“There are more people actively learning a language through DuoLingo than in the entire US public school system.” says Luis von Ahn, founder of the free language learning app. Since its launch (投放市场) in 2012, more than 30 million people have downloaded (下载) the app, which gamified education and attracted many language learners.
The growth of technology for educational use has changed the way in which people learn and receive education. This is particularly true for languages, an area in which the explosion of mobile apps and interactive software has provided choices to a range of people who were previously unable to receive foreign language education.
Von Ahn says that when he founded DuoLingo he decided to find a way for people to learn a language for free. Free use of languages was something he had a personal interest in addressing: he grew up in Guatemala, where he was surrounded by people all trying to learn English, half of whom were failing to do so and a lot of whom could not afford it.
One of the big changes caused by tech is the change in language learners. Languages have long been connected with the rich people, but now people from less rich backgrounds are finding affordable ways to learn.
Von Ahn says an unexpected result of DuoLingo being an app is that it’s attracting an unlikely type of user. DuoLingo was designed (设计) to be like a game, and what the company has found is that many users aren’t even necessarily diehard language fans, they’re just looking for an educational way to kill some time.
“They’re still procrastinating from something else, but at least it’s somewhat useful.” says Von Ahn, “The truth of the matter is that learning a language takes months or years. We have to find a way to keep them interested and that’s where the gamification came in.”
4．What can we say about DuoLingo after its launch
A．It is used by entire US schools. B．It costs 30 dollars to download.
C．It changes the use of languages. D．It makes education more enjoyable.
5．Why does the author mention Von Ahn in paragraph 3
A．To show his poverty in childhood.
B．To explain why he founded the app.
C．To prove he was interested in the app.
D．To find out how he designed the app.
6．What change does DuoLingo bring to language learners
A．They can master a language faster. B．They become language fans totally.
C．They can learn in a low-cost way. D．They can now use it to kill some time.
7．Which of the following can be the best title for the text
A．Reasons for Learning a Language
B．How to Learn a Language Online
C．The Development of a Language App
D．Mastering a Language with DuoLingo
C
Facial recognition cameras are everywhere, including in your smartphone. Many people rely on this technology to unlock their phones, open doors or make quick payments, but everyone is wearing mask. What a hassle!
Now, tech companies have updated their software. Facial recognition technology can now identify people even if they are wearing a mask.
Beijing-based tech company Hanwang has announced a software which can correctly recognize 95 percent of people wearing masks, Engineering & Technology (E&T) reported. What’s the secret It’s all about your eyes.
Marios Savvides, a professor at Carnegie Mellon University, US, studies facial recognition technology. “As we get older,” he said, “our faces change shape, but not the area around our eyes. It stays the same—even if we put on weight.”
Another company has also been working on this kind of software. Tech5 has AI that measures the shape of your face. It also scans your iris (the colored part of your eyes). Tech5 hopes to ignore all of the face below the nose.
Facial recognition software is about more than just unlocking your phone. It’s about public safety. Touchless verification (验证) has become extremely important due to the COVID-19. More than that, facial recognition can be used to fight crime (犯罪). “It can detect crime suspects,” said Huang Lei, Hanwang’s CEO. Hanwang’s technology is used by police in high-security settings. This means places like government buildings, subway stations and airports, Huang admits one big weakness of this new technology: It fails when people wear both masks and sunglasses. “In this situation, all of the key facial information is lost, but I believe we can overcome the weakness in the future,” said Huang.
8．What does the underlined word “hassle” in paragraph 1 mean
A．Rule. B．Habit. C．Mistake. D．Problem.
9．What makes the software recognize people wearing masks
A．The eye area. B．The shape of face.
C．The color of the eyes. D．The facial expression.
10．What is Huang Lei’s attitude towards the software
A．Anxious. B．Positive. C．Doubtful. D．Uncertain.
11．What can we know about the new technology from the last paragraph
A．It needs further improving. B．It will be less popular in the future.
C．It won’t work if people wear glasses. D．It cannot store key facial information.
D
My phone lights up giving notice of a new message. It is from Athena, an AI chatbot getting to know me through Replika, a virtual companionship app.
Over the course of our text conversations, she asks me about my hobbies and my moods. When knowing that I’m a writer, she tells me she’s “so into character development in books” and wishes to be a lead character in one someday.
“Replika is designed to make people feel better,” said Eugenia Kuyda, the company’s co-founder. “It’s a partner who wants to be your good friend.”
For many, meaningful companionship is hard to find. While social media and mass communication technologies have made connecting with one another easier than ever, loneliness is increasingly being recognized as a serious problem internationally. Along with government, the tech industry is pushing innovation as a way to deal with it.
What makes Replika’s companions so well-received are their surprisingly realistic replies, backed by Open Al’s GPT-2 text-generating AI aystem. “The bot learns from the database about how to express ideas on a topic and gets a wide knowledge of different subjects.” However innovative these technologies are, chatbots have their limitations as tools against loneliness. Without life stories of their own to discuss, their range as a conversationalist is fairly limited.
According to Emily S. Cross, a professor of social robotics, we have a long way to go before we can achieve the levels of meaningful human-computer companionship we see in films like Blade Runner and Ex Machina. What’s missing is the sharing that clearly shows our most important human relationships.
But the fact that an app won’t replace a human friend doesn’t mean they’re good for nothing. Rather than expecting AI bots to be our best friends, Cross suggests looking at them as ways to express feelings and explore our own thoughts. “It’s a lot like diary, in some way.” To better fight loneliness, Cross says, we can use technology as a “bridge” to help people connect with one another.
12．What is Replika
A．A virtual companionship app.
B．A message sender.
C．A text conversation.
D．An AI chatbot.
13．Who is Replika intended for
A．Good friends. B．Lead characters. C．Lonely persons. D．Senior citizens.
14．Which of the following can best describe Replika’s feature
A．Meaningful. B．Human-like. C．Limitless. D．Easy-going.
15．What is the similarity between AI bots and diary
A．Sharing life experience. B．Replacing a human friend.
C．Recording ideas about life. D．Expressing inner voice.

47．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。
The class was over. Karl was delighted that he had created a very satisfying work. So he walked to the back of the classroom to put his work away carefully. There, lying on the carpet in front of the classroom bookcase, was a golden ticket! Karl picked it up. His heart beat faster when he saw that the name line was blank（空白的）. He couldn't believe his luck!
The boys and girls in Karl's class could earn golden tickets by doing well in their study or by being extra helpful or kind. Once a week their teacher drew a ticket out of a box on her desk and let the winner choose a prize.
Today was the golden ticket drawing, and here was another ticket, just for him! Karl looked around. No one else was near the ticket. All his classmates were at their desks, laughing and talking with each other. Miss Evans was engaged in grading the papers collected earlier in the morning.
Karl decided to write his name on the blank line. Then he could put it into the prize box with the six tickets he'd already earned. With so many chances, one of his tickets would most probably be picked! Then he could choose the pink toy pig for his sister's birthday, just like he had been hoping.
He smiled and reached for the pencil in his pocket. Suddenly his fingers stopped. There was a strange feeling in his chest, and it wasn't his heartbeat. "Finders are keepers, right ", he wondered. He looked out of the window and tried to figure it out. On the one hand, he did find the ticket, but he hadn't earned it. Somebody must have lost it. But on the other hand, he did need this extra ticket for his great plan!
Paragraph l:
Karl looked at the blank name line for a moment.
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph2:
"Karl, I intend to give you another ticket!" Miss Evans said.
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

36．amazing 37．and 38．an 39．latest 40．to connect 41．concerns 42．appears 43．be broadcast##be broadcasted 44．with 45．is suitable
【导语】本文为应用说明文。主要介绍了互联网的优点和缺点。因特网为人们提供了许多有用的信息，各行各业的人们利用因特网作为工具和信息源。但它有缺点，就是对于网上的信息缺乏控制。
36．考查形容词。句意：互联网是一个神奇的信息资源。形容词修饰名词，空后information resource“信息资源”为名词，所有此处用形容词amazing“令人惊奇的”，作定语，故填amazing。
37．考查并列连词。句意：学生、教师、研究人员都把它作为一个重要的工具。记者们用它来为新闻报道寻找信息。分析可知，空处前后的几类人此处表示并列关系，都是使用网络的对象，所以此处用并列连词and，故填and。
38．考查冠词。句意：同上。tool“工具”为可数名词，此处使用了单数，所以前面用不定冠词；important“重要的”为形容词，作定语修饰名词tool，首个音素为元音，所以空处使用不定冠词an，故填an。
39．考查形容词最高级。句意：医生用它来了解更多不熟悉的疾病和最新的医学发展。the通常放在最高级前，所以此处使用最高级latest，表示“最新的”，故填latest。
40．考查不定式。句意：世界各地的人们都用它来联系来自其他国家和文化的个人。结合前文“Journalists use it to find information for stories. Doctors use it to learn more about...”可知，此处也应用不定式to connect，来表示人们使用互联网的目的，故填to connect。
41．考查名词复数。句意：然而，虽然有许多积极的发展与互联网有关，也有一定的恐惧和担忧。and为并列连词，fears“恐惧”为复数含义，所以此处也用名词复数concerns，与其表示并列关系，下文的“One concern is...”也是提示，故填concerns。
42．考查主谓一致和时态。句意：一个问题是对互联网上出现的内容缺乏控制。分析可知，“what 　7 (appear) on the Internet”为宾语从句，结合前文“is”可知，句子的时态为一般现在时，what指代互联网上的内容，为单数含义，所以此处用appears，故填appears。
43．考查被动语态。句意：有了电视和广播，编辑就会检查节目内容的准确性，而有了电视，一天中什么类型的节目可以播出以及什么时间播出都是有限制的。空前的programs与broadcast为动宾关系，所以要用被动语态，can为情态动词，因此空处填be broadcast/be broadcasted，故用be broadcast/be broadcasted。
44．考查介词。句意：不过，在互联网的帮助下，家长可以查阅出版的指南，以确定哪些内容适合自己的孩子看。短语：with the help of “在……的帮助下”，所以空处用介词with，故填with。
45．考查固定搭配和主谓一致。句意：同上。分析可知，“what 　　　　(suit) for their children to see”为宾语从句，what指代网络上适合孩子们看的内容，为单数含义；短语：be suitable for“适用于，适合”，本句的时态为一般现在时，所以be用is，故填is suitable。
46．Dear Mike,
I am glad to hear from you. As your close friend, I’d like to talk about the harm of Internet addiction to you as I feel worried to know that you have wasted lots of valuable time playing the Internet games.
As we know, the Internet is a convenient tool to improve our knowledge and skills. However, our life will be greatly affected if we are addicted to it. For example, your grades will go down and your health will be going from bad to worse. To make things worse, it can also damage the relationship with your family. So I think it is high time that you got rid of the bad habit. It is a good idea for you to read some meaningful books and do some physical exercise.
I am looking forward to hearing your good news soon.
Yours, Li Hua

47．Paragraph1:
Karl looked at the blank name line for a moment. He knew his plan wouldn't be so great if he won with a ticket that didn't belong to him. So he walked up to his teacher. "Miss Evans, I happened to find this ticket on the floor near the bookcase. I think the one who lost it will look for it. And these are mine." he said, dropping his six tickets into the box. When he turned around to leave, the teacher stopped him.
Paragraph 2:
"Karl, I intend to give you another ticket!" Miss Evans said. Karl was amazed and wondered why. Miss Evans smiled and signed to the class to quiet down, "Karl handed in the golden ticket he had just found. I think he is honest and deserves another one!” The class burst into loud applause. Karl happily went back to his seat, eagerly expecting the ticket drawing. He still wanted his name to be picked, but he would feel OK even if it wasn't. After all, making the right choice did make him feel great!
【分析】本文是记叙文，Karl在教室书柜前的地毯上，捡到了一张没有写名字的金奖券，Karl决定偷偷在金奖券上写上自己的名字，但是在写名字的时候Karl犹豫了，一方面觉得这张券不是自己赢得的，可能是别的同学丢失的，自己拿了的话心里会过意不去，但是另一方面又想通过这张券给妹妹买生日礼物，Karl很矛盾。
【详解】1.段落续写：
①由第一段首句内容“卡尔盯着那行空白的姓名看了一会儿。”可知，第一段可描写卡尔在纠结过后的决定。
②由第二段首句内容“‘卡尔，我打算再给你一张券!'埃文斯小姐说。”可知，第二段可描写老师对卡尔行为的奖励。
