B
Events such as hurricanes, earthquakes, floods, volcanic eruptions, and tornadoes are all natural disasters. They are mostly related to the weather. Some are predictable ----like a hurricane. Some, like an earthquake, surprise us. It is necessary for us to learn about them, so we can be prepared!
Flooding happens during heavy rains, when rivers overflow, when ocean waves come onshore, when snow melts too fast or when dams or banks break. Flooding is the most common of all natural disasters.
Hurricanes are severe tropical storms that form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation(蒸發(fā)) from the sea water increases their power.
Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars.
Tornadoes are nature’s most violent storms. Tornadoes must always be taken seriously. Tornadoes can be very dangerous ---- sometimes even deadly. They come from powerful thunderstorms and appear as moving. Tornado winds can reach 300 miles per hour. They cause damage when they land the ground. They can damage an area one mile wide and 50 miles long.
While thunder won't hurt you ----lightning will! So it's important to pay attention when you hear thunder. Thunderstorms happen mostly in summer and every thunderstorm has lightning. Lightning can strike people and buildings, which is very dangerous.
Thunderstorms affect small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes.
A volcano is a mountain with a large opening at the top through which melting rock, steam, gases escape from time to time with violent force from inside the earth. When pressure increases, eruptions occur. Gases and rock shoot up through the opening fill the air with small pieces. Eruptions can cause lava flows, hot ash flows, mudslides, falling ash and floods, which is likely to knock down entire forests, cause floods and earthquakes. Fresh volcanic ash can cause damage to the lungs of older people, babies and people with respiratory problems.
64. From the passage, we know that ______.
A. all natural disasters can be predicted 
B. all natural disasters are connected with the weather.
C. human beings can do nothing with natural disasters
D. the more we know about natural disasters, the less we will suffer.
65. Which of the following is NOT true according to the passage?
A. Flooding is the most common natural disaster. 
B. Hurricanes and tornadoes can land the ground and cause damage.
C. Thunder can strike people and buildings.          
D. Fresh volcanic ash can cause illnesses.

D
An altimeter(高度計(jì)) is an instrument used in an airplane to tell the pilot how high he is flying. The altimeter used in most airplanes is a kind of barometer(氣壓計(jì)), which, like barometer found in ordinary homes, is a measuring instrument for air pressure. The weight of the atmosphere presses downwards everywhere. At sea level this pressure is more than 14 pounds on every square inch of the surface. The higher you go into the air, the lower the air pressure is. An altimeter measures this air pressure to show the altitude of the airplane, or, how high it is above sea level.
But the altimeter does not show how high the plane is above the ground. A plane might be flying at an altitude of 15,000 feet, but it would be only a thousand feet or so above the ground if the land in that area happened to be 14,000 feet above sea level. The pilot adjusts his altimeter to the actual sea-level pressure before leaving the airport and then corrects it in flight by new information given to him by radio. He flies high enough to be above any mountain he may pass on his course .The barometer altimeter is correct within about 300 feet.
Another kind of altimeter, the radio altimeter, makes use of radio reflection. It calculates the height of the flying plane by sending out electrical signals to the surface below and measuring the time required for them to bounce back(反彈). It is correct within 15 feet over water, but is not reliable over land. Big planes usually have both kinds of altimeter.
67. Which of the following diagrams gives the correct relationship between altimeters and barometers? (a----altimeters, b----barometers)

68. The following drawing shows a plane flying over a mountain. Which of the heights given in the drawing is given by the barometer altimeter in the plane at this moment?

69. Suppose a plane using a radio altimeter is flying 10,000 meters above highland which is 4,000 meters above sea level. What reading will be given by the altimeter?
A.10,000meters.   B. 4,000meters.    C.14,000meters.    D. 6,000 meters.
70. Suppose a plane using both kinds of altimeters is flying over a mountainous area where the land rises and falls very abruptly (迅速地). The pilot keeps his plane steady at the same height. What kind of reading will you get on each of the altimeters?
A. The readings on both altimeters will remain steady.
B. The readings on both altimeters will rise and fall abruptly.
C. The readings on the barometer altimeter will rise and fall abruptly, while that on the radio altimeter will remain steady.
D. The readings on the radio altimeter will rise and fall abruptly, while that on the barometer altimeter will remain steady.

A
A Subway Superhero
Wesley Autrey can't fly, but he is still being called a real-life Superman! Last week, the brave 50-year-old rescued Cameron Hollopeter, 20, from being hit by a train. The train was entering a subway station in New York City. The young man had fallen from the station's platform and onto the train tracks a few feet below.
Autrey, a construction worker and Navy veteran(老兵), was with his two young daughters when he saw Hollopeter fall. Autrey made a quick decision and jumped onto the tracks. He then rolled himself and Hollopeter into a gap, or opening, between the rails. Autrey used his own body to protect the young man.
Five of the train’s cars passed over the two before stopping completely. The two men were both unharmed. Hollopeter’s stepmother, Rachel Hollopeter, called Autrey an “angel”. Autrey visited the New York Film Academy student in the hospital on Wednesday.
For his bravery, Autrey was given a hero's welcome at City Hall. New York City Mayor Michael Bloomberg presented Autrey with the Bronze Medallion (銅獎(jiǎng)?wù)拢? It is the city'’s highest award for achievements by its citizens. Mayor Bloomberg called Audrey “ a great man-a man who makes us all proud to be New Yorkers."
After the ceremony at City Hall, a limousine (豪華轎車(chē))took Autrey to a meeting with multimillionaire businessman Donald Trump. Trump awarded Autrey with $ 10,000. The heroic father also received $ 5,000 from the New York Film Academy, a trip to Disney World, and one year of free sub way rides.
Even after all this attention; Autrey still doesn't see himself as a Superman.” I did it out of a split-second reaction," Autrey said on CBS' The Early Show. "And if I had to do it again, I probably would."

C
Many Older Doctors Plan to Give up Their Practice
The results of a new survey indicate that 48 percent of physicians between 50 and 65 years of age are planning to reduce or end their clinical practice in the next l to 3 years. The findings also suggest that many older physicians believe that their younger counterparts do not have the work ethic they do.
The survey, which was conducted by Merritt Hawkins＆Associates, a Texas-based physician search and consulting firm, suggests that many older physicians are simply unhappy with the changes that have taken place in medicine over the years.
"When Baby Boom doctors entered medicine, they had control over how they practiced and the fee they charged. But the rules changed on them in mid-stream and now many are looking for a ticket out," Mark Smith, executive vice president of Merritt Hawkins＆Associates, said in a statement.   "Our study is the only one I am aware of that examines the career plans of physicians in the 50-to-65 age group." This age group represents more than one-third of all physicians in the U. S. If they stop working in the coming years, it will have a "significant impact" on the overall supply of physicians, Smith told Reuters Health.
The results of the survey, which included 1,170 respondents（調(diào)查對(duì)象）, show that 24 percent of older physicians are planning to leave clinical practice all together in the next 1 to 3 years. Specifically, 14 percent said they were planning on retiring, 7 percent said they were looking for a medical job in a non-patient care setting, and 3 percent said they were seeking a job in a non-medical field.
For those physicians not leaving clinical practice, many said they would make changes to reduce the number of patients they treat. For instance, 12 percent said they would begin working part-time, 8 percent said they planned to stop taking new patients or markedly reduce their patient load, and 4 percent expressed a desire to work on a temporary basis.
When asked about the work ethic of physicians entering practice today, 68 percent of the respondents said that these younger doctors are not as dedicated or as hard working as physicians who entered practice 20 t0 30 years ago. Fifty-seven percent of older physicians said they would not recommend medicine as a career to their own children. Similarly, 44 percent said they would not select medicine as a career if they were starting out today.   
"The most ominous（不祥的）finding is that about one half of physicians surveyed plant to either abandon patient care in the next 1 to 3 years, or significantly reduce the number of patients they see," Smith said. "The U. S. already is facing a widespread shortage of physicians. Should older, ‘workhorse' physicians choose to give up patient care, access to medical services will be further restricted."
66. Which is NOT true of physicians in the 50-to-65 age group in the U. S.?
A. They are mostly baby boomers.
B. They have nothing to complain about.
C. Many of them plan to gradually stop their practice.
D. They account for over one-third of all physicians in the country.  
67. The survey was focused on         .
A. the living conditions of older physicians in the U. S.
B. the career plans of older physicians in the U. S.
C. the retirement plans of older physicians in the U. S.
D. the achievements of older physicians in the U.S.
68. Many older physicians in the U. S. view the work ethic of their younger
counterparts        .
A. with appreciation    B. with disapproval    C. with jealous        D. with indifference
69. In the eyes of many older physicians, medicine         .
A. comes first in their choice of a career for their children
B. remains their lifelong pursuit
C. is not as good a career as it used to be
D. is more demanding than it used to be
70. If many older physicians stop working in the coming years, Americans will have         .
A. even less access to medical services         B. even better patient care
C. a shortage of younger physicians             D. more job opportunities

E
Everyone has heard of the San Andreas fault (斷層), which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri?
Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur （硫磺）to filter upward.
The Mississippi River itself completely changed character, developing sudden rapids and whirlpools. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C.
Scientists now know that America’s two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the movement of these two masses suddenly lurches (傾斜) forward.
The New Madrid fault, on the other hand, is a vertical fault; a some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions trigger (觸發(fā)) earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern lllinois.
Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but the scientists say have no method of predicting when a large earthquake will occur.
72. This passage is mainly about__________.
A. the New Madrid fault in Missouri
B. the San Andreas and the New Madrid faults
C. the causes of faults
D. current scientific knowledge about faults
73. The New Madrid fault is__________.
A. a horizontal fault            
B. a vertical fault
C. a more serious fault than the San Andreas fault
D. responsible for forming the Mississippi River
74. We may conclude from the passage that__________.
A. it is probably as dangerous to live in Missouri as in California
B. the New Madrid fault will eventually develop a mountain range in Missouri
C. California will become an island in future
D. A big earthquake will occur to California soon
75. This passage implies that__________.
A. horizontal faults are more dangerous than vertical faults.
B. Vertical faults are more dangerous than horizontal faults
C. Earthquakes occur only around fault areas
D. California will break into pieces by an eventual earthquake

C
Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there’s whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job's pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:
1) Do you prefer working alone or with other people?
There are isolating(使孤立) jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
2) How do you handle change?
Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine.
3) Do you enjoy working with computers?
I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well.
4) What type of work environment do you enjoy? 
This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly.
5) How do you like to get paid?  
Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.
Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.

In communities north of Denver, residents are pitching in to help teachers and administrators as the Vrain school District tries to solve a $13.8 million budget shortage blamed on mismanagement. “We’re worried about our teachers and principals, and we really don’t want to lose them because of this,” one parent said. “If we can help ease their financial burden, we will.”
Teachers are grateful, but I know it may be years before the district is solvent (有綜合能力的). They feel really good about the parent support, but they realize it’s impossible for them to solve this problem.
The 22,000-student district discovered the shortage last month. “It’s extraordinary. Nobody would have imagined something happening like this at this level,” said State Treasurer Mike Coffman.
Coffman and district officials last week agreed on a state emergency plan freeing up a $9.8 million loan that enabled the payroll (工資單) to be met for 2,700 teachers and staff in time for the holidays.
District officials also took $1.7 million from student-activity accounts of its 38 schools.
At Coffman’s request, the District Attorney has begun investigating the district’s finances. Coffman says he wants to know whether district officials hid the budget shortage until after the November election, when voters approved a $212 million bond issue for schools.
In Frederick, students’ parents are buying classroom supplies and offering to pay for groceries and utilities to keep first-year teachers and principals in their jobs.
Some $36,000 has been raised in donations from Safeway. A Chevrolet dealership donated $10,000 and forgave the district’s $10,750 bill for renting the driver educating cars. IBM contributed 4,500 packs of paper.
“We employ thousands of people in this community,” said Mitch Carson, a hospital chief executive, who helped raise funds. “We have children in the school, and we see how they could be affected.”
At Creek High School, three students started a website that displays newspaper articles, district information and an email forum. “Rumors about what’s happening to the district are moving at lighting speed,” said a student. “We wanted to know the truth, and spread that around instead.”
46. What has happened to the Vrain School District?
A. A huge financial problem has arisen.
B. Many schools there are mismanaged.
C. Lots of teachers in the district are planning to quit.
D. Many administrative personnel have been laid off.（A）
47. How did the residents in the Vrain School District respond to the budget shortage?
A. They felt somewhat helpless about it.
B. They accused those responsible for it.
C. They made their efforts to help solve it.
D. They demanded a thorough investigation.（C）
48. In the view of State Treasurer Mike Coffman, the educational budget shortage is ________.
A. unavoidable       B. unbelievable       C. insolvable        D. invisible（B）
49. Why did Coffman request an investigation?
A. To see if the financial problem was covered up on purpose
B. To find out how serious the consequence of the case would be.
C. To make sure that the school principals were innocent.
D. To stop the voters approving the $212 million bond issue.（A）
50. Three high school students started a website in order to ________.
A. attract greater public attention to their needs
B. appeal to the public for contributions and donations
C. expose officials who neglected their duties
D. keep people properly informed of the crisis

   In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened?  Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower?  Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
64. The whole passage is mainly about ________________.
A. predictions that have come true.
B. predictions that haven’t come true.
C. why predictions don’t come true easily.
D. what technology will bring about.
65. The author of this passage won’t believe that _________________.
A. predictions needn’t consider people’s practical use of technology.
B. the future isn’t always easy to guess.
C. not all past predictions have come true.
D. many of the high—tech things our parents thought we’d be using by now simply never appeared.
66. The underlined word “weird” probably means __________.
A. wonderful   B. stupid    C. practical    D. strange
67. What does the author think of the flying car?
A. It is too difficult to imagine.
B. It is too crazy an idea.
C. It is likely to be made.
D. It is often reported in the news.
