如果你在街上随便问一个还未上学的小朋友，会背什么古诗。

隐娘完全想象得出答案：《锄禾》、《咏鹅》、《草》、《登鹳雀楼》。

这四首出镜率绝对最高。

确实，这四首古诗都收入了小学教材，成为儿童启蒙必背的古诗。

今天，隐娘想说的诗，是白居易的《草》。

白居易的《草》，全名《赋得古原草送别》，背后有一个“居长安不易”的故事流传甚广，诗的最后两句被南唐后主李煜化用成千古名句。

隐娘上小学时，这首诗入选小学课本，诗名叫《草》，当时，只有前四句，读来朗朗上口。

很多年以来，隐娘一直以为这首《草》诗就四句。长大后，才知道，这首诗有八句，全名为《赋得古原草送别》：

离离原上草，一岁一枯荣。

野火烧不尽，春风吹又生。

远芳侵古道，晴翠接荒城。

又送王孙去，萋萋满别情。

这首诗是白居易16岁时所作。

诗题中有“赋得”二字，按科考规矩，凡限定的诗题，题目前必须加“赋得”二字，作法与咏物诗相似。

可知这是白居易少年时准备应试的试帖诗习作，也就是说这是白居易模拟考试的作品。

离离原上草，一岁一枯荣。

这是一首送别诗，白居易安排了一个送别的典型环境：大地春回，芳草芊芊满草原。

原野上长满茂盛的青草，每年秋来枯黄，春天又绿色浓浓。

野草是一年生植物，春荣秋枯，岁岁循环不已。两个“一”字复叠，形成咏叹，又先状出一种生生不已的情味。

野火烧不尽，春风吹又生。

这是全诗的经典之句。

野草生命力顽强，野火燎原，瞬息后，大片枯草被烧得精光。

巨大的毁灭，让人生畏，可来年春天，春风一吹，野草顽强复苏，古原草恢复了勃勃生机。

柔弱的小草战胜了强大的烈火，小草积极的精神让人振奋。

远芳侵古道，晴翠接荒城。

在古道旁，小草散发着芬芳；在阳光下，青翠的小草连着荒城。

一个“侵”字，一个“接”字，再现了草顽强的生命力和古原草的生机勃勃。

又送王孙去，萋萋满别情。

最后两句点题，我在这里送友人归去，那萋萋的芳草尽是离别之情。

以草比离别之情，要知道，那连天的碧草，似乎每一片草叶都饱含别情。

可知这离愁别绪有多浓烈。

南唐后主李煜化用了白居易的这一句，写就了“离恨恰如春草，更行更远还生”的名句，读来意味不尽。

关于这首诗，还有一个流传很广的故事。

话说白居易初到长安参加科举考试的时候，拿着诗作去拜访当时的文坛盟主顾况。

顾况看了白居易的名字后，调侃道：年轻人，长安米价很贵，居此不容易哟。

说完之后，就翻看白居易的诗文，第一篇就是这首《赋得古原草送别》：

离离原上草，一岁一枯荣。

野火烧不尽，春风吹又生。

读完这四句，便不住地赞赏，对白居易说道：你写出这样句子，有这样的才华，住在长安，可是太容易了。

从此以后，顾况逢人就夸赞白居易的才华，白居易在长安的声名大噪。

可以说，这首诗已经成为国民诗词，几乎所有人都会背。

隐娘每当低落时，都会北背一背这首诗。

“野火烧不尽，春风吹又生”每每读来，让人感受到草的顽强与坚韧，这种坚韧通过诗句传到我们心中，让低落的心灵充满了力量。

诗词总有这样的魅力，能用简单而有力的语言，给我们以前进的力量。
