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（证明）that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant（香的）flavor（作料）was added to the vitamin-enriched water, the rats did seem to prefer 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（自助） 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 choosing 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-formed 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．

A．encourage rats to drink vitamins-enriched water

B．test whether rats know which drink is good for them

C．find out rats’ preference in flavor

Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist’s nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight cavities.
55．What is the main purpose of this passage?
A. To discuss how cavities can be treated.
B. To point out the problems with Halloween celebrations.
C. To tell parents what sweets are less damaging to their children’s teeth.
D. To teach parents the meaning of Halloween candies for their children.
56．Why are hard candies especially bad for teeth?
A. They may break the child’s teeth.
B. They contain too much sugar.
C. They help bacteria to produce tannins.
D. They stay in the mouth for a long time.
57．According to the passage, which of the following is a better choice for Halloween treats?
A. Chocolate. B. Crackers. C. raisins. D. Potato chips.
58．According to the passage, which of the following is true of tannins?
A. They are produced when the bacteria digest the food.
B. They help to get rid of some bacteria in the mouth.
C. They help chocolate to dissolve more quickly.
D. They destroy the surface of the teeth.

Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter (粪) from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers (化肥) are also very useful. The same crop (庄稼) should not be grown in the same place every year; it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
