     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.
