21、New technological tools are enabling a global community of biologists and amateur scientists to explore the natural world of sound in richer detail and at greater range than ever before. Just as microscopes helped humans observe things not visible to the naked eye, widely used microphones and machine learning models allow us to listen to sounds we cannot otherwise hear.
Billions of dollars are pouring into so-called generative artificial intelligence, such as OpenAI’s ChatGPT, with scores of new companies being launched to commercialize these foundation models. But in one sense, these models are mostly used to rearrange existing human knowledge in new combinations rather than to generate anything really new. What may have a bigger scientific impact is “additive AI”, using machine learning to explore specific, newly created data sets and extend the frontiers of human knowledge. When it comes to sonic (声音的) data, there is an incredible potential for cross-species communication through the use of machines that can translate and copy animal sounds exactly, effectively creating a “Google Translate for the zoo”.
This sonic revolution has been promoted by advances in both hardware and software. Cheap, durable, long-lasting microphones and sensors can be attached to trees in the Amazon, rocks in the Arctic or to dolphins’ backs, enabling real-time monitoring. That stream of sonic data is then processed by “additive AI”. However, this data only makes sense when combined with human observations about natural behaviors gained from painstaking fieldwork by biologists or crowdsourced analysis from amateurs.
Scientists have discovered fascinating information about the sonic universe, which has already led to practical and commercial outcomes. For example, cryptographers (密码专家) have been studying the buzzes, clicks, creaks and squeaks of whales to understand whether their “bionic Morse code” could be copied to encrypt (加密) communications. However, this is just the beginning of our exploration of sound, and there is no telling what other discoveries await us.
【1】Why does the author mention microscopes in paragraph 1?
A．To highlight the popularity of microscopes.
B．To illustrate the role of sound exploration tools.
C．To show the development of scientific instruments.
D．To stress the importance of observing beyond senses.
【2】How may “additive AI” assist in sound exploration?
A．It may make sense of natural behaviors independently.
B．It may guarantee the real-time monitoring of sonic data.
C．It may help create translation equipment for animal sounds.
D．It may help spread the existing human knowledge of sound.
【3】What’s the author’s attitude towards sound exploration?
A．Optimistic.
B．Reserved.
C．Critical.
D．Indifferent
【4】What can be the best title for the passage?

B．Sonic Translation: Inter-species Communication
C．Additive AI: Extending the Frontiers of Knowledge
D．Sonic Exploration with AI: Listening to the Unheard
22、All routes to STEM (science, technology, engineering and mathematics) degrees run through calculus (微积分) classes. Each year, thousands of college students take introductory calculus. But only a small number ultimately complete a STEM degree, and research about why students abandon such degrees suggests that traditional calculus courses are one of the reasons. With scientific understanding and innovation increasingly central to solving 21st-century problems, this loss of talent is something society can ill afford.
Math departments alone are unlikely to solve this dilemma. Several of the promising calculus reforms were spearheaded by professors outside of math departments. STEM faculty are prioritizing cooperation across disciplines to transform math classes to cultivate a diverse generation of STEM researchers and professionals.
This is not uncharted territory. In 2013, life sciences faculty at the University of California, Los Angeles, developed a two-course sequence that covers classic calculus topics, but also emphasizes their application in a biological context. Creating this course, Mathematics for Life Scientists, wasn’t easy. The life sciences faculty involved, none of whom had a joint appointment with the math department, said they turned to designing the course themselves after math faculty rejected their request for cooperation.
In Ohio, Wright State University’s Engineering departments also revised math offerings. Rather than changing the content of the calculus course, they focused on preparing students for calculus by emphasizing “engineering motivation for math.” The approach enhanced opportunities for students with weaker math backgrounds to succeed in engineering and doubled the average graduation rate of engineering students without reducing the average grade of graduates. Math learning is fundamental to all STEM fields, but the opposite also appears to be true.
【1】What problem is mentioned in paragraph 1?
A．Increasing STEM dropout rate.
B．The reform of calculus courses.
C．Shrinking admission to STEM majors.
D．The shaken belief in the role of calculus.
【2】What does “spearheaded” in paragraph 2 probably mean?
A．challenged
B．evaluated
C．cancelled
D．initiated
【3】What do we know about the calculus course reform according to the text?
A．STEM departments made calculus content easier to improve students’ grades.
B．Math departments sought cooperation with STEM counterparts to urge reforms.
C．Placing calculus learning in specific STEM contexts is a workable approach.
D．Removing calculus is the key to increasing graduation rate of STEM students.
【4】What does “the opposite” in the last paragraph refer to?
A．The STEM fields may be the foundation of other science subjects.
B．The STEM fields may be central to making math learning effective.
C．Math learning may set barrier for science study in the STEM fields.
D．Math learning may make way for science study in the STEM fields.
23、 A book is so much more than mere ink and paper. So insist French booksellers, who for nearly four decades successfully persuade the government to keep the forces of the free market at bay. A law passed in 1981 bans the sale of any book at anything other than the price decided by its publisher. Authorities are cracking down on those trying to sell the latest Thomas Piketty or J.K Rowling at a discount.
The fixed-price rule is meant to keep customers loyal to their local bookshop and out of the control of supermarkets and corporations. But the arrival of e-commerce and e-readers has promoted questions worthy of their own tomes(大部头著作). Can you fix the price of a book if it is part of an all-you-can-read subscription service? Are audio-books books at all? And what of authors who self-publish?
Changes have been made to preserve the principle of “one book, one price”. In 2011, the rule began to apply to digital tomes. Free delivery by online sellers was prohibited because it implied a subsidy(补贴) on the delivered books (encouraging online sellers to charge only €0.01 for postage). But a new challenge to the policy is proving more difficult to deal with.
Used books are exempted from the pricing rule. Third-party sellers on Amazon are accused of using this as a way to apply forbidden discounts: selling brand-new books as “second hand” to make them cheaper. So fans can purchase a copy of the latest Michel Houellebecq novel Serotonine for 11.71 pounds on Amazon, roughly half of its original price. Its seller claims it is in “perfectly new” condition.
Amazon claims its practices are legal. But books sellers are upset, and their political allies with them. “This is a major concern,” said Franck Riester, the culture minister, at a bookseller’s conference this week. He says new laws may be needed.
Defenders of the fixed-price principle (which has spread to other parts of Europe) say it helps keep independent bookshops alive. Others are not so sure. Books are expensive in France — an odd way to encourage people to buy more.
【1】What was the function of the law passed in 1981?
A.To stop publishers from publishing poor books.
B.To prevent the random price of books in the market.
C.To help book consumers benefit from the free market.
D.To encourage French booksellers to sell cheaper books.
【2】What’s implied about the arrival of e-commerce and e-readers in Paragraph 2?
A.It greatly changed people’s reading habits.
B.It challenged the principle of “one book, one price”.
C.It weakened the ties between publishers and authors.
D.It provided local booksellers with some new opportunities.
【3】What does the underlined part “are exempted from” in Paragraph 4 mean?
A.are involved in. B.are threatened by.
C.are consistent with. D.are unrestricted by.
【4】What is Franck Riester’s attitude towards those third-party sellers’ practices on Amazon?
A.He is hopeful of them. B.He is uncertain of them.
C.He disapproves of them. D.He is indifferent to them.
24、 These animal dads have some seriously strange ideas about fatherhood.
Barbary macaque
Unlike human dads boasting of their kids' winning contests or college acceptances, barbary macaques, monkeys that are native to North Africa, show off babies as a way to impress each other and build social networks. These monkeys live in troops of about 30 members, and life centers around the babies born each spring.
During baby season, males carry the infants, even picking up little ones that aren’t their own offspring (后代). However, there are status symbols, used to build male social networks and connections within the group. The infants can serve as a social passport, to approach other males and hang out with them. After all, it’s much simpler to break the ice if you have a cute baby in hand.
Sand grouse
Lots of dads bring home the bacon. But for young sand grouses living in Namibia’s dry deserts, water is the essential resource. Sand grouse fathers are the frequent flyers that travel almost 125 miles each day to fill up for the family at a watering hole.
With no other way to transport water, male sand grouses settle in the pool, rocking back and forth to bathe their belly feathers. Filling up can take 15 minutes, leaving them exposed to killers like falcons (猎鹰). But it all pays off. The dads return home after a long day and are able to provide their babies with few precious tablespoons of liquid.
Pipefish
Pregnant pipefish males-yes, males-give birth to live young from eggs that females deposit in their brood pouches (育儿袋). This mothering act has earned them praise as devoted animal dads.
But it turns out that the pregnant pipefish also has a wandering eye. If he sees a bigger female he often aborts (流产) existing eggs. If he stops exporting nutrients to the developing embryos (胚胎) while reabsorbing nutrients from abortions, he assures enough resources to invest in the more rewarding offspring.
Blue poison dart frog
Females of this species lay only about half a dozen precious eggs. That is maybe why dads are so devoted to them. Frog eggs must stay watery or moist, and these devoted dads accomplish that by regularly urinating on them over the course of 10 days, until they hatch (孵化) as tadpoles.
【1】Barbary macaques carry their kids around in order to _____.
A．show how proud they are about being a father.
B．show their family strength within monkey groups.
C．center around their kids as a tradition.
D．build up better relations with other monkeys.
【2】The resource of water or liquid is precious to _____.
A．barbary macaque and sand grouse.
B．sand grouse and pipefish.
C．pipefish and blue poison dart frog.
D．sand grouse and blue poison dart frog.
【3】Which of the following statements is TRUE?
A．Sand grouse carries the water by drinking it first and then spitting it out.
B．Pipefish gives up some eggs in order to make himself stronger.
C．Male blue poison dart frog protects the eggs by keeping them wet.
D．Sand grouse has to compete for water with the falcon.
25、Jeff Jensen was suffering from painful nerve damage in his leg and foot. He needed surgery, but he doubted if he could ___________it, even with insurance. “There’s nothing more ___________than seeing a bill for 18, 20, 24,000 dollars and going,” said Jensen.
Luckily for Jensen, his doctor is Demetrio Aguila. The nerve specialist gives patients at his Healing Hands of Nebraska in Papillion the_______to pay for surgery through community service instead of money. He calls it M25 Program. At the heart of his vision was the simple_______ of people helping people.
Using an algorithm (算法) , the clinic calculates community service hours based on the price of the surgery. In Jensen’s case, the $12,000 operation equaled 560 hours of_________at one of the local charitable organizations registered with the M25 Program. Jensen opted for the community service. Since hundreds of hours of community service would be_______, Aguila encouraged others to help, and he_______involved himself in it. “I had this hope that we would rekindle (重新激起) the enthusiasm for _________________in our neighbors and in ourselves,” he told CNN.
Jensen, whose surgery was completed in February 2020, was helped by more than 100 friends and strangers who freely offered to help at Orphan Grain Train, which donates food, clothing, and medicine nationally and globally.
