阅读下面的文章,完成下列小题。

    好大圣,拨回筋斗,那消一个时辰,早至南洋大海,住下祥光,直至落伽山上,撞入紫竹林中,忽见木叉行者迎面作礼道:“大圣何往?”行者道:“要见菩萨。”木叉即引行者至潮音洞口,又见善财童子作礼道:“大圣何来?”行者道:“有事要告菩萨。”善财听见一个告字,笑道:“好刁嘴猴儿!还象当时我拿住唐僧被你欺哩!我菩萨是个大慈大悲,大愿大乘,救苦救难,无边无量的圣善菩萨,有甚不是处,你要告他?”行者满怀闷气,一闻此言,心中怒发,咄的一声,把善财童子喝了个倒退,道:“这个背义忘恩的小畜生,着实愚鲁!你那时节作怪成精,我请菩萨收了你,皈正迦持,如今得这等极乐长生,自在逍遥,与天同寿,还不拜谢老孙,转倒这般侮慢!我是有事来告求菩萨,却怎么说我刁嘴要告菩萨?”善财陪笑道:“还是个急猴子,我与你作笑耍子,你怎么就变脸了?”

    正讲处,只见白鹦哥飞来飞去,知是菩萨呼唤,木叉与善财遂向前引导,至宝莲台下。行者望见菩萨,倒身下拜,止不住泪如泉涌,放声大哭。菩萨教木叉与善财扶起道:“悟空,有甚伤感之事,明明说来,莫哭,莫哭,我与你救苦消灾也。”行者垂泪再拜道:“当年弟子为人,曾受那个气来?自蒙菩萨解脱天灾,秉教沙门,保护唐僧往西天拜佛求经,我弟子舍身拚命,救解他的魔障,就如老虎口里夺脆骨,蛟龙背上揭生鳞。只指望归真正果,洗业除邪,怎知那长老背义忘恩,直迷了一片善缘,更不察皂白之苦!”菩萨道:“且说那皂白原因来我听。”
