It is shocking to notice that extreme violence has occurred with frequency on campus in recent years, home and abroad.
In November this year, a college student from a prestigious university stabbed to death a professor who was preparing for his teaching. In the US a deadly shooting by a Korean American college student resulted in 33 classmates’ death. These tragedies seem to be unimaginable when college students are regarded as the elite of the society. Some people claim that the higher education do not improve moralities of those college students. Others believe that college students are fragile in their internal minds. These opinions do make sense when we take the overloaded pressure imposed on college students into consideration. While there is no way to rid totally the world of such violence, it is more important to take measures to avoid those occurrences.
Among those solutions, psychological aid is one. If psychological consulting had been resorted to, those tragedies should have happened with less possibility.

正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。
但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。
