24.Cars are an important part of life in th United States.Without a car, most people feel that they are poor.An even if a person is poor he doesn't feel really poor when he has a car.Henry Ford was the man who first started making cars in large numbers.He probably didn't know how much the car was going to affect American culture.The car made the Unite States a nation on wheels.And it helped make the United States what it is today.There are three main reasons the car became so popular in the United States.First of all,the country is a huge one and Americans like to move around in it.The car provides the most comfortable and cheapest form of transportation.With a car people can go any place without spending a lot of money.The second reason cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation.Long-distance have never been as common in the United States as they are in other parts of the world.Nowadays,there is a good system of air-service provided by planes.But it is too expensive to be used frequently.The third reason is the most important one,though.The American spirit of independence is what really made cars popular.Americans don't like to wait for a bus or a train or even a plane.They don't like to have to follow an exact schedule.A car gives them the freedom to schedule their own time.And this is the freedom that Americans want most to have.The gas shortage has caused a big problem for Americans.But the answer will not be a bigger system of public transportation.The real solution will have to be a new kind of car,one that does not use so much gas.(10分)24.1 When do most Americans feel they are poor?(2分)A. When they don't have a carB. When they live in a huge countryC. When they don't planes.D. When they have a car

1. Strange thing happens to time when you travel. Because the earth is divided into twenty-four time zones one hour apart, you can have days with more or fewer than twenty-four hours, and weeks with more or fewer than seven days.If you make a five-day trip across the Atlantic Ocean, your ship enters a different time zone every day. As you enter each zone, the time changes the hour. Travelling west, you set your clock back; travelling east, you set it ahead. Each day of your trip has either twenty-five or twenty-three hours.If you travel by ship across the Pacific you cross the international date line. By agreement, this is the point where a new day begins. When you cross the line, you change your calendar the full day, backward or forward. Travelling east, today becomes yesterday; travelling west, it is tomorrow! 21. The best title for this selection is____.A. A Trip Across the AtlanticB. How Time Changes Around the World C. Crossing the International Date LineD. How Time Zones Were Set Up

2. A railroad was being built all the way down the east coast off Florida, from Jacksonville to Miami and Negro workers were employed because they were cheap. A great many of them were in Daytona. Most of them had children. They were living in shacks worse than those in The Terry in Augusta. The children were running wild in the streets. Mary Bethune seemed to hear a voice say, "What is the place? Build your school there."Her husband, Albertus, wasn't so sure about her school. He thought Palatka was a pretty good place for them to live. Mary listened but she never gave up her idea. She knew that if she went to Daytona, Albertus would come too.One day she begged a ride for herself and her little boy with a family that was going to Daytona. It was only seventy miles away. But in 1904 the sand was deep on Florida roads. Practically no one had an automobile -- certainly not the poor family that gave Mary and little Albert a ride. So it was three dusty days after they left Palatka before they reached Daytona. There Mary hunted up the only person she knew, and she and little Albert stayed with this friend for a few days.As she had done in The Terry in Augusta, Mary walked up and down the poor streets of Daytona. She was looking for two things -- a building for the school she was determined to start and some pupils for that school.After a day or two, she found an empty shack on Oak Street. She thought this would do. The owner said she could rent it for $11.00 a month. But it wasn't worth that much. The paint had peeled off, the front steps wobbled so that she had to hang onto the shaky railing to keep from falling, the house was dirty, it had a leaky roof. In most of the windows the panes of glass were broken or cracked.Eleven dollars a month ! Mary said she only had Times="10".50. She promised to pay the rent as soon as she could earn the money. The owner trusted her. By the time she was sure she could have the building, she had five little girls from the neighborhood as her pupils.What a school! A rickety old house and five little girls! The little girls pitched in and cleaned the house. The neighbors helped with scrubbing brushes, brooms, hammers, nails, and saws. Soon the cottage could be lived in, but there were no chairs, no tables, no beds. There was no stove. However, there were no pots and pans to cook in, even if there had been a stove.Mary set about changing these things. She found things in trash piles and the city dump. Nobody but Mary would have thought of making tables and chairs and desks from the old crates she picked up and brought home. Behind the hotels on the beach she found cracked dishes, old lamps, even some old clothes. She took them home too. Everything was scoured and mended and used. "Keep things clean and neat" was her motto then; and as long as she lived the pupils in her school had to live up to that motto.Her little pupils had no pencils. They wrote with pieces of charcoal made from burned logs. Their ink was elderberry juice. What good was ink or a pencil if there was no paper to write on? Mary took care of that too.Every time she went to the store to get a little food, or a few pots and pans, she had each article wrapped separately. The pieces of wrapping paper were carefully removed and smoothed out. The little girls used this paper to write their lessons with their charcoal pencils.She needed a cookstove very badly but she couldn't pay for one. What should she do? Her little pupils had to have warm food.Unexpectedly, the problem was solved for her. One day a wrinkled old white neighbor said to her, "Can you read?"Mary said, "Yes.""Then will you read me this letter from my son? I can't find my glasses."Mary read the letter to her."Thanks," said the mother.Mary turned to go. "You're welcome."The old woman stood by her open door and thought a moment. Then she said, "I got an old cookstove and I don't need it. Would you want it?"(5分)2.1How did Mary's husband, Albertus feel about going to Daytona?____(1分)A. He was strongly in favour.B. He was quite reluctant.C. He was definitely against it.D. He was not happy about the idea.
