    A friend of mine met with an accident driving in darkness. His legs were so hurt that he couldn’t move. What was the   1  was that he found himself unable to ask for help—his mobile phone went out of   2   as a result of exhausted battery (无电) . Nothing could be done but to   3   in cold wilderness (荒野). It was eight hours later that day broke, and then   4   of the rescue (援救).
    It is almost   5   that he could stand （忍受）the horror in the darkness for so long. Even more surprising was his   6  : “First of all, I checked up my   7     conditions and found myself not in mortal (致命的) danger. As there was no   8   to call for help, I leaned back in my seat trying my best to keep the wound from   9  . In this way I dozed (瞌睡) off.”
    His story put an end to my regret (遗憾) for the   10   of an exploration adventure (探险) that happened last year. A group of young men   11   to explore a mountain cave and got lost.   12   to find a way out in the dark cave they were frightened and ran anxiously without a sense of   13  . Finally they felt dead in fear and exhaustion. According to the   14   people that found them, the place where they got lost was only about 10 meters away from the   15   of the cave. If they stayed on the spot when they lost their way and tried to   16   themselves, they would probably sense a faint light glimmering (闪烁) not far away.
    Don’t you think you can compare it with   17   itself? When you meet with difficulty in life and work, you are lost in darkness.   18   you it’s unclear yet and you needn’t put up struggle   19 . It seems to be a negative （消极）attitude,   20   a person who can afford to do so must have foresight (远见) as well as a great courage in the first place.

    试题分析：当你的一生中遇到困难时，在黑暗中迷失了方向，在状况还没有搞清楚之前，你先不要急着去挣扎，这看起来是一种消极的态度，但是能够做到这一点的人必需要有远见，并且在一开始就要有极大的勇气。
    小题1:此处突出强调状况之“糟”。他动不了，更为糟糕的是他不能求救。选B
    小题2:因为电池用尽，手机不能用了，go out of work意为“不工作”。out of service当“停止服务”讲，out of order当“混乱”讲。选D
    小题3:此处表示除了“等”之外，别无选择。此处是固定句型nothing can be done but do, 相当于have no choice but to do从作者叙述的朋友在深夜受伤但非常镇静这一事实可知其他动词不合题意。选C
    小题4:从后文看，作者的朋友最终获救了，因此此处应是援救“到来”了。“耽误”不合题意，因为作者已经说明朋友没有办法呼救;此处作者强调的也不是“成功”。选D
    小题5:在黑夜里如此长时间忍受恐惧，作者认为这是令人“无法想象的”。作者此处是在赞扬朋友在那样的情况下能如此镇静，其他选项不合题意。选B
    小题6:这是指朋友后来的“解释”。从后文可以排除其他选项，此处不是朋友的“借口”，更不是“计划”和“决定”。选C
    小题7:在受伤的情况下，检查的应是“身体的”状况，后面“没有生命危险”也印证了这一点。“精神的”，“工作的”，“医疗的”在此都不合语境。A
    小题8:此处指做事情的“方式”，应用way,指没有办法呼救。method多表示解决问题的具体“方法”。如：his studying method。B
    小题9:因为朋友在车祸中受了重伤，又没法“呼救”，因此应实施自救，阻止伤口“流血”。D
    小题10:从后文可知，探险“失败”了。loss的意思是“损失”，不合题意。B
    小题11:探险没有成功，因此此处只能是“尝试”去做。manage to do sth. 表示“设法干成了某事”，与整个事情的结局矛盾。C
    小题12:从后文“这群年轻人乱作一团”可知，他们找不到出口。其他选项“决心”，“愿意”等不合逻辑。B
    小题13:由这群年轻人迷路可知，他们乱跑一气，没有了“方向”感。D
    小题14:发现年轻人失败真相的应是“营救”人员。由具体的语境可排除其他选项，此处不是指“当地的人”，作者强调的也不是“勇敢的人”。A
    小题15:从后面“亮光闪烁”可知，这儿指的是“出口”，故用opening。C
    小题16:作者强调的就是人们处于危急或困境时应“保持镇静”，故用calm。D
    小题17:作者由上述两个事例联想到“生活”。life意义最具有概括性。作者把上述的经验和教训与人们的实际生活联系起来，其他选项都太片面。C
    小题18:mind sb. 当“提醒某人”讲。处于迷茫状态时，你应该提醒自己情况不明朗，不要轻举妄动。watch“注视、监视”;imagine“想象”不合题意;warn“警告”语气太强，用在此处也不合适。A
    小题19:作者强调人们在处于危急或困境时应“保持镇静”，不要轻举妄动，因此不必“立即”去斗争。其他副词都偏离了作者所表达的中心。B
    小题20:前后文构成的是转折关系。这种态度似乎是消极的，但却表现了一个人的智慧和勇气。理顺了上下文的逻辑关系，就能排除其他选项的干扰。C
    点评：本文介于记叙文和议论文之间，要注意故事发展的细节，注意上下文串联和语法分析，因为在本文中语法分析题考查较多。注意各种小词的辨析。

    下面文章中有5处（第61-65题）需要添加小标题。请从以下选项（A、B、C、D、E和F）中选出符合各段意思的小标题，选项中有一项是多余选项。
    A．Structure of a hurricane
    B．Preparing for a Hurricane
    C. How Hurricanes Move
    D. How Hurricanes start
    E. Hurricane Names
    F. Hurricane Damage
    Hurricanes
    Hurricanes are gigantic tropical storms that can be hundreds of kilometers wide. They bring along very strong winds and a lot of rainfall. They often cause flooding near the coasts and sea levels rise.
    1. __________________________
    Hurricanes are born over tropical oceans, usually during late summer and early autumn. They need two things to get them started: heat and moist air. During the summer the ocean surface heats up and warm moist air starts to rise. Cool air sinks down to replace it. This creates an area of low pressure. The rotation of the earth creates winds around the center of such a low-pressure area. In the northern hemisphere the air moves counter clockwise, in the southern part clockwise. Such a system is called a cyclone. When warm air rises, it cools and creates clouds. Soon, thunderstorms form and it starts to rain.
    All hurricanes begin as cyclones but not all cyclones become storms or hurricanes. Some die out a few days after they start. They don’t have enough energy to become a hurricane. When winds are stronger than 119 km an hour a storm officially becomes a hurricane.
    2. __________________________
    The center of a hurricane is called the eye, a calm area with little rainfall. It is about 30 to 50 km wide. Inside the eye the sea can rise up to one meter because the air moves up. The eye wall is around the eye. This is an area of thunderstorms, rain and the strongest winds—up to 300 km an hour. Then come long bands of rain clouds that are curved towards the center of the hurricane.
    3. __________________________
    In the northern hemisphere hurricanes normally move in a westward direction and then they turn north and northeast. Their path takes them away from the warm tropical water of the equator. When hurricanes move over colder water or over land they lose a lot of their energy. They slow down and as time goes on, they disappear. In the southern hemisphere their path leads them to the south and southeast.
    4. __________________________
    When a tropical storm forms over the Caribbean Sea it gets a name. Every year the first storm of the season is given a name that starts with the letter A, the second storm gets a name starting with B and so on. Years ago only women’ s names were used for tropical storms. Today male and female names alternate –for example, the first storm is named Alexandra, the second one Billy, then Catherine etc. Each year new names are used so that you can connect a storm to a certain year.
    5. __________________________
    Hurricanes are causing more and more damage throughout the Gulf Region, mainly because the population is constantly growing. Many things can be done to protect yourself and your property during a hurricane: Keep emergency supplies of food and water; keep a battery-powered radio ready in case the power goes out. Listen to the instructions you get; keep the gas tank of your car full, in case you have to leave quickly; protect your house by nailing plywood over the windows and doors. Tie down loose objects; find out which roads are best to take you away from the storm; leave your house as soon as you are ordered to evacuate, etc.

    Cell Phones Are the New Cigarettes
    When you get in your car, you reach for it．When you’re at work, you take a break to have a moment alone with it．When you get into a lift, you play with it．
    Cigarettes? Cup of coffee? No, it’s the third most addictive thing in modern life, the cell phone．And experts say it is becoming more difficult for many people to curbtheir longing to hug  it more tightly than most of their personal relationships．
    With its shiny surface, its smooth and satisfying touch, its air of complexity, the cell phone  connects us to the world even as it disconnects us from people three feet away．In just the past  couple of years, the cell phone has challenged individuals, employers, phone makers and  counselors（顾问）in ways its inventors in the late 1940s never imagined．
    The costs are becoming even more evident, and I don’t mean just the monthly bill．Dr．Chris  Knippers, a counselor at the Betty Ford Center in Southern California, reports that the overuse of  cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality．
    Sounds extreme, but we’ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him．
    Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?
    Jim Williams, an industrial sociologist based in Massachusetts, notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation．He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with．Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don’t have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says．
    If the cell phone has truly had these effects, it’s because it has become very widespread．Consider that in 1987, there were only 1 million cell phones in use．Today, something like 300 million Americans carry them．They far outnumber wired phones in the United States．
    小题1:Which of the following best explains the title of the passage?
    A．Cell phone users smoke less than they used to．
    B．Cell phones have become as addictive as cigarettes．
    C．More people use cell phones than smoke cigarettes．
    D．Using cell phone is just as cool as smoking cigarettes．
    小题2:The underlined word “curb” in Paragraph 2 means ____．
    A．rescueB．ignoreC．developD．control
    小题3:The example of a woman talking on the phone in the car supports the idea that           ．
    A．women use cell phones more often than men
    B．talking on the phone while driving is dangerous
    C．cell phones do not necessarily bring people together
    D．cell phones make one-on-one personal contact easy

    The UK's education system is ranked（排列） sixth best in the developed world, according to a global league table published by education firm Pearson in October,2012.
    The first and second places are taken by Finland and South Korea.The rankings combine international test results and data such as graduation rates between 2006 and 2010.
    Sir Michael Barber, Pearson's chief education adviser, says successful countries give teachers a high status and have a "culture" of education.
    International comparisons in education have become increasingly significant - and this latest league table is based upon a series of global test results combined with measures of education systems, such as how many people go on to university.
    The two education superpowers - Finland and South Korea - are followed by three other high-performing Asian education systems - Hong Kong, Japan and Singapore.
    The UK is then only ranked at the head of an above-average group including the Netherlands, New Zealand, Canada and Ireland.
    These are ahead of a middle-ranking group including the United States, Germany and France. At the lowest end are Mexico, Brazil and Indonesia.
    These comparisons draw upon tests that are taken every three or four years, in areas such as maths, science and literacy - and so present a picture lagging by several years.
    Looking at education systems that succeed, the study concludes that spending is important, but not as much as having a culture that is supportive of learning.
    It says that spending is easier to measure, but the more complex impact of a society's attitude to education can make a big difference.
    The success of Asian countries in these rankings reflects the high value attached to education and the expectations of parents. This can continue to be a factor when families migrate to other countries, says the report.
    Looking at the two top countries - Finland and South Korea - the report says that there are many big differences, but the common factor is a shared social belief in the importance of education and its "underlying moral purpose".
    小题1:What’s the main idea of the passage?
    A．The two different education superpowers
    B．The result of one report about education system .
    C．The UK's education system is worst.
    D．Finland and South Korea’S education system
    小题2:According to Sir Michael Barber, Hong Kong’s education system is ranked       in the world.
    A．2ndB．3rdC．4thD．5th
    小题3:All of the following statements is NOT true EXCEPT ________.
    A．At the lowest end are Mexico, Brazil and Indonesia.
    B．Education firm Pearson is disappointed at The UK's education system.
    C．The United States’ education system is one of the best.
    D．There are many big differences in Finland and South Korea.
    小题4:What does the underlined phrase “comparisons” in Paragraph 4 probably mean?
    A．比较B．结果C．研究D．考试
    小题5:What’s the common factor about the education system at the two top countries?
    A. The shared social belief in the importance of education and its "underlying moral purpose".
    B. The developed economy.
    C The high value attached to education and the expectations of parents.
    D. Having a culture that is supportive of learning.

    I come from a city on the United States’east coast. It’s a ten-hour flight for me to get home from Shanghai. When I got off the plane, I took photos of the blue sky and white clouds along the way. After two weeks, I returned to Shanghai. Much to my surprise, the blue sky in Shanghai that I liked before was not as blue as that in the US. I couldn’t help wondering what had happened.
    A few days later, I went to tour Waitan (a famous tourist attraction in Shanghai) by the Huangpu River with some of my friends. There we saw five Ferrari sports cars by the side of the road. The red and yellow cars looked so nice that everyone was looking at them. However, when I turned my head, I noticed the sky over Waitan, I was shocked to find that the buildings in the Lujiazui area on the other side of Huangpu River could hardly be seen. It was then that I realized that Ferrari cars could be bought with money, but a blue sky couldn’t.
    Shanghai is an important economic (经济的) and trade center in China. It has made great contributions (贡献) to the whole nation’s economic development. However, we need to protect the environment during economic growth. Pollution is poisoning our air and our rivers. Without clean air and rivers, how will people be able to survive?

    Mars Was Not Always Bitterly Cold
    Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today.  The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.
    The Caltech scientists say carbonate（碳酸盐） minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（陨石） that had its beginnings near the Martian surface.
    Today, the average temperature on Mars is sixty-three degrees below zero Celsius.
    The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information.
    Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth.
    The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home."
    小题1: The underlined word “establish” in Paragraph 1 probably means “___________”.
    A．to set up
    B．to make people accept a belief
    C．to discover or prove
    D．to start having a relationship with others
    小题2:How did the scientists reach the finding?
    A．By studying Allan Hills meteorite.
    B．By using spacecraft orbiting Mars.
    C．By studying minerals gathered on Mars
    D．By studying a meteorite on the Martian surface.
    小题3:According to the fourth paragraph, what have spacecraft orbiting Mars done?
    A．Measuring the temperature of Mars.
    B．Taking photos of the surface of Mars.
    C．Confirming that there is water flowing on Mars.
    D．Finding where human beings will probably land on Mars.
    小题4:How did Allan Hills meteorite get its name?
    A．From its original place on Mars.
    B．From where it was found on the earth.
    C．From the name of the scientist who found it.
    D．From the name of the aircraft that discovered it
    小题5: Where can we most probably read this passage?
    A．In a biography of scientists.
    B．In a geography magazine.
    C．In an environment report.
    D．In a science report.

    Pingyao, located (坐落于) in the center of Shanxi Province, is a famous historic cultural city of China and a world cultural heritage (遗产) site. It is 90 kilometers south of Taiyuan on the Fen River.
    People lived in Pingyao during the New Stone Age. Its long period as a county government seat (县衙) has left Pingyao with lots of historic buildings and sites, with a 2,700-year history. Ninety-nine of them are under government protection, including Zhengguo Temple, Shuanglin Temple and Pingyao Ancient City.
    During the Ming and Qing Dynasties, businessmen organized commercial (商业的) groups that did business nationwide. Shanxi Province had some of the most important ones and Pingyao was their center. In 1823, a store, known as Rishengchang (Sunrise Prosperity), traded in bank checks (支票) rather than in silver or gold coins. It was the beginning of modern Chinese banking. Branch (分支) banks were soon set up in major cities in China and other parts of Asia, leading to great development in Pingyao. Its lacquer ware (漆器) became well known as well.
    In Pingyao Ancient City are many traditional houses and commercial buildings, 3,797 of which are protected and more than 400 of which are in good condition. Not only do the houses in Pingyao show Shanxi’s history and culture, but this large number is valuable for studying its history, customs, ancient buildings and art. Most of these houses are still used as homes and shops of local people.
    In 1997, Ancient Pingyao City was listed in World Heritage List as “World Culture Heritage Site”(世界文化遗产).
    小题1:What does the underlined word “them” (in Paragraph 2) refer to?
    A．Historic buildings and sites.B．The three temples.
    C．The county government seats.D．The 2,700-year history.
    小题2: Which of the following about Pingyao is NOT mentioned in the passage?
    A．Its location.B．Its tourism.C．Its business.D．Its history.
    小题3:During the Ming and Qing Dynasties, Pingyao was a leading center in _____.
    A．growing rice and corn .B．raising cattle.
    C．commercial trade.D．making gold coins.
    小题4:If you want to know about the history of banking in China, which of the following places should you visit?
    A．Sunrise Prosperity.B．Zhengguo Temple.
    C．A lacquer ware store. D．A commercial house.

    Now let’s look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved(进化) through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way.
    In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species.
    For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled.
    Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities.
    小题1:From the passage we can infer that in the course of evolution _______.
    A．humankind is very important to earlier species, such as the primate group
    B．human beings are limited by the environment while animals are not
    C．human beings become more and more different from each other
    D．humankind has experienced a generalization rather than specialization in ability
    小题2:According to the passage, primate includes such animals as _______.
    A．monkeys and anteatersB．tigers and apes
    C．apes and monkeysD．monkeys and giraffes
    小题3:According to the passage, evolution has made it possible for humans to _______.
    A．increase the population
    B．resist natural offers
    C．go to the moon
    D．cure all diseases
    小题4:According to the author, imbalance between biological potential and environ mental resistance has resulted in _______.
    A．the population explosion
    B．the destruction of human habitations
    C．the growth of natural ecosystem
    D．the specialization of humans

    When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
    One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
    But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
    To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
    Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.
