ories are recorded by reinforcing (加強(qiáng) ) connections between brain cells, but the memory processes that take place while we sleep have been unclear. Support is growing 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 form the next day. 38__ Now we have the most direct evidence yet that he is right. 39_ The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping. If Tononi‘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 information — our 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 thinner. The team discovered that some synapses seem to be protected and stayed the same size. _ 40_ ―You keep what matters,‖ Tononi says. A. We should also try to sleep well the night before. B. It‘s as if the brain is preserving its most important memories. 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 with memories. 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, who developed the idea. G. Tononi‘s team measured the size of these connections, or synapses, in the brains of 12 mice. 第三部分 語(yǔ)言知識(shí)運(yùn)用(共兩節(jié),滿分 45 分) 第一節(jié)(共 20 小題:每小題 分,滿分 30 分) 閱讀下面短文,從短文后各題所給的 A、 B、 C和 D 四個(gè)選項(xiàng)中,選出可以填入空白處的最佳選項(xiàng)。 and that if a human removes his or her hands from the driving wheel — to check , say — the car‘s maker is responsible if there is a crash. ―The change to the road traffic law will permit fully automatic driving,‖ says Dobrindt. It will put fully driverless cars on an equal legal footing to human drivers, he says. Who is responsible for the operation of such 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, introduced 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. 32. What does the phrase ―death valley‖ in Paragraph 2 refer to? A. A place where cars often break down. B. A case where passing a law is impossible. C. An area where no driving is permitted. D. A situation where drivers‘ role is not clear. 33. The proposal put forward by Dobrindt aims to __________. A. stop people from breaking traffic rules B. help promote fully automatic driving C. protect drivers of all ages and races D. prevent serious property damage 34. 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. 35. What could be the best title for passage? A. Autonomous Driving: Whose Liability? B. Fully Automatic Cars: A New Breakthrough C. Autonomous Vehicles: Driver Removed! D. Driverless Cars: Root of Road Accidents 第二節(jié) (共 5 小題;每小題 2 分,共 10 分) 根據(jù)短文內(nèi)容,從短文后的七個(gè)選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。 Tuesday 29 May, play will be performed by the National Theatre of China?
