We sometimes think global warming or climate change is a problem very far away from our lives, and that only the government needs to worry about it. But it's hardly possible to completely stay out of it ­ scientists are now 95 percent sure that humans have been the “dominant cause” of global warming trends since the 1950s.
One of the conclusions of a report released on Sept 27 by the United Nations says that human activities have caused global temperatures to rise by 0.89 0C between 1901 and 2012. That might not seem like a lot, but the truth is that a major part of that heat has been absorbed into the oceans, which is not surprising given that they cover two thirds of Earth's surface. Also, water has a much greater capacity (容量) to absorb heat than the air does, according to The Economist. 
While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life, humans' use of fossil fuels is the main source of excess (多余的) greenhouse gases. According to CNN, by driving cars, using electricity produced by burning coal and oil or heating our homes with coal or natural gas, we release a large amount of greenhouse gases into the atmosphere.
Your body can barely feel a difference of 0.89 0C, but the Earth's ecosystems are so sensitive that even small changes can disturb them. It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct.
Global warming is also linked to an increase in extreme weather. A larger amount of carbon dioxide traps more energy inside the atmosphere. This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods. Worse still, melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year, according to The Guardian, which also increases the risk of flooding.
“The report should serve as another wake­up call that our activities today have a profound impact on society, not only for us, but for many generations to come,” French Michel Jarraud, secretary­general of the World Meteorological Organization, said at a news conference.
小题1:The underlined word “dominant” in the first paragraph means “ ________”.

A.is more harmful to smaller creatures than bigger ones
B.is not serious because most of the extra heat has been absorbed by the oceans
C.has made the Earth's ecosystems more sensitive to changes
D.is likely to cause many species to become extinct

Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer ― migrating birds fly in a "V" to save energy, according to a study published in the journal Nature.
When a bird flaps(振翅) its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost(抬高) from the rising air and therefore use less energy to stay in the air.
Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward.
"They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC.
In fact, the "V" formation has long thought to help birds fly more efficiently(效率搞地). A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof.
"For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies — helping them understand how they can imitate that with their plane formations to save fuel, said Portugal."
小题1:What is the author's purpose in writing this article?
A.To explain how birds benefit from migration.
B.To introduce how migrating birds find their way.
C.To tell some applications of migrating birds' "V" formations.
D.To report new findings about migrating birds' "V" formations.
小题2: According to the recent study, when birds migrate        .
A.they don't change their lead birds during the whole journey
B.they fly in "V" formations to protect themselves against enemies
C.they form the shape of a "V" to make best use of the lifting effect
D.the air they stir around makes it hard for the birds behind to fly fast
小题3:What is the significance of the new study according to this article?
A.It might inspire aircraft companies to think of ways to improve efficiency.
B.It has proved that the "V" formation can improve in efficiency in many fields,
C.It has led scientists to discover that birds' heart rates go down when they fly in a "V".
D.It shows that the best formation of jet fighters in battle should be a "V" formation.
小题4: The underlined word "imitate" in the last paragraph most probably means "        ".
A.useB.copyC.changeD.learn

The forces that make Japan one of the world’s most earthquake­prone (有地震倾向的) countries could become part of its long­term energy solution.
Water from deep below the ground at Japan’s tens of thousands of hot springs could be used to produce electricity.
Although Japanese high­tech companies are leaders in geothermal (地热的) technology and export it,its use is limited in the nation.
“Japan should no doubt make use of its resources of geothermal energy,” said  Yoshiyasu Takefuji,a leading researcher of thermal­electric power production.
The disastrous earthquake and tsunami on March 11,2011 caused a reaction against atomic power,which previously made up 30 percent of Japan’s energy needs,and increased interest in alternative energies,which accounted for only 8 percent.
Artist Yoko Ono has called on Japan to explore its natural energy,following the example of Iceland which uses renewable energy for more than 80 percent of its needs.
For now,geothermal energy makes up less than 1 percent of the energy needs in Japan,which has for decades relied heavily on fossil fuels and atomic power.
The biggest problem to geothermal energy is the high initial cost of the exploration and constructing the factories.Another problem is that Japan’s potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden.
“We can’t even dig 10 cm inside national parks.” said Shigeto Yamada of Fuji Electric,adding that regulations protecting nature would need to be relaxed for geothermal energy to grow.
Researcher Hideaki Matsui said,“Producing electricity using hot springs is a decades­long project.We also have to think about what to do for now as energy supplies will decline in the short term.”
The Earth Policy Institute in Washington,US,believed Japan could produce 80 000 megawatts (兆瓦) and meet more than half its electricity needs with geothermal technology.
Japanese giants such as Toshiba are already global leaders in geothermal technology,with a 70 percent market share.In 2010,Fuji Electric built the world’s largest geothermal factory in New Zealand.
小题1:What would be the best title for the text?
A.Alternative energies in Japan
B.World’s largest geothermal plant
C.Japan takes the lead in geothermal technology
D.Japan thinks of geothermal energy
小题2:What percentage of Japan’s energy needs is geothermal energy?
A.About 8%. B.Below 1%.
C.Around 30%. D.Over 80%.
小题3:According to Shigeto Yamada,the growth of geothermal power in Japan needs________.
A.a change of rules  B.financial support
C.local people’s helpD.high technology
小题4:Geothermal energy is considered as a long­term program by________.
A.Yoshiyasu Takefuji B.Hideaki Matsui
C.Shigeto Yamada D.Yoko Ono
小题5:It can be learned from the last two paragraphs that________.
A.the world’s biggest geothermal plant was built by America
B.Japan will not export its geothermal technology
C.the potential of Japan’s geothermal energy is great
D.it is hard to find geothermal energy in Japan

 Global Positioning Systems(GPS) are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two.
We spoke to Mr. Brown by Skype (网络电话软件). He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. BARRY BROWN: “And they just plugged in an address and then set off to their destination. And, then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'.”
Mr Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. BARRY BROWN: “One problem with a lot of the GPS units is that they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people’s cars. They wrote a paper based on their research. It is called “The Normal, Natural Troubles of Driving with GPS.”
It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues(时机问题) related to when GPS commands are given.
Barry Brown says, “ To make GPS systems better we need a better understanding of how drivers, passengers and GPS systems work together.”
小题1:In paragraph 2, Mr. Brown mentioned his friend in the conversation to _______.
A.build up his own reputation
B.laugh at his stupid friend
C.prove the GPS system is only garbage
D.describe an example of human error
小题2:What is the disadvantage of small screens in GPS equipment according to the text?
A.They just provide the next turn.B.They are harmful to eyes.
C.They make drivers tired easily.D.They often break down suddenly.
小题3: Which of the following statements would Barry Brown most likely agree with?
A.GPS units are to blame for most GPS service failures.
B.We should introduce higher standards for the driving license.
C.Cameras are urgently needed to help improve GPS systems.
D.Drivers, GPS systems and passengers should unite to improve GPS systems.
小题4:What is Mr. Brown’s attitude towards GPS?
A.Unconcerned.B.Prejudiced.
C.Objective.D.Critical.
小题5:Which of the following statements can best describe the main idea of the pasage?
A.Driving with GPS can be difficult.
B.Driving confusions can be caused by small screens.
C.Driving without GPS should be much more convenient.
D.GPS equipment in driving to be deserted or improved

Seven species of carp(鲤鱼) native to Asia have been introduced into United States waters in recent decades, but it's four in particular-bighead, black, grass and silver-that worry ecologists, biologists, fishers and policymakers alike. Introduced in the southeast to help control weeds and parasites in aquaculture (水产养殖) operations, these fish soon spread up the Mississippi River system where they have been crowding out native fish populations not used to competing with such aggressive invaders. The carps' presence in such numbers is also harming water quality and killing off sensitive species.
Asian carp are strong to jump over barriers such as low dams. They lay hundreds of thousands of eggs at a time and spread into new habitat quickly and easily. Also, flooding has helped the fish expand into previously unattainable water bodies. And fishers using young carp as live bait have also helped the fish's spread, as they have boats going through locks up and down the Mississippi.
The federal government considers the Asian carps to be annoying species and encourages and supports “active control” by natural resources management agencies. Federal and state governments have spent millions in tax dollars to prevent the carp from making their way into the Great Lakes, but an underwater electric fence constructed to keep them out has not worked as well as hoped, and policymakers are reviewing other options now.
In the meantime, state and federal agencies are monitoring the Mississippi and its branches for Asian carp and testing various barrier technologies to prevent their further spread. For instance, the National Park Service is cooperating with the state of Minnesota's Department of Natural Resources to construct new dams that are high enough to prevent Asian carp from jumping over. The Asian Carp Regional Coordinating Committee has funded DNA monitoring in potentially affected water bodies whereby researchers can determine whether the troublesome fish are present just by the biological footprints they leave behind. Individuals can do their part by not transporting fish, bait or even water from one water body to another, and by emptying and washing boats before moving them between different water bodies.
小题1:Asian carp have been introduced to the USA in order to ________.
A.improve water quality
B.help sensitive species
C.control the number of native fishes
D.control the ecosystem in aquaculture
小题2:The measure to keep Asian carp out of the Great Lake but proved not good is ________.
A.testing various barrier technologies
B.construction of an underwater electric fence
C.Emptying and washing boats before using them.
D.monitoring the Mississippi and its branches for Asian carp
小题3:It is suggested from the passage that ________.
A.aquaculture operations are dangerous to the water bodies
B.scientific technology is useless in preventing Asian carp spreading
C.both the state and the individuals can make efforts to keep out Asian carp
D.Asian carp have successfully invaded the Mississippi and the Great Lakes

New findings from Queen’s University biologists show that in the plant world, bigger isn’t necessarily better.
“Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” says Queen’s Biology professor Lonnie Aarssen. “But our research shows it’s virtually the other way around.”
Previous studies showed that larger plant species monopolize(垄断) sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But the research has proved that this is not generally the case in natural vegetation.
In the Queen’s project, PhD student Laura Keating targeted the largest “host plants” of 16 woody plant species growing in the Okanogan Valley, British Columbia. The research team calculated the number and variety of plants that neighbored each large host plant. They then randomly selected plots without host plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist.
Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space niches under their shelters where smaller species grow well. Smaller plants are much more effective than large trees at using available resources. They also produce seeds at a much younger age and higher rate than their bigger counterparts, and settle down much more quickly—thuscompeting with the newly-born plants of larger species.
小题1: What’s the main idea of the text?
A.Smaller plants may have many advantages over their neighbors.
B.In the plant world, the bigger is better than the smaller one.
C.To be a good competitor in the forest, you have to be a small plant.
D.Queen’s University’s students made a new research.
小题2: The underlined word “this” in Para. 3 refers to the view that _____.
A.large and small plants can grow together in harmony
B.larger plant species limit their smaller neighbors’ growth
C.small plant species have their own advantages
D.large and small plant species can never coexist
小题3:What can we learn according to the text?
A.Larger plant species limit the number of smaller ones around them.
B.Smaller plants can limit the number of plant species around them.
C.Smaller plants produce seeds at a higher rate than their bigger counterparts.

There are many things that go into making a successful school, and success can be measured in many ways. Often, the teachers are praised for a school’s success and blamed for its failure. Yet, in order for a school to be effective, it must be a place where teaching and learning can easily take place, and that requires the hard work of more than just educators. Students must take learning into their own hands and feel as if what they are doing is as important as it actually is. This can only be done with the cooperation of every adult that is involved in the students’ life. Some of these individuals often go unnoticed, yet the role they play in the students’ lives is immeasurable.
Administrative assistants welcome students at the beginning of the day and answer a large number of questions. When an assistant remembers a student’s name or even something special about that student, it communicates to him that he is cared for. The assistant can also give that extra encouragement for a student to make better choices, especially when they are visiting the principal’s office.
Cafeteria workers have a short period of time to interact with students, but can make a big difference as well. Beyond meeting nutritional needs, cafeteria workers may also on occasion meet the emotional needs of the students they serve. Students benefit from positive interaction with adults, and cafeteria workers may give that extra bit of encouragement that a child needs.
Custodians (管理人员) are often underappreciated for all that they give to schools. They have to be knowledgeable about everything from cleaning to fixing the most intricate (复杂的) tools. They get to school early in the morning before teachers arrive and lock up late at night after the last student has left from the after-school event. They also make sure teachers are equipped with the necessary items and prepare the rooms so that they are ready for learning. A great custodian also gives that kind word or extra smile to that student who needs it most.
小题1:If an assistant remembers a student’s name, the student will feel that       .
A.he is cared for
B.he is special
C.he has done something wrong
D.he has made progress in study
小题2:Which of the following is TRUE about cafeteria workers?
A.It’s enough for them to cook for the students.
B.It’s hard for them to interact with the students.
C.They can also meet the emotional needs of the students.
D.They have the most interaction with students at school.
小题3:We learn from the fourth paragraph that       .
A.custodians play the least important role in a school
B.the work of custodians often goes unnoticed
C.custodians should be more serious with students
D.custodians’ work is always appreciated at school
小题4:How does the author feel about the staff mentioned in the text?
A.Disappointed. B.Appreciative.
C.Dissatisfied. D.Doubtful.

Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress. This difference may explain why men are more likely to suffer from stress-related disorders.
Until now, psychological research has maintained that both men and women have the same "fight-or-flight" reaction to stress. In other words, individuals either react with aggressive behavior, such as verbal or physical conflict ("fight"), or they react by withdrawing from the stressful situation ("flight"). However, the UCLA research team found that men and women have quite different biological and behavioral responses to stress. While men often react to stress in the fight-or-flight response, women often have another kind of reaction which could be called "tend and befriend." That is, they often react to stressful conditions by protecting and nurturing their young ("tend"), and by looking for social contact and support from others - especially other females ('befriend").
Scientists have long known that in the fight-or- flight reaction to stress, an important role is played by certain hormones(激素) released by the body. The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied in the context of childbirth, but now it is being studied for its role in the response of both men and women to stress. The principal investigator, Dr. Shelley E. Taylor, explained that "animals and people with high levels of oxytocin are calmer, more relaxed, more  social, and less anxious." While men also secrete(分泌)oxytocin, its effects are reduced by male hormones.
In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions if they are lost.
The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children and their needs.
The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend regulatory(调节的) system may protect women against stress, and this may explain why women on average live longer than men.
小题1:The UCLA study shows that in response to stress, men are more likely than women to _____ .
A.turn to friends for helpB.solve a conflict calmly
C.find an escape from realityD.seek comfort from children
小题2:Which of the following is true about oxytocin according to the passage?
A.Men have the same level of oxytocin as women do.
B.Oxytocin used to be studied in both men and women.
C.Both animals and people have high levels of oxytocin.
D.Oxytocin has more of an effect on women than on men.
小题3:What can be learned from the passage?
A.Male hormones help build up the body's resistance to stress.
B.In a family a mother cares more about children than a father does.
C.Biological differences lead to different behavioral responses to stress.
D.The UCLA study was designed to confirm previous research findings.
小题4:Which of the following might be the best title of the passage?
A.How men and women get over stress
B.How men and women suffer from stress
C.How researchers overcome stress problems
D.How researchers handle stress-related disorders
