电子狂客搜集整理于2011-05-14 《简爱》是一本具有多年历史的文学着作。至今已152年的历史了。它的成功在于它详细的内容，精彩的片段。在译序中，它还详细地介绍了《简爱》

的作者一些背景故事。

从中我了解到了作者夏洛蒂．勃郎特的许多事。她出生在一个年经济困顿、多灾多难的家庭；居住在一个远离尘器的穷乡僻壤；生活在革命势头正健，国家由农

民向工业国过渡，新兴资产阶级日益壮大的时代，这些都给她的小说创作上打上了可见的烙印。

可惜，上帝似乎毫不吝啬的塑造了这个天才们。有似乎急不可耐伸出了毁灭之

手。这些才华横溢的儿女，都无一例外的先于父亲再人生的黄金时间离开了人间。惜乎，勃郎特姐妹！ 为电子而狂热 《简爱》这本小说，主要通过简。爱与罗切斯特之间一波三折的爱情故事，塑

造了一个出生低微、生活道路曲折，却始终坚持维护独立人格、追求个性自由、主张人生平等、不向人生低头的坚强女性。

简。爱生存在一个父母双亡，寄人篱下的环境。从小就承受着与同龄人不一样的待遇：姨妈的嫌弃，表姐的蔑视，表哥的侮辱和毒打。。。。。。然而，她并没

有绝望，她并没有自我摧毁，并没有在侮辱中沉沦。所带来的种种不幸的一切，相

反，换回的却是简。爱的无限信心，却是简。爱的坚强不屈的精神，一种可战胜的内在人格力量。
