Short and shy, Ben Sanders was the last kid in his class picked for any sports team. “Football, tennis, cricket—anything with a ground ball, I was useless,” he says now with a laugh. But back then he was the object of jokes in school gym classes in England’s rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Sanders set his mind building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Sanders was hired as an instructor at Ridgway’s school of Adventure in Scotland, where he learned about the older man’s brave and exciting cold-water travels. Intrigued,Sanders read all he could find about Arctic explorers and North Pole expeditions, and then decided that this would be his future.
Journeys to the Pole aren’t the usual holidays for British country boys, and many people thought of his dream as fantasy. John Ridgway was one of the few who didn’t say, “You are completely crazy.”
In 2001, after becoming a skilled skier, Sanders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a close encounter with a polar bear and pushed his body to the limit. Sanders has since become the youngest person to ski alone to the North Pole, and he has skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Sanders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.
4. The turning point in Sanders’ life came when __________.
A. he started to play ball games
B. he got a mountain bike at 15
C. he ran his first marathon at 18
D. he started to receive Ridgway’s training
5. What do we know about Ridgway?
A. He considered Sanders’ dream unrealistic.
B. He built up his body together with Sanders.
C. He hired Sanders for his cold-water travels to the Arctic.
D. He established his reputation by his voyage across the Atlantic.
6. The underlined word “Intrigued” in Paragraph 3 probably means __________.
A. Fascinated
B. Grateful
C. Frightened
D. Pleased
7. According to the passage, Sanders’ journey to the North Pole __________.
A. made him well-known in the 1960s
B. was favored by other Artic explorers
C. was accompanied by his old playmates
D. set a record in the North Pole expedition

In the Amazon rainforest of Venezuela, Yanomami hunter-gatherers exist on cassava, palm hearts and wild bananas. They also hunt frogs and monkeys using techniques that would have been familiar to their ancestors 11,000 years ago. The extraordinary continuity of their culture, and the fact that some of the groups have had little contact with outsiders, led biologists to wonder whether the Yanomami might reveal what the human digestive system looked like before industrialization supplied the world with processed foods and antibiotics.
In 2019, researchers at the Icahn School of Medicine had a chance to find the answer in a previously unknown Yanomami village. Health workers collected feces (排泄物) from about 30 villagers. When the researchers cultured and analyzed microbes (微生物) from the feces in their laboratory, they discovered whole categories of bacteria that were absent from the guts (肠道) of people from industrialized countries. Even more strikingly, they found the microbial population in
the average Westerner to be about half as diverse as the community inside these hunter-gatherers. The researchers realized that the microbes might have implications beyond basic science. People’s microbial communities are believed to play a role in disorders like obesity, diabetes and Alzheimer’s, which shorten lives and overburden health care systems. These disorders don’t trouble these preindustrial hunter-gatherers, however. Therefore, researchers want to learn which microbes protect them and figure out how to reintroduce them in modern societies. It has the potential to affect health more profoundly than the discovery of the fabled Fountain of Youth.
But the opportunity might be more fleeting than youth itself.“The world is becoming urban so fast.” says microbiologist Maria Gloria, co-author of the study that reveals the Yanomami microbiome (微生物群). “Our lifestyles are killing microbial diversity.” Although nobody has yet determined exactly what the Yanomami mystery bugs are doing and how they improve an individual’s health, she believes that scientists need to collect and preserve as many microbes as possible for future breakthroughs. “We cannot afford to wait,” she says, “or we’ll have lost the high diversity of the human microbiome of traditional peoples before we understand how to use the microbiome to improve health.”
8. What did the researchers find out in 2019?
A. The hunter-gatherers had a different digestive system.
B. Microbial communities were to blame for many disorders.
C. People from industrialized countries had less diverse microbes.
D. Some categories of bacteria did not exist in the villagers’ guts.
9. How did the researchers make their discovery?
A. By collecting health data.
B. By conducting experiments.
C. By interviewing the villagers.
D. By recording the Yanomami’s daily life.
10. What does the author mean by “the opportunity might be more fleeting than youth itself”?
A. The opportunity seems more precious than youth.
B. The opportunity enables people to stay young forever.
C. The opportunity is of great significance to modern society.
D. The opportunity disappears so quickly that we cannot afford to miss it.
11. What can be inferred from the passage?
A. We are close to solving the mystery of Yanomami microbiome.
B. Processed foods and antibiotics have changed human digestive system.
C. Treating diseases by introducing beneficial bacteria has been made possible.
D. The discovery of those microbes will help cure many life-threatening diseases.
『答案』8. C 9. B 10. D 11. B

D
After years of observing human nature, I have decided that two qualities make the difference between men of great achievement and men of average performance: curiosity and discontent. I have never known an outstanding man who lacked either. And I have never known an average man who had both. The two belong together.
Together, these deep human urges (驱策力) count for much more than ambition. Galileo was
not merely ambitious when he dropped objects of varying weights from the Leaning Tower at Pisa and timed their fall to the ground. Like Galileo, all the great names in history were curious and asked in discontent, “Why? Why? Why?”
Fortunately, curiosity and discontent don’t have to be learned. We are born with them and need only recapture them.
“The great man,” said Mencius, “is he who does not lose his child’s heart.” Yet most of us do lose it. We stop asking questions. We stop challenging custom. We never doubt.
We just follow the crowd that desires only the calm and restful average. The crowd encourages us to occupy our own little corner, to avoid foolish leaps into the dark, to be satisfied. We will have to force ourselves to do just the opposite so as to waken our curiosity and discontent.
How should you start, modestly, so as not to become discouraged? I think of one friend who couldn’t arrange flowers to satisfy herself. She was curious about how the experts did it. Now she is one of the experts, writing books on flower arrangement.
One way to begin is to answer your own excuses. You haven’t any special ability? Most people don’t; there are only a few geniuses. You haven’t any time? That’s good, because it’s always the people with no time who get things done. Harriet Stowe, mother of six, wrote parts of Uncle Tom’s Cabin while cooking. You’re too old? Remember that Thomas Costain was 57 when he published his first novel, and that Grandma Moses showed her first pictures when she was 78.
However, you start, remember there is no better time to start than right now, for you’ll never be more alive than you are at this moment.
12. In writing Paragraph 1, the author aims to ________.
A. give an example
B. present an argument
C. propose a definition
D. make a comparison
13. What does the example of Galileo tell us?
A. Trial and error leads to the finding of truth.
B. Creativity results from challenging authority.
C. Greatness comes from a lasting desire to explore.
D. Ambition is more important than curiosity and discontent.
14. What can you do to recapture curiosity and discontent?
A. Lead a life of adventure.
B. Follow the fashion.
C. Develop a questioning mind.
D. Observe the unknown around you.
15. What could be the best title for the passage?
A. The Keys to Achievement
B. Never Too Late to Learn
C. Curious Minds Never Feel Content
D. Reflections on Human Nature
『答案』12. B 13. C 14. C 15. A
『解析』

Galileo was not merely ambitious when he dropped objects of varying weights from the Leaning Tower at Pisa and timed their fall to the ground. Like Galileo, all the great names in history were curious and asked in discontent, “Why? Why? Why?””（总的来说，这些人类的强烈欲望比雄心壮志更重要。

当伽利略从比萨斜塔上扔下了重量不等的物体，并测定了它们落在地上的时间时，他不仅雄心勃勃。

像伽利略一样，历史上所有伟大的人物都很好奇，并不满地问道：“为什么？为什么？为什么？”）可知，作者通过伽利略的例子告诉我们人类的强烈欲望比雄心壮志更重要，历史上所有伟大的人物，他们的成功正是因为对事
物的好奇和不断探索。

由此可知，伽利略的例子告诉我们伟大来自对探索的持久渴望。

人群鼓励我们占据自己的小角落，避免愚蠢地跳入黑暗，要满足。

我们将不得不强迫自己做相反的事，以唤起我们的好奇心和不满。

）可知，要唤起我们的好奇心和不满，我们需要做与段落中相反的事，也就是我们要不满足于现状，勇于探索，勇于提出问题。

由此可知，你能通过培养质疑的思维来重新找回好奇心和不满。

故选C项。

『15题详解』

选项中有两项为多余选项。

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. ___16___
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the
thinking stage and go straight for the scale (秤) instead. ___17___ On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain and that life can be without resistance and struggle.
___18___ Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients (营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional. ___19___ Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them to reduce weight. ___20___ Once we realize this, we will be much better able to resist diet products, and therefore prevent the harm that comes from using them.
A. It’s believed diet products contribute to losing weight.
B. Chemicals that go into diet products are potentially dangerous.
C. We all know the danger of diet products, but it’s hard to resist them.
D. The danger of diet products lies also in the physical harm they cause.
E. We are paying for products that harm us psychologically and physically.
F. Losing weight lies in the power of minds, not in the power of chemicals.
G. All we have to do is to swallow or recognize the word “diet” in food labels.

减肥产品让我们跳出思考阶段，直接去量秤。

)”可知，本段介绍了减肥产品错误的引导我们只要能减掉体重就是减肥，让我们忽略掉真正的减肥是控制脂肪、高热量、不健康食物的摄入，G项意为“我们所要做的就是吞咽或识别食品标签上的“饮食”一词。

”选项内容能够承接上文，我们不再思考什么是真正的减肥，只是识别食品标签上的“饮食”一词，只要标注着是减肥食品，我们就吃下去。

故选G。
