单选题{{B}}Passage 3{{/B}} Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid piled higher and higher and spread wider and wider. In this way, an island rose up in the sea. As time went on, hot sun and cool rains made the rock split and break to pieces. Sea waves dashed against the rock. In this way, soil and sand came into being. Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch. Insects couldn't stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.

单选题{{B}}Passage 7{{/B}} Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. (7) {{U}}It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles.{{/U}} When a fragrant flavor was added to the vitamin-enriched fluid, the rats did seem to develop a taste for it and kept drinking it, even after the vitamins were switched to the clear water. In time, however, they broke {{U}}the habit{{/U}} and went back to where the necessary vitamins were. In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet. So, in selecting food, rats and babies do seem to know and act on what's best for them. Apparently, there is a kind of "body wisdom," which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-established habits. Some people eat fox, dog and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them.
