    　　Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in this world?A small group of emgineers and robotics experts picture a day in the not-too-distant future when robots and other technology do most of the dangerous mining work．

    　　One of the first mining robots was developed five years ago at Carnegie-Mdllon University’s Robotics Institute．It was called Groundhog and it looked like a golf cart,．It used lasers(激光)to“see”in the dark and map given up mines-some of the most dangerous work in the business．

    　　The latest model is called Cave Crawler, It’s a bit smaller than grouondhog．and even more Advanced．It can take photos and videos and has sensors that can discover the presence of dangerrous gasses．Amazingly．the robot has a real sense of logic(逻辑性)．If it comes acorss something difficult, it gets monentarily punded．It has to think about what to do and where to go next．Sometimes it throws a fit just like a real person．

    　　Myles and his colleagues hope that robots like Cove Crawler will one day be used in rescue(营救)operations“A robot could speed up the rescue process by doing discovery(侦察),”says Chuck Whittaker, a roboties engineer at Carnegie-Mellon．“The robot can go ahead and, with its sensors, report what it has found and whether jit is safe for humans to proceed．”

    　　Using robots in rescue operations, though, is probliematic, The lasers that guide the robots don’t work in smoky environments so the engineers at Carnegie Mellon have experimnted with sonar(声纳)and radar guidance systems, and with some success．

    　　Some experts predict that robots do the most repetitive and dangerous jobs, but won't get rid fo the need for human workers．

    (1)

    The underlined phrase“throws a fit”in Paragraph 3 probably means ________

    [　　]

    A．

    gets angry

    B．

    gets shocked

    C．

    becomes confused

    D．

    becomed cheerful

    (2)

    The latest robot is more advanced than Groundhog mainly because ________

    [　　]

    A．

    it can map given up mines

    B．

    it can see in the dark tunnels

    C．

    it’s smaller than Groundhog

    D．

    it has a real sense of logic

    (3)

    Which of the following is true according to the passage?

    [　　]

    A．

    Mining robots do most of the mining work at present．

    B．

    Groundhog can discover the persence of dangerous gases．

    C．

    Experts are trying to make robots save miners in danger．

    D．

    robots can work in smoky areas with the help of a laser．

    (4)

    We can infer from the last paragraph that ________

    [　　]

    A．

    the mine robots will have a very bright future

    B．

    robots in the sutomotive industry must be improved

    C．

    there will be no need for human workers in mines

    D．

    robots in mines will cost a lot
