C
With smart phones taking the world by Storm，a phone that Can only send and receive voice
calls and text messages may seem like a relic from a bygone age．Yet in East Africa，simple
phones like these are changing the face of the economy，thanks to the mobile money services that are spreading across the region．
Usilng the text-messaging function built into the GSM system(全球通)used by most cell
phone networks，these services allow people without a bank account or credit card to use their
phone as an electronic walletthat can be used to store．send or receive cash．
It works like this：you pay cash to your local agent who then tops up your mobile money
account using a secure form of text messaging．That money can be transferred(轉(zhuǎn)賬)to another
person by sending a message to their cell phone account．
For some the system is a lifeline．“If I didn,t have my mobile phone．1 would be very
poor，”says Neyasse Neemur，a mother of four children who lives in northern Kenya．“Now I
can sell fish．”
Neemur took up fishing in July last year，but making money from it was a little tricky，
especially as Turkana people do not usually eat fish．A truck from Ethiopia to Tanzania passes
through her village once a week，and she arranged to have the driver transport the fish several
hundred kilometres south to market in Kisumu．where relatives sell the fish．
“I get the money transfer immediately．”says Neemur．“Then I can pay for my children to go to school and for vegetables and beans，”she adds，“so I don’t need to eat fish．”
According to the Central Bank of Kenya，payments worth around l billion Kenyan shillings
($13 million)per day were transferred through Kenya,s mobile money systems in 2009，equalling
the country,s credit card transactions(業(yè)務(wù))．The bank expects mobile money transfers to overtake credit cards in 2010．
49．In Paragraph l，the author uses“simple phones”to________.
A．make a comparison    B．introduce a topic
C．describe a scene     D．offer an argument
50．What can we learn about the simple phones in East Africa?
A．They might help the local people apply for a bank account．
B．They will replace the banks completely in the near future．
C．They provide a safe means for the locals to do business．
D．They can do nothing except send and receive calls or messages．
51．The word“it”in the third paragraph refers to_______.
A．the GSM system    B．the mobile money service
C．the credit card service D．the cell phone networks
52．The story of Neyasse Neemur suggests that_______.
A．the mobile money service plays a key rote in the locals, life
B．Neemur uses her mobile phone to contact her customers
C。her relatives tricks Turkana people to eat the fish they sell
D．the Bank of Kenya helps her improve her living condition

Findings from a new study were presented at a recent meeting of the American Psychosomatic Society. Researchers in the United States studied one hundred thousand women during an eight-year period, beginning in nineteen ninety-four. All of the women were fifty years of age or older. The study was part of the Women’s Health Initiative organized by the National Institutes of Health.
The women were asked questions that measured their beliefs or ideas about the future. The researchers identified each woman’s personality eight years after gathering the information.
The study found that hopeful individuals were fourteen percent less likely than other women to have died from any cause. The hopeful women were also thirty percent less likely to have died from heart disease after the eight years.
Hilary Tindle from the University of Pittsburgh School of Medicine in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.
The researchers also gathered information about people’s education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period.
Some women who answered the questions were found to be cynically hostile, or highly untrusting of others. These women were sixteen percent more likely to die than the others. They also were twenty-three percent more likely to die of cancer.
The study also found that women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely not to exercise.
Professor Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person’s physical health. She also says the study does not prove that negative emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.
1. What’s the purpose of carrying out the study?
A. To gather information for the National Institutes of Health.
B. To find out the relationship between women’s personality and their health.
C. To decide who is more likely to enjoy happier life.
D. To identify each woman’s personality 8 years after gathering the information.
2. What can be inferred from the passage?
A. It’s uncertain whether optimism affects a person’s physical health.
B. Negative emotions do cause shorter life.
C. The connection between personality and health has been established.
D. The more optimistic you are, the longer life you may enjoy.
3. According to the passage, who is more likely to die of cancer?
A. A woman who has high blood pressure or diabetes.
B. A woman who doesn’t exercise.
C. A woman who has poor physical health.
D. A woman who always doubts what others say.
4. Which of the following is true?
A. American Psychosomatic Society organized the new study.
B. Women who were optimistic were less likely to smoke.
C. More questions were given than those measuring women’s beliefs or ideas.
D. Hopeful women were 16% less likely to die from heart disease.

The unquestioned role of a student is to learn as much as possible through whatever means it takes to acquire knowledge. Teachers and professors are human beings and are therefore not perfect. No one knows the correct answer to every question even when you limit the questions to a certain field of study. Having certain skepticism (質(zhì)疑) about what they are being taught can help students to make the teachers even better by correcting mistakes and misinformation.
Students certainly have a huge role in their own abilities to learn. Teachers should act more as guides along the way rather than try to force each student to learn. The best teachers in the world cannot teach an unmotivated student. If the teacher, for whatever reason, cannot motivate the student, then the student must somehow find a way to motivate himself or herself.
One method of doing this is by becoming an active rather than a passive student. The more the student involves himself or herself in the act of studying, the better he or she can learn. One of the best ways to become more active is simply to ask the teacher or professor questions. Students who passively sit in a classroom and take everything that the teacher says for granted are not fully using their mental capacities(能力) to learn.
Better education comes from teachers who are able to get their students to think about a subject rather than merely absorb a certain amount of information. Having a healthy skepticism can improve a student’s ability to both think and absorb knowledge in a learning situation.
Teachers are human beings and no one is one hundred percent right all of the time, even in a classroom situation. Perhaps a teacher would simply unconsciously say the wrong word or pass on some misinformation that the teacher truly believed was correct. A student’s question could prevent an entire classroom from becoming confused or misinformed.
There is of course a fine balance between a student having a healthy skepticism, and just
being a downright(令人不快的) skeptic. But with the proper attitude toward learning and a little skepticism, both the students and teachers can improve upon the learning process and maximize learning efficiency.
64. Which of the following is the author’s main argument?
A. Passive learning results from passive teaching in class.
B. A student’s ability plays a huge role in the learning process.
C. A healthy skepticism fully depends on students’ motivation and ability.
D. A healthy skepticism and proper attitude contribute to effective learning.
65. Being passive learners, the students ________.
A. use little of their mental ability while studying
B. seldom involve themselves completely in learning
C. can hardly tell the right from the wrong in class
D. simply ask their teachers questions without thinking
66. According to the passage, a good teacher should ________.
A. help the unmotivated students patiently
B. instruct students in the learning process
C. make no mistakes in the teaching process
D. answer all the questions raised by students

四、閱讀理解（本題有16小題，每小題2分，共32分）
第一節(jié)：閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中，選出一個(gè)最佳答案。
It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. A large number of trees are being cut down to make paper. If everyone uses paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don’t know what to do with the waste in big cities. So it is necessary to reduce the waste.
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your used clothes or the small ones to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
3. Recycle
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat (壓平) and melted (融化) and the metal things are made for new coke cans.
4. Recover
When you buy a box of apples, there may be few rotten apples, you have two choices: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts. In this way, you are recovering the eatable parts of food.
5. Repair
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
51. The “Reduce” rule mainly requires us _______.
A. to use things wisely                          B. to cut down many trees
C. to use a lot of paper                          D. to throw away your old clothes
52. What’s the right order of recycling coke cans?
a. collect the used cans                              b. melt them
c. smash them flat                                     d. send them to a factory
A. a b c d                    B. a d c b                     C. d b c a                     D. c a b d
53. The “Recover” rule mainly requires us _______.
A. to throw waste things away                          B. to cover waste things with earth
C. to get back the useful parts                           D. to throw the whole things away
54. Which is the best way to do with your broken tables?
A. Throwing them away.                                  B. Repairing them.
C. Selling them.                                              D. Putting them away.

D
　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋轉(zhuǎn)),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活動(dòng)，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
　　　A.mean a warming - up im the Arctic
　　　B.raise the temperature of the earth's surface
　　　C.prevent the sun's rays from reaching the earth's surface
　　　D.account for great changes in the climate in the northern hemiphere
　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
　　　A.mainly because the levels of carbon dioxide are rising
　　　B.partly due to variations in the output of solar energy
　　　C.possibly because the ice caps in the poles are melting
　　　D.exclusively due to the effect of the inertia of the earth's climate
　　70.On the basis of their models,scientists are of the opinion that ________.
　　　A.the climate of the world should be becoming cooler
　　　B.the new Ice Age will be delayed by the greenhouse effect
　　　C.the man - made warming effect helps to increase the solar effects
　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

Thousands of people in the world are a hundred years old－or more and certain parts of the world are famous for the long lives of their inhabitants: the Vilacamba Valley in Ecuador, and the home of the Hunzas in the Himalayas．
Why do so many people live to a healthy old age in certain parts of the world? What is the secret of their long lives? Three things seem to be very important: fresh air, fresh food and a simple way of life．People work near their homes in the clean mountain air instead of travelling long distances to work by bus, car or train．They do not sit all day in busy offices or factories, but work hard outdoors in the fields．They take more exercise and eat less food than people in the cities of the West．For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors．There was no crime, no divorce and not much illness in their society． They were a happy, peaceful people, famous all over India for their long, healthy lives．
Do you want to live to a hundred years old? Here are some rules for success．Firstly, choose your parents and grandparents carefully．If they lived or live to a good old age, so will you．Secondly, live in the right place．Thirdly, choose the right  kind of job．Doctors, dentists and bus-drivers die young．Farmers, priests and orchestral conductors live much longer．If you are in the wrong kind of job, you can still improve your way of life．
An old man in the Caucasus was talking about his past life．"I was young then," he said, as he described his 87th year．His secret was: "Think young and stay young．" An old woman from Missouri, USA, gave this advice, "Drink a little whisky and some warm beer every day．" An English lady just said, "Take a cold bath every morning．" The shortest, simplest piece of advice came from Mr．Jim Chapman, aged 103．"Just keep breathing," he told reporters．
72．Who is most likely to live a long life?
A．A doctor．   B．A bus-driver．   C．A dentist．   D．An orchestral conductor．
73．We can see from the passage that long-lived people avoid ____．

An important factor that plays a part in susceptibility （易受影響） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．
The general frequency of colds continues to decline into adults．Elderly people who are in good health have as few as one or two colds annually．One exception is found among people in their twenties, especially women, who show a rise in cold infections（感染）, because people to this age group are most likely to have young children．Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections．
The study also found that economics （經(jīng)濟(jì)狀況） plays an important role．As income increases, the frequency at which colds are reported in the family decreases．Families with the lowest income suffer about a third more colds than families at the upper end．Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person．Low income may also influence diet．The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally．
68. What factors cause people to catch colds easily?
A. Age and pregnancy．             B. Health and pregnancy．
C. Health and economics．                  D. Age and economics．
69. Why does the lowest income lead to the rapid spread of colds?
A. Because poor people can't afford to go to see a doctor．
B. Because balanced diet has definitely affected poor people．
C. Because people with the lowest income have limited living space．
D. Because cold virus don't have opportunities to travel in poor families．
70. How does the study prove that age plays a part in susceptibility to colds?
A. Using comparison．  B. Using graphs．
C. Using description．  D. Using argument．
71. What can you learn from the passage?
A. Families with the lowest income suffer less colds than rich families．
B. The general frequency of colds are likely to increase among the poor．
C. Women in their twenties are most likely to avoid cold infections．
D. The general frequency of colds continue to rise into the adults．

Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品種)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
72. From paragraph 2 we know that _______.
A. animals are as clever as human beings
B. dogs are smarter than parrots and chimpanzees
C. chimpanzees have good word-learning skills
D. dogs have similar learning abilities as 3-year-old children
73. Both experiments show that_________.
A. Rico is smart enough to get all commands right
B. Rico can recognize different things including toys
C. Rico has developed the ability of learning mathematics
D. Rico won't forget the names of objects once recognizing them
74. Which of the following statements is true?
A. The purpose of the experiments is to show the border collie's mental abilities.
B. Rico has a better memory partly because of its proper early training.
C. The border collie is world-famous for recognizing objects.
D. Rico is born to understand its owner's commands.
75. What does the writer want to tell us in the last paragraph?
A. To train your dog.          B. To talk to your dog.
C. To be friendly to your dog.   D. To be careful with your dog.
