So trade­offs will have to be made. Some scenic sports 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 trade­offs 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 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

　　trade­offs and the institution 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.

　　本文是一篇说明文。19世纪，美国政府拨款修建铁路和公路，这既带来了好处，也带来了一些不利。现在21世纪，一种新型的电力系统会给美国带来好处还是坏处，这是值得考虑的一个问题。在建这种新型的电力系统时，我们要记住铁路和公路的影响。

　　1．What was the problem caused by the construction of the railways?

　　A. Small towns along the railways became abandoned.
