1+到99是多少

等于1050

1+2+。。+99=（1+999）*99/2=4950等差数列求和方法：【（首项+末项）*项数】÷2拓展资料：等差数列是常见数列的一种，可以用AP表示，如果一个数列从第二项起，每一项与它的前一项的差等于同一个常数，这个数列就叫做等差数列，而这个常数叫做等差数列的公差，公差常用字母d表示。例如：1,3,5,7,9……（2n-1)。等差数列{an}的通项公式为：an=a1+(n-1)d。前n项和公式为：Sn=n*a1+n(n-1)d/2或Sn=n(a1+an)/2。注意： 以上n均属于正整数。

1+2+3+...+99=(1+99)+(2+90)+(3+97)+......(49+51)+50=100*49+50=4950

　　1到99是一个等差数列，首项为1，末项为99，公差为1，项数为99。等差数列前项和=首项*项数+项数*（项数-1）*公差/2，所以此题=1*99+99*（99-1）*1/2=99+99*98/2=99+99*49=99+4851=4950。 　　等差数列等差数列是指从第二项起，每一项与它的前一项的差等于同一个常数的一种数列，常用A、P表示。这个常数叫做等差数列的公差，公差常用字母d表示。 　　例如：1,3,5,7,9……2n-1。通项公式为：an=a1+(n-1)*d。首项a1=1，公差d=2。前n项和公式为：Sn=a1*n+[n*(n-1)*d]/2或Sn=[n*(a1+an)]/2。注意：以上n均属于正整数。 　　加法加法（通常用加号“+”表示）是算术的四个基本操作之一，其余的是减法，乘法和除法。例如，在下面的图片中，共有三个苹果和两个苹果的组合，共计五个苹果。该观察结果等同于数学表达式“3+2=5”，即“3加2等于5”。

1、从1加到99是4950，这个题目有很多种不同的算法，最常用的就是等差数列求和。当然，也有更为简便的计算公式可以求出。 2、用差数列算法简单，（首项+末项）×项数÷2，带到1~99里就是（1+99）×99÷2=100×99÷2=99×50=4950。

4950 高斯的算法：1+99=100,2+98=100……49+51=100,共49对,余下50,所以为49*100+50=4950 等差数列求和公式也可以直接算出

n（n+1）/2=99*100/2=99×50=4950

A＝1+2+3+、、、+99B=99+98+97＝、、、+1将A+B=（1+99）+（2+98）+（3+97）+、、、+（99+1）＝100*99＝99009900/2＝4950

解答过程如下： （1+99）+（3+97）+……+（49+51） =100+100+……+100 =100x25 =2500 扩展资料 等差数列的求和方法： 方法是倒序相加 Sn=1+2+3+……+(n-1)+n Sn=n+(n-1)+(n-2)+……+2+1 两式相加 2Sn=(1+n)+(2+n-1)+(3+n-2)+……+(n-1+2)+(n+1)=(n+1)+(n+1)+(n+1)+……+(n+1)+(n+1) 一共n项(n+1) 2Sn=n(n+1) Sn=n(n+1)/2 倒序相加是数列求和中一种常规方法

1/100+2/100+……+99/10=（1/100)×（1+2+……+99）=(1/100)×（1+99）×99÷2=（1/100）×50×99=99/2

一加一一直加到99等于1+99+2+98+3+97.......+49+51+50=100X49+50=4950

提纲，是一种概括地叙述纲目、要点的公文。它不把全文的所有内容写出来，只把那些主要内容，提纲挈领式地写出来。 提纲使用于汇报工作、传达会议精神和讲话发言。因为有些情况、材料很繁杂，又很具体，而且本人对它也特别熟悉，这些具体材料都装在脑海里，用不着一一写出来，只需把纲目列出，就可把有关材料串联起来。提纲在工作中运用比较普遍，特别是人们都很繁忙，有时写材料，不把全文写出来，只写一个大体纲要，可以节省不少时间。一般形式为 总--分 形式，表格。提纲的主要特点有二:第一，纲要性。所谓纲要性，即把汇报、传达和发言的纲目、要点，提纲挈领地写出来，不把全文一字不漏地写到材料中去，因此，在写作中应突出"纲目"和"要点"这四个字。第二，条理性。所谓条理性，是说这种文字材料应该条理特别清楚，共有几个大问题，每个问题之下分几小点，一目了然，眉目清楚，否则，就失去了写提纲的作用。

（1）审清题意，确定主题　 先确定主题，因为提纲是整个全文的框架，主题不明确，等于群龙无首。　 确定作文题目，首先找出限制词和中心词，考虑题目要求、确定限制的范围。有些作文题目，本身已明显地表达出中心，要弄清楚它的限制词和中心词，就可以确定中心思想。如《记一个拾金不昧的同学》中，“一个”是限制词，中心词是“拾金不昧”，即要表达的中心思想。（2）围绕中心，选择材料要选择最能表现中心的材料，形成全文内容的有机联系。安排材料顺序常见的三种方法：一、按时间的先后顺序安排；二、按空间的变化顺序安排；三、按事情的重要程度安排。一般来说，记事的文章多按时间顺序列；写景、状物（建筑物之类）多按空间顺序列；写人（几方面品质、性格）和抒情的文章，多按事情的几个方面来列。但选用哪种方法列提纲，还要根据文章的中心和文章的具体内容写法来决定。（3）突出中心，详略得当根据表达中心的需要，安排所写材料的详略，能使文章重点突出，中心明确。凡是与文章中心关系密切、最能表现中心的材料，就是重点材料，应当详写，可在材料后面标上“详写”。对表现文章中心起辅助作用的材料，应当略写，可在材料后面标上“略写”。

可以这样写：I"mverysorryforthislatereplytoyoubecauseofmyillnessinthepastseveraldays.I"malsogladtoknowthatyourfriendagreed.YouplantobebackinChinaonJuly28,right?Asforinterviewdateandtime,IthinkwecoulddiscussaboutthemtogetherafteryouarriveinChina.Asyouaskedaboutfee,didyoumeanorganizationfeeinChina?Myfriendcalculateditinestimation;iftheeventisorganizedhere,theestimatedeventfeealtogetherisabout15,000AustralianDollars,accordingtocurrantexchangerate.Idon"tknowwhetheritischeaperormoreexpensivecomparedtoorganizingeventsinAustralia.Ifyouhaveanybetterideaspleaseletmeknow,andwecoulddiscussaboutitandthenmakeadecision.Pleaseletmeknowyourthoughts.Bytheway,Ienclosedtwopicturesforyouthistime,rightinthemailattachment.Pleasemindtocheckit.

C 考查非谓语动词。句意：已经下了几天的雨。衣服不得不被挂在火前弄干。Have to不得不，had后缺少不定式符号to。衣服是被挂的对象，故用被动语态。Hung的过去分词还是hung，故选C。

B 试题分析：短语辨析。A偶然；B处于困境；C落后；D故意；句意：正是因为已经连续下了好多天的雨，导致这个地区的洪水，也让很多村民处于缺失食物和庇护所的困境之中。根据句意说明B正确。点评：本题考查了介词的短语辨析，要根据上下文的语境辨析来确定所选择的短语，在平时要加强识记和辨析。

I am the monitor of our classes.Several days ago,I helped my teacher arrange the class trip to a sculpture park.We visit the sculpture park before the trip to note anything what may cause accidents.By doing so,my teacher and I knew what to expect and felt full prepared.There was 40students take the trip.My teacher and Idivided them groups of four,each group having one students in charge.The trip were really great-everyone came back happy and exciting.Although tired,but I felt very proud that我是我们班的班长。前几天，我帮我的老师安排到雕塑公园的班级旅行。我们参观雕塑公园之前要注意什么可能导致事故的旅行。这样，我和我的老师知道什么期望，觉得充分准备。有40的学生参加的旅行。我的老师和我将它们分为四组，每组负责一个学生。这次旅行真的很棒大家回来高兴和兴奋。虽然很累，但我感到很自豪

　　1英里=1.609344公里。英里是英制长度单位。从官方而言，它只应用于美国、利比里亚和缅甸。而其他GJ或地区则使用国际单位制，即米制，又称为公制。英国已于1995年完成了到国际单位制的转换。 　　 换算 　　1 英里 = 5 280 英尺 = 63 360 英寸 = 1 609.344 米 = 1760 码 = 1.609344千 米=1.609344公里。 　　1 英尺 = 12 英寸，3 英尺 = 1 码(yard)，5280 英尺 = 1 英里(Mile)。 　　1 英寸 = 2.54 厘米是英制长度与米制长度换算的基本关系。 　　 公里 　　公里指的就是千米。公里是中国对千米的通俗、广泛应用的叫法。1公里(千米)=1000米。 　　1790年5月由法国科学家组成的特别委员会，建议1米的长度定义为通过巴黎的子午线上从地球赤道到北极点的距离的千万分之一。1千米=1000米=10000分米=100000厘米。

have been busy fighting drought中有两个语法点： 首先,你需要知道固定搭配be busy doing something ,意思是“忙于做某事”； 然后,have done是现在完成时,表示从过去一直做到现在,而现在的状态是已经完成了这件事情. 望采纳.

1.609344公里。英美制长度单位，在古罗马，英里起源于“Millepassus”一语，意思是“一千步”。一名罗马士兵所迈出的一步，即左右脚各一步，被划分为5英尺，从而得出一英里等于5000英尺。使事情更加复杂的是，一英里还被分成8斯塔德，每一斯塔德等于625英尺。在几个世纪里，罗马“英里”的许多版本演变出来。

　　英语故事教学是小学英语教学中的一种重要方法,对学生综合语言运用能力的发展起着重要作用。我整理了7分钟英语故事，欢迎阅读! 　　7分钟英语故事篇一 　　The fox and the horse 　　A peasant had a faithful horse which had grown old and could do no more work, so his master no longer wanted to give him anything to eat and said, "I can certainly make no more use of you, but still I mean well by you, and if you prove yourself still strong enough to bring me a lion here, I will maintain you. But for now get out of my stable." And with that he chased him into the open field. 　　The horse was sad, and went to the forest to seek a little protection there from the weather. There the fox met him and said, "Why do you hang your head so, and go about all alone?" 　　"Alas," replied the horse, "greed and loyalty do not dwell together in one house. My master has forgotten what services I have performed for him for so many years, and because I can no longer plow well, he will give me no more food, and has driven me out." 　　"Without giving you a chance?" asked the fox. 　　"The chance was a bad one. He said, if I were still strong enough to bring him a lion, he would keep me, but he well knows that I cannot do that." 　　The fox said, "I will help you. Just lie down, stretch out as if you were dead, and do not stir." 　　The horse did what the fox asked, and then the fox went to the lion, who had his den not far off, and said, "A dead horse is lying out there. Just come with me, and you can have a rich meal." 　　The lion went with him, and when they were both standing by the horse the fox said, "After all, it is not very comfortable for you here —— I tell you what —— I will fasten it to you by the tail, and then you can drag it into your cave and eat it in peace." 　　This advice pleased the lion. He positioned himself, and in order that the fox might tie the horse fast to him, he kept completely quiet. But the fox tied the lion"s legs together with the horse"s tail, and twisted and fastened everything so well and so strongly that no amount of strength could pull it loose. When he had finished his work, he tapped the horse on the shoulder and said, "Pull, white horse, pull!" 　　Then up sprang the horse at once, and pulled the lion away with him. The lion began to roar so that all the birds in the forest flew up in terror, but the horse let him roar, and drew him and dragged him across the field to his master"s door. When the master saw the lion, he was of a better mind, and said to the horse, "You shall stay with me and fare well." And he gave him plenty to eat until he died. 　　狐狸和马 　　一个农夫有一匹勤勤恳恳、任劳任怨为他干活的马,但这匹马现在已经老了,干活也不行了,所以,农夫不想再给马吃东西.他对马说:“我再也用不着你了,你自己离开马厩走吧,到你比一头狮子更强壮时,我自然会把你牵回来的.” 　　说完,他打开门,让马自己去谋生去了. 　　这匹可怜的马非常悲哀,它在森林里茫无目标地到处徘徊,寒风夹着细雨,更增加了它的痛楚,它想寻找一个小小的避雨处.不久,它遇到了一只狐狸,狐狸问它:“我的好朋友,你怎么了?为甚么垂头丧气,一副孤苦伶仃、愁眉苦脸的样子呢?”马叹了一口气回答说:“哎——!公正和吝啬不能住在一间房子里.我的主人完全忘了我这许多年为他辛辛苦苦所干的一切,因为我不能再干活了,他就把我赶了出来,说除非我变得比一头狮子更强壮,他才会重新收留我.我有这样的能力吗?其实,主人是知道我没有这样的能力的,要不然,他也不会这样说了.” 　　狐狸听了之后,要它别愁了,只管放心,说道:“我来帮助你,你躺在那儿,把身子伸直,装做死了的样子,我自有办法.”马按狐狸的吩咐做了.狐狸跑到狮子住的洞口边,对狮子说:“狮子大王,有条小路上躺着一匹死马,我们一同去,你可以作一顿很不错的午餐来享受哩.”狮子听了非常高兴,立即就动身了. 　　它们来到马躺的地方,狐狸说:“在这儿你吃不完它,我告诉你怎么办:先让我把它的尾巴牢牢地绑在你的身上,然后你就能够将它拖回你的洞穴去慢慢地享用了.”狮子对这个建议很欣赏.於是它一动不动地躺下来,让狐狸把它绑在马背上.但狐狸却设法将它的腿捆在一起,用最大的力气把狮子牢牢地捆作一团,狮子没法挣脱束缚了. 　　一切料理完毕,狐狸拍了拍马的肩背说道:“起来吧!老马头,你可以走了!”那匹马跳起来,把狮子拖在尾巴后面离开了.狮子知道上了狐狸的当,开始咆哮吼叫起来,巨大的吼声把树上所有的鸟儿都吓得飞走了.但老马随便它怎么叫,只管自己慢慢悠悠地走过田野,终於把狮子拖到了主人的屋里. 　　它对主人说:“主人,狮子在这儿,我把它料理妥当了.”当主人看见它的这匹老马后,对它产生了怜悯之心,说道:“你就住在马厩里吧,我会好好待你的.”於是,这匹可怜的老马又有了吃的东西,主人一直供养它到死去. 　　7分钟英语故事篇二 　　The real pearl necklace 　　Jenny was a bright-eyed, pretty five-year-old girl. 　　One day when she and her mother were checking out at the grocery store, Jenny saw a plastic pearl necklace priced at $2.50. How she wanted that necklace, and when she asked her mother if she would buy it for her, her mother said, "Well, it is a pretty necklace, but it costs an awful lot of money. I"ll tell you what. I"ll buy you the necklace, and when we get home we can make up a list of chores that you can do to pay for the necklace. 　　And don"t forget that for your birthday Grandma just might give you a whole dollar bill, too. Okay?" Jenny agreed, and her mother bought the pearl necklace for her. 　　Jenny worked on her chores very hard every day, and sure enough, her grandma gave her a brand-new dollar bill for her birthday. Soon Jenny had paid off the pearls. How Jenny loved those pearls. She wore them everywhere to kindergarten, bed and when she went out with her mother to run errands. 　　The only time she didn"t wear them was in the shower. Her mother had told her that they would turn her neck green! 　　Jenny had a very loving daddy. When Jenny went to bed, he would get up from his favorite chair every night and read Jenny her favorite story. 　　One night when he finished the story, he said, "Jenny, do you love me?" 　　"Oh yes, Daddy, you know I love you," the little girl said. 　　"Well, then, give me your pearls." 　　"Oh! Daddy, not my pearls!" Jenny said. "But you can have Rosy, my favorite doll. Remember her? You gave her to me last year for my birthday. And you can have her tea party outfit, too. Okay?" 　　"Oh no, darling, that"s okay."Her father brushed her cheek with a kiss. "Good night, little one." 　　A week later, her father once again asked Jenny after her story, "Do you love me?" 　　"Oh yes, Daddy, you know I love you." 　　"Well, then, give me your pearls. " 　　"Oh, Daddy, not my pearls! But you can have Ribbons, my toy horse. Do you remember her? She"s my favorite. Her hair is so soft, and you can play with it and braid it and everything. You can have Ribbons if you want her, Daddy," the little girl said to her father. 　　"No, that"s okay," her father said and brushed her cheek again with a kiss. "God bless you, little one. Sweet dreams." 　　Several days later, when Jenny"s father came in to read her a story, Jenny was sitting on her bed and her lip was trembling." Here, Daddy," she said, and held out her hand. She opened it and her beloved pearl necklace was inside. She let it slip into her father"s hand. 　　With one hand her father held the plastic pearls and the other he pulled out of his pocket a blue velvet box. Inside of the box were real, genuine, beautiful pearls. He had had them all along. He was waiting for Jenny to give up the cheap stuff so he could give her the real thing. 　　7分钟英语故事篇三 　　心灵来自天使的爱抚 　　It was only a few weeks after my surgery, and I went to Dr. Belt"s office for a checkup. It was just after my first chemotherapy(化学疗法) treatment. 　　My scar was still very tender. My arm was numb underneath. This whole set of unique and weird sensations was like having a new roommate to share the two-bedroom apartment formerly known as my breasts - now lovingly known as "the breast and the chest." 　　As usual, I was taken to an examination room to have my blood drawn, again - a terrifying process for me, since I"m so frightened of needles. 　　I lay down on the examining table. I"d worn a big plaid flannel shirt and a camisole underneath. It was a carefully thought out costume that I hoped others would regard as a casual wardrobe choice. The plaid camouflaged my new chest, the camisole protected it and the buttons on the shirt made for easy medical access. 　　Ramona entered the room. Her warm sparkling smile was familiar, and stood out in contrast to my fears. I"d first seen her in the office a few weeks earlier. She wasn"t my nurse on that day, but I remember her because she was laughing. She laughed in deep, round and rich tones. I remember wondering what could be so funny behind that medical door. What could she possibly find to laugh about at a time like this? So I decided she wasn"t serious enough about the whole thing and that I would try to find a nurse who was. But I was wrong. 　　This day was different. Ramona had taken my blood before. She knew about my fear of needles, and she kindly hid the paraphernalia under a magazine with a bright blue picture of a kitchen being remodeled. As we opened the blouse and dropped the camisole, the catheter on my breast was exposed and the fresh scar on my chest could be seen. 　　She said, "How is your scar healing?" 　　I said, "I think pretty well. I wash around it gently each day." The memory of the shower water hitting my numb chest flashed across my face. 　　She gently reached over and ran her hand across the scar, examining the smoothness of the healing skin and looking for any irregularities. I began to cry gently and quietly. She brought her warm eyes to mine and said, "You haven"t touched it yet, have you?" And I said, "No." 　　So this wonderful, warm woman laid the palm of her golden brown hand on my pale chest and she gently held it there. For a long time. I continued to cry quietly. In soft tones she said, "This is part of your body. This is you. It"s okay to touch it." But I couldn"t. So she touched it for me. The scar. The healing wound. And beneath it, she touched my heart.Then Ramona said, "I"ll hold your hand while you touch it." So she placed her hand next to mine, and we both were quiet. That was the gift that Ramona gave me. 　　That night as I lay down to sleep, I gently placed my hand on my chest and I left it there until I dozed off. I knew I wasn"t alone. We were all in bed together,metaphorically(隐喻地) speaking, my breast, my chest, Ramona"s gift and me.

英里又称哩，是使用于英国、前英国殖民地和英联邦国家的长度单位。美国等国家采用。在香港，“英里”通常写作“哩”或“咪”（mile的音译），虽然这单位现在已极少使用。“哩”是近代新造的字，借用中国传统的长度单位“里”，并加口旁以示区别。1 英里 = 5 280 英尺 = 63 360 英寸 = 1 609.344 米=1.609344公里

A．That"s too bad 意思为"那太不好了"； B．I"m sorry to hear that意思为"听到这个我很遗憾"； C．How terrible意思为"多么糟糕"； D．Never mind意思为"没关系"． 根据情境可知听到了对方不好的事情，表示遗憾，故选B．

1 英里 = 5 280 英尺 = 63 360 英寸 = 1 609.344 米=1.609344公里

1海里＝1.852公里1英里＝1.60934公里现在国际上通用的是1节＝1海里／小时，1海里＝1.852公里。1节也就是1.852公里/小时

提纲，是一种概括地叙述纲目、要点的公文。它不把全文的所有内容写出来，只把那些主要内容，提纲挈领式地写出来。 提纲使用于汇报工作、传达会议精神和讲话发言。因为有些情况、材料很繁杂，又很具体，而且本人对它也特别熟悉，这些具体材料都装在脑海里，用不着一一写出来，只需把纲目列出，就可把有关材料串联起来。

作文提纲就是将课文中的大致内容拟成一个条款，清晰明了地知道文章的主要内容与结构还有人物等一系列的品质。作文提纲好比盖房子的框架，他的的形式一般有两种。 1．标题式提纲 这种提纲比较简单，只写出行文各段的标题。 这是一个标题式的作文提纲，勇简洁的文字标出了各段的写作要点。它的特点是文字简洁、速度较快，适合于对写作内容较熟悉或时间较紧的情况。但对初学写作的人来说，很难起到指导作文的作用。 2.要点式提纲 这种提纲比较详细，它即要表明作文的中心，又要写出作文的大致内容；同时，还要交代出文章的详略。 （三）编写提纲的要求 1.要审清题目，确定中心，选择材料 作文提纲是写好作文的基础，编写作文提纲要按照写作文的三个顺序：审清题目、确立中心，选择材料来进行。 作文题目一般给我们规定了写作范围（记人、记事、写景、状物等）、写作问题（记叙文、说明文、议论文），所以，审清题目，才能明确写什么、怎么写，才能避免文不对题、偏离中心的毛病。 中心思想是一篇文章的灵魂，在编写作文提纲式时，只有确立了中心，才能围绕选材，确定重点，安排详略，等等。选材时要注意紧紧围绕文章的中心思想，选择真实可信、新鲜有趣的材料，以使文章中心思想鲜明、深刻地表现出来。 2.要简洁明了 作文提纲只是作文的一个思路，一个框架。因此作文提纲既要完整，又不能过于繁琐；既要简洁，又要达到写作目的。 楼主要的例子有： 叙事类作文： 一、起因 二、经过 三、高潮 四、结果 写人类作文： 一、外貌 二、性格 三、事例 四、品质
