Unit6. When was it invented?

课文范文

This special pen was invented by Liu Jie. It has three colors and is used for taking notes quickly. It is very useful if you have a lot to write down. The pen comes with a microchip that can store a list of common words that you will use. You can program the words you will use often into the microchip’s memory, then assign a short from to each word. When you are writing, you just need to write the short forms with the pen, press a button, on the pen and all the short forms will change into the actual words. The microchip can contain up to 50 words and you can make changes to the list of words whenever you need to.

I want to invent a special chair

Hello, everyone! As we all know, many great inventions have brought great convenience to our life. I think we students can also invent something.

Today I’m glad to be here to talk about what I’d like to invent----a special chair that is good for students’ health. It will be made of wood. There will be two sensors in it—one on the seat, and the other straight, the chair will remind him. If he sits on the hair for over one hour, it will make a noise. It won’t be extremely helpful and useful for our health.

That’s all. Thank you!

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 TV and the bicycle. TV provides with different kinds of information so that we can know more about the world. We watch entertainment programs to relax ourselves. Besides, some learning programs help us with our study.

The bicycle is very useful, too. We go to school or work by bike. It’s not so expensive that most of us can afford it. It makes no pollution, which is good for our environment. What’s more, bicycle riding is a kind of exciting sports which is quite good for our health.

Though there have been many great inventions, I wish to invent a kind of pen which can help us write more quickly and neatly. When we eat problems in doing our homework or taking exams, it will tell us how to solve them.

That’s all. Thank you very much.

How Tea Was Invented

Tea is one of the most popular drinks in the world. Do you want to know how tea was invented?

It is said that tea was invented by Shen Nong. One day, Shen Nong was boiling water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time. Shen Nong noticed that the water gave out a pleasant smell. He decided to taste the water and he found it is delicious.

In this way, tea was invented. So we can say that tea was invented by accident.
