我万能的百度【酉农】这个字怎么念?意义是什么?

万能凤头
●青春是用意志的血滴和拼搏的汗水酿成的琼浆——历久弥香；青春是用不凋的希望和不灭的向往编织的彩虹——绚丽辉煌；青春是用永恒的执著和顽强的韧劲筑起的一道铜墙铁壁——固若金汤.
●信念是巍巍大厦的栋梁,没有它,就只是一堆散乱的砖瓦；信念是滔滔大江的河床,没有它,就只有一片泛滥的波浪；信念是熊熊烈火的引星,没有它,就只有一把冰冷的柴把；信念是远洋巨轮的主机,没有它,就只剩下瘫痪的巨架.
●站在历史的海岸漫溯那一道道历史沟渠：楚大夫沉吟泽畔,九死不悔；魏武帝扬鞭东指,壮心不已；陶渊明悠然南山,饮酒采菊……他们选择了永恒,纵然谄媚诬蔑视听,也不随其流扬其波,这是执著的选择；纵然马革裹尸,魂归狼烟,只是豪壮的选择；纵然一身清苦,终日难饱,也愿怡然自乐,躬耕陇亩,这是高雅的选择.在一番选择中,帝王将相成其盖世伟业,贤士迁客成其千古文章.
●只有启程,才会到达理想和目的地,只有拼搏,才会获得辉煌的成功,只有播种,才会有收获.只有追求,才会品味堂堂正正的人.
●如果说友谊是一颗常青树,那么,浇灌它的必定是出自心田的清泉；如果说友谊是一朵开不败的鲜花,那么,照耀它的必定是从心中升起的太阳.
多少笑声都是友谊唤起的,多少眼泪都是友谊揩干的.友谊的港湾温情脉脉,友谊的清风灌满征帆.友谊不是感情的投资,它不需要股息和分红.（友谊可以换其他词语）
●盈盈月光,我掬一杯最清的；落落余辉,我拥一缕最暖的；灼灼红叶,我拾一片最热的；萋萋芳草,我摘一束最灿的；漫漫人生,我要采撷世间最重的———毅力.
●如果说生命是一座庄严的城堡,如果说生命是一株苍茂的大树,如果说生命是一只飞翔的海鸟.那么,信念就是那穹顶的梁柱,就是那深扎的树根,就是那扇动的翅膀.没有信念,生命的动力便荡然无存；没有信念,生命的美丽便杳然西去.（划线处可以换其他词语）
●毅力,是千里大堤一沙一石的凝聚,一点点地累积,才有前不见头后不见尾的壮丽；毅力,是春蚕吐丝一缕一缕的环绕,一丝丝地坚持,才有破茧而出重见光明的辉煌；毅力,是远航的船的帆,有了帆,船才可以到达成功的彼岸.
●爱心是一片照射在冬日的阳光,使贫病交迫的人感到人间的温暖；爱心是一泓出现在沙漠里的泉水,使濒临绝境的人重新看到生活的希望；爱心是一首飘荡在夜空的歌谣,使孤苦无依的人获得心灵的慰藉.
●心的本色该是如此.成,如朗月照花,深潭微澜,不论顺逆,不论成败的超然,是扬鞭策马,登高临远的驿站；败,仍滴水穿石,汇流入海,有穷且益坚,不坠青云的傲岸,有“将相本无主,男儿当自强”的倔强.荣,江山依旧,风采犹然,恰沧海巫山,熟视岁月如流,浮华万千,不屑过眼烟云；辱,胯下韩信,雪底苍松,宛若羽化之仙,知退一步,海阔天空,不肯因噎废食.
●快乐=物质/欲望.这是美国经济学家萨缪尔森提出的快乐方程式.从经济学的观点看,物质消费越大,欲望越小,快乐就越大,正应了中国人的一句古话“知足常乐”.反之,如果一个人的物质消费有限,而欲望无穷大,将会怎样呢?路瓦栽夫人有那么多“梦想”,又有那么多“陶醉”,她怎么能不痛苦、伤心呢?
●俄国作家契诃夫说：“有大狗,有小狗,小狗不该因为大狗的存在而心慌意乱.所有的狗都应该叫,就让他各自用上帝给他的声音.
●成熟是一种明亮而不刺眼的光辉,一种圆润而不腻耳的音响,一种不需要对别人察颜观色的从容,一种终于停止了向周围申诉求告的大气,一种不理会哄闹的微笑,一种洗刷了偏激的淡漠,一种无须声张的厚实,
一种并不陡峭的高度.
●爱,有的时候不需要山盟海誓的承诺,但她一定需要细致入微的关怀与问候；爱,有的时候不需要梁祝化蝶的悲壮,但她一定需要心有灵犀的默契与投合；爱,有的时候不需要雄飞雌从的追随,但她一定需要相濡以沫的支持与理解.
●微笑着,去唱生活的歌谣,不要埋怨生活给予了太多的磨难,不必抱怨生命中有太多的曲折.大海如果失去了巨浪的翻滚,就会失去雄浑；沙漠如果失去了飞沙的狂舞,就会失去壮观.人生如果仅去求得两点一线的一帆风顺,生命也就失去了存在的意义.
●即使青春是一枝娇艳的花,但我明白,一枝独放永远不是春天,春天该是万紫千红的世界.
即使青春是一株大地伟岸的树,但我明白,一株独秀永远不是挺拔,成行成排的林木,才是遮风挡沙的绿色长城.即使青春是一叶大海孤高的帆,但我明白,一叶孤帆很难远航,千帆竞发才是大海的壮观.
●生命不是一篇"文摘",不接受平淡,只收藏精彩.她是一个完整的过程,是一个"连载",无论成功还是失败,她都不会在你背后留有空白；生命也不是一次彩排,走得不好还可以从头再来,她绝不给你第二次机会,走过去就无法回头.
●试试看——不是像企鹅那样静静的站在海边,翘首企盼机会的来临,而是如苍鹰一般不停的翻飞盘旋,执著的寻求.
试试看——不是面对峰回路转、杂草丛生的前途枉自嗟叹,而是披荆斩棘,举步探索.
试试看——不是拘泥于命运的禁锢,听凭命运的摆布,而是奋力敲击其神秘的门扉,使之洞开一个新的天地.微笑着,去唱生活的歌谣.
●能够破碎的人,必定真正活过.林黛玉的破碎,在于她有刻骨铭心的爱情；三毛的破碎,源于她历经沧桑后一刹那的明彻与超脱；凡高的破碎,是太阳用黄金的刀子让他在光明中不断剧痛,贝多芬的破碎,则是灵性至极的黑白键撞击生命的悲壮乐章.如果说那些平凡者的破碎泄漏的是人性最纯最美的光点,那么这些优秀的灵魂的破碎则如银色的梨花开满了我们头顶的天空.
●春蚕死去了,但留下了华贵丝绸；蝴蝶死去了,但留下了漂亮的衣裳；画眉飞去了,但留下了美妙的歌声；花朵凋谢了,但留下了缕缕幽香；蜡烛燃尽了,但留下一片光明；雷雨过去了,但留下了七彩霓虹.
●《太阳每天都不辞劳苦地升起》巴尔扎克说过“不幸,是天才的进升阶梯,信徒的洗礼之水,弱者的无底深渊”.风雨过后,眼前会是鸥翔鱼游的天水一色；走出荆棘,前面就是铺满鲜花的康庄大道；登上山顶,脚下便是积翠如云的空蒙山色.
在这个世界上,一星陨落,黯淡不了星空灿烂,一花凋零,荒芜不了整个春天.
人生要尽全力度过每一关,不管遇到什么困难不可轻言放弃.
●宽容,是一种坦荡,可以无私无畏,无拘无束,无尘无染.
宽容,是一种豁达,是比海洋和天空更为博大的胸襟,是宽广和宽厚的叠加,延续和升华.宽容有度,宽容无价,宽以待人,这是人生处世的基本法则

开头：风凛冽地划过肩膀,带起一丝荒凉,掠过湖面,燕子的尾巴轻扫你的心灵.
结尾：轻轻的,温暖的风抚过你的脸庞,带来了温柔,带走了悲伤

I hoep everything goes well

应该不能 确实利用耦合反应可以使不能自发的反应能够反应,比如TiO2 + 2Cl2 + 2C===TiCl4 + 2CO 但这不能表明该反应自发进行,还需要很高的条件,高温等等

解题思路：在NaBH₄+2H₂O=NaBO₂+4H₂↑反应中，NaBH₄中H元素的化合价为-1价，H₂O中H元素的化合价为+1价，二者发生氧化还原反应，其中NaBH₄是还原剂，H₂O是氧化剂．

在NaBH₄+2H₂O=NaBO₂+4H₂↑反应中，NaBH₄中H元素的化合价为-1价，H₂O中H元素的化合价为+1价，二者发生氧化还原反应，其中NaBH₄是还原剂，H₂O是氧化剂，氢气既是氧化产物又是还原产物，
反应中B元素的化合价没有发生变化，反应中氧化剂和还原剂中化合价变化的数值相等，则被氧化的元素与被还原的元素质量比为1：1，故选D．

点评：
本题考点： 氧化还原反应．

考点点评： 本题考查氧化还原反应，题目难度不大，本题注意反应中各元素的变化，根据化合价的变化计算电子转移的数目．

一、开头万能公式
1.开头万能公式一：
名人名言：有人问了，“我没有记住名言，怎么办？尤其是英语名言？”很好办：编！原理：我们看到的东西很多都是创造出来的，包括我们欣赏的文章也是，所以尽管编，但是一定要听起来很有道理，而且没准将来我们就是名人呢！对吧？
经典句型：A proverb says, “ You are only young once.” (适用于已记住的名言)It goes without saying that we cannot be young forever. (适用于自编名言)更多经典句型：As everyone knows, No one can deny that…
2.开头万能公式二：
数字统计原理：要想更有说服力，就应该用实际的数字来说明。原则上在议论文当中不应该出现虚假数字的，可是在考试的时候哪管那三七二十一，但编无妨，只要我有东西写就万事大吉了。所以不妨试用下面的句型：According to a recent survey, about 78.9% of the college students wanted to further their study after their graduation.
看起来这个数字文绉绉的，其实都是编造出来的，下面随便几个题目我们都可以这样编造：
Honesty
根据最近的一项统计调查显示，大学生向老师请假的理由当中78%都是假的。
Travel by Bike
根据最近的一项统计调查显示，85%的人在近距离旅行的时候首选的交通工具是自行车。
Youth
根据最近的一项统计调查显示，在某个大学，学生的课余时间的70%都是在休闲娱乐。
Five-day Work Week Better than Six-day Work?
根据最近的一项统计调查显示，98%的人同意每周五天工作日。
更多句型：A recent statistics shows that …
二、结尾万能公式
1.结尾万能公式一：如此结论
说完了，毕竟要归纳一番，相信各位都有这样的经历，领导长篇大论，到最后终于冒出个“总而言之”之类的话，我们马上停止开小差，等待领导说结束语。也就是说，开头很好，也必然要有一个精彩的结尾，让读者眼前一亮，这样，你就可以拿高分了！比如下面的例子：
Obviously(此为过渡短语), we can draw the conclusion that good manners arise from politeness and respect for others.
如果读者很难“显而见之”，但说无妨，就当读者的眼光太浅罢了！
更多过渡短语：
to sum up, in conclusion, in brief, on account of this, thus
更多句型：
Thus, it can be concluded that…, Therefore, we can find that…
2.结尾万能公式二：如此建议
如果说“如此结论”是结尾最没用的废话，那么“如此建议”应该是最有价值的废话了，因为这里虽然也是废话，但是却用了一个很经典的虚拟语气的句型。拽！
Obviously, it is high time that we took some measures to solve the problem.
这里的虚拟语气用得很经典，因为考官本来经常考这个句型，而如果我们自己写出来，你说考官会怎么想呢？更多句型：
Accordingly, I recommend that some measures be taken.
Consequently, to solve the problem, some measures should be taken.

留一份——给自己

这些是一般短语，要遇到合适话题才能写……我记了很多，又忘了很多……从做题中积累记忆即可………很明显，大战在即，我已没机会，所以我才想记些应急短语，拿多几分。。。感谢你的细致回答，我的问题已经解决了，多谢大家的帮助哦！啊，没关系，我也是今年的考生，而且还是复读加油吧！！！...

最好去看点真题,我也是,和你一个时候考

Looking forward to your reply 盼望收到你的来信 As a coin has two sides，（后接总结）事物都有两面性 In a word,一句话概括来说 （后接总结 Moreover 还有 就想到这些常用的←_←

人的血型分A、B、AB、O四型~
其中A型血含有A抗原~B抗体~
B型血中含有B抗原~A抗体~
AB型血中含有A抗原和B抗原~但是没有A抗体~也没有B抗体~
O型血没有A抗原、B抗原,但是含有A抗体和B抗体~
之所以O型血可以称为“万能输血者”是由于临床上交叉配血的原则而决定的：
交叉配血的实验分两步：
1.主试验：是用受血者的血清和供血者的红细胞反应,如果受血者的血清中含有能够与供血者红细胞发生发应的抗体,就会发生凝集发应,就是绝对不可以进行输血的.
O型血的人作为供血者,他的血中没有任何红细胞抗原（既没有抗A,也没有抗B）,所以,无论接受血液的人的红细胞有什么抗原也无法与之发生反应,所以不会有凝集的发生.
2.副试验：受血者的红细胞与供血者的血清反应.O型血如果供血给A、B、AB型的人,都会发生反应,产生凝集,但是相0对要求不是很严格.但是如果条件允许,还是要坚持同型输血!而且还要要求供血者血中含有的A、B抗体不能太高（要小于1：64）

这得根据实际情况来定,如果存放时间较短,环境又不恶劣,可以不用再做防锈处理.但如果是要长期防锈或是时间较长,就需要再做防锈处理,可以选择采用专业的防锈油,或是配合气相防锈包装材料使用.

友谊是一次奇妙的实验,能证明万变不离其中的现象

因为tg(X)函数不能取x=Kπ+（π/2）的值.当x=Kπ+（π/2）时,tg(X)趋向无穷.

令u = tan(x/2)
则dx = 2 du/(1 + u²)
sinx = 2u/(1 + u²)
cosx = (1 - u²)/(1 + u²)
tanx = 2u/(1 - u²)

设Cu3P前系数为1,P4前系数为x
所以有 xP4+CuSO4+H2O----1Cu3P+H3PO4+H2SO4
由同铜原子守恒,得CuSO4前系数为3,即 xP4+3CuSO4+H2O----1Cu3P+H3PO4+H2SO4
由硫原子守恒,得H2SO4前系数为3,即 xP4+3CuSO4+H2O----1Cu3P+H3PO4+3H2SO4
由磷原子守恒,得H3PO4前系数 = 4x-1,即 xP4+3CuSO4+H2O----1Cu3P+(4x-1)H3PO4+3H2SO4
由氢原子守恒,得H2O前系数 = 6x+1.5,即xP4+3CuSO4+(6x+1.5)H2O----1Cu3P+(4x-1)H3PO4+3H2SO4
由氧原子守恒,得：12 + 6x+1.5 = 4(4x-1) + 12
解得x = 0.55
所以 0.55P4+3CuSO4+4.8H2O==1Cu3P+1.2H3PO4+3H2SO4
化为整数,即 11P4+60CuSO4+96H2O==20Cu3P+24H3PO4+60H2SO4

错误
没有万能催化剂
温度升高,反应速率升高,但不能说热可以催化某一反应
催化是指降低反应活化能以达到加快反应速度的目的
而反应活化能是与温度无关的
何况存在很多低温反应,也就是说如果升高温度这些反应将无法进行,怎么能说热可以催化任何反应?

u=tanx/2
sinx=2u/(1+u^2)
cosx=(1-u^2)/(1+u^2)
tanx=2u/(1-u^2)

什么三角函数转化多项式?是有理式才对把?
tan(x/2)=u
sinx=2u/(1+u^2)

tanx=2u/(1-u^2)
dx=2/(1+u^2)du
应该是这个吧?

CxHy + （x+y/4）O2 == xCO2 + y/2H2O
左边x个C,右边就是x个CO2,左边y个H,右边就是y/2个H2O,最后根据O守恒,可知O2系数为（x+y/4）
后一个好像有问题吧,O2为什么是Oz呢?是不是CxHyOz + O2反应呢?
CxHyOz + （x+y/4-z/2）O2 == xCO2 + y/2H2O
配平类似,O2系数计算的时候,右边的O的总数减去有机化合物中的z个O就行了.
