A篇

Teenager bedwetting can be caused by a number of factors, some of which may be related to serious health issues. Bedwetting that starts suddenly can be a sign of serious trauma（创伤）or minor problems, like allergies. An isolated incident may be related to substance abuse.

One of the major causes of teenager bedwetting is simple genetics. Some teenagers mature more slowly than others, some have underdeveloped bladders（膀胱）, and some have a family history of bedwetting. Given that these problems are usually present throughout childhood, it is likely that teenage bedwetting due to these causes will have a long history. Most people do eventually grow out of this type of bedwetting.

In some cases, teenage bedwetting can be caused by dietary changes. Increases in caffeine, dairy products, and other substances can cause a teenager to relapse （复发）into bedwetting. Isolating the problem can be difficult because the teenager may or may not be allergic to the substance.

Emotional troubles sometimes lead to bedwetting as well. Stress and trauma, in particular, can lead to uncontrolled bedwetting. In some cases, a teenager may be hiding the source of the severe trauma and may not be willing to give information when confronted. Cases like these are often handled by psychologist.

There are a number of causes of teenage bedwetting that relate to how urine （小便）is produced and the available space in which to store it. A teenager may for any number of reasons begin to produce excess urine. It is also possible that he or she has a small bladder that is not capable of handling the amount of urine produced at night. Having a small bladder does not necessarily imply that a person will wet the bed, so bladder size may not always provide a definitive answer. In combination with a sleep disorder, which may prevent the teenager from waking up when the bladder is full, these conditions can produce bedwetting.

It can be hard to diagnose（诊断）the cause of bedwetting in teens, but understanding why a teenager is wetting the bed can be helpful not only for health but for emotional security as well. Teenagers are often ashamed of wetting the bed, and this shame may interfere with their other activities. By diagnosing the cause even if there is no cure, a teenager who suffers from bedwetting may experience an improvement in overall quality of life.

Think what you are!

Carbon and oxygen taken together, one atom each, gives you the deadly gas carbon monoxide (CO) . On the other hand, these very two elements（成分）on some other proportion（比例）provide us with carbon dioxide（CO2）, the harmless gas. When these basic elements can behave in this way so can the human mind!
