一天，陆军部长斯坦顿来到林肯那里，气呼呼地对他说一位少将用侮辱的话指责他偏袒一些人。林肯建议斯坦顿写一封内容尖刻的信回敬那家伙。
“可以狠狠地骂他一顿。”林肯说。
斯坦顿立刻写了一封措辞强烈的信，然后拿给总统看。 “对了，对了。”林肯高声叫好，“要的就是这个！好好训他一顿，真写绝了，斯坦顿。” 但是当斯坦顿把信叠好装进信封里时，林肯却叫住他，问道：“你干什么？” “寄出去呀。”斯坦顿有些摸不着头脑了。 “不要胡闹。”林肯大声说，“这封信不能发，快把它扔到炉子里去。凡是生气时写的信，我都是这么处理的。这封信写得好，写的时候你已经解了气，现在感觉好多了吧，那么就请你把它烧掉，再写第二封信吧。”
December 25 is Christmas Day(圣诞节). Christmas is an important holiday in many countries. On Christmas Day, most families get together for a big dinner. They give presents to each other and visit friends. The Christmas tree is an important part of the Christmas holiday. Most families buy trees. The families decorate(装饰) the tree together. Parents usually tell their children that Father Christmas comes during the night and brings presents to good children. Of course, Father Christmas isn't real. The parents of the children are really "Father Christmas". They put the presents under the tree or into their children's stocking(长统袜) after the children go to sleep.
