It does, however, have its own problem.Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 5
2、0-kilometer race walk, which is about five miles longer than the marathon. But the sports rules require that a race walkers knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. Its this strange form that makes race walking such an attrac
3、tive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calo
4、ries(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runner
5、s hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.As a result, she says, some of the injuries associated with running, such as runners knee, are uncommon among race wal
6、kers. But the sports strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper t

B二（2020新课标D）The connection between people and plants has long been the subject of scientific research. Recent studies have
10、 found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Institute of
11、 Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when theyre short of water and a plant that can detect harmful chemicals in
12、groundwater. Were thinking about how we can engineer plants to replace functions of the things that we use every day,explained Michael Strano, a professor of chemical engineering at MIT.One of his latest projects has been to make plants grow(发光)in experiments using some common vegetables. Stranos te
13、am found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.in the future，the team h
14、opes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plants lifetime. The engineers are also trying to develop an on and offswitchwhere the glow would fade when exposed to daylight.Lighting accounts for about 7% of the total ele
15、ctricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.32. What is

19、ion, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Afr
20、ica and northern Europe have gained a mutation (突变) that helps them digest milk as adults.On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into
21、 better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, theyve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” sai
22、d Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than
23、us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”In201, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics
24、 that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.32. What does the author want to tell us by the examples in paragraph 1?A. Environm

A四（2020山东卷D）According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier peo
28、ple who order large portions(份), its the beanpoles with big appetites you really need to avoid.To test the effect of social influence on eating habits the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in
29、 a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weig
30、ht to 180 pounds.Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.For the second test, in one case the thin actor took two pieces of c
31、andy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.The tests show that the social environment is extremely influential when were making decis
32、ions. If this fellow participant is going to eat more, so will I. Call it the “Ill have what shes having” effect. However, well adjust the influence. If an overweight person is having a large portion, Ill hold back a bit because I see the results of his eating habits. But if a thin person eats a lot
33、, Ill follow suit. If he can eat much and keep slim, why cant I?12. What is the recent study mainly about?A. Food safety.B. Movie viewership.C. Consumer demand.D. Eating behavior.13. What does the underlined word “beanpoles” in paragraph 1 refer to?A. Big eaters.B. Overweight persons.C. Picky eaters

C五（2020浙江卷B）The traffic signals along Factoria Boulevard in Bellevue, Washington, generally dont flash the same length of green twi
36、ce in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.That
37、is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and c
38、ost of travels between work and home.“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.For all of Bellevues success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a res
39、earch engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “Its not going to fix everything, bu
40、t adaptive signals have some benefits for smaller cities,” he says.In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Trans
41、portation Departments traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.25. What does the underlined word “that” in paragraph 2 refer to?A. Increased length of green lights.B. Shortened traffic signal cycle.C
42、. Flexible timing of traffic signals.D. Smooth traffic flow on the road.26. What does Kevin Balke say about adaptive signals?A. They work better on broad roads.B. They should be used in other cities.C. They have greatly reduced traffic on the road.D. They are less helpful in cities seriously jammed.
43、27. What can we learn from Bellevues success?A. It is rewarding to try new things.B. The old methods still work today.C. I pays to put theory into practice.D.

44、er managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers memory and thinking skills
45、through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cog
46、nitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants overall health status.“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long run, yo
47、u may feel like youre in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. ”Its not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiters job, for example, that r
48、equires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And “running a family household requires high-level planning and coordinating(协调), ” she says. “You have to organize the activities of the children and take care of the bills and groceries. ”Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can
