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 【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.

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

【答案】

【1】B

【2】A

【3】C

【4】B

【5】D

【解析】

试题分析:

【1】细节理解根据文章第三段中的内容,结合第二段中所写的According to Pradhan’s proposal。可知这个T-Box的理念是以Pradhan’s 的提议为基础的。应选B。

【2】数字计算根据文章第五段around 150 T-Boxes can be fitted along a 1,000-meter railway track以及第六段中的150 T-Boxes can produce 2.6 KWH of electricity per day,可计算出应选本题选A。

【3】细节理解根据文章写最后两段中所表述的内容可知作者是在讲述T-Box这种设备的一些问题和前景,故本题应选C。

【4】细节理解根据文章第六段中的The T-Box’s design won a silver medal in last year’s Lite-On Awards,可知B选项的意思与之一致。故选B。

【5】写作目的通读全文,文章主要介绍了T-Box这种新发明,故选D。

Tips for Cycle Trips

Cycling has many advantages as a form of travel, as it is the fastest way to travel by human Power, and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation.

Distance

On level terrain(地形),without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80-100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities.

Geography

The gradient(坡度)of the trip will reduce your range.A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time.In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill.A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass.However, it is worth bearing in mind that the most scenic routes often come from hilly terrain.

Eat

Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns-there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises.

Sleep

While you can take a tent with you, many hotels and especially campsites can accommodate cyclists. However, there are also some hotels that may be less used to accommodating cyclists.If you are exploring an unfamiliar world, asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.

【1】Which distance does the author suggest to ordinary cyclists a day?

A.50km. B.90km.

C.130km. D.250km.

【2】Form the passage, we can learn that_____________.

A.high quality food is easy to get on long trips

B.hotels seldom provide accommodation for cyclists

C.cycling over a mountain is challenging but worthy

D.it takes cyclists 15 minutes to climb 100m of altitude

【3】We can probably read this passage in___________.

A.a geography book B.a research report

C.a science fiction D.a travel magazine

【题目】Recently some American scientists have given a useful piece of advice to people in industrialized countries.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.1

The scientists say that human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this has led to new kinds of sicknesses.2They are called“diseases of civilization”.Many cancers and diseases of the blood system are examples of such diseases.

The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.3However, a change in food is one of the main differences between life in ancient times and that today.

Stone Age people hunted wild animals for their meat, which had much less fat than domestic (驯养的) ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains. 4 We eat six times more salt than our ancestors and we eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.

5But the scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fat, salty and sweet food.

A. Stone Age people lived a simple life without any meat.

B. But today, we enjoy eating a lot of these.

C. In that case, they would live a much healthier life.

D. Ancient people also got lots of physical exercise.

E. These new sicknesses were not known in ancient times.

F. People today probably don't want to live like our ancestors.

G. Modern people used to suffer from“diseases of civilization”.
