（2020·广东·深圳实验学校高中部高一期末） While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world’s first kids to be “taught” by a digital teacher, Will. Will is just an avatar(用户头像)that appears on the students desktop, tablet, or smartphone screen, not a human-like robot walking around the classroom.
Auckland energy company Vector and AI company Soul Machines worked together to develop Will, which has been modeled after the human brain and nervous system, allowing it to perform human-like behavior. The digital teacher is currently assigned to teach Vector’s “Be sustainable with energy,” a free program for Auckland elementary schools.
Just like the humans it replaced, Will is able to instantly react to the students’ responses to the topic. Thanks to a webcam(网络摄像头)and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues(非口头提示). For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps capture the students’ attention, but also allows the program’s developers to monitor their participation, and make changes if needed.
Vector’s Chief Digital Officer, Nikhil Ravishankar says, “What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention.”
Will, in place since August 2018, has been a great success so far. However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon. For. one, the avatar’s knowledge base is severely restricted. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a “personal tutor”, providing kids with one-on-one help on specific subjects or even topics.
31．What is Willable to do in class?
A．Think like humans. B．Satisfy all kids’ needs.
C．Interact with the students. D．Monitor students’ participation.
32．What's Nikhil Ravishankar’s attitude towards Will?
A．Positive. B．Negative. C．Doubtful. D．Unconcerned.
33．What is mainly discussed about Will in the last paragraph?
A．Its popularity. B．Its limitations. C．Its applications. D．Its convenience.

（2021·浙江·高一阶段练习）Though the Tokyo Olympic Games drew to a close on Aug 8, the public is still watching the athletes. Their outfits and the cutting-edge technologies that helped them in the competition have aroused people's interest.
Su Bingtian, the first Chinese sprinter (短跑运动员) to reach an Olympic 100m final, has owed his breakthrough to scientific training, "It takes Su 47 steps to run 100 meters. Each step counts." Liang Dong, a member of Su's training team, told Shenzhen Evening news. "Randy Huntington. Su's American coach and a biomechanics (生物力学) expert in track and field, has collected a lot of data on outstanding sprinters and built a database. He put in all of Su's data and got a nearly perfect model. When Su is training, the team uses high-speed cameras to record his training and compares it with the model to find out his weaknesses."
The technologies have also brought a new boost to table tennis. On July 27, the semifinal match between China's Sun Yingsha and Japan's Mima Ito was in full swing at the Tokyo Metropolitan Gymnasium. You wouldn't have guessed that besides players, judges and audiences, a powerful Al platform was monitoring the match.
Every movement of Mima Ito was recorded by this Al cloud platform. At an average speed of 100 Mbps, the data was sent to the technical team of the Zhejiang University Table Tennis Intelligent Big Data Analysis Platform, 2,442 kilometers away from the Tokyo Metropolitan Gymnasium, according to The Paper.
The platform has stored the data of more than 8,000 matches so far. The research team has been working on match simulation (模拟) since 2018. "Using big data and Al, we can precisely simulate and predict how the winning rate will change when players change certain strategies," Professor Wu Yingcai, the main developer of the platform, told CCTV-2.
The Tokyo Olympic Games have seen not only scientific support in training, but many technologies in athletes' devices. For example, the Kenya women's volleyball team's GPS devices fed data on each player's blood pressure, heart rate and so on to coaches, who used the information to prevent injury and personalize training plans for each athlete. South China Morning Post reported.
34．The underlined word "cutting-edge" in paragraph 1 probably means "_________”.
A．special B．advanced
C．handmade D．unique
35．What's the advantage of match simulation according to Wu?
A．It helps judges provide objective comments.
B．Players can know their own weaknesses.
C．It helps players improve their winning rate.
D．Players can study other players' strategies.
36．The GPS devices can help coaches__________.
A．fully understand players' fitness level
B．make better decisions for future training.
C．give proper treatment for sports injuries
D．track players' movement during the game
37．What does the article mainly talk about?
A．The ways athletes prepared for the Tokyo Olympics.
B．The advantages of using Al at the Tokyo Olympics
C．The highlights of the Tokyo Olympics
D．Technologies that helped athletes at the Tokyo Olympics.

（2021·安徽·高一阶段练习） Look at the keyboard of any standard typewriter or computer. “Q,”“W,”“E,”“R,”“T” and “Y” are the first six letters. Who decided on this arrangement of the letters? And why?
People tried for centuries to invent the typewriter. In 1714 in England, Henry Mill applied for a patent (专利) for a machine called An Artificial Machine or Method for the Impressing or Transcribing of Letters Singly or Progressively One After Another. That machine probably didn’t sell because no one could remember its name.
The first practical typewriter was patented in the United States in 1868 by Christopher Latham Sholes. His machine was known as the typewriter. It had a keyboard on which the letters were arranged in alphabetical order (按字母顺序).
But on the first model, his “ABC” key arrangement caused the keys to jam (拥堵) when the typist worked quickly. To solve the problem, he just kept the typist from typing too fast. Sholes asked his brother-in-law to rearrange the keyboard so that the letters used often were not so close together and the type bars (打字杆) would come from opposite directions. Thus they would not hit together and jam the machine. The new arrangement was QWERTY arrangement that typists use today. Of course, Sholes claimed that the new arrangement was scientific and would add speed and efficiency. But the only efficiency it added was to slow the typist down, since almost any word in the English language required the typist’s fingers to cover more distance on the keyboard.
The advantage of the typewriter outweighed (超过) the disadvantages of the typewriter keyboard, however. Typists memorized the crazy letter arrangement, and the typewriter became a huge success. By the time typists had memorized the new arrangement of letters and built up their speed, typewriter technology had improved, and the keys didn’t stick as badly as they had at first.
38．Who was the inventor of the first practical typewriter?
A．Henry Mill. B．Sholes’ brother-in-law.
C．Christopher Latham Sholes. D．Henry Milts brother-in-law.
39．Why could the machine invented by Henry Hill not be sold?
A．The keyboard had great disadvantages.
B．Perhaps the name of the machine was too long.
C．It was difficult for people to use it.
D．It hadn’t been patented by its inventor.
40．Why did Sholes decide on the QWERTY arrangement of the keyboard?
A．To solve the problem of the keys jamming.
B．To compete with the “ABC” key arrangement.
C．To arrange the letters in alphabetical order.
D．To cause the keys to jam when the typist worked quickly.
41．What can be inferred from the QWERTY arrangement of the keyboard?
A．It was easy for typists to memorize.
B．It could make the type bars move faster.
C．It kept the typist from typing too fast.
D．It could let the typist cover less distance on the keyboard.

（2021·广东东莞·高一阶段练习）Facebook has developed a kind of AI (人工智能) translating between any pair of 100 languages without depending on first translating to English.
Facebook’s system was trained on a data set of 7.5 billion sentence pairs collected from the web across 100 languages, though not all the languages had an equal number of sentence pairs. “What I was really interested in was cutting out English as a middle man. Globally there are plenty of countries where they speak two languages that aren’t English,” says Angela Fan of Facebook AI, who led the work.
For some language pairs, the new system shows prominent improvements in translation quality. For example, translating from Spanish to Portuguese is extremely strong because Spanish is the second-most spoken first language worldwide, meaning the researchers can get a lot of data. Translation between English and Belarusian (白俄罗斯语) also is improved because the AI can translate Russian into English, which shares similarities with Belarusian.
While the system isn’t in use on the social network site, Facebook plans to put it to work soon to manage the 20 billion translations made every day when people click “Translate” on posts (帖子) written in more than 160 languages. “Future work will be done on other languages,” says Fan, “especially for languages where we don’t have a lot of data, like South-East Asian and African languages.”
The work “breaks away from the English-centric models and tries to build more different models,” says Shelia Castilho of the ADAPT Centre at Dublin City University, Ireland. “That’s pretty new and different. But it’s hard to know if the AI does a right translation work,” says Castilho. “The users may not know the other language, so they cannot judge the correctness of the translation.”
42．What’s Angela Fan’s purpose of doing the research?
A．To collect data of all kinds of people.
B．To make learning different languages easier.
C．To achieve her dream of becoming a translator.
D．To avoid using English as a middle man in translation.
43．Why is it easy to translate from Spanish to Portuguese by AI?
A．There is much data on Spanish.
B．Portuguese is similar to Spanish.
C．Researchers have a good knowledge of the two languages.
D．Spanish is spoken by the largest number of people.
44．What is Castilho worried about?
A．The safety of AI translation. B．The correctness of AI translation.
C．The way of using Facebook. D．The number of posts on the website.
45．What is the best title for the text?
A．Facebook AI Can Talk with the Users
B．Facebook Wants to Buy a New System
C．Facebook AI Can Translate Any Pair of 100 Languages
D．Facebook Has Lost Many Users

（2021·辽宁·高一阶段练习）Electronic media such as email, instant messaging, video games, and television, has influenced almost every aspect of our daily lives. 46． While some media exposure can be useful and informative (增进知识的), too much screen time takes away from other activities.
Screen time becomes a particularly important issue when discussing children’s use of media. Experts now recommend children’s screen time should be limited to no more than 2 hours per day, including television and non—school related computer usage. 47．
Unfortunately, it appears that this recommendation is not followed in most families. One recent study found that children between the ages of 8 and 18 spend nearly 45 hours per week watching television, playing video games, and surfing the Internet. 48． Besides, much of the electronic media that makes up children’s screen time is filled with inappropriate (不合适的) contents.
49． First, never allow televisions and computers in your child’s bedroom. Avoid using television, video games, and computer time as a reward for good behavior. Provide plenty of other recreational activities for your child to enjoy and set a good example for your child with regard to your own media usage.
It’s important to serve as a model of healthy electronics use for your children. 50． Keeping the TV on for background noise all the time and scrolling (滚屏) through your phone any time will teach your child bad habits.
A．Most children know more about electronics than adults do.
B．Kids easily grow dependent on technology for entertainment.
C．Parents should think of ways to manage their children’s screen time.
D．This is more time than they spend doing homework, or reading for pleasure.
E.However, the effect of being all the time in front of a screen is not entirely positive.
F.So before you watch your favorite TV series, remember to set a good example.
G.Children under the age of 2 are generally encouraged to have no screen time at all.
