I walked along the sidewalk that borders the west side of Central Park this morning，wondering at its shape：Hexagonal（六邊形的） paving stones underneath my feet were bordered by brickwork，with a tidy stone wall running alongside.Just past the wall lay the park itself，where delicate branches of leafless trees reached to the blue sky，and sparrows emerged from trees.
   The contrast between the straight-lined，orderly，man-made sidewalk and the complex diversity of nature just beyond its border made me think about the differences between natural creation and man's creation.
   The world holds many examples of circles：the moon，grapes，drops of water and the center of flowers.Triangles（三角形） are readily evident，too.There are kitty cat noses and ears，mountain peaks and river deltas.
   But what about the most common shape in the man-made world，the rectangle（矩形）？I searched my brain for natural equals.Though I thought and thought，I came up with only two：teeth and salt crystals.That surprised me.Do we prefer rectangles simply because it's easier to plan and build with blocks and straight lines？Or does it have something to do with the idea that humans tend to assume life is supposed to be linear？I don't know.
   There are bent lines everywhere.As I look at the beauty of，a tree in winter，with its branches reaching skyward in a seemingly untidy but obviously planned pattern，I can apprehend something of what that means.
   Our world isn't always tidy and predictable in the way that I want it to be.There are twists and turns in my life that I can't foresee or predict.That doesn't mean branching off in unexpected directions is bad or wrong.It means that when I find myself in each new place，I need to continue growing and reaching upward.
