When it is raining, we need umbrellas to get off the rain and we shouldn't hide under the tree. When it is sunny, we need sunglasses to protect(保护) our eyes and we have more fun time to play. When a storm is coming, we should stay inside and wait the storm ending. When it is snowy,we can see white show on the ground. How happy! We can make snowmen after snowing!
