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. Young men ,or “stewards” helped the passengers onto the airplane and carried the passengers’ luggage(行李)but they did not provide food and 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(冒险的)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 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.

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.
1.For a long time humans think ________.
A. they can surely find life on Mars
B. there may be life on Mars
C. it’s too late for them to explore Mars now
D. Mars is the only planet that has life on it
2.The two robots ________.
A. have found out that it is warm and wet on Mars
B. were sent to Mars to find some stones
C. were the first two American robots that landed on Mars
D. are the only machines that have landed on Mars so far
3.The third paragraph mainly tell us ________.
A. it’s a very hard and dangerous trip for spaceships to Mars
B. two-thirds of the spaceships sent to Mars have failed
C. Spirit and Opportunity landed on Mars successfully
D. Mars is called the “death planet”
The first part of a new science-fiction series （系列剧）was shown on NBC last night. Star Trek is about a spacecraft（宇宙飞船）which travels faster than the speed of light. The show is developed from three ideas about the 22nd century. First, we’ll find other life forms great tools which will make amazing things possible.
Let’s think about these predictions. If we find life forms on other planets, will they be intelligent? I hope so. But we human beings might not be friendly – I don’t think we’ll believe in the idea of peace one hundred years from now. But this is science fiction, so we can be optimistic! And Star Trek’s idea of life in the future is ‘communicators’. And we will be ablt to have conversatins with people who are on because you’ll have an electronic notebook. And if you get ill, the doctor won’t have to examine you – a machine will ‘read’ your body. The strangest manchine includes a ‘teleport’ which will take people to a different placein a second!
The ideas are interesting, and in my opinion there’s only one problem with star trek: the acting. The TV company （公司）will have to get better actors. If they do that, the show might be a success. If the acting doesn’t improve, Star Trek won’t last for more than one series. Of course, my prediction may be wrong. I can’t see into the future!
1. What is Star Trek?
A. A TV play. B. A popular song.
C. A spacecraft. D. An alien.
2.What does the underlined word “optimistic” mean?
A. Lucky and happy.
B. Hopeful and confident.
C. Helpful and creative.
D. Thankful and popular.
3.Which would be the best title for the passage?
A. Aliens on Other Planets. B. The Idea of Human Life.
C. A Science Fiction. D. A New Series about Future.
