写作练习Hello everyone,
Today I want to talk about the development of mobile phones. The first mobile phone was invented in 1973. At that time, it was very large and heavy.
Now, mobile phones have become smaller and lighter. They have many uses. We can not only talk to others, but also take photos, listen to music and surf the Internet with them.
I believe that future mobile phones will be more powerful. Maybe they will be able to help us do more difficult things. I'm looking forward to it.
Thank you.
