A new study finds that these big-winged birdscarefully position their wingtips and flap (拍动) at the same rate, probably to catch the upward movement of air and save energy during flight.There are two reasons birds might fly in a V formation：It may makeflight easier, or they’re simply following the leader. Squadrons (中队) ofplanes can save fuel by flying in a V formation, and many scientistssuspect that migrating birds do the same. Models that treated flappingbirds like fixed-wing airplanes show that they probably save energy by drafting off each other, but currents created by airplanes are far more stable than those coming off of birds.Just as aerodynamic (气动力) calculations would predict, the birds positioned themselves to fly just behind and to the side of the bird in front, timing their wing flaps to catch the uplifting eddies (涡流). When a bird flew directly behind another, the timing of the flapping reversed (相反) so that it could minimize the effects of the downdraft coming off the back of the bird’s body.“We didn’t think this was possible，”Usherwood says, considering that the difficult achievement requires careful flight and incredible awareness of one’s neighbors. “Perhaps these big V formation birds can be thought of quite like an airplane with wings that go up and dow n.”]The findings likely apply to other long-winged birds, such as pelicans and geese, Usherwood says. Smaller birds create more complex wakes (尾波) that would make drafting too difficult.The researchers did not attempt to calculate the birds’energy savings because the necessary physiological measurements would be too invasive for an endangered species. Previous studies show that birds can use 20% to 30% less energy while flying in a V.Scientists do not know how the birds find that aerodynamic sweet spot, but they suspect that the animals line themselves up either by sight or by sensing air currents through their feathers. In future studies, the researchers will switch to more common birds, such as pigeons or geese. They plan to investigate how the animals decide who sets the course and the pace, and whether a mistake made by the leader can ripple through the rest of the flock to cause traffic jams.1．The author takes squadrons of planes for example to show ________.A．birds may save energy by flying in a V formationB．birds fly in a V formation for many more reasonsC．planes flying in a V formation follow the leaderD．planes flying in a V formation are more economical2．Why did Usherwood think it impossible for a bird to fly directly behind another?A．Because birds differ from airplanes in wings.B．Because birds know nothing about aerodynamics.C．Because birds could hardly create stable currents as planes.D．Because birds have to overcome great difficulties when flying.3．What is the scientists’attitude toward the findings mentioned in the passage?A．Cautious. B．Contradictory.C．Confident. D．Critical.4．What would the researchers do in their future studies about the birds?A．Calculate the birds’energy savings.B．Apply the findings to smallest birds.C．Find how the birds line themselves up.D．Do research on more common birds.Ⅲ.任务型阅读(2019·扬州中学高三英语摸底考试)In simple words, hibernation is a state of deep sleep. Hibernation differs from normal sleep in various ways. Hibernating animals take a long time to wake up from their sleep. Turning or kicking their bodies does not seem to wake them up. Even after waking up from hibernation, these animals take some time to restart their normal activities. During hibernation, the heart rate slows down and some of the non-vital organs become entirely inactive. This is a state in which the body uses very little energy.Winter is the time when food is less and weather is rough. Animals have to spend a lot of energy finding food. Even if they succeed in finding anything, it is often not enough to make up for the loss of energy. Besides, the cold weather may often become a cause of death. As a result of all these, animals have to reduce their food demand by reducing energy requirements. This is achieved by hibernating throughout the winter.Before the onset of winter, when there is plenty of food, animals eat overmuch and store much of the food in the form of fat. As winter arrives, they return to their home where they spend the rest of winter hibernating. As animals hibernate, their body temperature starts dropping due to lack of activity and metabolism (新陈代谢). At one point, it is only a few degrees higher than the surrounding temperature. Whatever energy the body needs to perform certain tasks is got from the fat storage. Due to lack of activity, the fat burning process is slow and steady. The energy from fat is enough to keep the animal alive for the rest of the winter.Hibernation differs for every species. For example, some animals like black bears may sleep for the whole winter without waking up, while animals like squirrels may wake up every 4 days to eat some food, pass waste matter from the body, and then go back to sleep. Hibernation in domestic animals may differ from that in the wild ones. As there is no food shortage for domestic animals, domestic animals hibernate as a result of their natural instinct but with more active periods in between.Hibernation答案Ⅰ.语篇解读：这是一篇记叙文。
