Today,roller skating (滑旱冰)is easy and fun. But many years ago, it wasn't easy at all. Before 1743, peoplenever tried skating on wheels. That changed because of a man named John JosephMerlin. Merlin's work was making instruments. In his free time he liked to playthe violin. Merlin was a man with many ideas and many dreams. People called hima dreamer.

    One dayMerlin received an invitation to go to an important party. He was very pleasedand a little excited. As the day of the party came near, Merlin began to think.He wanted to find a way to make a wonderful entrance at the party. Merlin hadan idea. He thought that he would attract a lot of attention if he could skateinto the room.

    Merlintried different ways to make himself roll. Finally, he decided to put twowheels under each shoe. These were the first roller skate shoes. Merlin wasvery proud of them. He dreamed of arriving at the party and skating into theroom while playing the violin. He was sure that everyone would be verysurprised.

    On thenight of the party Merlin rolled into the room, playing his violin. Everyonewas really surprised to see him. There was just one problem. Merlin had no wayto stop his roller skating. He rolled on, playing the violin. Then, with alleyes on him, Merlin hit into a huge mirror on the wall. The mirror broke intomany pieces with a very loud noise. But nobody forgot Merlin's wonderfulentrance after that.

Here is some cool information about the world's population（人口) . 

Have you ever heard of the company called Xiaomi in China? It was set up in 2010. They made smartphones and many other cool gadgets (电子装置) at the beginning. With the development of the times, Xiaomi decided to do something big and different. They created their very first electric car, called the SU7, and started selling it to people. The boss of Xiaomi, a man named Lei Jun, told everyone that the starting price of this new car would be 215,900 yuan (almost $30,000). It was a big event, and people were very excited. In just 27 minutes, more than 50,000 people ordered the new car.

Now, Xiaomi isn't the only company making electric cars. There are other big names like Tesla and BYD．Tesla is a car made in America, and it's known for being fast and modern. The price to start for a Tesla 3 is a bit higher, 245,900 yuan. But Xiaomi's car, the SU7, can go really, really far, at least 700 kilometers on one charge (充电)! That's more than the Tesla Model 3, which can only go 567 kilometers. At the same time, Xiaomi is thinking about how their customers use their phones and computers. They made the SU7's brain (operating system) work like the ones in Xiaomi's phones and laptops (手提电脑). This way, people can get everything connected and easy to use.

Xiaomi has big dreams for their electric car business, but no one knows yet whether they will succeed. Some analysts (分析师) think that Xiaomi's big idea will help make electric cars better and more exciting for everyone. So, what do you think? Will Xiaomi's SU7 develop faster than Tesla and become the king of electric cars? Only time will tell, but one thing is for sure: the world of electric cars just got a lot more interesting.

Too many Americans watch too much television. Americans maybe watch more TV than any other people in the world. This is not a good thing. Because of TV, Americans are getting too heavy and spend less time with their friends.

Many American students watch TV between twenty and sixty hours a week! That is very bad for their study. When they watch too much TV, they have less time for exercise, their study and sleep. Most people who watch a lot of TV eat food at the same time. This is very bad because they eat too much and become too heavy.

It is better to watch just a little bit of TV a day. Thirty minutes to one hour is enough. If you have much free time, it is a good idea to read a book, play sports or spend time with your friends and families. Studying is also a good way to spend your free time.
