In a natural disaster—a hurricane, flood, volcanic eruption, or other catastrophes—minutes and even seconds of warning can make the difference between life and death．Because of this, scientists are working to use the latest technological advances to predict when and where disasters will happen．They are also studying how best to analyze and communicate this information once it is obtained．
On September 29, 1998, Hurricane Georges made landfall in Biloxi, Mississippi, after damaging Haiti, the Dominican Republic, Puerto Rico, and several islands of the Caribbean badly with torrential rains and winds up to 160 km per hour．Few people lost their lives along the Gulf Coast of the United States, although hundreds died in the Caribbean．
This was a very different outcome from 1900, when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston, Texas, killing at least 6,000 people．
Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century——residents of Galveston had no advance warning that a storm was approaching, while residents of Biloxi had been warned days in advance, allowing for extensive safety precautions（预防）．
At the same time that people in Biloxi were thankful for the advance warning, some residents of New Orleans, Louisiana were less satisfied．A day before Georges made landfall, forecasters were predicting that the hurricane had a good chance of striking New Orleans．Because much of New Orleans lies below sea level, the city is at risk for flooding．Emergency management officials must begin evacuations（疏散）well before a storm strikes．But evacuation costs money: businesses close, tourists leave, and citizens take precautionary measures．The mayor of New Orleans estimated that his city' s preparations for Georges cost more than 50 million．After Georges missed New Orleans, some residents questioned the value of the hurricane forecasts in the face of such high costs．
The different views on the early warnings for Hurricane Georges show some of the complexities related to predicting disasters．Disaster prediction is a process of providing scientific information to the government officials and other decision makers who must respond to those predictions．
【小题1】What is the purpose of disaster prediction according to the passage?

第三部分：阅读理解（共12小题；每小题2分，满分24分）
请认真阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
Few people realize that there is a big difference between formal English and informal English. Formal English is used for most writing, and often in public speaking and formal meetings. It pays close attention to grammar rules, because if we use proper grammar, our meaning is often more precise. Also, on important occasions, we do not want to appear uneducated or to offend (冒犯) others, so we are very careful about how we speak. Informal English is used in speaking or writing to our friends and family. It often does not pay such close attention to grammar rules, because when we speak or write to them, we want our words to flow quickly. Also, with our friends and family, we are usually not so worried about appearing uneducated or about offending them by how we write or speak.
A big difference between formal and informal English is the use of contractions. A contraction is where we make a word shorter or where we put two words together and take away some of the letters. For example, instead of saying “do not”, many people say “don’t”. Using contractions in our speech is fine because it sounds natural, especially when we speak to our friends. In formal writing, however, contractions are usually avoided because people might think that you have made a mistake, or that you do not know proper grammar.
In the same way we might make words shorter, in informal English we often make sentences shorter as well. For example, if someone asks you your name, you will likely answer with one word: your first name. However, in formal English we usually use complete sentences. For example, we might write “My name is John”. In most speaking, we may not need to use every word in a sentence because the person we are speaking to will probably still understand us. In most writing, however, every word in a sentence must be written out in order to make sure that we can be understood.
56. When we use formal English, _______.
A. we will offend others 
B. we will appear educated on important occasions
C. we needn’t pay more attention to grammar rules
D. we can express ourselves more directly and more quickly
57. What’s the meaning of the underlined word “precise”?
A. simple                    B. direct                     C. puzzling                 D. clear
58. Contractions are best used when we are _______.
A. speaking at a formal meeting                        B. speaking to our friends
C. speaking in public                                              D. writing an application (申请) letter
59. In speaking, we do not always use complete sentences because ______.
A. we do not care about grammar                    B. we do not want to sound stupid
C. we can still be understood                              D. we don’t want to waste time

Australian Flag Designs by Readers of the Sun-Herald
We received dozens of responses after inviting readers to send in their designs for a new flag. The designs we received include:
James Anthony, Drummoyne
James reduces the Union Jack down in size and changes its shape to become a reminder of the British tradition rather than canceling it altogether. At the same time he suggests enlarging the stars of the Southern Cross. His design attempts to use the best of both worlds in a newly designed flag.
As he says, “the British part of the Australian Flag is too big and the Australian bits are too small. When you make the stars bigger the Australian flag can look impressive.”
Joe Bollen, Turranmurra
Joe’s flag has the main elements of a risen sun, white horizon(地平线), red earth at the base and the Southern Cross. He intends to make the risen sun a special Australian symbol on the flag. He believes it represents life. The Southern Cross shows that we live in the Southern Hemisphere. (半球)
Maria Ieraci, Sydney
Maria deleted the Union Jack but otherwise kept the flag as is with the Southern Cross and Federation Star. She says, ‘There is only one correct way to change the Australian flag” and that is “to drop the Union Jack ---- when Australia becomes a Republic”, which she hopes will be before 2010.
Ron Bennett, Sydney
Ron recommends using the Aboriginal colors but replacing their image of the sun with the map of Australia. He says, “Australia is unique being an island continent with an instantly recognizable outline at that” and “this will leave no doubt as to which country the flag belongs.”
【小题1】Which of the four designs can remind you of the past of the country?

Nuclear radiation （核辐射）has a certain mystery, partly because it cannot be detected （探测）by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being at once by killing plenty of cells in important organs(器官). Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed at once. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
【小题1】According to the passage, the danger of nuclear power lies in       .

A few years ago, Paul Gerner began to gather a group of architects in Las Vegas to ask them what it would take to design a public school that used 50 percent less energy, cost much less to build and obviously improved student learning. “I think half of them fell off their chairs,” Gerner says.
Gerner manages school facilities（设施）for Clark County, Nevada, a district roughly the size of Massachusetts. By 2018, 143,000 additional students will enter the already crowded public-education system. Gerner needs 73 new schools to house them. Four architecture teams have nearly finished designing primary school prototypes（样品）; they plan to construct their schools starting in 2009. The district will then assess how well the schools perform, and three winners will copy those designs in 50 to 70 new buildings.
Green schools are appearing all over, but in Clark County, which stands out for its vastness, such aggressive targets are difficult because design requirements like more natural light for students go against the realities of a desert climate. “One of the biggest challenges is getting the right site orientation（朝向）,” Mark McGinty, a director at SH Architecture, says. His firm recently completed a high school in Las Vegas. “You have the same building, same set of windows, but if its orientation is incorrect and it faces the sun, it will be really expensive to cool.”
Surprisingly, the man responsible for one of the most progressive green-design competition has doubts about ideas of eco-friendly buildings. “I don’t believe in the new green religion,” Gerner says. “Some of the building technologies that you get are impractical. I’m interested in those that work.” But he wouldn’t mind if some green features inspire students. He says he hopes to set up green energy systems that allow them to learn about the process of harvesting wind and solar power. “You never know what’s going to start the interest of a child to study math and science,” he says.
45. How did the architects react to Gerner’s design requirements?
A. They lost balance in excitement.                  B. They showed strong disbelief.
C. They expressed little interest.                       D. They burst into cheers.
46. Which order of steps is followed in carrying out the project?
A. Assessment — Prototype — Design — Construction.
B. Assessment — Design — Prototype — Construction.
C. Design — Assessment — Prototype — Construction.
D. Design — Prototype — Assessment — Construction.
47. What makes it difficult to build green schools in Clark County?
A. The large size.                                           B. Limited facilities.
C. The desert climate.                                      D. Poor natural resources.
48. What does Gerner think of the ideas of green schools?
A. They are questionable.                                 B. They are out of date.
C. They are advanced.                                      D. They are practical.
