=Around 120 years ago, Ebbinghaus began his study of memory. He concentrated on studying how quickly the human mind can remember information. One result of his research is known as the total time hypothesis, which simply mean the amount you learn depends on the time you spend trying to learn it. This can be taken as our first rule of learning. Although it is usually true that studying for 4 hours is better than studying for 1, there is still the question of how to use the 4 hours. For example, is it better to study for 4 hours straight or to study for 1 hour a day for 4 days in a row? The answer, as you may have suspected, is that it is better to spread out the study times. This phenomenon through which we can learn more efficiently by dividing our practice time is known as the distribution of practice effect. Thus, our second rule of learning is this. It's better to study fairly briefly but often. But we are not finished yet. We haven't considered how we should study over very short periods of time. Let's say you are trying to learn some new and rather difficult English vocabulary using a stack of cards. Should you look at the same word in rapid succession or look at the word and then have some delay before you look at it again? The answer is it is better to space up the presentations of the word you are to learn。

Crime is increasing worldwide. There is every reason to believe the trend will continue through the next few decades. Crime rates have always been high in multi-cultural industrialized societies such as the United States. But a new phenomenon has appeared on the world scene: rapidly rising crime rates in nations that previously reported few offences. Street crimes such as robbery, rape, murder and auto theft are clearly rising, particularly in Eastern European countries, such as Hungary, and in Western European nations, such as the Untied Kingdom. What is driving this crime explosion? There are no simple answers. Still, there are certain conditions associated with rising crime. Increasing heterogeneity of population, greater cultural pluralism, higher immigration, democratization of governments, changing national borders, greater economic growth and the lack of accepted social ideas of right and wrong. These conditions are increasingly observable around the world. For instance, cultures that were previously isolated and homogenous, such as Japan, Denmark and Greece, are now facing the sort of cultural variety that has been common in America for most of its history. Multiculturalism can be a rewarding, enriching experience, but it can also lead to a clash of values. Heterogeneity in societies will be the rule in the 21st century, and failure to recognize and plan for such diversity can lead to serious crime problems.

We’re now witnessing the emergence of an advanced economy based on information and knowledge. Physical labor, raw materials, and capital are no longer the key ingredients in the creation of wealth. Now, the vital raw material in our economy is knowledge. Tomorrow’s wealth depends on the development and exchange of knowledge. And individuals entering the workforce offer their knowledge, not their muscles. Knowledge workers get paid for their education and their ability to learn. Knowledge worker engage in mind work. They deal with symbols: words, figures, and data.
What does all this mean for you? As a future knowledge worker, you can expect to be generating, as well as exchanging information. Currently, there out of four jobs involve some form of mind work, and that number will increase sharply in the future. Management and employees alike will be making decisions in such areas as product development, quality control, and customer satisfaction.
In the new world of work, you can look forward to being in constant training to acquire new skills that will help you keep up with improved technologies and procedures. You can also expect to be taking greater control of your career. Gone are the nine-to-five jobs, lifetime security, predictable promotions, and even the conventional workplace, as you are familiar with. Don’t expect the companies will provide you with a clearly defined career path. And don’t wait for someone to “empower” you. You have to empower yourself.

More and more of the world’s population are living in towns or cities. The speed at which cities are growing in the less developed countries is alarming. Between 1920 and 1960, big cities in developed countries increased two and a half times in size, but in other parts of the world the growth was eight times their size. The sheer size of growth is bad enough, but there are now also very disturbing signs of trouble in the comparison of percentages of people living in towns and percentages of people working in industry. During the 19th century, cities grew as a result of the growth of industry. In Europe, the proportion of people living in cities was always smaller than that of the work force working in factories. Now, however, the reverse is almost always true in the newly industrialized world. The percentage of people living in cities is much higher than the percentage working in industry. Without a base of people working in industry, these cities cannot pay for their growth. There is not enough money to build adequate houses for the people that live there, let alone the new arrivals. There has been little opportunity to build water supplies or other facilities. So the figures for the growth of towns and cities represent proportional growth of unemployment and underemployment, a growth in the number of hopeless and despairing parents and starving children.

Students' pressure sometimes comes from their parents. Most parents are well meaning, but some of them aren' i very helpful with the problems their sons and daughters have in adjusting to college. And a few of them seem to go out of their way to add to their children' s difficulties. For one thing, parents are often not aware of the kinds of problems their children face. They don' t realize that the competition is keener, that the required standards of work are higher, and that their children may not be prepared for the change. Accustomed to seeing A' sandB' s on the high school report cards, they may be upset when their children' s first semester college grades are below that level. At their kindest, they may gently inquire why John or Mary isn' t doing better, whether he or she is trying as hard as he or she should, and so on. At their worst, they may threaten to take their children out of college, or cut off funds. Sometimes parents regard their children as extensions of themselves, and think it only right and natural that they determine what their children do with their lives. In their involvement and identification with their children, they forget that everyone is different, and that each person must develop in his or her own way. They forget that their children, who are now young adults, must be the ones responsible for what they do and what they are.本回答被网友采纳
