    A rabbit is running into its hole. You may ask, "What happened?"

    Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is a danger. The rabbit has told them something without making a sound. It has given them a signal.

    Many other animals use this kind of language too. When a bee found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the other bees to go with it to find food.

    Some animals say things by making sounds. A dog barks, for example, when a stranger comes near. A cat purrs (发出呼噜呼噜的声音) when it is pleased. Some birds make several different sounds, each with its own meaning.

    But human beings have something that no animals have—a large number of words about things, actions, feelings or ideas. We are able to give each other information and to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animal can do this. No animal has the wonderful power of language.

    No one knows how man learned to make words. As centuries went by, he made more and more new words. This is what we mean by language.

    People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example, contains four or five hundred thousand words. But we do not know all of them. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we meet a new word, look it up in the dictionary. A dictionary is the most useful book.

We live in the “computer age”. Today, it is more and more i{#blank#}1{#/blank#}for us to use computers. We use them at w{#blank#}2{#/blank#}, and we also use them at home. Adults use computers and c{#blank#}3{#/blank#}use computers, too. We often use the mouse to run all the work.

Slowly, you may f{#blank#}4{#/blank#}painful and numb(麻木的)in your hand, your wrist, your shoulder, and your neck. What's w{#blank#}5{#/blank#}with you? The mouse is eating your body f{#blank#}6{#/blank#}your hand to all. Some researchers explain that we feel painful b{#blank#}7{#/blank#}we often repeat the same action—click(点击). So we feel u{#blank#}8{#/blank#}little by little.

Nowadays, there are no best ways to s{#blank#}9{#/blank#}this problem. The only way is to change the way we use the mouse and the keyboard(键盘). When at work, we should have a break and e{#blank#}10{#/blank#}to keep our body healthy.

"Our teas can help protect your teeth and your heart, possibly even helping to prevent cancer," said Luo Shengkai, one of four student hosts from Sichuan University High School. They 1 introduced three self-made health teas through a livestream (直播) on Douyin 2 March 27, 2022, and they 3 for several weeks by now. The livestream got over 60 4 likes and many online orders, with all profits (收入) going to local tea farmers.

"It's 5 first time we have sold tea online. We not only need to introduce 6 tea, but we also need to interact with the audience and answer their questions," said Luo. "We've learned a lot from the process, 7 it's tiring."

Luo is one of a group of students 8 take part in a two-year course on tea research. They learn about tea planting and picking, tea making, package design and marketing through research and fieldwork.

However, 9 a new and popular tea isn't easy. Luo and his team members 10 a tea to better protect students' eyesight. They first met with a professional from Chengdu University of Traditional Chinese Medicine and researched the properties (特性) of local tea. Then they learned 11 functions of ingredients such as goji berries (枸杞), mangosteen (山竹果) and cassia seed (决明子) and did experiments to find what would happen if they 12 all together. They ended up with a cassia seed tea and then added 13 ingredients based on people's feedback.

"Through the tea course, students 14 learn how to be creative and improve their hands-on skills. They also learn to respect tea workers and how to contribute to rural vitalization (乡村振兴). That's 15 our educational means." said Mi Yunlin, the principal of the school.
