单选题. The Chinese of 3500 years ago believed that the earth was a chariot, and the sky was a curved canopy stretched above it. The canopy was nine layers thick, and it sloped slightly to the northwest, as a cataclysm had broken one of its supporting columns. This gentle slope explained the movement of the stars from east to west. According to these ancient Chinese beliefs, the sun spent the night on earth and ascended to the sky each morning from the luminous valley of the earth by climbing the branches of an immensely tall sacred tree. To the Chinese people, the sun was the incarnation of goodness, beauty, and truth. In popular imagination, the sun was represented as a cock that little by little assumed human form. His battles with the dragons, which personified evil in their beliefs, accounted for momentary disappearances of the sun that men now call eclipses. Many of the Chinese people worshiped the sun, but in the vast and complicated organization of the Chinese gods, the sun was of only secondary importance. Along with these unsophisticated beliefs about the sun, the Chinese evolved a science of astronomy based upon observation—though essentially religious—which enabled them to predict eclipses of the sun and the movement of the stars. Such predictions were based on calculations made by using a gnomon—an object whose shadow could be used as a measure, as with a sundial or simple shadow pointers. Moreover, with the naked eye, the Chinese observed sunspots, a phenomenon not then known to their contemporaries.1. The ancient Chinese believed that the earth ______.

单选题. Since the late 1960s a growing number of women have expressed a strong dissatisfaction with any marriage arrangement wherein the husband and his career are the primary considerations in the marriage. By the end of the 1970s, for example, considerably less than half of the women in the United States still believed that they would put their husbands and children ahead of their own careers. More and more American women have come to believe that they should be equal partners rather than junior partners in their marriages. This stage of marriage, although not typical of most American marriage, at present, will grow most rapidly in the future. In an equal partnership marriage the wife pursues a full-time job or career which has equal importance to her husband's. The long-standing division of labor between husband and wife comes to an end. The husband is no longer the main provider of family income, and the wife no longer has the main responsibilities for household duties and raising children. Husband and wife share all these duties equally. Power over family decisions is also shared equally. The rapid change in women's attitudes toward marriage in the 1970s reflected rapid change in the larger society. The Women's Liberation movement appeared in the late 1960s, demanding an end to all forms of sexual discrimination against females. An Equal Rights amendment to the U. S. Constitution was proposed which would make any form of discrimination on the basis of sex illegal, and though it has failed to be ratified, it continues to have millions of supporters.1. During the late 1960s many women disliked the marriage ______.

单选题. The agriculture revolution in the nineteenth century involved two things: the invention of labor-saving machinery and the development of scientific agriculture. 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; here it is to make the most of our labor, land being abundant." It was in America, therefore, that the great advances in the 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. By 1860, most of the machinery in use today had been designed in an early form. 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 home 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 1869, James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.1. The word "here" in Line 4 refers to ______.

单选题. Computers may one day turn night into day—with good old, natural sunlight. Colossal computer-controlled mirrors, thousands of feet across, may one day orbit the earth, reflecting sunlight onto a darkened United States. Some scientists say that 16 of these mirrors, each about a half mile across could aim their reflected light at one area on the earth that was about 200 miles by 300 miles. That much light would equal about 56 moons. The mirrors would be so high that they could catch the sun's light as it was shining on the other side of the earth. The mirrors could orbit—thousands of miles high—at the same speed as the earth turns on its axis (轴). That way, the mirrors would always be over the same spot. The aluminum-coated (涂铝的), plastic mirrors could be folded up and packed into a space-ship, according to the scientists. Once released a few hundred miles in space, the mirrors, powered by a solar-powered engine, could make the rest of the trip into space on their own. The scientists say that the computer-controlled mirrors could also be made to tilt (倾斜) slowly, so the reflected sunlight would sweep slowly along the surface of the earth. For example, as night fell, the mirrors could be tilted to light up Boston. Later on, as darkness spread slowly west-ward, Chicago, for example, then San Francisco could be lit up. The reflected sunlight would allow these cities to save up electricity. And in emergencies, such as power-failures, the mirrors could light up the affected area. What no one knows yet is what effect this artificial daytime would have on plants, animals, and humans. Would it confuse some animals and harm plants that are used to regular day-night cycles? The scientists recommend that studies be done to find out what bad effects there might be.1. The word "colossal" in Para. 2 most likely means ______.
