38、itor语文(一)1.2.跳过(二)汗青”是史册的意思，这要追溯到纸张发明之前了。那时古人记事要用“竹简 ”，亦即用上好的竹自记写镌刻事情和文章，此一片片的竹即称“竹简 ”。竹简的制作并不简单，首先要选择上等的青竹（此“青竹 ”指绿色之竹），称其为“青 ”；然后，削成长方形的竹片，再用火烘烤一片片的青竹，一方面是为了便于书写，另方面也为干燥防虫。烘烤之时，本来新鲜湿润的青竹片，被烤得冒出了水珠，像出汗一样。这道烘烤青竹的工序就叫做“汗青 ”了。 “汗青 ”的原意是青竹出汗的工序，渐渐成了竹简的代名词了。从出土的古代竹简来看，长的竹简常用于书写儒家经典；短的竹简常用其记载诸子事迹及史传。因此“汗

39、青 ”代称竹简再演变，人们便地一步又将其代称竹简所记载的“史册 ”了。桃李.据汉朝韩诗外传记载，春秋时，魏国有个叫子质的大臣，他得势时曾保荐过很多的人。后丢官只身跑到北京，见到一个叫简子的人，向他发牢骚，埋怨自己过去培养的人在危难时不肯帮助他。简子听后笑着对子质说：春天种了桃树和李树，到夏天可在树下纳凉休息，秋天还可吃到可口的果实。可是，如果你春天种的是蒺藜，到夏天就不能利用它的叶子，而秋天它长出来的刺倒要扎伤人。你过去培养、提拔的人都是些不值得保荐的人，所以君子培养人才，就象种树一样，应先选好对象，然后再培植啊！古稀是中国人自古指七十高龄的说法。它源于唐代大诗人杜甫曲江二首诗，杜甫吟咏道：“

40、人生七十古来稀。”一千二百多年前的杜甫慨叹人生苦短，能活到七十岁，自古以来十分稀少安乐窝 出自宋 邵雍无名公传：所寝之室谓之安乐窝，不求过美，惟求冬暖夏凉敲竹杠清朝末年，鸦片走私十分严重，走私贩子为躲避关卡检查，挖空心思藏匿鸦片。水上走私的贩子把毒品密藏在竹制的船篙里，随船从水路运往各地。一天，一艘商船驶至浙江绍兴码头，缉私官带人上船检查，查遍了船舱的每个角落也没发现鸦片。 这时， 一个师爷吸着长烟筒，漫不经心地走到船艄，信手在撑船的竹篙上敲烟灰，敲得竹篙“嘟嘟 ”直响，别人没有反应，船主却吓得面色大变，知道师爷已看透了秘密，慌忙把这位师爷请到后舱，掏出大把的银子悄悄塞给他，请他关照，不要再敲

41、竹篙了。师爷得到银子便没说什么，随缉私人员下船去了。此后，“敲竹杠 ”便成了讹诈财物的代名词，并一直沿用下来。“敲竹杠 ”的来源，还有一种说法：四川山区，有钱人进山烧香时乘坐着一种用竹杆做的滑杆，滑杆由人抬着。走到半山腰抬滑杆的人就敲着滑杠，要求加工钱，否则就不抬人，乘坐滑杆的只好加钱。还有一说：清朝末年，市场上小额的买卖，以铜钱作为单位，店家接钱后便丢在用竹杠做的钱筒里，晚上结账时再倒出来，谓之“盘钱 ”，又称之为“盘点 ”。当时上海城里有家店铺，老板很不老实，陌生顾客进门，往往随意提价。每当伙计在接待顾客时，店主就敲竹杠一下，示意提价。（三）表示信心十足时用（十拿九稳）表示某人打小算盘时用

42、（小九九）表示某人干事麻利时用（三下五除二）表示一样东西两人平分时用（二一添作五）表示实实在在，不可更改时用（一是一，二是二）表示做事不考虑周到，干了再说时用（一不做，二不休）（4）小葱拌豆腐 一一 一青（清）二白和尚的住处 庙（妙）河边洗黄连 一一河（何）苦荷塘里着火 一一 藕（偶）燃（然）花盆里栽松树 成不了材（才）怀里揣篦子一一梳（舒）心黄河水一一难清（请）瞎子进烟馆 摩登。（摸灯）。空中布袋装疯。（装风）。宋江的军师无用。（吴用）。老太婆上鸡窝笨蛋。（奔蛋）。卖草帽的丢扁担-留神。（留绳）。哥哥不在家 少来。（嫂来）。外甥打灯笼照旧。（照舅）。雨打黄梅头倒霉。（倒梅）。半两棉花 免谈。

45、忙。（盲上加盲）。万岁爷流鼻血 正红。（朕红）。打破沙锅问到底。（纹到底）。西瓜地裹散步 左右逢源。（左右逢圆）。脱了旧鞋换新鞋 -改邪归正。（改鞋归正）。麻布袋草布袋一代不如一代。（一袋不如一袋）。碗底的豆子 历历在目。（粒粒在目）。卖布不带尺 存心不良。（存心不量）。民间传说无所不包一一某饺子馆广告 无所不包”本来指没有什么东西不被包括在内，也就是包容了事物的全部的意思，其中的 包”义为 容纳在里头这则广告用来指包饺子的包”，使得这个多义词的语义连接也很合理。（5）东风破.句句压韵（6）有一财主，父子花钱各捐了一个进士，心中十分得意，大年三十，在门前贴了一副对联，以示庆贺。联曰：父进士，子

46、进士，父子同进士；妻夫人，媳夫人，妻媳皆夫人。才人王某读罢，在对联上寥添数笔，其联顿成：父进土，子进土，父子同进士；妻失夫，媳失夫，妻媳皆失夫。财主见了又羞怒，只得把对联撕去。（7）口日（8）会徽图案形似汉字“世”，并与数字“2010 ”巧妙组合，相得益彰，表达了中国人民举办一届属于世界的、多元文化融合的博览盛会的强烈愿望。会徽图案从形象上看犹如一个三口之家相拥而乐，表现了家庭的和睦。在广义上 又可代表包含了 “你、我、他”的全人类，表达了世博会“理解、沟通、欢聚、合作” 的理念。会徽以绿色为主色调，富有生命活力，增添了向上、升腾、明快的动感和意蕴， 抒发了中国人民面向未来，追求可持续发展的创

47、造激情。（一）1 .折柳折柳一词最早出现在汉乐府折杨柳歌辞第一中：上马不捉鞭，反折杨柳枝。所以折柳是一支曲子名，所以 曲中闻折柳折柳”一词寓含惜别怀远”之意：在我国的古代，亲朋好友一旦分离，送行者总要折一支柳条赠给远行者。折柳”一词寓含 惜别”之意。我国 折柳送行”的习俗最早见于我国第一部诗歌总集诗经里 的小雅；采薇： 昔我往矣，杨柳依依；今我来思，雨雪霏霏 ”。古时柳树又称小杨 或杨柳，因 柳”与 留”谐音，可以表示挽留之意。离别赠柳表示难分难离、不忍相别、 恋恋不舍的心意。2 .这样一改，语句精炼多了。 但原诗中由 纷纷”路上“借问“牧童"四个意象组成的乡 村清明的特有意境也被破

48、坏了。所以说，从语句的精炼角度来看，修改是成功的；从 意境的提炼角度看，修改则是失败的。3 .直抒胸臆的句子是：千万恨，恨极在天涯。2,后三句写景，以山月、风水、落花和碧云的无情，与千万恨”、心里事”的有情相对照，突出思妇内心的怨恨和忧伤。（二）1 我们应该向那原学习他贫不丧志，立志求学的精神和他在学习上刻苦勤奋的精 神。书塾中的老师值得我们敬佩的是他免收那原的学费，不计报酬地教书，为下一代 无私奉献的精神魅力。2 .轻视怨恨.像这样用学习来损害自己，还不如不要学习。学习要永不满足，做人要谦虚，切忌傲气3 .的到现在你欺骗他，这是教育孩子欺骗人诚信，言出必行。答应别人的事一定要做到（三）许爹男

49、（四）安徒生的世界是如此丰富神奇，充满着诗与童话，充满着爱与感动，充满着美与悲剧。这个世界有着令人神往使人欲罢不能的魔力，它既能使我们远离世俗的世界，又能被我们亲切地理解；既能使我们听到来自天外上帝的脚步声，又能使我们感受到 自己的脚步声。从某种意义上说，世界儿童文学的太阳是从北欧丹麦的地平线上升起 来的。安徒生童话中所蕴涵的温暖的人性美、艺术美、幻想美已经温暖和照亮了全世 界一代又一代的小读者乃至大读者的心灵。经典是永恒的，常读常新的，安徒生所创 造的童话艺术世界也是如此。安徒生童话将不断地被年轻的童心所阅读和接受，从这 个意义上讲，安徒生是永生的。扩展阅读1 .想到的为人2 .后悔 愧疚伤

50、心 勇敢执着3 .贾佳：好开心哦，小强终于变回来了，我以后不要做这种傻事了，小强再怎么说也 是我的好朋友嘛，他总是帮我，别人欺负我的时候他给我解围，自己却挨了打，多好 的同学啊。张小强：好开心，好惭愧哦，我不该这么对待贾佳，她虽然把我变成了小狗，但她 也很着急的帮我想办法变回来，甚至想陪我变成小狗，多好的同学啊，以后再也不做 恶作剧了。（五）1。我以为那是一个自私的孩子是对生命的大不敬2 .时间的残酷人生的短暂世上有永远无法报答的恩情生命本身不堪一击的脆弱。3 .伤害了别人，就无法弥补；东西摔坏了，弄丢了，这可以弥补。一般可以弥补的 是物质上的，无法弥补的精神上的。4 .同意。因为连生他养他的
