七年级语文下学期期末复习文言文质量检测试题解析1

七年级语文下学期期末复习文言文质量检测试题解析1 一、文言文1.文言文阅读【甲】沧州南一寺临河干,山门圮于河,二石兽并沉焉。

阅十余岁,僧募金重修,求二石兽于水中,竟不可得,以为顺流下矣。

棹数小舟,曳铁钯,寻十余里无迹。

一讲学家设帐寺中,闻之笑曰:“尔辈不能究物理。

是非木柿,岂能为暴涨携之去?乃石性坚重,沙性松浮,湮于沙上,渐沉渐深耳。

沿河求之,不亦颠乎?”众服为确论。

一老河兵闻之,又笑曰:“凡河中失石,当求之于上流。

盖石性坚重,沙性松浮,水不能冲石,其反激之力,必于石下迎水处啮沙为坎穴。

渐激渐深,至石之半,石必倒掷坎穴中。

如是再啮,石又再转。

转转不已,遂反溯流逆上矣。

求之下流,固颠;求之地中,不更颠乎?”如其言,果得之于数里外。

然则天下之事,但知其一,不知其二者多矣,可据理臆断欤?【乙】奴子傅显,喜读书,颇知文义。

亦稍知医药,性情迂缓①,望之如偃蹇②老儒。

一日,雅步行市上,逢人辄问:“见魏三兄否?”或指所在复雅步以往比相见喘息良久。

魏问相见何意。

曰:“适在枯水井前,遇见三嫂在树下作针黹③,倦而假寐。

小儿嬉戏井旁,相距三五尺耳,似乎可虑。

男女有别,不便呼三嫂使醒,故走觅兄。

”魏大骇,奔往,则妇已俯井哭子矣。

夫僮仆读书,可示佳事。

然读书以明理,明理以致用也。

食而不化,至昏聩僻谬④,贻害无穷,亦何贵此儒者哉!(选自纪昀《阅微草堂笔记》)【注释】①迂缓:迂腐迟缓。

②惬赛:高耸,引申傲慢。

③针黹(zhǐ):针线活。

④昏聩僻谬:糊里糊涂,怪癖荒谬。

(1)用“/”给乙文中画线处断句(限断三处)。

或指所在复雅步以往比相见喘息良久。

(2)下列甲、乙两文的叙述,不正确的一项是( )A.“一老河兵闻之”的“闻”与成语“闻风丧胆”的“闻”意思想同。

B.“适在枯水井前”中的“适”与成语“适可而止”的“适”意思不同。

C.两只落入水中的石兽,过了十多年,未被河水冲到下游,反而到了上游数里外处。

D.傅显知书达理,他看到小孩子有险情,急忙去找小孩子的父亲,小孩子才平安无事。

采莲曲唐·王昌龄荷叶罗裙一色裁,芙蓉向脸两边开。

乱入池中看不见,闻歌始觉有人来。

(1)诗歌第二句“芙蓉向脸两边开”用了衬托的手法,明写________,实则为了衬托出________之美。

(2)请赏析“乱”字的妙处。

2.阅读诗歌,回答问题竹里馆王维独坐幽篁里,弹琴复长啸。

深林人不知,明月来相照。

【译文】独自一人坐在幽深的竹林里,一边弹琴一边发出长长的啸声。

在这幽深的竹林里,无人陪伴,唯有明月似解人意,来相照映。

【作者简介】王维(约701~761),字摩诘,祖籍太原祁县(今山西祁县),唐代诗人、画家,官至尚书右丞,故世称王右丞。

其诗、画成就都很高,苏东坡赞他“味摩诘之诗,诗中有画;观摩诘之画,画中有诗”。

尤以山水诗成就为最,与孟浩然合称“王孟”。

晚年无心仕途,专诚奉佛,被称为“诗佛”。

著有《王右丞集》。

【主题思想】全诗描绘出一幅月夜竹林弹琴吟咏图,表现出一种悠然闲适的心境和自得其乐的情趣。

(1)“独坐幽篁里”的“幽”,“深林人不知”中的“深”,渲染了怎样的境界?(2)诗人独自在竹林里做了哪些事情?从中可以看出诗人怎样的性情?(3)这首诗借助景物描写,传达了诗人怎样的心情?3.阅读下面这首宋诗,完成后面小题。

南溪早春①杨还家五度见春容,长被春容恼病翁。

高柳下来垂处绿,小桃上去末梢红。

卷帘亭馆酣酣日,放杖溪山款款风。

更入新年足新雨,去年未当好时丰。

【注】①本诗是作者晚退职家居期间所作。

(1)诗人通过写柳树和桃树的什么特点来表现南溪早春的?(2)这首诗歌蕴含着诗人丰富的情感,请作赏析。

4.阅读诗歌,回答问题。

几处败垣③围故井,向来④一一是人家。

【注】①淮村:淮河边的村庄。

②戴复古:南宋著名江湖诗派诗人,曾从陆游学诗。
