单选题John: I' d like to share with you what' s in my mind. Cathy: ______

单选题There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do. (76) In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. (77) What is remarkable about the history of toys is not se much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsman ship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arctic(北极的) peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent(进步).The progress from a rattle(拨浪鼓) used by a baby in 3,000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.

单选题We all know that it is possible for ordinary people to make their homes on the equator (赤道), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)-we know that it is not only a dangerously cold place, but that people like you and me would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger planes do not make), but the weather, if we are flying at a height of 5, 000 meters above the Pole, is a delight. At 4, 000 meters and more above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach. In the tropics (热带), on the other hand, you are not certain to keep clear of bad weather even at such heights as 18,000 or 20,000 meters. Planes can't climb as high or as quickly in cold air as in warm air. Nor can clouds. (18) In practice, this is an advantage to the plane, which is already at a good height when it reaches the polar region and so does not need to climb, while at the same time cold air keeps the clouds down low.

单选题The United States 1 a large part of the North American continent. Its neighbors are Canada 2 . the north, and Mexico to the south. 3 the United States is a big country, it"s not the largest in the world. In 1964 its population was over 185,000,000. When this land first became a nation, after winning independence from England, it had thirteen states, 4 of the states was represented on the American flag by a star. All the states were in the eastern part of the continent. As the nation grew towards the west, new states were in the eastern part of the continent. As the nation grew towards the west, new states were added and new stars 5 on the flag. For a long time, there were 48 states. In 1959, however, two more stars were added to the flag 6 the new states of Alaska and Hawaii. Sometimes 7 is said that the Indians are the only real Americans. Most Americans, however, are descendants(后代) of people who came from all over the world to find a new 8 in a new land. 9 who came first and in greatest numbers to make their home on the eastern coast of North America were mostly from England. It is for that reason that the language of the United States is English and that its culture and customs are more like 10 of England than of any other country in the world.
