People praise the towering mountains and the rushing sea; Perhaps many people have praised love affairs, birds, animals, insects and fish. But few people praise the unpretentious stairs we step on every day. But today I want to praise the stairs and thank them for bringing me the convenience of going up and down the stairs. I want to praise the simple appearance of the stairs. Stairs are mostly cement or wood, and often have no gorgeous appearance. I have been to some high-rise buildings and many private houses. Their exterior and interior decorations are gorgeous, but the stairs are generally simple. Take my new house as an example. The outside looks beautiful, and every house is luxuriously decorated, but the stairs are ordinary and often dirty. I think the stairs are ordinary in appearance, but beautiful in heart. I want to praise the noble character of the stairs. The stairs are trampled by us every day. Many things go up and down the stairs, but the stairs are always unknown and serve us hard. Whether it is diligent in cleaning and whether it is often used; Whether you are noble or poor, whether you are rich or poor, it will serve you equally and send you where you want to go. Isn't the lofty moral character and broad mind of the stairs an example for us to learn? Stair, I want to praise you, I want to love you!
