    Clothing is a language. It tells us about individual people: their personality, age, place in society and so on. If we want to know more about society, we can look at traditional clothing.

    The continent of Africa has a long history and a rich culture, and this is shown in traditional dress. You often find three colors— red, gold and green in the clothing. The first color stands for the blood of millions of people who suffered as slaves(奴隶), the second is for the rich resources of the African earth, and the third represents the grasslands of home.

    The patterns on the clothing also have a meaning. A common pattern is in the form of a cross “×”, which stands for “unity”. Another pattern is a rectangular（矩形） box, which represents “strength”.

    Because clothing has a strong social meaning, people are very careful in choosing what to wear. It would be a serious mistake to wear the wrong clothing, or to wear clothes in the wrong way. For instance, in Ghana, a woman should wear her waistband differently according to the importance of the social event. 

    Traditional dress also tells us about everyday life. African designs are famous for loose(宽松的) clothing. The climate, with the hot sun and wide temperature ranges(变化), requires that the clothes are comfortable for daily life. 

    Although many people wear western clothes, particularly in the big cities in Africa, traditional dress is very highly valued(评价). This is because it has deep cultural meanings.

    In England, traffic keeps on the left. Cars, buses and bikes all move on the left side of the road. But the traffic keeps on the right in China. So when you are in England, you must be very careful in the street. Before you cross a street you must stop and look both ways. Look right and look left and look right again. If the traffic lights are red, the traffic must stop. Then the people on foot can cross the road. If the traffic lights are green, the traffic can go. People on foot mustn't cross.

    In the morning and in the evening, when people go to or come back from work, the streets are very busy. Traffic is very dangerous (危险的).

    When you go by bus in England, you have to be careful, too. Always remember(记住)the traffic moves on the left. If you don't have a look first, you will go the wrong way.

    In many English cities, there are big buses with two floors. You can sit on the second floor. From there you can see the city very well. It's very interesting.
