     One day an American called Simon went to London to visit his friend, Rick. Rick told him that his flat

was on the first floor. When he arrived, Simon went straight to the first floor of the building. But he was

told that there was no Rick on that floor. Do you know why?

     In fact, the British call the first floor of a building the ground floor. The floor above the ground floor is

the first floor, which Americans would call the second floor.

     The story shows that there are a few culture differences between Britain and American, though the

British and Americans both speak English.

     The British usually hide their feelings. They seldom start a conversation with strangers. For example, on

the train the British often spend their time reading newspapers or books. But Americans are quite different.

They're more active and easier to talk with.

     The British and Americans may use different terms for many things. The British usually use football,

eraser and mail while Americans prefer to soccer, rubber and post.
