Passage Five
Memory is the ability to keep track of things that have happened in the past. Memory really is leaning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called.
Memory is said to be stored in the brain as a “memory trace (记忆痕) .” What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to dear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means to find out how a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Gibe the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize thins that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as a measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learn how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.
52. We can learn from the 2nd paragraph that_____.
A bad memories may cause rats to fear the dark
B it is hard to tell what a memory trace consists of
C chemical substances carry certain memories
D memory is stored in the brain as a substance
There's Bill Gates, who these days is spending less time earning money than giving it away—and pulling other billionaires into the deep end of global philanthropy(慈善事业) with him. There's historian Francis Fukuyama, leading a whole gang of disaffected fellow travelers away from neoconservatism. To flip-flopis human. It can still sometimes be a political liability, evidence of a flaky disposition or rank opportunism. But there are circumstances in which not to reverse course seems almost pathological(病态的). He's a model of consistency, Stephen Colbert said last year of George W. Bush:" He believes the same thing Wednesday that he believed on Monday—no matter what happened on Tuesday".
Over the past three years, I found people who had pulled a big U-turn in their lives. Often the insight came in a forehead-smiting moment in the middle of the night: I've got it all wrong.
It looked at first like a sprinkling of outliers beyond the curve of normal human experience. But when you stepped back, a pattern emerged. What these personal turns had in common was the apprehension that we're all connected. Everything leans on something, is both dependent and depended on.
"The difference between you and me", a visiting Chinese student told University of Michigan psychologist Richard Nisbett not long ago", is that I think the world is a circle, and you think it's a line". The remark prompted the professor to write a book, The Geography of Thought, about the differences between the Western and the Asian mind.
To Western thinking, the world is linear; you can chop it up and analyze it, and we can all work on our little part of the project independently until it's solved. The classically Eastern mind, according to Nisbett, sees things differently: the world isn't a length of rope but a vast, closed chain, incomprehensibly complex and ever changing. When you look at life from this second perspective, some unlikely connections reveal themselves.
I realized this was what almost all the U-turns had in common: people had swung around to face East. They had stopped thinking in a line and started thinking in a circle. Morality was looking less like a set of rules and more like a story, one in which they were part of an ensemble cast, no longer the star.
What can we infer from first two paragraphs？
A．Some people have changed into someone another.
B．Rhere are some drugs that can change one's identity.
C．Some moneybags are pulled to act as philanthropist.
D．francis Fukuyama has become a great traveler.
