When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses．This phenomenon is referred to as the bystander effect．

       The bystander effect is also called the Genovese effect, which was named after Catherine Kitty Genovese, a．young woman who was murdered on March 13, 1964．Early in the morning, 28-year-old Genovese was returning home from work．As she approached her apartment entrance, she was attacked and stabbed（刺）by a man later identified as Winston Moseley．Despite Genovese]s repeated cries for help , none of the dozen or so people in the nearby apartment building who heard her cries called the police for help ．The attach first began at 3:20 , but it was not until 3:50 that someone first contacted the police．

       There are two major factors that contribute to the bystander effect．First, the presence of other people creates a diffusion（分散）of responsibility．Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present．

       The second reason is the need to behave in correct and socially acceptable ways．When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate．Other researchers have found that onlookers are less likely to take action if the situation, is ambiguous^ R^E^?）．In the case of Kitty Genovese, many of the 38 witnessing reported that they believed that they were witnessing a " lovers' quarrel" , and did not realize that the young woman was actually being murdered．

The passage seems to suggest that Genovese might not have been murdered if there had been_____．

       A．no observer                 B．fewer observers 

       C．more observers ．   D．younger observers

Genovese was murdered                    .

       A．while she was going out        B．in her apartment

       C．halfway home           D．in front of her apartment ?

The underlined word "this" in the last paragraph probably refers to ____．

       A．not doing anything to help      B．behaving in correct ways

       C．taking action           D．murdering

We can learn from the passage that Genovese's neighbors didn't lend a hand partly because they ____．

       A．were afraid of being attacked by the murderer

       B．thought someone else might come to her rescue．

       C．didn't get along well with her

       D．were sure it was murdering

Since my retirement(退休) from teaching music in 2001, I have spent a good deal of time painting as an artist. I actually began drawing again in the summer of 1995 when my father died, so perhaps I was trying to recover from the loss of my father, or maybe it was just that it brought back memories of him. In any case, I drew pen and ink animals and landscapes(风景画) much influenced(影响) by Krenkel and St. John for five years.

For some strange reason, I had been waiting until my retirement to start doing watercolors again, but as soon as I walked out of the school door for the last time I picked up my brushes and rediscovered Andrew Wyeth, who quickly became my favorite artist. I had looked through all the art books I had on my shelves and found his watercolors to be the closest to how I thought good watercolors should look. So I painted landscapes around Minnesota for three years and tried out many other types of painting. However, watercolors remained my first choice, and I think I did my best work there, showing my paintings at a number of art exhibitions.

Art is now together with my piano playing and reading. There is a time for everything in my world, and it is wonderful to have some time doing what I want to do. As Confucious once said, “At seventy I can follow my heart’s desire.”

A well-dressed man entered a famous jewelry shop. He explained that he wished to buy a pearl for his wife’s birthday. The price didn’t matter. Since business had been very good for him that year. After examining a nice black one that cost $5000, he paid for the pearl in cash, shook hands with the jeweler, and left.

A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality, as she wanted a pair of earrings made, “Can you give me any advice on how to get such a pearl?” said the man. The jeweler regretfully replied, “I would say it’s exactly impossible to find one exactly like that pearl.”

The rich man insisted that the jeweler advertise in the newspapers, offering $ 25,000 for the matching pearl. Many people answered the advertisement but nobody had a pearl that was just right.

Just when the jeweler had given up hope, a little old lady came into his store. To his great surprise, she pulled the perfect pearl from her purse. “I don’t like to part with it,” she said sadly, “I inherited it from my mother, and my mother inherited it from hers. But I really need the money.”
