The following conversation is between Susan Russell-Robinson from the US Geological (地質(zhì)學的)Survey and Barbara Reynolds from USA Today .
Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt(噴發(fā))in 1991 ?
A: Volcanoes (火山)each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years .
Q: So nothing caused it ?
A: There’s nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that .
Q: What is “the ring of fire” ?
A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world’s volcanoes lie .
Q: Why such a concentration(集中)there ?
A: That’s based on a theory that the oceans and the continents are like separate pieces . When they move , one might ride up over the other one . In this case , the Pacific Ocean goes under the continents and when that happens it seems to produce magma (熔巖)at depth and then you have volcanoes in the same ring .
1.What kind of writing do you think this passage is ?
A.A text taken from a geography book .    B.An interview published in the press .
C.A conversation carried out in a film .     D.An oral test recorded as an example .
2.Which of the following statements can correctly explain why we have so many volcanoes around the Pacific Ocean ?
A.The movement of the surface of the earth makes it possible.
B.The Pacific Ocean produces magma and presses it everywhere.
C.The oceans and the continents are separated from each other.
D.The earth’s surface around the Pacific is thinner than any other part.
3.Barbara Reynolds’ main purpose here is______________ .
A.to show how dangerous volcanoes are to the world
B.to learn what signs a volcano gives us before its eruption
C.to warn the world of the existence of “the ring of fire”
D.to introduce some general idea of volcanoes to the public
4.Which of the following can be considered as the best conclusion of the conversation?
A.There are so many volcanoes in the world and we are always in danger.
B.Volcanoes have erupted more frequently than ever before.
C.Volcanoes are waiting to be better known.
D.Something must be done to protect the people near the ring of fire.

Student Services
Students' Union
Every University has a Students' Union. If students are the lifeblood of a university, the Union is surely its beating heart.
For students, by students
A Students’ Union is run by students and acts independently. At the end of each academic year, it will find six students to hold a sabbatical(帶有休假的) position managing the Union for the coming year. That the six successful sabbatical officers have only recently experienced issues affecting students ensures that your needs are very well understood.
Letting your hair down
Although the University is spread across a fairly wide area, the Union is centrally located and is only a short walk from any of the main buildings. This makes it very easy to catch up with friends who might be on a different course.
At night, the place really comes alive – we have three different bars to suit every occasion. The venues are student-only so you can be sure of meeting people with a similar outlook and we throw in a transport service to make sure you get home safely.
The Union also organizes various formal balls throughout the year, with the highlight being the end-of-year ball.
Supporting you
Beyond having fun, we also make sure some of the more serious issues are effectively dealt with. If you have a problem with your course, another sabbatical officer is trained to help you. Being independent from the University means we can represent and support you to the best of our ability, and once you reach university you may find that you become aware of more national or political issues.

The invention of the electric telegraph gave birth to the communications industry. Although Samuel B. Morse succeeded in making the invention useful in 1837, it was not until 1843 that the first important telegraph line was constructed. By 1860 more than 50,000 miles of lines connected people east of the Rockies. The following year, San Francisco was added to the network.
The national telegraph network strengthened the ties between East and West and contributed to the rapid expansion of the railroads by providing an efficient means to monitor schedules and routes. Furthermore, the extension of the telegraph, combined with the invention of the steam-driven rotary printing press by Richard
M. Hoe in 1846, revolutionized the world of journalism. Where the business of news gathering had been dependent upon the mail and on hand-operated presses, the telegraph expanded the amount of information a newspaper could supply and allowed for more timely reporting. The creating of the Associated Press as a central wire service in 1846 marked the arrival of a new era (紀元) in journalism.

Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It’s hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.
For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely (反過來), boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.
Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex (大腦皮層), enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.
Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore, parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
67.What is the main idea of the passage?
A. Boys tend to pay less attention in class than girls.
B. Girls are better than boys in their ability to detect sounds.
C. Boys and girls behave differently because of biological differences.
D. Single-sex schools are not good because they keep boys and girls separate.
68.Why do girls express negative feelings better than boys?
A. Girls are more emotional than boys.
B. Girls have more brain cells than boys.
C. The amygdala is located in different areas of the brain for boys and girls.
D. The links between certain parts of the brain develop earlier in girls than in boys.
69.Which of the following does the author believe?
A. Girls need more training in communication.
B. Boys and girls should be educated in different ways.
C. Parents should pay more attention to boys.
D. Sex differences should be ignored in education。
70.What does the phase “cling to” in the first paragraph mean?
A. maintain               B. abandon                         C. evaluate          D. challenge

American and British researchers have proved that judgments based on how someone looks are important. They found that appearance tells a lot about your personality.
The researchers included Laura Naumann of Sonoma State University in California, and Simine Vazire of Washington University in Saint Louis, Missouri. They were joined by Sam Gosling of the University of Texas at Austin and Peter J. Rentfrow of Britain's Cambridge University. The results of their study were published in the Personality and Social Psychology Bulletin in December, 2009.
The subjects(接受實驗者)were asked to judge the personality of people they had never met. The judges examined pictures of one hundred twenty-three people. The people in the photographs had been told how to stand. They looked into the cameras without showing their feelings. The same people also were photographed the way they themselves wanted to stand. Those who wanted to smile could smile.
Then the judges attempted to decide what the people were like. The researchers compared the judges’ opinions with the way the people who were photographed thought of themselves. Three people who knew those in the photographs well also provided information about their personality and behavior.
The judges looked for ten qualities in the people in the pictures. The qualities included extroversion (having a confident character and enjoying the company of other people) and self-esteem (being satisfied with oneself).
The judges also looked for signs of loneliness, conscientiousness(正義), emotional control and religious and political beliefs.
The researchers said the judges could identify some personalities even when people were pictured in controlled positions. They could recognize personalities like extroversion and self-esteem. But it was hard for the judges to decide about most other personalities under the controlled conditions.
When the people smiled and stood naturally, however, judging their personalities was easy. Then the judges’ choices were correct for nine of the ten personalities.
Researcher Laura Nauman said that we live in the world where first impressions are important.
1. According to the passage, who were the judges?
A. The researchers of the study.                       B. The subjects in the study.
C. Parents and other adults.                               D. People in the photographs.
2. Which of the following qualities could the judges identify even when people were pictured in controlled positions?
A. Extroversion                   B. Religious beliefs              C. Loneliness         D. Emotional control
3. We can infer from the passage that ____________
A. the study was carried out by four researchers from America.
B. in the study126 people were photographed for judges to decide their personalities.
C. the Personality and Social Psychology Bulletin is an official publication(出版物).
D. it was hard to recognize personalities when the people were pictured with natural looks.
4. What will the author most probably talk about next?
A. The quality of the judges.                      B. The personalities of Laura Nauman.
C. Signs of emotional control.                   D. The reason why one’s appearance is important.

A survey has found that in adolescence (青春期) a lack of physical activity is connected with emotional and behavioral problems. More than 7,000 teenagers in Finland took part in the survey that judged their levels of physical activity and mental and emotional health. Boys who reported less than one hour of physical activity a week were more likely to be anxious and sad than boys who were more active. Girls who were not active had similar problems, and were more likely than boys who were not active to have sleep problems and break school rules.
The researchers concluded that both boys and girls who are not active are more likely than active ones to have social and attention problems.
“Adolescence is already a difficult stage of life-emotionally, mentally and physically,” study author Marko T.Kantomaa said in the American College of Sports Medicine.
“Mixing that with negative mental and emotional effects brought on by lack of physical activity does not help young people enter adulthood smoothly. Physical activity could be a highly effective and relatively easy way to help that transition and could lead to healthy habits for one’s whole life,” Kantomaa said.
Researchers said that evidence suggests that an increase in physical activity helps reduce problems of sadness and anxiety in both adolescents and adults. “It seems that there is a psychological(心理的)and physiological(生理的)connection that helps explain the beneficial effects of exercise on mental health,”Kantomaa said.
1. The first paragraph leads us to believe that________.
A. a lack of physical activity may cause many mental problems
B. a lack of physical exercise is common among teenagers
C. girls have more physical and mental problems than boys
D. inactive boys are more likely to break rules than inactive girls
2. Which of the following problems may NOT be caused by a lack of activity according to the passage?
A. Anxiety.     B. sleeplessness.    C. Inattention.   D. unkindness.
3. From the passage we can conclude that___________.
A. boys take more physical exercise than girls
B. teenagers who aren’t active spend a lot of time studying
C. plenty of physical activity is effective in developing healthy habits
D. physical exercise is the only way to cure mental problems
4. The underlined word “transition” in the fourth paragraph is closest in meaning to“_______”.
A. change      B. condition       C. balance       D. activity

Electric cars will not be really much cleaner than autos powered by mineral fuels until they rely less on electricity produced from usual coal-fired power plants.
“For electric vehicles to become a major green alternative, the power fuel has to move away from
coal, or cleaner coal technologies have to be developed,” said Jared Cohon, the chairman of a National
Research Council report released on Monday. About half of US power is produced by
burning coal, which gives off many times more of traditional pollutants than natural gas, and about
twice as much of the main greenhouse gas carbon dioxide. Nuclear and renewable power have to
generate a larger portion of US power for electric cars to become much greener compared to
gasoline-powered cars, Cohan, who is president of Carnegie Mellon University, said in an interview.
Advances in coal burning, like capturing carbon at power plants for permanent burial underground,
could also help electric cars become a cleaner alternative to vehicles powered by fossil fuels, he said.
Pollution from energy sources did $120 billion worth of damage to human health, agriculture and
recreation in 2008, and electricity was responsible for more than half of the damage, said the NRC
report.
Electric cars have their benefits such as reducing imports of foreign oil. But they also have hidden
costs. Materials in electric car batteries are hard to produce, which adds to the energy it takes to make
them. In fact, the health and environmental costs of making electric cars can be 20 percent greater
than usual cars, the report said.
The report estimated that electric cars could still cost more than gas-powered cars to operate and
manufacture in 2030 unless US power production becomes cleaner.
1. Why are electric cars not clean enough?
A. Because they run too slowly              B. Because they are too expensive
C. Because they rely on coal-fired power.      D. Because they give off more carbon dioxide.
2. We can infer from the passage that ______.
A. electric cars will soon take the place of gas-powered cars
B. no one holds hope for electric cars at present
C. electric cars waste more energy than before
D. some people believe that electric cars are cleaner
3. The underlined word “them” refers to “______”.
A. electric cars     B. batteries       C. producers        D. materials
4. Which of the following is NOT mentioned as a way to make electric cars cleaner?
A. Developing cleaner coal technologies.        B. Making electric cars run faster.
C. Generating more unclear power.             D. Making advances in coal burning.

What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportu­nity to make money.
Eight students from No 2 Secondary School Attached to East China Normal Uni­versity started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction a week a­go. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months.
"We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of ‘spreading love and culture with seeds’ after many tests and lots of hard work," said Senior 2 Shi Chen, CEO of the compa­ny.
Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought seeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds.
With little business knowledge, the students had to learn new skills as the lead­ers of different departments, such as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management. They also asked some local businessmen to act as their consul­tants.
"They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication skills and teamwork are very important for my job," said Senior 1 Qian Yifei.
The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions.
As the head of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently as the company only opens at weekends due to all their studies. So she established a system to evaluate every one's performance, in terms of punctuality, efficiency, profits knowledge and so on.
"It makes the company more formal," she said.
59. What is the purpose of opening the company?
A. To earn money for their education fees.
B. To spread love and culture with seeds.
C. To see whether they can open a company.
D. To collect money to open a Hope School.
60. At a campus auction a week ago, they ________ .
A. sold 28 green plants with different flowers
B. sold 28 seeds pasted with different pictures
C. sold 28 pictures pasted with different seeds
D. sold 28 flowers pasted with different pictures
61. According to Qian Yifei, what matters most in dealing with public relations?
A. Communication skills and teamwork.
B. Creative and critical thinking.
C. Educational background.
D. Business theories.
62. What does the word "it" (in the last paragraph) refer to?
A. Selling seeds.
B. To have a person as CEO.
C. Every colleague’s performance.
D. To make her colleagues work efficiently.
63. What can we learn from the passage?
A. The company is owned by 8 students.
B. The company is over-night successful.
C. The company gets a lot of help from others.
D. The company sells old books and fresh flowers.
