八、阅读下面文段,回答问题。

谈骨气

我们中国人是有骨气的。

战国时代的孟子,有几句很好的话:“富贵不能淫,贫贱不能移,威武不能屈,此之谓大丈夫。”意思是说,高官厚禄收买不了,贫穷困苦折磨不了,强暴武力威胁不了,这就是所谓大丈夫。大丈夫的这种行为,表现出了英雄气概,我们今天就叫做有骨气。

我国经过了奴隶社会、封建社会的漫长时期,每个时代都有很多这样有骨气的人,我们就是这些有骨气的人,我们就是这些有骨气的人的子孙,我们是有着优良革命传统的民族。

当然,社会不同,阶级不同,骨气的具体含义也不同。这一点必须认识清楚。但是,就坚定不移地为当时的进步事业服务这一原则来说,我们祖先的许多有骨气的动人事迹,还有它积极的教育意义,是值得我们学习的。

南宋末年,首都临安被元军攻入,丞相文天祥组织武装力量坚决抵抗,失败被俘后,元朝劝他投降,他写了一首诗,其中有两句是:“人生自古谁无死,留取丹心照汗青。”意思是人总是要死的,就看怎样死法,是屈辱而死呢,还是为民族利益而死?他选取了后者,要把这片忠心纪录在历史上。文天祥被拘囚在北京一个阴湿的地牢里,受尽了折磨,元朝多次派人劝他,只要投降,便可以做大官,但他坚决拒绝,终于在公元1282年被杀害了。

孟子说的几句话,在文天祥身上都表现出来了。他写的有名的《正气歌》,歌颂了古代有骨气的人的英雄气概,并且以自己的生命来抗拒压迫,号召人民继续起来反抗。

另一个故事是古代有一个穷人,饿得快死了,有人丢给他一碗饭,说:“嗟,来食!”(喂,来吃!)饿人拒绝了“嗟来”的施舍,不吃这碗饭,后来就饿死了。不食嗟来之食这个故事很有名,传说了千百年,也是有积极意义的。那人摆着一副慈善家的面孔,吆喝一声“喂,来吃!”这个味道是不好受的。吃了这碗饭,第二步怎样呢?显然,他不会白白施舍,吃他的饭就要替他办事。那位穷人是有骨气的:看你那副脸孔,那个神气,宁可饿死,也不吃你的饭。

不食嗟来之食,表现了中国人民的骨气。

还有个例子。民主战士闻一多是在1946年7月15日被国民党枪杀的。在这之前,朋友们得到要暗杀他的消息,劝告他暂时隐蔽,他毫不在乎,照常工作,而且更加努力。明知敌人要杀他,在被害前几分钟还大声疾呼,痛斥国民党特务,指出他们的日子不会很长久了,人民民主一定得到胜利。毛主席在《别了,司徒雷登》一文中指出:“许多曾经是自由主义者或民主个人主义者的人们,在美国帝国主义者及其走狗国民党反动派面前站起来了。闻一多拍案而起,横眉怒对国民党的枪,宁可倒下去,不愿屈服。”高度地赞扬他表现了我们民族的英雄气概。

孟子的这些话,虽然是在2000多年以前说的,但直到现在,还有它积极的意义,当然我们无产阶级有自己的英雄气概,有自己的骨气,这就是决不向任何困难低头,压不扁,折不弯,顶得住,吓不倒,为了社会主义、共产主义建设的胜利,人们一定能够克服任何困难,奋勇前进!

1.“富贵不能淫,贫贱不能移,威武不能屈”一句语出_______,其中“淫”的意思是_____,“移”的意思是_____,“屈”的意思的是_______。

2.第一段文字作用是 _____。第二段文字通过引用古语来_____ 。

第四段中_____一句起引出下文的作用。五、六两段的表达式分别是_____、_____ 。

“留取丹心照汗青”中“汗青”指代_____,用的是_____手法。

五、六两段印证了孟子的话_____,进而证明_____ 。

第七段写了_____的事实,从_____的角度证明论点。

3.从论证方法上看,七段先_____,后 _____,接着用八段这一_____段加以小结。

4.九段中对闻一多之例的叙述采用了_____的记述顺序,是为了突出_____。

这段先叙述 _____的事实,再 _____,使说理充分。

5.五到九段列举的三个事例顺序能否颠倒,为什么?

答:

九、阅读课外选文,回答问题。

学会认输

①国人素爱面子,于输赢上比较认真。

②虽说胜败乃兵家常事,但有“胜者为王,败者为寇”的规则在上,赢了谁不高兴?至于输了的一方,郁闷、伤心、一蹶不振的不少。

③逐鹿中原,争霸天下之际,失败就意味着Game over。以至于“力拔山兮气盖世”的项羽在兵败乌江之时,当即拔剑自刎。因为他知道为寇者的悲惨命运。人们也往往认为项羽是失败了的英雄,起码李清照是这么认为的。这位杰出的女词人,也作了一首杰出的诗:“生当做人杰,死亦为鬼雄。至今思项羽,不肯过江东。”我是很佩服“生当做人杰,死亦为鬼雄”的豪情的。好男儿自当有凌云壮志,轰轰烈烈地活一场。然而,对于项羽不肯过江东一事,杜牧有诗云:“胜败兵家事不期,包羞忍耻是男儿;江东子弟多才俊,卷土重来未可知。”我更赞同杜牧的观点,要批评项羽:没有学会认输!

④争霸天下的大事之中,尚且有认输的学问;在平常的生活中,我们更要学会认输!

⑤成功是人人想要的,但是,成功是不易的。生活的内容极其丰富,生活的领域极为宽广,没有人会在生活的每一个领域里总是一帆风顺。我们遇到的挫折和失败的次数要比获得成功的次数多得多。挫折会一次又一次地找上我们。连爱迪生这样的科学家,当他研究灯泡时,挫折也要找他上千次的麻烦,它又怎么肯放过普通的人呢?

⑥学会认输,首先要能对所面临的糟糕的形势做出正确的判断。形势还未绝望时,绝不能轻言认输。某年高考的作文题目,给了一组漫画。画上的人挖井,每处所挖距离出水都不远,也许只要再挖一镐就可以成功了,但是其人认为此处无水而放弃。这漫画给我的印象极深刻。就说项羽吧,如果轻言认输,又怎么会有破釜沉舟之举,谱写出以少胜多的辉煌篇章呢?但形势无望之时,却必须放弃!还说项羽,四面楚歌,身边仅余28勇士,还不肯渡江而去,令人嗟叹。假如当初项羽肯听从建议,渡江东去,再集合江东健儿,与刘邦一决高低,历史就可能另写了。形势如果绝望了,那么就痛痛快快地认输吧!比如鸡蛋与石头,相碰的结果当然是鸡蛋输。如果,一直拿鸡蛋往石头上扔去,岂不愚蠢?

⑦认输之后,重要的是尽快清除失败带来的消极影响。比如,行路之人一不小心摔倒了,摔倒就是摔倒了,没什么,重要的是,赶紧站起来吧!不要一直坐在地上,怨天尤人。站起来,拂去身上的泥尘,继续赶路才对。当年东南亚经济危机袭来,许多富翁一夜之间沦为穷人,一时传来不少富翁打工的消息。我是很佩服这些打工的富翁的。打工,说明他们已经坦诚地认输,而且已经成功清除了失败带来的消极影响,改变了富贵时的那些锦衣玉食的习惯。不打工,犹在说“当年我是多么富有”之类的话,再坚持要过锦衣玉食的生活,岂不令人齿冷?

⑧认输之后,还得再来!比如求职,让人拒聘了,之后仍要找工作;比如吃饭,一次被噎着,之后饭仍是要再吃的。下棋的人经常认输,没有关系嘛,输了一盘,再来一盘呀!只要人还活着,棋总是有得下的。输了一次之后就再也不下棋的人,永远无法进入高手境界。我们的创业或许会失败,我们的理想或许一时无法实现,但是我们的人还活着。活着真好!活着就有无数的机会,重新来过,或另辟捷径都好。

⑨失败是成功之母。但记着,在找到成功这个宝贝儿子之前,首先要学会认输!

1.本文的中心论点是什么?

答:

2.选文⑥⑦⑧三段分别论证了什么观点?三段间的层次关系是什么?

答:

3.请你简要分析第⑤段的论证过程。

答:

[生活常识]

数九

“数九”习俗起源于何时,现在还没有确切的资料。不过,至少在南北朝时已经流行。梁代宗懔《荆楚岁时记》中就写道:“俗用冬至日数及九九八十一日,为寒尽。”数九寒天,就是从冬至算起,每九天算一“九”,一直数到“九九”八十一天,“九尽桃花开”,天气就暖和了。

劳动人民经历了千百年与风雪严寒的搏斗,根据长期的实践经验,创造出许多记叙数九期间寒暖变化规律的“九九歌”。如北方流行的九九民谣:

未从数九先数九,一九二九冰上可行走。三九四九掩门叫黄狗。五九六九开门缩颈走。七九河开,八九雁来。九九又一九,犁牛遍地走。

顾禄《清嘉录》上记载有一首“数九歌”,十分风趣地描写了古代人们过冬的情形:

一九二九,相唤弗出手(手都因怕冷而缩在面袍里);三九二十七,篱头吹 篥(寒风刮在篱笆头上,像吹 篥一般);四九三十六,夜眠如露宿(睡在被窝里像睡在野地里一样);五九四十五,穷汉街头舞。不要舞,不要舞,还有春寒四十五(穷人衣薄,起舞取暖);六十四,苍蝇垛屋(透露出一点暖意了);七九六十三,布袖两肩摊(天暖,厚衣服可以披在肩上了);八九七十二,猫狗躺凉地;九九八十一,穷汉受罪毕,刚要伸脚眠,蚊虫跳蚤出。

在古代社会里,穷人过冬尤其受罪。

我国地域广阔,各地“九九歌”不尽相同;但大同小异。有一首较通俗的民谣是这样的(北京版):

一九二九不出手。三九四九冰上走。五九六九沿河看柳。七九河开,八九雁来。九九加一九,犁牛遍地走。

俗谚有“头九暖,九九寒”,人们发现如果起头九天暖和,则跟着来的整个冬天都会特别冷。故说“第一莫贪头九暖,连绵雨雪到冬残”。《燕京岁时记》中说:“冬至三九则冰坚。”意思是,从三九起就进入数九寒天中最冷的阶段了。《京房易占》说:“冬至之后,三十日极寒。”,“冬至后第三戌,为腊月最冷者。”后来,一般人们都认为三九天是最冷的,但是事实上,四九才是寒冬中一段最冷的时间。只不过刚进三九的头几天,寒暖变化大,一下暴冷,身体不太适应,显得格外寒冷,而到四九,虽然温度比三九低,但温差变化小,便感觉不如二九进入三九时这么冷了。

自冬至起,三四九刚好在二十四节气的大寒附近。

①傅雷先生是中国文学艺术史上著名的翻译大师,他以卷帙(zhì,书画外面包着的卷套)浩繁、技术精湛的译著,博古通今、学贯中西的学术修养,被学术界称为一两个世纪也难得出现一位的巨匠。

②他16岁时赴法留学学习艺术理论,刻苦攻读,得以观摩了解世界级艺术大师的作品,大大提高了他的艺术修养。

③他1931年秋回国,曾任教于上海美专,因不愿与世俗同流合污而闭门译书,几乎译遍法国大师级作家伏尔泰、巴尔扎克、罗曼·罗兰等人的重要作品,并把法国著名艺术史家丹纳的《艺术哲学》引进中国人的视线,且形成了自己的翻译风格,堪称“傅译”。傅雷艺术造诣深厚,不仅在翻译方面,而且在文学、绘画、音乐等各个艺术领域,都有极渊博的知识。他自己没有弹过钢琴,却能培养出傅聪这样一位世界知名的钢琴家。他没有学过专业美术绘画,却能够赏识当时并不出名的著名国画家黄宾虹,显示出其独特高超的艺术鉴赏力。

④人们不免会对傅雷这样的“天才”产生兴趣。有人说,傅雷的成功来源于他的寂寞。傅聪曾经这样评价过他的父亲:“我父亲是一个文艺复兴式的人物,一个寂寞的先知,一头孤独的狮子,愤慨、高傲、遗世独立……”傅雷自己也曾一再告诫儿子傅聪,“要耐得住寂寞”。著名翻译家、傅雷先生的好友杨绛女士在《忆傅雷》中讲道:“傅雷不止一次在钟书和我面前自比为‘墙洞里的小老鼠’。”“墙洞里的小老鼠”,有“躲进小楼成一统”之意,其内涵还是寂寞。

⑤寂寞是一种智慧。善于发现的雕塑家罗丹有独到的心得:“艺术是孤独的产物,因为孤独比快乐更能丰富人的情感。”这恐怕才是一切有成就的人无不喜欢寂寞的真正原因。鲁迅就有这样奇妙的体验,“当我沉默的时候,我觉得很充实;当我开口说话,就感到了空虚。”

⑥寂寞是一种磨炼。真正的寂寞是人们内心深处演绎、裂变、积淀的情愫。

⑦寂寞是一种享受。任何事物都是相对的,寂寞不仅是痛苦,对一些心存大志、特立独行的人来说,孤独、寂寞、隔离,有时确是一种至高享受。

⑧当今社会,竞争激烈,想成才的人特别多。但首先得问一问自己,我能不能坚持我的初衷?现在热闹场面的诱惑实在是多:结婚宴请,同学聚会,生日派对,母校校庆,考察学习,出境旅游,扑克麻将,彩票足球,度假休闲。稍不注意,就会被聚会缠身,被喧哗左右,被欢乐包围。

⑨寂寞无价。对当代人来说,更是如此。

1.阅读全文后,概括文章的中心论点。

2.文章①至③段讲述傅雷先生的事例,其作用有二:一是从行文结构上 ,二是为证明观点 。

3.下面是1954年9月4日傅雷先生写给儿子傅聪的一段话,结合这段话并联系上文谈谈傅雷所以成为一代文学巨匠的原因,并说说你从中得到的启示。(100字以上)

你的随和脾气多少得改掉一些。对外国人比较容易,有时不妨直说:我有事;或者:我要写家信。艺术家特别需要冥思默想。老在人堆里(你自己已经心烦了),会缺少反省的机会;思想、感觉、感情,也不能好好地整理、归纳。

[生活知识]

暑伏

所谓的“伏天儿”,就是指农历“三伏天”,既一年当中最热的一段时间。

三伏天出现在小暑与大暑之间,是一年中气温最高且又潮湿、闷热的日子。

可以这样理解:“伏”就是天气太热了,宜伏不宜动,三伏是中原地区在一年中最热的三、四十天,三伏是按农历计算的,大约处在阳历的7月中旬至8月上旬间。

每年入伏的时间不固定,中伏的长短也不相同,需要查历书计算,简单地可以用“夏至三庚”这4字口诀来表示入伏的日期,即从夏至后第3个“庚”日算起,初伏为10天,中伏为10天或20天,末伏为10天。我国古代流行“干支纪日法”,用10个天干与12个地支相配而成的60组不同的名称来记日子,循环使用。每逢有庚字的日子叫庚日。庚日的“庚”字是“ 甲、乙、丙、丁、戊、己、庚、辛、壬、癸”10个天干中的第7个字,庚日每10天重复一次。从夏至开始,依照干支纪日的排列,第3个庚日为初伏,第4个庚日为中伏,立秋后第1个庚日为末伏。当夏至与立秋之间出现4个庚日时中伏为10天,出现5个庚日则为20天。看来,庚日出现的早晚将影响中伏的长短,所以,出现了有些年份伏天30天,有些年份伏天40天的情况。

由于三伏天是全年中天气最热,气温最高,阳气最盛的阶段,在这一阶段,人体腠理疏松,经络气血流通,有利于药物的渗透与吸收,而庚日又与肺金有关(庚日为金,属大肠,大肠与肺相表里),为温煦肺经阳气,驱散内伏寒邪的最佳时机。加之精心选取有温经散寒、化痰平喘作用的膀胱经及督脉腧穴进行敷贴,相得益彰,共收扶正祛邪之功,故而能起到防病治病的作用。

三伏天,一伏是十天,这是按照天干的十数去计算的。所以,划分三伏天,就是:夏至之后的第三个天干的庚日,为第一伏的开始天。比如,的夏至,是西历年的6月21日,这一天的天干日是辛日,28天之后,就是第三个庚日,所以,20的7月20日,就是第一伏的开始;十天之后,又是个庚日,也就是7月29日,就进入了第二伏;十天之后,又是一个庚日,也就是8月9日,就进入了第三伏。这就是说,每年进入三伏天之后,都是很热的,特别是第三伏的十天,是最热的。

十、(一)1. 义正辞严地揭露国民党反动派令人震惊的罪行。2. 三个都是副词。强调李先生的行为是一个中国人的正当行为,是正义的。3. “光明正大”、“偷偷摸摸”。用对比揭露国民党反动派卑劣无耻到极点。4. “这实在是不像话。”原句语气有力,痛斥敌人;改后轻描淡写,语气无力。

(二)1. C 2. A 3. C 4. B 5. 生前的最后一次 6. 特务 遭受屠杀的昆明青年学生 李公朴被暗杀 “一·二一”昆明青年学生反对内战被屠杀

十一、1.一个人要想在事业上有所成就,就必须耐得住寂寞。2.引出论述的观点 提供事实论据 3.傅雷先生能够在成名之后不但自己仍然坚守初衷,享受寂寞,坚持自己的追求,而且还教育自己的儿子,要经常享受寂寞,在寂寞中冥思默想。这就是他之所以成为一代文学巨匠的原因。我们应该向傅雷先生学习,不受纷繁热闹生活的诱惑,坚守心灵和生活的寂寞,多学习,勤思考,努力积累知识,提高思想和认识水平。

9.当两艘船平行航行时,在它们的船舷中间就好像有一沟。在普通的沟里,沟壁不动,水在动。这里正相反,是水不动水沟壁动。在这条能动的沟的狭窄部分,由于水相对船的流速较大,使得两艘船的相对两侧受到的压力比两船外侧部分受到的压力小,从而使两船相向运动,发生撞船事故。

10.原来,混合阀像个三通管,冷水管比较粗,在汇合点附近突然变细.

混合水 冷水

Australia has a lot of lovely animals. You cannot find them anywhere else

in the world. The most famous ones are kangaroos and koalas(树袋熊). The kangaroo

is the symbol of Australia. They have large eyes and ears. They don’t walk, they

jump. They use their strong back legs. They can jump at up to 74 kilometers per

hour. They can go over nine meters in one jump!

Kangaroo mothers have pouches(育儿袋) to carry their babies. The babies stay

inside to get milk and keep warm. Kangaroos are everywhere in Australia. They

are on TV, in books and in the shops. The government even wants to put them on

passports(护照).

But do you know that millions of kangaroos are killed every year? There are

too many of them.

There are about 20 to 25 million kangaroos in Australia. That’s more than

the number of people in the country! Some kangaroos go hungry because there is

not enough food to eat. They break into farms for food. Farmers are very angry

with them. The koala is another famous Australian animal. They look like bears,

and have small eyes and big noses. They eat leaves from eucalyptus, where they

spend most of their time. Koalas have a special smell. They use it to mark their

home—“This is my place, you can’t come in!” Like kangaroos, a koala baby lives

in its mother’s pouch. But koalas have fewer places to live in. There are about

100,000 koalas in Australia. There is a law to keep them safe.

( )41. Kangaroos and koalas are the most famous animals in Australia

because _______.

A. there are not many of them B. they can’t live in other countries

C. we can’t see them in any other country except Australia

D. they are lovely animals

( )42. Which of the following is WRONG about kangaroos?

A. They can run at up to seventy-eight kilometers per hour.

B. They have large eyes and ears.

C. Kangaroo mothers have pouches to carry their babies.

D. There are many of them in Australia.

( )43. Why does the Australian government kill some kangaroos each

year?

A. They can make more money. B. Kangaroos break into farms for food.

C. Kangaroos do not have enough food to eat.

D. There are more kangaroos than people.

( )44. What do koalas use to mark their home?

A Their footprint. B. Their sound. C. Their fur. D. Their smell.

( )45. What is the similarity(相同之处)between a kangaroo and a koala?

A. There are too many of them in Australia.

B. They keep their babies in the mother’s pouch.

D. They can jump very high.

C

The size and shape of your ears show your character more than any other

parts of the face. Other parts of the face change shape as we get older, but

ears do not change their shape. They only change in size.

Reading people’s character from their ears is an old science. In very old

times people thought that a person with big ears had a good and generous

character. They thought that a person with pale (nearly white), small ears was

dangerous. They also thought that the shape of the ear showed whether a person

was musical or not. Today, too, many people believe that the size and the shape

of the ear help you know if a person is musical.

Ears are all different, and each characteristic has a meaning. Next time

when you look at a person, see if his ears are large or small. Look at the

lobes( the lowest part of the ear). Are they attached(连着) to the face? Ears that

are always red mean a person may easily get angry, or he/she just has high blood

pressure(高血压). Ears that are always cold and pale mean a person has a nervous

character. And a big inside hole of the ear means a person is musical.

( )46.In the old times people might ask for help from a person

with____________.

A. red ears B. big ears C. small ears D. pale ears

( )47. The passage is mainly about ___________.

A. the size of our ears B. musical ears

C. ears which related to characters D. our faces and ears

( ) 48. From the passage, we know ___________ change shape as we get

older.

A. ears B. hair C. eyes D. teeth

( ) 49. We can guess Beethoven may have __________________.

A. pale ears B. white ears

C. small ears D. ears with a big inside hole

( )50. If you are often late for school, you may find the ears of your

teacher _________.

A. get bigger B. get smaller C. get colder D. get redder

According to a new survey(调查), student safety has become a big problem.

Nearly 50% of students say they are worried about robbery(抢劫) on the way to and from school. Now in many big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens. Chen Haoyu, a teacher at Beijing No. 25

Middle School, gives young students advice on how to deal with danger.

If you are robbed Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later.

If you are in a traffic accident

If a car hurts you. you should remember the car number. If it is a bicycle,try to call your parents before you let the rider go. This is because you don’t know how seriously you are hurt.

If it is raining hard and there is lightning(闪电)Don’t stay in high places and stay away from trees.

When there is a fire

Get away as fast as you can. Put wet things on your body and try to find an exit. Do not take the lift.

If someone is drowning(溺水)

If you can’t swim, don’t get into the water. Cry out for help.

Remember that danger is never as far away as you think. Take care of

yourself at all times!

( )36. Why do students like the self-protection lesson?
