What shall I bring you? " Hindley named a fiddle (a kind of violin), and then he asked Cathy. She was hardly six years old, but she could ride any horse in the stable. She chose a whip(鞭子).He did not forget me; He promised to bring me a pocketful of apples and pears. Then he set off.The three days of his absence seemed a long while to us all. Mrs. Earnshaw expected him bysupper-time on the third evening. She put off the meal hour after hour. There were no signs of hiscoming, however. About eleven o'clock the door opened and in stepped the master. He threwhimself into a chair, laughing and groaning, and told them all to stand off, for he was nearly killed.He would never again have another such walk for whatever reasons.Opening his great coat, which he held bundled up in his arms, he said: "See here, wife. I wasnever so beaten with anything in my life. But you must take it as a gift of God though it's as darkalmost as if it came from the devil."We crowded round him. And over Miss Cathy's head, I had a look at a dirty, ragged, black-haired child-big enough both to walk and talk-yet, when it was set on its feet, it only stared round, and repeated over and over again some strange words that nobody could understand.I was frightened,and Mrs. Earnshaw was ready to throw it out of doors. She did get angry, asking why he should have brought that gipsy child into the house when they had their own kids to feed and look after? What he meant to do with it?The master tried to explain the matter though he was really half dead with tiredness. All that I could make out, among her scolding, was a story of his seeing it starving, and homeless, and almost dumb (哑的) in the streets of Liverpool where he picked it up and inquired for its owner. But not a person knew to whom it belonged. He said that as both his money and time was limited, he thought it better to take it home with him at once than run into vain expenses there. Anyway he was determined he would not leave it as he found it.Well, finally Mrs. Earnshaw calmed down, and Mr. Earnshaw told me to wash it, give it clean things, and let it sleep with the children.Hindley and Cathy then began searching their father's pockets for the presents he had promised them. But when Hindley drew out what had been a fiddle, crushed (压坏) to pieces in the great coat,he cried loudly. And Cathy, when she learned her father had lost her whip in attending on the stranger,showed her feeling by spitting at the gipsy child, earning herself a sound blow from Mr. Earnshaw to teach her cleaner manners.(Adapted from Wuthering Heights by Emily Bronte)24. When did Mr. Earnshaw return home from Liverpool?A. By supper time.B. Not until it was nearly midnight.C. When it was getting dark.D. An hour after the meal time.25.What does "A Gift of God" refer to ?A. A fiidle and a whipB. A pocketful of apples and pears.C. His experience in the journey.D.The gipsy child.D. he couldn't leave the starving child without anyone caring for it.26. It can be inferred from the passage that .A. Mr.Earnshaw felt so guilty towards Cathy that he offered her another clearner gift.B. Hindley was good-mannered even if he didn't get his present.C. Mr. Earnshaw insisted on bringing the child back regardless of his financial burden.D. Mrs. Earnshaw disagreed to keep the gipsy child in spite of everything.CWhat is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is theapplication of the machines, products and systems of knowledge that scientists and technologistsdevelop. The second is the application of the special methods of thought and action that scientistsuse in their work.What are these special methods of thinking and acting? First of all, it seems that a successfulscientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationshipseven if the data available seem to be unconnected.Moreover, he thinks he can improve the existingconditions and enjoys trying to solve the problems which this involves.He is a good observer, accurate, patient and objective and uses the facts he observes to thefullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).He does not accept statements which are not based on the most complete evidence available.He rejects authority as the only basis for truth.Scientists always check statements and make experiments carefully and objectively.Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete.Furthermore, he needs imagination if he wants to guess how processes work and how events take place.These seem to be some of the ways in which a successful scientist or technologist thinks andacts.27. Which of the following statements about a curious scientist is TRUE?A. He focuses on the problems that have no reasonable explanations.B. He makes efforts to investigate potential connections.C. He is interested in condition-improvig and problem-solving.D. He rejects authority as he believes himself to be the only reliable one.28. According to the passage, a successful scientist would .A. easily appreciate others' research work.B. easily believe in unchecked statements.C. always accept authority as the only basis for truthD. always use evidence from observation to the fullest.29. Which word can be used to describe the author's attitude that a good scientist holds towards the scientific research?A. Objective and careful.B.curious and casualC. cautious and arrogant.D.subjective and down-to-earth.30. What does the passage mainly discuss?A. Key to a successful scientist.B. Scientists' ways of thinking and acting.C. Progress in modern science.D. Application of modern technology.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
