invention AI is!

, we can search information we need in a few seconds with the help of AI looking up too many books for a long time.

He said AI in our daily lives now.

Last Friday, Dr. Smith gave us a speech AI.

Jane Goodall (1934-2025) is a world-famous e on chimpanzees. She showed great interest in animals from an early age.   A she was young, she bravely went to Africa to study wild chimps in 1960. She would quietly watch and record their daily activities for many hours. She n that chimps can make and use tools just like humans. This was a big b in the research of chimps. Jane faced so many c while watching chimps, but always had a positive mind. She made great contributions to the study of humans and animals. She is exactly the role model we need to learn from.

Technology has greatly improved the performance of modern athletes. They use modern equipment (装备) to help them run faster, jump higher and win more.

These shoes are made of special materials to reduce weight and provide better support. High-tech is helping bicyclists, too. They ride bikes made from lightweight materials like carbon fiber. These bikes are built to reduce wind resistance and help them ride faster and more smoothly.

What's the future of smart sports equipment? It uses sensors (传感器) to tell athletes what is going on in their bodies. These sensors are also able to tell how much energy they are using. One product in development is a wearable sensor. It tells runners when and how much they need to drink.

Coaches use computers, apps, and smart tools to help their athletes learn better skills. For example, some coaches use video analysis tools to study and improve their athletes' movements. Virtual reality (VR) has also become part of the training. It allows athletes to feel like they are competing in real matches, helping them prepare for possible challenges.

With technology, athletes can improve their performance and achieve amazing results. The mix of hard work, talent, and smart tools helps athletes reach their best level.

A. A recent development is smart clothing.

B. Runners wear high-tech shoes to go faster.

C. Modern technology also improves training.

D. A small change in design can make a huge difference.

E. However, technology will never take the place of talent or hard work.

As for the number 3, people in Sweden think all good things come in threes. They think three is the first option for them to get new numbers or room numbers. But people in Japan don't think so. They don't like taking photos when there are only 3 people. They think something bad will happen to the one in the middle.

In China, people think the number 6 means everything goes well. During the Spring Festival, many parents give 666 yuan to their children as lucky money. But the number 6 is not popular in most English-speaking countries. It has something to do with bad luck. So it's not wise to use it when you talk with your friends from the UK or the USA.

The number 9 also has a good meaning. It sounds like Chinese Pinyin "jiǔ", meaning a long time. In Norway, 9 is a lucky number, too. There are many nice stories about it. But people in Japan don't like it. When they say it in Japanese, it's just like the word "ku" and it means something painful.

Some people think the sounds of numbers have nothing to do with their meanings. And lucky numbers are just for fun. In my eyes, if some numbers make you feel lucky, just use them as you like. But don't forget to work hard at the same time. I think it's the hard work that can always bring people good luck, not only the numbers themselves.

Kate Sessions was interested in trees when she was a child. While other girls didn't want to get their hands dirty, little Kate enjoyed picking up branches (树枝) and fruits in the forest. Kate also danced and sang songs happily there. She felt the trees were her friends. She loved the way they grew toward the sky and how their branches stretched (延伸) to get the light. Kate thought the trees were like big umbrellas that protected her and the animals, birds and plants that lived in the forest. Kate smiled as she walked among the trees, enjoying the sounds of birds. Not everyone felt at home in the forest, but Kate did.

Kate learned well in school. She learned how to read and write. She remembered the stories she read. But best of all, she liked studying wind and rain, plants and trees, especially trees. At that time, very few girls chose to study science, but Kate chose to learn ecology (生态学) because of her love for it. She still tried to make her dream come true as a person who knew much about trees.

After leaving school, Kate came to San Diego, a city with few green plants and bad air. Kate made a decision to better the air of the city, so she brought different kinds of trees to San Diego and called on her friends to plant trees with her. With hard work, they made Balboa Park in San Diego a beautiful and fantastic garden. Kate is also known as the "Mother of Balboa Park".

When I entered middle school, Mr. Jackson taught us science. On the first day of class, he gave us a talk about an animal called "wampus". He told us that the wampus lived on the earth millions of years ago during the Ice Age and died out because of the change of climate. We all listened carefully and took1 of everything he said. Later we had a2.

When the exam paper was3 to me, I was surprised and sad. There was a big red "×" through each of my answers. I failed. But how come? Anyway, on the test paper, I had written down what Mr. Jackson said in class.

Then I realized that no one4 the exam at all. What had happened?

"Very simple," Mr. Jackson explained. "I had5 all that story about the wampus. There had never been any such animal, so the information in your notes was not correct. Do you expect to get high marks for incorrect answers?"

There was no need to say we were6. What kind of test was this? What kind of teacher was he?

How could we believe he gave us so much information about an animal that had not been there at all? How was it possible for us students to7 what the teacher taught us?

"The zeros on your papers will be8 in your grade books," he said. And he did it.

Through this experience, Mr. Jackson hoped that we would learn something. Teachers and books are not always9. In fact, no one is. He told us not to let our mind go to sleep. Instead, we should keep thinking all the time and speak up if we think there are mistakes in our teachers' words or in books.

We should develop the habit of doubting and the ability to decide by ourselves. What a special10 he gave us!

I swam to a rock. I climbed onto it and1 my head to face the rising sun.2 a fire in me that burned for the deep blue. It was the only place where I felt truly free.

I jumped back and3 went deeper, with my eyes open. Among a group of fish and4 sea animals, I noticed a big shell. I took it and swam to the surface. I put it on the rock and swam back in. This time I went even deeper,5 I wasn't afraid. It was beautiful.

And then I saw something moving towards me. It was a shark! I had never seen such a big one in the wild. I was caught by fear. All I'd learned6 sharks rushed into my head. I knew I7 slowly back away, but I swam8 to it. And when it was about five feet away, I got to know it was simply a Caribbean reef shark. They aren't dangerous, so I decided9 it quietly. Then it slowly swam away.

Now, more than ever, I understand10 I love the sea—it is full of unknown danger, yet beautiful.
