阅读田纳西河流域的综合开发与治理示意图,完成问题。

小题1:田纳西河流域管理局(TVA)在“统一管理,综合开发”的过程中,将下列哪个因素作为流域开发的核心(    )

A.河流的梯级开发                       B.河流的洪涝治理  

C.流域内农业的多种经营                 D.流域内的矿产开发

小题2:提高库区水质的有效措施有(    )

A.大力发展旅游业

B.水源涵养林的保护

C.沿岸禁止工业的发展

D.大力发展养殖业

答案

小题1:A

小题2:B

本题考查田纳西河流域的开发。

小题1:河流的梯级开发是流域治理开发的核心。

小题2:田纳西河流域早期开发中,农业一直占据着主导地位,这里是亚热带地区,气候温暖湿润,非常有利于棉花的种植。由于长期的过度垦殖,加上滥伐森林和经常性的暴雨,田纳西河流域土地退化、水土流失现象严重。故提高库区水质的主要措施是水土保持林的建设。

     A car that runs on coffee is unveiled (shown to the public for the first time) today but at between 25

and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants.

     Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400

and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future. The

car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules

(颗粒). It has been built by a team from the BBCI science programme Bang Goes The Theory and will go

on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can

power vehicles.

     The team calculates the Carpuccino will do three miles per kilo of ground coffee (咖啡粉)-about 56 cups

of espressos (浓咖啡) per mile. The journey will use about 70 kilos of ground coffee which, at supermarket

prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £l,820,

or between 25 and 50 times the £36 cost of petrol for the journey. In total, the trip will cost 11,760 espressos,

and the team will have to take 6coffee breaks' roughly every 30 to 45 miles to pour in more granules. They

will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which

is also generated by the process. So despite a top speed of 60 mph, the many stops mean the going will be

slow, with the journey taking around ten hours.

     Sadly, the inventors will still have to pay duty on their coffee fuel-even though tax collectors at Her

Majesty's Revenue and Custom haven't yet worked out how much.

     Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon

content so you can use it as a fuel. The coffee needs to be very dry and in granules to allow the air to move

through the pile of coffee as it burns. The brand doesn't matter." He said the same technology could be used

to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste.

1. Which is the right way to choose the coffee used as fuels to run the Car-puccino? [ ]

A. It should be very dry.

B. The stronger, the better.

C. The smaller the granules are, the better.

D. It should be of a certain brand.

2. What can be inferred from the passage? [ ]

A. All kinds of materials can be used as fuels.

B. The Car-puccino will be put into the market soon.

C. Nick Watson is the designer of the Car-puccino.

D. Much remains to be improved for the Car-puccino.

3. The Car-puccino has its disadvantages EXCEPT that _____. [ ]

A. it makes a lot of noise

B. it runs at a very high cost

C. it has to stop to be refueled very often

D. it's not good enough for long-distance journey

4. How much ground coffee will be used to cover a distance of 126 miles in this car? [ ]

A. About 70 kilos.

B. About 42 kilos.

C. About 32 kilos.

D. About 30 kilos.
