Just after hatching, many birds learn to identify and follow the first moving object they encounter—a process called imprinting, which can offer protection in the wild as it helps them stay near a parent. It doesn’t take much visual information for a bird to learn to prefer one object and follow it. Researchers wanted to know whether AI models called transformers could do a similar task with limited inputs.

Transformers are generic learning systems that can be trained to perform a wide variety of tasks, making them useful in both AI chatbots such as ChatGPT and in computer vision applications, such as autonomous car navigation.

“To directly compare learning algorithms (计算程序) to brains, we need to train them on the same experiences,” says Samantha Wood at Indiana University Bloomington. She first raised chicks in a box where the only visual stimulation came from a rotating 3D object presented on a screen. After the first week, she ran each chick through hundreds of test trials that showed that same object on one screen-presented from both familiar and unfamiliar perspectives-and displayed a second unfamiliar object on another screen. The chicks spent more of their time near the first object, suggesting they had imprinted on it.

The researcher then created a virtual simulation (仿造物) of the set-up and used a virtual agent to move through it while looking around and recording a first-person view. That provided tens of thousands of simulated images for training and evaluating four transformer models.

The AI models had just 300 milliseconds to learn from each simulated image-approximating (接近于) how long biological neurons (神经元) fire after being presented with an image. The researcher found that the AIs could learn to recognise a 3D object as quickly and accurately as the chicks.

The study is “a great piece of work” in comparing machine performance with biological brains, says Antone Martinho-Truswell at the University of Sydney. But he also notes, “We might be able to say that the chick ‘saw’its imprinting object, but that will have a component (成分) of experience to it. Particularly as imprinting is to do with identifying its mother, it would be unsurprising if that visual experience were combined with a suite of other components of experience: fear yielding to comfort, for example, as the chick comes to regard the object as its imprinted ‘mother’.”

1. Why do newborn birds engage in imprinting?
A.To enhance their navigation skills.
B.To develop their social behaviour.
C.To improve their communication with other birds.
D.To establish a protective connection with a guardian.
2. How did Samantha Wood conduct the initial experiment with chicks?
A.She raised them in an environment with a rotating visual element.
B.She exposed them to various visual stimulations in the wild.
C.She showed them various moving objects on screens.
D.She observed their behaviour in a natural habitat.
3. What role did the virtual simulation play in the research?
A.To imitate the natural behaviour of birds.
B.To assess the effectiveness of virtual agents.
C.To examine the Al models’ability to identify a 3D object.
D.To create a visually diverse environment for the chicks.
4. According to Antone Martinho-Truswell, what poses a challenge in comparing machine performance with biological brains?
A.Rapid learning pace of AI models.
B.Recreating real-world environments for experiments.
C.The complexity and diversity of biological experiences.
D.Conducting additional experiments with a range of animals.

文章大意:本文是一篇说明文。作者主要讲述了几位研究者所研究的一种未来农业模式:不需要阳光和雨水的室内农业,它不同于温室农业,足一种节能、节水和环保的农业模式,具有适应性强、成本低等特点。

【推荐1】Farming is moving indoors, where the sun never shines, where rainfall is irrelevant(不相干的)and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature, wetness, air quality and nutrition. It could be a high-rise building in New York or a sprawling complex(综合楼) in the Saudi desert. It may be an answer to the world’s food problems.

The world is already having trouble feeding itself. Half of the people on earth live in cities, and nearly half of those—about 3 billion—are hungry or ill-fed. Food prices, currently increasing, are buffeted by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world are already using water available to the last drop. And the world is getting more crowded: by mid-century, the global hungry population will grow to 9 billion.

To feed so many people may need to expand farmland at the expense of forests and wilderness, or finding ways to completely increase crop output.

Gertjan Meeuws has taken the concept of greenhouse—growing vegetables and house plants in enclosed(封闭的)and controlled environments. In their research station, water flows into the pans when needed, and temperature is kept constant. Lights go on and off, creating similar day and night according to the rhythm of the plants.

A building of 100 square meters and 14 layers(层)of plants could provide a daily diet of 200 kilograms of fresh fruit and vegetables for the entire population of Den Bosch, about 140,000 people. Their idea is not to grow foods that require much space, like corn or potatoes.

Here sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than those under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near consumers, so there’s no need to transport it long distances.

1. What does Paragraph 2 mainly tell us?
A.The climate is worse and worse.B.The city people live a hard life.
C.The world has difficulty feeding its people.D.The world’s population is increasing fast.
2. The underlined word “buffeted” in Paragraph 2 means “________”.
A.badly affectedB.preventedC.demandedD.well achieved
3. It can be inferred from the text that Gertian Meeuws’s farming ________.
A.helps save sea water a lot
B.suits different conditions
C.is completely different from greenhouse agriculture
D.suits the production of corn
4. What is the text mainly about?
A.The development of indoor farming.B.A great revolution in farming.
C.Advantages of indoor farming.D.Sunless and rainless indoor farming.

文章大意:本文是一篇议论文。主要论述了教育的目的是培养良好的知识鉴赏力和良好的行为方式以及懂得什么该爱,什么该恨,对知识有鉴赏力的人才是博学的人。
【推荐2】阅读下面短文,根据题目要求用英文回答问题。

Good Taste of Knowledge

The aim of education or culture is merely the development of good taste in knowledge and good form in conduct. The cultured man or the ideal educated man is not necessarily one who is well-read or learned, but one who likes and dislikes the right things. To know what to love and what to hate is to have taste in knowledge.

Nothing is more annoying than to meet a person at a party whose mind is crammed (填塞) full with historical dates and figures and who is extremely well-posted on current international affairs, but whose attitudes or points of view are all wrong. I have met such people. They do have great academic knowledge, but no good judgment or taste. Being knowledgeable is a mere matter of the cramming of facts or information while having good taste is a matter of artistic judgment. In speaking of a scholar, the Chinese generally distinguish between their scholarship (学术成就), conduct and taste..

An educated man, therefore, is one who has the right loves and hatreds. This we call taste, and with taste comes charm. Now, to have taste requires a capacity for thinking things through to the bottom, the independence of judgment, and the unwillingness to be affected by any form of power.

When a man is wrong, he is wrong, and there is no need for one to be impressed by a great name or by the number of books that he has read and we haven't.

Taste, then. is closely associated with courage. as the Chinese always associated dan (“胆”) with shi (“识”) And courage or independence of judgment, as we know, is such a rare virtue among humankind. We see this intellectual courage or independence during the childhood of all thinkers and writers who in later life amount to anything. Such a person refuses to be impressed by a philosophic vogue or a fashionable theory, even though it is backed by the greatest name. this is taste in knowledge.

No doubt such intellectual courage or independence of judgment requires a certain childish. nave confidence in oneself, but this self is the only thing that one can cling to. and the moment a student gives up-his right of personal judgment, he is m for accepting all the dishonest and insincere of life.

1. According to the author, what is the goal of education?
____________________________________________________________________________________________
2. Why is a well-read man not necessarily an educated one?
____________________________________________________________________________________________
3. Please decide which part is false in the following statement: Intellectual courage or independence of judgment builds confidence in oneself; then underline it and explain why Intellectual courage or independence of judgment builds confidence in oneself.
____________________________________________________________________________________________
4. Please name one person with the qualities of dan and shi in Chinese history and explain what about this person makes you think so. (In about 40 words)

文章大意:本文是一篇说明文,介绍了一项关于半睡半醒与创造性的关系的试验。

【推荐3】The twilight (朦胧的) time between full wakefulness and being sound asleep may be packed with creative potential. Rumor has it that Thomas Edison, the famous inventor, used to prefer such moments between wakefulness and sleep. Supposedly, he used to fall asleep in a chair holding two steel balls. As he fell asleep, the balls fell into metal pans. The resulting sound woke him. Then, he could write down his inventive ideas before he fell into a deep sleep and forgot them.

Researchers tested Edison’s method of developing creativity with 103 healthy people. Volunteers came to the lab to solve a tricky number problem. After doing the task 60 times, they earned a 20-minute break in a quiet, dark room. They relaxed in chairs, each holding a light drinking bottle, something like the steel balls that Edison used. Participants were told to close their eyes and rest or sleep if they desired. Meanwhile, machines monitored their brain waves. About half of the participants stayed awake. Twenty-four fell asleep and stayed in the shallow short stage of sleep called N1. Fourteen others progressed to N2, a deeper stage of sleep.

After their rest, participants returned to their number problem. The researchers saw a clear difference between the groups. People with a shallow early sleep were 2.7 times as likely to spot the hidden trick as people who stayed awake. Shallow sleepers were 5.8 times as likely to spot the trick as people who reached the deeper N2 stage.

Such differences in such experiments are rare, says Delphine Oudiette, a cognitive neuroscientist. “The results raise an interesting possibility. It may help people to learn to reach that twilight stage of sleep on demand. It seems Edison was onto something about the creative powers of nodding off. But don’t put too much faith in his habits. He also is said to have considered sleep ‘a criminal waste of time’.”

1. Why is Thomas Edison mentioned in paragraph 1?
A.To imply the inspiration of the study.B.To explain how habits can help.
C.To support the idea theoretically.D.To lay scientific basis of the study.
2. What can be known about the drinking bottle?
A.It belonged to Thomas Edison.B.It was made of a kind of steel.
C.It may serve as an alarm o'clock.D.It was in the shape of a metal pan.
3. What did the study find?
A.Being awake is as creative as being asleep.
B.Wakefulness differs from sleep in many aspects.
C.Being asleep is more productive than wakefulness.
D.Shallow sleepers may be better problem solvers later.
4. How does Oudiette like the study?
A.Ridiculous.B.Doubtful.C.Realistic.D.Useful.
