单选题{{B}}Passage 3{{/B}} {{U}}The agriculture revolution in the nineteenth century involved two things: the invention of labor-saving machinery and the development of scientific agriculture. {{/U}}Labor-saving machinery naturally appeared first where labor was scarce. "In Europe", said Thomas Jefferson, "the object is to make the most of their land, labor being sufficient; {{U}}here{{/U}} it is to make the most of our labor, land being abundant." It was in America, therefore, that the great advances in nineteenth-century agricultural machinery first came. At the opening of the century, with the exception of a crude (粗糙的) plow, farmers could have carried practically all of the existing agricultural tools on their backs. (80) {{U}}By 1860, most of the machinery in use today had been designed in an early form. {{/U}}The most important of the early inventions was the iron plow. As early as 1890 Charles Newbolt of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would have none of it, claiming that the iron poisoned the soil and made the weeds grow. Nevertheless, many people devoted their attention to the plow, until in 1896, James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.

单选题About a month ago I was present at a serious occasion of the reading of a will. I can remember one passage that particularly struck me. It ran something 【B1】 this. "And I direct that $10,000 be 【B2】 to old William B, whom I have wished to help for many years, 【B3】 always put off doing so." It 【B4】 the last words of a dying man.

单选题The world is known to us through many senses, not just hearing, smell, vision, and at close range, touch and taste. Our skins let us know whether the air is moist or dry, whether surfaces are wet without being sticky or slippery. From the uniformity of slight pressure, we can be aware how deeply a finger is thrust into water at body temperature, even if the finger is enclosed in a rubber glove that keeps the skin completely dry. Many other animals with highly sensitive skins, appear to be ahle to learn still more about their environment. Often they do so without employing any of the five senses. By observing the capabilities of other members of the animal kingdom, we come to realize that a human being has far more possibilities than are utilized. We neglect ever so many of our senses in concentrating on the five major ones. At the same time, a comparison between animals and man draws attention to the limitations of each sense. The part of the spectrum (光谱) seen by color- conscious man as red is non-existent for honey-bees. But a bee can see far more in flowers than we, because the ultra-violet (紫外线) to which our eyes are blind is a stimulating part of the insect"s spectrum, and for honey-bees at least, constitutes a separate one.

单选题{{B}}Passage 11{{/B}} Obviously television has both advantages and disadvantages. In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don't have to pay for expensive seats at the theatre, the cinema, or the opera. All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort on his part. Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one's sitting room. (11) {{U}}It could be argued that the radio performs this service as well; but on television everything is much more living, much more real.{{/U}} Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it, so dependent on its pictures that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begun to talk to each other again. It makes one think, doesn't it? There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society.
