法。由此可推知，人们可能会寻找新的方法以融入宇宙。故选D。

　　3．Which is the best title for the passage?

　　A．A New Horizons Probe

　　B．NASA's Huge Project

　　C．Pluto, a Controversial Planet

　　D．A Close Approach to Pluto

　　解析：选D　标题归纳题。NASA新视野号探测器飞掠冥王星，这是历史上第一次近距离地观察冥王星，是人类历史上的突破。故"近距离地接触冥王星"作标题最佳。故选D。

　　B

　　Giant kites could supply green energy without the need for taxpayer­funded subsidies (津贴) within years. Kite Power Solutions expects to open the U．K.'s first kite power plant in March 2017 in Scotland. It hopes to roll out the technology onshore and at sea, building systems with the capacity to produce "hundreds of megawatts" of power within the decade. The company believes the technology could reduce the cost of wind energy. And it predicted that kite power would cost so little that developing countries would be more likely to use it to free themselves off polluting carbon­heavy energy sources.

　　A spokesman Ainsworth for Kite Power Solutions said the technology could decrease the cost of offshore wind energy, meeting the need for governments' efforts to reduce carbon emissions. He said the technology was easy to fix and maintain, meaning it could be used in deep water, on floating structures far from shore. "If we do that, it opens up a global deep water offshore wind market，" he said.

　　The technology could control rising CO2 emissions in the developing world, where the need to save money forces people to resort to polluting technologies such as diesel. The company has tested the technology on a small scale in Essex and will move its headquarters to Glasgow to prepare for next year's launch. It has won planning permission for a 500 KW demonstration system.

　　The U．K.'s green energy trade body, RenewableU.K., welcomed the technology but warned it was not a_silver_bullet. The deputy chief executive Maf Smith said，"This is an ambitious project to develop wind power at extraordinary heights and it shows the level of new ideas within the renewable industry. Kite power is at an early stage of development and it will take time to see how the technology progresses. Anyway, we will need a wide range of energy sources in the future to meet our needs in an environmentally friendly way."

　　语篇解读：本文主要介绍了风筝发电这项新技术的优势，即成本低、易于安装和维护等，但有人提出相反观点。所以依靠风筝发电技术解决我们的能源需求问题仍有很长的路要走。

　　4．What is the most important advantage of kite power?

　　A．Its low costs.　　　　 B．Its high qualities.

　　C．Its great usefulness. D．Its wide using areas.

解析：选A　细节理解题。根据文章第一段最后两句"The company believes the technology could reduce the cost of wind energy. And it predicted that kite power would cost so little that ..."可知，风筝发电最重要的优点是成本低。故选A项。
