When the bell rings, every student takes out an iPad. The light from the screens(屏幕) makes their young faces pretty and lively. That’s what happens every day at my school in the US. We use iPad in class.

I feel surprised and excited when I get an iPad the first day I get to the school. But it is not free. I spend about $100 renting(租) it for three years.

Every iPad at my school has a special learning system(系统) called Focus. Teachers put their teaching material like textbooks and PPTs on it. When we have classes, we enter the system and download(下载) the materials with our iPads.

It makes the classes interesting and efficient(高效). For example, a few weeks ago, we learned about London in the UK. Our teacher prepared a video. Through the video, we saw many places of interest in London. We could not only watch the video, but also see the words at the same time. Because of the video, I know more about the city.

We also do our homework with iPads. We can know how well we do our homework right after we submit (提交) our homework.

However, there are still some bad points about learning with iPads. Some of my classmates play games or surf the Internet in class.

I believe the key to use iPads well is to have good self-control (自制), isn’t it?

Robots make our lives(生活) easy and convenient. Robots often(经常) help us in our lives. Here are two new and fun robots. They have special skills. What can they do? Let’s find out together.

Look at this fish-like robot. It can swim just like a real fish. With its cameras and LED lights, it can find its way underwater(水下) now. In the future(未来), scientists hope to use it to find missing people in the sea.

Here comes the world’s first robotic kitchen. Look, the robot has two long arms. It can cook you dinner. It can take food out of the fridge and stir (搅拌) food in a pot. It also can clean the kitchen and even wash the dishes. What a great helper!

Have you ever watched a space lesson on TV? On December 9, 2021, a special science lesson was given to millions of students in the China Space Station (CSS). The teachers are Zhai Zhigang, Wang Yaping and Ye Guangfu.

On Wednesday, March 23, 2022, three astronauts at the CSS gave their second space lesson to the students on Earth. The astronauts did some amazing experiments in microgravity(微重力). They were experiments that demonstrated the crystallization process, surface tension, separating water and oil, and momenturm in space. The astronauts also used popular Winter Olympics 2022 mascot figurine Bing Dwen Dwen to demonstrate (证明) how an object would move in a weightless environment.

For the lesson, there were three classrooms in Beijing, the Tibet Autonomous Region and the Xinjiang Uygur Autonomous Region where the students could communicate with astronauts in real time. Millions of primary and middle school students across China watched the space lesson, which made them take pride in the rapid development of our country’s space technology.

Shi Yi, a physics teacher at the Beijing No. 101 Middle School, said, “The space lesson is an eye-opening experience that can develop students’ interest in science.” Wang Yihan, a fifth-grade student at the Yuxin School in Beijing, said, “The astronauts’ experiments have really made me surprised. I am really interested in spaceflights (太空飞行). I want to be an astronaut in the future.”

“We will carry out more science experiments in the future and bring more scientists to the station,” Chinese astronauts Wang Yaping said.
