Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habits, because much of the food they eat, particularly foods, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming to- day.
Natural foods, for example, vegetables, fruits and grains which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for ex- ample, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar, this is actually a non-essential food! Although a natural alternative, such as honey, can be used to sweeten food if this is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be an additive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form. of calories. There are no vitamins in it, no minerals and no fibre.
It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetable. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetable, certain diseases are comparatively rare. Hence the emphasis placed on the eating of wholemeal bread and more vegetables by modern experts on healthy eating.
Recently, some people are interested in natural foods because ______.
A．these foods are fresh and sweet
B．they want to change their eating habits
C．these foods do not contain chemical additives and have not been affected by chemical fertilizers
D．they don't like the processed foods

In computing, passwords are commonly used to limit access to official users. Yet the widespread use of passwords has serious drawbacks. Office workers now have to remember an average of twelve system passwords. In theory they should use different passwords for each site, but in reality these would be impossible to remember, so many people use the same password for all.
An additional problem is that the majority use simple words such as "hello", or names of family members, instead of more secure combinations of numbers and letters, such as 6ANV76Y. This permits computer hackers to download dictionaries and quickly find the word that allows them access.
When system users forget their passwords there is extra expense in supplying new ones, while if people are forced to change passwords frequently they often write them down, making systems even less secure. Therefore, it is clear that the idea of passwords, which have been used as security devices for thousands of years, may need rethinking.
One possible alternative has been developed by the American firm Real User, and is called "passfaces". In order to access the system a worker has to select a series of photographs of faces from a randomly (随机地) generated sequence. If the pictures are selected in the correct order, access is granted. This concept depends on the human ability to recognize and remember a huge number of different faces, and the advantage is that such a sequence cannot be told to anyone or written down, so is more secure. It is claimed that the picture sequence, which used photographs of university students, is easier to remember than passwords, and it has now been adopted for the United States Senate.
What is the disadvantage of passwords as mentioned in Paragraph 1？
A．They do not ensure security.
B．They are difficult to remember.
C．They have to be changed frequently.
D．They limit computer accessibility.

Man depends on water for many things. He needs it for drinking. He needs it for growing food. He needs it for keeping himself clean and free from illness. He needs more and more water for industry. People often forget how necessary water is for industry. Imagine, for example, the immense quantities of water used by the great cooling towers of steel works. The demand for water is growing every day. It is closely connected with the increasing population and with the pressing problem of providing enough food. But the world has not yet found ways of storing enough water to satisfy all these important needs, not even in west countries like England. Great efforts are being made today to store water, particularly in hot countries where the rainfall is small.
Three-quarters of the world is covered with water. But only three percent of this water is fresh. All the rest is salt, and fills the oceans and the great inland seas. It is the salt that makes sea water useless to man. If you take the salt away the water can be used for drinking and for watering plants.
In 1962 President John Kennedy of the United States said, "When man discovers how to mm salt water into fresh water cheaply, he will have made a much more important scientific advance than when he first landed on the moon".

A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for "rank", especially socially. (76) Most Americans do not want to be treated in any especially respectful way because of their age or social rank; it makes them feel uncomfortable. Many Americans even find the terms "Mr. ", "Mrs." or "Miss." too formal. People of all ages may prefer to be called by their first names. "Don't call me Mrs. Smith, just call me Sally." Using only first names usually indicates friendliness and acceptance. However, if you do not feel comfortable using only first names, it is quite acceptable to be more formal. Just smile and say that after a while you will use first names but you are accustomed to being more formal when you first meet someone.
Very often, introductions are made using both first and last names: "Mary Smith, this is John Jones." In this situation you are free to decide whether to call the lady "Mary" or "Miss Smith". Sometimes both of you will begin a conversation using last names, and after a while one or both of you may begin using first names instead. You have a choice: if you don't want to use first names so quickly, no one will think it impolite if you continue according to your own custom.
In the first paragraph the author tells us that ______.
A．Americans do not talk about rank, especially socially
B．Americans feel uncomfortable when talking about rank
C．Americans take interests in social customs
D．Americans don't care much about social rank

A few years ago it was common to speak of a generation gap between young people and their elders.Parents said that children did not respect and listen to them, while children said that their parents did not understand them at all.What had gone wrong？ Why had the generation gap suddenly appeared？ Actually, the generation gap has been around for a long time.Many people argue that it is built into every part of our society.
One important cause of the generation gap is the opportunity that young people have to choose their own ways of life.In a more traditional society, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and like, and often to continue the family jobs.In our society, young people often travel great distances for their education, move out of the family at an early age, marry or live with people whom their parents have never met, and choose jobs different from those of their parents.
In our society, parents often expect their children to do better than they did, to find better jobs, to make more money and to do all the things that they were unable to do.Often, that is another cause of the gap between them.Often, they discover that they have very little in common with each other.
Finally, the speed at which changes take place in our society is the third cause of the gap between the generations.In a traditional culture, senior people are valued for their knowledge, but in our society the knowledge of a lifetime may become out of date.The young and the old seem to live in two very different worlds, separated by different skills and abilities.No doubt, the generation gap will continue in American life for some time to come.
