Introductory Chemistry was taught at Duke University for many years by professor Bonk. One year, two guys took the class and did pretty well on all the quizzes and mid-terms. They each had a solid A. These two friends were so confident in going into the final that the weekend before finals week, despite the Chemistry final being on Monday, they decided to go to the University of Virginia to party with some friends.
They had a great time there. However, with their hangovers(宿醉)and tiredness, they overslept all day Sunday and didn’t make it back to Duke until early Monday morning. Rather than taking the final then, they found professor Bonk after the final and explained to him how they missed the final. They told him they went up to the University of Virginia for the weekend and had planned to come back in time to study, but they had a flat tire on the way back and didn’t have a spare. So they were late getting back to campus.
Bonk thought this over and agreed that they could take the final the following day. The two guys, happy and relieved, studied that night and went in the next day at the time that Bonk had told them. He placed them in separate rooms and handed each of them a test booklet. He told them to begin.
They looked at the first problem which was something simple about solution(溶解). It was worth 5 points. “Cool,” they thought, “this is going to be an easy final”. They then turned the page. They were unprepared, however, for what they saw on it. The question contained only two words: (95 points) Which tire?
小題1: The two guys decided to go to the University of Virginia because ________.
A.they were afraid of the finalB.there was a party there

小題1:D 細(xì)節(jié)題。第一段第三行有提及兩名學(xué)生選擇去聚會而不復(fù)習(xí)的原因是These two friends were so confident in going into the final。所以選擇D。
小題1:D 理解推斷題。從最后考試時老師出給兩位同學(xué)的題目 Which tire?可以推測出教授其實并不相信二人找出的”輪胎壞了”的借口。故選擇D.
小題1:A 考察對文章主旨的掌握以及推測能力。由最后一段的問題可以得知兩名學(xué)生會對自己的謊言感到羞愧并向教授道歉。故選擇A。
小題1:B 題目問我們從文章中得到什么教訓(xùn)。A項做錯了事的人成不了大器。C禮貌不會讓你丟失什么。D三思而后行。對比后只有B較切合文章主題,意為誠實的人才是智者。

The idea of sailing west to reach the riches of the East Indies and the Asian mainland was much in fashion with cultured Europeans during the late fifteenth century. Learned people agreed that the earth was round: their only questions were how long and how dangerous would be a trip to reach the Orient. Christopher Columbus, the son of an unknown weaver, and himself a weaver of ambitious dreams, made his historic voyage to the New World in 1492. He didn't go to school very much, but be learned to read and write Spanish during his travels. He also taught himself Latin because all the geography books were written in Latin. Sailing with a tiny fleet of three ships, the Santa Maria and two smaller ships, the Pinta and the Nina and a crew of ninety sailors, be found the thirty-three-day crossing easier than his nearly-decade-long effort to find royal sponsors willing to support it. The trip drew not only on his own skills as an expert ship's captain, but also on his ability to plan such an expedition, obtain governmental approval and financing, and finally, demonstrate its success so that such explorations could continue. He tried for years to get King Ferdinand and Queen Isabella to supply him with ships and money. Finally they agreed, but he made more demands. He wanted to be made a knight, admiral of the Ocean Sea. He wanted to be the viceroy(總督)and governor general of all lands he would discover. Also he wanted one-tenth of everything he found of value in the new lands. The explorations that followed Columbus-those of Cabot, Verrazano, Cartier, and many others-benefited from a new maritime technology borrowed from Arab sailors and from a variety of new vessels (船,艦) such as the light-weight caravels employed by Columbus. Sailors also perfected sails and various types of riggings that gave ships added stability and greater maneuverability(可操作性)on the open seas. And when leaving sight of the coast, new navigational aids-charts, compasses, and astrolabes-permitted them to determine their position with some, though not perfect, accuracy. Columbus himself made a total of four voyages to the New World but he did not become rich as he had hoped. At the end of his life he only had a pension the king and queen had given him because he was the first to reach the New World. He spent the last few months of his life in bed because of the pain of arthritis(關(guān)). Columbus not only discovered a New World, but led the way for other explorers.
小題1:What was the dream destination of Europeans in the late fifteenth century?
A.The oriental countries.B.The East Indonesia.
C.The Old World.D.The African mainland. .
小題2:What preparations did Columbus make for his first voyage to the New World?

③He gathered a great many ships.
④He hired 90 sailors.
⑤He demonstrated his success of former far-reaching explorations.
A.①②③④⑤B.①②④C.①④⑤D.②④⑤
小題3:We can learn from the passage that ________.
A.Christopher Columbus was an ambitious explorer
B.he was a geologist with ambitious dreams
C.Columbus became extremely wealthy after making a total of four voyages
D.he was an unsuccessful canvasser(游說者)
小題4:What equipment aided the sailors in locating relatively more accurately?
A.A variety of new vessels.B.The light-weighted caravels.

When my father was dying, I traveled a thousand miles from home to be with him in his last days. It was far more heartbreaking than I’d expected, one of the most difficult and painful times in my life. After he passed away I stayed alone in his apartment. There were so many things to deal with. It all seemed endless. I was lonely. I hated the silence of the apartment.
But one evening the silence was broken: I heard crying outside. I opened the door to find a little cat on the steps. He was thin and poor. He looked the way I felt. I brought him inside and gave him a can of fish. He ate it and then almost immediately fell sound asleep.
The next morning I checked with neighbors and learned that the cat had been abandoned by his owner who’s moved out. So the little cat was there all alone, just like I was. As I walked back to the apartment, I tried to figure out what to do with him. Having something else to take care of seemed like the very last thing I needed. But as soon as I opened the apartment door he came running and jumped into my arms. It was clear from that moment that he had no intention of going anywhere. I started calling him Willis, in honor of my father’s best friend.
From then on, things grew easier. With Willis in my lap time seemed to pass much more quickly. When the time finally came for me to return home I had to decide what to do about Willis. There was absolutely no way I would leave without him.

They were going to Fort Lauderdale — three boys and three girls — and when they boarded the bus, they were carrying sandwiches and wine in paper bags, dreaming of golden beaches and sea tides as the gray, cold spring of New York went behind them.
As the bus passed through New Jersey, they began to notice Vingo. He sat in front of them, completely in silence.
Deep into the night, outside Washington, the bus pulled into Howard Johnson’s, and everybody got off except Vingo. The young people began to wonder about him. When they went back to the bus, one of the girls sat beside him and introduced herself.
“Want some wine?” she said. He smiled and took a swig from the bottle. He thanked her and became silent again. After a while, she went back to the others, and Vingo nodded in sleep.
In the morning, they awoke outside another Howard Johnson’s, and this time Vingo went in. The girl insisted that he join them. He ordered black coffee and some cookies as the young people talked about sleeping on beaches. When they returned to the bus, the girl sat with Vingo again, and after a while, slowly and painfully, he began to tell his story. He had been in prison in New York for the past four years, and now he was going home.
“Are you married?”
“I don’t know.”
“You don’t know?” she said.
“Well, when I was in prison I wrote to my wife,” he said, “I told her that I was going to be away for a long time, and that if she couldn’t stand it, if the kids kept asking questions, and if it hurt her too much, well, she could jus forget me. I’d understand. Get a new man, I said — she’s a wonderful woman. I told her she didn’t have to write me. And she didn’t. Not for three and a half years.”
“And you’re going home now, not knowing?”
“Yeah. Well, last week, when I was sure the parole (假釋) was coming through, I wrote her again. We used to live in Brunswick, just before Jacksonville, and there’s a big oak (橡樹) just as you come into town. I told her that if she didn’t have a new man and if she’d take me back, she should put a yellow handkerchief on the tree, and I’d get off and come home. If she didn’t want me, forget it — no handkerchief and I’d go on through.”
“Wow,” the girl exclaimed, “Wow.”
She told the others, and soon all of them were in it, looking at the pictures Vingo showed them of his wife and three children.
Now they were 20 miles from Brunswick, and the young people took over window seats on the right side, waiting for the approach of the great oak. Vingo stopped looking, tightening his face, as if protecting himself against still another disappointment.
Then Brunswick was ten miles, and then five. Then, suddenly, all of the young people were up out of their seats, shouting and crying.
Vingo sat there astonished, looking at the oak. It was covered with yellow handkerchiefs — 20 of them, 30 of them, maybe hundreds, flying in the wind. As the young people shouted, Vingo slowly rose from his seat and made his way to the front of the bus to go home.
小題1:At the beginning of the story, the young boys and girls ______.
A.showed a great interest in VingoB.didn’t notice Vingo at all
C.wanted to offer help to Vingo D.didn’t like Vingo at all
小題2:The underlined part “Howard Johnson’s” is most probably a(n) ______.
A.bus stationB.a(chǎn)partmentC.hospital D.restaurant
小題3:How did Vingo feel on the way home?

For eighty four days old Santiago had not caught a single fish. At first a young boy, Manolin, had shared his bad fortune, but after the fortieth luckless day the boy’s father told his son to go in another boat. From that time on, Santiago worked alone. The boy loved the old fisherman and  always helped him with money and food. Usually, they would talk about the fish they had taken in luckier times or about American baseball after supper, while at night, alone in his cottage, Santiago dreamed of lions on the beaches of Africa, where he had gone years before. He no longer dreamed of his dead wife.
On the eighty-fifth day, Santiago set off to fish before dawn. Two of his baits(餌) were fresh tunas(金槍魚) the boy had given him, as well as sardines(沙丁魚) to cover his hooks. Then he set his lines which went straight down into deep dark water.
As the sun rose he saw other boats in toward shore. A bird showed him where dolphin were chasing some flying fish. This time Santiago saw tuna jumping in the sunlight. A small one took the hook on his line. Pulling the fish aboard, the old man thought it a good fortune.
Toward noon a marlin, a common fish in the sea, started eating the bait which was one hundred meters down. Gently the old man played the fish, a big one, as he knew from the weight on the line. At last he struck to settle the hook. The fish did not come out of the surface. Instead, it began to pull the boat to the northwest. The old man followed it. Although he was alone and no longer strong, he had his skill and knew many tricks. He waited patiently for the fish to be tired .
It was cold after the sunset. When something took one of his remaining baits, he cut the line with his knife. Once the marlin leaned suddenly, pulling Santiago forward on his face and cutting his cheek. By dawn his left hand was cramped(抽筋的). The fish had headed northward; there was no land in sight. Hungry, he cut pieces from the tuna and chewed them slowly.
That morning the fish jumped. Seeing it, Santiago knew he had hooked the biggest marlin he had ever seen. Then the fish went down and turned toward the east. Santiago drank a little water from the bottle during the hot afternoon.
Close to nightfall a dolphin took the small hook he had rebaited. He lifted it aboard, careful. After he had rested, he cut meat from the dolphin and kept also the two flying fish he found in its stomach. That night he slept. He awoke to feel the line running through his fingers as the fish jumped. Feeding line slowly, he tried to tire the marlin. After the fish slowed its run, he washed his cut hands in sea water and ate one of the flying fish. At sunrise the marlin began to circle. Faint, he worked to bring the big fish nearer with each turn. Almost exhausted, he finally drew his big fish alongside and drove in the harpoon(魚叉). The fish was two feet longer than the boat. No fish like it had ever been seen in Havana harbor.
An hour later, he sighted the first shark, a fierce Mako, and it came in fast to chase after the dead marlin. The old man struck the shark with his harpoon. The Mako rolled and sank, carrying the harpoon with it and leaving the marlin bloody. He knew the smell would spread. Watching, he saw two sharks closing in. He struck at one with his knife and watched it sliding down into deep water. The other he killed while it tore at the flesh of the marlin. When the third appeared, he thrust(刺) it with the knife. The other sharks came at sunset. At first he tried to beat them with the tiller(舵柄) from the boat, but his hands were bleeding and there were too many in the sea. In the darkness, as he steered toward the harbor of Havana, he heard them hitting the boat again and again. But the old man thought only of his steering and his great tiredness. He had gone out too far and the sharks had beaten him. He knew they would leave him nothing but the stripped skeleton of the big marlin.
All lights were out when he sailed into the little harbor and beached his boat. He could just make out the white backbone and the upstanding tail of the fish. Once he fell under their weight and lay patiently until he could gather his strength to go on. In his cottage he fell on his bed and went to sleep.
小題1:The above story is adapted from __________.
A.Treasure Island B.The Adventures Of Tom Sawyer
C.The Old Man And The Sea D.The Son Of The Sea
小題2:Why did the man feel that he could be lucky this time?
A.Because a small tuna took the hook on his line.
B.Because he dreamed about the American lions.

A.The boy had mercy on Santiago.
B.The boy often shared his stories with Santiago.
C.The boy showed his great concerns to Santiago.
D.The boy was Santiago’s adopted son.

If you were to walk up to Arthur Bonnet and say, "Hey, Butterfly Man," his face would break into a smile. The title suits him. And he loves it.
Arthur Bonnet works with the Palos Verdes blue butterfly, once thought to have died out. Today the butterfly is coming back thanks to him. But years ago if you'd told him this was what he'd be doing someday, he would have laughed, "You're crazy." As a boy, he used to be a little tough guy on the streets". At age thirteen, he was caught by police stealing. At eighteen, he landed in prison for shooting a man.
"I knew it had hurt my mom," Bonner said after he got out of prison. "So I told myself I would not put my mom through that pain again."
One day he met Professor Mattoni, who was working to rebuild the habitat for an endangered butterfly called E1 Segundo blue.
"I saw the sign 'Butterfly Habitat' and asked, 'How can you have a habitat when the butterflies can just fly away?'" Bonner recalls. "Dr. Mattoni laughed and handed me a magnifying glass (放大鏡) , "Look at the leaves. ' I could see all these caterpillars (蝴蝶的幼蟲) on the plant. Dr Mattoni explained, 'Without the plant, there are no butterflies. '"
Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly that needed help. That was how he met the Palos Verdes blue. Since then he's been working for four years to help bring the butterfly back. He grows astragals, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.
The butterfly's population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonnet, he earned something more: he turned his life around.
For six years now Bonnet has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.
小題1:When he was young, Arthur Bonner
A.broke the law and ended up in prison
B.was fond of shooting and hurt his morn
C.often offered necessary help to other people
D.often caught butterflies and took them home
小題2:Bonner came to know the Palos Verdes blue after he ______.
A.found the butterfly had died out
B.won many prizes from his professor
C.met Dr. Mattoni, a professor of biology
D.collected butterflies and put them into a lab
小題3: From the last sentence of the text, we learn that raising butterflies has ______
A.made Bonner famousB.changed Bonner's life
C.brought Bonner wealthD.enriched Bonner's knowledge
小題4: Which of the following would be the best title for the text?
A.A Promise to MornB.A Man Saved by Butterflies
C.A Story of ButterfliesD.A Job Offered by Dr. Mattoni
