  The Cave Crawler mining robot

  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 high-profile(引人注目的)mining accidents in Sago, W.Va., and Huntington, Utah.A small group of engineers and robotics experts envision(展望)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-Mellon University's Robotics Institute.It was called Groundhog and it looked like a golf cart.It used lasers to “see” in dark tunnels and map abandoned mines-some of the most dangerous work in the business.

  The latest prototype is called Cave Crawler.It's a bit smaller than Groundhog, and even more advanced.It can take photos and video and has sensors mounted that can detect the presence of dangerous gases.Incredibly, the robot has a real sense of logic.If it comes across an obstacle it gets momentarily 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 biggest obstacle, though, is cost.The original research project was federally funded, but that money has dried up, and it's not clear where future funding will come from.Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past.Since 1990, fatalities have declined by 67 percent, and injuries by 51 percent, according to the National Mining Association.

  Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry.The robots do the most repetitive and dangerous jobs, but don't eliminate the need for human workers.

(1)

The phrase “throw a fit” in the 3rd paragraph probably means ________.

[  ]

A.

get angry

B.

get shocked

C.

become excited

D.

become cheerful

(2)

The latest robot is more advanced than Groundhog mainly because ________.

[  ]

A.

it can map abandoned mines

B.

it's a bit smaller than Groundhog

C.

it can see in the dark tunnel

D.

the robot has a real sense of logic

(3)

We can infer from the last paragraph that ________.

[  ]

A.

the mine robots will have a very bright future

B.

robots in mines will serve much in the automotive industry

C.

there will be no need for human workers in mines

D.

robots in mines have a long way to go

(4)

Which of the following can be the best title of this passage?

[  ]

A.

High-profile mining accidents in America.

B.

Could robots replace humans in mines?

C.

The development of robot.

D.

Cave Crawler, the latest robot.

第一节 阅读理解(共20小题;每小题2分,满分40分)

       阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项,并在答题卡上将该项涂黑。

  Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared (红外线)scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest (害虫)problems.

  Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.

  The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.

1.Plants will emit an increased amount of heat when they are______________.

A. sprayed with pesticides          

B. facing an infrared scanner

C. in poor physical condition        

D. exposed to excessive sun rays

2.In order to apply pesticide spraying precisely, we can use infrared scanning to____________.

A. estimate the damage to the crops  

B. measure the size of the affected area

C. draw a color-coded map         

D. locate the problem area

3.Farmers can save a considerable amount of pesticide by______________.

A. resorting to spot-spraying       

B. consulting infrared scanning experts

C. transforming poisoned rain       

D. detecting crop problems at an early stage

4.The application of infrared scanning technology to agriculture met with some difficulties

_______________.

A. the lack of official support      

B. its high cost

C. the lack of financial support      

D. its failure to help increase production

5.Infrared scanning technology may be brought back into operation because of_____________.

  A. the desire of farmers to improve the quality of their produce

  B. growing concern about the excessive use of pesticides on crops

  C. the forceful promotion by the Department of Agriculture

  D. full support from agricultural experts
