范文欣赏： An adjustable dustpan
This is my new invention—an adjustable dustpan. I think it can be widely used in our daily life. I came up with the idea because of my mother.My mother is tall， so she always feels tired when she bends down to use the normal dustpan. After doing some study, I invented this adjustable dustpan for her. It looks like a normal one but it has a special handle. It can be adjusted longer or shorter according to the users' need. Without doubt, I think it is my best invention.I hope a large number of adjustable dustpans will be produced to help more people.
