第2题

To us it seems so natural to put up an umbrella to keep the water off when it rains, but a

ctually the umbrella was not invented as protection against 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 Chinese were the first to use it 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 and authority. In the Far East in ancient times , the umbrella was allowed to be used only by the king or 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 use 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 a symbol of power and authority. By 1680, the umbrella appeared in France, and later on in England.

By the 18th century the umbrella was used against rain throughout most of Europe. Umbrella 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 were made, in a whole variety of colors.

According to this passage, the umbrella was probably first invented______.

A．in ancient China

B．in ancient Europe

C．in ancient Greece

D．in ancient Rome

第3题

In the year 2100, the world is going to have a population of about 8 billion. Most scienti

sts agree that the most severe problem is food supply. Who is going to feed all these people？ Where is the food going to come from？ Are we going to have enough food？ Are we going to produce more artificial foods？ One way of improving the situation is for people to eat less meat. Why？ Because it takes 4 kilos of grain protein(蛋白质)to produce half a kilo of meat protein. Clearly, there is not going to be sufficient meat protein for 8 billion people. Therefore, it will also be necessary to change eating habits because meat is the main part of many people s food today. A possible solution to this latter problem is the soybean(大豆). The soybean plant produces beans which have a very high fat and protein content. Scientists can now make these look and taste like real meat. They can also make many other artificial products such as soybean milk, for example, which has a taste of milk and can be used in cooking in very much the same ways as cow s milk. In fact, one woman in the United States fed her family only on soybeans for a year! She gave them soybean beef, soybean chicken, soybean milk, and sometimes just soybeans. Possibly, we are all going to eat soybeans in the future and finally give up meat completely from our tables.

What is the main subject of the passage？

A．A solution to man"s food problem.

B．A solution to the population problem.

C．Advantages of soybean.

D．How to develop good eating habits.
