     For a long time, a boy wondered why his next-desk classmate was always the first in the class,
while he could only rank (排名) the 21st. At home, he asked his mom, " Am I more stupid than other
kids? How come I always fall behind?I can't come up with an answer. " Mom knew that her son's
self-respect (自尊心) had been hurt by the ranking system, but she didn't know what to say to help.
    She had really wanted to say that intelligence (智力) differs and that yes, her son's friend was really
a smarter boy. But that would make her son lose heart. So she didn't say it.
    Her son and his friend went on to a high school that year. Although her son tried as hard as he could,
his friend still left him behind. But she was proud of her boy for his hard work. It was around this time
she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.
Today her son no longer cares about rankings. He doesn't have to, for he himself is now at the top of the
class in a university. When invited to his old high school, he mentioned a valuable childhood experience:
Once on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to
me: Do you see seabirds fighting for food out there?When a wave (海浪) comes near, the little birds
rise quickly. The "clumsy"  seagulls (海鸥) are far less quick and have to tried hard to get away from the
wave. But they prove to have the biggest, strongest wings,which open the widest and allow the bird to
travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind.
Son, I have feeling that you are one of those seagulls. "

In the 1920s and 30s the airlines were just beginning. It was unusual for people to travel by air because it was expensive and dangerous. In those days, there were no flight attendants to look after the passengers(乘客). Young men ,or “stewards” helped the passengers onto the airplane and carried the passengers’ luggage(行李)but they did not provide food or drinks. But then in 1930,a woman called Ellen Church invented the “stewardess”.

Ellen Church was born in 1904 on a farm in Iowa. She was a different child. She didn’t want to work on a farm or marry a farmer —she wanted a more adventurous life. Ellen studied to be a nurse at the University of Minnesota and then got a job in a hospital. For the next few years she stayed at the hospital but also took flying lessons and got her pilot’s license.

Ellen was twenty-five years old when she first got in touch with Boeing Air Transport. She loved flying but she understood that airlines were a man’s world. Although women like Emelia Earheart were becoming famous, she realized it was impossible for a woman to have a career as a pilot .But she had another idea. Most people were frightened of flying because. flying was still an unreliable(不可靠的) way to travel. There were often delays(延误),many crashes and the bad weathers made many passengers sick. Ellen thought nurses could take care of passengers during flights and B.A.T. agreed.

The young woman from Iowa and seven other nurses became the first air stewardesses.

At first pilots were unhappy because they did not want stewardesses on airplanes, but passengers loved the stewardesses. In 1940 there were around 1000 of them working for different airlines. The early “stewardesses” had to be under twenty-five-year-old, single and slim. When a woman joined an airline, she had to promise not to get married or have children. It was a hard job and not well paid. They worked long hours and earned 1 an hour.

In the 1970s, stewardesses were unhappy in their job and airlines had to make some changes. Since the 1970s, “stewardesses” have been called flight attendants. They are well paid and work fewer hours than in the past.

1.The underlined word “adventurous” means _____________.

A. 奇怪的?????? B. 平淡的????? C. 有趣的????? D. 冒险的

2.The main reason for Boeing Air Transport offering Ellen the job was ________.

A. her flying experience????????????? ????????????? ????????????? B. her university education

C. her nursing experience ????????????? ????????????? D. her life attitudes

3.According to the passage, in the 1940s a woman had to ________ if she wanted to be a stewardess.

A. be a nurse????????????? ????????????? ????????????? B. be married????????????? ????????????? C. be a mother????????????? ????????????? ????????????? D. be young

4.The passage mainly talks about _______.

A. the background of early flying pilots????????????? ?????????????

B. the experience of flying passengers

C. the history of early flight attendants????????????? ?????????????

D. the development of airplanes????????????? ?????????????
