新高考高一英语时文阅读专练（含答案解析）AIn a new report, infectious disease expert Jeffrey Shaman believes there were at least half a dozen stealth coronavirus cases to every one diagnosis at the start of the epidemic.The explosive spread of coronavirus was likely caused by ‘stealth transmissions’— undiagnosed people with mild symptoms unwittingly spreading the disease, a new study claims. Infectious-disease expert Jeffrey Shaman believes the actual number of contaminated worldwide is far greater than reports, estimating a million people may have been infected.The environmental health sciences professor at Columbia University who co-wrote the study published on Monday said social distancing is a must in order to combat seemingly healthy people spreading the virus. Despite only being half as infectious as the documented infections, these stealth cases resulted in at least two-thirds of documented infections, Professor Shaman and his colleagues said. Prof Shaman said this flip in the ratios meant about 60 percent of carriers were confirmed — but fast forward to now and new daily cases have significantly dropped from thousands to tens. The study says a “radical increase in the identification and isolation of currently undocumented infections would be needed to fully control” the novel coronavirus.People in the UK, meanwhile, have been told to avoid pubs, clubs and restaurants and work from home wherever it's possible to slow the spread of coronavirus which has now claimed 55 lives in the UK. Prime Minister Boris Johnson said at a press conference yesterday urged everyone to “stop non-essential contact and to stop all non-essential travel”. The PM said London appeared to be “a few weeks ahead” of other areas and urged people in the capital to pay special attention to the measures — including home working — suggested by the Government. The UK death toll yesterday rose to 35 while there have now been 1,543 cases. Health Secretary Matt Hancock yesterday said that over-70s could be asked to self-isolate for four months.Across the world more than 6,000 people have now died from the disease.1. How many people at least potentially got infected when one was diagnosed, according to Jeffrey Shaman?A. Twelve.B. Six.C. Seven.D. Ten.2. What’s the best way to prevent the spreading from undiagnosed people with mild symptoms?A. Wearing medical masks.B. Not going to work.C. Keeping a social distance.D. Sending these people to hospital.3. How does Professor Shaman consider the current control of the novel coronavirus?A. Cheerful.B. Uncertain.C. Depressing.D. Impossible.4. Which of the following is NOT the advice of UK government?A. To work at home instead.B. Not to go out for any dinner.C. To cancel unnecessary travel.D. To self-isolate for the aged.BSmart Cane Helps Identify the Blinds’ SurroundingsThis electronic walking stick is revolutionizing the way that blind people can navigate① the world.As a means of protecting people from low-hanging objects and obstacles above chest level, the WeWalk smart cane uses ultrasonic sensors to warn the user of nearby hindrances through vibrations② in the handle.The cane can be paired with a smartphone’s Bluetooth system for easy control. Since it is also integrated③ with V oice Assistant and Google Maps software, it can use built-in speakers to inform the user of nearby stores and infrastructural details that they may not be able to see.WeWalk CEO and co-founder Kursat Ceylan, who is also blind, told CNN that he helped to develop the cane out of a desire to use modern technology as a tool for the visually impaired.“In these days we are talking about flying cars, but these people have been using just a plain stick,” he told the news outlet.“As a blind person, when I am at the Metro station I don’t know which is my exit … I don’t know which bus is approaching …which stores are around me. That kind of information can be provided with the WeWalk.”The WeWalk is currently being sold for $500 a pop. As the Turkish tech startup gains more traction, the developers hope to eventually pair it with ridesharing apps and transportation services to further improve its navigational abilities.CThe rush to board the 17.46 from London Euston to Crewe begins the moment the platform is announced. The train’s eight carriages, in theory, each carry 70 passengers. But the London-Crewe line is Britain’s busiest rail service. It leaves Euston carrying, on average, more than twice as many passengers as it has capacity for. Sitting on the floor, Becky, a local government worker laments that, “It’s like this every day. I get a seat maybe once a week. And I pay five grand for this season ticket.”At peak times 19% of London rail users are forced to stand. The problems stretch across Britain: 17% are seatless at peak times in Birmingham and 15% in Leeds. With a poor punctuality performance by international standards and a high cancellation rate, commuting by rail in Britain is often a miserable experience. The government is now set to try to relieve some of the suffering with a major expansion of Britain’s rail network and a reorganization of the sector. More government money looks set to be coupled with more government direction.After the Victorian boom, the railways went into a long decline. Traffic fell for half a century after the Second World War. But over the past 25 years they have more than doubled: there were 1.8bn rail journeys in 2018-19, more than at any time since the early 1920s. But while in 1963 Britain had 17,500 miles of track, it now has under 10,000 miles.That is the root cause of much of the commuter woe. According to the Railway Industry Association track utilization is 60% higher in Britain than the EU average. According to Network Rail, the publicly owned manager of the track, around 70% of delays are the knock-on effects of congestion. The shrinkage of Britain’s network has also forced operators to run freight, intercity and commuter trains on the same stretches of track. The need to accommodate slower running stopping trains reduces the number of higher speed trains which can run on the same length of track.1. What does the example of Becky aim to tell us in Paragraph 1?A. The train has limited capacity.B. The ticket price is high.C. Standing on the train is uncomfortable.D. Train service should be improved.2. Which of following is NOT the reason why people suffer from commuting by railway?A. The trains are always late.B. Trains always get canceled.C. The capacity of train is small.D. Train arrangement is poor.3. What is the main reason behind poor punctuality?A. Shortage of track.B. Traffic jam.C. Too many passengers.D. Poor coordination.4. What is this passage mainly talking about?A. New railway expansion in Britain.B. Railway development in Britain.C. Problems of railway in Britain.D. Political measures taken by Britain.DPeace and Happiness Found in CleaningIn a recent survey of 2000 Americans, housecleaning was shown to have some mood-boosting effects—but that doesn’t mean everybody does it willingly.The majority of respondents said cleaning gave them a sense of accomplishment①(65%) and helped them clear their mind (63%).Half of these adults said they are most often motivated to clean when they’re happy. In fact, 63% of those surveyed find the experience of cleaning to be relaxing—even more so than getting fresh air (61%).But that’s not the only reason people clean.A whopping 70% admitted that tidying their home was a way of putting off having to do other things, with the average procrastinator②using that trick four times a week.The survey showed that 86% of respondents do feel on top of their chores, but the last deep clean of their kitchen happened over a week and a half ago. That’s no surprise because the kitchen is most dreaded of all.Conducted by OnePoll on behalf of DishFish, makers of multipurpose sponges and non-scratch scrubbers, the survey honed in③on people’s attitudes toward dirty dishes and how they get through the cringe④-worthy task.More than two-thirds of people (69%) let their dishes pile up between washings with 20%saying “always” letting them stack up in the sink, which left them feeling stressed.More than any other room, the kitchen was rated as “very difficult” to tackle. And most people enjoy scrubbing their toilet or taking out the garbage more than washing dishes by hand.How do they get through it? 66% listen to music while they clean.72% have a go-to song that they blast while tidying up their home, with “Uptown Funk,” “Read All About It” and “Work” being the three favorite tunes on America’s cleaning playlist.EA powerful and deadly storm moving through Middle Tennessee caused a tornado (龙卷风) that touched down in Nashville early Tuesday morning, cutting a swath of destruction that stretched through the city for miles.The storm destroyed parts of several neighborhoods and business districts in the central part of Nashville before moving into the city's eastern suburbs and beyond. Tornadoes impacted several counties in West and Middle Tennessee. In Putnam County, located more than 50 miles east of Nashville, 77 people were still missing, Putnam County leaders said at a Tuesday night press briefing. It's unclear how many of the missing people could be injured; many disasters have missing persons who eventually turn up unharmed. More than 30 people have been treated for storm-related injuries at Vanderbilt University Medical Center, hospital officials said Tuesday morning. Most appear to have been hurt by flying objects. Three people were killed in the Mt. Juliet suburb of Nashville. One couple in their 80s were killed at their home. James and Donna Eaton, 84 and 81, respectively, were identified by police about 5 p.m. Tuesday. Sheriff Kenny Christopher told The Tennessean that a couple living in a mobile home north east of Camden, were thrown into their yard where trees were blown down. Children were reported to be among the dead in Putnam County.Tuesday was the USA’s deadliest day for tornadoes since March 2, 2012. Sirens and cellphone alerts sounded, but the tornado that struck in the hours after midnight moved so quickly that many people in their path could not flee to safer areas. Some of the victims were killed in their beds. “It hit so fast, a lot of people didn't have time to take shelter,” Putnam County Mayor Randy Porter said. “Many of these people were sleeping.”The storm left “piles of rubble and the damage of buildings and neighborhoods,” Lee said Tuesday night. At least 140 buildings were destroyed by the storm, which left more than 50,000people without power Tuesday night. Roads, bridges and utilities were also damaged.1.Which one is NOT mentioned about tornadoes according to the passage?A.Areas of severe damage.B.Victims of the tornado.C.Causes of mass deaths.D.Statistics of property loss.2.What do we learn from the second paragraph?A.There is no child injured.B.All the missing people are alive.C.The number of injuries is uncertain.D.The elderly are the biggest victims.3.The last paragraph of the article intends to tell us that .A.tornadoes brings great damageB.people will live without powerC.it will take some time to rebuildD.the homeless should be given a hand4. Where would this passage most probably come from?A. A storybook.B. A newspaper.C. A guidebook.D. A report.A【答案】1-4 BCAB【解析】本文是一篇说明文，描述了英国新冠肺炎的现状，同时也把政府已经和即将采取的措施公布于众。
