　　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 youre talking about it being economically viable or power of the Earth，its a tough go．"he says.

　　Cal Boerman，Solarens 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 systemSweight，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 youre now concen-trating a lot of energy in one place，"he says．According to the companys patent，Solarens 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，were go-ing to need all types of renewable energy sources，"he says．

　　16．Solar-power satellites will use radio waves to beam energy down from space．

　　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．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　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

　　職稱英語考試?yán)砉ゎ怉級閱讀判斷題 2

　　The earth has an outer shell of rigid pieces called tectonic plates (地殼構(gòu)造板塊). The plates include both ocean floor and dry land. Some have whole continents on top of them. The continents on top of the plates are just going along for a slow ride, moving only about four inches per year. But even this small movement causes three types of big interactions.

　　One type is ocean ridges. These ridges develop in places where two plates are moving away from each other. As the plates separate, hot magma (巖漿) flows up to fill the space. New crust (地殼) builds up on the plate boundaries and causes ocean ridges. These ridges form long mountain ranges, which only rise above the ocean surface in a few places.

　　Another type of reaction-trenches-occurs between two plates that are moving toward each other. As the plates meet, one bends downward and plunges undemeath the other. This forms deep ocean trenches. The Marianas Trench off Guam in the western Pacific Ocean has a depth of more than 36,000 feet. This is the lowest point on the ocean floor. If the leading edges of the two colliding plates carry continents, then the layers of rock in the overriding plate crumple (變皺) and fold. A plate that carried what is now lndia collided with the southern edge of the plate that carried Europe and most of Asia. This caused the Himalayas, the world’s highest mountains.

　　The third reaction is transform faults (轉(zhuǎn)換斷層). These faults occur where two plates that are traveling in opposite directions slide past each other. Severe earthquakes can occur. The San Andreas Fault in Califomia is a good example of this type of movement.
