The Most Useful Invention
①The mobile phone is without doubt one of the most useful inventions. It was invented by an American called Martin Cooper in 1973.
②I should say that the mobile phone has really changed our lives. First, it's more convenient to communicate with others by using the mobile phone. Second, people are used to taking photos with a mobile phone instead of a camera. And we can even go shopping, listen to music and watch movies on it. Third, we can easily learn something useful by surfing online. In this way, it helps us study.
In my opinion, we teenagers should be allowed to use the mobile phone, but not on weekdays.③And it's necessary to use it in the right way with the help of our teachers and parents.

Unit 6 范文
As we all know, there are a lot of inventions in history. Some of them play an important role in people’s life and some have brought great changes to our life. And we students can also invent something.
Today I’m glad to talk about what I invented. Many of my classmates have poor eyesight, so I invented a chair that’s not only comfortable to sit on but also good for
students’ health. It is made of environmentally friendly materials. What makes it special is that when the student doesn’t sit straight, the chair will remind him.
The most important thing I learned from this experience is to be brave and never give up. Keep thinking and talking about your ideas with others, and you will discover something amazing.
