【題目】閱讀下列短文,從每小題所給的A、B、C、D四個選項中選出一個最佳選項。

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.
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.
