Myopia, or nearsightedness, is a common eye condition in which you can see objects near to you clearly, but objects farther away are blurry.To see the farther things clearly, you have the option of wearing eyeglasses, or undergoing the more invasive refractive surgery.
But Japan's Kubota Pharmaceutical Holdings Co.Ltd.claims to have developed smart glasses that, if worn just an hour per day, can cure myopia.It projects an image onto the wearers' retina (视网膜) to correct the refractive error that causes nearsightedness.Obviously, wearing the device 60 to 90 minutes a day corrects myopia.
So how does the technology developed by the company work exactly Well, according to a company press release in December of last year, the special glasses rely on micro-LEDs to project virtual images on the visual field to make the retina active.Apparently, it can do that without affecting the wearer's daily activities.
Founded by Dr Ryo Kubota, Kubota Pharmaceutical Holdings Co.Ltd.is still testing the device, known as Kubota Glass ， and trying to determine how long the effect lasts after the user wears the device, and how long the ugly-looking glasses have to be worn for the correction to be permanent.
Kubota Pharmaceutical Holdings Co.Ltd.began testing the glasses in the summer of last year, and is currently conducting tests on about 25 people in the US to assess the effectiveness of its smart glasses.The company plans to begin selling the device in Asia in the second half of next year where there are more nearsighted people, but it has planned to enter other markets in the future.

1．What does the underlined word “blurry” mean in the first paragraph
A．Familiar. B．Different.
C．Impressive. D．Unclear.
解析：选D 词义猜测题。根据第一段中的“Myopia, or nearsightedness ...farther away are blurry.”可知，近视是能看清近距离的物体看不清远距离的物体，故画线词意为“模糊不清的”。
2．What does the third paragraph mainly talk about
A．The effect of wearing the smart glasses.
B．The disadvantages of the smart glasses.
C．The working principle of the smart glasses.
D．The correct way of wearing the smart glasses.

3．Why does the company decide to sell the glasses first in Asia
A．It wants to serve the Asians better.
B．These glasses are more suitable for Asians.
C．Scientific development is slower in Asia.
D．There is more market demand in Asia.
解析：选D 推理判断题。根据最后一段中的“where there are more nearsighted people”可知，亚洲近视的人较多，即市场需求大。
4．What is the purpose of writing the text
A．To solve a problem.
B．To introduce a new product.
C．To present a research result.
D．To give practical advice.
解析：选B 写作意图题。本文主要介绍了日本一家公司研发的一种可以矫正近视的智能眼镜，故其写作目的是介绍一种新产品。
B
(2023·哈尔滨模拟)Many people count on faster, cheaper and better technology to offer a vision of a brighter future. Nevertheless, as the 2020s dawn, optimism is in short supply. The new technologies that dominated the past decade seem to be making matters worse. Social media were supposed to bring people together, but they are better known for leaking privacy. E-commerce, ride-hailing and the gig economy (零工经济) may be convenient, but they are charged with underpaying workers, worsening inequality and blocking the streets with vehicles.
Today's pessimistic mood is centered on smart phones and social media, which took off a decade ago. Yet concerns that particular technologies might be doing more harm than good have arisen before. The 1920s witnessed a criticism against cars, which had earlier been seen as an answer to the problems caused by horse-drawn vehicles which filled the streets with noise and animal waste and caused accidents. And industrialization was criticized in the 19th century by Romantics who worried about the replacement of skilled workers, the robbing of the countryside and the suffering of factory hands.
However, that pessimism can be overdone. Too often people focus on the drawbacks of a new technology while taking its benefits for granted. Worries about screen time should be weighed against the much more substantial benefits of convenient communication and the instant access to information and entertainment that smartphones make possible. A further danger is that Luddite (反对技术进步者) efforts to avoid the short-term costs associated with a new technology will end up denying access to its long-term benefits — something Carl Benedikt Frey, an Oxford academic, calls a “technology trap”. Fears that robots will steal people's jobs may discourage their use. Yet in the long run countries that wish to maintain their standard of living as their workforce ages and shrinks will need more robots, not fewer.
Any powerful technology can be used for good or ill. It is the choices people make about it that shape the world. Perhaps the real source of anxiety is not technology itself, but growing doubts about the ability of societies to hold this debate, and come up with good answers. So as the decade turns, put aside the pessimism for a moment. To be alive in the tech-obsessed 2020s is to be among the luckiest people who have ever lived.
语篇解读：本文是一篇议论文，主要论述了科技所带来的悲观情绪。
5．According to the passage, which of the following is a problem caused by new technologies
A．Endless hacking.
B．Network viruses.
C．Convenient communication.
D．Leaking privacy.
解析：选D 细节理解题。根据第一段的“Social media ... are better known for leaking privacy.”可知，新技术引起的问题是泄露隐私。
6．Which word can best describe Romantics' concern over industrialization
A．Negative. B．Uncertain.
C．Sympathetic. D．Enthusiastic.
解析：选A 推理判断题。根据第二段的“And industrialization was criticized in the 19th century by Romantics ...”可知，浪漫主义者对工业化的担忧是消极否定的。
7．What might be a result of a “technology trap”？
A．A lack of good jobs in the job market.
B．An increase in the number of Luddites.
C．A decrease in the number of skilled workers.
D．An interruption to the advancement of a new technology.
解析：选D 推理判断题。根据第三段的“Fears that robots will steal people's jobs may discourage their use.”可推断出，人们不愿用新技术，因此“技术陷阱”的一个结果可能是一项新技术进步的中断。
8．What can we know from the passage
A．Man is blessed to live in the 2020s with high tech advancing fast despite some drawbacks.
B．All the people object to the progress technology brings because it harms our civilization.
C．The 2020s is the Age of Technology and mankind is suffering a lot due to its influence.
D．Humans completely depend on our future caretakers — robots.
解析：选A 细节理解题。根据最后一段最后两句可知，尽管科技会带来一些弊端，但人类有幸生活在高科技快速发展的21世纪20年代。

Ⅰ.阅读理解
Melanie Clapham has spent the last three years catching images of grizzlies (灰熊) at Knight Inlet, on the B．C.coast, using small camera traps housed in metal and attached securely to the forest branches.
Three years and thousands of images later, the behavioral researcher and postdoctoral student at the University of Victoria has partnered with two software developers living in Silicon Valley and a grizzly research centre in Alaska to develop facial recognition technology used to identify the bears.
“They don't have distinctive markings on their bodies，” said Clapham, whose interest in this technology sprang from the need to “identify and recognize individual bears over time” as part of her behavioral research over the last 11 years.
Bears grow and shrink a lot depending on the season, and their appearance changes frequently during their 20- to 25-year-long lifespans.Clapham began to wonder if AI might be able to solve her problem in the same way the technology recognizes people's faces.
Now, she says, the open-source BearID software can be used and adapted by anyone and could have huge hints for understanding the animals' behaviour and avoiding bear-human encounters.
In relation to the technology based on human facial recognition, Ed Miller and his partner Mary Nyugen are the software developers from California who connected with Clapham in an online forum for conservation technology in late 2017.
The pair were looking for photos of bears “for fun” as a way to learn more about recognition software, and so they connected with Clapham to offer their expertise (专业知识) in adapting artificial intelligence.
“The technology we're using is based on the same software used to recognize humans，” said Miller, who added that human identification is far easier, as there are millions of images the software can learn from.
“We need lots of images of individual animals to tell the system which bear is which，” said Clapham, who explained “deep learning” as the process where the software trains itself to recognize certain bears more accurately with more pictures it gets.Clapham says BearID currently has an 84-percent accuracy rate.This is especially important, given that a bear will look dramatically different throughout the year as its appearance, especially fur and weight, changes a lot.
语篇解读：本文是一篇说明文，介绍了一款运用面部识别技术研发的识别灰熊的软件。
