4 . The Thermo Fisher Scientific Junior Innovators Challenge is a science competition for U. S. middle-school students. It's run by Society for Science, which also publishes Science News Explores. The 30 finalists in this year's competition traveled to Washington, D. C. and also showed off their research projects.
Sharanya Chudgar, 14 years old, is one of the finalists in the competition and built a trash-collecting robot. The wheeled machine of the robot uses sensors to spot litter and a pan to pick it up. The robot's metal-detecting sensor helps it sort garbage from recyclables. And a light sensor can let the robot's solar panel angle itself toward the sun, collecting as much energy as possible.
Sharanya got the idea to build her trash collector by participating in litter cleanups. "When I signed up to volunteer at our local trash cleanup, I saw how much litter poliution there was and I knew that I had to fix this problem," Sharanya says. "People do have very limited time and resources, right? But robots don't. So it was then that my project idea formed in my head."
"Building the robot is my favorite part of this project," Sharanya says. "Ever since first grade, I've loved building Legos and building my robot felt just like building a Lego. But this project was a completely new experience since I hadn't ever had any experience in robotics before. Throughout the project, I had to use tons of power tools and I even had to cut pieces of metal to certain lengths. Whenever I needed to use a power tool, I had to turn to my dad who was always there to help out if necessary."
"It might seem difficult at times, but sticking to this and changing just one variable at a time gets you the best results," Sharanya says. This middle school scientist is solving global problems of litter pollution. For some, a science project might be an assignment or a fun hobby. But for Sharanya, doing research can also be a chance to help others and make the world a better place.

7 . When wildfire smoke from huge fires in Canada blanketed the US in the summer of 2023, emergency rooms saw an increase in admissions for lung problems, heart attacks and other health issues.
Burning fossil fuels has driven climate change, and now climate change is costing people their health and increasingly their lives, says a new report from the medical journal The Lancet. The eighth annual Lancet Countdown, an international analysis that tracks nearly 50 different health-focused issues affected by climate change, calls for an immediate wind-down of fossil fuel use.
Those with the least historical responsibility for causing climate change are feeling the worst effects. Pakistan—a country responsible for roughly 0.3% of all climate-change-causing carbon emissions, suffered huge floods in 2022 that displaced more than 30 million people and killed at least 1,700. However, wealthier countries cannot be spared. In the US, wildfire smoke this summer sent people to the emergency room from New York to Georgia. In Europe, a 2022 summer heat wave resulted in over 60,000 deaths.
About one fifth of all US residents work outdoors; the percentages are even higher in many other countries. When it gets too hot, it gets harder and harder to work. Last year, the report says, outdoor workers lost more than 140 hours each — or several weeks of pay — because of the intense heat.
The human and economic costs are forecast to grow with every tenth of a degree hotter the planet gets. Heat-related deaths, for example, could increase by nearly five times by the middle of the century, if without immediate reductions to carbon emissions.
“I have a young patient who presents with uncontrollable asthma. She lives right next to a highway and is breathing in harmful air from cars burning gas,” Renee Salas, a doctor at Harvard’s Chan School of Public Health says. “So the treatment she needs is electric vehicles, home weatherization and air purification. These are prescriptions I can’t write.”
1. What can be learned from paragraph 3?| A．The wildfire has burned large areas of forest. | B．Pakistan is largely responsible for climate change. |
| C．Climate change has caused a lot of human deaths. | D．People in wealthier countries have good health care. |
| A．American residents worked very hard last year. |
| B．There is nothing people can do about climate change. |
| C．The economy has also been affected by climate change. |
| D．Heat-related deaths will double by the middle of the century. |
| A．She advocates green lifestyle. | B．She prefers to drive an electric car to work. |
| C．Young people are more likely to get asthma. | D．Hospitals are short of medicines to treat asthma. |
| A．The advantage of living in the US. | B．The cause of climate change. |
| C．The stress of working outdoors. | D．The harm of climate change. |
8 . A heatwave has hit many countries in Europe, pushing temperatures over 40℃. A heatwave is a long period of unusually hot weather. The heat is expected to continue until the end of July.
The Italian Island of Sardinia reached 46℃ on 18 July. The Italy government has asked people to dress in linen(a thin, light material) and to stay indoors between 10 am and 6 pm. The government has asked people to drink plenty of water but avoid alcohol, fizzy drinks and coffee, which can make you feel thirstier. In Rome, the country’s capital, people aged over 70can go to swimming pools for free to help them keep cool.
Wildfires have broken out in many places. In Greece, which recorded 41℃ on 18 July, fires near the capital, Athens, have destroyed huge areas of forest and thousands of people have been moved to safety. Heatwaves can make fires worse because hot weather dries plants, which fuel the fires.
In the US, temperatures in Death Valley, California, hit 53℃ on 18 July, close to the hottest ever recorded on Earth. On 16 July, the US National Weather Service issued warnings in parts of the country, affecting more than 80 million people.
Despite the high temperatures in many European countries, the UK is not experiencing a heatwave. This is because a different weather pattern has brought rain and lower temperatures to the UK.
The heatwave in Europe is being caused by a weather pattern that has stopped the air from moving very much. That means the hot, dry weather has got stuck and temperatures have kept rising. Earth is also experiencing a natural climate pattern called El Nino(厄尔尼诺), which causes the water in the eastern Pacific Ocean to warm up more than usual. This can lead to hot weather around the world. Temperatures in some parts of Europe were expected to fall on 20 July.

9 . Where do you keep ice? In die freezer, of course. That’s what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers from around the world. They’ve decided to store ice in Antarctica because global warming is causing some of the glaciers in places like the Alps to melt.
Jerome Chappellaz of the French National Centre for Scientific Research is involved in creating an ice vault (地下室) there. He says: “We are probably the only scientific community whose sample (样本) is in danger of disappearing from the face of the planet. If you work on rocks or on tree rings, the raw material is still here and will be for many centuries.”
And why do scientists need to study ice from the Alps, for example? Ice formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles (气泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate. By examining ice, we know carbon dioxide in the atmosphere is higher now than in the last three million years. Researchers use this kind of data to build computer models and try to predict what might happen in the future.
The ice vault will be housed in a snow cave at the Concordia Research Station, which is operated by scientists from France and Italy. The ice samples will be sealed in bags and placed 10 meters below the surface. at a constant temperature of -50℃. This will put the scientists’ minds at rest. Losing the ice samples would be a disaster, and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.
