              为中华之崛(jué)起而读书
     12岁那年,周恩来离开家乡,来到了东北。当时的东北,是帝国主义列强在华争夺的焦点。他在沈阳下了车,前来接他的伯父指着一片繁华热闹的地方,对他说:“没事可不要到那个地方去玩啊!”
   “为什么?”周恩来不解地问。
   “那是外国的租界地,惹出麻烦来可就糟了,没处说理去!”
   “那又是为什么呢?”周恩来打破砂锅问到底。
   “为什么?中华不振啊!”伯父叹了口气,没有再说什么。
不久,周恩来进了东关模范学校读书。他始终忘不了大伯接他时说的话,经常想:“租界地是什么样的?为什么中国人不能去那,而外国人却可以住在那里?这不是中国的土地吗?……”一连串的问题使周恩来迷惑不解,好奇心驱使着他,一定要去看个究竟。
一个风和日丽的星期天,周恩来背着大伯,约了一个要好的同学闯进了租界地。嘿!这一带果真和别处大不相同:一条条街道灯红酒绿,热闹非凡。街道两旁行走的大多是黄头发的、白皮肤、大鼻子的外国人和耀武扬威的巡警。
      正当周恩来和同学左顾右盼时,忽然发现巡警局门前围着一群人,正大声吵嚷着什么。他们急忙奔了过去,只见人群中有个衣衫褴褛的妇女正在一旁哭诉着什么,一个大个子洋人则得意洋洋的站在一旁。一问才知道,这个妇女的亲人被洋人的汽车轧死了,她原指望中国的巡警局能替她撑腰,惩处这个洋人。谁知中国巡警不但不惩处肇事的洋人,反而把她训斥了一顿。围观的中国人都紧握着拳头。但是,在外国的租界地里,谁又敢怎么样呢?只能劝劝那个不幸的妇女。这时,周恩来才真正体会到伯父说的“中华不振”的含义。
      从租界地回来后,同学们常常看到周恩来一个人在沉思,谁也不知道他究竟在想什么。直到在一次修身课上,听了周恩来的发言才解开了这个谜。
那天修身课上,魏校长向同学们提出了一个问题:“请问诸生为什么读书?”
      同学们踊跃回答,有的说:“为做官而读书”,也有的说:“为挣钱而读书”,“为明理而读书”……周恩来一直静静的坐在那里,没有抢着发言。魏校长注意到了,打手势让大家静下来,点名让他回答。周恩来站了起来,清晰而坚定地回答:“为中华之崛起而读书!”
       魏校长听了为之一振!他怎么也没想到,一个十二三岁的孩子,竟有如此的抱负和胸怀!他睁大眼睛又追问了一句;“你再说一遍,为什么而读书?”
    “为中华之崛起而读书!”
       周恩来铿锵有力的话语,博得了魏校长的喝彩;“好啊!为中华之崛起!有志者当效周生啊!”
       是的,少年周恩来在那时就已经认识到,中国人要想不受到帝国主义的欺凌,就要振兴中华。读书,就要以此为目标。
