阅读《蒲公英》,完成后面小题。
                                                                                                      蒲公英
        那是春日的一个上午,阳光明媚,清风徐来。草绿了,花开了,那些花儿,在远远近近的绿草间里像星一样闪烁。无数老人和孩子在草里流连花里漫步,也像春天的阳光一样灿烂
        那时侯我正失意着,骑着车子在堤上乱走。一不留神,车子歪了下去,险些撞着坐在堤下的一个老人。在向老人表示了歉意之后,我没走,就坐在老人身边。
        那段日子,失意就像春天的草一样在我的思想里蓬蓬勃勃。很久以来,我看见一片落叶,便伤感,觉得自己也是一片落叶。我看见一片落花,也伤感,觉得自己是一片落花。看见流水,还是伤感,觉得自己的生命就在这平平淡淡中像水一样流逝了。
        老人看出了我的失意,跟我说起话来。老人说:“年轻人,怎么这样无精打采呢?”
        我手里缠着一根草,在老人问过后,我晃了晃那根草说:“我这辈子将像这根草一样平凡。”
        老人没做声,只是看着我。
        在老人的注视下我说了起来,我说我是一个很不幸的人,初中是因一场病休学了一年。此后,学习成绩一直很差,勉强读了高中后,又没考取大学。我又说一个人连大学都没有上过,毫无疑问是一个平凡的人,我这一辈子将在平凡中度过。我还说我是一个不甘平凡的人,我从小就立下志愿,一定要让自己的人生辉煌。
        说到这里我流泪了,我心里装不下太多的失意,它像汹涌的洪水,找到了决口。
        老人这时开口了,老人说:“你知道你手里是什么草吗?”
         “不知道。”
         “它是蒲公英。”
        “这就是蒲公英吗,我常在诗人的笔下见到它,可它也很普通呀。”我说。
        “你没看见它开着花吗?”
         “看见了,一种小花,毫不起眼。”
         “是不起眼,但它也可以辉煌。”
         “在诗人的笔下?”
         “不。”老人摇了摇头,注视着我。俄顷,他站了起来,跟我说:“我带你去看一个地方吧。”
         我听从了老人,也站了起来。
        随后,我跟着老人沿着那条堤往远处走,大约二十分钟后,我看见了一个足以让我这一生都震撼的景致。那是一块很大的河滩,有几十亩甚至上百亩大。整个河滩上全部是蒲公英,漫无边际。蒲公英开花了,那些毫不起眼的黄黄白白的小花,在阳光下泛着粼粼波光。那样美,那样灿烂,那样妖娆,那样蔚为壮观,炫目辉煌。
        一朵小花,也可以这么辉煌么?
        我们再没说话,就那样伫立着,起风了,花儿轻轻地向我涌来。我忽然觉醒了,心里一下子飘满了那些美丽的蒲公英。
         我觉得自己也是一朵蒲公英了!
         一直到现在,那漫无边际的蒲公英还在我眼里烂漫着,而且,在那里我看见了自己。
