rally look for unskilled, low-paying jobs. 54 ., if the minimum is high, employers may hire fewer workers. They will 55 workers with machinery. The price, which is the wage the employers must pay, increases. Therefore, other things being equal, the number of workers that employers want reduces and poor people may find themselves without jobs instead of with jobs at the minimum wage. Economic theory predicts the results of economic decisions like about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the Value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions. PART IV. English- Chinese Translation (15%) Directions: Read the following passages carefully. Then translate the following 5 sentences into Chinese. Computers may one day turn night into day---with good old, natural sunlight. （1）Colossal computer-controlled mirrors, thousands of feet across, may one day orbit the earth, reflecting sunlight onto a darkened United States. (2)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 spaceship, 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. (3)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 westward, Chicago, for example, then San Francisco could be lit up. The reflected sunlight would allow these cities to save up electricity. And in eme
