【正文】 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】本文為一篇說明文，介紹了5G時代的到來即將給人們的生活帶來的影響。 （1）考查推理判斷。根據第一段中的“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，第一段使用打開網頁時間長且卡頓的例子來吸引讀者并引出主題。故選D。 （2）考查推理判斷。根據第四段“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使無人汽車更安全；醫(yī)生更精準獲取病人的病情；VR游戲玩起來更逼真。所有這些都得益于5G傳輸速度的極大提高。由此可推知，5G使許多先進技術得到進一步優(yōu)化。故選C。 （3）考查細節(jié)理解。根據最后一段中的“ 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，目前需要購買價格昂貴的與之配套的新產品。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，文章從一個現象引出對于5G的討論，介紹了5G的優(yōu)勢和早期存在的缺陷，講述了5G將給人們生活帶來的影響。故選D。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科技類閱讀，考生需要準確掌握細節(jié)信息，同時根據上下文進行邏輯推理，概括歸納，從而選出正確答案。7．閱讀理解 New South Wales, Australia, is setting up cameras as part of an effort to reduce the number of people preoccupied with wireless devices while they drive. It will be the first area in the world to use the technology to punish drivers distracted (分心) with telephone calls, social media or text messages. Road Safety experts are concerned about the growing number of accidents involving drivers using smart phones on the state39。s roads. They say drivers who use phones while driving greatly increase their chances of being involved in an accident. The New South Wales government plans to place 45 Mobile Phone Detection Cameras across the state by December. Each phone detection unit contains two cameras. One camera takes pictures of a vehicle39。s registration plate (牌照). A second camera looks through the front window of a car or truck to see what drivers are doing with their hands. The units use artificial intelligence to set aside drivers who are not touching their phones. Human beings then confirm if the pictures show illegal behavior before notice is sent to the vehicle39。s registered owner. A violation (違反) carries fine of $232. Some cameras will be permanently set up on roadsides. Others will be moved, from time to time, around the state. Two fixed cameras took photographs of million vehicles as part of a sixmonth test earlier this year. The cameras took photos of more than 100,000 drivers with their hands on phones. One driver was using a phone and another electronic device, an Apple iPad, at the same time. Another driver had a passenger guide the vehicle while they both held phones, the state government said.（1）What is the real purpose to set up cameras in New South Wale? keep records of the accidents. promote the latest technology. find illegal behavior of the drivers. force drivers to focus more on driving.（2）What can we infer from the road safety experts? are main killers on the road. accidents result from drivers39。 using cellphones. are badly needed to ban using phones while driving. a smartphone while driving will cause an accident.（3）How does the phone detection unit function effectively? corrects the drivers39。 wrong behavior. has two cameras to record the plates. sends a notice to the legal diver autonomously. bines artificial intelligence with human39。s efforts.（4）What did a sixmonth test show? devices could help divers indeed. passenger helped operate the vehicles. drivers used electronic devices while driving. was mon to be busy with two wireless devices.【答案】 （1）D（2）C（3）D（4）C 【解析】【分析】本文是一篇說明文，介紹了澳大利亞新南威爾士州正在設置攝像頭，以減少開車時全神貫注于無線設備的人數。用這項技術懲罰那些因電話、社交媒體或短信分心的司機，將是世界上第一個。 （1）考查推理判斷。根據第一段“New South Wales, Australia, is setting up cameras as part of an effort to reduce the number of people preoccupied with wireless devices while they drive. It will be the first area in the world to use the technology to punish drivers distracted （分心） with telephone calls, social media or text messages.”澳大利亞新南威爾士州正在設置攝像頭，以減少開車時全神貫注于無線設備的人數。用這項技術懲罰那些因電話、社交媒體或短信分心的司機，將是世界上第一個。所以判斷出，新南威爾士設置攝像頭的真正目的是迫使司機更專注于駕駛。故選D。 （2）考查推理判斷。根據第二段中的“Road Safety experts are concerned about the growing number of accidents involving drivers using smart phones on the state39。s roads. They say drivers who use phones while driving greatly increase their chances of being involved in an accident.”可知道路安全專家對越來越多的司機在州內道路上使用智能手機的事故表示關注。他們說，司機在開車時使用手機，大大增加了發(fā)生事故的可能性。所以判斷出，道路安全專家認為急需采取措施禁止開車時使用手機。故選C。 （3）考查細節(jié)理解。根據第四段中的“The units use artificial intelligence to set aside drivers who are not touching their phones. Human beings then co
