    Global Positioning Systems 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. 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'.”
    Mister 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 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 These include maps that are outdated, incorrect or difficult to understand.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 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

    B．We should introduce higher standard 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3:What is Mr. Brown’s attitude towards GPS?
    A．UnconcernedB．PrejudicedC．ObjectiveD．Critical
    小题4:What would be the best title for the text?
    A．driving with GPS can be difficult
    B．driving confusions can be caused by small screen
    C．driving without GPS should be much more convenient
    D．GPS equipment in driving: to be deserted or improved?

    In some countries in which there is very little rain at any time, the farmers have to irrigate their fields. Irrigation is easy enough if there is a great river near the crops, and if there is plenty of water in it. Canals carry the river water to the fields when necessary. In some seasons there may be too much water in the river, and the water may flood all the land near it. At other times the river water may not be enough for all the farmers, and then it will be difficult to irrigate the fields.
    To prevent these difficulties, a dam may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land. A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.
    Dams have been built for centuries in different parts of the world. Modern dame are usually built of concrete（混凝土）but earth dams were used in India and Sri Lanka about 2500 years ago. There was another across the River Tigris very long ago, and large numbers of irrigation canals were made in Iraq to irrigate the land. The Romans were great dam-builders and there was also a famous dam at Ma’ rubin Arabia.
    We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.
    小题1:The first paragraph mainly talks about         .
    A．the problems caused by river water
    B．the necessity to irrigate the field
    C．the water shortage in some countries
    D．the canals carrying water to fields
    小题2:A dam is usually built         .
    A．to cover the houses and fields
    B．for people to have the right amount of water at all times
    C．to grow crops better
    D．to form a large lake
    小题3:The underlined word“that”means        .
    A．a dam will be built across the river
    B．a dam will store water for dry seasons
    C．in wet seasons a dam will prevent the flooding of the land
    D．houses and fields will be covered will water
    小题4:The third paragraph suggests that        .
    A．modern dams are made of concrete
    B．Romans once built many great dams
    C．there was too much water in 1rap in the past
    D．modern dams are better than early dams

    One would have to be a fool to overlook (忽视)the importance of using positive(积极的) thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little chemicals and good feelings which will reinforce the positive thoughts.
    For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate (导致)thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.
    It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.
    小题1:We can infer from the passage that         .
    A．positive thinking can cure you of your diseases
    B．positive thinking can easily be generated by anyone
    C．a decline of hormone may cause you to be depressed
    D．a specific chemical reaction is the cause of negative thinking
    小题2:According to the passage, which of the following is true?
    A．Feeling and thoughts can generate each other.
    B．It's easier to control thoughts than to control feelings.
    C．Your success depends wholly on your attitude.
    D．Keeping smiling will surely make you successful.
    小题3:Just like a one-eyed man in the land of the blind, you should             .
    A．control your feeling to what is happening to you
    B．be king in your office
    C．pay no attention to what is going on around you
    D．take positive attitude in the office of militant negativism
    小题4:The best title to the passage is             .
    A．The Bad Effect of Negative ThinkingB．Why Should People Think
    C．Thinking: The Vital WayD．Positive Thinking Benefits People

    Gauri Nanda sees a wearable computer as a handbag — one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.
    That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf.
    Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
    As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
    Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go.
    Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring — and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years — making for a booming market for wearable computers that don’t like something out of science fiction.
    小题1:Which of the following describes a wearable computer?
    A．It can be washed in a washing machine.
    B．It is much heavier than a leather purse.
    C．It can download songs from the Internet.
    D．It is made of clothes conducting electricity.
    小题2:According to the passage, these new wearable computers ________________________.
    A．require users to operate on the stomach
    B．pick up the signals through wires and chip
    C．are being applied in some different areas now
    D．are smarter but more expensive than the old ones
    小题3:What does the underlined sentence in the last paragraph mean?
    A．These new wearable computers have become fashionable.
    B．People would like to learn more about these new computers.
    C．These new wearable computers promise to sell well in the future.
    D．The idea of these purse-like computers comes from science fiction.
    小题4:The purpose of the passage is ________________________________________.
    A．to introduce a new kind of computerB．to explain the function of computers
    C．to compare different types of computersD．to show how high technology affects our life

    Technology is making life easier for some dairy farmers．They use robotic systems to milk their cows．Cows are trained to follow a series of paths that lead to milking stations．Only one cow at a time can enter a station．
    Once inside，the cow is rewarded with food．As the cow eats，a  robotic arm cleans and connects the animal to the milking machine．A few minutes later，milking is complete．The gate is opened，the cow is released and the next cow enters．
    The robotic systems are designed to operate 24 hours a day．The cows get to decide when they want to be milked．Cows are milked an average of about three times a day．Some are milked four to six times a day．
    The cows wear collars around their necks that identify them to the system．A computer keeps records on their eating and milking．A cow is released from the station if the computer decides it should not be milked．
    The automated system also measures the temperature and color of freshly produced milk．Milk is thrown away if it does not pass the tests．
    Professor Plaut believes the systems will appeal（吸引） especially to the next generation of farmers．She means young people who are more interested in technology and less interested in working all the time on the farm．Still，she says the price of robotic milking systems will continue to limit their use．
    Doug and Tina Suhr have more than 100 cows on their family farm．Last year it became the fourth farm in southeast Minnesota to get a robotic milking system．A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars．The second cost 150 000．
    Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot．He says the increase in milk production reaches a high of more than six kilograms per cow per day．
    小题1:From the first paragraph，we can infer________．
    A．the robotic system is designed to reduce labor
    B．cows can be raised by robots in the future
    C．robots direct cows into milking stations
    D．cows are kept clean by robots on some farms
    小题2:Besides milking cows，the robotic system also can______．
    A．adjust the temperature of milking stations
    B．judge the quality of fresh milk
    C．improve the appetite of cows
    D．keep fresh milk for two weeks
    小题3:Why is the robotic system not popular now?
    A．Because young people have no interest in it．
    B．Because it is difficult to learn how to use it．
    C．Because people can’t afford to buy it．
    D．Because it usually causes the waste of milk．
    小题4:According to Doug，what is the wage of an employee?
    A．150 000～170 000．B．750 000．
    C．150 000～30 000．D．30 000—32 000
    小题5:The best title for the passage may be_________．
    A．Letting robot milk your cowB．Milking cows by hand
    C．Improving the quality of milkD．Drinking fresh milk every day

    It’s good to make mistakes, and here is why．
    First of all, mistakes are a clear sign that you are trying new things． It’s always good to try new things because when you are trying new things you are growing． If you never try anything new, how can you improve? How can you expand? The simple answer is “You can’t”． Look around you． With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new．
    Another good thing about mistakes is this: When you are making mistakes, you are learning． Consider this: Edison failed 10,000 times before he perfected the light bulb． When asked how it felt to fail that many times, he said that he hadn’t failed 10,000 times, but rather had learned 10,000 things that didn’t work．
    Finally, when you make a mistake you are much closer to success． Why?
    Because when all is said and done, you will have tried some number of things before you succeeded． Every time you make a mistake you eliminate one of those things and are one step closer．
    But this all doesn’t mean that you should go ahead without considering the consequences of a mistake． Quite the contrary, when you try something new you have to be willing to set some reasonable limits so that in the event that it doesn’t work out the way you want it to, you will be in a position to try again．
    We all have limited resources in the form of time and money so don’t blow them all on one approach to a problem． Realize that it probably won’t be perfect the first time and allocate （分配） these resources appropriately so you can learn, make corrections, and try it again． Only by accepting and using your mistakes in this way can you make significant advances in your business and your career．
    There is an old saying that goes, “If you’re not making mistakes, you’re not trying hard enough．”
    So go forth and make mistakes． And learn． And grow． And prosper（成功）．
    小题1:From the second paragraph, we can conclude that _______．
    A．mistakes are unnecessary for development
    B．we are afraid of trying new things
    C．it’s common for people to make mistakes
    D．mistakes are better than not trying
    小题2:The underlined word “eliminate” means _______．
    A．avoid B．remove C．accept D．solve
    小题3:According to the article, one thing you should pay attention to about making mistakes is   ．
    A．avoiding making the same mistakes
    B．accepting the punishment willingly
    C．taking consequences into account
    D．trying things out one by one
    小题4:What would the writer probably suggest we say to ourselves when we make a mistake?
    A．Never mind, I can always try again．
    B．I’d better stay out of trouble．
    C．Ok! Now I can learn something．
    D．Look at this mess． Anyone would be upset．

    Bamboo（竹） is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
    Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe（欧洲）. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains.
    Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters（厘米）wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
    Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.
    In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields be watered.
    小题1:How is bamboo like grass?
    A．It is thin and easy to cut.
    B．It grows everywhere.
    C．It grows quickly after it’s cut short.
    D．It is short and green.
    小题2:The underlined sentence “while others may grow to more than 30 centimeters across.” means “Some other bamboo plants may grow to be very _______.”
    A．short B．strong C．thickD．tall
    小题3:From the text we know ______.
    A．All people call bamboo plant trees
    B．a bamboo plant may grow 4.5 meters in three days
    C．the bamboo plant changes its colors when it grows
    D．a bridge held by bamboo cable was built thousands of years ago
    小题4:Why did the engineers teach the poor farmers in Africa to make use of bamboo?
    A．Because it is cheap. B．Because it is colorful.
    C．Because it drills fast.D．Because it is used by Asians.
    小题5:Which of the following is NOT true?
    A．There are many different kinds of bamboo with different colors.
    B．Cables made of bamboo can last for over a thousand years.
    C．Bamboo can be used for buildings, bridges and watering projects(工程).
    D．Bamboo plants are able to grow well in any part of the world.
