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．
In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .

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

D．demonstrate the vitamins are tasteless

B．both have the wisdom to choose a balanced diet

C．both have the same eating patterns

D．both develop a taste for the same kinds of flavors

China has input several billion yuan of money to stop the dirty water waste on the upper and middle area of the Pearl River from polluting the lower reaches of the river, especially the Macao Special Administrative Region．
The Guangxi Zhuang Autonomous Region in the upper and middle reaches of the Pearl River has been rapidly urbanized（城市化）and industrialized in recent years, leading to a rise in the amount of urban rubbish to the damage of the land, rivers and atmosphere．
Refuse dumps and special plants in most cities treat rubbish to make it harmless, with 5,800 tons of wastes being burnt, buried or made into fertilizers on a daily basis．
He Suping, a woman engineer with the water resources department in Guangxi said, it is imperative for the autonomous region to treat sewage wastes to protect the area’s Karst terrain（喀斯特地形）and rain water which brings contact between groundwater and surface water, making groundwater more easily polluted．
The Xijiang River, a branch of the Pearl River which runs from Guangxi to neighboring Guangdong Province, provides fresh water for a number of riverside cities such as Macao, Zhuhai, Zhongshan and Zhaoqing, so Guangxi must begin to treat rubbish quickly to protect the water sources, said Liu Chen, a senior engineer with the Ministry of Water Resources．
The government 2001—2006 plan to spend billions of yuan to turn wastes harmless has been mainly provided by national debt payments and overseas investment．So far wastes treatment projects have received a total of 400 million yuan（48 million US dollars）from national debts and 60 million yuan（7．22 million US dollars）from overseas loans（贷款）．

A story from the Bible tells of old Babylon, where the men decided to build a tower that would touch the sky．But God was unhappy, and he made them speak different languages．They couldn’t understand each other, so their dream never came true．
Yet the dream remains alive: if all men speak the same language, they can do anything．L．L．Zamenhof from Poland was among the men who pursue this dream．He developed Esperanto（世界语）between 1877 and 1885．
As the most successful man-made world language, it is spoken by over two million people around the world．Last month, the World Esperanto Congress（大会）, dealing with language rights, ended in Sweden．The 2004 conference will be held in Beijing．Most Esperanto speakers are in Central and Eastern Europe and in East Asia, particularly Chinese mainland．
Esperanto has two advantages．First, it’s easy．Each letter has exactly one sound and there are just 16 basic grammar rules．The second advantage is that it belongs to no one country．But Esperanto has only reached a small number of people compared with natural languages widely used around the world-such as English or Chinese．While these languages are deeply connected with their nations and cultures, Esperanto doesn’t have this background．
Will Esperanto really become a global language? It remains a question．

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”．Personally, I could do without the phone entirely, which makes me unusual, because the telephone is changing our lives more than any other piece of technology．
Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic．My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day．If the phone did not exist, would she have anything to talk about?
Point 2 The mobile phone means that we are never alone．“The mobile saved my life,” says Crystal Johnstone．She had an accident in her Volvo on the A45 between Otley and Skipton．Trapped inside, she managed to make the call that brought the ambulance（救护车）to her rescue．
Point 3 The mobile removes our secret．It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are, where they are going, and how their last meeting went．
Point 4 The telephone separates us．Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window．It was easy to get his number．We were so near—but we didn’t meet for the first two weeks!”
Point 5 The telephone allows us to reach out beyond our own lives．Today we can talk to several complete strangers simultaneously（同时地）on chat lines（at least my daughter does．I wouldn’t know what to talk about）．We can talk across the world．We can even talk to astronauts（if you know any）while they’re space-walking．And, with the phone line hooked up to the computer, we can access the Internet, the biggest library on Earth．
How do you understand ‘Point 1 —The telephone creates the need to communicate,…’？

A．People don’t communicate without telephone．

B．People communicate because of the creating of the telephone．

C．People communicate more since telephone has been created．

D．People communicate more because of more traffic．

A．c, d

B．a, e

C．a, c

According to a report by the China News Weekly, Chinese white collars are becoming fully occupied in the office．They pursue many of their activities in the office building, eating, doing exercise, resting, playing games or even dating．
In large cities such as Shenzhen, Shanghai and Beijing, where economy is developing at a fast speed, office workers face an increasing work pressure day by day and many of them have begun to make office their home．
As the young generation in society, most of them are aged between 25 and 45．In the eyes of outsiders, they enjoy a comfortable life: they lead the fashion trend in the city and earn a high salary; they enjoy a flexible working schedule and a very good working environment; having a good education background, they don’t have to worry that one day they will lose their jobs．
However, only the white collars themselves know what others see as a good life is in fact a boring life．They often work for extra hours, suffer from loss of creative ability and have little time to make friends．When they go off from work late at night, sometimes they might think of asking for a leave the next day and having a holiday somewhere．However, when a new day begins, they find everything back to normal and themselves pushed by new tasks．
In fact, even if they don’t work for extra hours in the office, they have no place to go．Many of the young people are fresh from college, or have come to work in large cities from their hometowns．As newcomers, they haven’t established（建立）a social network．They have few friends to go dating．Meanwhile, many of them face a great pressure for earning money to buy a house or a car．If they cannot afford to buy these, they still have to work to pay for high apartment rents and communication fares．
