    A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers． The study-in Benin found that solar - powered pumpsare effective in 8upplying water, especially during the long dry season．
    Sub - Saharan Africa is the part of the world with the least food security． The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world' s peo-ple faced hunger last year．Around 265 million of them live'south of the Sahara Desert:  Lack of  rainfallis one oftheir main causes offood shortages．．
    Jennifer Bumey from Stanford University in Califomia led the study．The research team helped build three solar - powered drip irrigation -（滴灌） ,systems in northem Benin． Between 30 and 35 women used each system to pump water from the ground or a stream．Each woman was responsible for farming her own 120 sqrurre meters of land． They also farmed other land  collectively．
    The solar - powered irrigation systems produced an average of nearly two tons of vegetables per montb． During the first year, the women．kept a monthly average of almost rune kilograms of vegetables for home use．They sold the surplus produce at local markets． The eamings greatly increased their ability to buy food during the dry season which can last six to nine months． Peo- ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day．But making the surplus available at markets also had a wider effect．
    The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets． The amount of vegetables eaten in those villages also  increased, though not as much．The researchers note that only four percent of the croplamd in sub - Saharan Africa is irrigated． Using solar power to pump water has higher costs at first． But    the study says it can be more economical in the long term than using fuels like gasoline,  diesel  or kerosene． And solar power is environmentally friendly．
    66．Food security in Sub - Saharan Africa is insufficient mainly because of
    A．lack of rainfall         B．limitation of farmland
    C． a small crop variety   D．little sunlight
    67．From the third paragraph we know that _______．
    A．water is wasted by using the system
    B． the farmers imgate the land together
    C． all farmers use irrigation systems in northem Benin
    D． the solar - powered systems take up more manpower
    68．The underlined word "surplus" in the 4th paragraph most probably means_______
    A．special             B．unnecessary      C．extra      D．abandoned
    69．Usinf．solar power to pump water has advantages EXCEPT that
    A．solar energy has higher cost at first
    B．solar power helps to protect environment
    C．solar power helps farmers increase eanungs
    D． solar energy can be more economical in the long run
    70．What can be the best title for the text?
    A．Manpower affects rainfallin Africa
    B．Irrigation by carrying water in buckets
    C．Solar - powered pumps aid African farmers
    D．Vegetable supply increased in African villages

    第三部分任务型阅读（满分10分）
    Romantic novelists rarely fail to include in their writings that special moment when two strangers look into each other's eyes across a crowded room and feel the tingle of desire. Now these writings have now been validated（证实）by science, for experts have discovered that eye-to-eye contact in fact leads to a burst of activity in the reward center of the brain.
    Neuroscientists at University College London asked eight female and eight male volunteers to look at photos of the faces of 40 different people who were either looking at the camera or gazing to one side.
    While the volunteers looked at the pictures, they were given a scan with functional magnetic resonance imaging（磁性共振成影仪器）, which measures increased blood flows to the various parts of the brain and thus provides a "map" of cerebral activity（大脑活动）.
    The volunteers were then asked to rate the attractiveness of each face, and their score was matched against the scan.
    The result: when volunteer had direct eye contact with the face, there was an increase of activity in the ventral striatum（腹面纹状体）, a central part of the brain that anticipates reward or pleasure. But if the eyes did not meet, there was no activity in that brain area at all. The activity increase occurred regardless of the gender of the face in direct eye contact.
    However, there was a bigger-than-usual increase if the person giving the eye was found to be attractive. Activity in the ventral striatum surged. But if the cute person gazed to one side, the ventral striatum remained dormant, apparently disappointed that the stranger was clearly not interested.
    Interestingly, the ventral striatum also perked up if a plug-ugly person gazed to one side, rather than looked at the volunteer right in the eyes.
    Origin of the experiment
    		Romantic novelists like to describe in their writings that two strangers look into each other's eyes across a crowded room and feel the tingle of desire in a special ____71____.
    __72__ of the experiment
    		Investigate whether eye-to-eye contact ____73____ a burst of activity in the reward center of the brain.
     
    Procedure of the experiment
    		◆Ask ____74____ volunteers（8 female and 8 male）to look at photos of the faces of 40 different people who were either looking at the camera or gazing to one side.
    ◆____75____ blood flows to the various parts of the volunteers’ brain and thus provides a "map" of cerebral activity.
    ◆Ask the volunteers to rate the attractiveness of all ____76____,
    ◆____77____ their score against the scan.
     
    ____78____ of the experiment
    		◆As long as the eyes meet ____79____, there must be activities in the brain area. On the other hand, there is no activity at all.
    ◆The activity of the brain is also ___80_____ with the people’s appearance closely.

    Global surface temperatures have increased 0.6—1.2 degrees since the late 19th century. The 20th century’s 10 warmest years all happened within the last 15 years. Of these,1998 was the warmest year on record. The snow covering the Northern Hemisphere（半球）and floating ice in the Arctic Ocean decreased. Globally, sea level has risen 4—10 inches over the past century. World-wide amount of rain and snow over land has increased by about one percent. The number of major rainfall events has increased throughout much of the United States.
    Increasing concentrations（集中）of greenhouse gases are likely to make climate change faster. Scientists expect that the average global surface temperature could rise 1.6—6.3 degrees by 2100，and the climate in different areas could change differently. Evaporation（蒸发）will increase as the climate warms, which will increase average global amount of rain and snow. Soil moisture（潮湿）is likely to decrease in many areas, and strong rainstorms are likely to become more frequent.Sea level is likely to rise two feet along most of the U.S coast.
    Calculations of climate change for certain areas are much less able to be trusted than global ones, and it is unclear whether the climate in different areas will become more variable（变化无常的）.
    64．Which of the following statements is not mentioned in the first paragraph?
    A．The snow has been seen covering the Southern Hemisphere .
    B．More and more major rainfall events have happened to the U.S.
    C．On the whole earth, sea level has risen 4—10 inches.
    D．The amount of the rain in the world has increased by about 1%.
    65．According to scientists, the reason why the climate becomes warm is that________.
    A．the snow covering Northern Hemisphere has decreased
    B．evaporation has increased in the recent years
    C．greenhouse gases concentrate increasingly
    D．the floating ice in the Arctic Ocean has decreased
    66．It is because______ that strong rainstorms become more frequent.
    A．average global little of rain and snow increases
    B．the climate becomes warm
    C．soil moisture decreases
    D．sea level rises two feet

    A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what’s happening in their brains.
    When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons(神经元) are responsible for this processing.
    　　The fMRI (functional Magnetic Resonance Imaging功能性磁共振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
    　　Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize which parts of the brain receive more oxygen- rich blood--and therefore, which parts are working to process information.
    　　An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
    　　The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
    In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly, related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
    　　 51. What is responsible for processing the information sent by your eyes?
    　　A A small region of the brain.
    　　B The central part of the brain.
    　　C Neurons in the brain.
    　　D Oxygen-rich blood.
    　　52. Which of the following statements is NOT meant by the writer?
    　　A Cells in your brain are called neurons.
    　　B The more oxygen a neuron consumes, the more blood it needs.
    　　C fMRI helps scientists to discover which parts of the brain process information.
    　　D fMRI helps scientists to discover how the brain develops intelligently.
    53. "Highlighting the areas of the brain at work" means
    　　A "marking the parts of the brain that are processing information"
    　　B "giving light to the parts of the brain that are processing information"
    　　C "putting the parts of the brain to work"
    　　D "stopping the parts of the brain from working"
    　　54. What did the researchers experiment on?
    　　A Animals, objects, and fruits.
    　　B Two volunteers.
    　　C fMRI machines.
    　　D Thousands of pictures.
    55.What is the best title for the passage?
    A Mind-reading Machine

    B
    Science isn’t something mysterious, only for the few. Every one of us—whether a poet, worker, or physicist has to be able to think scientifically, and to understand some science, such as whether to smoke, what to eat, and what protection to use. Even for decisions that don’t depend on some scientific facts, science remains the proven set of best methods for getting exact information about the world.
    Some people will end up as policy-makers in government or business. People such as these make decisions that affect the life of everyone, and most of them know no more about science than does the rest of the general public. Yet they are called upon to decide what to do about nuclear reactors(核反应堆), global warming, environmental toxins(环境霉素), expensive space programs, and biomedical research. It’s nonscientists, not scientists, who have the last word on whether the milk we drink can safely come from cows treated with medicine. To make such decisions wisely, the decision makers have to be drawn from a scientifically educated public.
    Even if science is irrelevant（不相干的） to the lives of ordinary Americans, a strong scientific spirit is basic to our economy, educational system, and society. This requires lots of young people to become excited enough by science that they decide to become professional scientists. This also requires, to some degree, the support and understanding of the general public.
    Scientists are not always able to communicate their findings in an easy-to-understand manner. Although the scientists should do a better job of explaining what they have discovered, members of the general public have to make efforts to understand what is being said.
    46．What does the author mean by saying that “a strong scientific spirit is basic to the economy, educational system and society”?
    A．School and society should encourage young people to become professional scientists.
    B．The school should only teach lessons of economy and education·
    C．A scientifically educated public is basic to the economy，educational system and society.
    D．More scientists work in our economy, educational system and society.
    47．The general public is required to _______.
    A．support and understand the need of scientific education
    B．check what the scientists are saying
    C．give help to the policy-makers
    D．become professional scientists
    48．The main idea of this passage is _________.
    A．policy—makers must be science professionals
    B．science is not far from everyone’s life
    C．science has nothing to do with ordinary Americans
    D．science professionals make decisions that affect the life of everyone
    49．According to the passage, who can decide whether the milk we drink can safely come from
    cows treated with medicine?
    A．Scientists      B．Young people      C．The public     D．Policy-makers

    It doesn't take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy（烟雾的）day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
    “The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished（减少） lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
    Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person's individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
    Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won't work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”
    66. What does the underlined sentence in the first paragraph mean?
    A. Rocket scientists are making researches on people’s health.
    B. It's obvious that air pollution has a bad effect on people’s health.
    C. People aren't sure whether taking deep breaths on a smoggy day is bad.
    D. People often have a hard time when taking deep breaths on a smoggy day.
    67. The word "vulnerable" in Paragraph 3 probably means _________.
    A. easy to be hurt            B. easy to be protected
    C. easy to be used            D. easy to be saved
    68. The main idea of Paragraph 3  is _________.
    A. that even small risk from particulate causes big problems
    B. that air pollution often leads to heart attack
    C. who are most likely to get affected
    D. that we shouldn't worry about the average low risk
    69. In order to be healthier, you'd better _________.
    A. take deep breaths         B. wear a mask   
    C. live in a countryside       D. clean the busy road
    70. The passage is written in a(n) _________ tone.
    A. subjective         B. humorous     C. doubtful      D. objective

    Zanzibar，Tanzania--Hundreds of dead dolphins were washed up on Friday along the shore of a popular tourist place on Tanzania’s northern coast．Scientists have ruled out poisoning．
    It was not immediately clear what killed the 400 dolphins，whose dead bodies lied along a 4-kilometer coast of Nungwi，said Narriman Jidawi，a marine biologist at the Institute of Marine Science in Zanzibar．But the bottleneck dolphins，which live in deep offshore waters，had empty stomachs，meaning they could have got lost and had been swimming for some time to reorient themselves．They did not die of hunger and were not poisoned，Jidawi said．
    In the US，experts were looking into the possibility that sonar(声呐)from the US submarine could have caused a similar incident in Marothon，Florida，where 68 deep-water dolphins stranded(搁浅)themselves in March 2005．
    The deaths are a blow to the tourism industry in Zanzibar，where thousands of visitors go to watch and swim with dolphins．Villagers，fishermen and hotel residents found the dead bodies and told officials．Mussa Aboud，Zanzibar’s director of fisheries，went on state radio to warn the public against eating the dolphins’meat，saying the cause of death had not been found．
    The Indo-Pacific bottlenose，commonly known as dolphins，are the most common species in Zanzibar’s coastal waters，with bottlenose and humpback dolphins often found in mixed-species groups．
    63．According to the passage，the bottleneck dolphins            ．
    A．are often attacked by submarine in deep water
    B．find it hard to find enough food near the coast
    C．often fall ill along the shore of a tourist place
    D．1ike living in the deep waters near the coast
    64．The underlined word“reorient”means           ．
    A．lose their way                   B．find their way
    C．look for food                        D．fight against enemies
    65．What can we infer from the passage?
    A．The dolphins died because of the sonar from US submarines．
    B．The dead dolphins can not be eaten as they are poisonous．
    C．The US experts are researching sonar at present．
    D．The ability of locating is extremely important for dolphins．
    66．What would be the best title for the passage?
    A．400 dolphins died along the coast of Nungwi．
    B．Dolphins are facing increased risk of death．
    C．It’s necessary for us to protect dolphins．
    D．Nungwi is famous for many dolphins there．
