A

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 to water without vitamins, even though there is no difference in taste or smell between the two water bottles. When a fragrant (芳香的)flavor was added to the vitamins enriched fluid(液体),the rats did seem to develop a taste for it and kept drinking it , even after the vitamins were changed 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(自助餐厅) feeding arrangement, with a wide choice 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 choose a well-balanced diet.

So in choosing food rats and babied do seem to know and act on what’s best for them. Obviously, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as determined and influenced by long established(建立的) habits. Some people eat foxes, dogs 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 around them.

You can love them or hate them, but no matter which tourist destination you visit, chances are you’ll see someone with their head buried in a Lonely Planet guidebook.

   Lonely Planet is one of the world’s largest travel guide brands, publishing more than 500 different guides in eight languages.The popular brand also produces television shows, websites and podcasts(播客)all devoted to travel.

   Some people praise Lonely Planet books because they make traveling easy and affordable.They also save time and make sure you don’t miss the best things.

   They also provide the reviews of hostels(旅店), hotels, restaurants and ticket information about your destination.

   This can be great if you’re a nervous traveler, or if you haven’t traveled by yourself before.If you’re in a country where you don’t speak the language, sometimes there’s nothing better than getting into a taxi and opening up a guidebook.You simply point to a map that directs the taxi driver to a hostel that’s cheap and clean, with friendly staff and cold beer.

   But others criticize Lonely Planet and other travel guide publishers like them.They say guidebooks take the fun and spontaneity(自发性)out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen.They also regret that if you follow a guidebook, you’ll end up doing the same thing and having the same experience as everyone else.You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.

   Another criticism of travel guides is that they have a large impact on local communities.For example, some locals devote their lives to behaving in ways that attract tourists.They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.
