專升本英語閱讀理解模擬試題及答案(8.29)

　　閱讀理解：

　　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】D 根據(jù)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，當(dāng)富含維生素的水中加入香味時，即使將維生素轉(zhuǎn)換為清水，老鼠似乎開始喜歡并一直飲用它。再根據(jù)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，隨著時間的推移，它們打破了喝加入香味的水的這種習(xí)慣，重新飲用含有必需的維生素的水。由此可推知，the habit指的是“喝加入香味的水”。故選D。
