In some countries it's even the law. But a company from South Korea has developed an app that can identify dogs a little less invasively. On this phone, I've got the new app, PetNow, which is now using the dog's nose print to identify a dog, just like you can use a fingerprint of a human to make identification. A dog's nose print is very similar as well. 1 2 3 4 5 6 7 8 课 后 习 题 33 “Now show me your nose, buddy.” It takes me a few seconds to take pictures of the dog's nose. “Oh yes, I made it, okay! Then who is the dog? Is it Emma, Lenard, Karl, or Ethan?” The app analyses the data in the cloud and tells me that this is Emma, and not only that, it's showing me that Emma's been reported as missing. And it's telling me where she was reported missing, and I can share my location with the owner, so they can be reunited. 1 2 3 4 5 6 7 8 课 后 习 题 Unlike a microchip, which could be cut out of a stolen dog, you can't really remove a dog's nose, not without spoiling the dog. And by using the phone's camera to scan, anyone in theory can check a stray dog without any specialist equipment. Recently, I've spoken to PetNow to find out why they'd settled on nose prints for dog recognition. There may be paws or ears, but some dogs really hate showing up, sharing their paws or their ears. Their nose is actually exposed all the time. And after a dog becomes six months old, the nose print stays 1 2 3 4 5 6 7 8 课 后 习 题 there for its entire life, so they believe that it is the best part for identification. PetNow hopes its app will become mandatory in South Korea to help reduce the number of dogs that are abandoned by pet owners. To do that they will need the backing of the government and a huge marketing push, so that everybody including people who don't own a dog must install the app and know how to use it. 【文章大意】本文是一篇说明文。文章主要介绍了应用程序PetNow， 它可以通过狗的鼻纹对狗进行识别。 1 2 3 4 5 6 7 8 课 后 习 题 ( )1.Which can be inferred from the passage? A.Dogs' prints are very similar. B.Microchipping a dog is out of date. C.The app can map out a lost dog's original place. D.The app requires specialist equipment. [解析] 推理判断题。根据第三段“And it's telling me where she was reported missing, and I can share my location with the owner, so they can be reunited.”可推知，应用程序PetNow可以标 记出已丢失小狗的原始位置。故选C。 √ 1 2 3 4 5 6 7 8 课 后 习 题 37 ( )2.Why did PetNow settle on nose prints for dog recognition? A.Because a microchip can be cut out. B.Because some dogs hate showing up. C.Because their nose print never changes. D.Because their nose is easy to photograph. [解析] 细节理解题。根据倒数第二段“There may be paws or ears, but some dogs really hate showing up, sharing their paws or their ears. Their nose is actually exposed all the time.”可知， PetNow选定鼻纹进行识别，是因为狗的鼻子一直暴露在外，更容易 被拍摄。故选D。 √ 1 2 3 4 5 6 7 8 课 后 习 题 38 ( )3.Which of the words best explains the underlined word “mandatory” in the last paragraph? A.Safe. B.Required. C.Professional. D.Easy. √ 1 2 3 4 5 6 7 8 课 后 习 题 39 [解析] 词义猜测题。根据最后一段“PetNow hopes its app will become mandatory in South Korea to help reduce the number of dogs that are abandoned by pet owners. To do that they will need the backing of the government and a huge marketing push, so that everybody including people who don't own a dog must install the app and know how to use it.”可知，要达到这个 目的，需要政府的支持和巨大的市场推广，每个人都必须安装这款 应用程序，由此可推测画线词表示“强制性的”，与required同义。故 选B。 1 2 3 4 5 6 7 8 课 后 习 题 40 ( )4.What's the best title of the passage? A.Taking pictures for a dog's nose B.Nose print technology on the way C.PetNow saves abandoned dogs D.PetNow identifies dogs with their nose print √ 1 2 3 4 5 6 7 8 课 后 习 题 41 [解析] 主旨大意题。根据第一段“On this phone, I've got the new app, PetNow, which is now using the dog's nose print to identify a dog, just like you can use a fingerprint of a human to make identification.”以及文章内容可知，本文主要介绍了应用程 序PetNow，它可以通过狗的鼻纹对狗进行识别，所以“PetNow用鼻 纹识别狗”可以作为文章标题。故选D。 1 2 3 4 5 6 7 8 课 后 习 题 42 B There is a new kind of robot called Rubion which can smartly tell ripe (成熟的) strawberries, picking them without bruising them and putting them into its basket. It sounds impossible but it is true. Its appearance is not only an answer to the labour shortage in the agricultural industry, but it also allows growers to increase the quality of produce, which in the end benefits the consumers. 1 2 3 4 5 6 7 8 课 后 习 题 43 It has been a fact that there is a labour shortage in the agricultural industry. But for Octinion Technology Group, the focus is clearly on adding quality. “Thanks to robotics, we have so many possibilities, much more than a human could ever do. Harvest prediction, picking according to market needs, simply picking when the berries are ripe instead of when workers are available—these are just a few examples of what is possible now for a grower,” says Tom Coen, CEO of the Octinion Technology Group. “The consumer will also notice the difference, as strawberries will be fresher and show less bruising.” 1 2 3 4 5 6 7 8 课 后 习 题 Introducing robots into an industry where almost everything gets done by hand is more of a revolution (变革) than evolution. It needs close group action with all partners. Tom Coen says, “Not only have we been working together with growers and test centres across the world for the past few years, but breeders (培育者) have been active in being part of the technological development.” In 2022, a team of Belgian engineers started the development of the robot. In the meanwhile Octinion wasn't the 1 2 3 4 5 6 7 8 课 后 习 题 only company presenting an idea. Product Manager Laura Guillaume says it's not a surprise that the company from Leuven is the first to actually present a commercial product. “By developing the robot from the beginning, we are able to make it practical in greenhouses or tunnels.” Octinion plans to develop harvesting robots for other crops in the future. 【文章大意】本文是一篇说明文。文章介绍了一种名为Rubion的新 型机器人,它能够识别成熟的草莓,而且能够在采摘时不损伤草莓。 1 2 3 4 5 6 7 8 课 后 习 题 ( )5.What does the underlined word “bruising” in Paragraph 1 refer to? A.Taking advantage of. B.Losing track of. C.Having a bad effect on. D.Making no harm to. [解析] 词义猜测题。根据上文“…which can smartly tell ripe (成熟的) strawberries…”和后文“…but it also allows growers to increase the quality of produce…”可知,机器人能识别成熟的草莓且 能帮助种植者提高农产品的质量。因此猜测它能完好地将草莓摘下 来,由此推知bruising应是“损伤”之意,和C项意思相近。故选C。 √ 1 2 3 4 5 6 7 8 课 后 习 题 47 ( )6.What can the robot help a grower do? A.Find a close partner. B.Pick a skilled worker. C.Make a market survey. D.Fix a right harvest time. √ 1 2 3 4 5 6 7 8 课 后 习 题 48 [解析] 推理判断题。根据第二段“‘Thanks to robotics, we have so many possibilities, much more than a human could ever do. Harvest prediction, picking according to market needs, simply picking when the berries are ripe instead of when workers are available—these are just a few examples of what is possible now for a grower,’ says Tom Coen, CEO of the Octinion Technology Group.”可知,机器人能根据市场需求采摘或者在浆果成 熟的时候采摘,即能确定一个合适的收获时间。故选D。 1 2 3 4 5 6 7 8 课 后 习 题 49 ( )7.What is the author's attitude to the robot's introduction? A.Favourable. B.Cautious. C.Unclear. D.Worried. [解析] 推理判断题。根据第三段“Introducing robots into an industry where almost everything gets done by hand is more of a revolution (变革) than evolution.”可知,作者认为将机器人引入农 业是一场变革,能够带来许多好处,所以是支持的。故选A。 √ 1 2 3 4 5 6 7 8 课 后 习 题 50 ( )8.What can be the best title for the text? A.Robots can solve labour shortage B.Robots can create many possibilities C.Harvesting methods are worth improving D.Modern agriculture needs new equipment √ 1 2 3 4 5 6 7 8 课 后 习 题 51 [解析] 主旨大意题。通读全文，尤其根据第一段“There is a new kind of robot called Rubion which can smartly tell ripe (成熟的) strawberries, picking them without bruising them and putting them into its basket. It sounds impossible but it is true. Its appearance is not only an answer to the labour shortage in the agricultural industry, but it also allows growers to increase the quality of produce, which in the end benefits the consumers.”可 知,本文主要讲述了人们将像Rubion这样的机器人引入农业领域,为种 植者带来了许多新的可能性,包括提高作物质量、增加效率、解决劳 动力短缺问题以及惠及消费者。所以B项(机器人可以创造许多可能 性)适合做本文标题。故选B。 1 2 3 4 5 6 7 8 课 后 习 题 52 Ⅴ语法填空(每小题1.5分，满分15分) The 2023 Nobel Prize in Physics has been awarded to a team of scientists who created a groundbreaking technique using lasers (激光) to understand the extremely rapid movements of electrons, which were 1.__________(previous) thought impossible to follow. “Pierre Agostini, Ferenc Krausz and Anne L'Huillier demonstrated a way to create extremely short pulses (脉冲) of light that can 2._________(use) to measure the rapid processes previously be used 1 2 3 4 5 6 7 8 9 10 课 后 习 题 53 in which electrons move or change energy,” the Nobel Committee said when the prize was announced in Stockholm on Tuesday.
