夏天,烈日炎炎,太阳把大地烤得直“冒烟”。看着路上撑着伞的行人都热得大汗淋漓,我就想:如果我发明一种空调伞给人们解暑,那该多好呀!我发明的这种伞伞柄上有四个按钮,第一个按钮是变换伞的颜色的,颜色越深防紫外线的功能越强,人们可以根据紫外线的强度调节伞的颜色。第二个按钮是变换形状的,可以变成方形、圆形、多边形、心形、椭圆形、星形……最神奇的要数第三个按钮 Summer, the hot sun, the sun grilled the ground straight “smoke ”. Looking at the pedestrian umbrellas on the road are sweaty, I thought: If I invented an air-conditioned umbrella to people hot weather, it would be nice! I invented this umbrella umbrella handle has four buttons , The first button is to change the color of the umbrella, the stronger the UV protection function, the more people can adjust the color of the umbrella according to the UV intensity. The second button is the transformation of the shape, can become a square, circle, polygon, heart-shaped, oval, star ... ... the most amazing number of the third button
