21、One night, a seriously injured patient was transferred to hospital in Nanjing, Jiangsu, from Anhui province. The patient was hearing-impaired, so it was difficult for medical workers to communicate with him.
At the same time, Chen Xin was studying at the library. He is a senior student of architectural engineering technology in Nanjing Polytechnic Institute. The 20-year-old is also a sign language interpreter. He immediately rushed to the hospital, which is next to his college, after receiving an urgent call. Chen helped the patient communicate with medical staff until the patient was released from the hospital.
“In many cases, some hearing-impaired people have to delay seeking medical treatment for various reasons, which brings health risks and property losses to the group,” said Chen.
Chen knew some deaf friends, but they can only communicate with each other by typing on the mobile phone. This encouraged Chen to learn sign language. In 2018, Chen, then a senior high school student, attended a program by Nanjing Normal University of Special Education to learn from professionals and was certified (认证) as a sign language interpreter.
“Finger flexibility is a key,” Chen said,“I couldn’t make precisely harmonious movements of my fingers at first.” So Chen took part in activities for deaf people to practice more.
Every kind of language has its own grammar system. So does sign language, “Its word order is different from Chinese or English,” Chen said. For example, if you want to say “I love you”, you need to sign “I you love”. “I spent a lot of time getting used to such differences,” Chen said.
After mastering sign language, Chen built close relationships with hearing impaired people and offered to help them.“Many of them turn to me when they go to see a doctor," Chen said.
Recalling another volunteer experience, Chen said he was very nervous at that time. “We knew little about COVID-19 in February 2020. I was wondering how to explain the virus,” Chen said,“I was afraid of mistakenly translating the term.”
After his graduation, Chen plans to be a professional sign language interpreter and offer services for more hearing impaired people.
【1】What inspired Chen to learn sign language?
A．A medical emergency he suffered.
B．A program related to sign language.
C．The support from some professionals.
D．The way his deaf friends communicate.
【2】What was a problem facing Chen after mastering sign language?
A．He often confused the gestures of words.
B．He had trouble explaining some concepts.
C．He found it difficult to memorize the gestures.
D．He had to improve his finger flexibility.
【3】Which of the following can best describe Chen?
A．Creative and patient.
B．Humorous and tough.
C．Warm-hearted and thoughtful.
D．Talented and modest.
【4】Which do you think is the best title of the passage?
A．Lending helping hands
B．Becoming an interpreter
C．Learning sign language
D．Offering services to people

23、 Richard Holmes, a British author and academic, is something of a Romantic, famous for biographies of Percy Bysshe Shelley and Samuel Taylor Coleridge. In his last book, "The Age of Wonder"， he wrote about science and Romanticism and their common commitment to discovery. In his new book, "Falling Upwards"， he combines the two again to tell the stories of Europe's early balloonists (气球飞行者).
Mr Holmes's love of balloons was aroused at a village festival and his enthusiasm is one of the book's many pleasures. He refers to the cheerful tone used in many first-hand ballooning stories, and applies it in this second-hand account. He describes men and women wrapped up in fur coats under their hydrogen-filled balloons, enjoying cold chicken and champagne and looking back to earth to see mankind "for what it really is."
Mr Holmes makes much of the strange side of ballooning, but the book is at its best when examining its more serious applications. In the American civil war, for example, both North and South put observers in balloons to spy on enemy movements. And during the Prussian attack on Paris in 1870-71， balloonists managed to fly out of the city to communicate with the French government in exile (流亡) in Tours.
"Falling Upwards" contains much of the historian's writing characteristics, such as footnotes and bibliography (文献书目)， but its epilogue (后记) refers modestly to what has gone before as "a series of true balloon stories". It does touch on the more technical aspects of ballooning, and says little about the French Montgolfier brothers who are credited as its inventors. That though seems a small price to pay for such a spirited work. Mr Holmes's tale ends at the start of the 20th century when the business of flight was being handed over to the airship and the airplane.
【1】In his book "Falling Upwards"， Richard Holmes ______ .
A.uses the similar writing style of "The Age of Wonder"
B.describes how people celebrated a village festival
C.gives first-hand accounts of Europe's early balloonists
D.discusses balloons used in war in a serious tone
【2】The highlight of Falling Upwards lies in ______ .
A.its vivid descriptions of balloonists' life
B.its analyses of the serious uses of balloons
C.its reference to many historical resources
D.its research on the ballooning technology
【3】What does the underlined sentence in paragraph 4 mean？ ______
A.Falling Upwards is an inspiring book but its price is a little high.
B.To complete the book, Holmes received Montgolfier brothers' financial aid.
C.It is a pity that the book doesn't introduce Montgolfier brothers in detail.
D.It actually didn't take Holmes much work to write such a good book.
24、 Classifying things is critical for our daily lives. For example, we have to detect spam mail (垃圾邮件), false political news. When we use AI, such tasks are based on “classification technology” in machine learning—having the computer learn, using the boundary separating positive and negative data. For example, “positive” data would be photos including a happy face, and “negative” data photos that include a sad face. Once a classification boundary is learned, the computer can determine whether a certain data is positive or negative.
However, the difficulty with this technology is that it requires both positive and negative data for the learning process, and negative data are not available in many cases. For instance, when a retailer (零售商) is trying to predict who will make a purchase, they can easily find data on customers who have purchased from them (positive data), but it is basically impossible to obtain data on customers who have never purchased from them (negative data), since they do not have access to their competitors’ data.
According to lead author Takashi Ishida from RIKEN AIP, “Previous classification methods could not cope with the situation where negative data were not available, but we have made it possible for computers to learn with only positive data, as long as we have a confidence score for our positive data, constructed from information such as buying intention or the active rate of app users. Using our new method, we can let computers learn a classifier only from positive data equipped with confidence.”
According to Ishida, “This discovery could expand the range of applications where classification technology can be used. Even in fields where machine learning has been actively used, our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints (限制). In the near future, we hope to put our technology to use in various research fields, such as natural language processing, computer vision, robotics, and bioinformatics.”
【1】How can the computer distinguish the positive data from the negative data?
A.By learning the classification boundary.
B.By updating the data collected regularly.
C.By separating happy faces and sad ones.
D.By introducing classification technology.
【2】Why is the example mentioned in Paragraph 2?
A.To prove how important the positive data are.
B.To confirm that data on customers are complete.
C.To argue that retailers get their competitors’ data.
D.To explain why negative data are hard to acquire.
【3】What do the underlined words “new method” in Paragraph 3 refer to?
A.Analyzing buying intention.
B.Building a confidence score.
C.Assessing the active rate of app users.
D.Equipping the computer with confidence.
【4】What can be a suitable title for the text?
A.The History of Classification Technology
B.Smarter AI: Machine Leaning without Negative Data
C.Bigger Data: Computers Assisting Language Processing
D.The Comparison between Positive Data and Negative Data

26、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。
Tess was a precocious (早熟的) eight-year-old girl when she heard her parents talking about her little brother, Andrew. All she knew was that he was very sick and they were completely out of money to cover the doctor’s bills.
Only a very costly surgery could save him now and it was looking like there was no one to loan them the money. She heard Daddy say to her tearful Mother with whispered desperation，“Only a miracle can save him now.”
Tess went to her bedroom and pulled a glass jelly jar and poured all the change out on the floor and counted it carefully. Then she slipped out the back door with all her money and made her way 6 blocks to Rexall’s Drug Store.
She waited patiently for the pharmacist to give her some attention but he was too busy at this moment. Tess twisted her feet to make a noise. Nothing. She cleared her throat with the most disgusting sound she could muster.
No good. Finally she took a quarter from her jar and banged it on the glass counter. That did it! “And what do you want?” the pharmacist asked in an annoyed tone of voice. “I'm talking to my brother from Chicago whom I haven’t seen in ages.” he said without waiting for a reply to his question.
“Well, I want to talk to you about my brother,” Tess answered back in the same annoyed tone. “He’s really, really sick and I want to buy a miracle.” “I beg your pardon?” said the pharmacist. “His name is Andrew and he has something bad growing inside his head and my Daddy says only a miracle can save him now. So how much does a miracle cost?” “We don’t sell miracles here，little girl. I'm sorry but I can’t help you,” the pharmacist answered impatiently.
