26、 Almost all animals need to sleep to stay healthy. But sleeping can also be dangerous because other animals may hurt those who are sleeping. This leads to many different ways of sleeping that help them stay safe. Some of these ways may surprise you!
Almost all bats sleep upside down. They hang from a branch of a tree or the ceiling of a cave. Up high, bats are safe from most other animals. If they are in danger, they just fly away.
A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphin mothers and babies can go without sleep for as long as two months to stay safe.
Some ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help to keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep deeply with both eyes closed.
Seals breathe air, but that doesn't stop some of them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Sleeping deep underwater helps these seals stay safe from animals that hunt them near the surface.
Horses often sleep standing up. Their legs lock in place so they don't fall over. If a horse is lying down, it needs a long time to get up. A horse can run from danger more quickly if it is already standing.
A flamingo (火烈鸟) can sleep while standing on one leg. The standing leg locks so it stays straight. The other leg remains close to the flamingo's body. Its head rests on its back. A flamingo lives (and sleeps) near many other birds to stay safe.
Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air. They fly for many hours without flapping (拍打) their wings. Sometimes they sleep while they are flying.
Would you like to sleep how they sleep?

27、Gov. Kathy Hochul's proposal to allow restaurants to sell drinks to go with reasonable limitations was met with great enthusiasm all across New York. But New York's liquor (酒) stores have already begun a campaign of misinformation in an effort to block this.
Their basic argument is that the governor's proposal will result in an increase in underage sales, drunken driving, or any other public health problems. However, they throw these statements around without offering any support for their claims — because there is none.
While the liquor stores frequently claim that the laws have been unchanged since the abolishment (废除) of Prohibition in 1934, in just the past 20 years the rules governing liquor stores have been changed, permitting the use of online third-party delivery services and allowing stores to open on Sundays. Restaurant advocates didn't oppose these expanded privileges because they didn't have a significant impact on restaurant sales.
What hasn't changed of the law since Prohibition is the restriction on new liquor store licenses that give liquor stores a geographic territorial monopoly (垄断) to protect them from competition. Under typical circumstances, the State Liquor Authority will only issue a new liquor store license if the nearby stores report steadily increasing sales. However anti-competitive and outdated this restriction may be, it does serve as a protection against their concerns — in the very unlikely event they come to pass.
Economically, the pandemic has been a major help to the liquor store business. Before the pandemic, liquor stores sold 76% of all liquor in New York State and now they sell nearly 85%. And remember, during this period, restaurants were allowed drinks-to-go sales, showing their false claims of economic collapse are not grounded in reality or experience. The sales shift from restaurants to liquor stores over the past two years demonstrates clearly that restaurants have lost sales to liquor stores — we just want to stop the bleeding. While the restaurant industry rebounded for a part of 2021, employment still remains more than 20% below pre-pandemic levels.
【1】Why did liquor stores oppose the proposal according to the author?
A．Threat to public health.
B．Boost of underage sales.
C．Concerns about their sales.
D．Limitations to drinks to go.
【2】What can be inferred from the fourth paragraph?
A．Liquor stores are in a dog-eat-dog world.
B．Prohibition makes liquor stores dead in the water.
C．The number of liquor stores is under control.
D．What liquor stores worry about is reasonable.
【3】What does the underlined word “their” in the last paragraph refer to?
A．Restaurants.
B．Governors.
C．New Yorkers.
D．Liquor stores.
【4】What is the best title for the text?
A．Let restaurants sell drinks to go.
B．Defend liquor stores privileges.
C．Liquor industry is losing money.
D．Restaurants are racing with liquor stores.
28、 Starting the day on an egg could keep your blood pressure(血压) under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressurelowering drugs.
The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes(酶) they produce a protein that acts in the same way as ACE inhibitors, but more work is needed to show the effects outside a lab and in the human body.
Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol(胆固醇) found in eggs has little effect on increasing heart disease risks.
Researcher Professor Bruce Griffin, from the University of Surrey, said, “The wrong beliefs linking eggeating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods.”
The British Heart Foundation dropped its threeeggaweek limit in 2005. However, almost half of Britons believe the limit still applies.
【1】From the text we know that “ACE inhibitors” are________.
A.a kind of medicine B.a kind of protein
C.a kind of illness D.a kind of food
【2】According to what Professor Bruce said, eggs ________.
A.are the most nutritious food B.have no effect on blood cholesterol
C.can be included in a healthy diet D.are forbidden to be eaten in the UK
【3】The text is meant ________.
A.to introduce scientific findings about eggs
B.to introduce a medicine made from eggs
C.to tell people how to lower their blood pressure
D.to advise people to eat as many eggs as possible
29、 In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip(点滴)above her to fight her bone cancer. Over her bald(秃的)head, she wore a pink hat that matched her clothes. But the third grader’s cheery dressing didn’t mask her pain and weary eyes.
Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣,唱)birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling(蜷缩)in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.
【1】What do we know about Anita Kruse’s project?
A.It helps young patients record songs.
B.It is intended to kill time for patients.
C.It aims to replace the medical treatment.
D.It offers patients chances to realize their dreams.
【2】What does the case of a 12-year-old boy suggest?
A.Most children are naturally fond of music.
B.The project has a positive effect on young patients.
C.He was brave enough to put up performance.
D.Singing is the best way to treat some illnesses.
【3】What is probably the best title for the passage?
A.Purple Songs Can Fly B.Singing Can Improve Health
C.A Shining Moment in Life D.A Kind Woman—Anita Kruse

34、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
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.”

A huge milestone has just been reached in the field of artificial intelligence: AlphaGo, a program developed by Google’s DeepMind unit, has defeated legendary Go player Lee Se-dol in the first of five historic matches being held in Seoul, South Korea. Lee 【1】 after about three and a half hours, with 28 minutes and 28 seconds remaining on his clock. The series is the first time a professional 9-dan Go player has taken on a computer, and Lee is 【2】 for a $1 million prize.
“I was very surprised,”said Lee after the match.“I didn’t expect to lose. But I didn’t think AlphaGo would play the game in such a perfect manner.”DeepMind founder Demis Hassabis expressed“huge 【3】 for Lee Se-dol and his amazing skills.”calling the game“hugely exciting”and“very tense.”Team lead David Silver said it was an“amazing game of Go that really pushed AlphaGo to its 【4】.”
Go is an ancient Chinese board game that has long been considered one of the great 【5】faced by AI. While computer programs ow best the world’s leading human players of games like checkers and chess, the high level of intuition and 【6】required by Go has made it tough for computers to crack. DeepMind’s AlphaGo program is the most 【7】effort yet, using a complex system of deep neural networks and machine learning; it beat European champion Fan Hui last year, but Lee Se-dol is another 【8】 rival entirely.
“I don’t regret accepting this challenge,”said Lee.“I am in shock, I admit that, but what’s done is done. I enjoyed this game and look forward to the next. I think I failed on the opening layout so if I do a better job on the opening aspect I think I will be able to increase my 【9】 of winning.”Lee was surprised both by how strong AlphaGo’s opening was, and by some 【10】moves.

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.
