英文名：Potato Chips
概述：薯条（Potato Chips）是
一种把马铃薯切成条状后油炸而
成的食品，是最常见的快餐食品
之一，流行于美国及欧洲等地。
美国人多称之为“French Fries”，其实它真正的来源地是比利时。
早在1680年的时候，比利时人就开始制作这种薯条了 。在第一次世界大战的时候，美国士兵在比利时吃到了这种薯条，觉得特别美味，从而变得流行起来。但他们想当然的称其为“French”，是因为当时在比利时军队中的通用语言是法语，他们就以为是“法国的薯条”了。

To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade (遮蔽) against the sun.21世纪教育网版权所有
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the 11th century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.
In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.21教育网
