【文章內(nèi)容簡(jiǎn)介】 ime. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to municate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there39。s something wrong. Besides, VR games will bee more popular with 5G. The short delay of 5G will make the games feel even more real. Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel far. On 4 networks, you can be 10 kilometers away from the nearest transmission (傳輸) base and barely lose signal. But 5G will only cover about 300 meters, meaning we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new specially, designed for 5G that are currently expensive.（1）What is the function of the first paragraph? provide a background of the topic. offer basic knowledge of the topic. use an example to support the topic. draw readers39。 attention to the topic.（2）According to the passage, what is likely to happen to our life with 5G? can treat more patients. drivers are needed in the near future. advanced technologies will be further improved. will hate playing VR games in the real world.（3）What can he found when 5G is pared with 4G? cover smaller areas. needs more transmitters. signals can travel farther. costs higher in early stage.（4）What is the text mainly about? development of 5G. that 5G will face. that people will get from 5G. difference that 5G will make to our lives.【答案】 （1）D（2）C（3）D（4）D 【解析】【分析】本文為一篇說(shuō)明文，介紹了5G時(shí)代的到來(lái)即將給人們的生活帶來(lái)的影響。 （1）考查推理判斷。根據(jù)第一段中的“Have you ever experienced such an annoying thing as it took so long to open a web page? You39。re watching stops every few minutes.”可知，第一段使用打開(kāi)網(wǎng)頁(yè)時(shí)間長(zhǎng)且卡頓的例子來(lái)吸引讀者并引出主題。故選D。 （2）考查推理判斷。根據(jù)第四段“With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to municate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there39。s something wrong. Besides, VR games will bee more popular with 5G. The short delay of 5G will make the games feel even more real.”可知，5G使無(wú)人汽車更安全；醫(yī)生更精準(zhǔn)獲取病人的病情；VR游戲玩起來(lái)更逼真。所有這些都得益于5G傳輸速度的極大提高。由此可推知，5G使許多先進(jìn)技術(shù)得到進(jìn)一步優(yōu)化。故選C。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的“ And in order to use 5G, we will have to buy new product specially designed for 5G that are currently expensive.”可知，為了使用5G，目前需要購(gòu)買價(jià)格昂貴的與之配套的新產(chǎn)品。由此可知，早期使用5G的成本要高于4G。故選D。 （4）考查主旨大意?？v觀全文可知，文章從一個(gè)現(xiàn)象引出對(duì)于5G的討論，介紹了5G的優(yōu)勢(shì)和早期存在的缺陷，講述了5G將給人們生活帶來(lái)的影響。故選D。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。5．閱讀理解 Google39。s new camera, called Clips, is a smart device. It es with a case that has a clip (夾子), but it39。s not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands and captures moments entirely on its own! What sets this roughly 2inch by 2inch camera, with a threehour battery life and Gorilla Glass for toughness apart is that it is specially intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone. The Clips device, it uses machine learning algorithms (計(jì)算程序) to help capture scenes. Those algorithms include face recognition. Once it learns that there39。s a face you see frequently, it39。ll try to get nice photos of those faces, said Juston Payne, the device39。s product manager. And they also want it to recognize facial expressions, which involved training it to know what happiness looks like. The Google team also trained it to recognize what not to shoot—like when a child39。s hand is over the lens, or if it is tossed in a dark purse. The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing. Concerned it could seem strange? Yes, Payne admitted, but he said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet. This product is only possible because of the way that silicon(硅) has advanced, Payne said that now they could squeeze the technology down into a device this size. Going forward, we39。re likely to get more assistance from the artificial intelligence packed into our apps and gadgets.（1）What is the most outstanding feature of Clips? enables easy Internet access. is equipped with tough glass. can be worn on your clothing. allows of handsfree photography.（2）What does the underlined word candid in Paragraph 2 mean? ....（3）What makes Clips a reality according to Juston Payne? advance in technology. popularity of the Internet. screen for viewing and editing. rise of the smartphone industry.（4）What does the text mainly talk about? gadgets in the age of apps. intelligence in daily Life. new digital camera from Google. alternative way to photograph.【答案】 （1）D（2）B（3）A（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了谷歌公司推出了一款叫Clips的新相機(jī)，并對(duì)照相機(jī)的各種功能和使用進(jìn)行了介紹。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own”可知，谷歌開(kāi)發(fā)的這款相機(jī)使用人工智能來(lái)拍照，不需要你動(dòng)手按鍵，它就可以幫助你記錄美好的精彩瞬間。故選D。 （2）考查詞義猜測(cè)。根據(jù)第二段中的“l(fā)ike when a child does something cute that may happen too quickly for you to pull out your smartphone.”比如孩子做了一些可愛(ài)的事情，你可能來(lái)不及拿出智能手機(jī)?？芍?，畫(huà)線句表示：這款相機(jī)能解決手機(jī)不能及時(shí)抓拍小孩子所做的短暫又可愛(ài)的事。candid moments意為“短暫”的時(shí)刻。故選B。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段“‘This product is only possible because of the way that silicon has advanced, ’ Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we39。re likely to get more assistance from the artificial intelligence packed into our apps and gadgets”可知，這款相機(jī)依靠先進(jìn)的科技和人工智能等使得它成為了可能，成為了可以幫助人們記錄美好瞬間的工具。故選A。 （4）考查主旨大意。根據(jù)第一段中的“Google39。s new camera, called Clips, is a small, smart device.”可知，本文主要講述了谷歌開(kāi)發(fā)的一款新的照相機(jī)，并對(duì)照相機(jī)的各種功能和使用進(jìn)行了介紹。故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和主旨大意三個(gè)題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。6．閱讀理解 Durian(榴蓮) is probably the smelliest fruit in the world, letting out an unusual unpleasant smell which would make anyone bring up. However, nobody was aware of what gave this fruit its unique smell, so a team of researchers from Singapore decided to take a look at its genome (基因組) and find out,16
