二、阅读理解(53分)
(一)比较阅读(16分)
[甲]最妙的是下点小雪呀。看吧,山上的矮松越发的青黑,树尖上顶着一髻儿白花,好像日本看护妇。山尖全白了,给蓝天镶上一道银边。山坡上,有的地方雪厚点儿,有的地方草色还露着;这样,一道儿白,一道儿暗黄,给山们穿上一件带水纹的花衣;看着看着,这件花衣好像被风儿吹动,叫你希望看见一点更美的山的肌肤。等到快日落的时候,微黄的阳光斜射在山腰上,那点薄雪好像忽然害了羞,微微露出点粉色。就是下小雪吧,济南是受不住大雪的,那些小山太秀气。
[乙]车过西泠桥以后,驶行于两边山岭林木连接着的野道中。所有的山上,都堆积着很厚的雪块,虽然不如瓦屋上那样铺填得均匀普遍,那一片片清白的光彩,却尽够使我感到宇宙的清寒、壮旷与纯洁!常绿树的枝叶上所堆着的雪,和枯树上的很有差别。前者因为有叶子衬托之故,雪块堆积得大一点,远远望去,如开满了白的山茶花。后者,则只有一些小小的雪片能够在上面粘着不落下去,与刚开花的梅李树绝对的相似。真的,我开始几乎把那些近在路旁的几株错认了。野道上半黄或全赤了的枯草,多压在两三寸厚的雪褥下面;有些枝条软弱的树,也被压抑的歪歪倒倒的。路上行人很稀少。道旁的屋里,时见有衣饰朴实而笨重的老人、童子,在围着火炉取暖。看了那种古朴清贫的情况,仿佛令我忘怀了我们所处时代的纷扰了。

(2)远远望去,如开满了白的山茶
12、古代诗词中有许多描写雪景的名句,你掌握的有多少?请回忆一下,写出一句。(1分)
(二)比较阅读(17分)
[甲]桃树、杏树、梨树,你不让我,我不让你,都开满了花赶趟儿。红的像火,粉的像霞,白的像雪。花里带着甜味儿;闭了眼,树上仿佛已经满是桃儿、杏儿、梨儿。花下成千成百的蜜蜂嗡嗡地闹着,大小的蝴蝶飞来飞去。野花遍地是:杂样儿,有名字的,没名字的,散在草丛里,像眼睛.像星星,还眨呀眨的。
[乙]暖国的雨,向来没有变过冰冷的`坚硬的灿烂的雪花。博识的人们觉得他单调,他自己也觉得不幸否耶?江南的雪,可是滋润美艳之至了;那是还在隐约着的青春的消息,是极健壮处子的皮肤。雪野中有血红的宝珠山茶,白中隐青的单瓣梅花,深黄的磬口的腊梅花;雪下面还有冷绿的杂草。蝴蝶确乎没有;蜜蜂是否来采山茶花和梅花的蜜,我可记不真切了。但我眼前仿佛看见冬花开在雪野中,有许多蜜蜂们忙碌的飞着,也听得他们嗡嗡地闹着。

(三) 秋 颂(20分)
罗兰
⑴秋天的美,美在一份明澈。
⑵有人的眸子像秋,有人的风韵像秋。
⑶代表秋天的枫树之美,并不仅在那经霜的素红,而更在那临风的飒爽。
⑷当叶子逐渐萧疏,秋林显出了它们的秀逸。那是一份不需任何的点缀的洒脱与不在意俗世繁华的孤傲。
⑸最动人是秋林映着落日。那酡红如醉,存托着天边加深的暮色。晚风带着清澈的凉意,随着暮色浸染,那是一种十分艳丽的凄楚之美,让你想流几行感怀身世之泪,却又被那逐渐淡去的醉红所慑住,而情愿把奔放的情感凝结。
⑹曾有一位画家画过一幅霜染枫林的“秋院”。高高的枫树,静静掩住一园幽寂,然后重门深掩,看不尽的寂寥,好像我曾生活其中,品尝过秋之清寂。而我仍想悄悄步入画里,问讯那深掩的重门,看其中有多少灰尘,封存着多少生活的足迹。
⑺最耐寻味是秋日天宇的闲云。那么淡淡然,悠悠然,悄悄远离尘间,对俗世悲欢扰攘,不再有动于衷。
⑻秋天的风不带一点修饰,是最纯净的风。那么爽俐的轻轻掠过园林,对萧萧落叶不必有所眷顾——季节就是季节,代谢就是代谢,生死就是生死,悲欢就是悲欢。无需参预,不必留连。
⑼秋水和风一样的明澈。“点秋江,白鹭沙鸥”,就画出了这份明澈。没有什么可忧心、可紧张、可执著。“傲杀人间万户侯,不识字烟波钓叟”。秋就是如此的一尘不染。
⑽“闲云野鹤”是秋的题目,只有秋日明净的天宇间,那一抹白云,当得起一个“闲”字。野鹤的美,澹如秋水,远如秋山,无法捉摸的那一份飘潇,当得起一个“逸”字。“闲”与“逸”,那正是秋的本色。
⑾也有某些人,具有这份秋之美。也必须是这样的人,才会有这样的美。这样的美来自内在,他拥有一切,却并不想拥有任何东西。那是由极深的认知与感悟所形成的一种透澈与洒脱。
⑿秋是成熟的季节,是收获的季节,是充实的季节,却也是澹泊的季节。它饱经了春之蓬勃与夏之繁盛,不再以受赞美、被宠爱为荣。它把一切的赞美与宠爱都隔离在澹澹的秋光外,而是愿做一个闲闲的、远远的、可望而不可及的秋。

我说道:“爸爸,你走吧。”他往车外看了看说:“我买几个橘子去。你就在此地,不要走动。”我看那边月台的栅栏外有几个卖东西的等着顾客。走到那边月台,须穿过轨道,须跳下去又爬上去。父亲是一个胖子,走过去自然要费事些。我本来要去的,他不肯,只好让他去。我看见他戴着黑布小帽,穿着黑布大马褂,深青布棉袍,蹒跚地走到铁道边,慢慢探身下去,尚不大难。可是他穿过铁道,要爬上那边月台,就不容易了。他用两手攀着上面,两脚再向上缩;他肥胖的身子向左微倾,显出努力的样子,这时我看见他的背影,我的泪很快地流下来了。我赶紧拭干了泪。怕他看见,也怕别人看见。我再向外看时,他已抱了朱红的橘子往回走了。过铁道时,他先将橘子散放在地上,自己慢慢爬下,再抱起橘子走。到这边时,我赶紧去搀他。他和我走到车子上,将橘子一股脑儿放在我的皮大衣上。于是扑扑衣上的泥土,心里很轻松似的。过一会说:“我走了,到那边来信!”我望着他走出去。他走了几步,回头看见我,说:“进去吧,里边没人。”等他的背影混入来来往往的人里,再找不着了,我便进来坐下,我的眼泪又来了。

平原风雪夜
宝泉
①晚上9点过去,父亲还没回来,母亲就叫我们吃饭,她自己却不吃。我那年15岁,稍微知道些世事,也跟母亲一块儿不吃饭。我不过大体上做个样子,母亲便称赞了我的懂事。
②深夜11点多,独轮车声吱吱呀呀响起来,愈来愈迫近,母亲说,你父亲回来了,快去接,我跑出院门,见父亲推着独轮车已经来到胡同口上,语文试题《第二单元复习测试(B卷)》。
③喝过菜汤,暖过肚子,父亲对母亲说:“我还得推一趟。这回买了500斤煤,一次推不回来,剩下的堆在南桥口,夜里不推别人就弄走了。”
④母亲说:“让泉儿跟你一块去吧。”
⑤我推空车出门去,父亲在后面跟着。南桥口离家五里路,若在白日,这段路不当回事的;可这回是夜间,眼皮好像粘住一样。感觉到脖颈里星星点点的凉,手一摸是水,知道下雪了,风也饿狼似的吼起来。
⑥大平原上夜间下雪气势浩大,暴风雪只有到了大平原上才得以横扫一切地逞强。
⑦雪原反射出晶莹的清光,近处的树木、草丛,都看得清楚,但在心理上却感到更冷,好似雪把剩余的一点热量都反射到九霄云外。走过一段路,父亲要我坐上车盘。但坐着不动更冷,只好又跳下来走路。
⑧到了南桥口,父亲停下车子,在一个凸起的坟头样的东西上扒掉雪,下面露出煤来。用麻袋装了两袋子,大概200多斤,抬到车盘上,父亲便驾起车把推行,我在前面用一根麻绳拉,是顺河堤往回走。偶尔回头看去,见父亲的身体总是不停摇摆,以便维持独轮车平衡。
⑨独轮车不好推,原因是独轮不稳,推车人左一脚右一脚地走,好比船家左一篙右一篙地撑,车头便左一下右一下地摆;而且车轮从辐条到轮箍全由木制,轮箍由几块弧形合成,用久了结合处会出现缝隙,轮子不再圆整,每转一圈就跳一下,砸得土路上起一排小坑。
⑩由此显现出驾驭的难处,推车人既要将车把提起,同时又要维持车盘的平衡,然后才是将车子推向前方。
走过一段路,父亲说歇歇吧。我回转跟父亲坐在一起,用毛巾给父亲擦汗。父亲头上热气腾腾,头皮上汗水淋漓,头发梢则硬得扎手,原来是边出汗边结冰的。父亲的衬衣也湿透了,濡湿了棉衣里子,他敞开怀,只一小会儿,棉衣里就结成冰,铁样的硬,指甲敲上去发出冷冷的金属声响。父亲说不敢久坐,接着又一起推拉。我再三要替父亲推一会儿,他答应了。
当我驾起车把,才知道那两麻袋煤不好推。我两手冻得麻木,根本握不牢车把,更难保持平衡,在前面拉车的父亲感觉到车子不稳,要我放下,就在放下的刹那间,车子一歪头从河堤滑下堤坡,我使劲让车子停下,却给车子拉下坡,急得父亲大喝:“松手,快松手!”
我如梦初醒,刚松手,车子同煤就箭一般地冲向河心。车子终于给一棵大树挡住了,两麻袋煤却窜到激流里。父亲吃力地将车子拖到岸上,重重叹了口气,说:“没啥,下回就会了。”
为了表示负疚,我请父亲坐车,我推着。那场雪下得很大,50年代经常有那么暴烈的雪。轮子在路上轧出痕印,走不多远便被白雪掩埋,大地上依旧纯净无痕,回归原始太初般的混沌一气,像根本没发生过什么一样。回到家里,父亲说煤给人弄走了,其余不再说。
那夜的故事,至今也只是我们父子知道。先前因为我的逃学父亲打过我,我暗中记仇,但自那夜之后,这一切都冰释雪消了。
如今,那河堤已经垫高加宽,铺上石子柏油,汽车、拖拉机如飞地往来,当年的故事掩埋其下。我固执地认为,汽车的轮印是那年隆冬辙痕的延长。如今父亲已是风烛残年,行将长伴泥土,一个活的历史证人就要去另一个世界。
父母给了我的童年数不清的磨难,却没有给我吃牛奶巧克力,我知道他们没有这些,因而并不怨恨;相反,在他们为生计奔波之时,我在一旁尽己所能地出过力,这便自小知道物品来之不易,一生中不敢暴殄天物。
他们无力给我物质享受,却给了我丰富的精神营养,也给了我自食其力的机会,对于我,这就够了。自己种树结的果子,那滋味才分外香甜。
10.给下列加粗的字注音。(4分)
轮箍( ) 驾驭( ) 濡湿( ) 暴殄天物( )
11.文章描写平原夜间雪景有什么作用?(3分)
12.作者在第 段具体描述了父亲歇息时的`一系列情景,字里行间表明了作者对父亲的深情。读后,你有什么感受?写在下面。(6分)
13.你怎样理解第 段中“先前有因为我的逃学父亲打过我,我暗中记仇,但自那夜之后,这一切都冰释雪消了”?(5分)
14.作者说,父母“给了我丰富的精神营养,也给了我自食其力的机会”你认为这“精神营养”指什么?“自食其力”又指什么?(6分)
15.你怎样理解“自己种树结的果子,那滋味才分外香甜”一句的深刻含义?(6分)

23.B由后半句中的didn’t可知前半句也用一般过去时,故排除C、D两项;didn’t后接动词原形,又排除A项。故选B项。
24.Dby oneself “独自”,故第一个空填反身代词himself;答语句意为“不,他的小妹妹和他在一起”。由句意可知第二个空填人称代词he的宾格him。
25.B由时间状语in 2005可知本句为一般过去时,be动词用was或were;空格后为单数名词,故be动词用was。
26.A“with+名词+形容词”常在句中作伴随状语,open可作形容词,意为“开着的”。

28.C“on one’s way to+地点名词”意为“在某人去……的路上”,故选C。29.Cnot...any more意为“不再……”,相当于no more。30.A由often可知前半句为一般现在时;由yesterday可知后半句为一般过去时。
31.Dtell sb.not to do sth.“告诉某人不要做某事”,故排除A、C两项;由this morning和主语she可知第二个空用be的过去式was。32.Bas usual是固定短语,意为“照例,像往常一样”。

38.Cgive sth.to sb.给某人某物。39.Bwant sb.to do sth.想让某人做某事。40.Bmany “许多”,修饰可数名词复数。

(2)用天平测量小石块的质量,右盘中的砝码和标尺上的游码如图甲所示,则小石块的质量为_______g。(3)如图乙所示: a.往烧杯中加入适量的水,把小石块浸没,在水面到达的位置上作标记; b.取出小石块,测得烧杯和水的总质量为153g;
c.往烧杯中加水,直到标记处,再测出此时烧杯和水的总质量为183g; d.计算出小石块的体积为________cm3。(4)用密度公式计算出小石块的密度为________ g/cm3。四.计算题(24题6分,25题9分,共15分)
24.(2012江西)我省富“硒”的矿泉水资源非常丰富.如果要将其开发为瓶装矿泉水,且每瓶净装550g,则:
(1)每个矿泉水瓶的容积至少要多少ml?(2)若用该矿泉水瓶来装家庭常用的酱油,装满后至少能装多少ml的酱油?
(ρ矿泉水=1.0×103kg/m3,ρ酱油=1.1×103kg/m3)
25.有一质量为5.4千克的铝球,体积是3000厘米3,试求这个铝球是实心还是空心?如果是空心,则空心部分体积多大?如果给空心部分灌满水,则球的总质量是多大?(铝=2.7×103千克/米3)
26、一个瓶子最多能装2kg的水。求:(1)该瓶子的容积;(2)用该瓶子装食用油,最多能装多少千克。(ρ水=1.0×l03kg/m3,ρ油=0.9×l03kg/m3)

21.(1)将游码移至标尺的零刻度线;(2)调节平衡螺母,使指针指到分度盘的中央刻度 三.实验题
22.(1)水平桌面上;平衡螺母(2)BCA(3)40;1.125;1.125×103 23.(1)平衡螺母(2)62
(3)30
(4)2.07(或2 或2.1)四.计算题 24.(1)V水=m水水=550g3
=550cm=550mL,31g/cm所以矿泉水瓶的容积至少为550ml(2)V酱油=V瓶=V水=550ml 装满后至少能装酱油550ml 25.(1)铝球中铝的体积为: V铝=m球/ρ铝=5400g 2.7g/cm3=2000cm3<3000cm3,所以这个铝球是空心的;(2)空心部分的体积:
V空=V球-V铝=3000cm3-2000cm3=1000cm3,(3)空心部分灌满水后,水的质量:
m水=ρ水V水=1g/cm3×1000cm3=1000g,此时球的总质量:
m总=m水+m铝=1000g+5400g=6400g.
答:这个铝球是空心的,空心部分的体积为1000cm3,空心部分灌满水时球的总质量是6400g.
