20 years said long but short, in life, the most valuable best time of the most far away in these twenty years. Happy people always understand the aftertaste,happiness is often found her beauty in experience can. I remember as a childlikes to grow up, to think that you can do a lot of things, then my dream is not a luxury car, rich life, ever thought of ever had it, accompanied by parents, havefriends, life is sufficient; gradually grew up, I was curious about everything,remember the primary school first contact with the computer, then don't know how to use it, even the mouse can not get good. In the past six years, at the sight of the heavy computer somewhat ridiculous, recalled that when theembarrassed like still fresh in my memory. Indeed, over the years, childhoodstory stopped, the reality of the pressure further increased, that is we can neverin childhood could consider. Now sixteen and seven, I also want to give at the age of seven or eight, I say, if like a child that my life is too short, it is not the end. Life continues, the future I may face greater challenges, but I want to "do not abandon, do not give up" at that time, success is not far away waiting for you!

1.蜘蛛记
今天,我独自躺在床上,眼睛半张半合,无意间,我看到墙壁上有一个黑乎乎的东西,我想：这会不会是一只蜘蛛啊!我怀着好奇心,便站起身,走上前去,想看个究竟,没想到,它竟然动了起来.啊!它真的是“八脚怪”!我吓得“哇”地一声叫了出来,要知道,我最怕的虫子就是蜘蛛了,何况这只蜘蛛又黑又大,怪吓人的.
妈妈听到叫声,便走过来问：“什么事啊?”我结结巴巴地说：“这儿有…蜘…蛛.”说完,便指了指墙壁上的蜘蛛,谁知,妈妈却若无其事地说：“我还以为什么事呢,大惊小怪的,不就是一只蜘蛛吗,它又不会咬人,你怕什么呀?”说完便走了出去.我想：一只小小的蜘蛛怕什么呀,我比它大好几百倍呢!用一根手指头就能把它压成肉饼.想是这么想,可我的眼睛却始终盯着那个“八脚怪“,怕它爬到我的小床上来.只见它爬呀爬,当它爬到空调的边上时,忽然掉了下来,我心里“咯噔”一下,目不转睛地盯着蜘蛛,没想到它荡在了半空中,原来蜘蛛用它吐出的丝在做杂技表演呢,等它玩够了,又像弹簧 一样“嗖”的一下上去了,我长长地吁了口气,幸亏没掉到我的床上来,唉,真是有惊无险啊!
我正在为自己庆幸,没想到它以飞快的速度爬向我的小床,我吃了一惊,刚才那股高兴劲儿早就烟消云散了,随之而来的是“咚咚”的心跳声,可这只蜘蛛却一点儿也不知情,还在往我的小床的方向爬过来.我忙跳下床,去搬我的“救兵”—爷爷,爷爷看到这个情景,便撕了一张报纸,他把报纸放在蜘蛛的必经之路,等它“自投罗网”,只见蜘蛛真的沿着报纸爬了上来,爷爷轻轻地拿起报纸,打开窗户,把蜘蛛放回了大自然.
我问爷爷：“爷爷,您为什么不把蜘蛛打死啊?”爷爷笑着对我说：“蜘蛛专吃蚊子,是益虫,我们应该保护它才对呀.”我听了,点了点头,心想：看一样东西不能只看它的外表,只有懂得了更多的文化知识,才能够更好的保护和利用它们.
2.第一次当保姆
在我成长的路上,每天都发生许许多多的事,它们就像天上的星星,在我的心里闪闪发亮.今天,一颗闪亮的星星又在我的脑际里划过.求知时空
这天早上,我来到外婆家渡假,但姨妈却把她那两岁半的儿子小健送到外婆家,让外婆看管.正巧,外婆有事在身,便把小健交给我.外婆临走时吩咐我说：“当好小保姆,看好小孩.” 不就是逗逗小孩吗?容易,我便一口答应了.
谁知,出乎我的意料,当小保姆并不容易.外婆一走,麻烦事像海浪一样不断地向我涌来.你看这小家伙,把玩具弄得乱七八糟,东一堆,西一件,还没玩够五分钟,又要吃东西.真拿他没办法!我只好在屋子里忙得团团转.最糟糕的是他又撒尿了,满地都是表弟的杰作——“童子尿”,这下我又忙开了,换裤子,拖地……要不是看他是姨妈的宝贝儿子,我不狠狠地打他一顿才怪呢.
“要当好小保姆.”外婆的话在我的耳边不断回响.怎样才能当个好的小保姆?逗?吓?都不行.得想个新办法来完成外婆交给我的任务,我暗暗下定了决心.
我又尝试了几种方法来逗小宝贝,结果还是以失败告终,几乎弄得我筋疲力尽.我急得满头大汗,怎么办呢?我带着求救般的目光扫视一下周围,希望得到一点提示.忽然,我的目光落在大厅的VCD上,我灵机一动,立刻有了主意.对,就这么办!我插上电源,打开VCD的开关,放上歌碟,一优美动听的歌声从音箱传出来.咦,奇迹出现了,表弟像被音乐的魅力吸引住了,情不自禁地跟着音乐手舞足蹈起来.你看,他扭扭小屁股,拍着小手,奶声奶气地和着音乐哼着歌,乐得眉眼开了花.看着表弟那副自得其乐的模样,我不禁大笑起来.时间,像流水般很快过去了.不大一会儿,外婆外出回来了,看见小表弟安然无恙,啧啧称赞我这个小保姆有办法……求知时空
“经一事,长一智,” 通过这件事,使我懂得了一个人无论做什么事,只要冷静沉思一下,认真想办法,就可以做好.
3.第一次走夜路
我们的生活中,有过许许多多的第一次,一个个第一次就像一个个脚印,印在我们成长的道路上,其中,我第一次走夜路的情景最令我难忘,并且时时萦绕于心.
那是三年前的事情了,那时候,我住在外婆家,一天晚上,表哥给了我一元钱,让我去买两根雪条,并关心地问我：“你能行吗?”我拍了拍胸膛,说：“凭我这贼大的胆儿,肯定能行!”说着,我便走出家门,刚才那股得意劲儿一下子跑到九宵云外去了,但是,为了“捍卫”我的面子,我只好硬着头皮往前走,因为道路两旁都是高大笔直的白杨树,所以风一吹来便“沙沙”做响,我害怕得东张西望,万般无奈之下,只好唱丁丁的歌曲来壮壮胆：“东汉末年分三国,峰火连战不休……”一路上,我便一直这样引吭高歌,当我快来到小卖部时,一阵脚步声钻进了我的耳朵,我吓得脸色煞白,两腿发软,哆哆嗦嗦地回头一看,有个走路踉踉跄跄的酒鬼正往我这边走来,我心想：酒鬼也是鬼呀!想着想着,不由得大吃一惊,大喊一声：“溜!”我便以龙卷风般的速度飞奔到小卖部,真是虚惊一场!
买完了雪条后,我一路狂奔,路过坟地时,突然响起了一阵鬼哭狼嚎的声音,我来了个“急刹车”,只听见有人喊：“拿雪条来!”我早已吓得脸色铁青,现在更是雪上加霜,我心想：害怕也不是个办法,看来只有以毒攻毒啦!我学着包公审问犯人的样子,大喝一声：“来者何人,速速报上名来!”这时,一个黑影从坟地上窜了出来,我吓得往后倒退了几步,定神一看,原来是表哥,我马上分给表哥一根雪条,我们俩人便吃着雪条走回家去.
通过这件事,我明白了一个道理：世界上并没有鬼,只不过是人吓人而已.

2.用机械能守恒来计算整个过程机械能守恒,所以机械能E=mgh0+1/2mv0^2=150J当重力势能等于动能时,重力势能就是机械能的一半Ep=1/2E=75J又Ep=mgh1所以h1=7.5m

为生命的尊严喝彩
当11岁的北川女孩李月,在轮椅上缓缓给右脚穿上红舞鞋,开始跳那“永不停跳的舞步”,很多人禁不住潸然泪下.
残酷的命运让一个酷爱芭蕾的女孩失去了左腿,但她选择了坚强,选择了在全世界面前重新起舞.
坐在轮椅上的侯斌,抓住那条长长的绳索,努力向上攀升,点燃北京2008年残奥会的主火炬,这一幕同样感动了世界.
健全人或许很难真切体会到,失去一条腿、失去从此站起来的能力,对当时只是一个9岁的孩子到底是一种什么样的打击,但我们看到他终于从残疾少年成长为残奥冠军,并在点燃主火炬的过程中向全世界展现了动人风采.
人生有坦途,也有坎坷.春风得意或许引人艳羡,但生命的硬度与尊严却往往体现在人生遭遇挫折的当口.李月、侯斌们直面命运的残酷挑战,在努力抗争中重新获得人生飞翔的翅膀.他们奋发向上、自强不息的强者姿态,带给我们的不仅有感动,更有深深的启迪：灾难可以摧残肢体,但摧不毁生命的意志、尊严；挫折或许可以让人一时失意,但却永远无法阻挡坚定的追梦者奋勇向前的脚步.
北京2008年残奥会开幕式让我们记住了李月、侯斌等原本并不熟悉的名字,而我们更该记住的还有他们在人生逆境中所展现出的顽强不屈和永不放弃.
记住李月、侯斌,记住这些名字背后的感人故事,我们会真切地理解“超越、融合、共享”的丰富内涵,我们更会从中收获坚韧不拔、携手共进的精神动力.

　所谓读一本好书就是交一个良师益友,但我认为读一本好书就是一次大冒险,大探究.一次体会书的过程,真的很有意思,咯咯的笑声,总是从书香里散发；沉思的目光也总是从书本里透露.是书给了我启示,是书填补了我无聊的夜空...

1mmol/L表示每升血液中含有1毫摩尔（mmol）的葡萄糖.葡萄糖的相对分子质量为180,就表示1摩尔（mol）的葡萄糖的质量为180克（g）,即1mmol的质量为180毫克（mg）.这样,1mmol/L的血液中每升就含有葡萄糖180mg.1/10升（1dL）这样的血液中就含有葡萄糖18mg.这就是说1mmol/L就相当于18mg/dL.
某人检测结果为92mg/dL,那么将其表示为mmol/L,只要数值上除以18的换算系数就可以了.

石灰水增重是因为通入了CO2和H2O,
CO2+Ca(OH)2=CaCO3+H2O
44 100
xg 20g
x=8.8g
n(CO2) = 0.2 mol
可以看出相当于1个CO2带出一个CaO（CaCO3看成CaO和CO2）,也就是说1 mol CO2通入,带出1 mol CaO,也就是带出56 g质量,根据碳酸钙也就是沉淀是20 g,可以得出CO2是0.2 mol,所以带出的CaO质量为58*0.2=11.6g,而实际减少5.8g,说明生成的水质量为11.6-5.8=5.4g
C：H个数比 = 0.2 / (5.4/18*2) = 1/3
即碳氢个数比为1：3,
A C2H4,B CH2OHCH2OH,C C2H5OH,D HCOOCH3
所以选择BC

写好一篇议论,首先是观点要鲜明,论据要充分,再者是论证要有力.重要的还是平时的积累,要多看一些好的作品.平时多看书以积累一些素材作为论据,还要多加练笔.这是我个人看法,说得不好的还请见谅!
我认为应有一本个人论点论据辑,将好的事例名言记载其中,还要多看些历史书,作为事实论据的来源.
建议在论据方面,除了要运用典故外,还可以平时多关注现实生活的事实事例恰当运用于其中,有助于拓宽论据的古今广度,也有助于使文章能贴近现实生活,还能体现所运用的论据的新颖性,避免使用陈词滥调,削弱文章的说服力.
说起来容易做起来难,我认为还是要多看书,而且看的书的范围要广,尽量涉及生活的各个方面,这样就为你的写作打下了好的基础,才能写出好的作品.
要先分好中心论点和分论点,然后围绕主题论证论点,论据要真实易懂.

look 是一个系动词,意思是“看起来.”.用法和“be动词”差不多,后面接形容词.比如：You look(也可是are) beautiful.

地理实体空间位置、分布、形态、空间关系（距离、方位、拓扑、相关场）等基本特征的精确描述依赖于空间参考系统.
空间参考系统定义了地理空间三维表面的空间坐标系统及各坐标系统间的数学关系.所有的地理要素只有按经纬度或者特有的空间坐标系统进行严格的空间定位,才能使具有时序性、多维性、区域性特征的空间要素进行复合和分解,将其中隐含的信息变为显示表达,形成空间和时间上连续分布的综合信息基础,支持空间问题的分析、处理与决策.
可见,地理空间参考系统是对地理空间的精准表达并成为数字模拟的基础.
对于楼主的问题补充,我可以如此解释：空间参考系统就是在空间上建立空间直角坐标系以作为空间参考系.即以解析几何的方法来处理空间几何问题,而这可以广泛用在地理上.
望楼主满意!

你的担忧是有道理的,因为人的重心位置可认为在人体中间（算重力势能时要用重心位置的）.
分析：对于目前正常的跳高比赛所采用的方式－－－背越式,那么人过杆时,可认为重心（人体中点）离地高度是h,所以重力势能此时为 mgh .
C选项对.
注：若是用跨越式,则重力势能会大于mgh（因人体中点比h高处还要高）.
在没有说明的情况下,通常要根据常见的或大多数常规的情况来分析.

踢毽子
校园里有许多奇怪的流行风,这不,最近校园里又因为天气转冷而刮起了一阵狂热的“毽子风”.
“叮铃铃’下课铃响了,女生们都拿出早已准备好的毽子,一窝蜂地涌出教室,呼朋唤友,及时占好有利地盘.有的在比赛,有的在表演,有的在教男生们踢毽子……走廊里顿时充满了欢声笑语.
在走廊的西头,有一大群人围在一起,还不是传来叫好声.那边到底在干嘛呢?我跑过去一看,原来是我班的毽子大王——袁雯洁在表演踢毽子.
只见毽子在她的脚下忽左忽右、忽上忽下地翻飞,有时在她的身前身后蹦来蹦去.她时而转向那边,时而转向这边,紧紧地跟着毽子,眼睛也始终跟着毽子转动着.踢着踢着,毽子突然出现了“险情”,毽子打到了鞋底边上,被踢出去好远.当大家都在为她感到惋惜之时,她却一个箭步冲上前,一个勾脚将毽子勾了回来,“129、130、131、132……真不愧是毽子大王!
除了袁雯洁之外,我们班还有许多高手,真可谓是“高手如云”啊!可偏偏有些男孩子不自量力,想和我们这些高手比赛,我们一个人对阵五个人,把他们打败了!
“叮铃铃”上课啦,大家都极不情愿地收起毽子回到教室内坐好,但总不忘说一句：“下课再来!”

C={1,2} 因为x=1或x=2.

可以从中先写汉字的起源历史 然后就是学习汉字感受它的魅力 以及传承

很多很多事都被自己的坏记性给遗失了.悲伤的事,快乐的事,层层叠叠地织成了我的12岁.有人说过：“越想忘掉的事就越忘不掉.”于是,我想忘掉的记住了,想记住的忘掉了,这是件多么抱歉的事.我存活在自己的感情纠缠中,无法自拔.亲情,友谊……太多太多,该消逝的消逝了.我竭力想忘记一种缠绵在我身旁的感情——友谊.但是,正如上文,我越想忘就越忘不掉,于是,我竭力地想纪念它.友谊.看见这两个字,心会颤抖,就好象快乐都被抽走,剩下的心,空空的.害怕听见这两个字,不知道为什么,只是这样的感觉陪着我过了好久好久.有很长的一段时间我总是挣脱不开某个人带给我的阴影.她给我的影响总是那样的深刻.而现在回过头去看那时的我,是多么的幼稚.怕是连我自己都会发笑.也许,我一直很迷恋过去.记得以前,我们一起做着傻傻的梦,虽然达成不了,但是总是很开心.为了这个不现实的梦,我们去报名参加了歌唱比赛.那是个暑假,我们3个人兴致勃勃地去报名,虽然知道自己没有很厚的功底,但是重在参与.到了比赛场地,我们显然紧张.看着镜头,开唱了.歌名是《花都开好了》.这是我很喜欢的歌,但是我们并非唱得很完美.而且,忽略了一个比较重要的东西——笑.点评的人说：“连花都开好了,为什么看不到你们的微笑呢?”原来,我们始终是不会笑的孩子.听完点评,我们逃也似的离开了.其实,在台上的表现还没台下的好.都是那该死的紧张,使这次我们没进海选.当然,更多的是我们唱得不好.虽然没进海选,但是那次真的很开心.即使我们高兴而来,失望而去；即使我们失败了；即使这次的打击挺大的.但是,我们依旧开心,因为可以3个人一起去参加比赛,可以把我们3个的努力展现给大家,可以把我们的友谊告诉给所有人.仅此,便足矣.可是,你说,我们分开吧.我说,好啊.你说,那以后不做朋友了.我点头.几句话,结束了曾经所爱的.刚开始的几个星期好不习惯,身边空空如也,心里空空如也.但是,迟早得振作起来.于是,我试尝着忘记.时光荏苒,昔日的伤都已抹去.忘不掉亦忘得掉,即使最后仍忘不掉.我用这篇文章来祭奠我们死去的友谊,并把它从此丢在记忆尾端,不怀念,不懊悔.我会一直向前走,以前的事只是回忆,只是过往,而她们,只是我人生的过客.即便忘不了

夏天的雨
那个夏天的晚上,天气突然变凉.我关着窗户睡到了次日清晨.
第二天清晨,从一夜酣睡中醒来,打开窗户,一股清新的带着泥土清香的气息扑面而来.新鲜的空气真是一味药,一味可以提神、润肺的良药.呀!昨夜已下过雨了.
天依然是阴阴的,似乎雨孩子们又在天上呆不住了.开始,先是一声小小的雷声,随着雷声,无数小小、小小的雨滴开始向地面俯冲.它们一个个倒也挺厉害,“进攻”没多会儿,地面就又变得湿漉漉的.但它们仍是一声不响,静静的、静静的,逐渐地“占领”着地面上的一切.
忽然,一声响雷,一道闪电,几十朵更大、更黑的云团使人忘记了方才的微微细雨,相继而来的,则是落在地面上就溅出雨花瓣的中雨.雨声大了起来,嘈嘈杂杂的,地面开始喧闹起来.街上的雨伞多起来了,红的、绿的、蓝的、花的、透明的……,宛如雨后鲜艳的蘑菇、宛如春天争艳的百花.雨声也有所不同,从淅沥、淅沥变成了哗啦啦、哗啦啦,更强时则宛如千军万马,浩瀚无垠.
渐渐的,千军万马远了,雨又细起来,细起来,像牛毛似的在变明的天空中柔柔地飘着.
最后小雨也无影踪了.哇!彩虹出现了,赤、橙、黄、绿、青、蓝、紫……像条彩带斜挂在天边.太阳也笑呵呵的,像个孩子似的.就在此时,大地上春光一片,苍翠的枝叶上挂着水珠,好象要滴下水来,连小草也显得格外清新,一片生机勃勃的景象,就仿佛这是春天,而不是夏天.
夏天的雨,真美啊!
