The biggest hamburger restaurant chain(连锁) in the world is McDonald’s. It started in 1955 with just one restaurant, but now has more than 20000 worldwide. There are more than 12000 McDonald’s restaurants only in the US. You can find them in 100 countries on six continents. There isn’t a McDonald’s in Antarctica, but I don’t suppose they eat hamburgers at the South Pole. When you eat at a McDonald’s restaurant you are joining the 35 million people who eat and drink at McDonald’s every day, and there are more than one million people who work there. McDonald’s has sold 100 billion hamburgers since it opened, and it sells more than 6.8 million pounds of French Fries every day.

How do you like your hamburger restaurant? There are old McDonald’s ---- part of one restaurant in England is 600 years old. There are elegant(高雅的) McDonald’s ---- there is one on the Champs Elysees in Paris. There are cool McDonald’s ---- there is one in Hollywood. There are McDonald’s restaurants on ships and trains, in hospitals and zoos, in airports and in colleges.
