　　 Last Sunday I went to see my aunt with my brother. My aunt made some beef sandwiches for us. They were very delicious. After lunch, I asked my aunt to teach me how to make a beef sandwich.

　　 First, she put a teaspoon of butter on a slice of bread. After that, she cut up an onion and a tomato. She added them to the bread. Then she put some lettuce and four slices of beef on the bread. Next she put two teaspoons of relish on the beef. Finally, she put another slice of bread on the top.
