McDonald's Corporation (NYSE:MCD) is the world's largest chain of fast-food restaurants,primarily selling hamburgers,chicken,french fries,milkshakes and soft drinks.More recently,it also offers salads,fruit and carrot sticks.
The business began in 1940,with a restaurant opened by siblings Dick and Mac McDonald in San Bernardino,California.Their introduction of the "Speedee Service System" in 1948 established the principles of the modern fast-food restaurant.The present corporation dates its founding to the opening of a franchised restaurant by Ray Kroc,in Des Plaines,Illinois on April 15,1955,the ninth McDonald's restaurant overall.Kroc later purchased the McDonald brothers' equity in the company and led its worldwide expansion.
With the successful expansion of McDonald's into many international markets,the company became a symbol of globalization and the spread of the American way of life.Its prominence also made it a frequent subject of public debates about obesity,corporate ethics and consumer responsibility.

按你的作文水平,看这个意思应该可以看懂了：
other：其他的,另外的
others：表示一定范围 ,比如知道BCD范围在A中,表示B用some,表示C用others,因为在A范围内还有D不知道,所以这时表示C范围用others.
the other：表示两者间的第二个.有个常用固定词组：one ...the other
any other：意思是“其他任何的” 随后名词+单数形式
another：意思是“再一个,另多一个”根据意思判断.

二元酸与二元醇或二元胺生成聚酯、聚酰胺的反应也属这种情况,称为缩合聚合反应.

1、用氢气的体积，换算成mol，推算铁的质量；剩下的才是CuO和Fe3O4的总和质量；假定这个数是A克；
2、铁和稀硫酸反应，生成的是二价铁离子；100g 24%的NaOH可以算出消耗的OH-的mol数；亚铁和铜都是二价，四氧化三铁是三价的，消耗的OH-比例会不同；用刚才算出的Fe粉的量，推算出二价铁消耗了多少OH-离子，剩下的就是氧化铜和四氧化三铁消耗的OH-的量；例如得出B克；
3、获得了氧化铜和四氧化三铁的总质量和OH-消耗的对应比例，需要用方程式计算两种物质的量，按照化学方程式的比例，假定X克氧化铜+Y克四氧化三铁，刚好和B克发生反应；用方程算X和Y各是多少，然后A、X、Y就是三种物质的比例，比例就是答案。
4、这个考的其实是思路和数学功底。

弓形 S＝r2/2·(πα/180-sinα)
＝r2arccos[(r-h)/r] - (r-h)(2rh-h2)1/2
＝παr2/360 - b/2·[r2-(b/2)2]1/2
＝r(l-b)/2 + bh/2
≈2bh/3
字母的含义：
l－弧长
b－弦长
h－矢高
r－半径
α－圆心角的度数
一般工作中如下常用简单方式计算：
S≈2bh/3=2*34.9*3/2=104.7平方米 该结果与精确计算的相差无几,可以采用.

scrub them in mountain water.
To a woman, I want to love
women you could turn into,
scrub them in mountain water,
stroke their astonishing faces.
Women you could turn into
the scare mask of Bad Mother
stroke their astonishing faces
in the silver-scratched sink mirror.
The scare mask of Bad Mother
crumbles to chunked, pinched clay,
sinks in the silver-scratched mirror.
You are the Little Robber Girl, who
crumbles the clay chunks, pinches
her friend, givers her a sharp knife.
You are the Little Robber Girl, who
was any witch’s youngest daughter.
Our friend gives you a sharp knife,
shows how the useful blades open.
Was any witch’s youngest daughter
golden and bold as you? You run and
show how the useful blades open.
You are the baby on the mountain. I am
golden and bold as you. You run and
we pace each other for a long time.
还有 tanka，rondeau，ballad， epistle，triolet，epigram，epic，ode，limerick，sonnet，sestina，等等。再给你一个sonnet的例子：
Shall I compare thee to a summer’s day? (Sonnet 18)
William Shakespeare, 1564 - 1616
Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate.
Rough winds do shake the darling buds of May,
And summer’s lease hath all too short a date.
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimmed;
And every fair from fair sometime declines,
By chance, or nature’s changing course, untrimmed;
But thy eternal summer shall not fade,
Nor lose possession of that fair thou ow’st,
Nor shall death brag thou wand’rest in his shade,
When in eternal lines to Time thou grow’st.
So long as men can breathe, or eyes can see,
So long lives this, and this gives life to thee.

同分异构现象广泛存在于有机物中,同分异构体的知识也贯穿于中学有机化学的始终.因此,分析、判断同分异构体也就成为有机化学的一大特点.作为高考命题的热点之一,这类试题是考查学生空间想象能力和结构式书写能力的重要手段.考生在平时训练中就应逐渐领会其中的本质,把握其中的规律.
一、书写同分异构体必须遵循的原理
“价键数守恒”原理：在有机物分子中碳原子的价键数为4,氧原子的价键数为2,氢原子的价键数为1,不足或超过这些价键数的结构都是不存在的,都是错误的.如：CH3CH2CH3（第2个碳原子形成5个价键是不可能的）|
CH3
二、同分异构体的种类
有机物产生同分异构体的本质在于原子的排列顺序不同,在中学阶段主要指下列三种情况：
⑴碳链异构：由于碳原子的连接次序不同而引起的异构现象,如CH3CHCH3和CH3CH2CH2CH3.
|
CH3
⑵官能团位置异构：由于官能团的位置不同而引起的异构现象,如：CH3CH2CH=CH2和CH3CH=CHCH3.
⑶官能团异类异构：由于官能团的不同而引起的异构现象,主要有：单烯烃与环烷烃；二烯烃、炔烃与环烯烃；醇和醚；酚与芳香醇或芳香醚；醛与酮；羧酸与酯；硝基化合物与氨基酸；葡萄糖与果糖；蔗糖与麦芽糖等.
例⒈写出C4H8O2的各种同分异构体（要求分子中只含一个官能团）.
【解析】根据题意,C4H8O2应代表羧酸和酯,其中羧酸（即C3H7COOH）的种类等于—C3H7的种类,故有
酯必须满足RCOOR′（R′只能为烃基,不能为氢原子）,R与R′应共含3个碳原子,可能为：
C2—COO—C：
C—COO—C2：
H—COO—C3：
【练习】已知CH3COOCH2C6H5有多种同分异构体,请写出其含有酯基和一取代苯结构的所有同分异构体.
三、由分子式分析结构特征
在烃及其含氧衍生物的分子式中必然含有这样的信息：该有机物的不饱和度.利用不饱和度来解答这类题目往往要快捷、容易得多.下面先介绍一下不饱和度的概念：
设有机物分子中碳原子数为n,当氢原子数等于2n+2时,该有机物是饱和的,小于2n+2时为不饱和的,每少两个氢原子就认为该有机物分子的不饱和度为1.分子中每产生一个C=C或C=O或每形成一个环,就会产生一个不饱和度,每形成一个C≡C,就会产生两个不饱和度,每形成一个苯环就会产生4 个不饱和度.
例⒉烃A和烃B的分子式分别为C1134H1146和C1398H1278,B的结构跟A相似,但分子中多了一些结构为的结构单元.则B分子比A分子多了33 个这样的结构单元.
四、书写同分异构体的方法
书写同分异构体时,关键在于书写的有序性和规律性.
例⒊写出分子式为C7H16的所有有机物的结构简式.
【解析】经判断,C7H16为烷烃
第一步,写出最长碳链：
第二步,去掉最长碳链中一个碳原子作为支链,余下碳原子作为主链,依次找出支链在主链中的可能位置（以下相似）
第三步,去掉最长碳链中的两个碳原子,⑴作为两个支链（两个甲基）：
①分别连在两个不同碳原子上
②分别连在同一个碳原子上
⑵作为一个支链（乙基）
第四步,去掉最长碳链中的三个碳原子,⑴作为三个支链（三个甲基）
⑵作为两个支链（一个甲基和一个乙基）：不能产生新的同分异构体.
最后用氢原子补足碳原子的四个价键.
例⒋写出分子式为C5H10的同分异构体.
【解析】在书写含官能团的同分异构体时,通常可按官能团位置异构→碳链异构→官能团异类异构的顺序书写,也可按其它顺序书写,但不管按哪种顺序书写,都应注意有序思考,防止漏写或重写.
⑴按官能团位置异构书写：
⑵按碳链异构书写：
⑶再按异类异构书写：
五、“等效氢法”推断同分异构体的数目
判断烃的一元取代物同分异构体的数目的关键在于找出“等效氢原子”的数目.“等效氢原子”是指：①同一碳原子上的氢原子是等效的；②同一碳原子所连甲基上的氢原子是等效的；③处于镜面对称位置上的氢原子是等效的（相当于平面成像时,物与像的关系）.
例⒌进行一氯取代反应后,只能生成三种沸点不同的产物的烷烃是（D）
（A）(CH3)2CHCH2CH2CH3（B）(CH3CH2)2CHCH3
（C）(CH3)2CHCH (CH3)2 （D）(CH3)3CCH2CH3
六、同分异构体的识别与判断
识别与判断同分异构体的关键在于找出分子结构的对称性,在观察分子结构时还要注意分子的空间构型.
例⒍下列事实能够证明甲烷分子是正四面体结构,而不是平面正方形结构的是（B）
（A）CH3Cl不存在同分异构体 （B）CH2Cl2不存在同分异构体
（C）CHCl3不存在同分异构体 （D）CH4是非极性分子
例⒎下列事实能说明苯分子的平面正六边形结构中碳碳键不是以单双键交替排列的是（C）
（A）苯的一元取代物没有同分异构体 （B）苯的间位二元取代物只有一种
（C）苯的邻位二元取代物只有一种 （D）苯的对位二元取代物只有一种
例⒏萘分子的结构式可以表示为或,二者是等同的.苯并(a) 芘是强致癌物质（存在于烟囱灰、煤焦油、燃烧烟草的烟雾和内燃机的尾气中）.它的分子由五个苯环并合而成,其结构式可以表示为（Ⅰ）式或（Ⅱ）式,这两者也是等同的.
（Ⅰ）（Ⅱ） （A）（B）（C）（D）
现有结构式A～D,其中
⑴跟（Ⅰ）、（Ⅱ）式等同的结构式是（A、D）
⑵跟（Ⅰ）、（Ⅱ）式是同分异构体的是（B）

BC最短当然是2了,直角三角形斜边上的中线等于斜边的一半,你可以任意做一个直角三角形然后做斜边上的中线和斜边上的高线,应为高线是垂直于斜边的,所以高线必定≤中线,所以中线最小就等于1.斜边最小等于2

The Importance of Confidence
Whatever one does, one should do it with confidence. If one has no confidence, there is little possibility that one can achieve anything when faced with hardships. This truth seems to be self-evident. In reality, however, we do see a lot of people who always complain that they lack the ability to do something or that their difficulties are too great to overcome. For some, this might be true. But for many others, this only shows that they have lost heart. Why do some people often feel frustrated even though they are capable of doing something? In the first place, these people don’t have a correct estimate of themselves. Secondly, there is another possibility that they exaggerate the difficulties.
-------------------------------------------------
Smoking
It is almost known to all that smoking is bad for people's health.The World Health Organization says diseases linked to smoking kill at least two million five-hundred-thousand persons each year.It is difficult to stop smoking.It usually becomes a habitual behaviour,are not easy to be given up.
Measures have been taken to help people keep away from the harm of smoking.The World "No Tobacco Day" is observed every year as the biggest compaign against smoking.
-------------------------------------------------
Advantages of Five-Day week
A five-day week has been put into practice in China, which is welcomed by every-one.Families have benefited from it very much. Children are able to learn usefully skills, women have enough time to take care of the house or relax.
society has also benefited from it.Then the shops and travel agency will have more customers.What's more, individuals can make full use of a weekend for a good rest. Adequate rest will enable him to work more efficiently.
-------------------------------------------------
Global Shortage of Fresh Water
People often think that water will never be used up. It seems as if water is always available around us .
In fact water is rather limited on the earth. With the rapid increase of population and fast development of industries, water is more needed than before. some big cities in China are facing the problem of water shorage already.
The people should be made aware of the real situation about the water We have to protect the existing water resources and develop new ones.
heavy shoolwork【课业繁重】
In my opinion, the schoolwork now being assigned to high school students is too heavy. While it is true that students need to study, they need other things as well if they are to grow into healthy and well-rounded adults. High should be allowed more time for play. Plying is not wasting time, as some think. It gives them physical exercise, and also exercise their imagination. Which tends to be stifled by too much study. Finally, the pressure put on high school students by excessive schoolwork can cause serious stress, which is unhealthy physically and mentally. I do not advocate the elimination of schoolwork. I do think, however, that a reduction of the current heavy load would be beneficial to students and to the society as a whole.
我认为目前高中生的课业实在太重了,虽然说学生的确应当念书,但是要想长大成为健全的人,他门还需要一些其它的东西,所以应该给高中生较多从事娱乐的时间.娱乐并不如某些人所想的,是在浪费时间,它可以让学生锻炼身体,发挥被繁重课业扼杀的想象力.此外,繁重的课业加诸在高中生身上的压力可能引起严重的情绪紧张,这对身心都有害.我并非主张废除学校课业,但是我认为减轻目前繁重的课业对于学生和整个社会都是有益的.
3．Time【时间】
Lost time is never found again. This is something which I learned very clearly last semester. I spent so much time fooling around that my grades began to suffer. I finally realized that something had to be done. It was time for a change.
Now I have a new plan for using my time wisely. I have set my alarm clock ahead half an hour. This will give me a head start on the day. I have also decided to keep a log of what I do and when I do it. Looking back on what I’ve done will give me some ideas on how to reorganize my time.
时光一去不复返,这是我上学期清楚学到的教训.我浪费很多时间四处游荡,以致于我的成绩开始退步.最后我终于了解到我必须有所作为；该是痛改前非的时候了.
现在我有一个明智运用时间的新方法.我已将闹钟早拨半小时,这将使我这一天的作息提前开始.我也决定将我所做的一切及做这些事的时间记录下来.回顾我所做的事情会启发我如何重新安排我的时间.
4．Work and Play【工作与娱乐】
Work and play do not contradict each other; in fact, they complement each other. As the saying goes, "All work and no play makes Jack a dull boy." A life burdened with work leads you nowhere, for you would get tired and bored with your daily routine work. On the other hand, proper recreation will relieve the tension and discomfort of our monotonous life because it offers you various ways to let out your pent-up emotions.
What I usually do to relax after school is jogging and seeing movies. Usually I don't spare time for exercise, but I value the physical education class at school. Jogging several rounds in the field certainly relieves the day's pressure. On weekends, I'll catch the morning movie for my visual enjoyment. I feel revived and energetic for another week's work-load.
工作与娱乐并不互相冲突,事实上,它们之间的关系还相辅相成.有句格言说：「整日工作而没有休闲娱乐,会令人变得沉闷乏味.」被工作重担压得喘不过气来的生活,将使你一事无成,因为你将对一成不变的例行公事感到厌烦.由另一方面来说,适度的娱乐活动能提供各种管道,来渲泄你被压抑的情绪,减轻单调生活中的紧张与不悦.
放学之后,我最常做的休闲活动,便是慢跑与看电影.通常我并不特地拨出时间来做运动,但是我很重视学校的体育课.在操场上慢跑几圈,无疑地可以减轻一天的压力.在周末时,我都去看早场电影,享受视觉飨宴.如此一来,我将有如再生般的充沛活力,去面对下一星期的工作量.
5．My first Job【我的第一份工作】
My first job was at a cramming school. It was three years ago when I just graduated from junior high school and finished the entrance examination. since I had nothing to do that summer, I decided to find a job, tasting the joy of independence.
I was responsible for answering the telephone and taking the message. I worked eight hours a day, six days a week. The work was not difficult nor heavy to me and I guess I did well. The most delighted thing was perhaps that I could spend the money I earned all by myself.
我的第一份工作是在一家补习班做事.那是三年前我刚从国中毕业,考完联考时的事了.既然我那整个夏天都闲着没事,倒不如找份差事,尝尝独立赚钱的快乐.
我负责接听电话且纪录留言的工作.我一天工作八小时,一星期工作六天.那份工作对我而言既不困难亦不沉重,所以我想我还满称职的.而最令人快乐的事大概莫过于花全部由自己赚来的钱了!
6．My Favorite Sports【我最喜爱的运动】
Sports help everyone to keep healthy, happy, and efficient. So I pay special attention to games, especially table-tennis. Table tennis is my favorite game. I play it almost every day.
Table-tennis is an ideal game us because it brings the whole body into action. It strengthens our muscles, expands our lungs, promotes the circulation of the blood, and causes a healthy action of the skin. Besides, it is very amusing and does not cost us much money. Table-tennis is very moderate; it is not so rough as football. It is an indoor game and can be played even on rainy days. Thus, it is my favorite kind of exercise.
运动能帮助每一个人保持健康、快乐和有效率.所以我特别重视运动,特别是桌球,桌球是我最喜欢的运动.我几乎每天玩.
桌球对我们而言,是一项理想的运动,因为它可以使我们全身运动,它可以增强我们的肌肉,扩张我们的肺部,促进血液循环,并且使肌肤产生健康作用,此外,它很有趣而且所费不多.桌球是相当温和适中的,它不像足球那么粗野.它是一种室内运动,甚至在下雨天也能玩.因此,桌球是我最喜爱的一种运动.
希望能对你有所帮助～～：）

晓出净慈寺送林子方[宋]·杨万里
毕竟西湖六月中,风光不与四时同.
接天莲叶无穷碧,映日荷花别样红.
古诗今译】
毕竟是西湖六月天的景色,
风光与其他季节确实不同.
莲叶接天望不尽一片碧绿,
阳光下荷花分外艳丽鲜红.
【赏析】
西湖美景历来是文人墨客描绘的对象,杨万里的这首以其独特的手法流传千古,值得细细品味.“毕竟西湖六月中,风光不与四时同”,首句看似突兀,实际造句大气,虽然读者还不曾从诗中领略到西湖美景,但已能从诗人赞叹的语气中感受到了.这一句似脱口而出,是大惊大喜之余最直观的感受,因而更强化了西湖之美.果然,“接天莲叶无穷碧,映日荷花别样红”,诗人用一“碧”一“红”突出了莲叶和荷花给人的视觉带来的强烈的冲击力,莲叶无边无际仿佛与天宇相接,气象宏大,既写出莲叶之无际,又渲染了天地之壮阔,具有极其丰富的空间造型感.“映日”与“荷花” 相衬,又使整幅画面绚烂生动.全诗明白晓畅,过人之处就在于先写感受,再叙实景,从而造成一种先虚后实的效果,读过之后,确实能感受到六月西湖“不与四时同”的美丽风光.
饮湖上初晴后雨[宋]·苏轼
水光潋滟睛方好,山色空蒙雨亦奇.
欲把西湖比西子,淡妆浓抹总相宜
译文
一天,苏轼和朋友在西湖边上饮酒.开始天气晴朗朗的,不大工夫竟阴了天,下起雨来.这样,饮酒未尽,诗人便饱览了西湖上晴和雨两种截然不同的风光.于是诗人赞叹说：晴天的西湖,水上波光荡漾,闪烁耀眼,正好展示着那美丽的风貌；雨天的西湖,山中云雾朦胧,缥缥渺渺,又显出别一番奇妙景致.我想,最好把西湖比作西子,空蒙山色是她淡雅的妆饰,潋滟水光是她浓艳的粉脂,不管她怎样打扮,总能很好地烘托出天生丽质和迷人的神韵.
简析
这是一首赞美西湖美景的诗,写于诗人任杭州通判期间.原作有两首,这是第二首.
首句“水光潋滟晴方好”描写西湖晴天的水光：在灿烂的阳光照耀下,西湖水波荡漾,波光闪闪,十分美丽.次句“山色空蒙雨亦奇”描写雨天的山色：在雨幕笼罩下,西湖周围的群山,迷迷茫茫,若有若无,非常奇妙.从题目可以得知,这一天诗人在西湖游宴,起初阳光明丽,后来下起了雨.在善于领略自然美景的诗人眼中,西湖的晴姿雨态都是美好奇妙的.“晴方好”“雨亦奇”,是诗人对西湖美景的赞誉.
“欲把西湖比西子,浓妆淡抹总相宜”两句,诗人用一个奇妙而又贴切的比喻,写出了西湖的神韵.诗人之所以拿西施来比西湖,不仅是因为二者同在越地,同有一个“西”字,同样具有婀娜多姿的阴柔之美,更主要的是她们都具有天然美的姿质,不用借助外物,不必依靠人为的修饰,随时都能展现美的风致.西施无论浓施粉黛还是淡描娥眉,总是风姿绰约的；西湖不管晴姿雨态还是花朝月夕,都美妙无比,令人神往.这个比喻得到后世的公认,从此,“西子湖”就成了西湖的别称.
