Question

Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable wind energy produced by man-made technologies.

One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity.

According to Pradhan’s proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.

Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains.

T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track.

A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province.

Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn’t taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device.

We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

1.What can we learn about T-Box?

A. It will be fitted on the trains.

B. It is based on Pradhan’s idea.

C. It can turn electricity into light.

D. It was invented by an Indian scientist.

2.How much electricity can be produced per day by T-Boxes along a railway track of 100km?

A. 260 KWH.        B. 2.6 KWH.

C. 150 KWH.        D. 1.5 KWH.

3. It can be concluded from the last two paragraphs that ______.

A. T-Box has proved to be effective in harvesting wind

B. the maintenance of T-Box will be costly

C. there is much to do about T-Box

D. T-Box will come into use soon

4.According to the passage, which of the following statements is TRUE?

A. The Indian inventor Santosh Pradhan invented the speeding train.

B. The T-Box’s design won a silver medal in Lite-On Awards last year.[来源:Z

C. Rail travel has become one of the energy-efficient technologies in the world.

D. The India harvests 10,000 megawatts of electricity each day on average.

5.The passage is mainly written to _______.

A. encourage more people to travel by train

B. explain the advantages of electricity

C. tell readers how to save energy and money

D. introduce a new invention to readers

Answer

1.B

2.A

4.B

5.D

【解析】

试题分析：本文介绍一种新的绿色能源，可以让我们的出行变得更环保和更有效。

1.B 考查细节理解题。根据第三段提到According to Pradhan’s proposal, with a few small improvements in existing trains running in Mumbai,这是基于Pradhan’的建议，故选B项。

2.A 考查细节理解题。根据第五段提到According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track.和第六段提到Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day可知是2.6乘以100，故选A项。

3.C 考查推理判断题。根据倒数第二段提到Though the figures look impressive, it is important to remember that the design is still at a conceptual stage虽然这个数字是很可观的，但要记住这个设计处在概念阶段，故还有很多工作要做，故选C项。

4.B 考查推理判断题。根据倒数第三段提到The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province.可知这个设计在去年的光宝创新奖获得银奖，故选B项。

5.D 考查推理判断题。通过最后一段提到We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.我们期望着看到更多的绿色能源，所以可知本文介绍的一种新的能源给读者， 故选D项。
