As is known to us all, the hamburger is a popular American food. So many people think the Amen-cans made hamburgers first. However, people in the U.S. learned to make it from the Germans and the Germans got the idea from the Russians. Thousands of years ago, people from Asia moved into Russia and the place around it. They fought the Russians and won. They ate something like hamburger meat, but it was raw( 生的 ). This raw meat was beef, goat meat and horse meat. Soon the Russians started to eat raw meat, too. Then Germans learn - ed to eat this food from the Russians. But they ate other things, such as eggs, and then cooked it. Many years later, some Germans moved to the United States and they brought in ham burgers. People called it hamburger steak (牛排) .Later , people ate it with their hands , like sandwich .This was the first hamburger we eat today.
