大侠请问您我这有主含量为99.5,那五氧化二磷和氧化钾的含量是多少、谢谢

根号55的倒数=5根号5=根号5
根号2约为1.414,根号3约为1.732,所以两者之间一个有理数可为1.5,无理数可为（根号2+根号3）/2
根号5约为2.236,所以-1-根号5约为-3.236,所以两者之间的整数位-3,-2,-1
(x-1)^3=-27/8=(-3/2)^3,所以x-1=-3/2,x=-1/2
”根号144“表示算术平方根,只能等于12,所以很容易判断BC错,正确的应该是D
显然是4个,当Q为1时,P为3或-1；当Q为-1时,P为-3或1
（1）根号121=11,³ 根号-27=-3,所以答案=14；（2）这个不能算了吧,如果用小数约的话,根号2为1.414,根号3约为1.732,³ 根号3约为1.442,所以结果为1.124
9<15<16,所以3<根号15<4,所以根号15整数部分为3,小数部分为根号15-3,所以2+根号15整数部分为5,小数部分仍为根号15-3
根号[n+1/(n+2)]=(n+1)*根号[(1/n+2)],这个自己也可以推导出来

这个剧本是莫泊桑的《项链》,大概意思就是一个女的为了在舞会更漂亮,借了条项链,结果弄丢了,那项链很贵,她不敢给项链的主人说,就花20年打工,最后买了条新的还给别人.结果那人却给她说借给她的是赝品,不贵.她就白辛苦了这么久.这个故事应该都听说过的,我这里的是英语的剧本,翻译的话你可以找网站po上去翻就可以了.
Necklace
The girl was one of those pretty and charming young creatures who sometimes are born, as if by a slip of fate, into a family of clerks. She had no dowry, no expectations, no way of being known, understood, loved, married by any rich and distinguished man; so she let herself be married to a little clerk of the Ministry of Public Instruction.
She dressed plainly because she could not dress well, but she was unhappy as if she had really fallen from a higher station; since with women there is neither caste nor rank, for beauty, grace and charm take the place of family and birth. Natural ingenuity, instinct for what is elegant, a supple mind are their sole hierarchy, and often make of women of the people the equals of the very greatest ladies.
Mathilde suffered ceaselessly, feeling herself born to enjoy all delicacies and all luxuries. She was distressed at the poverty of her dwelling, at the bareness of the walls, at the shabby chairs, the ugliness of the curtains. All those things, of which another woman of her rank would never even have been conscious, tortured her and made her angry. The sight of the little Breton peasant who did her humble housework aroused in her despairing regrets and bewildering dreams. She thought of silent antechambers hung with Oriental tapestry, illumined by tall bronze candelabra, and of two great footmen in knee breeches who sleep in the big armchairs, made drowsy by the oppressive heat of the stove. She thought of long reception halls hung with ancient silk, of the dainty cabinets containing priceless curiosities and of the little coquettish perfumed reception rooms made for chatting at five o'clock with intimate friends, with men famous and sought after, whom all women envy and whose attention they all desire.
When she sat down to dinner, before the round table covered with a tablecloth in use three days, opposite her husband, who uncovered the soup tureen and declared with a delighted air, "Ah, the good soup! I don't know anything better than that," she thought of dainty dinners, of shining silverware, of tapestry that peopled the walls with ancient personages and with strange birds flying in the midst of a fairy forest; and she thought of delicious dishes served on marvellous plates and of the whispered gallantries to which you listen with a sphinxlike smile while you are eating the pink meat of a trout or the wings of a quail.
She had no gowns, no jewels, nothing. And she loved nothing but that. She felt made for that. She would have liked so much to please, to be envied, to be charming, to be sought after.
She had a friend, a former schoolmate at the convent, who was rich, and whom she did not like to go to see any more because she felt so sad when she came home.
But one evening her husband reached home with a triumphant air and holding a large envelope in his hand.
"There," said he, "there is something for you."
She tore the paper quickly and drew out a printed card which bore these words:
The Minister of Public Instruction and Madame Georges Ramponneau
request the honor of M. and Madame Loisel's company at the palace of
the Ministry on Monday evening, January 18th.
Instead of being delighted, as her husband had hoped, she threw the invitation on the table crossly, muttering:
"What do you wish me to do with that?"
"Why, my dear, I thought you would be glad. You never go out, and this is such a fine opportunity. I had great trouble to get it. Every one wants to go; it is very select, and they are not giving many invitations to clerks. The whole official world will be there."
She looked at him with an irritated glance and said impatiently:
"And what do you wish me to put on my back?"
He had not thought of that. He stammered:
"Why, the gown you go to the theatre in. It looks very well to me."
He stopped, distracted, seeing that his wife was weeping. Two great tears ran slowly from the corners of her eyes toward the corners of her mouth.
"What's the matter? What's the matter?" he answered.
By a violent effort she conquered her grief and replied in a calm voice, while she wiped her wet cheeks:
"Nothing. Only I have no gown, and, therefore, I can't go to this ball. Give your card to some colleague whose wife is better equipped than I am."
He was in despair. He resumed:
"Come, let us see, Mathilde. How much would it cost, a suitable gown, which you could use on other occasions--something very simple?"
She reflected several seconds, making her calculations and wondering also what sum she could ask without drawing on herself an immediate refusal and a frightened exclamation from the economical clerk.
Finally she replied hesitating:
"I don't know exactly, but I think I could manage it with four hundred francs."
He grew a little pale, because he was laying aside just that amount to buy a gun and treat himself to a little shooting next summer on the plain of Nanterre, with several friends who went to shoot larks there of a Sunday.
But he said:
"Very well. I will give you four hundred francs. And try to have a pretty gown."
The day of the ball drew near and Madame Loisel seemed sad, uneasy, anxious. Her frock was ready, however. Her husband said to her one evening:
"What is the matter? Come, you have seemed very queer these last three days."
And she answered:
"It annoys me not to have a single piece of jewelry, not a single ornament, nothing to put on. I shall look poverty-stricken. I would almost rather not go at all."
"You might wear natural flowers," said her husband. "They're very stylish at this time of year. For ten francs you can get two or three magnificent roses."
She was not convinced.
"No; there's nothing more humiliating than to look poor among other women who are rich."
"How stupid you are!" her husband cried. "Go look up your friend, Madame Forestier, and ask her to lend you some jewels. You're intimate enough with her to do that."
She uttered a cry of joy:
"True! I never thought of it."
The next day she went to her friend and told her of her distress.
Madame Forestier went to a wardrobe with a mirror, took out a large jewel box, brought it back, opened it and said to Madame Loisel:
"Choose, my dear."
She saw first some bracelets, then a pearl necklace, then a Venetian gold cross set with precious stones, of admirable workmanship. She tried on the ornaments before the mirror, hesitated and could not make up her mind to part with them, to give them back. She kept asking:
"Haven't you any more?"
"Why, yes. Look further; I don't know what you like."
Suddenly she discovered, in a black satin box, a superb diamond necklace, and her heart throbbed with an immoderate desire. Her hands trembled as she took it. She fastened it round her throat, outside her high-necked waist, and was lost in ecstasy at her reflection in the mirror.
Then she asked, hesitating, filled with anxious doubt:
"Will you lend me this, only this?"
"Why, yes, certainly."
She threw her arms round her friend's neck, kissed her passionately, then fled with her treasure.
The night of the ball arrived. Madame Loisel was a great success. She was prettier than any other woman present, elegant, graceful, smiling and wild with joy. All the men looked at her, asked her name, sought to be introduced. All the attaches of the Cabinet wished to waltz with her. She was remarked by the minister himself.
She danced with rapture, with passion, intoxicated by pleasure, forgetting all in the triumph of her beauty, in the glory of her success, in a sort of cloud of happiness comprised of all this homage, admiration, these awakened desires and of that sense of triumph which is so sweet to woman's heart.
She left the ball about four o'clock in the morning. Her husband had been sleeping since midnight in a little deserted anteroom with three other gentlemen whose wives were enjoying the ball.
He threw over her shoulders the wraps he had brought, the modest wraps of common life, the poverty of which contrasted with the elegance of the ball dress. She felt this and wished to escape so as not to be remarked by the other women, who were enveloping themselves in costly furs.
Loisel held her back, saying: "Wait a bit. You will catch cold outside. I will call a cab."
But she did not listen to him and rapidly descended the stairs. When they reached the street they could not find a carriage and began to look for one, shouting after the cabmen passing at a distance.
They went toward the Seine in despair, shivering with cold. At last they found on the quay one of those ancient night cabs which, as though they were ashamed to show their shabbiness during the day, are never seen round Paris until after dark.
It took them to their dwelling in the Rue des Martyrs, and sadly they mounted the stairs to their flat. All was ended for her. As to him, he reflected that he must be at the ministry at ten o'clock that morning.
She removed her wraps before the glass so as to see herself once more in all her glory. But suddenly she uttered a cry. She no longer had the necklace around her neck!
"What is the matter with you?" demanded her husband, already half undressed.
She turned distractedly toward him.
"I have--I have--I've lost Madame Forestier's necklace," she cried.
He stood up, bewildered.
"What!--how? Impossible!"
They looked among the folds of her skirt, of her cloak, in her pockets, everywhere, but did not find it.
"You're sure you had it on when you left the ball?" he asked.
"Yes, I felt it in the vestibule of the minister's house."
"But if you had lost it in the street we should have heard it fall. It must be in the cab."
"Yes, probably. Did you take his number?"
"No. And you--didn't you notice it?"
"No."
They looked, thunderstruck, at each other. At last Loisel put on his clothes.
"I shall go back on foot," said he, "over the whole route, to see whether I can find it."
He went out. She sat waiting on a chair in her ball dress, without strength to go to bed, overwhelmed, without any fire, without a thought.
Her husband returned about seven o'clock. He had found nothing.
He went to police headquarters, to the newspaper offices to offer a reward; he went to the cab companies--everywhere, in fact, whither he was urged by the least spark of hope.
She waited all day, in the same condition of mad fear before this terrible calamity.
Loisel returned at night with a hollow, pale face. He had discovered nothing.
"You must write to your friend," said he, "that you have broken the clasp of her necklace and that you are having it mended. That will give us time to turn round."
She wrote at his dictation.
At the end of a week they had lost all hope. Loisel, who had aged five years, declared:
"We must consider how to replace that ornament."
The next day they took the box that had contained it and went to the jeweler whose name was found within. He consulted his books.
"It was not I, madame, who sold that necklace; I must simply have furnished the case."
Then they went from jeweler to jeweler, searching for a necklace like the other, trying to recall it, both sick with chagrin and grief.
They found, in a shop at the Palais Royal, a string of diamonds that seemed to them exactly like the one they had lost. It was worth forty thousand francs. They could have it for thirty-six.
So they begged the jeweler not to sell it for three days yet. And they made a bargain that he should buy it back for thirty-four thousand francs, in case they should find the lost necklace before the end of February.
Loisel possessed eighteen thousand francs which his father had left him. He would borrow the rest.
He did borrow, asking a thousand francs of one, five hundred of another, five louis here, three louis there. He gave notes, took up ruinous obligations, dealt with usurers and all the race of lenders. He compromised all the rest of his life, risked signing a note without even knowing whether he could meet it; and, frightened by the trouble yet to come, by the black misery that was about to fall upon him, by the prospect of all the physical privations and moral tortures that he was to suffer, he went to get the new necklace, laying upon the jeweler's counter thirty-six thousand francs.
When Madame Loisel took back the necklace Madame Forestier said to her with a chilly manner:
"You should have returned it sooner; I might have needed it."
She did not open the case, as her friend had so much feared. If she had detected the substitution, what would she have thought, what would she have said? Would she not have taken Madame Loisel for a thief?
Thereafter Madame Loisel knew the horrible existence of the needy. She bore her part, however, with sudden heroism. That dreadful debt must be paid. She would pay it. They dismissed their servant; they changed their lodgings; they rented a garret under the roof.
She came to know what heavy housework meant and the odious cares of the kitchen. She washed the dishes, using her dainty fingers and rosy nails on greasy pots and pans. She washed the soiled linen, the shirts and the dishcloths, which she dried upon a line; she carried the slops down to the street every morning and carried up the water, stopping for breath at every landing. And dressed like a woman of the people, she went to the fruiterer, the grocer, the butcher, a basket on her arm, bargaining, meeting with impertinence, defending her miserable money, sou by sou.
Every month they had to meet some notes, renew others, obtain more time.
Her husband worked evenings, making up a tradesman's accounts, and late at night he often copied manuscript for five sous a page.
This life lasted ten years.
At the end of ten years they had paid everything, everything, with the rates of usury and the accumulations of the compound interest.
Madame Loisel looked old now. She had become the woman of impoverished households--strong and hard and rough. With frowsy hair, skirts askew and red hands, she talked loud while washing the floor with great swishes of water. But sometimes, when her husband was at the office, she sat down near the window and she thought of that gay evening of long ago, of that ball where she had been so beautiful and so admired.
What would have happened if she had not lost that necklace? Who knows? who knows? How strange and changeful is life! How small a thing is needed to make or ruin us!
But one Sunday, having gone to take a walk in the Champs Elysees to refresh herself after the labors of the week, she suddenly perceived a woman who was leading a child. It was Madame Forestier, still young, still beautiful, still charming.
Madame Loisel felt moved. Should she speak to her? Yes, certainly. And now that she had paid, she would tell her all about it. Why not?
She went up.
"Good-day, Jeanne."
The other, astonished to be familiarly addressed by this plain good-wife, did not recognize her at all and stammered:
"But--madame!--I do not know--You must have mistaken."
"No. I am Mathilde Loisel."
Her friend uttered a cry.
"Oh, my poor Mathilde! How you are changed!"
"Yes, I have had a pretty hard life, since I last saw you, and great poverty--and that because of you!"
"Of me! How so?"
"Do you remember that diamond necklace you lent me to wear at the ministerial ball?"
"Yes. Well?"
"Well, I lost it."
"What do you mean? You brought it back."
"I brought you back another exactly like it. And it has taken us ten years to pay for it. You can understand that it was not easy for us, for us who had nothing. At last it is ended, and I am very glad."
Madame Forestier had stopped.
"You say that you bought a necklace of diamonds to replace mine?"
"Yes. You never noticed it, then! They were very similar."
And she smiled with a joy that was at once proud and ingenuous.
Madame Forestier, deeply moved, took her hands.
"Oh, my poor Mathilde! Why, my necklace was paste! It was worth at most only five hundred francs!"

The history of western art is such a history written with light,
so interpreting western art can start from the meaning of "light" in cultural and spiritual field, especially the art of Christian church architecture. The article takes the “light” design of Christian churches as a clue, analyzes the “ChurchofLight” designed by Tadao Ando and his design philosophy. It is considered that the work is a logical development of the medieval church such as “The Light of God," and the Ronchamp church such as "The Light of Reason", and agrees with the tide that the post-modernist art
emphasizes on "communication" and "dialogue". The design of Tadao Ando's "Church ofLight" is the reversion of "humanity", what it reflects is "the light of humanity."

If I were God I would do all the things I'd like to do.
I would never go to work or pay attention to some jerk
I would jump from every mountain.
I would sail the seven seas
I would fly up in the sky
I would see all the things I never see
I would always be with you and make all your dreams come true
I would fill your days with laughter
I would live a million years
We'd be happy ever after
They would never see our tears
Guess how wonderful it would be

我觉得你是不是在说,直径为1.83m,油罐高4.56m,剩下的油的高度是1.24m,问还剩下多少油啊?
如果是这样的话,就用
（油罐的高-剩下油的高）x 油罐底圆面积
=（4.56m-1.24m) × 【π ×(1.83m)²】
=11.118348πm³
=看四舍五入有没有要求,如果有按要求做,若没有,普遍保留3位,还有看要求有没有说要把π乘出来,原题上有没有写明π等于3.14之类的.

计算极限
关于计算极限，是不是只要把lim下面的数字直接代进式就可以啦，在什么样的情况下不能直接代呢？？
如果函数是连续函数,且在求极限的点有定义,就可以直接代入.例如lim(x->1)x²=1²=1
lim (x+h)平方-x平方/h
h--0
=lim(2hx+h²)/h=lim(2x+h)=2x
h-->0 h-->0
lim (1+1/2+1/4+…2的n次方)
n--无穷
=lim(1-(1/2)^(n+1))/(1-1/2)
n-->∞
=lim2(1-(1/2)^(n+1))
n-->∞
=lim2-lim(1/2)^n
n-->∞n-->∞
=2-0
=2

lim 1/（1-x）-3/1-x的3次方)
x--1
=lim((1+x+x²-3)/(1-x^3)
x-->1
=lim(x²+x-2)/(1-x)(1+x+x²)
x-->1
=lim(x-1)(x+2)/(1-x)(1+x+x²)
x-->1
==lim-(x+2)/(1+x+x²)
x-->1
=-3/4
证明：当x-->0时 secX-1~ x平方/2
lim2(secx-1)/x²
x-->0
由于分子分母同时趋进于0,有洛比达法则,分子分母同时求导
=limsecxtanx/x
x-->0
=limsinx/xcos²x
x--)0
=limcosx/(cos²x-2xcosxsinx)
x-->0
=1
所以secX-1~ x平方/2
lim arctanX/sin4X ，洛比达法则比较
x--0
=lim1/（1+x²)(4cos4x)
x-->0
=1/4
=lim (tanX-sinX)/(sinX)^3
x--0
=lim (1/cosx-1/sin²x)
x-->0
=lim(1-cosx)/(1-cos²x)cosx
x-->0
=lim1/(1+cosx)cosx
x-->0
=1/2
指出下列函数在指出的点属于哪类间断点，如果是可去间断点，补充或改变函数的定义使其连续
(1) y=x平方-1/x平方-3x+2 x=1 x=2
y=(x²-1)/(x²-3x+2)
=(x+1)(x-1)/(x-2)(x-1)
=(x+1)/(x-2)
所以x=2为无穷间断点,x=1为可去间断点，补充x=1时，y=-2
函数连续。
(2) y=x/tanX x=k派 x=k派+派/2(k=0,正负1，正负3…)
y=xcosx/sinx
sinx=0时的点即x=kπ的点为无穷间断点，不可去
cosx=0时的点即x=kπ+π/2时的点为可取间断点，补充定义
当x=kπ+π/2，y=0
证明方程
X=asinX+b 其中a>0,b>0 至少有一个正根，并且它不超过a不等于b
题目似乎有问题,应该为
证明：x=asinx+b(a>0,b>0)至少有一个正根，且不超过a+b
设f（x）=x-asinx-b，
则f（x）为连续函数。
f（0）=-b0。

1.高 空 弹 跳
Bungee jumping looks like fun.It makes me nervous just to watch someone do it.It certainly takes a lot of guts to jump one thousand feet above the water with only a rope tied to your legs.It scares me just to think about it.However,it is something I really want to do one day．
Some people think I'm crazy.They say to jump is foolish enough,but to have to pay for it is madness.I don't agree.For me,to live a short and exciting life is far better than to live a long and boring one.What do you think?
高空弹跳看起来蛮好玩的.光是看别人做这件事就会让我紧张.双腿只用一条绳索绑着,从水面上一千尺的高度跳下的确需要很大的胆量.光是想到这点就够让我害怕的了.可是,这是我总有一天真的想做的事.
有些人认为我疯了.他们说去跳就已经够蠢了,而还要付钱则不啻为疯狂的行为.我并不同意.对我来说,过个短暂而剌激的生活比过漫长却无聊的日子好得多.你认为呢?
2.BOOKS 书籍
As is well known,books teach us to learn life,truth,science and many other useful things.They increase our knowledge,broaden our minds and strengthen our character.In other words,they are our good teachers and wise friends.This is the reason why our parents always encourage us to read more books.Reading is a good thing,but we must pay great attention to the choice of books.It is true that we can derive benefits from good books.However,bad books will do us more harm than good.如众所周知,书籍教我们学习人生,真理,科学以及其它许多有用的东西.它们增加我们的知识,扩大我们的心胸并加强我们的品格.换句话说,它们是我们的良师益友.这是为什么我们的父母终是鼓励我们要多读书的理由.读书是一好事,但我们必须多加注意书的选择.不错,我们能从好书中获得益处.然而,坏书却对我们有害无益.

选because 我是英语专业的,这么跟你说吧.
since 作因为来说,一般放在句首
as也放在句首
只有because既可以句首也可以句中
还有一个单词for,作因为这个意思来说,放在逗号后面

千（kilo）的英文缩写

1.去掉since.理由条件状语从句.since虽有因为的意思可以引导从句,但用在此处多余.楼上的说把Since换成because of,想法不错,但忽略了一点,because of后面只可以接短语不可以接句子.如果想用because也可以,去掉since being 就好了.
2.wear 换成wearing.理由：wear在此处做状语修饰the man.The man always wearing mask 做整个句子的主语.
英语语法是我高中学的,虽然大学也是选择英语专业,但对语法不像高中那么系统的去学了,现在毕业了,语法也差不多忘了.这个改错又激起了我学习的兴趣了.语法学习要一步一步来,真正学起来其实蛮简单的,不要把自己弄糊涂了,一句一句理清成分就好了.一个句子好比一棵大树,找出主杆,其他都是枝叶,不影响句子的表达的.每一成分像枝叶长在该长的位置就对了.

　　爱心可以让人受益非浅,但是在你付出你的爱心时,往往却是一个小小的不经意的细节.爱心可以来自不同的人,也可以是不同程度的关爱和关心同样也可以是来自素不相识的陌生人的关爱,在这种关爱里,我有着非常深刻的体会,
　　关爱他人可以从小事做起,譬如你帮助一个同学辅导功课,一个好老师的一句诤言或几句鼓励的话,往往能给学生带来不懈的动力,还比如你扶一个盲人过马路,陪老人谈心……这都是关爱他人的表现,如果你给予了别人关爱,那你自己心里都是美滋滋的.
　　老师对我们有关爱,她的爱是无私的!父母给予了我们关爱,他们的爱是伟大的!我们自己也要学会关爱,关爱别人,关爱自己!是啊!将心比心学会关爱,我们都爱自已的亲人,我们也希望亲人在困难的时候得到关爱.不是只我们爱亲人,人与人之间的感情一样都是深厚的.他们也爱自己的父母以及家人.可是如果人们都只想让自己以及家人困难时候得到关爱,而自己却不去关爱别人,如果人们都这样想,何来关爱他人呢?我们不能只奢求别人给予关爱,而自己却不在别人困难的时候给予关爱.只有我为人人,才有人人为我.我们应该学会关爱,当别人遇到了困惑的时候,希望我们的关怀像流水一样流进她的心田.我们都曾有美好的童年,也将会有白发苍苍的暮年.难道你希望像幼年时就算跌倒了,坐在那里哭哭啼啼也没人理你吗?难道你不希望在你白发苍苍的时候,几乎走不动路,有人扶你过马路吗?文明是靠大家共同维护的,不是靠个人完成的.不是有一首歌吗?只要人人都献出一点爱,世界将会变成美好的人间.亲爱的朋友们,不要吝啬你的爱.献出你的一份关爱,让我们共同手拉手走向美好的明天,我相信,在爱心的世界里,有你、有我、有她.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.我美丽,因为我有爱心.爱,就是关心爱护,它在我们身边无处不在.我们每个人都需要关爱,生活上也少不了关爱,别人给予我们关爱,那我们更应该去关心爱护他人,正所谓滴水之恩当涌泉相报.

【名师讲解】
1. in/on
在表示空间位置时,in表示在某个空间的范围以内,on表示在某一个物体的表面之上.例如：
There is a bird in the tree. 树上有只鸟.
There is a picture on the wall. 墙上有张图.
2. this/that/these/those
(1)this常常用来指在时间、地点上更接近讲话人的人和事,these是this的复数形式.that常常用来指在时间、地点上离讲话人更远一点的人和事,those时that的复数形式.例如：
You look in this box and I’ll look in that one over there.你看看这个盒子,我去看那边的那个盒子.
I want this car, not that car. 我想要这辆小汽车,不是那一辆.
Take these books to his room, please. 请把这些书拿到他房间去.
This is mine; that’s yours. 这个是我的,那个是你的.
These are apples; those are oranges. 这些是苹果,那些是橘子.
(2)在打电话的用语中,this常常指的是我,that常常指的是对方.例如：
This is Mary speaking. Who’s that? 我是玛丽.你是谁?
3. There be/ have
There be "有",其确切含意为"某处或某时存在某人或某物."其结构是：There be + 某人或某物 + 表示地点或时间的状语.There be 后面的名词实际上是主语,be 动词的形式要和主语在数上保持一致,be动词后面的名词是单数或不可数名词时用is,名词是复数时用are.例如：
(1) There is a big bottle of coke on the table. 桌上有一大瓶子可乐.
(2) There is a doll in the box. 那个盒子里有个娃娃.
(3) There are many apples on the tree. 那树上有许多苹果.
总之,There be结构强调的是一种客观存在的"有".have表示"拥有,占有,具有",即：某人有某物(sb. have / has sth.).主语一般是名词或代词,与主语是所属关系.例如：
(4) I have two brothers and one sister.我有两个兄弟,一个姐姐.
(5) That house has four rooms.那所房子有四个房间.
4. look/ see/ watch
(1)look 表示“看、瞧”,着重指认真看,强调看的动作,表示有意识地注意看,但不一定看到,以提醒对方注意.,如：
Look! The children are playing computer games. 瞧!孩子们在玩电脑游戏.
Look! What’s that over there? 看!那边那个是什么?
单独使用是不及物动词,如强调看某人/物,其后接介词at,才能带宾语,如：
He’s looking at me.他正在看着我.
(2)see强调“看”的结果,着重的是look这个动作的结果,意思是“看到”,see是及物动词,后面能直接跟宾语.如：
What can you see in the picture? 你能在图上看到什么?
Look at the blackboard. What did you see on it?看黑板!你看到了什么?
(3)watch“观看,注视”,侧重于场面,表示全神贯注地观看、观察或注视某事务的活动,强调过程,常用于“看电视、看足球、看演出”等.如：
Yesterday we watched a football match on TV.昨天我们从电视上看了一场足球比赛.
4. put on/ / in
put on意为“穿上,戴上”.主要指“穿上”这一动作, 后面接表示服装、鞋帽的名词.
in 是介词,表示“穿着”强调状态.在句中可以做定语、标语和状语.如：
It’s cold outside, put on your coat. 外面冷,穿上你的外衣.
He puts on his hat and goes out. 他戴上帽子,走了出去.
The woman in a white blouse is John’s mother.穿白色衬衣的那个妇女是John的妈妈.
5. house/ home/family

He is not at home. 他不在家.
My family all get up early. 我们全家都起得很早.
6. fine, nice, good, well
四者都可用作形容词表示"好"之意,但前三者既可作表语又可作定语,而后者仅用作表语.主要区别在于：
(1) fine指物时表示的是质量上的"精细",形容人时表示的是"身体健康",也
可以用来指"天气晴朗".例如：
Your parents are very fine. 你父母身体很健康.
That's a fine machine. 那是一台很好的机器.
It's a fine day for a walk today. 今天是散步的好时候.
(2)nice主要侧重于人或物的外表,有"美好","漂亮"的意思,也可用于问候或赞扬别人.例如：
Lucy looks nice. 露西看上去很漂亮.
These coats are very nice. 那些裙子很好看.
Nice to meet you. 见到你很高兴.
It's very nice of you. 你真好.
(3)good形容人时指"品德好",形容物时指"质量好",是表示人或物各方面都好的普通用语.例如：
Her son is a good student. 她儿子是一个好学生.
The red car is very good. 那辆红色小汽车很好.
(4)well只可用来形容人的"身体好",但不能作定语,它也能用作副词作状语,多放在所修饰的动词之后.例如：

叶子的度数为0；那么设叶子数为x，则此树的总分叉数为1*4+2*2+3*1+4*1=15；
此树的节点个数为16（此处涉及到一个公式;节点数=分叉数+1，由图形便可以观察出来）,又根据题目可以知道顶点数目还可以列出一个式子：4+2+1+1+x便可以得到等式：4+2+1+1+x=16；x=8为叶子数。
因为此题是数据结构中的问题：一般情况下都是有向树，所以叶子节点的度数为0，要区分于离散数学中的无向树叶子节点度为一。
在数据结构中一般常用的公式为：二叉树：度为0的节点数=度为2的节点数+1（n0=n2+1）此公式可由上述计算思想推导（一般在二叉树那里的公式多一些，树中只要你明确定义，划出图来，便可以根据图形寻找出规律来）

鼓泡:Bubble
阳极液浓度:Concentration of anodic solution
离子交换膜:Ion-exchange membrane
开停车:Start and Stop Production

在本题中,“上海金茂大厦主楼高88层”是个没有用的条件,所以不用考虑它.本道题的解法：求助楼高度,直接用“9×45=405m”,就好了~这是我的

任何人若生产、加工、销售含有转基因成分的食品、食品添加剂、动物饲料,或者这些产品是从转基因产品衍生而来的,则当引起民事责任时,当事人应当说明那些有问题的转基因物质或产品的进口来源地、产品的详细情况、使用条件、以及销售分布范围.

先回答（1）吧.做DE⊥BC于点E,则ADEB是矩形,在△DEC中,用勾股定理可求出DE=4,所以AB=DE=4,即圆O的直径等于4.
继续回答（2）吧.“平行四边形PQCD”这句话改为“四边形PQCD”吧.设其面积为S.
则S=(13-t+2t)×4÷2,S=2t+26（0＜t＜8）.
当四边形PQCD为等腰梯形时,结合（1）图可知,2t=13-t+3×2,解得t=19/3.

登封申遗景点古树护理
百余古树重点护理
6月21日,周六早上,登封市文物局副局长郑建伟再次上山,检查申遗景点内古树的防雨通风情况.
第一站是会善寺.“树身有多处朝天洞,树干部分坏死,土质较差.”和其他古树一样,寺门口那棵1500多岁银杏树的“病历”已经装进郑建伟等人的脑子里.
郑建伟称,申遗让嵩山古树名木群享受了一次全面“体检”.3个多月前,有关人员开始对包括银杏树在内的104棵古树进行“特级护理”,此外还有150棵古树成为重点护理对象.
换土,给树“吃”营养餐；坏死部分涂防护液,防止病虫侵害……绕树数周,看到银杏树现在树叶葱茏,高大挺拔,郑建伟欣然点头.
名木维护一树一策
“经过这一次全面治理,只要下一步维护工作跟得上,饱经沧桑的嵩山古树名木群将迎来第二春.”他说.
不过,参与治理维护工作的工作人员们知道这个过程并不容易.
譬如复壮,要讲究“科学进补”,用掺了肥料的营养土替换原来的土时,这1立方米左右的土要分4年才能替换完,否则树很可能就会出现不适反应.
古树患病不同,治疗方案也就不同,即便同样的病,树的情况不一,就得具体问题具体分析.譬如朝天洞,长在树杈上,用特殊木料填充,同时在树身底部疏通出一个通风孔即可,但像嵩阳书院门口的将军柏,长在了主干上,以至于整棵树腹中空空状若木桶,工作人员苦想数日,给洞口戴了一个防雨帽,将之命名为“烟囱疗法 ”.
“我们在专家指导下,摸索出一套自创的做法,为古树名木去病强身,总体效果相当好.”郑建伟说.
这套自创做法,首推“先体检后治病”,即先对土样、叶样进行分析,然后对症下药.上百次分析做下来,工作人员总结出一条条经验：侧柏集中的地方土质容易缺铁,树根上方地面用青砖铺地比用石板土质疏松,透气性好……
古树支架自然协调
让郑建伟最得意的是他提出的“治理应与周边环境相协调”一说,得到了古树名木治理组的一致肯定.
于是记者看到了这样的景象：在嵩岳寺,两根石柱支撑起那棵树身严重倾斜的老国槐,柱身做了仿树皮处理,远远望去和国槐宛若一体；中岳庙的狮子柏、三公柏都加了围栏,围栏以特殊木料制成,纹理清晰,古朴典雅,既保护了树,又方便游人小坐……
“它们长势如何,将直接反映出周边生态环境的优劣,来不得半点虚假啊!”郑建伟感慨地说.6
新闻背景
登封古树名木共有874棵,省内最多,现已全部建档,因分布在嵩山上下,被称为嵩山古树名木群.其中树龄在1000～4500年的有500余棵,最著名、最珍贵的嵩阳书院的两棵将军柏,树龄均在4500年以上.嵩山古树名木群被誉为活着的文物、有生命的国宝,具有很高的经济、历史、观赏、科研和文化价值.

如果是数学物理竞赛,微积分建议熟练掌握,尤其是物理竞赛（会占很大优势）.其中主要是极限、导数、一元函数微积分、简单的常微分方程、多元函数微分和多元函数极值问题.
学习微积分必须掌握其精髓,即极限的思想、微元的思想、变化的思想.这些思想对你深入思考问题（不仅仅是数学物理问题）的能力提高大有裨益,而不仅仅是一种解题技巧,本质上说是一种全新的世界观（动态的、变化的看问题,而不是静止的看问题）.如果你学习了微积分能悟到上面的道理,你将在高中至本科阶段无往不胜!话说回来,对很多人是这可能需要一个较长时间的认识过程,希望你是少数之一,你既然有志于参赛得奖,说明你相信自己的能力.
如果是化、生,微积分的思想固然同样有用,但你若未能领会其精髓,可能对解决问题并无明显帮助,与其花这么多时间学微积分往往不如就学化、生本身.
如果是数学竞赛,热力学基本没用,但对其他三门都很重要（热力学是讨论能量转化的学问,具有极大的普遍性,是任何自然科学的根基之一）.尤其对化学,你有了扎实的热力学基础,你对化学的理解将大大深入,会明显占据竞争优势（不过,最好学一学物理化学基础,它比热力学更贴近化学）.
知识总是学不完的,其它课程无法一一叙述,根据自己的具体情况决定.只能简要讨论你说的两门.

第一题应用过去完成时

第二个,第四个.

主语表示句子主要说明的人或事物,一般由名词.代词.数词.动名词.动词不定式等充当
谓语说明主语的动作,状态或特征.行为.
宾语表示动作行为的对象,跟在及物动词之后,能作宾语的有名词,代词,动名词,数词,动词不定式等.
例如：I eat an apple.
I为动作的发出者,主要说明的对象,为主语
eat为I的动作,是谓语
apple是跟在及物动词eat后,我吃的对象,为宾语
宾语从句：在句子中起宾语作用的从句叫做宾语从句
如I wonder who she is,
我想知道她是谁
I为主语,wonder为宾语,who she is跟在wonder后面做宾语结构,即为宾语从句

正方形的对角线长度相等,是因为他们都是正方形外接圆的直径.
正五边形的对角线是不一样长的,一共有两个长度的对角线,一种是外接圆的弦,另一种特殊是直径.
正多边形（N边形）的顶点将其外接圆均匀的分成了N段弧.由于在同一个圆内弧长相等地对应弦长也相等.所以正多边形才会有长度相同的对角线.
