In many high schools, there are strict rules about using mobile phones. If your phone rings in class, for example, the teacher will be very angry.

    Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now, there is a ringtone called “mosquitotone (蚊子铃声)”.

    Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older, we are unable to hear some sounds with high frequencies (频率). As a result, a child or teenager can hear the mosquitotone ringtone, but someone of 20 or older can't.

    But sometimes, people over 20 can hear the ringtone. One British student's phone uses mosquitotone. In class, the student's phone rang. The 22-year-old teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class. ”

    Not all the students are interested in mosquitotone. Jerry Jones, a high school student of 17, says, “Using mosquitotone too often is bad for our hearing. I may use it for pleasure, but not in class. It's unfair(不公平的) to the teachers！”

    What do parents think of mosquitotone？“I think it is perfect for places like movie theaters,” says Connie Neeson, 44. “Think about it. You're watching a film and someone's mobile phone rings. Mosquitotone is good because many people don't hear it. However, it also has a bad influence（影响） on their study if students use it in class. ”

    Now too much CO makes the Earth warmer and warmer, and brings bad effect to people. To save our Earth, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.

    To live a low-carbon life, we'd better save as much energy as we can. For example, turn off the lights and TV when you don't use them, use cold water to wash clothes or dishes: take a short shower and try to take a cold one when the weather gets warm: don't do the cooking with electricity.

    To live a low-carbon life, we should eat less meat. Being a vegetarian can help reduce (v)one and a half ton of carbon dioxide a year, but keeping animals for food produces even more carbon dioxide than all the cars do in the world.

    To live a low-carbon life, we should plant more trees. Trees are very important for us. They can not only produce oxygen for us to breathe and keep the air clean. But also take in the harmful gases from the air. To protect trees we should stop people from cuing down trees and plant as many trees as we can.

    If we can keep them a habit in our daily life, the earth will become a safer planet for us to live on.

Breakout year for AI

For language masters like ChatGpt to helpful "painters" such as Midjourney, Al is changing how we live. No wonder(难怪) the UK's Collins Dictionary has named "A" as the Word of 2023.

AI is now an everyday technology, as common as e-mail or online video, said Alex Beecroft from Collins. And you can see this in "Time's Best Inventions of 2023". There are 14 Al tools on the list.

TrailGuard AI helps to protect wild animals. Small camera on it keep an eye on animals and look out for poachers(偷猎者). It has helped to catch 30 poachers in Africa.

How can we tell a real thing from a fake one? FeaturePrint helps. It is an app using AI. Take a photo of something like gold, a watch or a bag. Then FeaturePrint "sees" the details on it. It tells you whether the thing is real or not.

If these things can't make you excited enough, take a look at Google's most advanced (先进的)AI, Gemini. It can understand text, picture, audio (音频), video and code(代码). It does well in a test that includes 57 subjects, such as math, history and law.

What could Al do next? Will you use AI to help you with your study? We will have to wait and see.

If stars do farming work, can they do a good job? You can find the answer in the farming show Become a Farmer.{#blank#}1{#/blank#} Its first season (季) was very popular. Now, Season 2 of the show is airing.

It's important for us to keep healthy. Li Ming gives us a good example. Meals was the time when family members got together. But now fast food and quick meals are threatening(威胁) such family get-togethers. Facing such a situation (情况), Li Ming has a good idea. Though his parents often go to work at night, he also eats the healthiest food. He learns to cook himself.

He takes exercise in the morning. He likes sports such as swimming, running and playing basketball. He goes to bed at ten in the evening and gets up at six in the morning. He can take care of himself. He takes a bath every day and washes his hands before meals. When he has meals, he eats all kinds of healthy food such as fish, eggs, vegetables and meat. He also eats much fruits. So he looks strong. Do you want to be a person like him?
