What Middle School Kids Can Do！
SmartWander Sock When he was 14, Ken decided to find a way to help his grandfather, who suffered from Alzheimer's disease(阿尔茨海默病). He noticed his grandfather might get hurt, or he could walk around and get lost. Ken invented SmartWander socks to remind family members whenever his grandfather started moving. The idea worked well and became popular. Solar-Powered Tent Daniela remembered the homeless people she saw on her way to school when she was around age 14. Looking for a way to help them, she worked together with 12 other teenage girls to invent a solar-powered tent. Their tents provided shelter and a source of power for the homeless and for people affected by natural disasters. Tethys Water Tester A 12-year-old girl named Rao invented a device(仪器) to test drinking water for lead(铅). She learned about a town in Michigan where the drinking water was dangerous. When people drank the water, it caused serious health problems. She wanted to help them. Her invention was faster, less expensive, and easier to make than other methods. Lion Lights At age 11, Richard invented a simple, low-cost, solar-powered device that safely drove hungry lions away from his family's goats, cows and sheep in Kenya. He noticed that the lions did not come near when he was holding a torch at night to check on the livestock(家畜). He then invented a series of flashing LED lights and spaced them around the livestock pens. His invention was good enough to help many other people in his community and also avoided having to hurt the lions.

①Nowadays, the shared bikes are getting more and more popular in China. Experts in China say there are three reasons behind the popularity: a lot of money looking for a home, a good idea and government support.
②Since March 2015, two companies—Mobike and Ofo have attracted $750 million in private investment(投资) from China and overseas, most of which in recent months.
③But easy money is only part of the story, according to Wang Chenxi, a Chinese expert: “Although behind this is the push of capital(资本), shared bikes are a good product. __▲__ The user simply opens a mobile app, locates the nearest bike, and unlocks the bike by scanning the QR code(扫描二维码) with his or her smart phone. Many young people fall in love with it. All in all, capital needs a chance, and just at that moment, shared bikes came along.”Cai, the Ofo spokeswoman, also said the company thought that as the city's population grew, and traffic jams got worse, shared bikes could solve the problem in an environment-friendly way.
④“The most important reason for the speed and scale(规模) of the investment in the bike-sharing system is the government support，”said Lin Chen, a professor at the China Europe International Business School. Actually, the government has created special lanes(车道) for bicycles where cars are not allowed, adding bicycle signs to the traffic signs. And to better regulate shared bikes, the government has set new guidelines in August to keep the bike-sharing system on track(轨道) and avoid random parking outside subway stations that sometimes leads to crowded sidewalks. Besides, due to safety concerns, children under the age of 12 are not allowed to use the bikes. The bike-sharing business is well organized in big cities with the government support.
5．Which of the following is the best for “__▲__” in Paragraph 3
A．Shared bikes need to be protected.
B．Shared bikes also cause problems.
C．It's difficult to use a shared bike.
D．Using a shared bike is easy.
6．The underlined word “random” in Paragraph 4 means “________”．
A．predictable B．enjoyable
C．casual D．formal
7．What is the most important reason for the rapid development of the shared bikes
A．Lots of money.
B．Support from the government.
C．The shared bike itself.
D．Support from Mobike and Ofo.
8．How is the passage organized
C
What would life be like without enough clean, safe drinking water About two billion people around the world have to think about it because they face this problem every day. Many scientists are trying to help them. One of them is Emily Tianshi.
Emily grew up in southern California. As a child, she and her family would go hiking every weekend. On these hikes she would see a type of pine called the Torrey Pine. The girl became interested in these trees. What is special about them Well, the climate in southern California is dry all year round, but Torrey Pines are still able to grow very well. They can often even be found with big puddles(水坑) under them.
When she was 13 years old, Emily began to closely study Torrey Pines. She learned how the trees' thin, sharp leaves take in water from the air. Whenever they take in too much water, they pour out the extra amount to form the puddles on the ground. Emily made a device called Torrentis. The device looks like the thin sharp leaves of a Torrey Pine. Every night, the girl would leave it outside. She would go back early in the morning to see if it had “harvested” any water. Over the years, Emily has tried to make the device work better. Many scientists now think highly of it.
Together with her brother Kyle, Emily has also started the “Clearwater Innovation” project. She wants to help more people learn about the world's water problems. “Mother Nature is my teacher for many things，” the girl said. “You can learn something from her and do something for her.”

The ground shook suddenly. Houses moved, and people ran into the streets with scares. With people running around, Zhang Heng stood still, thinking quickly. “There must be a way to know when this will happen，” he thought. He had seen many earthquakes(地震) in his life, and each time, people couldn't do anything. But this time, Zhang Heng decided to find a method.
For days, he could think of nothing else but the earthquake. He was a man who loved science and understood the power of nature. After studying the stars, the sky, and the earth for years, Zhang Heng had an idea—what if there was a machine that could feel earthquakes before they happened
Without wasting any time, Zhang Heng began to work on his invention. He used bronze(青铜) to create a large container with eight dragon heads, each holding a small ball in its mouth. At the bottom of each dragon, he placed a frog. If an earthquake happened, the shaking would cause the ball to fall into the frog's mouth, showing the direction of the earthquake.
Months of hard work passed, and one night, Zhang Heng was ready to test his invention. Suddenly, the ground shook again. His heart raced as he rushed to the machine. To his surprise, one of the dragon heads dropped its ball! The ball fell into the frog's mouth, pointing west. Zhang Heng smiled with excitement. It worked!
A few days later, a strong earthquake hit the west, just as the seismoscope(地动仪) had shown. People were amazed, and Zhang Heng's invention saved many lives by giving them a warning before the disaster.
Though his name became famous, Zhang Heng never stopped searching for answers. He knew that science was a never-ending journey, and he was always ready for the next challenge.
13．What was Zhang Heng trying to do in the story
A．To build some machines to help people with everyday tasks.
B．To create a container to tell the weather ahead of time.
C．To become famous for his scientific work and inventions.
D．To find a way to warn about earthquakes ahead of time.
14．How did Zhang Heng's seismoscope work
A．The eight dragon heads could move slowly to show earthquakes.
B．The shaking from an earthquake made balls fall into the frogs' mouths.
C．It showed the temperature change before an earthquake happened.
D．The machine could tell exactly when an earthquake would happen.
15．What was the seismoscope's test like
A．The seismoscope did not work at all and failed.
B.The machine showed the earthquake's direction.
C．The frog opened its mouth and shouted loudly.
D.The invention was damaged during the test.
16．Which of the following best describes Zhang Heng

四、(2025鞍山模拟)阅读与表达(共4小题，41～43小题，每小题2分，44小题4分；满分10分)
阅读短文，然后根据内容回答问题。
After a game like football, the players might get an X-ray in the hospital if they hurt their legs or arms. A dentist can use X-rays to look at teeth. And airport workers use an X-ray machine to check objects before a plane leaves. Nowadays, X-ray technology is widely used in medicine and other fields.
X-rays were first discovered by a German scientist, Wilhelm Conrad Rntgen(1845-1923). He found them quite by accident in 1895. One day, he discovered that an unknown kind of radiation(放射线) could hardly pass through hard objects like bones(骨头). Later, Rntgen took a photo of his wife's hand. It clearly showed her ring and her bones. That was the first X-ray photo in the world.
Why is there an“X” in the word “X-ray”？ It's because Rntgen couldn't explain exactly how it worked. He just knew that X-rays were new and useful for science. In fact, X-rays soon became an important tool in medicine. With the help of X-rays, doctors could see inside the human body for the first time without surgery(外科手术).
Rntgen was awarded the first Nobel Prize in physics in 1901 for his discovery. When he was asked what he was thinking at the moment of discovery, he replied, “I didn't think. I investigated(调查).” Rntgen gave away his Nobel Prize money to his university. And he never applied for any patents(专利权) on X-rays to make sure that the world could freely make use of his discovery.
41．Where is X-ray technology used
________________________________________________________________________
42．When were X-rays discovered
________________________________________________________________________
