　　When we walk through the city, we all experience a kind of information overload but we pay attention only to those that are important to us. We don't stop, we keep our faces expressionless and eyes straight ahead, and in doing so, we are not just protecting ourselves but are avoiding overloading other people as well.

　　We make use of stereotypes（刻板的模式）as convenient ways to make quick judgements about situations and people around us. They may not always be accurate, and they can often be dangerously wrong, but they are used regularly.

　　The problem with the stereotypes is that they restrict experience. By using limited clues to provide us with a rapid opinion of other people or places we may choose to limit our communication. We may decide not to go to certain places because we believe they will not offer something we enjoy.

　　In the city, styles of dress are particularly important with regard to self-presentation. Different groups often use clearly identifiable styles of clothes so that they can be easily recognized. It is becoming increasingly common for brand names to be placed on the outside of clothes, and this labeling makes it easy to send out information about fashion and price instantly, and lets others tell at a distance whether an individual has similar tastes and is a suitable person to associate with.

　　In England, where social grouping or class continues to make social distinctions（区分）, clothes, hairstyles, people's pronunciation and the manner of speaking are all clues to our social group. Class distinctions tend to be relatively fixed, although in the city where greater variety is permitted, they are more likely to be secondary determining factors of friendship and association.

　　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.
