阅读《背影》选段,完成下列小题。

    ①我与父亲不相见已二年余了,我最不能忘记的是他的背影。那年冬天,祖母死了,父亲的差使也交卸了,正是祸不单行的日子,我从北京到徐州,打算跟着父亲奔丧回家。到徐州见着父亲,看见满院狼藉的东西,又想起祖母,不禁簌簌地流下眼泪。父亲说,“事已如此,不必难过,好在天无绝人之路!”

    ……

    ②我看见他戴着黑布小帽,穿着黑布大马褂,深青布棉袍,蹒跚地走到铁道边,慢慢探身下去,尚不大难。可是他穿过铁道,要爬上那边月台,就不容易了。他用两手攀着上面,两脚再向上缩;他肥胖的身子向左微倾,显出努力的样子。这时我看见他的背影,我的泪很快地流下来了。我赶紧拭干了泪,怕他看见,也怕别人看见。我再向外看时,他已抱了朱红的橘子望回走了。过铁道时,他先将橘子散放在地上,自己慢慢爬下,再抱起橘子走。到这边时,我赶紧去搀他。他和我走到车上,将橘子一股脑儿放在我的皮大衣上。于是扑扑衣上的泥土,心里很轻松似的,过一会说,“我走了;到那边来信!”我望着他走出去。他走了几步,回过头看见我,说,“进去吧,里边没人。”等他的背影混入来来往往的人里,再找不着了,我便进来坐下,我的眼泪又来了。

    ③近几年来,父亲和我都是东奔西走,家中光景是一日不如一日。他少年出外谋生,独力支持,做了许多大事。那知老境却如此颓唐!他触目伤怀,自然情不能自已。情郁于中,自然要发之于外;家庭琐屑便往往触他之怒。他待我渐渐不同往日。但最近两年的不见,他终于忘却我的不好,只是惦记着我,惦记着我的儿子。我北来后,他写了一信给我,信中说道,“我身体平安,惟膀子疼痛利害,举箸提笔,诸多不便,大约大去之期不远矣。”我读到此处,在晶莹的泪光中,又看见那肥胖的,青布棉袍,黑布马褂的背影。唉!我不知何时再能与他相见!
