As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(发电)and transmission (输送) system for the 21^st 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 surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.

The 19 ^th 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 of 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 them. 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 spots 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 21^st century development of the American West as an ideal place for alternative energy is going to throw off a lot of power and money in the region. There are chances for that 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 railroads and the highways.

The money set aside in negotiated trade-offs and the institutions that control it will shape the West far beyond the immediate footprint of power plants and transmission lines. So let’s remember the effects of the railroads and the highways as we construct these new power plants in the West.

阅读下面短文，掌握其大意，然后从1－15各题所给的A、B、C和D项中，选出最佳选项。

There are stories about two U．S . presidents，Andrew Jackson and Martin Van Buren，which attempt to explain the American English term OK．We don’t know if either story is true，but they are both interesting．

The first explanation is based on the fact that President Jackson had very little education．In fact，he had difficulty reading and writing．When important papers came to Jackson，he tried to read them and then had his assistants explain what they said．If he approved of a paper, he would write “all correct”on it．The problem was that he didn’t know how to spell．So what he really wrote was “ol korekt”．After a while，he shortened that term to “OK”．

The second explanation is based on the place where President Van Buren was born，Kinderhook，New York．Van Buren’s friends organized a club to help him become President .They called the club the Old Kinderhook Club，and anyone who supported Van Buren was called“OK”．
