单选题(B) "Time cannot be added to a person"s life, but it can be made more valuable by avoiding waste. " This was the philosophy of a man who devoted most of his time to the creation of new plants: Luther Burbank, the plant magician. Burbank has been called the plant magician because he could do things with plants which were as amazing as the tricks of a magician. He truly astonished the world with his achievements in the development of many kinds of plants, such as giant fruits with new flavors and trees which grew faster than their ancestors. These, and many more achievements, were of great economic value and benefit to people all over the world. In his lifetime of seventy-seven years Burbank became an American legend. He began life in 1849 on a farm in the state of Massachusetts. It was the same year that men across the continent in California discovered gold, that precious metal so eagerly sought after in the earth. Eventually Burbank would follow them. But he would spend his life drawing a different treasure from the same California earth: a wealth of new plants and fruits. The Massachusetts countryside may have provided young Burbank with a feeling for the mysteries of nature, but his scientific training came during the visits of an uncle who was a scientist. Through his uncle, Luther met the famous naturalist, Louis Agassiz. Agassiz introduced him to the complicated process by which plants grow, such as the steps in the making of seeds from pollen (花粉) carried by insects, by birds, by the very winds of the field. Attracted by the ways of nature, Burbank took his first steps into the work that was to occupy his whole life.

单选题It is often difficult for a man to be quite sure what tax he ought to pay to the government because it depends on so many different things: whether the man is married; how many children he has; whether he supports any relations; how much he earns; how much interest he receives; how much he has spent on his house during the year, and so on and so forth. All this makes it difficult to decide exactly how much the tax is. There was a certain artist who was always very careful to pay the proper amount. One year, after posting his check as usual, he began to wonder if he had paid enough, and after a lot of work, with a pencil and paper, decided that he had not. He believed that he owed the government something. He was just writing another check to send to the tax-collector when the postman dropped a letter into the box at the front door. Opening it, the artist was surprised to find inside it a check for five pounds from the tax-collector. The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer.

单选题Many developing countries continue to export the traditional goods for which they have always been known, like tea from India and Sri Lanka, tin (锡) from Malaysia and Indonesia, bananas from Central America. The highly industrialized countries of western Europe, however, focus on selling manufactured goods (制成品): Electrical and engineering equipment, high-tech products like computers and jet planes, which are worth millions of pounds. But these patterns (格局) of trade are changing. Developing nations are creating their own manufacturing industries, and their products are often cheaper than those of Europe and North America. This is because of lower labor cost and the free availability (获得) of local materials, and they are not only cheaper, but often of higher quality when experience has been gained.
