A team from OpenAI, an artificial intelligence lab in San Francisco co-founded by Elon Musk, has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek. The bots also learned how to use basic tools and that disobeying the laws of physics can help to win. In April, 2019, a team of bots known as the OpenAI Five beat the human world champions at the team-based video game Dota 2. The hide-and-seek bots use similar principles to learn but the simpler game allows for more inventive play.Bowen Baker at OpenAI and his colleagues wanted to see if the team-based dynamics of the OpenAI Five could be used to create skills that could one day be useful to humans. The researchers set their bots loose in a simulated(模擬的) environment filled with fixed walls and movable boxes and left them to play team games of hide-and-seek millions of times. The bots each had their own view of the world and couldn’t communicate with each other directly. At first, the hiders simply ran away. However, they soon worked out that they could find objects in the environment to hide themselves from view. For example, they learned that boxes could be used to block doorways and build simple hiding places. The seekers learned that they could move a ramp(斜坡) around and use it to climb over walls. The bots then discovered that being a team player was the quickest way to win.The hiders also learned to sabotage the other team, such as hiding the ramp before hiding themselves so that the other team can’t make use of the ramp. “Once one team learns a new strategy, it creates this pressure for the other team to adapt,” says Baker.Such tricks show that AIs are able to find solutions that humans miss, says Baker. “Maybe they’ll even be able to solve problems that humans don’t yet know how to.” However, there’s still a long way to go from online hide-and-seek to real problem-solving.1.

Which of the following can replace the underlined word “sabotage” in Paragraph 4?A. Help. B. Prevent. C. Take charge of. D. Keep up with.4. What may the author tell in the following paragraph?A. Advantages of AI bots over humans. B. Lessons from online hide-and-seek.C. Possibilities of AI in real problem-solving. D.

Such improvements are sure to be popular with 5G users worldwide. While it is said to start only in some few areas of the United States this year, much of the rest of the world is not expected to receive this service until 2023. One project in Britain, though, is already testing the superfast technology, but not on humans. Instead, the experimental subjects(實驗對象) are unlike the group of Internet users—cows. The system connects the animals to 5G in an effort to automate(使自動化) the milking process. The project was developed by American technology company Cisco Systems. Testing areas were set up on farms in three rural areas of England. The cows are equipped with 5G-connected devices(設備) that are linked to a robotic milking system. The system uses sensors(傳感器) and machine learning to fully automate the process. System designers say technology takes over after a cow is ready to be milked and walks towards an automatic gate. The device is designed to recognise each cow. It then positions devices to the right body position for milking. During the process, machines offer food for the cow as a reward. One of the test areas is in the town of Shepton Mallet in southwest England. There, about 50 of the farm’s 180 cows are fitted with 5G smart collars(智能項圈) in ear sensors. Project officials say the devices do not harm the cows and the sensors help farmers immediately find any problems or health concerns. Duncan Forbes, the project leader, tells Reuters that so far, he thinks the project shows the farm’s 180 cow operations can be greatly improved with 5G technology. Forbes adds that the experiment provides strong evidence that 5G technology can be widely used in the future “not just on farms, but in rural communities right across the country.”5. What do we know about 5G technology from the first two paragraphs?A. It has changed our lives. B. It has more users than 4G. C. It has not been widely used. D. It is used on cows in the USA. 6. What is Paragraph 4 mainly about?A. The introduction of 5G devices. B. The milking process with 5G technology. C. The purpose of system designers. D. The way machines provide cows with food. 7. Why are some cows fitted with ear sensors?A. To recognise every cow. B. To judge the position of the cow. C. To reduce the harm from devices. D. To find health problems in cows. 8. What is Forbes’ attitude to the future of 5G technology?A. Doubtful. B. Hopeful. C. Disapproving. D. Uncaring.

A【語篇解讀】本文是一篇說明文。文章主要介紹了一種新型的人工智能機器人及這種機器人的特點。C　細節(jié)理解題。根據(jù)第一段第二句中的A team from OpenAI, an artificial intelligence lab in San Francisco可知，OpenAI是舊金山的一個人工智能實驗室，由此可知，OpenAI是一個科學實驗室。A　推理判斷題。根據(jù)第一段第二句“A team from OpenAI… has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek.”可知，人工智能機器人通過玩捉迷藏來學會合作，它們發(fā)現(xiàn)團隊合作是最快的獲勝方式，由此可知，這些機器人學會了團隊合作，為了勝利而共同努力。B　詞義猜測題。根據(jù)畫線單詞句中such as hiding the ramp before hiding themselves so that the other team can’t make use of the ramp可知，隱藏者在隱藏自己之前先隱藏斜坡，這樣另一個團隊就無法利用斜坡。由此可知，隱藏者學會了如何阻礙另一個團隊，故選B項。D　推理判斷題。根據(jù)最后一段最后一句“However, there’s still a long way to go from online hide-and-seek to real problem-solving.”可知，人工智能技術要想真正的解決問題還有很長的路要走，由此可知，作者在下一段可能會介紹此類人工智能技術應用到現(xiàn)實生活中會遇到什么困難，有哪些局限性，故選D項。B【語篇解讀】本文是一篇說明文。文章主要介紹了奶牛成為英國首批5G用戶，連接到5G的奶?？梢钥刂谱约簲D奶。C　推理判斷題。根據(jù)文章前兩段，特別是第一段最后一句“While it is said to start...this service until 2023.”可以推斷，5G技術還沒有被廣泛使用。B　主旨大意題。根據(jù)文章第四段內(nèi)容可知，本段主要介紹采用5G技術的擠奶過程。D　細節(jié)理解題。根據(jù)文章第五段第三句“Project officials say the devices...or health concerns.”可知，這種耳部傳感器可以幫助農(nóng)民發(fā)現(xiàn)奶牛的健康問題。B　推理判斷題。根據(jù)文章最后一段內(nèi)容可推斷，Forbes對5G技術的應用前景充滿了希望。
