题型:单项选择题

“金窝银窝,不如家里的草窝”。但人是不安分的动物,多少人仗着年少气盛,横一横心,咬一咬牙,扬一扬手,向恋恋不舍的家乡告别,万里投荒,去寻找理想,追求荣誉,开创事业,富有浪漫气息。有的只是一首朦胧诗——为了闯世界。多数却完全是沉重的现实主义格调:许多稚弱的童男童女,为了维持最低限度的生存要求,被父母含着眼泪打发出门,去串演各种悲剧。人一离开乡土,就成了失根的兰花。逐浪的浮萍,飞舞的秋蓬,因风四散的蒲公英。 对文中画线句子理解正确的是( )。

A.写出了远离乡土的游子们孤苦无助的境遇

B.是对年少气盛的人去寻找理想、开创事业的描述

C.乡土情结存在于每一个人心中

D.在外面闯世界的人都不想回家
