问答题

阅读下面的语段,完成后面的问题。每当看到现在的孩子背着那印满各式各样卡通画的精致书包上学时,我就会想起属于我的第一个书包。那是个花格子书包,妈妈做的。7岁那年,我终于拥有了上学的资格。可是我没有书包。那时,我们乡下孩子最常背的就是用花布拼成的花格子书包。每当同学们谈论谁的书包哪块花布多么多么好看时,我都会躲得远远的,心里却一遍遍地喊着:我也要有一个花格子书包!我终于向母亲开了口。"家里没有碎花布。"妈妈平静地说。"我要!"我固执地坚持着,却不敢看妈妈的脸。家里的窘境我是知道的。面对我的倔强,妈妈没有再说话。从那以后,我发现从来不喜欢串门的妈妈开始串门了。对于寡言少语的她来说,和人谈天说地是多么吃力的事情!有好几次,在一边玩耍的我发现妈妈的脸被别人的话锋逼得通红通红。不知串了多少家的门,不知有多少次艰难的开口,妈妈终于攒够了做书包的花布。开学的前夜,妈妈把书包做好了。美丽的图案,细密的针脚--这真是一个可爱的书包!我还惊喜地发现,书包里面居然还有一个夹层。这可是我们村独一无二的新设计啊!我兴奋地把书包看了又看,然后抬头看看妈妈的脸,她的眼神十分安适。"好好学习。"她依然平静地说。躺在床上,我的泪水忍不住淌了一脸,愧疚和不安开始一点一点地吞咽我的喜悦和满足。我知道这书包意味着什么:这块块鲜艳的花方格是她一缕缕被撕裂的矜持和尊严,这道道匀净的线路是她那颗绵延万里却从不言爱的心啊!第二天上学时,我郑重地背上了这个书包。书包里装的东西很少,但我却觉得它沉甸甸的。后来,它一直陪伴我读完了小学和中学,直到它不能再用,我也依然保存着它。因为我知道:这个书包必定是世界上最珍贵、最美的书包。

谈谈你对文中最后段落中"书包里装的东西很少,但我却觉得它沉甸甸的"一句的理解。(3分)
