先通读下面的短文,然后根据短文内容,在文章后表格的空格内填入一个最恰当的单词。所填单词必须写在答题卡对应题号的横线上。每个空格只能填一个单词。

    Clothing(服装) is a language. We can look at the traditional clothing to know more about culure.

    Africa has a long history and a rich culture, and this is shown in traditional dress. The three colours—red, gold and green, are often used in the clothing. The first colour represents the blood of millions of people who fought for freedom; the second, rich resources of the African earth; and the third, the grassland of home.

    Because clothing has strong social meanings, people are very careful in choosing what to wear. It would be a serious mistake to wear the wrong clothes, or to dress in the wrong way. For example, in Ghana, a woman should wear her waistband (腰带) 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 temperature there can be very high during the daytime but very low at night, so it requires that the clothes are comfortable for daily life.

    Today although more and more young people like wearing Western clothes, especially in big cities in Africa, traditional African dress is still quite valuable. This is because it has deep cultural meanings.
