The umbrella was invented in China 1000 years ago(有ago就不用加over了).It is said that it was invented by Lu Ban's wife .Lu Ban often always worked outdoors,so sometimes he was drenched by rain（sometimes放前面读着更顺） .His wife saw him work so hard,then she wanted to create（produce更倾向于生产）a thing that could block (是想说挡雨吧)rain.And in this way,the first umbrella was invented .Today,umbrella is used to prevebt the water.
