阅读理解。
About this time every year, I get very nostalgic(怀旧的). Walking through my neighborhood on a

fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children

playing games on a hill, and throwing leaves around in the street below. I was one of those children,

carefree and happy. I live on a street that is only one block long. I have lived on the same street for

sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with

a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my

street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked

around and saw how different everything has become. Life on my street will never be the same because

neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy

my precious hill and sell the property to contractors.

It is hard for me to accept that many of my wonderful neighbors are growing old and won't be around

much longer. I have fond memories of the couple across the street, who sat together on their porch swing

almost every evening, the widow next door who yelled at my brother and me for being too loud, and the

crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today

are very old neighbors who have seen better days. The man in the black suit says he wants to die, and

another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is

too tired to bother any more, and the couple across the street rarely go out to their front porch these

days. It is difficult to watch these precious people as they near the end of their lives because at once I

thought they would live forever.

The "comings and goings" of the younger generation of my street are now mostly "goings" as friends

and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The

boundary of our world was the gutter at the end of the street. We got pleasure from playing night games

or from a breathtaking ride on a tricycle. Things are different now, as my friends become adults and

move on. Children who rode tricycles now drive cars. The kids who once played with me now have

new interests and values as they go their separate ways. Some have gone away to college like me, a

few got married, two went into the army, and one went to prison. Watching all these people grow up

and go away makes me long for the good old days.

Perhaps the biggest change on my street is the fact that the city is going to turn my precious hill into

several lots for now homes. For sixteen years, the view out of my kitchen window has been a view of

that hill. The hill was a fundamental part of my childhood life; it was the hub of social activity for the

children of my street. We spent hours there building forts, sledding, and playing tag. The view out of

my kitchen window now is very different; it is one of tractors and dump trucks tearing up the hill. When

the hill goes, the neighborhood will not be the same. It is a piece of my childhood. It is a visual reminder

of being a kid. Without the hill,my street will be just another pea in the pod.

There was a time when my street was my world, and I thought my world would never change. But

something happened. People grow up, and people grow old. Places changes, and with the change

comes the heartache of knowing I can never go back to the times I loved. In a year or so, I will be

gone just like many of my neighbors. I will always look back to my years as a child, but the place I

remember will not be the silent street whose peace is interrupted by the sounds of construction. It will

be the happy, noisy, somewhat strange, but wonderful street I knew as a child.
