In 2007, the first solar electric boat crossed the Atlantic Ocean. Now a Swiss group wants to cover that distance and keep going, circling the globe on nothing but the sun’s power for the first time.
The team of engineers and scientists has started the building of its 98-foot long boat, named Planet Solar, in Kiel Germany. The boat’s power will come from the 5,000 square feet of solar panels(电池板), about the size of two tennis courts, covering its broad deck. When the sun is shining bright above, they will turn 23 percent of the sun’s rays to energy — six percent more than average solar panels.
Even though batteries aboard Planet Solar can store enough energy to power it through up to three days of cloudy weather, the sailors will try to avoid clouds: constant communication with the French meteorological institute, Meteo France, will help the sailors stay with the sunny course.
The $11.5 million project, which is led by Raphael Domjan, should be ready for its first voyage next summer. The solar electric boat will warm up in European waters, and attempt to deal with traveling around the globe in spring 2011. At a maximum speed of 16 mph, Planet Solar will be the fastest solar electric boat. The team expects to finish the first leg of its journey across the Atlantic in about two weeks, compared to the six months the solar boat took back in 2007.
If sailing by sun becomes practical, it would be a return to the green boating methods of the days of Christopher Columbus. Those long-ago voyages relied only on a different type of renewable energy: wind. And, if wind-powered sails could be combined with solar panels, we might really pick up the boating speed.
57. Which of the following is NOT true about Planet Solar?
A. Its deck is covered by solar panels.
B. It will be the fastest solar electric boat.
C. It is 98-foot long and is to be made in Germany.
D. It can turn 17 percent of the sun’s rays into energy.
58. Planet Solar will be likely to __________ in continuous rainy weather.
A. continue traveling forward
B. ask the local weather station for help
C. stop to wait for the weather to clear up
D. turn to Meteo France for help to choose the sunny course
59. What can be inferred from the passage?
A. Sailing by solar energy has not been widely used in today’s green boating.
B. Planet Solar will be the first boat to circle the globe using solar energy in 2011.
C. The solar panels in Planet Solar can turn more sunlight to energy than average ones.
D. Batteries aboard Planet Solar can be consumed for at most three days of cloudy weather.
60. What is the main idea of the passage?
A. Planet Solar uses solar energy all over the world.
B. Planet Solar aims to be the first to circle the globe.
C. Planet Solar collects a different kind of renewable energy.
D. Planet Solar combines traditional methods with modern technology.

In a world with limited land, water and other natural resources(资源), the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable(可持续的)ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.
Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to made full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high  targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers a large of new chances for sustainable product industries.
【小题1】The traditional business model is harmful because of all the following EXCEPT that____.

A.it makes the world warmer
B.it consumes natural resources
C.it brings severe damage to future
D.it makes growth hard to continue
【小题2】What can we infer from Paragraph2?
A.China lacks wind and solar energy
B.China is the leader of the low-carbon market
C.High-speed trains are a low-carbon development
D.Palm oil is made at the cost of valuable forests
【小题3】To fully develop the low-carbon markets, governments can______.
A.cut public expensesB.forbid carbon emission
C.develop public resourcesD.encourage energy conservation
【小题4】We can learn from the last paragraph that business have many chances to _______.
A.develop sustainable productsB.explore new natural resources
C.make full use of natural resourcesD.deal with the major challenge
【小题5】What is the main purpose of the passage?
A.To introduce a new business modelB.To compare two business models
C.To predict a change of the global marketsD.To advocate sustainable development

As the railroads and the highways shaped the American West in the past centuries, a new electhical generating(发电)and transmission(输送)systen for the 21th century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the suurouding community. The same is true of big solar ppants and the power lines that will be laid dowm to move electricity around.
The 19th century saw land grants(政府拨地)offered to railroad companies to build the transcontinental railroads ,leaving public land in between privately owned land . In much of the west ,some of the railroad sections were developed while others remained undeveloped ,and in both cases the landownership has presented unique challenges to land management ,with the completion or the interstate highway system ,many of the small towns which sprang up as railway stops and developed well ,have lost their lifeblood and died .
Big solar plants and their power lines will also have effects far beyond their direct footprint in the west .this is not an argument against building then ,we need alternative energy badly .and to really take advantage of it we need to be able to move electricity around far more readily than we can now .
So trade-offs will have to be made .some scenic sport will be sacrificed .some species (物种)will be forced to move ,or will be carefully moved to special accommodations ,deals will be struck to reduce the immediate effects .
The lasting effects of these trade-offs are another matter .the 21st century development of the American west as an ideal place for alternative energy is going to throw off a lot of power and money to do a lot of good .but it is just as likely that they will be spent wastefully and will leave new problems behind ,just like the railroad and the highway .
The money set aside in negotiated trade –offs and the institution that control  will shape the west far beyond the immediate footprint of power plants and transmission lines .so let’s remember the effects of the railroad and the highways as we construct these new power plants in the west .
【小题1】
what was the problem caused by the construction of the railways ?

A.small towns along the railways became abandoned .
B.some railroad stops remained .
C.land in the west was hard to manage .
D.land grants went into private hands.
【小题2】
what is the major concern in the development of alternative energy according to the last two paragraphs ?
A.the transmission of power B.the use of money and power
C.the conservation of solar energyD.the selection of an ideal place
【小题3】
what is the author ‘s attitude towards building solar plants ?
A.cautious B.approving C.doubtful D.disapproving
【小题4】
which is the best title for the passage ?
A.how the railways have affected the west
B.how solar energy could reshape the west
C.how the effects of power plants can be reduced
D.how the problems of the highways have been settled
