Except for the crackling(爆裂声)of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island. With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn.The nine-year-old raced back into the house and upstairs to his mother’s room. He found it impossible to waked her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and , as a fireman said later, “acted with all the self-control of a trained adult.”On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor? Grasping firmly a ball of string(线绳) from the garage, Glenn raced back into the house and dashed upstairs to his mother’s room. Tying one end of the string to her hand,he ran back, laying out the string as he went, through the hall and back out into the garden.Minutes later he was telli ng fire chief John Coughlan: “The string will lead you to mother.” Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor.【小题1】Why did Glenn run downstairs first?A.He wanted to find out what was happening.B.He was worri ed about his mother’s safety.C.He wanted to save his sister and brother.D.He went to see if his father had come back from work.【小题2】How did Glenn help the firemen to save his mother?A.By throwing water all over her and her bed.B.By carrying her to safety with his brother.C.By push ing and pulling at her.D.By tying a string to her hand.【小题3】What did Glenn do to protect himself?A.He put a wet cloth around his head.B.He threw water all over himself.C.He hid himself in the bathroom.D.He rushed out to the lawn.【小题4】Glenn saved his family because___________.A.his father had taught him to do so on the phoneB.he had learned something about first aidC.he had dealt with the emergency calmly and wiselyD.he had followed his mother’s instruction8."We can not afford limited progress.

I hope not! So, why would an artist paint the sky this way? Perhaps I can answer that with another question. When you’re happy, why do you sing instead of speaking? Or when you’re in love, why do you speak of roses and honey? When we do these things, we, too areartists. We’re using something that goes beyond a mere scientific descript ion in order to communicate our feelings more powerfully than straightforward words can. So consider for a moment that Van Gogh might not have been hallucinating (产生幻觉的) on the night he painted this. Maybe he felt something so powerful that he had to go beyond the familiar to express it.I hope I’m reminding you of something you already know as I describe the experience of being outside at night under a crystal clear sky that makes everything seem clean and refreshing. So you look up. And suddenly you see t he sky that you’ve seldom seen before. It’s not just the same old dark night sky tonight. Instead, the blackness is a deep, rich blue that is more bottomless than any ocean. The stars are not spots of light but brilliant, magical diamonds that dance like tiny angels. In just this special moment, the sky is somehow alive, and it seems to speak to you silently about the meaning of infinity (无限).Now look at the painting again. Can you see something of what makes this such a famous and well-loved image? But th ere’s more here than that. Van Gogh painted this while he was quite struck down by a mental disease. It is natural to imagine that he frequently battled the fear that he would never escape his prison to true freedom. It is natural for us to imagine this because each of us has faced our own personal prison, whether it be disease, the loss of a loved one, serious financial problems … In such moments it is tempting to give up to despair (绝望) and collapse in hopelessness. Looking at this painting, I imagine Van Gogh in just such a moment of despair, when he is struck by the memory of one of those amazing night skies. He recalls the sense that he is not alone, that there is a living, infinite world with rich colorful creatures and scenes all around.And so the sky flows across the canvas (画布) full of vitality (活力) and power. The stars don’t just sparkle; they explode. Looking closer, we notice that the earth itself seems to respond to the movement in the sky, forming its own living waves in the mountain and rolling trees. In the sleepy village, the windows of the houses glow (发光) with the same light that brightens the universe. The giant trees at the left seem to capture the joy by stretching upwards toward the sky.What a tremendous message of hope there is in this masterpiece! Even if our troubles persist, the world around us assures us that life is worth living. That’s what the angels sing about. Doesn’t it make you want to sing, too?【小题1】Looking at the painting Starry Night, we can see all the followingexcept________.A.The singing angelsB.the giant treesC.the sleepy villageD.the sparkling stars【小题2】Van Gogh does NOT describe a feeling of ______ through the Starry Night. A.happinessB.vitalityC.powerD.despair【小题3】The underlined word “prison” in the 3rd paragraph probably means ______. A.trouble in one’s lifeB.mental illnessC.control from the authorityD.a place where criminals are kept【小题4】What is the main purpose of this passage?A.To explain how Van Gogh painted the Starry Night.B.To tell us how to appreciate the Starry Night.C.To prove Van Gogh was in a hallucinating state of mind while painting the picture. D.To show us the beauty of the sky on a starry night.15.it tastes just chickenAway from home, eating is more than just a way to keep your stomach full.It is a language all its own, and no words can say, "Glad to meet you ...glad to be doing business with you ..." quite like sharing a meal offered by your host.Clearly, mealtime is not the time for you to say, "Thanks, but no thanks." Acceptance of the food on your plate means acceptance of host, country, and company.So, no matter how difficult it may be to swallow, swallow.Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere."Often, the food offered represents proudly your host country's eating culture.What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it.After all, an oyster has remarkably the same look as a sheep's eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat.By the way, in Saudi Arabia sheep's eyes are a famous dish and in parts of China it's bear's paw soup.Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites.It helps, though, to slice any item very thin.This way, you minimize the taste and the reminder of where it came from.Or, " Swallow it quickly, " as one traveler recommends."I still can't tell you what sheep's eyeballs taste like." As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true.Even when the "it" is really rat or snake.Another useful piece of advice is not knowing what you are eating.What's for dinner? Don't ask. Avoid glancing into the kitchen or looking at English-language menus.Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup.【小题1】The purpose of the article is to ____.A.introduce unfamiliar foodB.share the writer's personal experiencesC.suggest ways to overcome a cultural barrierD.advise on how to politely refuse to eat foreign food【小题2】According to the writer, people hesitate at strange food mainly due to____.A.the way it looksB.safety worriesC.lack of information about itD.the unfamiliar atmosphere【小题3】From the article we can infer that ____.A.an American may feel comfortable with sirloinB.one should refuse strange food after a few bitesC.English-language menus are not always dependableD.one needs a cast-iron stomach to travel in other cultures【小题4】One may say "It tastes just like chicken." when ____.A.showing respect for chicken-loving nationsB.greeting people with different dieting habitsC.evaluating chefs at an international food festivalD.getting someone to try a visually unpleasant meal16.——Will you require anything else?——Yes, I like a whisky.A.willB.shallC.shouldD.might17.Catherine came home happily, which suggested that she the final exam. A.had passedB.passC.would passD.should pass18.David和几位同学正在进行一项“企业家成功秘诀调查”。
