Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Passage OneQuestions 1 to 5 are based on the following passage:Plastics are materials which are softened by heat and set into lasting from when shaped in a mold. Some are natural; some are semi-synthetic, the result of chemical action on a natural substance; some are synthetic, built up from the constituents of oil or coal. All are based on the chemistry of carbon, with its capacity for forming chains. The molecules that compose them (monomers) link together in the setting or curing (固化) process to form chains (polymers), which give plastics their flexible strength. Some plastics retain their ability to be softened and reshaped; like wax, they are thermoplastic. Others set permanently in the shapes they are given by heat and pressure; like eggs, they are thermosetting.From industrial beginnings in the nineteenth century, plastics have struggled through a hundred and twenty years of glory, failure, disrepute (坏名声) and suspicion on the slow road to public acceptance. Now, at last, one can positively say that plastics are appreciated and enjoyed for what they are; that they make modern life richer, more comfortable and convenient and also more funny. Plastics are warm materials, sympathetic to the human touch, and their transformation into things that come into contact with human beings is entirely appropriate.The fact that there plastic antiques comes as a shock to most people. How can a material that seems so essential in the twentieth century, and one that is so much associated with cheap disposable products, have a history at all? It is a young technology, and a great part of the fun of collecting plastics is that beautiful pieces of historical interest can still found very cheaply.1. Which of the following is the best title for the passage?A) The development of Plastics as a Modern MaterialB) How Plastics Are MaterialC) The Importance of Plastics in the Nineteenth CenturyD) Why people Are Suspicious of Plastics2. Which of the following is necessary to create any type of plastics?A) Coal.B) Eggs.C) Oil.D) Carbon.3. According to the author, for approximately how many years have plastics existed?A) 160.B)120.C)140.D) 100.4. What historical information does the second paragraph give about plastics?A)They originated primarily as road-surfacing materials.B) The earliest types were soft and did not last very long.C)Their popularity was at its height at the time of the Industrial Revolution.D) They have come into general use very gradually.5. Why does the author mention antiques in the third paragraph?A) Young collectors prefer real antiques to plastic objects.B) Dealers use inexpensive plastic parts to repair valuable antiques.C) Some plastic objects are now considered antiques.D) Plastics replicas (复制品) of valuable antiques are relatively common.Passage TwoQuestions 6 to 10 are based on the following passage:When memory began for me, my grandfather was past sixty -- a great tall man with thick hair becoming gray. He had black eyes and a straight nose which ended in a slightly flattened tip. Once he explained seriously to me that he got that flattened tip as a small child when he fell down and stepped on his nose. The little marks of laughter at the corners of his eyes were the product of a kindly and humorous nature. The years of work which had bent his shoulders had never dulled his humor nor his love of a joke. Everywhere he went, ''Gramp'' made friends easily. At the end of half an hour you felt you had known him all your life. I soon learned that he hated to give orders, but that when he had to, he tried to make his orders sound like suggestions.One July morning, as he was leaving to go to the cornfield, he said, ''Edwin, you can pick up the potatoes in the field today if you want to do that.'' Then he drove away with his horses.The day passed, and I did not have any desire to pick up potatoes. Evening came and the potatoes were still in the field. Gramp, dusty and tired, led the horses to get their drink.''How many bags of potatoes were there?'' Gramp inquired.''I don't know.''''How many potatoes did you pick up?''''I didn't pick any.''''Not any! Why not?''''You said I could pick them up if I wanted to. You didn't say I had to.''In the next few minutes I learned a lesson I would not forget: when Gramp said I could if I wanted to, he meant that I should want to.My grandmother (''Gram'') worked hard all day, washing clothes, cleaning the house, making butter, and even working in the field when help was scarce. In the evening, though, she was not too tired to read books from the community library. For more than forty years Gram read aloud to Gramp almost every evening. In this way she and Gramp learned about all the great battles of history and became familiar with the works of great authors and the lives of famous men.Gram hated cruelty and injustice. The injustices of history, even those of a thousand years before, angered her as much as the injustices of her own day.She also had a deep love of beauty. When she was almost seventy-five, and had gone to live with one of her daughters, she spent a delightful morning washing dishes because, as she said, the beautiful patterns on the dishes gave her pleasure. The birds, the flowers, the clouds -- all that was beautiful around her -- pleased her. She was like the father of the French painter, Millet, who used to gather grass and show it to his son, saying, ''See how beautiful this is!''In a pioneer society it is the harder qualities of mind and character that are of value. The softer virtues are considered unnecessary. Men and women struggling daily to earn a living are unable, even for a moment, to forget the business of preserving their lives. Only unusual people, like my grandparents, manage to keep the softer qualities in a world of daily struggle.Such were the two people with whom I spent the months from June to September in the wonderful days of summer and youth.6. We know that Grandpa's nose _________.A) was flattened because it had been stepped onB) was not flat when he was a boyC) was both straight and broadD) was straight but its tip was a bit flat7. We learn from the passage that Grandpa _________.A) was friendly and humorousB) liked making suggestionsC) loved to give ordersD) was a serious and strict person8. When Grandpa told the writer to pick up potatoes if he wanted to do that, he meant that _________.A) he could do it if he wanted toB) he did not really have to do soC) he could do it anytime he was readyD) he had to do it9. The writer describes his Grandma as _________.A) a woman who complained about the injustices of lifeB) a very obedient housewifeC) someone who could find beauty in lifeD) a woman who loved Millet's paintings10. According to the passage, in the days of the writer's grandparents _________.A) most people understood how to appreciate the beautiful thingsB) in life it was difficult for people to keep the "soft qualities" of mind and characterC) only ordinary people managed to appreciate the beauty of natureD) it was the "soft virtues" that were thought to be very importantPassage ThreeQuestions 11 to 15 are based on the following passage:Like a lot of black kids, we never would have made it without our Momma. When there was no fatback to go with the beans, no socks to go with the shoes, no hope to go with tomorrow, she’s smile and say: “We ain’t poor, we’re just broke.”Poor is a state of mind you never grow out of, but being broke is just a temporary condition. She always has a big smile, even when her legs and feet swelled from high blood pressure and she collapsed across the table with diabetes. You have to smile twenty-four hours a day, Momma would say. If you walk through life showing the aggravation you’ve gone through, people will feel sorry for you, and they’ll never respect you.So you laugh, so you smile. Once a month the big gray relief truck would poll up in front of our house and Momma would flash that big smile and stretch out her hands: “Who else you know in this neighborhood gets this kind of service?”And we could all feel proud when the neighbors, folks who weren’t on relief, folks who had Daddies in their houses, would come by the back porch fro some of those hundred pounds of potatoes, for some sugar and flour and salty fish. We’d stand out there on the back porch and hand out the food like we were in charge of helping poor people, and then we’d take the food they brought us in return.And Momma came home one hot summer day and found we’d been evicted, thrown out into the streetcar zone with all our orange crate chairs and secondhand lamps. She flashed that big smile and dried our tears and bought some penny Kool-Aid. We stood out there and sold drinks to thirsty people coming off the streetcar, and we thought nobody knew we were kicked out—figured they thought we wanted to be there. And Momma went off to talk the landlord into letting us back in on credit.But I wonder about my Momma sometimes, and all the other black mothers who got up at 6 a.m. to go to the white man’s house with sacks over their shoes because it was so wet and cold. I wonder how they made it. They worked very hard for the man, they made his breakfast and they scrubbed his floors and they diapered his babies. They didn’t have to much time for us.I wonder about my Momma, who walked out of a white woman’s clean house at midnight and came back to her own where the lights had been out for three months, and the pipes were frozen and the wind came in through the cracks. She’d have to make deals with the rats: ;eave some food out for them so they would n’t gnaw on the doors or bite the babies. The roaches, they were just live part of the family.I wonder how she felt telling those white kids she took care of to brush their teeth after they ate, to wash their hands after they peed. She could never tell her own kids because there was n’t soap or water backhome.I wonder how my Momma felt when we came home from school with a list of vitamins and pills and cod liver oil the school nurse said we had to have. Momma would cry all night, and then go out and spend most of the rent money for pills. A week later, the white man would come for his eighteen dollars rent and Momma would plead with him to wait until tomorrow. She had lost her pocketbook. The relief check was coming. The white fold had some money for her. Tomorrow, I’d be hiding in the coal closet because there was only supposed to be two kids in the flat, and I could hear the rent man curse my Momma and call her a liar.I wonder how my Momma stayed so good and beautiful in her soul when she worked seven days a week on swollen legs and feel, how she kept teaching us to smile and laugh when the house was dark and cold and she never knew when one of her hungry kids was going to ask about Daddy.I wonder how she kept from teaching us hate when the social worker cam around. She was a nasty bitch with a pinched face who said, “We have reason to suspect you are working, Miss Gregory, and you can be sure I’m going to check on you. We don’t stand for welfare cheaters.”Momma, a welfare cheater. A criminal who couldn’t stand to see her kids go hungry, or grow up in slums and end up mugging people in dark corners. I guess the system didn’t want her to get off relief, the way it kept sending social workers around to be sure Momma wasn’t trying to make things better.I remember how that social worker would poke around the house, wrinkling her nose at the coal dust on the chilly linoleum floor, shaking her head at the buds crawling over the dirty dishes in the sink. My Momma would have to stand there and make like she was too lazy to keep her own house clean. She could never let on that she spent all day cleaning another woman’s house for two dollars and carfare. She would have to follow that nasty bitch around those drafty three rooms, keeping her fingers crossed that the telephone hidden in the closet wouldn’t ring. Welfare cases weren’t supposed to have telephone.But Momma figured that some day the Gregory kids were going to get off North Taylor Street and into a world where they would have to compete with kids who grew up with telephones in their houses. She didn’t want us to be at a disadvantage. She couldn’t explain that to social worker. And she couldn’t explain that while she was out spoon-feeding somebody else’s kids, she was worrying about her own kids, that she could rest her mind by picking up the telephone and calling us-to find out if we had bread for our baloney or baloney for our bread, to see if any of us and gotten run over by the streetcar while we played in the gutter, to make sure the house hadn’t burnt down from the papers and magazines we stuffed in the stove when the coal ran out.11.
