An earthquake is caused by a sudden slip on a fault, or fracture, in the earth"s surface. The tectonic plates on the surface are always slowly moving, but they get stuck at their edges because of friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth"s crust and create the shaking we feel.
An earthquake"s degree is a measured value of its size and is the same no matter where you are, or how strong or weak the shaking was in different locations. An earthquake"s intensity is a measure of the shaking it creates, and varies with location.
A degree of 8 or higher defines a “great” earthquake; 7 to 7.9 is considered “major”; 6 to 6.9 is “strong”;5 to 5.9 is “moderate”; 4 to 4.9 is “light”; 3 to 3.9 is "minor"; and less than 3 is “micro.”
Experts have said that a million people died in earthquakes in the 20th century and that this century might see 10 times as many deaths, with as many as a million killed in a single quake. That is, unless major efforts are made to fortify the world’s growing cities, which are expected to be homes to billions of added residents.
Even though the rate of earthquakes over time seems to be more or less unchanging, the world"s population explosion means that more people are moving into quake zones, which are often near coasts. The result, the experts say, is the prospect of continuing trauma.
“It is inevitable,” Klaus H. Jacob, an earthquake expert at Lamont-Doherty, the earth sciences research center of Columbia University, said at the end of the last century. “More and more people, and more and more buildings, are at stake . As the world gets more populous and richer, allowing a more built-up environment, higher buildings and all the infrastructure that supports our civilization, communications and the like, the risk goes up.”
63. We can feel the earthquake because
A. the plates are always moving.
B. the stress overcomes the friction.
C. the plates get stuck.
D. the waves in which energy is released travel through the earth’s crust.
64. a degree of 8.2 is thought
A. a “moderate” earthquake. B. a “major” earthquake .
C. a “strong” earthquake. D. a “great” earthquake.
65. Experts have said that
A. a billion people died in earthquakes in the 20th century.
B. ten times as many deaths will be seen by this century.
C. a million people will be killed in a single earthquake this century.
D. if we don’t take measures, something worse may happen.
66. The underlined expression probably means .
A. endangered B. strong C. safe D. weak

Beijing retiree Yang Hua was devoting a lot of his time to staying fit by completing his favorite exercises. But, according to his doctors, his routine may have done more harm than good—he recently suffered an illness because he was exercising the wrong way.
“Many people today still do not know how to exercise in scientific ways. As a result, they do not gain from the exercises and in fact may even hurt themselves, said Yang Zeyi, an executive board member of the Asian Council of Exercise and Sports Science.
Health experts said that a cardiopulmonary(心肺的) exercise test is necessary for middle-aged and senior citizens and those with special conditions. The test helps those engaging in exercise know whether their routines(惯例) are safe. It also can find potential unhealthy changes to exercisers" organs and provide suggestions to get fit by conducting real-time and continuous measurement of blood pressure and other physical parameters. The test can also analyze the maximum functioning of which the cardiopulmonary system is capable.
In the past, Yang would not think of creating an exercise plan because of his physical condition.
“I liked to do exercises in the evening but experts told me that the high-strength exercises at night would be harmful to my health. They advised me to choose some easy exercises such as walking and to limit the length of time I exercise,”he said. Sun Kanglin, Director of the Beijing Municipal Bureau of Sports, said, “Exercisers should choose a proper routine and length of time to engage in the activity according to their age, physical condition and profession. It"s important to give scientific directions to today"s exercisers.”
He said Beijing"s 18 districts and counties all have physical monitoring stations where people could get suggestions on how to exercise.
“The number of such stations will increase to more than 100 in the future and they will be able to regularly monitor citizens’ physiques. They will also publish statistics for the public,” he said.

Visiting the Arctic
ZHOU Mingfeng, 17, has only stepped out of his birthplace, Qingdao, once to visit the top of the world, the Arctic!
The Senior 2 student from the High School Attached to Ocean University of China joined a two-week journey to the Arctic at the beginning of this month, after he was recommended for the trip. Including his teacher, Wu Jianying, the adventure group consisted of 12 students and teachers from China, Spain, Canada, Britain and the US.
“The trip brought the whole subject of geography and climate change to life,” Zhou said.
Before they landed by air on Canada’s research icebreaker (破冰船) in the Arctic, Amundsen, the group visited an Inuit (英纽特人的) community. Zhou also got the chance to experience dog-sledding for the first time!
He was surprised to find that Inuit people don’t live in snow igloos (圆顶建筑) any longer. “They live in modern, warm wooden houses and travel mostly by snowmobile,” he said.
During the time on board Amundsen, every day was science orientated (以……为主). Zhou and other teenagers were guided by scientists, who work there, to take part in laboratory and field work. Sometimes they went outside to collect ice and snow samples for experiments despite the windy, freezing climate.
As the only Chinese student, Zhou didn’t feel very confident due to his English inefficiency.
“Those students soon got close to the onboard scientists and became involved (参与) in their research,” he recalled in admiration.
However, it didn’t prevent Zhou from enjoying the unique and remote life there.
When the wind died and the sun shone on the frozen desert, Zhou and his new friends recorded their days with photo shoots out on the ice beside the Amundsen!
“The views were breathtaking! Everything around us seemed lifeless, which is shocking,” he said.
But there proved to be something alive, under the ice caps. A seal popped out of the water below the ship and greeted them on the last day of their stay.
“It was the only animal I saw in the Arctic!” he said. “But it’s a pity that I didn’t see a single polar bear in the ‘capital’ of the creature.
59. According to the passage, the students and teachers visiting Artic are most likely to _______.
A. go sightseeing B. take part in some science research
C. learn English D. learn about Inuit community
60. In the passage, Amundsen is _________.
A. an icebreaker B. an Inuit igloo C. a place in Artic D. a dog-drawn sled
61. Which of the following is NOT true according to the passage?
A. Zhou was surprised to find the Inuit lived in modern, warm wooden houses.
B. Zhou visited an Inuit community first.
C. Zhou’s inefficient English made him unable to enjoy the life in Artic.
D. Zhou took many photos with his new friends.
62. The underlined sentence “The trip brought the whole subject of geography and climate change to life,” in Paragraph 3 probably means _________.
A. The trip made what had been learned in geography lessons more vivid or interesting.
B. The trip suddenly started working.
C. The trip completely changed his life.
D. The trip made animals in Artic live.
Growing up the daughter of an outstanding educator, Andrea Peterson knew at a young age that she wanted to serve others. It was with this mindset that she started to pursue a degree in medicine. However ,while visiting her brothers who were away at college studying music education, she realized that she too was drawn to teach music.
In her ten years at Granite Falls, she has revitalized the music programs at both the elementary and high school levels,to the extent that an additional music faculty member was hired by the district to assist with the workload. The growth of the music program in Granite Falls School District has encouraged students to participate in county ,state ,and national music competitions ,and won numerous prizes for the district.
Teaching music is only part of Peterson"s instruction-it serves as a vehicle to other areas .
"Music is an amazing tool to unlock students" potential. The most visible benefit from their success in music is their increased confidence and self-esteem," Peterson said. "However, I don"t believe it is the only benefit, nor the most powerful. It is truly exciting to see how my music teaching can transfer back to other classrooms." With this philosophy, Peterson introduced a cross-curriculum program ,wherein she takes lessons taught in other classes, such as English and math ,and expands upon them in an eight-week unit.
One of the most popular projects in Peterson"s classes in the creation and performance of a musical, whereby students create a play from one of the books they have read in another class. Students work together to choose the music that best fits with the overall feel of the play and then perform it for the greater community. "Through Andrea"s efforts these kids have helped to put Granite Falls, Washington, on the map for musical talents. Parents, staff ,and community members continue to be in awe of what she is able to bring forth from the children," said Debra Rose Howell, a colleague of Peterson"s at Monte Cristo Elementary School.
69.Initially Andrea Peterson Planned to work as a (n)______.
A.teacher B.doctor C.educator D.musician

At a laboratory in Germany ,volunteers slide into a machine and perform simple tasks, such as deciding whether to add or subtract two numbers , or choosing which of two buttons to press.
They have no idea that scientists in the next room are trying to read their minds-using a brain scan to figure out their intention before it is turned into action.
In the past ,scientists had been able to detect decisions about making physical movements before those movements appeared .But researchers at Berlin"s Bernstein Center for Computational Neuroscience claim they have now , for the first time ,identified people"s decisions about how they would later do a high-level mental activity-in this case ,adding versus subtracting.
While still in its initial stages ,the techniques may eventually have wide-ranging implications for everything from criminal questioning to airline security checks.
The research,which began in July 2005,has been of limited scope:only 21 people have been tested so far.And the 71 percent accuracy rate is only about 20 percent more successful than random selection.
Still ,the research conducted at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig ,about 150 kilometers southwest of Berlin ,has been generating strong interest in the scientific community.
In one study ,participants were told to decide whether to add or subtract two numbers a few seconds before the numbers were flashed on a screen . Meanwhile ,a computer captured images of their brain waves to predict the subject"s decision-with one pattern suggesting addition, and another subtraction.
The team ,headed by Haynes ,began its research by trying to identify which part of the mind was storing intentions. They discovered it was found in the prefrontal cortex region by scanning the brain to look for bursts of activity when subjects were given choices.
Then they went about studying which type of patterns were associated with different intentions.
"If you knew which thought signatures to look for ,you could theoretically predict in more detail what people were going to do in the future," said Haynes.
75.Which of the following is true about the experiment at the laboratory?
A.The volunteers are asked to perform very complicated tasks.
B.Everything was explained to the volunteers before the experiment.
C.The volunteers cannot see the scientists while performing the tasks.
D.The volunteers started the experiment by pressing one of the two buttons.
76.Which of the following demonstrates the major breakthrough made by the German scientists?
A.By studying the subjects" brain waves , they know what physical movements they"ll make.
B.By studying the subjects" brain waves, they know what mental task they"ll perform.
C.By studying criminals" brain waves ,they can help find out whether they are lying or not.
D.By studying passengers" brain waves ,they can help find out who intends to make trouble.
77.In the research which began in July 2005 only______subjects" brains were scanned and the accuracy rate was______.
A.21; 20% B.71;20% C.21;71% D.20;71%
78.The group of scientists in Leiqzig were doing______what the group in Berlin were doing.
A.similar research to B.better research than
C.completely different things from D.a less satisfactory job than
79.The term thought signatures in the last paragraph refers to______.
A.the subjects" intentions B.the subjects" physical movements
C.parts of the human brain D.the human brain wave patterns
80.From the information in the passage, it can be concluded that in the future______.
A.the intentions of people can be predicted accurately
B.it"s impossible to predict accurately the intentions of people
C.no one in the world will dare to tell lies to other people
D.everyone will easily know what others are thinking about
