Dear Kevin,
I'm glad that you' re interested in my invention. Let me introduce it to you.
My invention is a smart waste basket made of a special material. It was invented three months ago. It looks the same as common waste baskets, but there are four different areas inside it. It will open when people's hands get close to it. So it's really convenient. More importantly, it can not only be used for collecting rubbish but it can also be used to sort rubbish into different kinds automatically. This helps people save time and makes people's lives more convenient. It's a useful invention, right
Are there any special inventions in America I’m willing to know about them.
Yours,
Li Hua
