21、“Is it art?” Tyka, an artist and software engineer, asked the audience at Christie's 2019 Art + Tech Summit in New York in June 2019. The event's theme was “The A. I. Revolution”, and Tyka was referring to artwork created using artificial intelligence. He flashed an image of urinal (小便池) on two large screens at either side of the stage —Marcel Duchamp's famous and controversial sculpture Fountain. The audience laughed. “Obviously, it can be,” he said.
However, many in the art community are wrestling with several unanswered questions after an algorithm-produced (演算法) print that resembled 19th century European portraits was sold for $432, 500. For example: when artwork is accomplished by means of the algorithm, who is the artist—the programmer or the computer? Because many works of AI art are digital, how do you value a creation that's designed to live natively on the Internet and be widely shared? There are few clear answers.
Claire Marmion, the founder and CEO of Haven Art Group, says collectors are still trying to figure out where the market for AI art is heading, and that it may not be the disruptive (破坏性的) force that some think it will be. Or, at least, the industry will adapt to it.
Mario Klingemann, whose work was sold by Sotheby's, prefers the term “generative art”, which includes all works created using algorithms, and believes the current buzz will eventually die down, otherwise AI art isn't going anywhere. Instead, he thinks it will one day be viewed as simply another tool of the artist.
“Just like photography never goes away, or making movies doesn't, I'm pretty sure it will establish itself as a new media format,” he says. “Right now, of course, it's all this mystery about AI, but I expect this to become really just a normal thing, where people will focus on what artists are actually saying with their art.”
【1】What's the function of the first paragraph?
A.To show what art is.
B.To entertain readers.
C.To explain the event's theme.
D.To lead to the topic of the passage.
【2】What makes people in the art industry feel confused?
A.Who is the real creator of a piece of AI artwork.
B.Where people can by AI artwork.
C.How to sell AI artwork at a high price.
D.How to share AI artwork.
【3】Which can best explain the underlined word “buzz” in the fourth paragraph?
A.Excitement.
B.Objection.
C.Revolution.
D.Argument.
【4】What does Klingermann think about AI art?
A.Its future is unclear.
B.It will disturb the traditional art industry.
C.It will be as common as photography and movies.
D.It will be applied to photography and film industry.
22、Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children’s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging.
Scientists measured this by studying the ends of children’s chromosomes(染色体), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.
Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.
Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.
In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner; physical maltreatment by an adult; or bullying. Researchers measured the children’s telomeres—in cells obtained by swabbing the insides of their cheeks—at ages 5 and 10.
Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.
Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.
He study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

24、Identifying common bird species through their song has never been easier, with numerous phone apps and software available to both ecologists and the public. But what if the identification software has never heard a particular bird before, or only has a small sample of recordings to reference? This is a problem facing ecologists and conservationists monitoring some of the world’s rarest birds.
To overcome this problem, researchers at the University of Moncton, Canada, have developed ECOGEN, a first-of-its-kind deep learning tool that can generate life-like bird sounds to enhance the samples of under-represented species. These can then be used to train audio identification tools used in ecological monitoring.
The researchers found that adding artificial bird song samples generated by ECOGEN to a bird song identifier improved the bird song classification accuracy by 12% on average.
Dr. Nicolas Lecomte, one of the lead researchers, said: “Due to significant global changes in animal populations, there is an urgent need for autonomous tools, such as acoustic monitoring, to track shifts in biodiversity. However, the Al models used to identify species in acoustic monitoring lack comprehensive reference libraries.” With ECOGEN, you can address this gap by creating new instances of bird sounds to support AI models.
The researchers say that creating bird songs in this way can contribute to the conservation of endangered bird species and also provide valuable insight into their vocalisations, behaviours and habitat preferences. The ECOGEN tool can also be used to help conserve extremely rare species. For instance, it could be used to help conserve the critically endangered regent honeyeaters (摄政蜜鸟), from which young individuals are unable to learn their species’ songs because there aren’t enough adult birds to learn from.
The tool could benefit other types of animal as well. Dr. Lecomte added, “While ECOGEN was developed for birds, we’re confident that it could be applied to mammals, fish, insects and amphibians.”
As well as its versatility, a key advantage of the ECOGEN tool is its accessibility, due to it being open source and able to be used on even basic computers.
【1】What is the newly developed ECOGEN tool used to do?
A.Identify bird species through songs.
B.Record sounds of bird species in nature.
C.Compare common bird species with rare ones.
D.Produce bird songs to train bird identification tools.

D.The dramatic changes in biodiversity.
【3】Why were regent honeyeaters mentioned?
A.To show the dangerous situation of these birds.
B.To give a successful example of conservation.
C.To raise people’s awareness of rare bird species.
D.To point out the application of the ECOGEN tool.
【4】What does the underlined word “versatility” in the last paragraph mean?

C.Flexibility.
D.Stability.
25、Biodiversity is a concept that's commonly referenced, yet regularly misunderstood. The complex_______ not only refers to the unbelievable variety of life on Earth, but to how everything from genes to entire ecosystems interact to make the planet habitable. The bad news: science shows that biodiversity is _______ worldwide at a faster rate than at any time in human history. That’s obviously devastating for everything in nature--including us.
“If biodiversity disappears, so do people,” says Dr. Stephen Woodley, field ecologist and bio-diversity expert with the International Union for Conservation of Nature. “We are part of the _______ and we do not exist without it.”
Preventing such a catastrophe, says Woodley, begins with understanding why biodiversity is declining, and then taking action to _______ course.
“The two greatest _______ of biodiversity loss are habitat loss, primarily on land, and overexploitation, primarily in the ocean,” Woodley says. He explains that we can solve these problems by permanently _______ more lands and oceans and managing them for their conservation values.
That's the mission of the global Campaign for Nature, a partnership of the Wyss Foundation and the National Geographic Society. Instead of simply protecting 30 percent of the Earth, the_______ also encourages nations, in full partnership with local communities, to focus on the right 30 percent. Those areas, says Woodley, _______ the most important biodiversity, such as endangered species and ecosystems and rare species and ecosystems.
The campaign also recognizes the importance of_______ local rights. Local peoples manage or hold tenure(保有权) over lands that support about 80 percent of the world's biodiversity, making it ________ for these communities to be full partners in developing and implementing strategies.
________, protecting the health of key biodiversity areas is vital for tackling climate change, says National Geographic Explorer-in-Residence Dr. Enric Sala. Pairing the international Paris Agreement to combat climate change, Sala's paper asserts, “would ________catastrophic(灾难性的) climate change, conserve species, and secure essential ecosystem services.”
“Biodiversity is stability,” says Sala. “Trees, wetlands, grasslands, peat bogs(泥炭沼泽), salt marshes(盐沼), healthy ocean ecosystems, mangroves(红树林), and plants ________ much of the carbon pollution humans put into the atmosphere. Yet, right now, less than half of the planet is in its natural state, which isn't enough.” Bottom line: Nature needs us to act-now. “Moving to Mars is not a(n) ________,” Sala adds. “The only conditions for our life and for the prosperity of human society are here on Earth ...we are ________ protecting it.”

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。
It's getting hot. It's time to put on lighter clothes and open up the windows. I can't wait to do so. Yesterday, an unforeseen visit to the kitchen happened during the brief time we were out. Two daring sparrows (麻雀) had risked landing on our territory to enjoy the freshness in our sink and some other breadcrumbs (面包屑) on our kitchen counter.
Actually, sparrows are everywhere. The tiny, gray -and brown birds are found on every continent except Antarctica, flying or jumping around cities, picking up leftover food on side-walks, and sometimes chasing with native bird species. These small creatures have adapted to living alongside humans- similar to pet dogs.
When you come across such sudden callers, you are likely to sense it as an unwanted visitor into your comfort zone, or you might receive it as a lovely angel of life. I chose the second option, with no hesitation while my husband preferred driving them away. After all, I've never come to stop to feel the relationship with sparrows.
I recalled when I was a little girl living in the city, I lived in an apartment with a flat roof viewed from our kitchen window. Every day my mom and I would go out to feed the sparrows. She taught me how to call them with a clicking sound she made with her tongue. I have loved sparrows ever since. So every day in my spare time, I can't stop observing and celebrating their dance from our window. I stuffed them with the leftovers on our tablecloth after every meal. And I have provided them with every kind of bases and stands of our house.
Undoubtedly, they feel at ease in our backyard. And that has led them to gather up courage and slide into our kitchen, bedroom or even reading room. Perhaps because they have the feeling that we don' t consider them trouble makers, but friendly neighbors. But I am slightly worried about their droppings (粪便).
注意:
