A Useful Invention in My Life
Many inventions make our lives better.
答案
One possible version:
A Useful Invention in My Life
Many inventions make our lives better. Mobile phones are without doubt one of the most useful inventions. They were invented by an American called Martin Cooper in 1973.
Mobile phones have greatly changed our lives. First, we can keep in touch with others at any time and everywhere with the help of a mobile phone. Second, we can also use it as a camera to take photos and share photos online. Finally, mobile phones have made it easier for people to surf online. For example, we can watch movies, listen to music, play games, go shopping or even have online lessons as long as we turn on the mobile phones.
Although mobile phones have so many advantages, I hold the opinion that we teenagers should avoid playing games all the time. It's important for us to use mobile phones in the right way.
