Both the British and Americans speak English. However, there are several differences between American English and British English. For example, the words they use in daily life are not the same. The British call the first floor of a building the ground floor. The floor above the ground floor is the first floor, which Americans call the second floor. Once you go to Britain and America, you may notice other differences. The British usually hide their feelings. They don't often start a talk with strangers. On the train the British often spend their time reading newspapers or books. But Americans are more active and easier to talk with.

1. 在中国必须靠右行驶，这跟英国正好相反；

2. 当你碰到认识的人打招呼问好即可，不必经常握手；

                                                                                         Enjoying Dinner with Friends in America

        Americans, like many people else where in the world, like to invite friends to their homes for an evening of food, drink and conversation. Formal dinners, in fine homes and hotels in the United States are much the same as formal dinners anywhere in the world. But as most people in the United States have no servants (佣人) , their dinner parties at home are mostly informal. Guests may sit down at a table, or, as many new small homes have no separate (单独的) dining room or very small dining space, guests can also serve themselves and eat in the living room, holding their plates on their knees.

        A more enjoyable form of entertainment is the picnic. Americans are great picnickers, and almost every family has a picnic basket. Summer invitations are often for a picnic at a park or in the open countryside. Unless hamburgers or hot dogs are cooked over a fire, picnic food is usually cold sandwiches, salads, potato chips, etc. Watermelon is a favourite dessert, followed very often by baseball for the young and active, and naps (打盹) for the weary (疲惫的； 困乏的).
