21、With the World Cup always held in the European off-season in June and July, when the tiny nation of Qatar beat out USA Australia, Japan and South Korea, as the venue（地点）of the 2022 World Cup Soccer, there were gasps of surprise from the fans – it was not just because of the size of the competitors, but also the fact that Doha sees an average top temperature of 41 degrees Celsius in June and July with the possibility of top temperatures as high as 50°C.
Since the World Cup cannot be moved to the ‘cooler’ season in January or to a neighboring country with milder weather, Qatar has to figure out a solution to make the game more comfortable. A team of engineering scientists from Qatar University (QU) have taken a more high-tech approach to solving the problem – they've reportedly developed a type of artificial "cloud" designed to float above the World Cup venues and provide fans and players with relief from the blazing sun.
The artificial clouds system was invented by a team led by Dr Saul Abdul Ghani, Head of the Mechanical and Industrial Engineering Department at QU, who told Gulf News that the "clouds" would be made from a lightweight carbon structure carrying a giant envelope of material containing helium（氦）gas. The "cloud" would also feature solar panels on its upper surface to power engines that allow the cloud to be moved via remote control. While the country officials have promised to improve some of the issues with solar-powered stadiums capable of reducing the temperatures inside, to a comfortable 20℃, there is still concern of how the players will be able to function in the practice fields.
The system would initially cost around US$500,000, with prices coming down with commercial scale production. However, since Qatar needs to find a solution, the money is probably to the issue. The bigger question is, will this team of scientists actually be able to conjure up（兑现）something that they have promised? We will all find out in about eleven years!

22、Despite the huge potential of artificial intelligence (AI), it hasn’t caught hold in most industries. Sure, it has transformed Internet companies such as Google, Baidu, and Amazon—all massive and data-rich with hundreds of millions of users. But for expectations that AI will create $13 trillion of value a year to come true, industries such as manufacturing, agriculture, and healthcare still need to find ways to make this technology work for them. Here’s the problem: The script (程序脚本) that these Internet companies use to build their AI systems—where a single one-size-fits-all AI system can serve massive numbers of users—won’t work for these other industries like mentioned above.
Instead, these huge industries will need a large number of custom-built solutions that are adapted to their many diverse use cases. This doesn’t mean that AI won’t work for these industries, however. It just means they need to take a different approach.
To bridge this gap and release AI’s full potential, leaders in all industries should adopt a new, data-centered approach to building AI. Specifically, they should aim to build AI systems with careful attention to ensuring that the data clearly conveys what they need the AI to learn. This requires focusing on data that covers important cases and is constantly labelled, so that the AI can learn from this data what it is supposed to do. In other words, the key to creating these valuable AI systems is that we need teams that can program with data rather than program with code. The data-centered approach to AI, supported by tools designed for building, using, and maintaining AI applications—called machine learning operations (MLOps) platforms—will make AI’s full potential possible. Companies that adopt this approach faster will have a leg up relative to competitors.
Just as electricity has transformed every industry, AI is on a path to do so too. Specifically, a new data-centered approach, coupled with MLOps tools that allow industry domain experts to participate in the creating, using and maintaining of A I systems, will ensure that all industries can get the rewards that AI can offer.
【1】Why do some industries still need to find ways to make AI work for them?
A．AI technology needs hundreds of millions of users.
B．Internet companies such as Amazon have transformed AI.
C．The potential of AI has caught hold in most industries so far.
D．The script of Internet companies can’t suit all industries.
【2】What is the author’s attitude to the prospect of AI’s application to all industries?
A．Positive.
B．Doubtful.
C．Unclear.
D．Intolerant.
【3】What will contribute to realizing AI’s full potential?
A．Leaders in all industries.
B．Program learning with code.
C．Machine learning operations.
D．Concepts clearly illustrated，
【4】What does the last paragraph mainly talk about concerning AI?
A．AI and Electricity are of equal importance.
B．AI is closely related to industry domain experts.
C．AI will need electricity to completely transform every industry.
D．AI will benefit all industries through the data-centered approach.
23、Determined to make school more related to the workplace, Roosevelt High School in Portland, Oregon, developed a school-to-work program. In their first year, students are offered some job pathways in natural resources, human services, health care, business, arts and communication. The following year, each student chooses one of the pathways and examines it in depth, spending three hours a week watching someone on the job. Such a program is also in practice in some other states.
The school-to-work program is built around a partnership. For example, Eastman Kodak, a major employer in Colorado, introduces students to business by helping them construct a model city using small pieces of wood. “The children use the models to decide on the best place to set up schools,” says Lucille Mantelli, director for Eastman Kodak in Colorado. Kodak introduces math by teaching fifth graders to use their pocket money properly. They also provide one-on-one job watching experiences and offer chances of practice for high school juniors and seniors. “Students come to the workplace two or three hours a week,” explains Mantelli. “They do the job for us. We pay them and they get school credits (学分). We also give them our views on their performance and developmental opportunities.”
In these partnerships, everybody wins. The students tend to take more difficult courses than students in schools that don’t offer such programs. Business benefits by having a better prepared workforce needed in future years. “It’s a way for us to work with the school systems to develop the type of workforce we’ll need in future years,” Mantelli continued. “We need employees who understand the basics of reading and writing. We need them to be good at math and to be comfortable working on a team.”
“Our theory is that they can learn as much outside the classroom as in. All students have the ability to change the world, not just to live in it. To do that, they have to know how to solve problems and use critical thinking skills. We need to encourage them to dream about jobs that go beyond what they see today,” concludes a school-to-work program organizer.
【1】Using the example of Eastman Kodak in Colorado, the writer shows us ____.
A. what role the business plays in the program
B. why the students get paid for their jobs
C. where the students have their math class
D. what the school decides to do
【2】The main purpose of the school-to-work program is to _____.
A. make what students learn in school related to the workplace
B. introduce new job opportunities to schools
C. improve relations between students and teachers
D. offer students more difficult courses
【3】According to the text, Lucille Mantelli is ____.
A. a math teacher
B. a company manager
C. a school designer
D. a program organizer
24、Have you ever imagined traveling to a foreign country without having to worry about the headache of communicating in a different language?
In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within a decade or so, we’ll be able to communicate with one another via small earpieces with built - in microphones. That’s because technological progress is extremely rapid. It’s only a matter of time. Indeed, some parents firmly hold the idea that this technology is approaching and they’re wondering if their kids should even learn a second language.
It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It’s not good to sleep too much.” Replacing a word with its equivalent (同义词) in the target language is actually the “easy part” of a translator’s job. But even this seems to be a discouraging task for computers.
It’s so difficult for computers because translation doesn’t--or shouldn’t--involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.
Think about all the related clues that go into understanding an expression：volume，gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.
Therefore, we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.
【1】What view does the author hold about translation?
A．Proper translation can be tough for humans.
B．Slight differences matter little in translation.
C．Some machines will interpret our world properly.
D．Cultures deserve more attention than words used.
【2】What is the best title for the text?
A．An Expert’s Precise Prediction
B．The Complexity of Translation
C．Who Will Be a Better Translator
D．Will Language Barrier Actually Disappear?
【3】What is the author’s attitude to the modern technology?
A．Unclear
B．Objective
C．Optimistic
D．Negative.
【4】In which column can you read the article in a newspaper?
A．Language Learning.
B．Comments on hot issues.
C．Science Development.
D．Translation tips.
