快乐小博士巩固与提高系列答案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 21st 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 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 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.

Obama Still Smokes in Secret
US President Barack Obama has just made life more difficult for cigarette makers．He has just signed a law that will set tough new rules for the tobacco industry．The new law gives the US Food and Drug Administration the power to strictly limit the making and marketing of tobacco products．
At a White House signing ceremony Monday, Obama said that he was among the nearly 90% of smokers who took up the habit before their 18 th birthday．
Obama, who has publicly struggled to give up smoking, said he still hadn’t completely kicked the habit．Every now and then he still smokes in secret．
“As a former smoker I struggle with it all the time．Do I still smoke sometimes? Yes．Am I a daily smoker, a constant smoker? No．” Obama said at a news conference．
“I don' t do it in front of my lads．I don 't do it in front of my family．I would say that I am 95% cured, but there are times when I mess up, " he said．
"Once you go down this path, it' s something you continually struggle with, which is exactly why the law is so important．The new law is not about me, it' s about the next generation of kids coming up．What we don ' t want is kids going down that path," he said．
Nearly 20% of Americans smoke and tobacco use kills about 440,000 people a year in the United States due to cancer, heart disease, and other serious diseases．
