二 現代文語段閱讀
(一)(12分)
不必說碧綠的的菜畦,光滑的的石井欄,高大的的皂莢樹,紫紅的的桑葚;也不必說鳴蟬在樹葉里長吟,肥胖的黃蜂伏在菜花上,輕捷的叫天子(云雀)忽然從草間直竄向云霄里去了。單是周圍的短短的泥墻根一帶,就有無限趣味。油蛉在這里低唱,蟋蟀們在這里彈琴。翻開斷磚來,有時會遇見蜈蚣;還有斑蝥,倘若用手指按住它的脊梁,便會啪的一聲,從后竅噴出一陣煙霧。何首烏藤和木蓮藤纏絡著,木蓮有蓮房一般的果實,何首烏有臃腫的根。有人說,何首烏根是有像人形的,吃了便可以成仙,我于是常常拔它起來,牽連不斷地拔起來,也曾因此弄壞了泥墻,卻從來沒有見過有一塊根像人樣。如果不怕刺,還可以摘到覆盆子,像小珊瑚珠攢成的小球,又酸又甜,色味都比桑葚要好得遠。

(二) 高鄰(小小說)(12分)
鄭益民
(1) 那是十多年前的事了。
(2)當時,我們所在的江南小城沒有高層和小高層。經過千番比較萬番排除之后,我們拖著疲憊的身軀,滿心歡喜地搬進了運河邊一幢六層樓房的第五層——白天能縱情鳥瞰千年運河,夜晚能枕著運河悠悠的風聲和水聲而眠,該多么愜意啊。
(3)遠親不如近鄰。初來乍到,免不了要去拜訪列位高鄰。六樓住的是一對新婚不久的高校教師,男的文質彬彬,女的溫文爾雅,家中窗明幾凈,地板一塵不染。能有這樣的高鄰,我們暗暗喜在心里。
(4)然而,我們的喜悅很快便被一個爛桔子擊碎了。
(5)一個美麗的黃昏,微風習習,汩汩的運河水將紅艷艷的夕陽揉碎在波紋間,幻化出一片夢一般絢麗的景觀。我憑欄而立,正自心醉神迷,忽聽“砰”的一聲,一個球狀的橙色物體重重地擊打在晾衣架上,酸臭的味兒炸裂開來,逼得我直往后退。
(6)在好奇心的驅使下,我悄悄探出腦袋,發現女主人姿態婀娜地倚在陽臺上,翹著蘭花指兒,正優雅地嗑著瓜子,瓜子殼兒天女散花般向下飄飛。我的心也緊跟著直往下墜。
(7)休完年假回家,打開陽臺的窗子,我不覺愣住了:一條八成新的薄棉絮斜斜地掛在晾衣架上。這肯定是樓上高鄰的!我二話不說,拎起棉絮徑直敲開了實在不想敲開的門。好一會兒,門被打開了一道縫縫,縫縫里探出了男主人的腦袋:“哦,這棉絮是我們扔掉的。你直接扔掉好了,不用拿上來的。”我當時的感受,用現在的話來說,就一字:暈。
(8) 有了這樣的高鄰,入住才一年,我們便開始考慮換房了。
(9)周日清晨,妻子正準備晾衣服,突然驚叫起來。我跑過去一看,只見一個比初升的太陽更耀眼的紅色的塑料袋,裝了大半袋的桔子皮和香蕉皮,高掛在晾衣架上,正耀武揚威地在我們面前晃悠。盛怒之下,我抱定得罪高鄰的決心,不顧妻子的勸阻,奮筆疾書:
招領啟事
今日,本人在自家晾衣架上撿到垃圾一袋,請失主自覺領回。
此致敬禮!
501室
某年某月某日
(10)書寫完畢,我立即將招領啟事貼到一樓樓梯口,并找來榔頭和釘子,將裝滿垃圾的袋子掛在招領啟事旁邊。
(11)傍晚,垃圾不見了,招領啟事也被撕掉了。
(12) 從那以后,我們再也沒有動過搬家的念頭。
12 試分析第(5)段中“一個美麗的黃昏,微風習習,汩汩的運河水將紅艷艷的夕陽揉碎在波紋間,幻化出一片夢一般絢麗的景觀”在文中的作用。(3分)
13 第(6)段“我的心也緊跟著直往下墜”一句中的“墜”能否換成“落”,為什么?(3分)
14 在第(7)段中,作者寫道:“我當時的感受,用現在的話來說,就一字:暈”請揣摩“我”此時的心理,寫一段不少于30字的心理描寫。(3分)
15 根據全文內容,說說標題“高鄰”的作用。(3分)
三 文言文閱讀(13分)
