California Gives Green Light to Space Solar Power
Energy beamed down from space is one step closer to reality，now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatt (兆瓦)of power beamed down from solar-power satellites beginning in 2016．But some major chal lenges will have to be overcomed if the technology is to be used widely．
A start-up company called Solaren is designing the satellites，which it says will use radio waves to beam energy down to a receiving station on Earth．
The attraction of collecting solar power in space is the almost uninterrupted sunshine available in eosynchronous(與地球同步的)orbit．Earth-based solar cells，by contrast，can only collect sun．
Light during daytime and when skies are clear．
But space-based solar power must grapple(努力克服)with the high cost per kilogram of launching things into space，says Richard Schwartz of Purdue University in West Lafayette，Indiana， "If you're talking about it being economically viable or power of the Earth，it's a tough go．"he says.
Cal Boerman，Solaren's director of energy services，says the company designed its satellites with a view to keeping launch costs down．"We knew we had to come up with a different，revolu-tionary design，"he says．A patent the company has won describes ways to reduce the system'Sweight，including using inflatable minors to focus sunlight on solar cells，so a smaller number cancollect the same amount of energy．
But using minors introduces other chaHenges，including keeping the solar cells from overhea-ting，says Schwartz．"You have to take care of heat dissipation(散發(fā))because you're now concen-trating a lot of energy in one place，"he says．According to the company's patent，Solaren's solarcells will be connected to radiators to help keep them cool．
Though Boerman says the company believes it can make space-based solar power work，it is notexpecting to crowd out other forms of renewable energy．Laws in California and other states requireincreasing use of renewable energy in coming years，he points out．"To meet those needs，we're go-ing to need all types of renewable energy sources，"he says．

A．Right
B．Wrong
C．Not mentioned
17．Solaren is going to design 200 solar-power satellites．
A．Right
B．Wrong
C．Not mentioned
18．Space-based solar cells could collect solar power only when skies are clear．

19．One advantage of space-based solar power system is that it is economical．
A．Right
B．Wrong
C．Not mentioned
20．Inflatable minors are used to reduce the space-based solar power system．
A．Right
B．Wrong
C．Not mentioned
21．Space-based solar power will rule out other forms of renewable energy sources．
A．Right
B．Wrong
C．Not mentioned
22．Many countries will grant permission for the use of spaced-based solar power soon．
A．Right
B．Wrong
C．Not mentioned
參考答案及解析
16．A[解析]本題給出的信息是正確的，文章第一段中提到"ofpower beamed down from s01ar-power satellites beginning in 2016"說(shuō)明太陽(yáng)能衛(wèi)星會(huì)使用無(wú)線電波從太空發(fā)射能量光束。
17．C [解析]文章沒(méi)有談到這方面的信息，文章在第一段中提到200這個(gè)數(shù)字是關(guān)于"Ihe Pacific Gas and Electric Company buy 200 megawatt(兆瓦)of power beamed down from solarpower satellites beginning in 2016"：從2016年起，太平洋天然氣和電力公司將購(gòu)買200兆瓦的從太陽(yáng)能電站的衛(wèi)星上發(fā)送來(lái)的電力。
18．B[解析]本題給出的信息是錯(cuò)誤的。文章在第三段末尾提到："在地球上的太陽(yáng)能電池只能在白天且無(wú)云的時(shí)候收集陽(yáng)光。"
19．B [解析]本題給出的信息是錯(cuò)誤的。從文章第四段"But space-based solar power must grapple(努力克服)with the high cost per kilogram of launching things into space"：但在太空的太陽(yáng)能工廠必須努力克服的問(wèn)題是：向太空發(fā)射每一公斤的物品都要付出高昂代價(jià)，即成本高的問(wèn)題。
20．A[解析]本題給出的信息是正確的，從文章第五段"A patent the company has won describes ways to reduce the system's weight"我們知道這家公司的一項(xiàng)專利說(shuō)明了降低此系統(tǒng)重量的多種方法。
21．B [解析]本題給出的信息是錯(cuò)誤的。從文章最后一段"it is not expecting to crowd out other forms 0f renewable energy"我們知道它(從太空中獲得的太陽(yáng)能)并不會(huì)擠掉其他形式的可再生能源。
22．C [解析]文章沒(méi)有談到這方面的信息。文章主要圍繞美國(guó)，尤其是加州來(lái)說(shuō)，并沒(méi)有提到其他國(guó)家的情況。
