To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against the rain. Its first use was as a shade 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 eleventh century B.C.

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. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office.

In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common used in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.

During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered as a symbol of power. By 1680, the umbrella appeared in France, and later on in England.

By the eighteenth century, the umbrella was used against rain throughout most of Europe. 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 women’s umbrellas began to be made, in a whole variety of colours.

45. According to this passage, the umbrella was probably first invented in ancient _______.

A. China         B. Egypt       C. Greece         D. Rome

46. Which of the following statements is not true about the umbrella?

reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.3

3. Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.5  Or go dancing with your friends.

A.Focus on the future.

B.This can be especially harmful to the aged.
