阅读下面的材料,根据要求写一篇不少于800字的文章。
一百多年前,一位穷苦的牧羊人带着两个幼小的儿子以替别人放羊为生。
有一天他们赶着羊来到一个山坡上,一群大雁鸣叫着从他们头顶飞过,并很快消失在远方。牧羊人的小儿子问父亲:“大雁要往哪里飞?”牧羊人说:“它们要去一个温暖的地方,在那里安家,度过寒冷的冬天。”大儿子眨着眼睛羡慕地说:“要是我也能像大雁那样飞起来就好了。”小儿子也说:“要是做一只大雁该多好啊!”
牧羊人沉默了一会儿,然后对两个儿子说:“只要你们想,你们也能飞起来。”
两个儿子试了试,都没能飞起来,他们用怀疑的眼神看着父亲,牧羊人说:“让我飞给你们看。”于是他张开双臂,但也没能飞起来。可是,牧羊人肯定地说:“我因为年纪大了才飞不起来,你们还小,只要不断努力,将来就一定能飞起来,去你们想去的地方。”
两个儿子牢牢记住了父亲的话,并一直为此努力着。等他们长大——哥哥36岁,弟弟32岁时,他们果然飞起来了,因为他们发明了飞机。这两个人就是美国的莱特兄弟。

阅读理解。

   I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves, most of my childhood was spent on books I could get hold of. In fact, I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into, take part in and live in.    With this unshakable belief, I, at fourteen, decided to become a writer. Here too, reading became useful. Every writer starts off knowing that he has something to say, but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with, or agrees with so strongly that it reshapes his own world. He cannot write without loving to read, because only through reading other people's writing can one discover what works, what doesn't and, in the end, together with lots of practice, what voice he has.    Now I am in college, and have come to realize how important it is to read fiction (文学作品). As a law student, my reading is in fact limited to subject matter-the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road, all from the comfort of my own armchair, to experience, though secondhand, exciting experiences that I wouldn't necessarily be able to have in my lifetime.
