7．Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world？It's an increasingly urgent question，given the recent mining accidents in Sago．W．Va．and Huntington，Utah．A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work．
Robotic technology，in particular，holds much promise，McAteer says，especially when it comes to mapping mines and rescuing trapped miners-the special operations of the mining industry．
One of the first mining robots was developed five years ago at Canegie-Mellon University's Robotics Institute．It was called Groundhog．It used lasers to"see"in dark tunnels and map abandoned mines-some of the most dangerous work in the business．
The latest design is called Cave Crawler．It's a bit smaller than Grondhog，and even more advanced．It can take photos and video and has more sensors that can discover the presence of dangerous gases．The robot has a real sense of logic，which is hard to believe．If it comes across a thing in the way it gets confused．It has to think through the process and where to go next，and sometimes it  throws a fit just like a real person．
The greatest problem，though，is cost．The money of the earliest research project was provided by the government，but that money has dried up，and it's not clear where future money will come from．Partly for that reason，and partly because of advances in safely，mining is not nearly as dangerous as it was in the past．Since 1990，fatalities（致命性） have declined by 67percent and injuries by 51percent，according to the National Mining Association．
Some experts predict that robots in the mines will serve much of the same function that they do in the automotive industry．The robot do the most boring and dangerous jobs，but don't eliminate the need for human workers．

51．The latest robot is more advanced than Groundhog mainly becauseD．
A．it's a bit smaller
B．it can map abandoned mines
C．it can see in the dark tunnel
D．it has a real sense of logic
52．The underlined phrase"throws a bit"in Paragraph 4probably meansA．
A．gets angry        B．gets sick
C．becomes hungry    D．becomes cheerful
53．We can infer from the last paragraph thatC．
A．robots in mines will serve much in the automotive industry
B．there will be no need for human workers in mines
C．the mine robots will have a very bright future
D．robots in mines only do some simple jobs now
54．We can learn from the text thatC．
A．a mining robots can help miners have an operation
B．Groundhog can discover the presence of dangerous gases
C．experts are trying to make robots help miners with dangerous work
D．robots have helped improve the safety of mining
55．What can be the best title for the text？B
A．Mining Accidents in America
B．Robots in Mines
C．Cave Crawler，the Latest Robot
D．The Future of Robots．

14．Conventional wisdom is a major barrier to innovation（創新）that threatens the survival of companies everywhere．It's based on the assumption that old ideas will always work，so they shouldn't be challenged．While this may be a valid assumption in situations that don't change，it's unlikely to hold true in a changing situation．In today's rapid changing global environment，old methods often don't work，and stubbornly using them can lead to major problems．
Most people seem to agree with conventional wisdom because it gives one a false sense of security．If everyone else believes it，then it must be tree．Individuals who use conventional wisdom are certain that they are right，and being fight is good．They want to continue using old ideas rather than take risks with changes that might not work．In 1977，Ken Olsen，co-founder and CEO of Digital Equipment Corporation（DEC），stated"There is no reason for any individual to have a computer in his home．"Despite being a dominant leader in the computer industry，DEC no longer exists．
People seem to forget that since innovation is a change，there can be no innovation without change．Unfortunately，conventional wisdom prevents leaders，followers and companies from changing and therefore innovating．If companies don't innovate，but their competitors do，the future is likely to be problematic（成問題的）．Breaking from conventional wisdom has led to many of the most innovative companies and products in history across many industries，so it has a powerful effect on business success．
Ted Turner（founder of CNN） knew little，if anything，about the news business，but he knew it was inconvenient to watch news only at the dinner hour，as was common before CNN．Turner's solution was to create a cable （有線的）channel devoted to news 24hours a day．The news establishment reflected conventional wisdom at the time，and predicted his idea would fail because no one wanted to watch the news all day．However，it doesn't take a rocket scientist to understand that viewers don't have to watch the news all day for the CNN to work．Viewers just have to watch when they want to get information．Due to conventional thinking，the critics failed to recognize the opportunity that was clear to Ted．They assumed that only what was familiar to them could work in the future．
Conventional wisdom prevents creativity，flexibility and risk-taking，so unconventional leaders enthusiastically break from it．To survive，boom and maintain competitive advantage，companies must be flexible when reacting to change．
28．DEC has disappeared probably becauseA．
A．the CEO stuck to the conventional ideas
B．the consumers didn't like its products
C．the leaders lacked the sense of security
D．the employees took many risks with changes
29．The founding of CNN is used as an example to proveC．
A．missing opportunities could lead to failure
B．watching news at the dinner hour is convenient
C．changing could contribute to business success
D．conventional wisdom influences business success
30．What does the underlined part probably mean？B
A．Rocket scientists can ensure the CNN works properly．
B．It's easy to know people needn't watch the news all the time．
C．It's necessary to understand when people watch the news．
D．Most of the viewers don't like to watch the news at work．
31．The passage is mainly written to tell us thatD．
A．old methods are changing with time
B．opportunities lead to business success
C．successful companies need wise leaders
D．conventional wisdom limits innovation．
