You may think that inventions are far away from your everyday lives. But in fact,almost everyone can invent something. It’s just that they do not realise that their ideas could be the start of an invention. When inventors see their ideas have some practical value,they don’t let them slip away（溜走）.
For example,the inventor of the dishwasher（洗碗机）,American Josephine Cochrane,loved to give dinner parties. But she found it took too long to wash the dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So,in 1886,she set out to make one for herself.
There are steps to create inventions. The first and most important step is to find the problem. Then you might notice situations or things in need of improvement. The next step is to work it out. An invention is a new way of solving a problem. So think of unusual ways. You can often come up with a solution to a problem by looking at it from a different side.
And the hardest part of inventing is to find a solution. When you have an idea,you can always get help to build your invention. This problem solving skill is very useful. It can also work in your everyday life. So,why not try it in your study,or even in the way you look at the world
