But do you know memory is the single most important thing and it has played a very important part? For early men, there were dangerous all around them-bad weather, wild animals. The keys to keep on living lay in mans ability to remember these dangers and the ways he had dealt with them in the past. In order for memories to be stored, the human brain became more complex. And as man learned how to deal with them, he became civilized (文明).Surprisingly, scientists today understand little about memory and how it works. They have not yet found a way to open up the brain and observe its function without destroying it. Perhaps there are two types of memory: short-term and long-term. Short-term refers to those facts that stay with us for a few seconds to a few hours. For instance, when you stay at a hotel, you remember the room number and forget as soon as you leave. Long-term memory, on the other hand, means you remember things for a long period of time. If you spend your honeymoon in a particular hotel, its likely that youll remember your stay quite clearly.Scientists also believe that a short-term memory can become a long-term memory through consolidation(巩固). A lot of chemical and physical changes take place in the part of the brain. Although the human brain weighs three pounds, it contains 30 billion nerve cells(神经细胞) acting like a computer. When those changes strengthen the links(联系) in certain nerve cells, a though becomes a part of the long-term memory.36. According to the author, without the development of mans memory there would be _.A. no modern world B. no recorded history C. no animals D. no dangers37. Scientists knowledge about the function of brain is _.A. interesting B. not enough C. great D. encouraging38. Short-term memory can change into long-term memory on condition that _.A. memory is good B. it acts like a computerC. people do more exercise D. the links in nerve cells are strengthened by certain changes39. So far the great discovery scientists have made about the function of brain is _.A. the weight of brain B. two types of memoryC. 30 billion nerve cells D. chemical and physical changesBWhen we hear the words “ college students”, we usually think of a young person between 18 and 22 years old. But in the U.S.A today, a college student often is much older. In fact, educators say in the next few years colleges and universities may have more older part-time students than traditional (传统的) full-time younger students.Educators report a big increase in the number of Americans who attend college and university classes in the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-time jobs. Many are in their thirties or forties.Why are so many people deciding to spend their time and money in order to continue their education?

Some have retired (退休) and are looking for new kinds of work. Two of every three of the students older than 35 are women. Many of them are returning to school after years of staying at home to care for children.Are older students good students? Most teachers say yes. They say older students really want to learn.
