Its first use was as a shade (遮光物)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, way back in the 11 century BC.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And therewas a strange thing connected with its use: it became asymbol of honour and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those inhigh office.In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrellawas in common use in ancient Greece. But it is believed that thefirst 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 16th 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.

To manypeople, the cause is clear: we eat too much. But scientific experiments do little to support this idea. Going back to the America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines muchless, and didn't watch television.Several modern studies, besides, have shown that fatter people donot eat more on average than thinner people. In fact, some research work, such as the 1979 study of 3,545 London office workers, reports that fat people eat less than thinner people on average. Studies show that thin people are more active than fat people.A study by the research group at Standford University School of Medicine found the following fact: the more the man ran, the greater body fat he lost.The more he ran, the greater was his need for food. Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.11.What kind of physical problem do many grown-up Americans have?答案:They are too fat.12.Based on the information given in this article, suppose there are 500 grown-up Americans,about how many of them have a weight problem?答案:15013.Are there scientific facts to support that eating too much is the cause of the" weightproblem"?答案:There are hardly any scientific facts to support this./doc/828910399.html,pared with the grown-up Americans today, The Americans of1910_______.答案:ate more food and had more physical activities15.What have some modern medical and scientific researchers reported to us?答案:Fat people eat less food and are less active.第三部分:词汇与结构(共5小题;每小题3分，满分15分)16.The client may win in court, but at the_______of destroying the business relationship, hesays.答案:expense17.When I got home, the house was a complete _______.答案:mess18.We usually eat lunch at home, why don't we make a _______ to eat at the restaurant.答案:change19._______ you turn in your homework, you'd better check your answer carefully答案:Before20.When I take a train home, I usually read novels to _______the time.第四部分:完形填空(共10小题;每小题1分，满分10分)Most children with healthy appetites are ready to eat almost anything that is offered to them.
