21、Watching his father die without oxygen support while suffering from a heart attack in 2020, Taher Mahmud Tarif, a Bangladeahi boy, made up his mind to build a device to prevent any more such tragic deaths. Afterwards, many COVID-19 patients experienced low oxygen levels in their blood, with demand for oxygen concentrators (浓缩器) among other medical equipment shooting up during the recent sharp rise in cases. Tarif said the situation gave him more driving force to build the device.
With the financial and overall support of Ishwardi UNO office and his educational institution, Tarif's determination and tireless efforts were rewarded with success as the ninth grader of Ishwardi Sara Marwari High School managed to make the concentrator after trying five times for about seven months, mainly using domestic components. He said that a locally made oxygen eoncentrator like his costs approximately $ 760 whereas an imported one does over $2,600.
In June, Tarif gave a detailed account of his invention and manufacture at the UNO office in Ishwardi at 11:00 am on Tuesday. He said it was created from his own thinking and with the addition of local technology generators and electric components. An oxygen concentrator takes in air and removes nitrogen (氮气) from it, leaving oxygen-enriched gas for use by people needing medical oxygen. “About 90 percent oxygen concentration can be generated from my oxygen concentrator machine. This machine can provide high-flow oxygen supply too. It can be very handy in local areas with no scope of getting oxygen support,”Tarif added.
“This is obviously a good invention for oxygen generation. It is capable of producing high-flow oxygen so it can be used for patients or refilling oxygen bottles,” said an assistant professor of Pabna Medical College Hospital. “Despite more lab and other examinations before using the machine as medical equipment,” the UNO said, “Tarif's invention will probably be a great achievement during this alarming COVID-19 situation.”
【1】Why did Tarif build an oxygen concentrator?
A．Because his father needed one.
B．Because his father died of COVID-19.
C．Because COVID-19 patients need oxygen.
D．Because he wants to help save other patients.
【2】What can we know about Tarif's invention in Paragraph 2?
A．It mostly consists of local parts.
B．It succeeded at the first attempt
C．It was made without others' help.
D．It costs more than 2.600 dollars.
【3】What can we infer from the last paragraph?
A．Tarif's invention has not been tested yet.
B．Tarif's invention has a promising future.
C．Tarif's invention produces oxygen botles.
D．Tarif 's invention has proved useful for COVID-19.
【4】Where is this text most likely from?
A．A diary.
B．A brochure.
C．A newspaper.
D．A novel.
22、 Human beings learn technology from nature. They tend to imitate it. 【1】 It did take us a while to learn, though. However, not until the mid-twentieth century was the word “biomimicry (仿生学)” first introduced.
One of the first examples would be the invention of Velcro (魔术贴), a material that was born after a walk in the countryside by an engineer and his dog. On returning home, he found his socks were filled with little burrs (刺果). 【2】 They were covered by many tiny hooks (勾). He used those qualities for some kind of fabric. And then Velcro was born.
【3】 A high-speed train used to create great noise while exiting a tunnel because of the air pressure. Eiji Nakatsu, an engineer and bird-lover, was inspired by the kingfisher’s beak (鸟嘴), able to dive into the water at great speed with almost no friction, to create a new design. That’s how the modern bullet train, much more efficient and quieter, was born.
Secondly, there would be the imitation of Nature’s strategies and mechanisms. For instance, dolphins have mastered the art of sending out ultrasound (超声波) without disturbing each other. A team of researchers have analyzed the way dolphins adjust these frequencies. 【4】
Finally, there’s the imitation of the efficiency within an ecosystem. 【5】 For example, the street is full of tiny holes to empty water in flooding seasons and the foundations of buildings grasp the hillsides like the roots of trees.
A.One is the imitation of shapes.
B.People imitate forests to build cities.
C.For instance, birds taught people to fly.
D.He decided to get rid of these little burrs.
E.Then he bent down to inspect them closely.
F.Urban areas consume more energy than rural areas.
G.Based on the analysis, they designed a tsunami alarm system.
23、 When I was kid, I’d often come downstairs for breakfast and find my grandmother in the kitchen talking to herself, often going over what she was going to do that day. I thought it was the strangest thing. 【1】
Back then, I thought healthy people didn’t talk aloud when nobody else was around, did they? 【2】 It is a healthy, widespread behavior among children and adults. Research suggests the practice is most beneficial when it combines thought and action. Talking to yourself, when employed in the proper context, can even energize you mentally. Encouragement helps a person gain self-confidence and self-esteem, which contribute to success.
A study published in Psychology of Sport and Exercise had 72 tennis players take part in five rounds of play: one baseline assessment, three training sessions, and a final round. 【3】. Though both groups followed the same training program, only the experimental one was asked to practice self-talk. By the final assessment, the experimental group showed heightened self-confidence and reduced anxiety. The self-talkers also improved their game.
【4】 An in-depth analysis looked at the validity of the self talk strategy for improving athletic achievements. Totaling 32 sport studies and 62 effect sizes, it showed a positive, though moderate, effect size.
【5】 As Dr. Julia Harper, an occupational therapist said, “If we’re talking to ourselves negatively, research suggests that we’ll more likely guide ourselves to a negative outcome. However, when self-talk is neutral - as in a statement like ‘What do need to do?’ or positive, such as ‘I can get this done,’ then the outcome is much more effective.”
A．Researchers divided the players into two groups.
B．Participants with low self-confidence don’t like self-talk.
C．Unfortunately, human nature is ready for negative self-talk.
D．This effect only holds true if one’s self-talk remains encouraging.
E．These performance-energizing benefits aren’t just for tennis players either.
F．In fact, science has now shown that talking to yourself has a number of benefits.
G．Even though nobody else was around, hearing her would make me feel awkward.
24、Eugene Newman Parker, a leading figure in heliospheric(日球层的) physics for the past half century, passed away peacefully at his home in Chicago on Mar. 15. He was 94.
Hailed(誉为) as a visionary in the field of heliophysics, Parker revolutionized our understanding of the sun and its effects on Earth and other bodies within the solar system. NASA even stated that “the field of heliophysics exists in large part because of Dr. Eugene Parker. In 2018, Parker became the first living scientist to witness the launch of a spacecraft that was named in his honor.
Parker is best known for his groundbreaking theory on the existence of a phenomenon called “solar wind”, a continuous stream of charged particles that flow off the sun. It can become violent, causing space weather that impacts the Earth. When Parker’s research was published in 1958, his theory was initially met with skepticism(怀疑) and ridicule by the scientific community. The general view at the time was that the space between planets was an absolute vacuum(真空), and was thus completely empty of any matter. But, there were no errors in his study or his calculations, and the theory was later proven to be correct in 1962, when a NASA spacecraft mission to Venus revealed the constant presence of a supersonic wind—exactly as Parker had predicted.
That experience likely led to the advice Parker often gave young researchers: “If you do something new or innovative, expect trouble. But think critically about it because if you’re wrong, you want to be the first one to know that.” Parker never co-authored a paper with his students, thus urging them to be independent.
Parker was humble, straightforward, and wise. His son Eric said, “My sister Joyce and I didn’t get a real feel for what a ‘big dog’ our dad was in the field.” They got an even better sense when a month after Parker’s death, they traveled to Lund, Sweden, to accept on his behalf the Crafoord Prize in Astronomy.
【1】What can we learn from the second paragraph?
A．A spacecraft was named in memory of Parker.
B．The sun has less effects on Earth than expected.
C．Parker deserved credit for his great contributions.
D．NASA provided new insights into the lunar effect.
【2】Why did people view Parker’s theory of “solar wind” skeptically at first?
A．It went against the popular opinion at that time.
B．Some mistakes were found in his calculations.
C．The presence of a supersonic wind was proven by NASA.
D．Matter was believed to exist in the space between planets.
【3】What did Parker suggest young researchers do?
A．seek close cooperation
B．avoid high expectations
C．learn by trial and error
D．compete against others
【4】What words can be used to describe Parker according to the passage?
A．straightforward and generous
B．responsible and accessible
C．intelligent yet conservative
D．distinguished yet modest

26、Directions: Read the following passage. Summarize the main idea and the main point'(s) of the passage in no more than 60 words. Use your own words as far as possible.
These days, its not unusual to see middle-aged men collecting Star Wars action figures，office workers wearing Hello Kitty accessories, or celebrities like David Beckham playing with Lego bricks, it's becoming more and more common to see adult taking an interest in toys, comic books and the activities that are traditionally associated with children. This phenomenon has given rise to a new word: kidult.
What lies behind the phenomenon? One is about adults' nostalgia（怀旧）for the carefree days of childhood, and this is especially true with today's fast-paced, stressful lifestyles. Another is about a societal change in recent decades where people are starting families later. As a result, they have more time and money to spend on themselves. Some adults could only window-shop for their dream toys when they were kids, but now they can afford that radio-controlled car or high-priced doll they have always wanted.
Society traditionally disapproves of adults who refuse to put aside childhood interests, viewing the refusal as a sign of social immaturity （不成熟） and irresponsibility. Those who agree with this view sometimes claim that kidults are suffering from the pop-psychology concept known as Peter Pan Syndrome, an anomaly（异常）that people remain emotionally at the level of teenagers.
From the standpoint of kidults, though, this phenomenon is seen as nothing but harmless fun. Kidults insist that having youthful interests keeps them young, happy and creative, and their refusal to conform to society's acccptable tastes shows independent thinking. Besides, they argue that being part of the social trend of delayed adulthood is not purely a personal choice. The real causes include expensive housing, increased educational requirements for employment and poor work opportunities.
