Wood is wood?
Yes, but it's not that simple. Each tree species (种类) grows in a certain way, and that affects (影响) the way its wood looks and performs. Foresters divide trees into two kinds: hardwood and softwood species.
Hardwood trees such as oaks (橡树) and maples (枫树) have wood with very short fibers. Paper made from these species is weaker than that made from softwoods, but its surface is smoother, and therefore better to write and print on.
Softwood trees such as pines and spruces have wood with long fibers, and paper made from this type of wood is much stronger. This kind of paper is ideal for making products like shipping containers that require great strength. But the surface is rougher, and that's not as good for writing, printing and many other uses.
Happily, we can blend fibers from hardwoods and softwoods into a single paper, getting just the combination of strength, whiteness, writing surface and other characteristics that we want.
And that's just what we do! Most of the paper you see today is made from both hardwoods and softwoods, a special blend for each purpose.
We make newsprint (新闻纸) to be opaque (不透明的)
so you only see the newspaper's comics (连环画), not the stock market report on the other side!
We make grocery bag paper strong, tissue (纸巾) soft, fine writing paper smooth. Even within the same sort, there's quite a range. Among printing papers, for example, compare the thin sheets of a Bible to the thick, tough pages of a kid's picture book.
