爱能表达的方式有很多种：一个吻、一个拥抱、一个暖暖的热水袋、一杯热气腾腾的牛奶……而我所得到的爱，确切的说，应该是母爱，却是两道深深的牙齿印。它不是一般的“深”，而是直穿心胸的那种刻骨铭心的“深”。
现在会想起我胳膊上哪两道牙齿印的痕迹，我真的从中感触到了许多许多……
第一道牙齿印：那天，我拿着87分的考卷垂头丧气地在回家的路上走着走着，脚上像灌了铅似的，怎么也走不快，眼泪一直在眼睛里打。此时的心，那是七上八下、忐忑不安，又如在进行一场混战，脑子里胡思乱想……不知不觉，到家了，我鼓励自己说：面对现实吧，该发生的总是要发生的`。于是，我便踏进了家门。妈妈早已在家里恭候多时，“怎么样，考了几分妈妈一听这个数字后，顿时脸色发白，但她并没有发火，而是用她那乌黑的眼珠盯着我，我连抬头看一下都不敢，感觉四面八方都有一支枪在瞄准着我。“你过来。”妈妈开口说话了，语气要比平时严肃的多。我走了过去，全身瑟瑟发抖，不知妈妈会用什么样的方式来惩罚我。可让我意想不到的是，妈妈竟然抓起我的胳膊在上面咬了一口，我咬咬嘴唇忍了下去。之后妈妈对我说：“我也不想怎么惩罚你，只想用这个牙齿印来告诫你：不要灰心，不要气馁，下次一定要考好，否则牙齿印还会在你的胳膊上出现一个！”我微微地点了点头。
第二道牙齿印：几天后，在一次数学测验中我得了100分，心里甭提多高兴了，真想对全世界大喊一声，来释放我所有心中的快乐。放学后，我第一个冲出教室，带着满怀的激情直奔回家，对妈妈喊道：“妈妈，我考100分啦！”我看见了，妈妈的脸上也洋溢着笑容，可让我等来的又是一个牙齿印，霎那间，我愣住了。我不明白，这到底是为什么？“就算你考了100分也不能骄傲，虚心使人进步，骄傲使人落后。”妈妈语重心长的说。我的眼睛湿润了，眼泪不停地涌出来，眼睛的“大坝”已挡不住洪水的来袭。我扑到妈妈的怀里，放声大哭着。
妈妈就是用这种方法使我在人生的起跑线上更进一步，而那两道深深的牙齿印，不但刻得深，爱得也深。它比任何人所付出的都要深，一直深到你心的边际。这种爱，远远超出了无底洞，为我铺出一条前进的路！
