　　对于梦的起源的探讨(摊手)

　　M：Do you think dreams have special meanings?

　　W：No, I don't think they do.

　　M：Don't either. But some people do. I would say people who believe that dreams have meanings are superstitious, especially nowadays, in the past, during the times of ancient Egypt, Greece or China, people used to believe that dreams could foresee the future. But today, with all the scientific knowledge that we have, I think it's much harder to believe in these sorts of things.

　　W：My grandmother is superstitious, and she thinks dreams can predict the future. Once she dreamed that the flight she was due to take the following day crashed, can you guess what she did? She didn't take that flight. She didn't even bother to go to the airport the following day. Instead she took the same flight. But a week later, everything was fine. Of course, no plane ever crashed.

　　M：How funny did you know that flying is actually safer than any other mode of transport? It's been statistically proven. People can be so irrational sometimes.

　　W：Yes, absolutely. But even if we think they are ridiculous, emotions can be just as powerful as rational thinking.

　　M：Exactly. People do all sorts of crazy things because of their irrational feelings. But in fact, some psychologists believe that our dreams are the result of our emotions and memories from that day. I think it was Sigmund Freud who said that children's dreams were usually simple representations of their wishes, things they wished would happen. But in adults, dreams a much more complicated reflections of their more sophisticated sentiments.

　　W：Isn't it interesting how psychologists try to understand using the scientific method something as bizarre as dreams? Psychology is like the rational study of irrational feelings.

　　到底什么是激进?女权主义是激进嘛?

　　What is a radical? It seems today that people are terrified of the term, particularly of having the label attached to them. Accusing individuals or groups of being radical often serves to silence them into submission, thereby maintaining the existing state of affairs, and more important, preserving the power of a select minority who are mostly wealthy white males in western society.

　　Feminism is a perfect example of this phenomenon. The women's movement has been plagued by stereotypes, misrepresentations by the media, and accusations of man hating and radicalism. When the basic foundation of feminism is simply that women deserve equal rights in all facets of life, when faced with a threat of being labeled radical women back down from their worthy cause and consequently participate in their own oppression, it has gotten to the point that many women are afraid to call themselves feminists because of the stigma attached to the word. If people refuse to be controlled and intimidated by stigma, as the stigma as lose all their power, without fear and which to feed such stigma as can only die. To me, a radical is simply someone who rebels against the norm. What advocates a change in the existing state of affairs? On closer inspection, it becomes clear that the norm is constantly involving and therefore is not a constant entity.

　　So why there is deviation from the present situation? Such a threat than the state of affairs itself is unstable. And subject to relentless transformation, it all goes back to maintaining the power of those who have it and preventing the rise of those who don't. In fact, when we look at the word radical in a historical context, nearly every figure we now hold up as a hero was considered a radical in his or her time. Radicals are people who affect change. They are the people about whom history is written. Abolitionists were radicals. Civil rights activists were radicals, even the founders of our country in their fight to win independence from England or radicals. Their presence in history has changed the way our society functions, mainly by shifting the balance of power that previously existed. There are some radicals who have made a negative impact on humanity. But undeniably, there would simply be no progress without radicals. That being said, next time someone calls me a radical, I will accept that label with pride.

　　Questions 16 to 18 are based on the recording you have just heard.

　　Question 16. What usually happens when people are accused of being radical?

　　答案：preserving the power of a select minority who are mostly wealthy white males in western society.

　　Question 17. What is the speaker's definition of a radical?

　　答案：a radical is simply someone who rebels against the norm.

　　Question 18. What does the speaker think of most radicals in the American history?

　　答案：there would simply be no progress without radicals.

　　人的社会性因素：不可避免的被环境影响

Two weeks later, Fred is taking 20 minute breaks. A month later, Fred takes his half hour. Fred is saying, if you can't beat them, join them, why should I work any harder than the next guy?

　　The fascinating thing about being human is that generally we are unaware that there are changes taking place in our mentality. It is like returning to the city smog after some weeks in the fresh air. Only then do we realize that we have become accustomed to the nasty smells mix with critical people. And we learn to criticize mixed with happy people. And we learn about happiness. What this means is that we need to decide what we want from life and then choose our company accordingly.

　　You may well say that is going to take some effort. It may not be comfortable. I may offend some of my present company. Right? But it is your life. Fred may say I'm always broke frequently depressed. I'm going nowhere and I never do anything exciting. Then we discover that friends, best friends, are always broke, frequently depressed, going nowhere and wishing that life was more exciting. This is not coincidence. Nor is it our business to stand in judgment of Fred. However, if Fred ever wants to improve his quality of life, the first thing he'll need to do is recognize what has been going on all these years. It's no surprise that doctors as a profession suffer a lot of ill health because they spend their lives around sick people. Psychiatrists have a higher incidence of suicide in their profession for related reasons.

　　美元的发展历史

　　Virtually every American can recognize a dollar bill at a mere glance. Many can identify it by its sound or texture. But few people indeed can accurately describe the world's most powerful, important currency. The American dollar bill is colored with black ink on one side and green on the other. The exact composition of the paper and ink is a closely guarded government secret. Despite its weighty importance, the dollar bill actually weighs little. It requires nearly 500 bills to tip the scales at a pound. Not only is the dollar bill lightweight, but it also has a brief lifespan. Few dollar bills survive longer. 18 months.

　　The word dollar is taken from the German word, tailor the name for the world's most important currency in the 16th century.

　　The Thaler was a silver coin first minted in 1518 under the reign of Charles the 5th, emperor of Germany.

　　The concept of paper money is a relatively recent innovation in the history of American currency. When the constitution was signed, people had little regard for paper money because of its steadily decreasing value during the colonial era. Because of this lack of faith, the new American government minted only coins for common currency. Interest bearing bank notes were issued at the same time. But their purpose was limited to providing money for urgent government crises, such as American involvement in the war of 1812. The first non interest bearing paper currency was authorized by congress in 1862. At the height of the civil war. At this point, citizens, old fears of devalued paper currency had calmed. The dollar bill was born. The new green colored paper money quickly earned the nickname greenback. Today, the American dollar bill is a product of the federal reserve and is issued from the 12 federal reserve banks around the United States. The government keeps a steady supply of approximately 2 billion bills in circulation at all times.

　　Controversy continues to surround the true value of the dollar bill.

　　American history has seen generations of politicians argue in favor of a gold standard for American currency. However, for the present, the American dollar bill holds the value that is printed on it and little more. The only other guarantee on the bill is a federal reserve pledge as a confirmation in the form of government securities.

　　答案：The American dollar bill is colored with black ink on one side and green on the other
