【文章內(nèi)容簡介】 uch vehicles is not clear among car makers, consumers and lawyers. “The liability(法律責(zé)任) issue is the biggest one of them all,” says Natasha Merat at the University of Leeds, UK.An assumption behind UK insurance for driverless cars, introduces earlier this year, insists that a human “ be watchful and monitoring the road” at every moment.But that is not what many people have in mind when thinking of driverless cars. “When you say ‘driverless cars’, people expect driverless cars.”Merat says. “You know — no driver.” Because of the confusion, Merat thinks some car makers will wait until vehicles can be fully automated without operation.Driverless cars may end up being a form of public transport rather than vehicles you own, says Ryan Calo at Stanford University, California. That is happening in the UK and Singapore, where governmentprovided driverless vehicles are being launched.That would go down poorly in the US, however. “The idea that the government would take over driverless cars and treat them as a public good would get absolutely nowhere here,” says Calo.12. The proposal put forward by Dobrindt aims to __________.A. stop people from breaking traffic rulesB. help promote fully automatic drivingC. protect drivers of all ages and racesD. prevent serious property damage13. What do consumers think of the operation of driverless cars?A. It should get the attention of insurance panies.B. It should be the main concern of law makers.C. It should not cause deadly traffic accidents.D. It should involve no human responsibility.14. Driverless vehicles in public transport see no bright future in __________.A. Singapore B. the UKC. the US D. Germany15. What could be the best title for passage?A. Autonomous Driving: Whose Liability?B. Fully Automatic Cars: A New BreakthroughC.

Driverless Cars: Root of Road Accidents第二節(jié) （共5小題；每小題2分，滿分10分）根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。 Everyanimal sleeps,but the reason for this has remained lab rats are notallowedto sleep,they die within a month. 16 . One idea is that sleep helps usstrengthennew memories. 17 .We know that,while awake,fresh memories are recorded by reinforcing (加強)connections between brain cells,but the memory processes that take place while we sleep have been unclear. Support isgrowing for a theory that sleep evolved so that connections between neurons(神經(jīng)元)in the brain can be weakened overnight,making room for fresh memories to from the next day. 18 .Now we have the most direct evidence yet that he is right. 19 .The synapses in the mice taken at theend of a period of sleep were 18 per cent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping.IfTononi’s theory is right,it would explain why,when we miss a night’s sleep,we find it harder the next day to concentrate and learn new informationour brains may have smaller room for new experiences.Their research also suggests how we may build lasting memories over time even though the synapses bee team discovered that some synapses seem to be protected and stayed the same size. 20 “You keep what matters,”Tononi says.A. We should also try to sleep well the night before.B. It’s as if the brain ispreservingits most importantmemories.C. Similarly, when people go for a few days without sleeping, they get sick.D. The processes take place to stop our brains being loaded withmemories.E. That’s why students do better in tests if they get a chance to sleep after learning.F.“Sleep is the price we pay for learning,”says Giulio Tononi, whodevelopedthe idea.G. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.
