26、As you walk around the UK in March, you might notice that some people are wearing a daffodil(水仙花) on their coats. The British wear these yellow flowers to show they support one of this country’s best-known charities: the Marie Curie Cancer Care.
The Marie Curie Cancer Care tries to ensure everyone diagnosed with cancer is cared for in the best possible way. It also helps fund research into possible cures through other organizations. Founded in 1948, it has been continuing with its goal ever since.
The charity was named after Marie Curie, a renowned scientist. She experimented with newly-discovered elements to create the theory of radioactivity. Unfortunately, over-exposure to the radioactive elements made her develop a disease and die in 1934. Marie Curie won the Nobel Prize in two different fields. Because of her pioneering work which led to chemotherapy (化学疗法), the charity shared the name of Marie Curie.
The daffodil is one of the first plants to flower during spring in the UK, which marks the return of flowering plants to the ecosystem after winter. Because of this, the charity uses the daffodil as a metaphor for bringing life to other people through charitable giving.
Everyone you see wearing a daffodil has donated money to the charity, but each daffodil is worth only what you want to pay for it. The charity does ask that you stick to a minimum amount of £1.
The charity encourages people to start wearing their daffodils at the start of March, when the “Great Daffodil Appeal” kicks off. But that doesn’t mean you can only wear them in March. People are sometimes seen walking around with daffodils on their clothes all year round.
【1】What does it mean when the British wear a daffodil on their coats?
A.They support a charity.
B.They are recovering from cancer.
C.They’ve been helped by a charity.
D.They’ve been diagnosed with cancer.
【2】What does the underlined word “renowned” in paragraph 3 mean?
A.Beautiful.
B.Modest.
C.Famous.
D.Humorous.
【3】Why was the charity named after Marie Curie?
A.Because patients required that.
B.Because it was launched by her.
C.Because she greatly supported it.
D.Because it could show respect for her.
【4】What can we learn about the daffodil from the text?
A.It can be used as medicine.
B.It’s thought to stand for hope.
C.It’s widely worn worldwide.
D.It’s sold to the wearers at a high price.
27、I was dropping my mom and sister off at the train station after their holiday visit. On the way I saw a man in a wheelchair in an empty car park. It looked like he wasn’t wearing shoes.
After dropping off my family, I went back to the park and he was still there. His chair was on the incline (斜坡) that led to the street and it looked like he was struggling with his bare (赤裸的) feet to keep the wheelchair from sliding (滑) away into the street. I asked if he wanted me to pull him back up. He nodded. I asked him to pick up his feet and pulled him back up into the park. He didn’t react when I asked if this was far enough. Then, I opened the box I had brought with me. It was a shoe box with an old pair of shoes that I had kept in my car in case I found someone in need.
You could imagine the look on his face. First it was shock, then it was pure delight. When he spoke, I couldn’t understand what he said, but I knew he was thanking me.
On the way back to my car, I saw a couple who were in need and gave them a couple of my bags for the homeless. As I drove past the first man, I saw he had already put on one shoe and was working on the second.
Keeping old pairs of shoes in my car for situations like this is so much more important than throwing them out or selling them at a yard sale.

28、Black holes were first put forward by Albert Einstein in 1916. However, scientists had not proved their directly. That changed on April 10, 2019, with the release of the first photo of a black hole in the center of the galaxy (星系)M87, located 55 million light years from Earth.
The photo does not show the black hole itself. That's because they are black and so they can't be seen in space.the scientists used radio signals to capture (拍摄)the black hole's "shadow" —the bright ring that forms around its edge, when light bends because of the extreme gravity around the hole.
The M87 black hole, believed to have a mass 6.5 billion times that of our sun, was captured using the Event Horizon Telescope (EHT)—a network of eight powerful telescopes(望远镜.)The telescopes,located in Hawaii, Arizona , Chile, Mexico, Spain and Antarctica, separately captured the black holl' s radio signals over four nights in April 2017, when the weather was fine in all six places. The data was transpcried to a centre where it was dealt with by a supercomputer to form the photo of the black hole's shadow. The researchers say while the photo is slightly blurry, future photos will be clearer as more telescopes are added to the EHT. Black ' holes are not easy to capture on camera because they are surrounded by thick dusty and hot gases.
Black holes are areas in space where the pulling strength of gravity is so powerful that even light is unable to escape. They can be different widely in size and mass. The smallest, called "primordial" black holes are as small as a single atom but with a mass of a big mountain. " Stellar' black holes, which are the most common, have a diameter (直径)of about 10 miles and a mass 20 times that of our sun. The largest or “supermassive' black holes, similar to that of M87's, can have a mass . greater than millions, or even billions of suns combined.
【1】What can we infer from the first paragraph?
A.Einstein's predicticn about black holes is right.
B.Einstein captured the black hole a century ago.
C.Scientists haven't proved black holes' presence.
D.The black hole has been known for centuries.
【2】What did the scientists use to capture the black hole's "shadow"?
A.Moon light.
B.Natural light.
C.Radio signals.
D.Sound waves.
【3】What does the underlined word “blurry” in the third paragraph probably mean?
A.Not big.
B.Not clear.
C.Not new.
D.Not attractive.
【4】What can we know about the M87 black hole?
A.It is almost empty.
B.It is the smallest one.
C.It is very bright.
D.It is very large.
29、 Airbnb is quickly becoming one of the biggest websites to book travel, which allows you to book a stay with individual hosts.
Benefits of booking a stay through Airbnb:
● Breakfast and snacks are often included in the price.
● You can arrange an early check-in or late check-out, space permitting, for NO extra charge.
● Many Airbnb places have a washer, full kitchen, and free internet.
● Travel with friends or family and stay together in one home.
● Stay in any part of town, NOT just where the chain hotels are located.
● Visit a unique destination where there are NO hotels.
● Meet lots of interesting people along the way!
Get a Better Price!
Because it's based on person-to-person interaction, you'll have lots of room to negotiate a better price.
1. Book Close to When You Want to Stay
Airbnb places get booked months in advance. Sometimes hosts find they have gaps to fill between stays, even up to the current day. In that case, the host might accept a lower offer. Send them a message and ask if there's a discount for booking the same week as your stay. Or even the same day!
2. Stay Longer
If you offer to stay a week or longer, some hosts are willing to offer discounts. That's because they won’t have to spend the costs of cleaning, laundry, and their time while you're staying.
3. Go in the Off-Season
Summer is the peak travel season for most of the US and Europe, especially if you're visiting a tourist destination. Hosts won't be as willing to negotiate because they know they can charge high rates. But if you want to stay between peak seasons, you might get a discount!
4. Offer Something in Return
Do you have a handy skill? Are you good at gardening, painting, or repairing things? Ask the host if they need help with changing light bulbs, fixing a leaky sink, or nailing down squeaky base boards. There are lots of ways that people can help each other. Where can you offer something in exchange for a discount?

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.
AI artwork sells for $432,500 — nearly 45 times its high【1】 — as Christie’s becomes the first auction house to offer a work of art created by an algorithm. This portrait, however, is not the product of a human mind. It was created by an【2】 intelligence, an algorithm defined by that algebraic formula with its many parentheses. And when it went under the【3】 in the Prints & Multiples sale at Christie’s on 23-25 October, Portrait of Edmond Belamy sold for an【4】 $432,500, signaling the arrival of AI art on the world auction stage.
From a distance, Portrait of Edmond de Belamy looks almost plausible. Up close, however, the paintwork becomes a grid of mechanical-looking dots, the man’s face a golden blur with black holes for eyes. Look into those eyes. They show no sign of feeling or life. Did a computer make this?
The answer is yes. The first artwork【5】 by AI to be sold at Christie’s, its【6】 price would seem to suggest that in future we will get computers to make art for us. Robot van Gogh will harmlessly cut its ear off and robot Picasso will be a genius.
Is this the future AI art visionaries such as the French collective Obvious, which programmed this “painter” by getting it to compare its own work with 15,000 pre-20th century portraits, have in mind? Or are they just, God forbid, making a fast buck from deceivable art collectors? Because believing the algorithm that knocked this up to be in any meaningful way an “artist” is like thinking your voice-interaction programme is out to get you. Dream on. Computers would need to replicate human consciousness before they could replicate the funny thing humans do called “art”.
Art is a way in which human 【7】 expresses itself, and is equally true of the earliest cave art, Rembrandt’s portraits and Duchamp’s urinal. And that is what is missing from Portrait of Edmond Bellamy. Art is a way humans communicate ideas, perceptions and feelings to each other. It has no 【8】 outside the human passion to communicate. So in what meaningful sense can an AI replica of certain【9】 traits of old master paintings be called art?
For a robot to really make art, it would need an autonomous mind that was emotional as well as【10】. No AI developer has yet claimed to be anywhere near achieving that and if they ever do, their creation will probably have better things to do than paint portraits — like destroy humanity.
Maybe afterwards robots will invent their own kind of art, but it won’t be some poor pastiche of human genius.
It will be beyond anything we organics could imagine.

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.

Tablets are really useful devices, but their big screens always make them a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit 【1】 into the hand?
Now something like a tablet-shaped but fold-able phone is about to become 【2】. In February, South Korean electronics company Samsung and China’s Huawei both unveiled fold-able phones Galaxy Fold and Huawei Mate X 【3】. Mobile phone use has entered the “fold-able future”, The Verge noted.
The technology could change our lives in significant ways. These devices, due to their 【4】 screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they’re “the 【5】 of a small tablets and smart-phone, all in a single device”.
The technology could 【6】 other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to 【7】 available space.
In a keynote address, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the fold-able screen “the 【8】 for the smart-phone of tomorrow.” “It’s a balank canvas for us to do something beautiful together,” he said.
So is there nothing to stand in the way of the fold-able future?
According to tech news website Android authority, the necessary displays were difficult to produce. In 2012, nine out of every to OLED screens produced were 【9】. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these fold-able devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that may 【10】 the majority of people.
But if the fold-able device isn’t going to change the world overnight, there is no doubt that it is coming.
Patrick Moor-head, an industry analyst told The Verge, “Few are debating if fold-able or roll-able mobile displays are the future of smart-phones; the only question is when and by whom.”

Finding Your Courage
Gold and brown leaves crunched(吱吱响)under Dora's boots as she made her way down the sidewalk. She could not wait to be home. The chill(寒冷)from the autumn winds was bad, but it was not nearly as hard to bear as the chill she felt in her heart.
She could not forget the way she had frozen in front of the class today. Mr. Roberts divided the class into groups to do presentations. Each person in the group would speak for five minutes in front of the class. Today was Dora's turn. Her legs trembled(颤抖)all the way to the front of the classroom. Her hands shook so badly that she could not read her notes. As Dora spoke, her voice became softer, almost to silence. Mr. Roberts kindly ended Dora's part of the presentation even though she had clearly not finished. He also asked Dora to stay after class for a moment.
“Dora, I know you're shy, but you worked hard on this project. I'd hate to see you give up on yourself. ” Mr. Roberts suggested, “If I give you another chance tomorrow, do you think you can find your courage?”
Dora nodded. She went as quickly as she could to her next class. She kept her head down and hoped the school day would end soon.
Arriving home, she found Mom baking in the kitchen. When Mom baked, Dora always watched and chatted with her. Mom always said it was Dora's company that made her baked goods taste so sweet.
Mom studied Dora's face as she came into the kitchen. “What's wrong, Dora?"
Tears shone in Dora's brown eyes. She told the whole story. Mom was silent for a moment, but her hands still busy with the cake.
“Why is it that you can talk to me about anything and everything, but you can't talk to your class?" Mom asked, sliding the round cake pans into the oven. She set the timer and then said, “Let me show you something. ”
Paragraph 1:
Dora followed Momma to her bedroom.
