阅读理解Have you ever made something to solve a problem?
Have you ever made something to solve a problem?If you have,you’re an inventor.Inventors often make things to solve problems.These things are called inventions.Some inventions are new things while other inventions make old things better.About half a million kids invent things each year and some kids even sell their inventions.A six-year-old girl didn’t like cleaning the spoon she used to feed her cats,so she invented a spoon that cats can eat!A young inventor from Houston made a ramp(活动坡梯) for wheelchair users,which can be carried in a bay on a wheelchair.Sometimes one inventor makes more than one thing.For example,one young girl invented a bell that rings when a baby opens a drawer.This girl also made a new handle(把手) for cleaners.Some families have more than one inventor.One girl invented the Kiddie Stool.It is a stool which is fixed to a door and can be carried in the bag when it is the Happy Hands.She filled gloves(手套) with sand which could be used to put on the top of some papers to stop them from moving.How do inventors come up with new ideas?They listen to people complain about problems and that is how they find things that need to be improved.Look around,listen to people,and you might find a problem you can solve,too!
