三、阅读单选（本大题共15小题，每小题2分，共30分）
（A）
Feng Boyao and Meng Shuqi found that their city library didn’t have enough Braille books (盲文书籍) for blind people and many of the Braille books were outdated. So, they teamed up to help the blind by fixing the problem. Feng and Meng both studied at No 37 Middle School in Taiyuan, Shanxi province. They invented a new kind of Braille reader. Their work won first prize in a national competition aiming to nurture creative thinking by encouraging youths to solve social problems. The invention was also granted (授予) a national patent (专利).
When connected to a computer, their Braille reader can turn words into raised dots (凸起的点). Blind people can read by touching the dots, which are magnets (磁铁). This is the first Braille reader that uses magnets.
“We found that today’s Braille readers are very difficult and expensive,” Feng said. “So, we decided to develop a user-friendly product, especially for young blind children from grades 1 to 3. Moreover, it only costs about 2,000 yuan.”
After making their first device, Feng and Meng visited a school for the blind to get advice and improved it based on the students’ needs, like changing the size of the screen and the amount of space between the dots.
“We hope the invention will be popularized (普及) in the future to help those blind people who can’t afford the Braille reader now,” Meng told Taiyuan News.
31．Why did the two students invent a new kind of Braille reader
A．To get a national patent.
B．To hold a reading competition.

（B）
Two Swedish students have invented a new kind of bicycle helmet (头盔). It’s invisible (隐形的) because you cannot see it on a rider’s head.
The helmet is really a kind of airbag. It is inside a large collar (衣领). People wear it around their neck like a scarf. When the rider falls off his or her bike, the collar quickly fills with air and an airbag appears around the head.
The two students, Anna Haupt and Terese Alstinat, wanted to change the way people ride bikes. They said, “Bicycle helmets have always been the same. They’re so bulky, like a hard mushroom (蘑菇) on the head.” They called their new invention the H vding. The pair said it looked so cool that people would be happy to wear it.
The inventors started researching and developing the helmet a few years ago. They studied thousands of accidents. They wanted to find out how to make the safest helmet. They worked with a Swedish airbag company called Alva. And then the invisible helmet came out. Today, the two inventors have their own company that sells the new helmets. There are 17 workers in their company. They hope their helmet will change how people all over the world ride bikes.
In their video, Haupt and Alstinat said, “Cars are so yesterday. Bikes are the future.” People can not only take exercise but also experience the beauty of nature when they ride bikes. Now people can only buy the helmet online in Europe. It sells for around $530. The company did not say when people in the rest of the world could buy it.

（C）
Scientists in Switzerland have used lasers (激光) to change the path of a lightning strike (雷击的路径). The experiment suggests that in the future, lasers might be useful for protecting large buildings from lightning.
Lightning can be extremely powerful and cause serious problems on the ground. Lightning strike can cause fires, destroy buildings, and even kill people. The damage from lightning costs billions of dollars every year. In the US, lightning strikes killed close to 450 people between 2006 and 2021.
Scientists have been trying to find a way to protect buildings from lightning for a long time. Now the best Way is by putting metal rods (金属竿) on the buildings. These rods are connected to the ground. The lightning is attracted to the rods, which safely guide the electricity into the ground. But lightning rods can only protect a small area. Some buildings—such as airports are so large that it’s difficult to protect the whole building using lightning rods.
Another idea is to use lasers to guide lightning. Scientists had been working on the idea for over 20 years. They have successfully guided lightning with lasers inside a lab. But until the summer of 2021, scientists could guide lightning with lasers outside. Using a powerful laser, scientists in Switzerland were able to guide lightning tor meters.
The heat from the laser creates a path of air that is less thick than the air around it. The path also has a special charge (电荷). The lightning can follow this path almost as if it were a lightning rod. Scientist Matteo Clerici said, “The fact that we managed to do it in an outdoor environment is a very big step.”
But the laser still didn’t guide the lightning as far as the scientists would like. Besides, the laser is also very expensive. The scientists say it cost about $2 billion. It will probably take 10 or more years before a laser like this is truly able to protect large buildings.
41．To know how powerful lightning can be, which paragraph can we read
A．Paragraph 2. B．Paragraph 3. C．Paragraph 4. D．Paragraph 5.
42．What is the laser technology expected to protect
A．High-rise buildings. B．Large buildings.
C．Beautiful buildings. D．Important buildings.
43．Why are lasers not used widely for changing the path of lightning strike now
A．Putting metal rods on the buildings is the best way.
B．Some buildings are so large that it’s difficult to protect.
C．Lasers are only able to guide lightning for a short distance
D．Lasers are so expensive that scientists can’t pay for experimenting.
44．What can we learn from what Matteo Clerici said
A．Scientists still need to work harder to achieve a greater success.
B．It is not easy for scientists to guide lightning with lasers outside.
C．Scientists need to change working environment in next experiments.
D．It is a great progress for scientists to guide lightning with lasers outside.
45．What can we get to know at the end of the passage
A．Behind bad luck comes good luck.
B．A journey of a thousand miles begins with a single step.
C．There is still a long way to go before a laser can really work.
D．For scientists, working together is better than working alone.

71．范文：
Creativity is the key to human progress. Every major scientific discovery began with someone imagining the world in a creative way. With the development of society, it gets more and more important.
I am a big fan of science. Months ago, I wanted to make a model plane that could fly. At first, I thought it was easy. But during the process, I ran into many difficulties. Luckily, my science teacher helped me a lot and she advised me to search online and do a lot of reading. Finally, after two weeks’ hard work, my model plane could fly for two minutes.
Now I know if you want to create or invent something, you must increase your knowledge first. Or you can be hardly successful.
