DFrom an airplane, cars moving slowly down the highway look like ants. But actualants—unlike cars—somehow manage to avoid the suffering of stop-and-go traffic.Researchers are now studying these insccts’ cooperative tactics (战术) to learn how toprogram self-driving cars that don't jam up.The free flow of traffic becomes unstable as the number of cars increases on a highway.At 15 vehicles per mile per lane, one driver tapping their brakes (刹车) can cause aliquid to a solid form, says Nishinari, a physicist at the University of Tokyo.numbers. So what's their secret? In a recent study, researchers recorded ants on trails andjam because they travel in groups of three to 20 that move at nearly constant rates whilekeeping good distances between one another-—and they don't speed up to pass others.Human drivers at rush hour are hard to follow such rules. “"We're maximizing theinterests of individuals, which is why, at a given point, you start to have a traffic jam,” saysNicola, who studies sustainable engineering at the University of Trento in Italy. “Butself-driving cars, if they one day.become everywhere, could have more cooperative programming. In one vision of this future, autonomous vehicles would share informationand headways or by not passing others on the road," Nicola suggests.Today's drivers can learn at least one thing from ants to avoid causing a traffic jam,Nishinari says: don't tailgate. By leaving room between their car and the one ahead of them,drivers can absorb a wave of braking in heavy traffic conditions that would otherwise beamplified (放大) into a traffic jam with no obvious cause. “Just keeping away,"” he says,"can help traffic flow smoothly."32. What is paragraph 2 mainly about?A. The principle of causing a jam.B. The bad effects of jams on our life.C. The difficulty of avoiding a jam.D. The suffering of being stuck in a jam33. What is the ants' key to avoiding traffic jams?A. Traveling in large groups.B. Keeping steady speed and spacing.C. Following a central leader.D. Frequently walk over one another. 34. What does Nicola suggest in Paragraph 4?A. Provide more speed choices for drivers. B. Build special roads for self-driving cars.C. Set stricter rules to regulate drivers' behaviors.D. Apply ants’ cooperative strategies to self-driving cars.英语试题第7页共12页夸克扫描王极速扫描，就是高效品
