Of all the inventions, my favorite is the Internet.
The Internet was invented in 1969s. It can be used to do many things. People can go online and search for information they need. They can send emails to each other instead of writing letters. People can also use the Internet to listen to music, play games, shop or do many other things. Nowadays, the Internet is widely used in banks, schools, companies, hospitals, and many other places. People can even see a doctor online at home, thanks to the Internet.
The Internet is so useful that it is becoming one of the most important parts of our life. It makes our lives more and more convenient. It also provides us with more job opportunities.

Failure Is the Mother of Success

The Greatest Invention in My Eyes
Hello, boys and girls!
Some people think that the greatest invention in the world is cars, while the others believe that computers are the most useful tools we need in the modern society. But in my eyes, the greatest invention is just books.
A famous person has ever said: “Books are the steps of human’s progress.” Exactly! That’s what I would like to say firstly. In the long history of human being, books have played an important part in providing us with knowledge. And it is knowledge that changes our lives.
Secondly, the best way to broaden our horizons is reading books, because books provide us with different ideas. As a result, we can have our own opinions different from others instead of obeying any other person’s.
What’s more, books are considered as teachers without sound. When we deal with difficulties, it is a good choice to ask for help from books. Books are like a patient teacher and will give us answers whenever we need.
So I think books are the greatest invention in the world because we can learn many useful things and get benefits from reading. Books make us a full man.
That’s all. Thank you!

Hello, everyone, I’m Li Hua. I have an invention dream. Now I’d like to tell you something about it.
I want to invent a special pen. It will be invented when I graduate from college. It will be made of steel. It is as heavy as a normal pen, but it’s a little longer. There will be three buttons on the pen. I think it is useful and convenient. First, it can be used as a pencil, a pen and an eraser. When you press the red button, it is used as a pencil. When you press the blue button, it is used as a pen. If you use the eraser, you can press the white button. Second, it will let you know if you’re sitting correctly by making a sound. It won’t stop making a sound until you sit correctly. It’s interesting, right
But it’s not easy to invent it. So first of all, as a middle school student, I must study hard to get more knowledge. I also need to be creative. I should always come up with new ideas. Most importantly, I should keep on and never give up. If I work hard, my dream will come true.

Dear Linda,
I'm very glad to introduce the new invention to you.

Although it mainly depends on solar power, it can still run very fast. Also, it can run not only on the land but also in the water safely. What's more, it can also use electricity to run when it's cloudy, rainy or snowy. Lots of people love this kind of car. I believe you'll also love it very much if you use it.

The Greatest Invention in My Eyes
Hello, boys and girls!
Some people think that the greatest invention in the world is cars, while the others believe that computers are the most useful tools we need in the modern society. But in my eyes, the greatest invention is just books.
A famous person has ever said: “Books are the steps of human’s progress.” Exactly! That’s what I would like to say firstly. In the long history of human being, books have played an important part in providing us with knowledge. And it is knowledge that changes our lives.
Secondly, the best way to broaden our horizons is reading books, because books provide us with different ideas. As a result, we can have our own opinions different from others instead of obeying any other person’s.
What’s more, books are considered as teachers without sound. When we deal with difficulties, it is a good choice to ask for help from books. Books are like a patient teacher and will give us answers whenever we need.
So I think books are the greatest invention in the world because we can learn many useful things and get benefits from reading. Books make us a full man.
That’s all. Thank you!

I hope my idea can be taken. Thanks!
【详解】题干解读：这篇作文要求学生们以An Important Invention为题给学校英语报社投稿，介绍一款你认为重要的发明，并简要描述一下这项发明以及你选择它的原因。这是一篇话题作文，题目中对文章的内容并没有给出太多的提示，学生们可结合自己的实际生活，从身边的高科技产品和服务入手，如智能手机、二维码、网购等等，介绍一下它们给我们的生活带来的改变。
写作指导：审题可知，这篇短文应以第三人称、一般现在时为主来叙述。写作时应首先亮明自己的观点，点明自己认为重要的发明是什么；然后阐述这个产品的作用和好处，即你选择这项发明的原因。注意英语句式结构的特点和表达习惯，不要按照汉语逐词翻译。可以简单句结构为基础，穿插并列句和复合句的使用，提升作文档次。同时注意上下文的衔接，使文意连贯、表达流畅。
20．One possible version
Hello, everyone, I’m Li Hua. I have an invention dream. Now I’d like to tell you something about it.
I want to invent a special pen. It will be invented when I graduate from college. It will be made of steel. It is as heavy as a normal pen, but it’s a little longer. There will be three buttons on the pen. I think it is useful and convenient. First, it can be used as a pencil, a pen and an eraser. When you press the red button, it is used as a pencil. When you press the blue button, it is used as a pen. If you use the eraser, you can press the white button. Second, it will let you know if you’re sitting correctly by making a sound. It won’t stop making a sound until you sit correctly. It’s interesting, right
But it’s not easy to invent it. So first of all, as a middle school student, I must study hard to get more knowledge. I also need to be creative. I should always come up with new ideas. Most importantly, I should keep on and never give up. If I work hard, my dream will come true.
What about your dreams Would you like to share them with me
