五、阅读理解。
Do you have true friends? Do you want to know better between you and your friends? There are three different kinds of friends：“pest friends”，“guest friends”，and “best friends”.
The first kind of friend is simply acquaintances (熟人)，and all you usually know about them is their names. You may meet this kind of friend at school，at work，or on the bus，but you don't miss them when they're not around. When this kind of friend does something bad，you don't tell them. They are not called “pest friends”.
The second kind of friend could also be called “social partners”. They are closer than acquaintances，but not as close as true friends. You know their names，a little of what they like or dislike，and a little of their family histories；you usually have a few things in common，but you don't talk about anything deep (深的)，such as your wishes or fears (害怕)，and they don't open up to you how they really feel.
The last kind of friend，the “best friend”，is the one you know the deepest. You're like family，and know everything about each other. You have no problem staying at each other's houses，and you share your deepest feelings and thoughts. They will correct you when you're wrong，and though they may not be perfect (完美的)，they at least will always care about you，and never do anything on purpose (故意) to hurt you.
We all have our pest，guest，and best friends. We should value (重视) all friendships and remember，all best friends start out as just acquaintances.
