B Two Minds, Two Stories When we think of great inventors, two names often come to mind: Thomas Edison and Nikola Tesla. Both were brilliant, but their approaches to creativity were very different. Edison is known for his practical inventions, such as the light bulb and the phonograph. He believed in hard work and teamwork. He once said, “Genius is one percent inspiration and ninety-nine percent perspiration (汗水).” Edison had a large team of assistants and tested thousands of materials before finding the right one for the light bulb filament. His method was trial and error — keep trying until something works. Tesla, on the other hand, was a dreamer. He imagined his inventions in complete detail before building them. He is known for his work on alternating current (AC) electricity, which powers most of our homes today. Tesla preferred to work alone and often spent hours visualizing his ideas in his mind. He believed that a clear mental picture was more important than physical testing. Despite their differences, both men changed the world. Edison’s approach shows us the value of persistence and teamwork. Tesla’s approach reminds us that imagination and vision are also powerful tools. Perhaps the best way to be creative is to combine both — use your imagination to dream, and use hard work to make those dreams come true. 1．According to the passage, how did Edison and Tesla differ? A．One was American and the other was European. B．One worked in the 19th century and the other in the 20th. C．One focused on practical testing and the other on mental imagining. D．One invented the light bulb and the other invented the radio. 2．What does Edison’s famous quote “Genius is one percent inspiration and ninety-nine percent perspiration” suggest? A．Inspiration is more important than hard work. B．Hard work is more important than inspiration. C．Geniuses do not need to work hard. D．Perspiration is a waste of time. 3．How did Tesla often develop his inventions? A．By testing thousands of materials. B．By working with a large team. C．By visualizing them in his mind first. D．By copying Edison’s work. 4．The word “visualizing” in the third paragraph most probably means ________. A．drawing pictures B．building models C．forming mental images D．writing descriptions 5．What is the writer’s final suggestion about creativity? A．Only Edison’s method works. B．Only Tesla’s method works. C．We should combine imagination with hard work. D．We should choose one method and stick to it. C Many middle schools now hold “Idea Competition” every year to encourage students to think of creative ways to improve school life. 1 You don’t need to make a real product to join the competition — even a small smart idea is enough. Last year, 14-year-old Li Hua from No.3 Middle School noticed that students often forgot to take their umbrellas when it rained suddenly. 2 She suggested that the school put shared umbrella stands at each teaching building gate, with 20 umbrellas each. Students can take an umbrella for free when it rains and return it later. 3 Now the shared umbrella stands are already in use in her school, and almost 300 students have used them this term. Another student, Zhang Wei, found that the books in the school corner were old and not popular. 4 He suggested setting up a book exchange box: students can bring their old books to the box and take away other books they like. The idea was welcomed by both teachers and students. Now there are over 200 new books in the exchange box. 5 Even a small idea can make a big difference to your school. Next time you notice a small problem in your school, think about how to solve it — maybe your idea will become real too! A．He came up with an idea to make the book corner more popular. B．The competition asks students to find small problems in school and think of solutions. C．So she thought of a great idea to solve this problem. D．There are many other great ideas from the competition every year. E．Her idea was praised by the school headmaster immediately. F．Many students don’t like reading books at school. 【第六关】语法填空过关（共10小题，每小题1分，共10分） 阅读短文，用括号内所给词的适当形式填空。 Can you imagine a world without books, newspapers, or magazines?

Some inventions were created by accident, while others were the result of years of 1 . But one thing is common: all inventors were 2 and never gave up. Take the invention of the microwave oven as an example. In 1945, Percy Spencer was working on radar technology. He 3 that a chocolate bar in his pocket had melted. Instead of ignoring this, he 4 to find out why. He put some popcorn near the radar and it popped. This 5 to the invention of the microwave oven. Another example is the Post-it note. Spencer Silver was trying to develop a very strong glue, but he 6 created a weak one. For years, he didn’t know 7 to do with it. Then his colleague, Art Fry, used the weak glue to stick a bookmark in his hymn book. The bookmark stayed in place without damaging the pages. 8 they realized they had invented something useful. These stories show us that creative ideas often come from 9 . The key is to stay curious and open-minded.

Both were brilliant, but their approaches to creativity were very different. Edison is known for his practical inventions, such as the light bulb and the phonograph. He believed in hard work and teamwork. He once said, “Genius is one percent inspiration and ninety-nine percent perspiration (汗水).” Edison had a large team of assistants and tested thousands of materials before finding the right one for the light bulb filament. His method was trial and error — keep trying until something works. Tesla, on the other hand, was a dreamer. He imagined his inventions in complete detail before building them. He is known for his work on alternating current (AC) electricity, which powers most of our homes today. Tesla preferred to work alone and often spent hours visualizing his ideas in his mind. He believed that a clear mental picture was more important than physical testing. Despite their differences, both men changed the world. Edison’s approach shows us the value of persistence and teamwork. Tesla’s approach reminds us that imagination and vision are also powerful tools. Perhaps the best way to be creative is to combine both — use your imagination to dream, and use hard work to make those dreams come true. 1．According to the passage, how did Edison and Tesla differ? A．One was American and the other was European. B．One worked in the 19th century and the other in the 20th. C．One focused on practical testing and the other on mental imagining. D．One invented the light bulb and the other invented the radio. 2．What does Edison’s famous quote “Genius is one percent inspiration and ninety-nine percent perspiration” suggest? A．Inspiration is more important than hard work. B．Hard work is more important than inspiration. C．Geniuses do not need to work hard. D．Perspiration is a waste of time. 3．How did Tesla often develop his inventions? A．By testing thousands of materials. B．By working with a large team. C．By visualizing them in his mind first. D．By copying Edison’s work. 4．The word “visualizing” in the third paragraph most probably means ________. A．drawing pictures B．building models C．forming mental images D．writing descriptions 5．What is the writer’s final suggestion about creativity? A．Only Edison’s method works. B．Only Tesla’s method works. C．We should combine imagination with hard work. D．We should choose one method and stick to it. 【答案】1．C 2．B 3．C 4．C 5．C 【导语】本文对比了爱迪生和特斯拉的不同创造方式，最后建议将两者的优点结合——既要用想象力构思梦想，也要用勤奋努力实现梦想。 【详解】 1．本文明确说：“Edison is known for his practical inventions... Tesla, on the other hand, was a dreamer.”Edison以他的实用型发明而闻名……Tesla则相反，他是个梦想家。第2段详述Edison“trial and error”进行实际测试，第3段详述Tesla“visualizing his ideas in his mind”脑中想象。因此Edison和Tesla的不同之处在于一个注重实际测试，另一个注重脑中想象。 2．第2段提到“He believed in hard work and teamwork. He once said, ‘Genius is one percent inspiration and ninety-nine percent perspiration (汗水).’ ”Edison相信努力和团队合作，因此他说“天才=1%灵感+99%汗水”，明显强调努力比灵感更重要。 3．第3段提到“Tesla preferred to work alone and often spent hours visualizing his ideas in his mind”Tesla经常是通过脑中想象进行发明的。 4．第3段的“in his mind”和“He believed that a clear mental picture was more important than physical testing.”可知，visualizing的意思是在脑中形成心理图像。 5．最后一段最后一句：“Perhaps the best way ... is to combine both—use your imagination to dream, and use hard work to make those dreams come true.”明确建议结合想象与努力。 C Many middle schools now hold “Idea Competition” every year to encourage students to think of creative ways to improve school life. 1 You don’t need to make a real product to join the competition — even a small smart idea is enough. Last year, 14-year-old Li Hua from No.3 Middle School noticed that students often forgot to take their umbrellas when it rained suddenly. 2 She suggested that the school put shared umbrella stands at each teaching building gate, with 20 umbrellas each. Students can take an umbrella for free when it rains and return it later. 3 Now the shared umbrella stands are already in use in her school, and almost 300 students have used them this term. Another student, Zhang Wei, found that the books in the school corner were old and not popular. 4 He suggested setting up a book exchange box: students can bring their old books to the box and take away other books they like. The idea was welcomed by both teachers and students. Now there are over 200 new books in the exchange box. 5 Even a small idea can make a big difference to your school. Next time you notice a small problem in your school, think about how to solve it — maybe your idea will become real too! A．He came up with an idea to make the book corner more popular. B．The competition asks students to find small problems in school and think of solutions. C．So she thought of a great idea to solve this problem. D．There are many other great ideas from the competition every year. E．Her idea was praised by the school headmaster immediately. F．Many students don’t like reading books at school. 【答案】1．B 2．C 3．E 4．A 5．D 【导语】本文是一篇说明文，主要介绍不少中学每年举办“创意大赛”鼓励学生用巧思优化校园生活，列举两名学生的获奖创意落地案例，点明小想法也能给校园带来大改变。 【详解】 1．空前提到很多中学每年举办“创意大赛”鼓励学生想出改善校园生活的创意方法，空后补充说明参赛不需要制作实物产品，哪怕一个小小的巧思就足够，此处需要填入衔接大赛规则、承上启下的说明类内容。B项“The competition asks students to find small problems in school and think of solutions.”明确点出大赛的核心要求，既承接上文刚引出的Idea Competition的活动背景，又自然引出后文“不需要做实物、小想法就足够”的参赛规则补充，逻辑链条完全通顺。 2．空前描述李华观察到的校园痛点：下雨突然时学生总忘带伞，空后紧接着介绍她的具体解决方案——学校在每栋教学楼门口设置共享伞架，此处需要填入衔接“发现问题”和“提出方案”的过渡句。C项“So she thought of a great idea to solve this problem.”用逻辑连词So顺承前文的问题场景，自然引出后续的具体解决办法，人物行为逻辑连贯。 3．空前是李华提出的共享伞建议，空后说明现在伞架已经落地使用、本学期近300名学生用过，此处需要补充方案从提出到落地之间的正向反馈环节。E项“Her idea was praised by the school headmaster immediately.”解释了方案能顺利落地的前提：得到了校方的认可，衔接了“提出建议”和“落地使用”两个环节，情节发展符合校园场景逻辑。 4．空前描述张伟观察到的问题：校园角的书老旧、不受学生欢迎，空后文紧接着介绍他的具体方案：设立图书交换箱，学生可以自带旧书置换喜欢的其他书，此处需要填入衔接“发现图书角问题”和“提出图书交换方案”的过渡句。A项“He came up with an idea to make the book corner more popular.”直接点出张伟针对图书角的现存问题想出了优化创意，顺承前文的问题描述，自然引出后文的具体方案内容。 5．空前已经分别列举了李华的共享伞、张伟的图书交换箱两个大赛获奖创意案例，空后是全文主旨升华：哪怕小想法也能给校园带来大改变，号召学生发现身边问题尝试解决，此处需要填入对前文案例做扩展、引出主旨的过渡句。D项“There are many other great ideas from the competition every year.”说明除了前文列举的两个典型案例之外大赛还有很多优秀创意，既对前文的案例部分做了收束，又自然引出后文“小想法也能带来大不同”的普适性主旨，避免内容局限在两个个例上。 【第六关】语法填空过关（共10小题，每小题1分，共10分） 阅读短文，用括号内所给词的适当形式填空。 Can you imagine a world without books, newspapers, or magazines?
