1 . How to improve your home’s energy efficiency
Ensuring that your home is energy-efficient possibly keeps your bills right down and helps you play your part in the fight against climate change.
Insulate (使隔热) your loft
Most of your home’s wasted energy will attempt to escape through your roof. To stop it in its tracks, you must invest in having your loft insulated.
By investing in a top-of-the-line boiler, you’ll no doubt tap into an extra of savings. What’s more, making this kind of investment will also be sure to lower your home’s carbon emissions. When choosing a new boiler, give precedence (优先) to those that fall in or near the “A” category. Whatever you do, just don’t slip towards the lower end of the scale.

7 . The next generation of scientists and inventors is already finding approaches to address society’s problems. A group of high school students and their instructor report a solution to the problem of lead (铅) pollution in drinking water — an inexpensive faucet (水龙头) attachment that removes this poisonous metal. Unlike conventional filters currently on the market, theirs includes a container made of eco-friendly plastic and indicates when it’s “used up” by turning the tap water yellow.
“A few years ago, I saw a video of a woman in Michigan turn on her tap water, and it came out brown.” says Rebecca Bushway, the project’s principal investigator. “That made me think — because there’s really no safe level of lead in drinking water, wouldn’t it be nice to have a water filter that could tell you your water is polluted, well before it turns brown because of lead?”
Bushway, as a science teacher, wondered aloud to her chemistry class if there was a little filter that they could make from inexpensive components to easily remove lead. The students were excited about the idea, and they started thinking about the project in 2020.
The students discussed designs for an attachment to screw (用螺丝固定) a filter onto a sink’s faucet. Then in the spring semester of 2021, they 3D printed the attachment and a 3-inch-tall filter housing, using eco-friendly plastic. They filled the containers with some chemical powder. Next, the students added a tiny spectrophotometer (分光光度计) with a single-wavelength LED to the bottom of the filter container. They installed an indicator light that turns on as soon as the detector identifies the yellow color of the lead iodide (碘化铅).
The team’s goal is to make and sell their filters for less than $1 each. Because the housings use eco-friendly plastic, the cost could trend a little higher, but the material would help reduce the overall environmental impact of the filter.
The process of developing the filter has been very fulfilling. “Ultimately, this experience has shown students they can make a difference to somebody, and that there are problems they can fix with science,” said Bushway.

9 . A Hollywood-quality movie may soon be only a few text prompts away. OpenAI last week revealed its latest, world-shocking technology: a text-to-video app called Sora that can produce photorealistic short videos lasting up to a minute.
The company hasn’t released Sora to the public yet, but the artificially generated videos it created for its demonstration were stunning. In one, the detailed prompt involves people walking through Tokyo while cherry blossoms are flying through the wind. The resulting video was a mind-blowing exercise in world-building, showing a couple walking in a detailed streetscape that is unmistakably Tokyo. Perhaps even more awe-inspiring is that Sora does not merely produce videos that fulfill the demands of the prompts. It improvises (即兴创作) in a way that suggests a talent for storytelling.
“Good grief,” said Loz Blain in New Atlas. “We’d better try to deal with the speed at which this technology is advancing. The wheel, the steam engine, the airplane, the computer, the Internet... None of them ever sped up like this. If you look closely, you can’t tell that these very short videos aren’t real. But it’s impossible to say whether this technology is nearly as good as it’s going to get. Videos made a year ago, using the AI tool Midjourney, couldn’t even display the correct number of fingers on a hand. But Sora now creates a world as you describe. Get ready for the next wave of ‘AI disruption (颠覆)’ as Sora shakes the entertainment industry.”
Yet costs are increasing, too. Estimates of the cost of building out AI systems have varied from hundreds of billions to 7 trillion dollars over the coming years. Where’s the money going to come from? With OpenAI’s current valuation approaching $100 billion, traditional investors are largely priced out. Governments may be one possible solution, but many are likely to have national security concerns about backing this technology.
Such concerns are well founded. It’s simply impossible to know how these systems will be misused until they’re out in the wild. While OpenAI has the ability to prevent violent pictures, disinformation is much harder to police. Faked videos could so w confusion and chaos. At the very least, OpenAI should wait until after November to bring Sora to the public.

In Texas, a concerned father named Bradley learned that his 17-year-old son, Brad, was causing trouble at school. It wasn’t just a one-time occurrence; Brad’s physics teacher had complained multiple times about his constant talking during class. As a result, Bradley was faced with the challenge of finding an effective way to discipline his son and teach him a valuable lesson.
In a moment of inspiration, Bradley came up with an idea that parents around the world would later praise him for. He decided to teach his son a lesson. He declared, “If we receive another call from your physics teacher, I will go to your school and sit beside you in class.”
However, Brad didn’t take his father’s words seriously and continued his loose conduct in his physics class. And his father received another call from the teacher, and now it was time for the father to keep his promise.
Friday arrived, and Bradley, who normally had this day off from work, was awakened by his wife. He reluctantly got ready to go to his son’s school. Upon arriving at the school, he made his way to Brad’s physics classroom. The other students chatted joyfully, unaware of what was about to happen. Bra d entered the room as usual, and to his shock, he saw his father sitting by his desk. It hit him like a ton of bricks. His dad had actually come to school and was sitting right next to him in class. The once happy-go-lucky teenager was now filled with embarrassment and regret.
Throughout the class, Bradley silently observed his son’s behavior. He witnessed first-hand the disruptive comments and constant talking that had been causing so much trouble. It was clear that Brad was not taking his education seriously, and his father realized that something needed to be changed.
注意: 1.续写词数应为150个左右;2.请按如下格式在答题卡的相应位置作答。
After the class ended, Bradley apologized to the physics teacher for his son’s behavior.
