I have never known an outstanding man who lacked either. And I have never known an average man who had both. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 14 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?” 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Fortunately, curiosity and discontent don't have to be learned. We are born with them and need only to 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 just follow the crowd. And the crowd desires only the calm and restful average. Most of us meet new people, and new ideas, with hesitation. But once having met and liked them, we think how terrible it would 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 have been, had we missed the chance. We will probably have to force ourselves to waken our curiosity and discontent and keep them awake. 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. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 The 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. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 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. 【解题导语】 本文是一篇议论文。文章探讨了好奇心和不满足感对成功的重要性，这两种深层次的人类驱策力比雄心壮志更重要。文章建议读者激发好奇心和不满足感，并勇于接触新事物和挑战传统，不断提高自己。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 1.What is the author's purpose in writing the first paragraph？( ) A.To present an argument. B.To make a comparison. C.To reach a conclusion. D.To propose a definition. 解析：写作意图题。根据第一段关键句“After years of observing human nature, I have decided...of average performance—curiosity and discontent.”可知，作者在第一段提出了文章的论点，告诉读者成就卓越的人和表现一般的人的区别在哪里。由此可推知，作者旨在提出一个论点。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 20 2.What does the example of Galileo tell us?( ) A.Scientists tend to be curious and ambitious. B.Trial and error leads to the finding of truth. C.Creativity results from challenging authority. D.Greatness comes from a lasting desire to explore. 解析：推理判断题。根据第二段内容可知，作者通过伽利略的例子告诉读者，好奇心和不满足这些驱策力，比有抱负重要得多，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。由此可推知，伽利略的例子告诉读者伟大来自对探索的持久渴望。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 21 3.What can you do to recapture curiosity and discontent?( ) A.Observe the unknown around you. B.Develop a questioning mind. C.Lead a life of adventure. D.Follow the fashion. 解析：推理判断题。根据第三、四段内容可知，唤起好奇心和不满足感，需要做与段落中相反的事，即要不满足于现状，勇于探索，勇于提出问题。由此可推知，通过培养质疑的思维来重新找回好奇心和不满足感。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 22 4.What can we learn from the last two paragraphs?( ) A.Gaining success helps you become an expert. B.The genius tends to get things done creatively. C.Lack of talent and time is no reason for taking no action. D.You should remain modest when approaching perfection. 解析：推理判断题。根据倒数第二段和最后一段可知，这两段强调的是不要因为自己没有时间和才能而不去采取行动，并建议读者记住没有比现在更好的开始时间，因为你永远不会比此刻更有活力。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 23 B 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 24 （2025·湖南多校期中联考）The Ig Nobel Prizes, established in 1991, are an amusing alternative to the distinguished Nobel Prizes, honoring research that “makes people laugh, then think”. The name is a clever wordplay on “ignoble”， meaning something lacking honor, reflecting the humorous and unconventional nature of the discoveries. However, beneath the foolishness often lies great scientific value, showing that curiosity can lead to significant understanding, even from seemingly insignificant questions. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 The prizes draw attention to a range of odd but fascinating studies. Last year, some researchers were awarded for demonstrating that real plants can copy the appearance of artificial ones they are planted alongside, revealing the remarkable adaptability of nature. Another study demonstrated that dead fish can swim upstream by using energy from fast-moving water currents, which could inspire energy-efficient designs in engineering. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Additionally, a probability experiment involving more than 350,000 coin throws revealed that a thrown coin is more likely to land on the side it started from, offering unexpected understanding into chance and probability. In previous years, similarly quirky studies have been honored. In 2004, one of the Ig Nobel Prizes was awarded to Jillian Clarke. She investigated the scientific soundness of the “five-second rule”, a popular belief that food dropped on the floor is still safe to eat if 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 picked up within five seconds. Some 2006 Ig Nobel Prize winners found that female malaria mosquitoes （蚊子） are equally attracted to the smell of human feet and Limburger cheese. This research, which won the Biology Prize, suggests that these odors could be used to develop innovative mosquito control methods. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Held annually in mid-September, around the time the real Nobel Prizes are announced, the Ig Nobel Prize ceremony is a unique mixture of humor and science, where real Nobel Prize winners present the awards. The event contains a number of running jokes, including Miss Sweetie Poo, a little girl who repeatedly cries out “Please stop, I'm bored”, if speakers go on too long. Paper airplanes are traditionally thrown by the audience, adding to the funny nature of the event. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 【解题导语】 本文是一篇说明文。文章介绍了搞笑诺贝尔奖的相关信息。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 30 5.What is the main purpose of the Ig Nobel Prizes?( ) A.To provide an alternative to the traditional Nobel Prizes. B.To recognize research that is purely humorous. C.To recognize humorous science research. D.To award the smallest scientific studies. 解析：细节理解题。根据第一段中的“The Ig Nobel Prizes...honoring research that ‘makes people laugh, then think’.”可知，搞笑诺贝尔奖的主要目的是表彰幽默的科学研究。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 31 6.What does the study of coin throwing reveal?( ) A.Possibility cannot be predicted with certainty. B.Human belief influences the probability of a result. C.The end result is always uncertain, with a 50/50 chance. D.Coins tend to land on the side they start from. 解析：细节理解题。根据第二段中的“a probability experiment involving...land on the side it started from”可知，对投掷硬币的研究表明，硬币落下时往往是它的初始面。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 32 7.What does the underlined word “quirky” in paragraph 3 probably mean?( ) A.Unusual or unconventional. B.Standard or typical. C.Boring or uninteresting. D.Disordered or unstructured. 解析：词义猜测题。根据第三段中的“In 2004, one of the Ig Nobel Prizes...within five seconds.”可知，获得此奖的研究都是奇怪的研究。因此，quirky意为“不寻常的、非常规的”。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 33 8.Who presents the Ig Nobel Prizes to the winners?( ) A.Scientists having a sense of humor. B.Political or social celebrities. C.Real Nobel Prize winners. D.Ig Nobel Prize organizers. 解析：细节理解题。根据最后一段中的“where real Nobel Prize winners present the awards”可知，是真正的诺贝尔奖获得者向获奖者颁发搞笑诺贝尔奖。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 34 C A fourth-grade star athlete has made headlines for keeping up with high schoolers. However,it's not for the honor. The selfless student is a guide runner for a blind autistic （患自闭症的） teen who needs a helping hand on the cross-country track. Rebel Hays,11,of Fayetteville,Arkansas,stepped up as a guide runner for a ninth-grader,Paul Scot,when West Fork High School put out a call for volunteers. Paul,their student,wanted to compete. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 35 As they ran together,the pair became good friends. “Paul and Rebel's story is so much more than running,” said Rebel's mother,Lou Ann. “Paul doesn't have many friends,so Rebel doesn't just guide him at races. They also spend time together,” she said,telling jokes. “Paul is grateful for his young guide's direction.” “Rebel directs me whether there's a ditch （沟） or there are hills,and he encourages me to run faster,” Paul said. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 In honor of their partnership,West Fork High School wrote a post on the Internet. Posting on Oct.6,after a 5K race at Chile Pepper where the boys achieved a personal record of 21 minutes,school representatives explained,“Rebel Hays has been helping Paul all season long. He is a promising runner,but more importantly,he has a huge heart! Thank you,Rebel! Thank you a lot!” 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 According to Mile Split Arkansas,Paul said that his goal this year was to break 21 minutes; however,they missed it at Chile Pepper but achieved it at Van Buren Pointer Classic,finishing with a time of 20:59:44.With the help and direction from Rebel,Paul finished 59th out of 135 runners in the 3A boys race at the state Meet in Hot Springs in early November. Paul still has one more year of eligibility （资格） for cross-country and has now set a new goal of under 20 minutes. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 【解题导语】 本文是一篇记叙文。文章讲述了失明的自闭症学生保罗在领跑员瑞贝尔的帮助下在多项比赛中取得胜利的故事。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 39 9.What did Rebel do as a guide runner to help Paul?( ) A.He competed with Paul to break records. B.He inspired Paul to make many headlines. C.He directed Paul at different races. D.He volunteered to tell jokes to Paul. 解析：细节理解题。根据第一段最后一句可知,瑞贝尔作为一名领跑员,帮助指导保罗参加不同的比赛。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 40 10.Which of the following can best describe Rebel?( ) A.Creative. B.Confident. C.Ambitious. D.Enthusiastic. 解析：推理判断题。根据第三段内容可知,瑞贝尔对保罗提供热情的帮助,说明他是个热情的人。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 41 11.Why did West Fork High School write a post on the Internet?( ) A.To claim Rebel to be promising. B.To express appreciation to Rebel. C.To draw public attention to Rebel. D.To introduce Rebel's achievements. 解析：推理判断题。根据第四段中的“Rebel Hays has been...Thank you a lot!”可知,西福克高中在网络上写了一篇帖子是为了向瑞贝尔表示感谢。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 42 12.What is Paul's plan for the following year?( ) A.Taking part in a 5K race at Chile Pepper. B.Directing others to finish the 3A boys race. C.Breaking the record of twenty minutes.
