单选题 The first true piece of sports equipment that man invented was the ball. In ancient Egypt, as everywhere, pitching stones was a favorite children's game. But a badly thrown rock could hurt a child. Looking for something less dangerous to throw, the Egyptians made what were probably the first balls. At first, balls were made of grass or leaves held together by vines. Later they were made of piece of animal skin sewed together and stuffed with feathers or hay. Even though the Egyptians were warlike, they found time for peaceful games. Before long they had developed a number of ball games, each with its own set of rules. Perhaps they played ball more for instruction than for fun. Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.

单选题 The humorous story may be told to great length, and may wander around as much as it pleases, and arrive nowhere in particular; but the comic (滑稽的) story and the witty (诙谐的) story must be brief and end with a point. The humorous story continues gently along, the other two burst. The humorous story is strictly a work of art--high and delicate (精美的) art--and only an artist can tell it; But no art is necessary in telling the comic and witty stories; anybody can do it. The art of telling a humorous story--I mean by word of mouth, not print--was created in America, and has remained at home. The humorous story is told seriously; the teller does his best to hide the fact that he him- self even suspects that there is anything funny about it; but the teller of the comic story tells you beforehand that it is one of the funniest things he has ever heard, then tells it with eager delight, and is the first person to laugh. When he gets through, and sometimes, if he has had good success, he is so glad and happy that he will repeat the point of it and glance around from face to face, collecting applause (喝彩), and then repeat it again.

单选题 To preserve food, the growth of bacteria (细菌) must be controlled. Water, warmth, and food are all needed for bacteria to become strong and healthy. Some kinds of bacteria need air, but other kinds grow only when air is absent. Extremes of temperature, either hot or cold, can kill bacteria. Before refrigerators were invented, freezing and cooling were limited by the cold climate. In warmer regions, food was cooled by putting it in the shade, in cold water from the well, or in pits (坑) in the ground. Cooking will usually kill bacteria if the temperature is high enough and the high temperature lasts long enough. Certain methods of cooking remove water, and this aids in preserving food. Drying is the oldest and most common method of preserving food. Food can be dried by the sun, by heat or by combination of the two. Salt was used by many hunting people. When people began to eat vegetables, salt became a needed part of their life. Salt helps to preserve food because it slows or stops bacteria to grow. Other chemicals besides salt are used in preserving food. Some people oppose the use of chemicals in food. They say that these chemicals may harm people if the chemicals can harm bacteria.

单选题 England is not a big country: from north to south and from east to west it is only about three hundred miles across. But for a small country it has a surprising range of climate. People who have never visited England or who have visited only one part of it often makes the mistake of thinking that it is a cold and wet country. Except for the summer months of June to September, this is probably true of the north of England and the Midlands. In the south, however, the climate is much more pleasant. One result is that when people retire from the job in the north, they often prefer to move down to the south. Perhaps the warmest part of the country is the southwest, which consists of (is made up of) the counties of Devon and Cornwall, where palm trees, bamboo and many semitropical plants grow well. Flowers and vegetables ripen as much as a month earlier than those elsewhere. Farmers in the areas gain a higher price for their vegetables and flowers because they are ready earlier. In winter there may be several feet of snow in other parts of England but there will probably be no snow at all in the southwest. This may be one of the reasons why the southwest is one of England’s most popular holiday areas.
