    3、重要語(yǔ)句的理解“可是一個(gè)人并不是生來(lái)要給打敗的,你盡可把它消滅掉,可就是打不敗他。”解析:這是老人第一次回合之后的內(nèi)心獨(dú)白,也是此小說(shuō)的核心精神,充分體現(xiàn)了老人桑地亞哥的生命理念。整句話可以分為兩部分來(lái)理解,前句告訴我們,人生活在自然與社會(huì)當(dāng)中,必不可少要面臨一些坎坷、磨難,這些磨難、坎坷完全可以造成軀體的消滅、消亡,這是人生命的脆弱性。后句,面對(duì)挫折,只要保持一種樂(lè)觀的精神,擁有一顆堅(jiān)強(qiáng)的心靈,那么,人類執(zhí)著奮斗的精神將永不磨滅。4、象征主義題目是《老人與?!?,而表明上,小說(shuō)是寫(xiě)一位老人及其在海上的經(jīng)歷,但實(shí)際上,老人的形象極具概括性,他已經(jīng)超越了一個(gè)人的存在,而成為了人生的一種象征。老人桑地亞哥就是“硬漢子”的代表,大海則是生命旅途的象征,鯊魚(yú)則是我們行走中的“強(qiáng)物”,厄運(yùn)的象征。人的一生不可能一帆風(fēng)順,不經(jīng)歷風(fēng)雨,怎能見(jiàn)彩虹,走在人生路途中,不可避免我們都要遇到挫折,被厄運(yùn)所阻撓,只有經(jīng)歷與“鯊魚(yú)”的較量,才能成為強(qiáng)者,唱出最美的歌。

    (二)分析課文,理清思路第1、2段為第一部分,主要是敘事、寫(xiě)景,先敘述集會(huì)的時(shí)間、地點(diǎn),然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽(tīng)之娛”,可以自由地觀察、思考,滿足人們目視耳聞的需求。這里正是與會(huì)“暢敘幽情”、盡興盡歡的絕好處所。這些描寫(xiě)都富有詩(shī)情畫(huà)意,作者的情感是輕松愉快的。第3、4段為第二部分,主要是抒情、議論,作者由美景妙時(shí)引發(fā)出樂(lè)與憂、生與死的感慨。他認(rèn)為人生的快樂(lè)是有極限的,待快樂(lè)得到滿足時(shí),就會(huì)感覺(jué)興味索然。往事轉(zhuǎn)眼間便成為歷史,人到了生命的盡頭就會(huì)死亡。作者由“一死生為虛誕,齊彭殤為妄作”的認(rèn)識(shí),產(chǎn)生了一種珍惜時(shí)間、眷戀生活、熱愛(ài)文明的思考。雖然文中的壽夭、生死不能自由決定,從而有些傷感,但作者仍然認(rèn)識(shí)到盛衰、生死是必然的。人生無(wú)常,時(shí)不我待,故著文留傳后世,以承襲前人,啟示來(lái)者。
