专升本英语阅读理解模拟试题及答案(8.29)

　　阅读理解：

　　Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. 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. 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 the habit 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. At first they showed some unusual eating patterns, but 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 foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seem to be greatly influenced by what is going on around them.

　　【精析】C 根据第一段最后两句“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 the habit and went back to where the necessary vitamins were.”可推知，在针对老鼠的实验中，将带有芳香的味道加入老鼠喝的水中是为了测试老鼠是否知道哪种水对它们有好处。故选C。

　　2.The expression “the habit” in Paragraph 1 refers to drinking water which ______.

　　【参考答案】D[考点]词语理解题

　　【精析】D 根据上文中的“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.”可知，当富含维生素的水中加入香味时，即使将维生素转换为清水，老鼠似乎开始喜欢并一直饮用它。再根据第一段最后一句“In time, however, they broke the habit and went back to where the necessary vitamins were.”可知，随着时间的推移，它们打破了喝加入香味的水的这种习惯，重新饮用含有必需的维生素的水。由此可推知，the habit指的是“喝加入香味的水”。故选D。
