单选题 The earliest immigrants to North America found Indians already living there. The Indians numbered about 500,000 at that time. Their society was a primitive society, but they lived peacefully and welcomed the white strangers to the land. However, these early immigrants from Europe didn't want to share the land with the natives. They killed off many of the Indians, seized their land or pushed them off to lands farther away. Today the Indians, not more than halfa million, live in poverty and misery on the land on which they were once masters. The earliest immigrants were the Spanish, who settled in the southern part of what is now the US The next large group were the English, after the English came the French, Dutch, Irish, Germans, and other nationality groups, mostly European. Another early group to arrive were the Negroes. But they were brought in as slaves from Africa. They didn't win freedom till generations later.

单选题 A child of five is friendly, competent and obedient, although he may be bossy with other children and is sometimes sufficiently independent to call his mother names. He is still dependent on adult approval and praise, and so orientated (对……感兴趣) to the grown-up that he tells tales without seeing the other child's point of view. There is no real discussion yet fives talking together indulge in a 'collective monologue (独白)'; quarrelling with words often begins towards the end of the year. Group play is often disrupted because everyone wants to be the mother or the bride or the captain of the fire brigade. Each child has an urgent need for constantly recurring (反复的) contact with an adult in spite of all his efforts to be independent. In his unsureness he may make statements about his own cleverness and beauty, hoping that the adult will praise him: this is not conceit but a cry for reassurance. He loves to say 'Watch what I can do.' Reality and fantasy are still intermingled and this confusion may lead him to elaborate on facts.

单选题 It used to take Redwood City, California police hours to locate gunfire. Now, they have a new tool that helps them find the gunfire quickly. This new tool is called the ShotSpotter. The police began using the ShotSpotter in 1995. They wanted to cut down on gunfire in their city. One ShotSpotter covers a square mile. Eight microphones are put on the roofs of buildings. These microphones pick up gunfire noise. It only takes seven seconds to report the gunfire to the police. Then a red dot on the police map shows where the action is. The ShotSpotter really works well. It locates the gunfire within 20 to 40 feet plus or minus. Redwood City police are very happy with the ShotSpotter. They think it might have helped catch the D.C. sniper. ShotSpotters cost a lot of money. One of them sells for $200,000. Despite the cost, ShotSpotters can be a big help in fighting crime.

单选题 All the housewives who went to the new supermarket had one great ambition: to be the lucky customer who did not have to pay for her shopping. For this was what the notice just inside the entrance promised. It said: 'remember, once a week, one of our customers get free goods. This May Be Your Lucky Day!' For several weeks Mrs. Edwards hoped, like many of her friends, to be the lucky customer. Unlike her friends, she never gave up hoping. The cupboards in kitchen were full of things which she did not need. Her husband tried to advise, her against buying things but failed. She dreamed of the day when the manager of the supermarket would approach her and say, 'Madam, this is Your Lucky Day. Everything in your basket is free!' One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy any tea. She dashed back to the supermarket, got the tea and went towards the cash-desk. As she did so, she saw the manager of the supermarket approach her. 'Madam,' he said, holding out his hand, 'I want to congratulate you! You are out lucky customer and everything you have in your basket is free!'

单选题 Staff Sgt. Nicholas Lanier has entered what he calls the 'vast unknown.' A combat veteran and father to four daughters, he can't remain in the military because of a serious back injury earned in Iraq. But he can't yet accept a civilian job because he doesn't know when the military will discharge (使退伍) him. He has no clue how much the government will pay him in disability compensation related to his injury, so he can't make a future budget. He just waits. Thousands of troops are like Lanier: not fully fit to serve but in limbo (无着落) for about two years waiting to get discharged under a new system that was supposed to be more efficient than its predecessor. And the delays are not only affecting service members, but the military's readiness as well. New troops can't enlist until others are discharged. The government determines the pay and benefits given to wounded, sick or injured troops for their military service. Under the old system, a medical board would determine their level of military compensation and the service member would be discharged. Then the veteran essentially would have to go through the process again with the Veterans Affairs Department to determine benefits. Under the new system, which started in 2007 and will be completely rolled out at military bases nationwide by the end of September, the service member essentially goes through both disability evaluation systems at the same time before leaving the military. But the new, supposedly streamlined, system is still such a cumbersome process that it's leaving many service members in limbo, they say.

单选题 I receive many letters from children and can't answer them all—there wouldn't be enough time in a day. I'll try to answer some of the questions that are commonly asked. Where did I get the idea for Stuart Little and for Charlotte's Web? Well, many years ago, I went to bed one night in a railway sleeping car, and during the night I dreamed about a tiny boy who acted rather like a mouse. That's how the story of Stuart Little got started. As for Charlotte's Web, I like animals and my farm is a very pleasant place to be—at all hours. One day, when I was on my way to feed the pig, I began feeling sorry for the pig because, like most pigs, he was going to die. This made me sad. So I started thinking of ways to save his life. Three years after I started writing it, it was published. (I am not a fast worker, as you can see.) Sometimes I'm asked when I started to write, and what made me want to write. I started early—as soon as I could spell. Children often find pleasure through trying to set their thoughts down on paper, either in words or in pictures. I was not good at drawing, so I used words instead. As I grew older, I found that writing could be a way of earning a living. Well, here is the answer to the last question. No, they are imaginary (虚构的) tales. In real life, a family doesn't have a child who looks like a mouse and a spider doesn't write words in her web. Although my stories are imaginary, I like to think that there is some truth in them, too—truth about the way people and animals feel, think and act.
