求一篇关于美国文化的英语作文

As we know,America is a young country,however,its culture is quite splendid,which is admitted by people all over the world,especially its fastfood culture.
In 1948,the Richards opened up the first fastfood restaurant,named Mcdonald's,beside a highway.In order to attract people passing by,they lifted up the golden neon signs,mainly selling out the hamburgers,milkshake,soda water and so on which are packed with paper bags.Due to it's convenient to carry with,those people that on the car can find the solution to eating,therefore,it's very popular with the Americans.Based on the industrial pipeline,a new kind of the fastfood came into being.With its appearance,a new lifestyle started to spread to the whole America,even affected the whole world later on.
In my opinion,the reason why the American fastfood is so popular owes to people's fast rhythm of life,and Americans are always seeking for the high efficiency no matter in their work or life.
