26、 In the first days after a team of 25 delivery robots landed on George Mason University's campus in January,they appeared to cause curious glances and many photos but not much else.
It was clear,officials said,that more time and more data would be necessary to understand whether the robots would change the campus culture or become forgettable.Two months later,an extra 1,500 breakfast orders have been delivered autonomously,according to the technologists of Sodexo,a company that manages food service for GMU and works closely with the robots.
Research has shown that up to 88 percent of college students skip breakfast,primarily because of lack of time,but that number is starting to turn around when delivery robots arrive on campus.They're constantly seen making the 15 minute trip from campus restaurant to a handful of nearby dorms,as well as to other buildings across campus,where students meet them.Two months later,breakfast has replaced dinner as the go-to meal for robot delivery.
Sodexo officials have noted that college students are main users of food delivery apps and place a high value on convenience and multiple options when they dine.During the morning hours,restaurant experts say,there is generally more emphasis(强调)on speed than any other part of the day.Combine college students'love of food delivery with messy morning routines,and perhaps they have a perfect recipe for robots to deliver in the campus.
The robots also provide campus officials with valuable data showing how meal plans are being used,which could lead to changes in how the university serves students over time.Sodexo technologists also announced Monday that a new team of more than 30 robots is launching at Northern Arizona University.
【1】Why don't most college students have breakfast according to the research?
A.They are on diets.
B.They have a tight schedule.
C.The food doesn't agree with them.
D.GMU doesn't offer delivery services.
【2】What does the underlined word"they"in Para 4 refer to?
A.College students. B.Campus officials.
C.College professors. D.Restaurant managers.
【3】What do we know about the first 25 delivery robots?
A.They make timely deliveries.
B.They were ignored at first.
C.They mainly carry dinner at present.
D.They have changed the whole campus culture.
【4】What's the beat title for the text?
A.Delivery services grow fast in college.
B.Breakfast in necessary for college students.
C.Robots help with GMU's campus management.
D.Delivery robots are changing students'eating habits.
27、 We sacrifice our power of full presence when we're multitasking, and we do so for a benefit of improved productivity that simply doesn't exist. Multitasking is a myth(虚构的东西).
Research indicates that multitaskers are actually less likely to be productive, yet they feel more emotionally satisfied with their work. We're not actually accomplishing what we think we are — we've been fooling ourselves.
In fact, research also shows that multitasking, i. e. trying to do two cognitive (认知的)things at the same time, simply can't be done—the mind doesn't work that way. Even trying to do a cognitive activity and a more automatic activity at the same time doesn’t really work. That’s why the National Transportation Safety Board reports that texting while driving is the equivalent (等同之物)of driving with a blood-alcohol level three times the legal limit.
We believe we're effective at multitasking when in reality we’re good at what researchers call “task-switching”. Earl Miller, a professor at MIT, says, “Switching from task to task, you think you're actually paying attention to everything around you at the same time. But you're actually not.” The brain is forced to switch among multiple cognitive tasks as these tasks use the same part of the brain.
In fact, research indicates up to 40 percent of productivity could be lost due to task-switching. It actually takes more time to complete the tasks you re switching between and you make more errors than when you focus on doing one task at a time in order.
A Stanford study confirmed this by showing that those who multitask are indeed worse performers. Studies have shown that it takes four times longer for the brain to recognize new things, further slowing clown task completion and that we have a much lower retention (保留)rate of what we learn while we are multitasking.
【1】What can be inferred from the text?
A.Task-switching makes better performers at work.
B.We take multitasking for task-switching by mistake.
C.We feel good about what we do while multitasking.
D.Our brain focuses on different tasks when we multitask,
【2】What might Earl Miller agree?
A.We can't force our brain to multitask.
B.We should pay attention to everything around us.
C.We can occupy different parts of the brain with different tasks.
D.We shouldn't take texting while driving as the equivalent of drunk driving.
【3】For what purpose is the text written?
A.To introduce a new approach.
B.To compare different research findings.
C.To correct a common misunderstanding.
D.To analyze the consequence of a social phenomenon.
【4】What is the best title for the text?
A.Multitasking is a myth
B.Full presence is impossible
C.Cognitive tasks are time-consuming
D.Task-switching improves productivity
28、 It is one of the greatest mysteries of nature. In case you haven’t noticed, all living things follow very definite, individual rhythms, all as regular as a clock, but what makes them regular?
Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both, the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological “time clock.”
Take the mystery of migration for example. Scientists can’t really explain why many species of birds migrate in the autumn even though the temperature is still summery. The birds just seem to snub the comfortable weather that they are having. When a certain time comes, they travel south by the thousand. In spring time, they migrate northwards when though there probably is snow still covering the ground when they finally arrive. Something said “go”, and they did.
Animals that hibernate are obeying individual time clock, too. When their clock indicates the time to take a winter’s nap, they do, and nothing can stop them. At a certain time in the spring, they wake up and come out regardless of the weather outside.
Plants appear to have yearly rhythms, such as the sprouting(发芽)of seeds, and they also have daily rhythms. Notice sometimes that plants raise their leaves in daylight and lower them at night.
If you live along the California coast, you can easily observe a demonstration of this mysterious clock functioning regularly. There, from February to September, the highest tides occur exactly every fourteen and four-fifths days, and during these high tides, but at no other time, small silvery fish called grunions surf-ride a wave to the beach. There the female deposits her eggs in the sand and the male, fertilize them; then both hitch a wave-ride back to the sea. Exactly fourteen and four-fifths days later, never before or after, the tiny eggs hatch, and the high tide carries the new habits out to sea.
【1】According to the passage, the mysterious rhythms result from ________.
A.the influence of gravity on living species
B.the effect of radiation on living species
C.the influence of a mysterious outer force on living species
D.the internal mechanism inside the living species
【2】The underlined word “snub” in the third paragraph probably means ________.
A.fight B.ignore
C.symbolize D.criticize
【3】Which of the following statements is NOT TRUE?
A.Hibernating animals are obeying an internal time clock.
B.The positioning of the leaves of some plants is due to the daily rhythms.
C.The internal clock functioning is demonstrated in the reproducing habits of grunions.
D.The yearly hibernation is more because of the weather influence than the biological functioning.
【4】The passage is mainly about ________.
A.the rhythms of life B.the reasons of mysterious hibermation
C.strange behaviors of species D.the timing for different events in the world of species

THE DECLARATION OF INDEPENDENCE
In Congress, July 4, 1776
When in the Course of human events, it becomes necessary for one people to dissolve the political bonds which have connected them with another, and to assume among the Powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s god entitle them, a decent respect to the opinions of mankind requires that they should d【1】 the causes which impel them to the separation.
We h【2】 these truths to be self-evident, that all men are created e【3】, that they are endowed by their Creator with certain unalienable R【4】, that among these are life, L【5】, and the pursuit of Happiness.
That to secure these rights, g 【6】 are instituted among Men, deriving their just powers from the consent of the governed.
That whenever any form of Government becomes destructive of these ends, it is the Right of the P 【7】 to alter or to abolish it, and to institute new government, l【8】 its foundation on such principles and organizing its powers in such f【9】, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience has shown, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariable the same Object, evinces a design to reduce them under absolute Despotism, it is their right, it is their d 【10】, to throw off such Government, and to provide new Guards for their future security.

On a broiling afternoon when the men were away at work and all the women napped, I moved through majestic depths of silences, silences so immense I could hear the corn 【1】. Under these silences there was a / an orchestra of natural music playing notes no city child would ever hear. A certain cackle from the henhouse meant we had gained an egg. The creak of a porch swing told of a momentary breeze blowing across my grandmother’s yard. As I 【2】 along a mossy bank to surprise a frog, a 【3】splash told me the quarry had spotted me and slipped into the stream. Wandering among the sleeping houses, I learned that tin roofs crackle under the power of the sun, and when I tired and came back to my grandmother’s house, I padded into her dark cool living room, lay 【4】 on the floor, and listened to the hypnotic beat of her pendulum clock on the wall ticking the meaningless hours away.
I was enjoying the luxuries of a rustic nineteenth-century boyhood, but for the women Morrisonville life had few 【5】. Their lives were hard, endless, dirty labor.
For baths, laundry, and dishwashing, they hauled buckets of water from a spring at the foot of a hill. To heat it, they chopped kindling to fire their wood stoves. They boiled laundry in tubs, scrubbed it on washboards until knuckles were 【6】, and wrung it out by hand. Ironing was a business of lifting heavy metal weights heated on the stove top.
They scrubbed floors on hands and knees, thrashed rugs with carpet beaters, killed and plucked their own chickens, baked bread and parties, grew and conned their won vegetables, patched the family’s clothing on treadle-operated sewing machines, 【7】before the men to start the stove for breakfast and pack lunch pails, polished the chimneys of kerosene lamps, and even found time to tend the flowers that grew around every house. By the end of a summer day a Morrisonville woman had toiled like a serf.
At sundown the men drifted back from the fields exhausted and 【8】. They scrubbed themselves in enamel basins and, when supper was eaten, climbed up onto the porch to watch the night arrive. Presently the women 【9】 them, and the twilight music of Morrisonville began.
The swing creaking , rocking chairs 【10】 on the porch planks, voices murmuring approval of the sagacity of Uncle Irvey as he quietly observed for probably the ten-thousandth time in his life, “A man works from sun to sun, but a woman’s work is never done.”

Why Cold weather Causes So many Flight Cancellation?
Each year, about 60,000 flights get canceled because of bad winter weather, which costs airlines and airports an estimated $3 billion. But it’s not the freezing cold temperatures that cause problems for planes. After all, 【1】 jets fly 10 kilometers up, where temperatures hover around -50 degrees Celsius.
In fact, planes 【2】 in cold weather, since cold air is denser and leads to better thrust. Clearly, the real problem isn’t what’s going on up there. It’s what’s happening on the ground.
When a 【3】 polar vortex (极地涡旋) struck the Midwestern US in January 2019, temperatures dropped to -40 degrees Celsius and airline canceled 3,000 flights nationwide. In these situations, when temperatures start 【4】, everything slows down. Cargo doors can freeze up, along with the nozzles that pump fuel into planes, which delays the 【5】 process.
Even the plane itself can freeze over. Just a quarter-inch - thick layer of ice on a plane can disrupt the way air flows over its wings.
Les Westbrooks: The number one reason, I would say, that the reason flights get delayed in cold weather is going to be because there’s some kind of frozen precipitation, from frost to snow to a sheet of ice, adhering to the aircraft, adhering to the wings of the aircraft 【6】.
That’s Les Westbrooks, a retired airline pilot and an associate professor of aeronautical science at Embry-Riddle Aeronautical University. He says that 【7】, these planes are “de-iced” - but this also delays takeoff. The crew can spray the plane with a special hot water/ glycol mixture. It can take around 40 minutes to de-ice large passenger airplanes, so planes often have to wait “their turn” for the de-icing station, which, of course, can trigger more delays.
And ice on the runway, of course, creates another set of 【8】. In 2014, a plane at JFK skidded off an icy runway and into a mound of snow, leading to an hours-long shutdown at the airport. And even though crews can remove ice from the runway, scraping it off the pavement can lead to potholes (坑洞) and other 【9】, which makes takeoffs and landings more dangerous. And of course, snow and freezing rain on the ground can affect visibility to the point where officials have to decide it’s not safe to fly at all.
But if ice and snow aren’t the problem in these extremely cold temperatures, it’s usually another factor: people.
Les Westbrooks: The airplane flies at high altitudes, -60 degrees. It’s made to do that. Humans are not made to be outside in -60 degrees weather. And so the human factor becomes a big, big factor, when it becomes extremely cold.
Baggage handlers, aircraft fuelers, and mechanics all have to stay warm. Some airports, like O’Hare in Chicago, set up heated shelters for their employees. Of course, with everyone taking breaks to warm up, not as much gets done, which leads to even more delays and cancellations. Passengers start missing their 【10】 flights, and that, along with passengers who can’t make it to the airport due to bad road conditions, leads to half-empty planes.
In fact, many airlines might preemptively cancel flights before bad weather even hits. So, in the end, you can still blame cold weather for cancelling your flight.
