究发现，树不但能自己做决定，还能从自己的错误中吸取教训。‎ ‎5．Why does the author mention the three oak trees?‎ A．To illustrate trees can learn from experiences.‎ B．To show trees can make independent decisions.‎ C．To explain trees are quite supportive to each other.‎ D．To prove trees have the same personalities as humans.‎ B　解析：推理判断题。根据第二段第四句“One of the oak trees always starts to shed its leaves two weeks earlier than the others.”可知，三棵橡树中，有一棵总比其他两棵先落叶；结合第三段第一句“Not only do trees make their own decisions, they also learn from their mistakes.”可知，树木能自己做决定。据此可推知，作者提及三棵橡树旨在说明树木可以自己做决定，故B项正确。‎ ‎6．According to the text, which of the following best describes general features of trees?‎ A．Anxious and bold.‎ B．Smart and adventurous.‎ C．Helpful and wellbehaved.‎ D．Adaptable and supportive.‎ D　解析：推理判断题。根据第三段第一句“Not only do trees make their own decisions, they also learn from their mistakes.”，并结合第三段内容可知，树木不仅能自己做决定，还能从自己的错误中吸取教训。据此可推知，树木适应能力强。根据第四段第一、二句“But trees aren’t only clever when it comes to caring for themselves. They also support each other whenever there’s trouble by giving warnings and even taking care of sick and weak conspecifics with nutrients.”可知，树木不仅善于照顾自己，当遇到困难时，它们会发出警告，相互支持，甚至照顾生病、虚弱的同类；据此可推知，树木之间互帮互助，故D项正确。‎ ‎7．What does the underlined phrase “do such a thing” mean?‎ A．Give warnings. B．Offer assistance.‎ C．Depend on others. D．Provide nutrients.‎ B　解析：词义猜测题。根据第四段尾句“Well，the stump was nourished by its neighbors with nutrients from the root system, and had been for at least 400 years！”可知，树桩是由它的邻居从根处给予营养来滋养的；结合第五段第一句“Why do trees do__such__a__thing？”和其后的内容可知，该处表示“为什么树木要互相帮助？”，故画线短语是指提供帮助，故B项正确。‎ ‎8．Where does this text most probably come from?‎ A．A public lecture. B．A science book.‎ C．An experiment report. D．A travel journal.‎ B　解析：文章出处题。通读全文可知，本文是一篇说明文，主要介绍了树的智慧：每棵树都有它不同的个性，遇到困难时它们也会互相帮助。研究发现，树不但能自己做决定，还能从自己的错误中吸取教训。据此可推知，本文最可能选自科学书籍，故B项正确。‎ 七选五 ‎(2020·大连高三双基测试)Have you ever had times questioning yourself and feeling discouraged?
