　　在商业和正式文件写作中，越来越多的用到圆点散句。除了更易读之外，它们更能从视觉上引起人们注意。作者需要决定在圆点之后用什么形式来写，是用名词，动词，形容词，副词，还是介词短语，定语从句甚至完整的句子。应该记住的是它们相互间应该保持一致。平行结构较多用。

　　精典范例：

　　Let the word go forth from this time and place, to friend and foe1 alike, that the torch has been passed to a new generation of Americans, born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage, and unwilling to witness or permit the slow undoing of those human rights to which this nation has always been committed, and to which we are committed today at home and around the world.

　　So let us begin anew, remembering on both sides that civility is not a sign of weakness, and that sincerity is always subject to proof. Let us never negotiate out of fear, but let us never fear to negotiate.

　　Now the trumpet summons us again - not as a call to bear arms, though arms we need2; not as a call to battle, though embattled we are3; but a call to bear the burden of a long twilight struggle, a year in and year out "rejoicing in hope, patient in tribulation," a struggle4 against the common enemies of man: 5 tyranny, poverty, disease, and war itself.

　　And so, my fellow Americans, ask not what your country can do for you6; ask what you can do for your country.
