Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

Clothing is a language. It tells us about individual people: their personality, their age, their 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 colours — red, gold and green in the clothing. The first colour 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(图案) 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 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.
