Shopping used to mean going to shops, but nowadays, you can shop without even leaving your house. Just sit in front of your computer, click (点击) your mouse and your things will be sent to your house in several days. You can also use your mobile phone to buy things you want.

November 11 is a big day for many people who like shopping online. On that day, many shops offer a big sale. The biggest Chinese online shopping sites are Taobao. com and Tmall. com.

Goods (商品) online are often much cheaper. Shopping online also saves you a lot of time. And you often have more kinds of goods online than in shopping centres. Another big advantage of online shopping is that it helps you get things easily from different cities, even different countries.

While enjoying online shopping, many people also have worries, especially for middle school student buyers. They often buy things that they don't need. "Middle school students should pay more attention to their study. Searching for things to buy online wastes their time," said teachers.

    Good morning, everyone!

    Today, I'm going to talk about inventions.

    Inventions are created every day because people would like to make life easier.

There are famous inventions like

    Is it difficult for you to get up in the morning? Hiroyuki's bed will solve your problem!

    The bed is connected to an alarm clock. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music. The tape recorder in Hiroyuki's bed plays a recording of his girlfriend. She whispers in a sweet voice, "Wake up, darling, please." A few minutes later, Hiroyuki hears a recording of his boss. His boss shouts, "Wake up at once, or you'll be late!"

    If you don't get up after the second recording, a mechanical "foot" in the bed will kick you in the head. The bed waits a few minutes. What? You're still in bed! The foot of the bed goes lower and lower. Finally you slide off the bed and onto the floor. You are out of the bed and awake!

    There is only one bed 一 the bed Hiroyuki made for a contest. Maybe someday a company will make Hiroyuki's bed and sell it. Maybe people will buy millions of beds. Then Hiroyuki will be rich. If the bed makes Hiroyuki rich, he won't need to work and he won't get up early.

    Cai Lun was the first recorded inventor of paper. He did much for the spread of papermaking technology in China. In 105 AD, he presented paper to the emperor. It was a big success and his paper began to be used all over China.

    Even after people in China began to use paper, it took another thousand years before paper was used all over Eurasia (欧亚大陆), In 400 AD, people in India began to make paper,

    In 751 AD, there was a big fight in Samarkand, where the Chinese and the Arabs were fighting for control. The Arabs caught some Chinese men. Some of these Chinese men knew how to make paper, so they explained how to make paper to the Arabs as the price of their freedom.

    By 1271 AD, the Italians had learned to make good paper. They sold it all over Europe. In 1338, French monks began to make their own paper. After more than 70 years, people in Germany began to produce their own rag paper. At that time, people in China were using paper in many different ways. They used it for kites, and even for toilet paper!
