看看解释：The text is perfectly aligned on both the left and right sides of the screen and there is no ragged This is what is called fully justified text and it is as easy to achieve as right or centre justified text 上面这段英文，就不是“fully justified”，因为第一行右端出现了空白，与第二行的字母没有对齐。在Word的里排版，默认总是“fully justified”，因为一旦出现某个单词在一行之内放不下，那么这个单词会放在下一行，而上一行的其它单词之间的间距会自动增大，以填充出现的空白。简单地说，“fully justified”，就是Word里的“两端对齐”
