Remember a singing contest
National Day a few days ago the teacher told us in class at the meeting: "Schools to be held singing contests, competition in our class song was 'Let us Dangqi paddle', we go back to practice more than sing and strive to take a good ranking." Listening the teacher, then we would quickly empty practice the song until it sing by heart.
Competition this day has finally come. Lunch at noon, I excitedly carrying a school bag to school rush, just Jinjiao Men saw a lot of students on campus had already been sitting, and so I quickly ran into the classroom, to lay down their bags, pick up the benches along with his fellow students to join campus ran to find the location of our class, neatly seated.
Race started, the first play is the 23 classes, they sang "Beijing welcomes you", "Beijing welcomes you, the sun-sharing breath, yellow ground, refresh results ---- dream there will be a miracle." Listening to This is exciting, the familiar song, I remembered long ago in our country, the Olympics, I think of athletes in the arena fight scene, I think of the five-star red flag, the champions proud smile -. Finished singing, I and everyone energetically Pai Zhaoshou for them to cheer, cheer for our country.
Race quickly, quickly turn our class play. We are one by one wearing clean uniforms, with bright red scarf, behind a neat team, head held high valiantly turn. Music sounded, we sing out loud. "Let us Dangqi sculls, boat pushing children wave -" The Phantom of melodious sounds, loud voice that I think we like to a boundless sea, the students one by one little boat struggling to forging ahead. Really excited great. We sing over, xintaizi separation of thunderous applause, and we rank of neat team, beaming Zouxia Tai to go.
Singing contest was over, we returned to the classroom teacher to us and said: "Today when we sing the good and have done quite well." Listening to the teacher, we strained the hearts of breath a sigh of relief. "Ring ring ring!" School bell rang, and we happily went home.
【译文】记一次歌唱比赛 国庆节前几天老师在班会上对我们说：“学校要举行歌唱比赛,我们班参赛的歌曲是‘让我们荡起桨’,大家回去要多唱多练,争取取个好名次.”听了老师的话,有空我们就赶紧练习这首歌,直到把它唱的滚瓜烂熟.比赛这天终于来到了.中午吃过午饭,我背着书包兴冲冲往学校赶去,刚进校门就看见校园里已经坐着好多同学了,于是我赶紧跑进教室,放下书包,拿起板凳就跟着同学们一起往校园里跑去,找到我们班所在的位置,规规矩矩坐好.比赛开始了,首先上场的是二三班,他们唱的是“北京欢迎你”“北京欢迎你,太阳下分享呼吸,黄土地上,刷新成绩————有梦想就会有奇迹.”听着这振奋人心,熟悉的歌唱,我想起了前些日子在我们国家举办的奥运会,想起运动员在赛场上拼搏的场面,想起五星红旗下,冠军们骄傲的笑脸——.歌唱完了,我和大家一起使劲拍着手,为他们喝彩,也为我们国家喝彩.比赛进行的很快,很快就轮到我们班上场.我们一个个穿着整洁的校服,带着鲜艳的红领巾,排着整齐的队伍,昂着头,雄赳赳上场了.音乐响起来,我们大声唱着.“让我们荡起双桨,小船儿推开波浪——”歌声悠扬动听,震耳欲聋的歌声里我觉得我们像到了无边无际的海面上,同学们一个个驾着小船奋力往前冲.真是激动极了.我们歌唱完了,台子下响起了雷鸣般的掌声,我们排着整齐队伍,笑容满面的走下台去.歌唱比赛结束后,我们回到教室里,老师来对我们说：“大家今天唱的真好,成绩不错.”听了老师的话,我们紧绷着的心喘了一口气.“铃铃铃!”放学铃响了,我们高高兴兴的回家了.

在我们的生活里,会遇上许许多多的黑暗,不过在黑暗里总会有一丝光明.一旦心有障碍,就是洒满一地阳光,你往往也会感到黑暗；你心中盛满阳光,就是在黑暗中也能感到希望.
　　我记得在小学的时候我的作文很不好,我也读过很多作文书,我每次写出来的作文都很枯燥无味,其实我也想写好作文,但是我就是不知该如何去写,为此,我很着急,而且,老师也不止一次找过我,说我的作文不好,要多看课外书,多积累知识,那样写作水平才会提高.可是,越想写好就越着急,作文水平就越上不去.我曾经不止一次对我说：也许我根本就不是写作文的料.直到有一次,我们班举行一次作文比赛,老师先让我们做一个游戏,然后以这个游戏为主题让我们写一篇作文,结果全班有很多同学写的都不好,我也是其中一个,老师为此很恼火,便要求我们重新写一次,我这次写的很认真,把游戏的前后经过写的栩栩如生 ,当老师公布第一名竟然是我时,我感到很惊讶,全班同学也以异样的眼光看着我.由此我得出：不管遇到什么事情,只要我们认真去对待,都会有好的结果,正如一分耕耘,一分收获.
　　我还记得在我学骑自行车的时候,没有任何人来教我,所以每次我都是神采奕奕地出去,一脸烦恼得回来,过程是艰辛的,但结果都是一样的：没学会.不过,我始终都没有放弃学习骑自行车,因为我心中始终充满了希望,坚信总有雨过天晴的时候.每当看到别人骑自行车的时候,我都忍不住去羡慕,但同时也会告诫我自己：我一定要学会.终于,我学会了骑自行车.通过这件事,我明白了：不管遇到什么困难,我们只要努力、积极的去面对就没有克服不了的,学习也同样如此.
　　在黑暗中,抓住了一缕阳光就等于抓住一丝希望,不过：无论是选择阳光还是选择黑暗都取决于我们对待困难是坚持不懈还是灰心丧气.我坚信：只要不怕困难,心中就会充满阳光.

表现军情紧急,行军神速的语句是:(1)旦辞爷娘去,暮至黄河边.不闻爷娘唤女声,但闻黄河流水鸣溅溅.但辞黄河去,暮宿黑山头.不闻爷娘唤女声,但闻燕山胡骑鸣啾啾.(2) 万里赴戎机,关山度若飞.(1)是具体描写,(2)是概括,看空的大小和具体要求了.
用素描手法,寥寥几笔勾勒出一幅边塞奇伟夜景的语句是:朔气传金析,寒光照铁衣.

I am very excited for this football match

用刻板印刷书籍,唐朝人还没有大规模采用它.五代时才开始印刷五经,以后的各种图书都是雕板印刷本.庆历年间,有位平民毕升,又创造了活板.它的方法是用胶泥刻成字,字薄得像铜钱的边缘,每个字制成一个字模,用火来烧使它坚硬.先设置一块铁板,它的上面用松脂、蜡混合纸灰这一灰东西覆盖它.想要印刷,就拿一个铁框子放在铁板上,然后密密地排列字模,排满一铁框就作为一板,拿着它靠近火烤它；药物稍微熔化,就拿一块平板按压它的表面,那么所有排在板上的字模就平展得像磨刀石一样.如果只印刷三两本,不能算是简便；如果印刷几十乃至成百上千本,就特别快.印刷时通常制作两块铁板,一块板正在印刷,另一块板已经另外排上字模,这一块板印刷刚刚印完,那第二板已经准备好了,两块交替使用,极短的时间就可以完成.每一个字都有几个字模,像“之”、“也”等字,每个字有二十多个字模,用来防备一块板里面有重复出现的字.不用时,就用纸条做的标签分类标出它们,每一个韵部制作一个标签,用木格储存它们.有生僻字平时没有准备的,马上把它刻出来,用草火烧烤,很快可以制成.不拿木头制作活字模的原因,是木头的纹理有的疏松有的细密,沾了水就高低不平,加上同药物互相粘连,不能取下来；不如用胶泥烧制字模,使用完毕再用火烤,使药物熔化,用手擦试它,那些字模就自行脱落,一点也不会被药物弄脏.毕升死后,他的字模被我的堂兄弟和侄子们得到了,到现在还珍藏着.

Cyber language is very popular now,somebody like it,because it is brief and easy to understand.somebody think that it is inconvenient to communicate.In my opinion,cyber lanuage is very useful in the modern world,the reasons are showing as follow:
Firstly,cyber language is a new language,it is novel to everyone.Everybody like new things,so they have curious about the language's development,and at the same time,they use it for communication,cause it is easy to understand.
Secondly,cyber language can produce new words or vocabularies,cause it it popular on the web,and most people go to web everyday,so it will be usefully fast.some words will be very common for the daily use.
In a word,cyber language will be very useful in the futrue.

1、20
周长=面积 2πr=πr^2 所以r=2 d=4 r^2+d^2=4+16=20
2、41
(11*12-7*13)/(13-12)=41元 因为两种卖法的总价格一样,而进货价不变；第一种卖的个数比第二种多1个,说明除去12个的进货价之后的价格,两种卖法也是一样的,也就是：13个7元利润加一个进货价=12个11元利润
3、50%
利润率=(售价-进货价)/进货价,且与商品进货价无关,不妨设为1元
所以[1*(1+20%)-1*(1-20%)]/[1*(1-20%)]=0.4/0.8=50%
4、1100
大圆半径为R,小圆半径为r,又由周长关系：2πR*90%=2πr 0.9R=r
大圆面积：小圆面积=R^2：r^2
总面积为1991平方厘米,所以大圆面积=1991*（R^2/(R^2+r^2)）=1991*1/1.81=1100
5、0.9999
0.9999×0.6+0.1111×3.6=0.1111*9*0.6+0.1111*3.6
=0.1111*（5.4+3.6）
=0.9999
6、245
27/3=9,所以三个连续自然数为8 9 10
8^2+9^2+10^2=245
7、1*（2-3-4+5）=1 5*5/5+5/5=6
8、67
147+123+132=402 这402中包含2个甲,2个乙,2个丙
402/2=甲+乙+丙
所以平均值为：201/3=67
9、17 22
规律为+5 -7 +5 -7
10、2216.445
1995+199.5+19.95+1.995=1995*（1+0.1+0.01+0.001）
=1995*1.111
=(2000-5)*1.111
=2222-5.555=2216.445
11、加入30%的盐水30千克
设加入X千克
(20*10%+30%)*X/(20+X)=22%
解方程得到X=30
12、
甲14/3升,乙7/3升
设甲X升,则乙7-X升
配好后的溶液水=酒精,即6X+9(7-X)=9X+3(7-X)
解得X=14/3 7-X=7/3
13、“这样所得利润就只有原计划的31”,是3分之一么?

1.a^2-1/2a+1/16=（a-1/4）^2
2.x^2-3x+1/2x^2-4=0 3/2x^2-3x-4=0 x^2-2x-8/3=0 （x-1）^2-11/3=0 x-1=±√11/3 x=±√11/3+1
2a^3b^2（a-b）/a+b===-2a^3b^2
-0.0201×10^(-5):指该数的倒数,也就是-1000/201×10^5.

极其---锅盖

篮球是美国和世界其他地区最受欢迎的运动之一。它已有100多年的历史。篮球的发明者詹姆斯.奈史密斯是加拿大人。他在1891年为他的学生们发明了篮球。起初，它只是一项室内运动，学生们在坏天气里也能打篮球。

(a+b-c)(-a-b+c)怎么解...求神速!要完全平方公式解,
=-(a+b-c)(a+b-c)
=-(a+b-c)²
=-(a²+b²+c²+2ab-2ac-2bc)
=-a²-b²-c²-2ab+2ac+2bc;
