21、AI that Sees like Humans
For most of the past 30 years computer-vision technologies have struggled to perform well, even in tasks as boring as accurately recognizing faces in photographs. 【1】. Companies are already selling products that exploit the technology, which is likely to take over or assist in a wide range of jobs that people now perform.
Recent progress in a deep- learning approach known as a convolutional neural network(CNN) is key to the latest progress. 【2】 While human can easily distinguish between a cat and a dog, CNNS allow machines to categorize specific breeds more successfully than people can.
CNNS do not need to be programmed to recognized specific features in images--- for example, the shape and size of an animal’s ears. 【3】 To train a CNN to separate an English springer spaniel (斯柏林格斯班尼犬) from a Welsh one, for instance , you start with thousands of images of animals, including examples of both breeds. Like most deep-learning networks, CNNS are organized in layers. In the lower layers, they learn simple shapes and edges from the images. In the higher layers, they learn complex and abstract concepts--- in this case, the more detailed aspects of ears, tails, tongues, fur textures, and so on.
CNNS were made possible by the tremendous progress in graphic processing units and parallel processing in the past decade. But the Internet has made a big difference as well by feeding CNNs’ appetite for digitized images. 【4】 The technology is making self-driving cars safer by enhancing the ability to recognize pedestrians. Insurers are starting to apply these tools to assess damage to cars. In the security camera industry, CNNS are making it possible to understanding crowd behavior, which will make public places and airport safer.
A. Once trained, a CNN can easily decide whether a new image of an animal shows a breed of interest.
B. Instead, they are taught to spot features such as these on their own.
C. Recently, though, breakthroughs in deep learning have finally enabled computers to interpret many kinds of images as successfully as , or better than , people do.
D. To give a simple example of its power, consider image of animals.
E. Computers-vision systems powered by deep learning are being developed for range of applications.
F. It excels because it is better able to learn, and draw inferences from telling patterns in the images
22、The UK will ban all new petrol and diesel-powered vehicles from its roads beginning in 19 years for environmental reasons, a government report says.
The plan aims to start removing petrol and diesel engines in 2040. It follows a similar official statement in France and comes after the British government was ordered by the High Court to develop new plans to reduce NO2 in the air. Judges ruled that previous clean-air plans were not enough to meet European Union pollution limits in the coming years.
The British government has said the poor air quality has an unnecessary and avoidable negative effect on citizens’ health, and costs up to $3.5 billion in annual lost productivity.
Part of the new plan involves an offer of $260 million to local governments to change rules where vehicle emissions (排放量) are over EU standards. Ideas so far include changing road layouts, reprogramming traffic lights and charging a fee for the oldest and most polluting cars on the road.
The plan also includes $1.3 billion for government purchase of extreme-low-emission vehicles, nearly $130 million to improve infrastructure for electric vehicle charging stations and $378 million for remodeling existing vehicles.
Climate change is also a reason for the plan to get these vehicles off the road. “We can’t carry on with petrol and diesel cars,” Environment Secretary Michael Gove said. “It’s important that we all prepare for a significant change which deals not just with the problems of health caused by emissions, but the broader problems caused in terms of accelerating climate change.”
Gove added that local communities are partly responsible for coming up with ways to limit emissions, including possible limitations on commuters (上下班往返的人) and the addition of cleaner mass transportation options. Local leaders are called on to draw up “appropriate plans” to deal with climate challenges related to emissions, he said.
【1】Why does the British government decide on this ban?
A.To focus on its citizens’ health.
B.To promote solar energy in transport.
C.To respond to the court’s request.
D.To follow in France’s footsteps.
【2】Which measure may the British government take to achieve its plan?
A.Limiting the number of traffic lights.
B.Changing the way roads are arranged.
C.Spending some money on electric vehicles.
D.Removing old and high-emission vehicles.
【3】What can be inferred from Gove’s words?
A.Convenient public transportation is badly needed.
B.Petrol and diesel cars may hold back economic progress.
C.Vehicle emissions are the key factor in climate change.
D.United efforts are required to achieve the plan.
【4】What is the suitable title for this passage?
A.Practical ways to reduce vehicle emissions.
B.The UK plans to take petrol and diesel engines off roads.
C.The EU forces the UK to improve the poor air quality.
D.Relationship between vehicle emissions and climate change.
23、A drug designed entirely by artificial intelligence is about to enter clinical human trials for the first time. The drug, which is intended to treat obsessive-compulsive disorder ( OCD)(强迫症),was discovered using Al systems from Oxford-based biotech company Exscientia. While it would usually take around four and a half years to get a drug to this stage of development, Exscientia says that by using the Al tools it's taken less than 12 months.
The drug, known as DSP・1181, was created by using algorithms (算法)to examine potential compounds (化合物),checking them against a huge database of parameters, including a patient's genetic factors. Speaking to the BBC, Exscientia chief executive Professor Andrew Hopkins described the trials as a “ key milestone in drug discovery “ and noted that there are “ billions” of decisions needed to find the right molecules (分子)for a drug, making their eventual creation a “ huge decision. “ With Al, however, “the beauty of the algorithms is that they are unknowable, so can be applied to any disease.”
We've already seen multiple examples of Al being used to diagnose illness and analyze patient data, so using it to engineer drug treatment is an obvious progression of its place in medicine. But the Al - created drugs do bring about some relevant questions. Will patients be comfortable taking medicine designed by a machine? How will these drugs differ from those developed by humans alone? Who will make the rules for the use of Al in drug research? Hopkins and his team hope that these and a great many other questions will be explored in the trials, which will begin in March.
【1】What is special about the drug designed by Al?
A.It's a better cure for OCD.
B.It has no side effect on humans.
C.Its development takes less time.
D.It doesn't need clinical human trials.
【2】Which is a key factor in creating the drug according to Paragraph 2?
A.Trials.
B.Algorithms.
C.Compounds.
D.Molecules.
【3】How does Hopkins feel about the way of drug creation?
A.Optimistic.
B.Doubtful.
C.Disappointed.
D.Puzzled.
【4】What can be the best title for the text?
A.Medical Trials by Al
B.An Example in Medical Trials
C.A Creation in Al Development
D.Al - designed Drugs to Be on Trial
24、Mr. Selfridge, the Wisconsin-born retailer (零售商) who left school at 14, rose to become a partner in Marshall Field's. Chicago. Founded in 1852, it was one of the first and most ambitious US department scores. Mr. Selfridge had done well with Marshall Field's. He liked to say, “The customer is always right,” which made the Chicago store popular. And he is believed to have invented the phrase “Only [so many] Shopping Days until Christmas”.
When he visited London on holiday in 1906 he was surprised to find most of the city's department stores were no match of their American and Parisian competitors. This led Selfridge to leave the US and establish Selfridges. a department store named after him. at the west end of London's Oxford Street. In Oxford Street, Selfridge's design team shaped an ambitious classical palacc building with a wall of plate glass windows.
Opened in 1909, Selfridges offered customers a hundred departments along with restaurants, a roof garden, reading and writing rooms, reception areas for foreign visitors, a first aid room and. most importantly, a small army of knowledgeable floor-walking assistants who served as guides as well as being thoroughly instructed in the art of making a sale.
Mr. Selfridge did much to make the department store a destination rather than just a big and comprehensively stocked city shop. It became a place to meet and for ladies to lunch. Mr. Selfridge later introduced the department store as a key element of the 20th Century culture, and Chaplin acknowledged the growing trend for shopping in the department store in his film The Floorwalker.
【1】What can be learned about Mr. Selfridge from Paragraph I ?
A. lie was well-educated.
B. He was a gifted businessman.
C. He was a modest man.
D. He was dishonest.
【2】What made Selfridge build a department store in London?
A. The large population in London.
B. His desire to own a department store.
C. His confidence in business success.
D. Affection for London architecture.
【3】What was Selfridges' most impressive characteristic?
A. The number of departments.
B. The broad choice of goods.
C. The small group of guards.
D. The well-trained sales guides.
【4】What is the main purpose of the article?
A. To introduce the history of Selfridge .
B. To compare different department stores.
C. To encourage readers to spend more.
D. To explain how to start a department store.
