21、 Mary Nafula learned she had cancer a year ago. She survived the cancer treatment, but her hair fell out. The hair loss made the mother of three feel unprotected and weak. Nafula found help at a beauty salon in Nairobi. Women go to salons for haircuts and beauty treatments. But this business in Kenya's capital offers other products. It gave Nafula awig to cover her head. The wig replaces the natural hair she lost during the treatment.
Nafula describes her new feelings of confidence in herself. "We can take all the challenges that accompany us, knowing that we are going to heal," she says. Cancer deaths are rising from 37,000 reported cases in 2012 to almost 48,000 currently. Doctor Gladwell Kiarie is a cancer specialist at The Nairobi Hospital. She says the rise in cancer deaths is probably a result of lifestyle changes and more testing for cancer. "We are smoking more. We are taking alcohol more," Kiarie said. "Our traditional diets have changed. We have more fatty foods. We have less water and greens in our foods."
Nafula says she is happy to have a wig and to be free from criticism on the streets and in the public transport vehicles called "matatus." Nafula described being very sick and trying to ride in a matatu. She was told "You should not enter the matatu because cancer can infect us." Diana Akech is the owner of the beauty salon where Nafula got her wig. Akech started doing beauty makeovers （翻新）five years ago after a friend got cancer. The friend lost her hair, but Akech gave her a wig. "Let me say my friend gave me the willpower to keep doing this... She's in heaven right now and I am sure she's very proud of what I'm doing." Recovering from cancer can be long and painful. A wig can reduce the pain and show patients that they are not alone.
【1】What does the underlined “wig” in paragraph 1 mean?
A．A popular hat.
B．A beautiful mask.
C．A piece of artificial hair.
D．A pair of fashionable sunglasses.
【2】Why are cancer deaths rising recently in Kenya?
A．Because there are not enough beauty salons to offer special products.
B．Because testing for cancer causes people to suffer from cancers.
C．Because people in Kenya are too poor to be treated.
D．Because the unhealthy lifestyles mainly lead to more cancers.
【3】What can we infer from the passage?
A．People living with cancers in Kenya are usually discriminated.
B．Nafula has recovered from her cancer completely.
C．More and more people in Kenya will quit smoking.
D．Wearing a wig is the best way to treat cancer.
【4】What is the last paragraph mainly about?
A．A friend of Diana Akech dying of cancer.
B．The functions of wearing a wig.
C．The reason for the appearance of the wig.
D．The help from a friend to open a salon.
22、Parents around the world often urge children over and over-wash your hands! It can be difficult, however, to get children to remember to wash. But what if washing hands was connected to a fun creative activity? What if instead of simply reaching for the soap, a machine could drop it right into your hands?
Well, such a machine was recently built by a boy and his sister in the U.S. state of Maryland as part of a creative competition.The not-for-profit Rube Goldberg Organization is holding the competition.
Every year, the Rube Goldberg competition assigns a specific task, considering inventions that use complex systems to carry out a simple everyday task. At first, the task for 2020 was supposed to be “turn on a light.” But when the COVID-19 happened, the task was changed to “drop a bar of soap into someone’s hand.”
Those taking part in the competition are schoolchildren. But with schools closed to slow the spread of the virus, organizers changed the rules. This year, the team can include any family members and people were asked to send in recordings of the machines to compete. One thing has not changed: The machine must complete the task in less than 10 steps.
In Maryland, the Diel family wanted to enter. So, Caitlin and her brother Ben designed and built their own Rube Goldberg machine. Next, they had to demonstrate that it could complete the task-throwing the soap just right to be caught in someone’s hand. After 106 failed attempts, they finally had success. With their video demonstration, they can now enter the competition.
Dr. Anne Glowinski teaches child psychiatry (精神病学) at Washington University School of Medicine in St. Louis. She said that “creativity and play” connects with children. It is better than the message. “We have to wash our hands because of this horrible virus”. Glowinski added.
【1】What might be a task of inventions assigned by the Rube Goldberg competition?
A．Sweeping the floor.
B．Exploring nature.
C．Writing a novel.
D．Painting the house.
【2】What change has been made to the rules of the competition this year?
A．All kinds of inventions are admitted.
B．A video of the entry is qualified to enter.
C．Teachers are encouraged to get involved.
D．The task must be finished within 10 steps.
【3】What does Glowinski think of the invention?
A．Practical.
B．Unnecessary.
C．Economical.
D．Complicated.
【4】What’s the purpose of the text?
A．To advocate the habit of washing hands.
B．To call on schoolchildren to compete in a contest.
C．To encourage more inventions from everyday items.
D．To introduce a contest making handwashing fun for kids.
23、What's the attraction of coffee shops? It's been said that Jk Rowling wrote the Harry Potter books sitting in one in Edinburgh.
Many people spend hours in these places nursing a coffee as they work away on their laptops. But if you're spending all day buying one expensive coffee after another and haven't sold your first novel yet, the costs can really add up.
For those who work outside of a traditional office or just want to take time out, there's a new choice in London: a pay-per-minute cafe. You can stay for as long as you like in the Ziferblat coffee shop. You'll be given a clock when you come in to keep time. When you leave, you return the item and pay the bill.
The cost of hanging out, eating, working and meeting new people in the place is 3p per minute-or £ 1.80 an hour. The shop's owner, Ivan Meetin, says: “Everything is free, except the time you spend there”. Customers help themselves to coffee and cookies. They can also bring their own food to eat while accessing the internet through Wi-Fi.
Meetin's customers clearly are not the types who rush to work with a paper cup to drink from at their desks. They are there for the relaxed atmosphere. Informality(随性) is at the heart of Meetin' s concept. He's always loved the idea of building his own house. “With my mats, we were building treehouses where rules of society didn't exist,” he says.
Meetin believes his coffee shop is a bit like “social media”, but with a face Like-minded people go there to socialize. Some feel so much at home that they wash the dishes.
The concept of coffee shops, where you pay for the time and not for the cup, has proved popular in Russia. Only time will tell if the British will warm to the idea.
I'd like to try it at least once. Who knows-I might even start writing my own novel. If coffee shops are good enough for Jk Rowling to spend quality time in, why can't I?
【1】Which profession is known for working in coffee shops?
A．Scientists.
B．Journalists.
C．Novelists.
D．Nurses.
【2】How is his coffee shop similar to social media according to Meetin?
A．People meet others who share their interests.
B．People feel like spending quality hours there.
C．They provide people with a unique atmosphere.
D．They can be too expensive to use sometimes.
【3】What is the main idea of the text?
A．You can complete a lot of work in a cafe.
B．A new coffee shop charges people by the minute.
C．More and more money is being spent in cafes.
D．J. K. Rowling wrote her books in a cafe.
【4】What is the best title for the text?
A．Pay as You Sit
B．Enjoy Free Coffee
C．Come and Drink
D．Write in the Cafe
24、A major challenge for fully autonomous vehicles is navigating bad weather, snow especially. Averaging more than 200 inches of snow every winter, Michigan’s Keweenaw Peninsula is the perfect place to push autonomous vehicle tech to its limits. In two papers presented at SPIE Defense+Commercial Sensing 2021, researchers from Michigan Technological University discuss solutions for snowy driving scenarios that could help bring self-driving options to snowy cities like Chicago, Detroit, Minneapolis and Toronto.
Just like the weather at times, self-driving is not a sunny or snowy yes-no designation (指定). Autonomous vehicles cover a series of levels, from cars already on the market with blind spot warnings or braking assistance, to vehicles that can switch in and out of self-driving modes, to others that can navigate entirely on their own. Major automakers and research universities are still tweaking self-driving technology. Occasionally accidents occur, either due to a misjudgment by the car’s artificial intelligence(AI) or a human driver’s misuse of self-driving features.
Humans have sensors, too: our scanning eyes, our sense of balance and movement, and the processing power of our brain help us understand our environment. These seemingly basic inputs allow us to drive in virtually every scenario, even if it is new to us, because human brains are good at generalizing new experiences. In autonomous vehicles, two cameras scan and perceive depth using stereo vision to mimic human vision, while balance and motion can be gauged(计量) using a measurement unit. But computers can only react to situations they have encountered before or been programmed to recognize.
Since artificial brains aren’t around yet, task-specific artificial intelligence(AI) algorithms(计算) must take the wheel. Fisheye cameras widen the view while other cameras act much like the human eye. Infrared(红外线) picks up heat signatures. Radar can see through the fog and rain.
“All snow is not created equal,” Bos said, pointing out that the variety of snow makes sensor detection a challenge. “AI is like a chef -- if you have good ingredients, there will be an excellent meal,” he said.
【1】In what aspect is self-driving similar to the weather?
A．Both need assistance.
B．Both give warnings.
C．Both extend their limits.
D．Both have different levels.
【2】What might a computer fail to do?
A．Generalize new experiences.
B．Scan the unfamiliar environment.
C．Help vehicles achieve balance.
D．React to situations from memory.
【3】What does Paragraph 4 mainly focus on?
A．Artificial brains.
B．Fisheye cameras in cars.
C．Applications of Al.
D．The power of Radar.
【4】What does Bos want to convey in the last paragraph?
A．Bad weather discourages applications of Al.
B．AI has great potential to improve self-driving.
C．AI can help chefs to make wonderful meals.
D．Bad weather poses a challenge to sensor detection.
