英语作文我的小发明.请尽量写的简单点 词量在60

Recently I have made a small invention,which is a tool for both sitting and preventing rain.Yes，the thing I invent has an appearence of umbrella but it can also be treated as a small chair or stoll（凳子）.if you are going on a vacation in summer,you can take it with you to prevent the sun .Of course you can use it to prenvent rain as well. If you feel tired after a long walk,you can unfold it ina right way,then you can sit on it to have a good rest. Believe me,It is absolutely a good tool for traveling.
