6、ickness to pick a strawberry or a salad.While crops like wheat and potatoes have been harvested mechanically for decades, many fruits and vegetables have proved resistant to automation.They are too easily damaged, or too hard for heavy farming machines to locate.But recently, technological developme
7、nts and advances in machine learning have led to successful trials of more sensitive and skillful robots, which use cameras and artificial intelligence to locate ripe fruits and handle them with care and precision.Developed by engineers at the University of Cambridge, the Vegebot is the first robot
8、that can identify and harvest iceberg lettuce(a vegetable with pale green leaves that form a tight ball)一bringing hope to farmers that one of the most demanding crops for human pickers could finally be automated.First, a camera scans the lettuce and, with the help of a machine learning algorithm(算 法
9、)trained on more than a thousand lettuce images, decides if it is ready for harvest.Then a second camera guides the picking cage on top of the plant without crushing it.Sensors feel when it is in the right position, and pressed air will drive a blade through the stalk (茎)at a high force to get a cle
10、an cut.Its success rate is high, with 91%of the crop accurately classified,according to a study published in July.But the robot is still much slower than humans, taking 31 seconds on average to pick one lettuce.Researchers say this could easily be sped up by using lighter materials.Such adjustments
11、have to be made if the robot is used commercially. Our goal was to prove we can do it, and wee done it now, “ Simon Birrelh co-author of the study, said ,“ Now it depends on somebody taking he baton (接 力棒)and running forwaid.”K语篇解读X本文是一篇科普说明文,介绍了一款蔬菜采摘机器人。28 .Whafs the purpose of mentioning picking
12、strawberries in Paragraph 1? A.To fuel readers interest.B.To show the high speed of picking fruits.C.To indicate crops can be easily damaged.D.To imply machines cant handle soft fruits.答 案 H D K 推理判断题。由第一段中many fruits and vegetables have proved resistant to automation”一句可知,许多水果和蔬菜难以被机器人采摘。所以此处 提到摘草莓
13、是为了说明机器人无法采摘草莓这类的水果。.What does the underlined sentence mean in the last paragraph?A.It is impossible to enable the robot to run forward.29 Human pickers will be replaced by the Vegebot soon.C.A pioneer is needed to promote the development of the robot.D.The Vegebot will be marketed around the globe
14、soon.K答 案I c K句意推断题。画线局部的字面意思是:现在需要一个拿着接力 棒向前跑的人。由此可以推断,目前,由于这种采摘机器人在技术上还有很多缺 点,需要一个开拓者继续推动研发工作。因此选C。130.From the passage we know the Vegebot.A.uses a machine learning algorithm to harvestB.is developed by human pickersC.performs faster than human pickersD.can be accelerated by using artificial mate
15、rialsK答 案H A K细节理解题。根据第三段中的“ the Vegebot is the first robot that can identify and harvest iceberg lettuce”和第四段首句可知,采摘机器人是利用机 器学习算法来工作的。应选A。r31 .What is Paragraph 4 mainly about?A.The result of sensors cutting the stalk.B.The process of the Vegebofs harvesting the lettuce.C.The working of the cameras

17、ct solution.uFirst of all, its still not bright enough-you have to remember how respectable sunlight is, “ said Shin-Tson Wu, a physicist at the University of Central Florida.The other problem, he says of the brightened screen, is that it kills the battery.So Wu and his colleagues have produced a ba
18、ttery-sparing alternative: an anti-reflective screen coating, based on the eyes of moths.Nature is so rich! We can learn a lot from nature/The thing Wu and others have learned about moths eyes, is that theyre uneven, dotted with tiny projections.That uneven surface reduces the reflection of light of
19、f their eyes, thought to help the bugs escape predators (捕食动物),and see better in low light.So Wu and his team built a similar surface with tiny dimples(小凹),to cut down on glare.He says the coating could improve the readability of a screen by five to ten times, compared to a normal smart phone screen
20、.The details are in the journal Optica. The technology hasnt been commercialized yet, and that could take a few years, which gives researchers time to take advantage of another property of these surfaces-theyre flexible, meaning the possibility of bendable displays.Combining that with the bendy batt
21、eries we reported on in a recent podcast (播客),the smart phones of the future could be set for a real transformation.K语篇解读R 研究人员从飞蛾的眼睛构造中得到启示,研制了抗反射手机屏涂 层。这种涂层可以改善屏幕的清晰可辨性,从而减少增亮屏幕时手机电池的使用。 32.Why do the researchers develop the anti-reflective screen coating?A.To brighten the screen.B.To make profits
22、.C.To use smart phones in the sunlight.D.To save the use of battery.K答 案H D K细节理解题。根据第二段中的The other problem, he says of.an anti-reflective screen coating”可知,研究人员研制抗反射手机屏涂层是为了减少 手机电池的使用。力.What inspired the invention of the screen coating?A.The predators.B.The reflection of light.C.The eyes of moths.D
23、.The smooth surface.K答 案H C K细节理解题。根据第二段中的“an anti-reflective screen coating, based on the eyes of moths ”并结合该段其他内容可知,飞蛾的眼睛启发研究人员 研制了防反射屏幕涂层。H.How does the screen coating work?A.It helps bugs escape.B.It slows down reading.C.The smooth surface protects our eyes.D.The rough surface decreases the refl
24、ection of light.(答 案H D K细节理解题。根据第二段倒数第四句中的“Thatuneven surface reduces the reflection of light off their eyes” 以及倒数第三句中的“So Wu and his team built a similar surface”可知,这种屏幕涂层通过其不平的外表来减少光的反射。U 35.What do the researchers expect of the screen?A.ItUl transform itself.B.Itll be environmentally friendly.C.
