Passage Two
| Americans usually consider themselves a friendly people. Their friendships, however, tend to be shorter and more casual than friendships among people from other cultures. It is not uncommon for Americans to have only one close friend during their lifetime, and consider other "friends" to be just social acquaintances. This attitude probably has something to do with American mobility and the fact that Americans do not like to be dependent on other people. They tend to "compartmentalize" (划分) friendships, having "friends at work", "friends on the softball team", "family friends", etc. Because the United States is a highly active society, full of movement and change, people always seem to be on the go. In this highly charged atmosphere, Americans can sometimes seem brusque (无礼的) or impatient. They want to get to know you as quickly as possible and then move on to something else. Sometimes, early on, they will ask you questions that you may feel are very personal. No insult is intended; the questions usually grow out of their genuine interest or curiosity, and their impatience to get to the heart of the matter. And the same goes for you. If you do not understand certain American behavior or you want to know more about them, do not hesitate to ask them questions about themselves. Americans are usually eager to explain all about their country or anything "American" in which you may be interested. So much so in fact that you may become tired of listening. It doesn’t matter, because Americans tend to be uncomfortable with silence during a conversation. They would rather talk about the weather or the latest sports scores, for example, than deal with silence. On the other hand, don’t expect Americans to be knowledgeable about international geography or world affairs, unless those subjects directly involve the United States. Because the United States is not surrounded by other nations, some Americans tend to ignore the rest of the world. |
It can be inferred from the passage that ______.
A．Americans’ character is affected by their social and geographical environment
B．Americans want to participate in all kinds of activities
C．curiosity is characteristic of Americans
D．Americans do not know how to deal with silence

The very wealthy English Baron Fitzgerald had only one child, a son, who understandably was the
apple of his eye. His wife died when the child was in his early teens. So Fitzgerald devoted himself to
fathering the kid. Unfortunately the son died in his late teens.
Meanwhile, Fitzgerald's wealth greatly increased. He spent a lot on art works of the masters. Later
Fitzgerald himself became seriously ill. Before his death, he had carefully prepared his will as to how his
wealth would be settled-to sell his entire collection at an auction(拍卖).
Because of the large quantity and high quality of his collection, a huge crowd of possible buyers
gathered for the auction. Many of them were museum directors and private collectors eager to bid(出
价). Before the auction, the art works were shown, among which was a painting of Fitzgerald's son by
an unknown artist. Because of its poor quality, it received little attention.
When it was time for the auction, the auctioneer gaveled(敲槌)the crowd to attention. First the
lawyer read from Fitzgerald's w
ill that the first art work to be auctioned was the painting of his son.
The poor-quality painting didn't receive any bidders. . . except one-the old servant who had served
the son and loved him, and who for emotional reasons offered the only bid.
As soon as the servant bought the painting for less than one English pound, the auctioneer stopped
the bidding and asked the lawyer to read again from the will. The crowd became quiet, and the l
awyer
read from the will: "Whoever buys the painting of my son gets all my collection. "Then the auction was
over.
