名校课堂系列答案Suppose that we lined up our roughly 14 million United States businesses in order of size, starting with the smallest, along an imaginary road from San Francisco to New York. There will be 4,500 businesses to the mile, or a little less than one per foot. Suppose further that we planted a flag each business. The height of the flag pole represents the yearly volume of sales (销量) , each $ 10, 000 in sales in shown by one foot of pole.
The line of flagpoles is a very interesting sight. From San Francisco to about Reno, it is almost unnoticeable, a row of poles about a foot high. From Reno eastward the poles increase in height until, near Columbus, Ohio - about four - fifths of the way across the nation - flags fly about 10 feet in the air.
But as we approach the eastern terminus (终点) , the poles suddenly begin to mount (升高) . There are about 300, 000 firms in the country with sales over $ 500, 000. These firms take up the last 75 miles of the 3,000 - mile road. There are 200, 000 firms with sales over $ 1 million. They take up the last 50 miles. Then there are 1, 000 firms with sales of $ 50, 000, 000 or more. They take up the last quarter of a mile before the city limits, flags flying at cloud height, 5 , 000 feet up .
At the very gate of New York, on the last 100 feet of the last mile , we find the 100 largest industrial firms . They have sales of at least $ 1.5 billion, so that their flags are already miles high. Along the last 10 feet of road , there are 10 largest companies . Their sales are roughly $ 10 billion and up : their flags fly 190 miles in the air , almost in the stratosphere (平流层) .

NBA commissioner David Stern was in Orlando on Thursday night, getting ready for Sunday’s All-Star Game. Of course, all he could talk about was the only player anyone wants to talk about these days: New York Knicks guard Jeremy Lin.
Hours before Lin took the court against the Heat, a few hundred miles South down I-95 in Miami, Stern told reporters that Lin’s instant popularity hasn’t ever been matched in sports history, not even by Sunday’s biggest names, LeBron James or Kobe Bryant.
The Associated Press had the details.
“I haven’t done a calculation, but it’s fair to say that no player has created the interest and the craze in this short period of time, in any sport, that I’m aware of like Jeremy Lin has,” Stern said Thursday.
Lin, an undrafted(未选秀的)guard from Harvard, has become the NBA’s biggest story since coming off the Knicks’ bench earlier this month to lead them to nine wins in 11 games heading into their matchup with Miami on Thursday night.
With Lin’s popularity in Asia as the league’s first American-born player of Chinese or Taiwanese descent, and with the religious community because of his strong Christian faith, Stern says he’s “never quite seen anything like” the attention on Lin.
“It’s fascinating,” Stern said after the All-Star Jam Session opening ceremonies.
The top five videos on NBA.com since Feb. 4, when Lin joined the circulation, are all Lin or Knicks related. Lin went from 190,000 followers on Sina, China’s version of Twitter, on Feb. 2 to more than 1 million as of Feb. 16.
Indeed, Lin’s popularity is so out of this world that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday, a game that includes the NBA’s best rookies(新秀球员)and sophomores. Lin is in such high demand that all of the game’s other participants will meet with the media following a team practice on Friday while Lin will have his own, separate press conference later in the night.
This is Jeremy’s world, folks. We’re all just living in it. Even David Stern and the rest of the league’s All-Stars, at least for the moment.
【小题1】The following statements about Jeremy Lin’s instant popularity are true EXCEPT that ______.
| A．Jeremy Lin led New York Knicks to win all the recent games this month |
| B．David Stern said Lin was the only instant popular player in NBA’s history |
| C．Lin has become the NBA’s greatest story though he was an undrafted guard |
| D．no player has created the interest and the enthusiasm in such a short period of time |
A. Because Jeremy Lin was born in Taiwan with strong Christian faith.
B. Maybe because he is the first player born in America but has Chinese descent.
C. Because Sina has a large group of surfing people, maybe more than 10 million.
D. Because the top five videos on NBA. com since Feb. 4 are all Lin or Knicks related.
【小题3】The underlined phrase “out of this world” in Paragraph 9 may probably be replaced by ______.
| A．impossible | B．important | C．exceptional | D．excellent |
| A．Knowledge starts with practice. | B．Failure is the mother of success. |
| C．Every dog has its day. | D．No pains, no gains. |
Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes，accompanied by an article from the local paper, has made a northern German city believe in fairytales (童话）
The first envelope was sent to a victim support group. It contained ?10,000 with a cutting from the Braunschtveiger Zeitung about how the group supported a woman who was robbed of her handbag； similar plain white anonymous (匿名）envelopes, each containing ?10,000, then arrived at a kindergarten and a church.
The envelopes keep coming, and so far at least ?190,000 has been distributed. Last month, one of them was sent to the newspaper’s own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of ?500 inside , with a copy of the article. The name of the family was underlined.
"I was driving when I heard the news,” Claudia Neumann, the boy’s mother, told DerSpiegel magazine. “I had to park on the side of the road； I was speechless. ”
The money will be used to make the entrance to their house wheelchair-accessible .and for a course of treatment that their insurance company refused to pay for.
“For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.
Henning Noske, the editor of the Braunschweiger Zeitung, said： “Maybe it is an old person who is about to die. We just do not know. ” However, he has told his reporters not to look for the city’s hero, for fear that discovery may stop the donations.
【小题1】The Braunschweiger Zeitung is the name of .
| A．a church | B．a bank | C．a newspaper | D．a magazine |
| A． The donation amounted to ?190,000. |
| B．The donation was sent directly to his house. |
| C．The money will be used for his education. |
