（2021·浙江·杭州市余杭区杭州二中树兰高级中学高一开学考试）3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and model cars. People and businesses are able to create the things they need very quickly and easily using 3D printers.
But can you imagine printing food? Some scientists are trying to create a new dining experience by doing this. They hope that having a 3D printer in the kitchen will become as common as the microwave or the fridge. Scientists say that they are easy to use: you simply have to choose what you want to eat and put the uncooked food ‘inks’ into the printer. You can also change the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and healthy meals.
Using 3D printers to create your meals would also be saving the environment. There would be less need for traditional growing and transporting as food production would be much simpler. Printing food could also help people who are experiencing the swallowing disorder. They could make the printer to print softer foods so that they would not have trouble swallowing them.
However, some people think that a future of 3D­-printed food would cause many problems. It could take away many jobs, including those for growing and transporting food. Likewise, traditional cafés and restaurants might lose business. Also, people are worrying about whether the printed food is nutritious: Is it really possible to get the nutrients we need from food­based inks? What’s more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

（2021·四川·威远中学校高一阶段练习） Surfing the Internet for fun will make you a better employee, according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive (有效率的) than those who do not. Study author Brent Coker said “Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,” Coker said on the university’s website.” Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day’s work, and as a result, increase productivity (生产效率),” he said.
According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.” Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online,” said Coker. “That’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.
8．What does the University of Melbourne study mainly show?
A．People who surf the Internet are good employees.
B．Not everyone surfs the Internet for fun during office hours.
C．Surfing the Internet for fun during office hours increases productivity.
D．The Internet is becoming more and more important in people’s life.
9．According to paragraph 3, Brent Coker would most probably agree that ________.
A．the longer a person’s mind rests the better attention he will have.
B．surfing the Internet is the best way to increase productivity.
C．workers should have a long break during office hours
D．workers should let their minds rest now and then.
10．The underlined word “block” in paragraph 4 means “________”.
A．prevent B．cycle C．burst (爆裂) D．breathe
11．What can we infer from the last paragraph？
A．People should spend as little time as possible surfing the Internet.
B．Those who never surf the Internet have the lowest productivity.
C．Most people don’t surf the internet in moderation during office hours.
D．Spending too much time surfing the Internet reduces productivity.

（2021·江苏如皋·高一期中）A team of researchers has created a website—emojify.info, where the public can try outemotion recognition systems through their computer cameras. Researchers hope it can make the public know about the technology and promote discussions about its use.
“It is a form of facial recognition, but it goes further because rather than just identifying people, it claims to read our emotions and our inner feelings from our faces,” said Dr Alexa Hagerty, project lead and researcher at the University of Cambridge Leverhulme Centre for the Future of Intelligence and the Centre for the Study of Existential Risk.
Hagerty said many people were not aware of how common emotion recognition systems were, noting they were used in situations ranging from job hiring, to airport security and even to education to see if students are doing their homework. Such technology, she said, was in use all over the world, from Europe to the US and China.
However, Hagerty emphasized that emotion recognition technology might have some potential benefits, but these must be weighed against concerns around accuracy, human rights, as well as whether the technology was even the right tool for a particular job.
In one game, users are invited to pull a series of faces to fake emotions and see if the system is fooled. “It is said that the technology is reading emotions,” said Hagerty. But, she added, actually, the system was reading facial expressions and then combining them with the assumption that those movements are linked to emotions, for example, a smile means someone is happy. However, human experience showed it was possible to fake a smile. “That is what that game was: to show you didn't change your inner state of feeling rapidly six times, you just changed the way you looked on your face,” Hagerty said.
Some emotion recognition researchers say they are aware of such limitations. Vidushi Marda, senior programme officer at the human rights organization Article 19 said it was important to stop the growing market for emotion recognition systems. She said, by reading and classifying human beings into categories that touch upon the most personal aspects of humans, emotion recognition technology doesn't also agree with human rights, according to the organization's website.
“The important learning from the development and use of facial recognition systems across the world has been to question the validity and the necessity for technologies early and often, and projects that focus on the limitations and dangers of emotion recognition are an important step in that direction,” she said.
12．Why did researchers create emojify.info?
A．To improve emotion recognition technology.
B．To bring emotion recognition into public daily life.
C．To draw public attention to emotion recognition technology.
D．To call for more researchers to study emotion recognition technology.
13．What does the third paragraph mainly focus on?
A．The potentials of emotion recognition technology.
B．The wide use of emotion recognition technology.
C．The advantages of emotion recognition technology.
D．The rapid development of emotion recognition technology.
14．What can we learn about the website of emojify.info?
A．It will often fool the users.
B．It can accurately read users' emotions.
C．It recognizes expressions rather than emotions.
D．It sounds an alarm when people fake a smile.
15．What does Vidushi Marda think of emotion recognition systems?
A．A losing battle B．A quick-fix method
C．A high point D．A well-meant proposal

47．（2021·安徽·宿州高一期末）阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。续写的词数应为150词左右。
I fetched my mail as usual. Suddenly a colorful flyer (小传单) jumped into my sight. In the middle was a drawing of an old-fashioned phone, like the one my great-aunt Sara owned 40 years ago and at the bottom was a phone number. Running over it, I couldn’t help laughing.
“Is that mail funny?” my ten-year-old daughter, Jenny, asked.
“Not really,” I admitted. “It’s about the wake-up service. Outdated already.”
“What’s that?” she frowned (皱眉). I explained how, before smart phones, people sometimes paid someone to wake them with a call.
“Who sent this flyer?” she pressed.
I shook my head. “Probably someone older and he could need some money,” I said.
Her eyes lit up. “Can we order a wake-up service?” she asked.
“No kidding. With smart phones at hand, who will need it? And it’s not cheap at all. $2.5 per day.” I picked up the flyer and headed for the recycling bin.
“Wait!” she shouted.
“I feel sorry for the wake-up man, if he needs some money,” she said in tears. “Can’t we order one?”
I looked at the flyer with its drawing of an old-fashioned phone. I remembered, again, my great-aunt Sara and her old phone. As a kid, I used to visit her on Labor Day when Jerry Lewis would host his charity(慈善) event for the disabled kids. Aunt Sara would grasp my hand tightly and then reach for the telephone, dialing the number on the screen. Holding the receiver between us, we’d announce to the operator, “We’d like to help those kids.”
But now here was my own child, showing the same heart I had once been encouraged to have, and how could I ignore (不理睬) her? I googled the flyer’s telephone number. The number belonged to a man called Raymond.
Paragraph 1:
Jenny dialed the number.

【分析】
本文是一篇说明文。文章介绍了电脑的演变过程，从简单的计算到联网，在很多领域起着越来越重要的作用。
36．考查非谓语动词。修饰名词machine用非谓语动词，此处用动名词形式表示被修饰语的用途，故填calculating。
37．考查动词。could后接动词原形，故填 simplify。
38．考查固定句型。句意：我发展很慢，花了近两百年的时间，我才被查尔斯·巴贝奇（CharlesBabbage）建造成一台分析机器。It takes+段时间+before+其它成分是固定句型，表示“花费了多长时间以后才……”，it做主语，置句首单词首字母大写，故填It。
39．考查定语从句引导词。这里是一个限定性定语从句，先行词是an operator，且从句缺少主语，因此要用who或者that来引导，故填who/that。
40．考查副词。此处用副词修饰动词could think，故填logically。
41．考查动词时态。根据时间状语In 1936可知，描述过去发生的事情，应使用一般过去时，故填wrote。

43．考查介词。From then on“从那时起”是固定短语，故填on。
44．考查形容词比较级。根据下文“First as a PC ,and then as a laptop.（先是台式电脑，然后是笔记本电脑）”可知，随着时间的推移，我被制作的更小。small作宾语补足语用形容词比较级。故填smaller。
45．考查动词时态及语态。根据时间状语since the 1970s可知，表示过去发生，一直持续到现在的动作用现在完成时，且主语I与use是被动关系，故填has been used。
46．With the development of science and technology, the Internet has changed our way of life, making our life more convenient. However, communication on the Internet has brought new challenges for parents. As parents, you should play an important role in helping children have safe and positive experiences on the Internet. Here are some tips.
To begin with, talk with your child about staying safe online and the importance of good behavior online. What’s more, the best safety tip is to never share personal information until you’re quite sure that it’s safe to do so. Last but not least, teach your child to report or talk to you if they feel uncomfortable or threatened online.
I hope my suggestions will be of great use to you.

47．One possible version:
Paragraph 1:
Jenny dialed the number. To her surprise, the voice was quite young, soft and friendly. “Can I order the wake-up service?”Jenny asked. “Sure. At your service all the time,” Raymond replied. “How about 6 o’clock tomorrow?” “No problem. I will call you every five minutes until you get up.” Suddenly a strong sense of warmth and joy filled her heart like the sunshine.
Paragraph 2:
“Ring, ring, ring” went the phone at 6 o’clock sharp. In no time Jenny jumped to her feet and picked up the phone. “Good morning,” came the same voice. “Morning,” Jenny was too excited to continue the conversation. “Uh, huh...” she rubbed her eyes and asked, “How should I pay you?” “Apple Pay.” “What?!” Jenny screamed. As if having read her mind, Raymond said calmly, “Technology cannot really replace humans and humans cannot live without technology either. By the way, $2 out of $2.5 will be given away to a charity for kids. Thank you for your kindness! Have a good day!”
【分析】
本文以“叫醒服务”为线索展开。讲述作者收到一张传单，内容是“叫醒服务”，一开始作者觉得很好笑，因为在智能手机的时代，应该不会有人再需要电话叫醒服务了，并且还觉得价格有点贵，而作者的女儿却对这个事情感兴趣，加之作者对儿时和萨拉姑姑拨打电话为儿童慈善活动筹款的记忆，于是决定预定这项服务帮助做这份工作的人。
【详解】
1.段落续写：
①由第一段首句内容“Jenny拨打了这个号码”可知第一段描写接通电话后的情景，包括对方的声音以及约定叫醒时间。
②由第二段首句内容“铃铃铃，电话铃在6点钟整响起。”可知第二段应该描写叫醒服务中发生的事情，包括支付方式以及对服务表示感谢。
2.续写线索：决定预定叫醒服务——约定叫醒时间——收到醒服务——支付并感谢。
3.词汇激活
行为类
①打电话：dial/call/make a phone call/pick up the phone
②起床：get up/ to wake up/get out of bed
③问答：ask/reply/answer/ continue the conversation
情绪类
①态度：soft/friendly/calmly/answer with patiently and politely
②感受：sense of warmth and joy/feel warm and happy/ excited
