When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wild, everyone has his own way to protect himself. Even plants have their own ways to fight against their enemies.
Over millions of years, plants have developed their own way to protect themselves. Chemicals (化学物质) are used by plants to live. By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree's leaves, and the number of poisonous chemicals becomes more in the other leaves. "It's like the injured (受伤的) leaves telling the others to fight against the enemy together," he said.
The tree also sends messages to plants near it by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison in 10 minutes. Now, if an enemy eats too many of the trees' leaves, he will die.
Every kind of plant is good at producing special chemicals. Animals that feed on plants or grass, like rabbits, can safely eat the leaves of one tree, but they may be hurt by its neighbor.
In this way, plants have not only developed their own way to protect themselves, but also shared it with others. So it's impossible for a single animal to damage even a small area of forest.
Teachers in the sky On Dec. 9, three Chinese astronauts (宇航员) give a science lesson 400 kilometers above the earth! They show students their life there. During the lesson, Zhai shows their clothes—"penguin suit". Sometimes they wear them to keep strong. Wang also shows another way to keep healthy-they exercise with bikes every day! ____ When you see: it for the first time, you may think it's the famous painting Girl With a Pearl Earring《带珍珠耳环的少女》. But it's not, it's just a picture made by designer Julian using artificial intelligence (AI). The AI-made artwork shows up at a museum (博物馆) in March. ChatGPT causes storm A survey shows that over 89%students in US use ChatGPT OpenAI (a smart AD) to help with homework, so some American schools stop the use of ChatGPT. However, not all the schools say "no" to ChatGPT. Some Canadian universities are making rules on its use, for students and teachers. |
John is a student who keeps the phone with him all the time. His dad thinks he is addicted (上瘾的) to the phone, but John doesn't think so. They write to each other.
Dear John, It's reported that fifty percent of the teenagers depend on their phones too much. I think you have this problem too. That's why I think you should give up your phone. Not forever, just for a week. I'm warned that you are developing some bad habits. Yon keep your phone with you all the time—you even check the basketball scores at the dinner table. It's not a good idea to use your phone while you are doing homework Because you can't put your heart into your homework at all. And you may make more mistakes when you can't fully put your heart into it. Love Dad |
Dear dad, I know you think I depend on my phone too much. But my phone helps to make my life better in many ways. Do you remember that time when the car broke down? I sent a message to tell you that I was going to be late. If I didn't, you would be worried about me for hours. My phone helps me with my homework too. I can look up anything in a second. It's really hard to be successful today if you don't have a phone. Social media, games, and apps might seem silly to you, but they help me to keep in touch with my friends. I promise to cut back my phone use, and I won't use it at the dinner table any more. But giving it up for a week wouldn't change anything in the long term. Love John |
