revolution in autonomous transport has significant meaning for wildlife as well.nature conservationists and planners need to think hard about the impact of driverless vehicles，especially in terms of the expanding of the cities.in some ways，wider developments in automotive technology are good for the environment.electric cars will increasingly replace the internal combustion engine(内燃机)，and that should，in theory，reduce carbon emissions and healthdisturbing air pollution.through minimizing traffic jams，driverless cars may also reduce energy use on the whole.unlike human drivers，computers can avoid needless acceleration and braking that worsen jams.and，as autonomous vehicles arent limited by human reaction times，it may make sense to increase speed limits for them on major intercity routes.so driverless cars promise a future of faster journey times with much reduced environmental impact！they may even mean less wildlife roadkill.but its the very efficiency of driverless cars that brings a challenge for planners and conservationists.the threat is an unchecked increase in lowdensity urbanization.autonomous vehicles promise a future in which passengers are free to use their time productively (working，for example).and they can park themselves，which saves yet more time in the morning rush.coupled with faster journey times，the motivation to live further out of town will increase significantly.there are both push and pull factors at work here：skyhigh residential prices in most cities push people away from city centres while healthy environments and green living pull people towards the countryside.the limiting factor in suburban(郊区的) spread is often travel time，either by public or private means.driverless cars completely change the situation.existing planning policies are based on our current transport systems.green belts，for example，are designed to reduce the expanding of the cities by restricting development within a buffer zone(缓冲地带) around an urban area.however，the reduced transport times offered by driverless cars make it easier to live outside the belt while still working inside.so these belts of green are in danger of becoming a thin layer in a sandwich of everspreading suburbanisation.this is，of course，a familiar challenge since the rise of the automotive age in the 1940s.however，the solutions designed by planners have been calibrated(标定) for a humandriving automotive systemnot for the supercharged future of driverless transport.other examples of planning protection for wildlife include nature reserves，national parks and (in the uk) “areas of outstanding natural beauty”.such areas have either strict control on development，or do not permit it at all.however，they are nice places to live in or nearby.the coming revolution in automotive journey times and the ability to work behind the (computerdriven) wheel will make living in such areas increasingly compatible(可共存的) with a journey to the nearest city.natural habitats(栖息地) being lost entirely or broken into eversmaller parts have long been understood as some of the primary causes of species disappearing across the world.the expanding of the cities threatens to increase the extent of both habitat deprivation and breaking.these threats are well known among conservationists，but there are differences in opinions on how best to respond.therere many problems in making humans move into cities，but the nearterm planning issues caused by autonomous vehicles will worsen the challenge given that they will lift demand to live in “unspared” lands.alternatively，some conservationists advocate “landsharing”，in which human communities redesign the way we farm and live so as to coexist with wildlife.autonomous vehicles bring significant challenges for either approach.whichever approach is taken，well need to redesign existing systems and policies to take account of the increased range that driverless transport speeds.this may involve new zoning laws to protect wider areas of countryside than at present.it certainly requires further development of green basic facilities and services，habitat corridors and “greenways”.it might also involve engineering solutions，especially given the fact that autonomous vehicles should be much more suitable to be driven underground.1.what does paragraph 2 mainly talk about?a.the future of driverless cars.b.the advantages of driverless cars.c.the working principle of driverless cars.d.the significance of designing driverless cars.2.what does the author think about driverless cars?a.they can greatly affect the way people work.b.they can minimize the risk of traffic accidents.c.they may cause change in peoples living places.d.they may attract more people to downtown.3.what does the author say about the green belt?a.it makes a valuable contribution to suburban spread.b.it is a necessary part of current transport systems.c.its importance is weakened by driverless cars.d.it is designed for environmental protection.4.what does the underlined word “deprivation” in paragraph 7 refer to?a.loss. b.shortage.c.protection. d.expansion.5.what is implied in the last paragraph?a.the landsharing approach gains widespread support.b.the countryside is a fit place for driverless cars.c.humans now coexist peacefully with wildlife.d.selfdriving cars need further development.6.whats the message conveyed in the passage?a.technology is the primary productive force.b.technology is a twoedged sword.c.save something for a rainy day.d.it is never too late to mend.佳作背诵(文娱与体育)假如你是学生会主席李华，为了让外国人了解中华民族传统文化，学生会面向学校国际部组织外国留学生报名参加“汉字听写大赛”，请你根据提示用英语写一则启事，在校报上刊登。主要内容包括：1.报名时请告知姓名和国籍；2.听写范围：中国四大名著中的词汇；3.参赛日期：2017年5月15日；4.奖品：一套中国古典名著；5.报名联系人：李华；电话：12345678910。注意：1.词数150左右；2.开头已为你写好，不计入总词数；3.可以适当增加细节，以使行文连贯。参考范文noticedo
