Jorg Muller, an ecologist at the University of Würzburg, with his colleagues, proposes a way to measure the biodiversity—listen to the jungle by AI, in a paper published in Nature Communications.
The rainforests are very important and always alive with the sounds of animals, which is useful to ecologists. When it comes to measuring the biodiversity of a piece of land, listening out for animal caller is more effective than uncovering the bushes looking for tracks and paw prints. The latter analysis method is time-consuming, and it requires an expert pair of ears. Muller’s idea was to apply the principle of smartphone apps which can identify the sounds of birds, bats and mammals to conservation work.
The researchers took recordings from across 43 sites in the rainforests. Some sites were relatively primitive, old-growth forests. Others were areas that had just been cleared for pasture(牧场) recently. And some other original forests had been cleared but then abandoned, allowing themselves to regrow. The various calls were identified by an expert,and then used to construct a list of the species present. As expected, the longer the land had been free from agricultural activity, the greater biodiversity it hosted. Then it was the computer’s turn. “We found that the AI tools could identify the sounds as well as the experts,” says Dr. Muller.
Of course, not everything in a rainforest makes a noise. Dr. Muller and his colleagues used light traps to catch night-flying insects, and DNA analysis to identify them. They found that the diversity of noisy animals was a reliable representative for the diversity of the quieter ones, too.
Besides measuring the biodiversity, the results are also expected to be applied to outside ecology departments. Under pressure from their customers, firms like L’Oreal, a make-up company, and Shell, an oil firm, have been spending money on forest restoration projects around the world. Dr. Muller hopes that an automated approach to checking on the results could help monitor such efforts, and give a standard way to measure whether they are working as well as their sponsors say.
1．Why does Muller propose to measure biodiversity with AI

1．细节理解题。根据第二段中“When it comes to measuring the biodiversity of a piece of land, listening out for animal caller is more effective than uncovering the bushes looking for tracks and paw prints. The latter analysis method is time-consuming, and it requires an expert pair of ears.”（在测量一块土地的生物多样性时，倾听动物的叫声比揭开灌木丛寻找足迹和爪印更有效。后一种分析方法耗时长，需要一双专家的耳朵。）可知，穆勒提出用人工智能来衡量生物多样性是因为比人力更有效率地工作。故选C项。
2．细节理解题。根据第三段中““We found that the AI tools could identify the sounds as well as the experts,” says Dr. Muller.”（“我们发现人工智能工具可以像专家一样识别声音，”穆勒博士说。）可知，人工智能工具可以像专家一样辨认出不同物种的声音。故选A项。
3．推理判断题。根据第四段中“They found that the diversity of noisy animals was a reliable representative for the diversity of the quieter ones, too.”（他们发现，嘈杂动物的多样性也是安静动物多样性的可靠代表。）可推知，作者在第4段指出安静的动物和嘈杂的动物一样具有多样性。故选B项。
4．推理判断题。根据最后一段中“Dr. Muller hopes that an automated approach to checking on the results could help monitor such efforts, and give a standard way to measure whether they are working as well as their sponsors say.”（穆勒博士希望一种自动检查结果的方法可以帮助监督这些努力，并提供一种标准方法来衡量它们是否像赞助商所说的那样有效。）可知，从最后一段可以推断出这项研究将有助于森林恢复。故选C项。
B
Flinging brightly coloured objects around a screen at high speed is not what computers’ central processing units were designed for. So manufacturers of arcade machines invented the graphics-processing unit (GPU), a set of circuits to handle video games’ visuals in parallel to the work done by the central processor. The GPU’s ability to speed up complex tasks has since found wider uses: video editing, cryptocurrency mining and most recently, the training of artificial intelligence.
AI is now disrupting the industry that helped bring it into being. Every part of entertainment stands to be affected by generative AI, which digests inputs of text, image, audio or video to create new outputs of the same. But the games business will change the most, argues Andreessen Horowitz, a venture-capital (VC) firm. Games interactivity requires them to be stuffed with laboriously designed content: consider the 30 square miles of landscape or 60 hours of music in “Red Dead Redemption 2”, a recent cowboy adventure. Enlisting AI assistants to churn it out could drastically shrink timescales and budgets.
AI represents an “explosion of opportunity” and could drastically change the landscape of game development. Making a game is already easier than it was: nearly 13,000 titles were published last year on Steam, a games platform, almost double the number in 2017. Gaming may soon resemble the music and video industries in which most new content on Spotify or YouTube is user-generated. One games executive predicts that small firms will be the quickest to work out what new genres are made possible by AI. Last month Raja Koduri, an executive at Intel, left the chip maker to found an AI-gaming startup.
Don’t count the big studios out, though. If they can release half a dozen high-quality titles a year instead of a couple, it might chip away at the hit-driven nature of their business, says Josh Chapman of Konvoy, a gaming focused VC firm. A world of more choices also favors those with big marketing budgets. And the giants may have better answers to the mounting copyright questions around AI. If generative models have to be trained on data to which the developer has the rights, those with big back-catalogues will be better placed than startups. Trent Kaniuga, an artist who has worked on games like “Fortnite”, said last month that several clients had updated their contracts to ban AI-generated art.
If the lawyers don’t intervene, unions might. Studios diplomatically refer to AI assistants as “co-pilots”, not replacements for humans.
5．The original purpose behind the invention of the graphics-processing unit (GPU) was to ________.
A．speed up complex tasks in video editing and cryptocurrency mining
B．assist in the developing and training of artificial intelligence
C．disrupt the industry and create new outputs using generative AI

Enlisting AI assistants to churn it out could drastically shrink timescales and budgets. (游戏的互动性要求它们充满精心设计的内容：想想最近的牛仔冒险游戏《荒野大镖客2》中30平方英里的风景或60小时的音乐。招募人工智能助手来制作它可以大大缩短时间和预算)”可推知，游戏领域的人工智能有望简化游戏开发过程，节省大量的的时间和投入。故选B项。

C
Artificial intelligence is almost twice as accurate as a biopsy (活组织检查) at judging the aggressiveness of some cancers, experts say. Cancer kills 10 million people globally every year, according to the WHO. But for patients the disease can be prevented if detected instantly and dealt with quickly.
A recent study suggested an AI algorithm (算法) was far better than a biopsy at correctly grading the aggressiveness of sarcomas (肉瘤), a rare form of cancer. Researchers hope AI will improve outcomes for patients by giving doctors a more accurate way of grading tumours (肿瘤). Because high-grade tumours can indicate aggressive disease, the tool could help ensure those high-risk patients are identified more quickly and treated instantly. Low-risk patients could also be spared unnecessary treatments, follow-up scans and hospital visits.
Researchers say the algorithm could be applied to other types of cancer in future. The team specifically looked at retroperitoneal sarcomas, which develop at the back of the abdomen and are difficult to diagnose (诊断) and treat due to their location. They used CT scans from 170 patients with the two most common forms of retroperitoneal sarcoma — leiomyosarcoma and liposarcoma. Using data from these scans they created an AI algorithm, which was then tested on 89 patients in other countries. In grading how aggressive the tumour was, the technology was accurate in 82% of the cases, while biopsies were 44%.
AI could also recognize leiomyosarcoma and liposarcoma in 84% of sarcomas tested, while radiologists were able to identify them in 65% of the cases. Christina Messiou, the study leader, said: “We’re incredibly excited by the potential of this state-of-the-art technology, which could lead to patients having better outcomes through faster diagnosis. As patients with retroperitoneal sarcoma are routinely scanned with CT, we hope this tool will eventually be used globally, ensuring that not just specialist centres can reliably identify and grade the disease.”
Richard Davison, chief executive of Sarcoma UK, said the results looked “very promising”. He added: “People are more likely to survive sarcoma if diagnosed early. One in six people with sarcoma cancer wait more than a year to receive an accurate diagnosis, so any research that helps patients receive better treatment and support is welcome.”
9．According to the passage, AI is capable of ____ .
A．grading the risk of sarcomas
B．measuring the scale of sarcomas
C．providing cancer treatment for clinicians
D．classifying cancers with its advanced algorithm
10．What can be inferred from this passage
A．More sarcomas can be detected with the help of AI.
B．Biopsies will be replaced by AI algorithm in identifying cancers.
C．More patients suffering from cancers will benefit from AI algorithm.
D．AI algorithm has been applied in hospitals for detecting most cancers.
11．What is the passage mainly about
A．AI has a profound market in curing cancers.
B．New treatments for sarcomas are well underway.
C．AI helps identify high-risk and low-risk patients.
D．AI does better in assessing some types of sarcomas.
【答案】9．A 10．C 11．D
【导语】这是一篇说明文。文章介绍了研究表明在判断某些癌症的侵袭性方面人工智能的准确度几乎是活检的两倍，可以对肉瘤的风险进行分级。文章详细介绍了其研究过程，研究人员认为该算法未来可以应用于其他类型的癌症。
9．细节理解题。由第二段中“A recent study suggested an AI algorithm (算法) was far better than a biopsy at correctly grading the aggressiveness of sarcomas (肉瘤), a rare form of cancer. Researchers hope AI will improve outcomes for patients by giving doctors a more accurate way of grading tumours (肿瘤).

A
Jorg Muller, an ecologist at the University of Würzburg, with his colleagues, proposes a way to measure the biodiversity—listen to the jungle by AI, in a paper published in Nature Communications.
The rainforests are very important and always alive with the sounds of animals, which is useful to ecologists. When it comes to measuring the biodiversity of a piece of land, listening out for animal caller is more effective than uncovering the bushes looking for tracks and paw prints. The latter analysis method is time-consuming, and it requires an expert pair of ears. Muller’s idea was to apply the principle of smartphone apps which can identify the sounds of birds, bats and mammals to conservation work.
The researchers took recordings from across 43 sites in the rainforests. Some sites were relatively primitive, old-growth forests. Others were areas that had just been cleared for pasture(牧场) recently. And some other original forests had been cleared but then abandoned, allowing themselves to regrow. The various calls were identified by an expert,and then used to construct a list of the species present. As expected, the longer the land had been free from agricultural activity, the greater biodiversity it hosted. Then it was the computer’s turn. “We found that the AI tools could identify the sounds as well as the experts,” says Dr. Muller.
Of course, not everything in a rainforest makes a noise. Dr. Muller and his colleagues used light traps to catch night-flying insects, and DNA analysis to identify them. They found that the diversity of noisy animals was a reliable representative for the diversity of the quieter ones, too.
Besides measuring the biodiversity, the results are also expected to be applied to outside ecology departments. Under pressure from their customers, firms like L’Oreal, a make-up company, and Shell, an oil firm, have been spending money on forest restoration projects around the world. Dr. Muller hopes that an automated approach to checking on the results could help monitor such efforts, and give a standard way to measure whether they are working as well as their sponsors say.
1．Why does Muller propose to measure biodiversity with AI
A．To make a new conservation principle.
B．To seek away fit for hot environments.
C．To work more efficiently than manpower
D．To study the rainforests more specifically.
2．How was the identification work of AI tools on the 43 sites
A．It agreed with the work from experts..
B．It identified different types of raintarests.
C．It recorded more sounds in the abandoned forests.
D．It was used to restore the biodiversity for pasture.
3．What does the author indicate in paragraph 4
A．DNA analysis is skeptical in the research.
B．Quiet animals are as diverse as noisy ones.
C．A rainforest is always full of various noises.
D．AI technology is used to catch the insects.
4．What can be inferred from the last paragraph
A．The research focuses on biodiversity only.
B．L’Oreal and Shell develop monitoring apps.
C．The research will assist in forest restoration.
D．AI’s help will attract some sponsors’investment.

Artificial intelligence is almost twice as accurate as a biopsy (活组织检查) at judging the aggressiveness of some cancers, experts say. Cancer kills 10 million people globally every year, according to the WHO. But for patients the disease can be prevented if detected instantly and dealt with quickly.
A recent study suggested an AI algorithm (算法) was far better than a biopsy at correctly grading the aggressiveness of sarcomas (肉瘤), a rare form of cancer. Researchers hope AI will improve outcomes for patients by giving doctors a more accurate way of grading tumours (肿瘤). Because high-grade tumours can indicate aggressive disease, the tool could help ensure those high-risk patients are identified more quickly and treated instantly. Low-risk patients could also be spared unnecessary treatments, follow-up scans and hospital visits.
Researchers say the algorithm could be applied to other types of cancer in future. The team specifically looked at retroperitoneal sarcomas, which develop at the back of the abdomen and are difficult to diagnose (诊断) and treat due to their location. They used CT scans from 170 patients with the two most common forms of retroperitoneal sarcoma — leiomyosarcoma and liposarcoma. Using data from these scans they created an AI algorithm, which was then tested on 89 patients in other countries. In grading how aggressive the tumour was, the technology was accurate in 82% of the cases, while biopsies were 44%.
AI could also recognize leiomyosarcoma and liposarcoma in 84% of sarcomas tested, while radiologists were able to identify them in 65% of the cases. Christina Messiou, the study leader, said: “We’re incredibly excited by the potential of this state-of-the-art technology, which could lead to patients having better outcomes through faster diagnosis. As patients with retroperitoneal sarcoma are routinely scanned with CT, we hope this tool will eventually be used globally, ensuring that not just specialist centres can reliably identify and grade the disease.”
Richard Davison, chief executive of Sarcoma UK, said the results looked “very promising”. He added: “People are more likely to survive sarcoma if diagnosed early. One in six people with sarcoma cancer wait more than a year to receive an accurate diagnosis, so any research that helps patients receive better treatment and support is welcome.”
