单选题In the late summer of 2005, the remarkable flooding brought by Hurricane Katrina, which caused more than ＄ 200 billion in losses, was the worst natural disaster in U.S. history. However, even in typical years, flooding causes billions of dollars in damage and threatens lives and property in every State. Natural processes, such as hurricanes and weather systems can cause floods. Failure of levees and dams and inadequate drainage in urban areas can also result in flooding. On average, floods kill about 140 people each year and cause ＄ 6 billion in property damage. Although loss of life to floods during the past half-century has declined, mostly because of improved warning systems, economic losses have continued to rise due to increased urbanization and coastal development. Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or levees break. Flooding may be only a few inches of water or it may cover a house to the rooftop. Floods that happen very quickly are called flashfloods. Flooding is the most common of all natural hazards. It can happen in every U. S. state and territory.And here is something else for you:·Flood Watch or Flashflood Watch--Flooding may happen soon.

单选题Here"s how I want to watch the 2014 Winter Olympics. I want to go to a Web site to see any event I want, whenever I want to watch it, on whatever screen I choose. I"ll gladly pay. The technology exists to make this happen today. Yet nearly two decades after the introduction of the World Wide Web, this remains a fantasy. NBC, which broadcasted the Vancouver Olympics in the United States, wouldn"t put videos on its Web site until they had been shown on prime-time TV. So Americans had the weird experience of learning from a news report during the day that something fantastic had just happened, and then having to wait until that night"s broadcast to see it. Bloggers complained, but NBC wouldn"t give way. Its research shows that people like me, who want to watch the Olympics online, represent only 7 percent of the total audience. The other, bigger concern is: the Internet doesn"t deliver any money. Advertisers remain willing to pay big money to show their commercials on prime-time TV. But on the Internet? Not so much. So NBC clings to the old way of doing things. As it sees it, the prime-time show is the most important. To make matters worse, NBC was already expecting to lose $250 million on the 2010 Vancouver Games. Good luck persuading it to invest in a risky Web project. It"s easy to blame the network executives. But the NBC guys and their like are only doing what makes sense. They"re going where the money is. That needs to change. Yes, selling reporting of Olympic events over the Internet would drain away some of the prime-time audience, but my sense is many of the online subscribers would still watch the prime-time show. And over time, the subscription dollars could become a substantial revenue stream. Instead of viewing the Internet as a threat to prime time, the TV networks should see the Web as a way to sell even more of their product to a small but passionate subset of their audience. I"m hoping that by 2014, that will have changed.

单选题Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people's. In the same way, children learning to do all the other things they learn to do without being taught — to walk, run, climb, whistle, ride a bicycle — compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what the answer to that problem is, whether or not this is a good way of saying or doing this or not. If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine work? Our job should be to help the child when he tells us that he can't find the way to get the right answer. Let's end all this nonsense of grades, exams, and marks. Let us throw them all out, let the children learn what all educated persons must some day learn and how to measure their own understanding, and how to know what they know or do not know. Let them get on with this job in the way that seems most sensible to them, with our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learned at school and used for the rest of one's life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, "But suppose they fail to learn something essential, something they will need to get on in the world?" Don't worry! If it is essential, they will go out into the world and learn it.

单选题Finding in investigations in Britain indicate ______.

单选题Bernard Jackson is a free man today, but he has many bitter memories. Jackson spent five years in prison after a jury wrongly convicted him of raping two women. At Jackson's trial, although two witnesses testified that Jackson was with them in another location at the times of the crimes, he was convicted anyway. Why? The jury believed the testimony of the two victims, who positively identified Jackson as the man who had attacked them. The court eventually freed Jackson after the police found the man who had really committed the crimes. Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a lineup of people. They can become confused by seeing many photographs of similar faces. The number of people in the lineup, and whether it is a live lineup or a photograph, may also affect a witness' decision. People sometimes have difficulty identifying people of other races. The questions the police ask witnesses also have an effect on them. Many people believe that police officers are more reliable than ordinary people. Psychologists decided to test this idea, and they discovered that it is not true. Two psychologists showed a film of crimes to both police officers and civilians. The psychologists found no difference between the police and the civilians in correctly remembering the details of the crimes. Despite all the possibilities for inaccuracy, courts cannot exclude eyewitness testimony from a trial. American courts depend almost completely on eyewitness testimony to resolve court cases. Sometimes it is the only evidence to a crime, such as rape. Furthermore, eyewitness testimony is often correct. Although people do sometimes make mistakes, many times they really do identify individuals correctly. American courts depend on the ability of the twelve jurors, and not the judges, to determine the accuracy of the witness' testimony. It is their responsibility to decide if a certain witness could actually see, hear, and remember what occurred. In a few cases the testimony of eyewitnesses has convicted innocent people. More importantly, it has rightly convicted a larger number of guilty people; consequently, it continues to be of great value in the American judicial system.
