As the railroads and the highways shaped the American West in the past centuries, a new electrical generating(發(fā)電)and transmission (輸送) 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(政府撥地) 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(物種) 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.
【小題1】What was the problem caused by the construction of the railways?

A.Small towns along the railways became abandoned.
B.Land in the West was hard to manage.
C.Some railroad stops remained underused.
D.Land grants went into private hands.
【小題2】What is the major concern in the development of alternative energy according to the last two paragraphs?
A.The use of money and power.
B.The transmission of power.
C.The conservation of solar energy.
D.The selection of an ideal place.
【小題3】What is the author’s attitude towards building solar plants?
A.Disapproving.B.Approving.C.Doubtful.D.Cautious.
【小題4】Which is the best title for the passage?
A.How the Railways Have Affected the West
B.How the Effects of Power Plants Can Be Reduced
C.How Solar Energy Could Reshape the West
D.How the Problems of the Highways Have Been Settled

I’ll call my father tomorrow which is Father’s Day. Every other  1  I call,Morn answers and Dad quietly picks up the  2  and listens in to our conversation.But  3  Father’s Day, we will talk a little about my job,my family and the weather. Then Dad will say,“Thanks for 4    ,son ,”and hang up.

       5  it is almost summer, every year after our Father’s Day talk,I’m left with images of my father and the cold.As a boy I watched him out of the kitchen window  6  our lane(道) of snow with the first snow blower(旋轉(zhuǎn)式清雪機(jī)). First,he’d do our walk and then he’d blow the lanes of the shut-ins(不能出門的病人),the single morns,and poorer folks,  7  could not seem to get it together.

    I  8  him and learned from him,but I  9  not remember my father and me ever having much of a conversation.Nothing that he  10  shared、vim me in a heart-felt way showed that he may be  11 ,upset or ready to climb the wall.

 The last time I saw my father, I asked him to go out for a  12  with me.The sun was setting over the lake and I said,“Come on.We don’t  13   much time together any more. Let’s go. ”Father looked at me meaningfully and said,“  14  . ”

 That visit to my father was about a week before September 11 th.I was near Ground Zero on that day and for five hours  15  the first plane struck, my family did not know of my whereabouts(下落). 16   for me I arrived back at our home in Brooklyn.My biggest  17    was that my wife told me my father was  18  to drive from his home on Lake Huron to Ground Zero to find me.

    To love the remote father is to face this paradox(矛盾):to accept his refusal of my  19 for a sunset walk with his worry that I might have died with thousands of others last September; to deeply know, if not accept,that is his way, the way a man of  10  words,snowblower of shut-ins and lonely hearts,can best show a father’s love.
