满意加到200分.两张都是一样的,可能有些不清晰,要写出过程,能做多少就做多少.

北京一带气候寒冷,过了花朝节,残留的寒意仍然很凛冽,冷风时常刮起,一刮冷风就扬起满天沙尘.我只好拘束在屋子里,想出去走走也不行.每次迎着风快步疾走出去,不到百步就转了回来.
二月二十二日那天,略微暖和些,我和几个朋友一块儿出了东直门,到了满井,高大的柳树成排的分立在堤的两旁,肥沃的土地有些湿润.放眼望去是一片开阔的景象,好像是自己从笼子里飞出来的天鹅无比轻松.这时河上的冰开始融化,水波开始发出亮光,泛起一层一层鱼鳞似的波纹,水清澈极了,可以看到河底,亮晶晶的,好像刚打开镜匣,冷光突然从匣子里闪射出来一样.山峦被融化的雪水洗过后,是那样美好、光洁,呈现出迷人的风姿,好像美丽的少女洗了脸刚刚梳好髻鬟一样.柳条将要伸展却尚未伸展,柔嫩的梢头在风中散开,麦苗出土了,高一寸左右.游人还不算很多,但汲泉煮茶喝的,拿着酒杯唱歌的,身着艳装骑驴的,也时时可以见到.风力虽然还很猛,然而徒步行走就会有汗水流出湿透脊背.所有在沙滩上晒太阳的鸟儿,浮到水面上吸水的鱼,都是一副悠闲自在的情态,一切动物当中都充满了欢乐的气氛.我这才知道郊田外面未尝没有春天,可住在城里的人却不知道啊.
能够不因为游山玩水而耽误正事,潇洒地徜徉於山石草木之间,就只有我这种闲官.而满井这地方刚好离我的居所近,我游山玩水将从这个地方开始,又怎能没有记录的文章呢!乙亥年二月.

Where can I encountered seven Aberdeen (full text)
(A)
In the process of growth,we will encounter a lot of things,if it is happy not to Deyiwangxing,or getting too much; if it is painful,do not complain,because it will be the others will never be able to take the post of your wealth.
Is that your wealth - there are always older predecessors instill this concept to me.
I was smiling by Dian Zhuotou land,but in his heart whispered to Ma Zhao,"You have to feel so good,I left all the wealth of hello."
In any case,not of wealth.
(B)
Impression can recall,there are so few things that I always remind myself that we must forget,as nothing happened,my life had not been made,said the impact of.
They have been directly or indirectly,changed my track to grow.
(C)
On one occasion.In the approach of test results at the upper and middle reaches of the table after I asked math questions,teachers did not know where to jump up,angrily said:"Wang Moumou a good review,Do not waste valuable time on him."
59 students in his class,59 pairs of eyes stare back together.I will never forget that moment for all,Fangruo nailed me,the sadness,pity,ridicule and something more to say,watch the eyes ....
The humiliation did not play a lot of stories inside of the scenes are bound to happen - the main character has been in a lot of humiliation after the beginning of the high level,the extraordinary final play,cum laude admitted to a well-known schools,the snow was to shame ......
I do not have such a great talent.At the time,I,weary,partial Branch,sensitive and low self-esteem.In addition to Yin Ren at the time of tears,pretend nothing happened,cried a home run,draw any change in their status and fate of the move.
After I began to give up on themselves,then naturally the focus has not admitted to any school.I have to admit that Wang Moumou was indeed a waste of time.I can not say any words of rebuttal.Only to see the "teacher" words will be frowned,smiled and far-fetched.
(D)
There are many such things.For example,when Gao witnessed his best friend was mistaken diagnosis and treatment of a doctor to die; the holidays to find their first job,but that's Pianqian ......
There's.
Perhaps there will be no more.
I also may be forgotten.
These injuries have been deeply in the India head,engraved in mind.With the inter-year-old goes on,like a washed up by many times the clothes were constantly depreciation,increasing yellowing.
(E)
On the very back teeth bite?Strong enough to solve all?It was given a powerful force,it has a strong spiritual support - not the fact.
Just because it can not go back.
(F)
Character often say the fate of the decision.I think this is probably true,at least on the fate of the play can change a lot of impact,right?
If I was able to work hard,perhaps on the Hong Kong Certificate of Education a good school,right?
Had never experienced the death of a friend,I would not be suffering from neurasthenia,right?
Had the company not to be Pian Qian,I may often exercise their own labor,right?
............
濡傛灉.濡傛灉.濡傛灉.濡傛灉.
So,"if" - will not be a Chinese dictionary,you were one of the most frequently used word this?Because carrying too much hope,and never regret,the frequency of use by more than repeated.
But ...
If,after all.
(G)
"On the 7th of the Yangtze",the nagging Xingye over to the small Di said:Although we are poor,but can not lie,can not be beat; is not our thing,we can not hold; to study hard,to be brought up on Useful to the community.Di small that no father to rescue them,old and broken lying on the bed with his arms crying,thinking up these ideas are:If not encountered seven small Di-earners,it will be like now?If we went back to a similar Xingye,or seven-earners,no matter what is the best teacher is also the Friends of the guy,we make the following allegiance to the cloth,then perhaps all will be different,right?
Not to enlarge the pain of youth.Do not look for trouble.
Non-inferiority.No impulse.Fuqi not.
Others do not because of their own to stimulate change.
Do not always look forward to other people "understanding" of their own.Maybe some people will understand,but you may not be really concerned.
Others say,praise or abuse worth,heard passed,no room for complacency,no need for a more tears.
In the absence of verification in person before,do not believe anyone would say.Including your teachers,your parents,but also your classmates and friends.
Some people call you,your friends to call you if you are convey to the - this person is not a true friend.
Regardless of what parents say and do anything,to believe that they will not harm you.If so,they must be the way a problem.
Finally,please take good care of yourself.
(H)
Today - I still do not believe that wealth is gone.
However,I believe,so every time a different choice,we must stand ready to suffer as a result of the choices arising from the cost and pain.
For the young to pay the price.More ignorance and impulse pay the price.
You imprison the youth and superior,after all,to use an adult's hard to make up and go.

小朋友,自己要努力学习!

设这个多边形的边数是n,它的内角和为180（n-2）,则从100到140共有n个角,
（100+140）n/2=180(n-2)
解得n=6
所以这个多边形的内角和为720°

我的家乡在素有“左脚舞之乡”的牟定,它坐落在化佛山脚下,是一个美丽的小县城,作文 家乡的变化.x09　x09
　　大千世界,每时每刻都在发生着变化,我的家乡也不例外.近几年来,我亲眼目睹了家乡环境可喜的变化.x09　x09
　　原来的县城街道非常狭窄,周围没有垃圾箱,人们总习惯把垃圾随手扔在地上,所以,只要风一吹,尘土和垃圾就会满天飞舞.狭窄的街道两旁只有几棵小树,仅有的这几棵树还长得弯弯曲曲,树叶也是稀稀疏疏,上面还沾满了灰尘.x09　x09
　　原来公园的环境还比软好,可人们不懂得爱护环境,吃完东西随便乱扔在地上和水里,久而久之,地上堆满了垃圾、水变得绿蒙蒙的,人们走到这儿的时候,都要捂着鼻子匆匆而过.x09　x09
　　从前的化湖被称作“校场坝”,是一个很大的坝塘,周围长满了杂草、扔满了垃圾、旁边小沟里的水黑黑的,有的人居然还在坝塘边杀牛,牛骨扔了到处都是,牛血也淌了一地,从一旁经过臭气熏天,苍蝇在天空中到处乱飞.
　　随着人们经济水平的提高和环保意识的增强,我家乡的环境也发生了翻天覆地的变化,不信你看：x09　x09
　　现在的县城街道变得非常宽阔,周围摆放了一些垃圾箱,人们也不再乱扔垃圾了,街道变得非常干净、整洁,周围的绿化变得郁郁匆匆,长得非常茂盛.x09　x09
　　现在的公园和以前的那个公园已经大不一样了,里面种上了亭亭玉立的柳树,小河变得清澈见底,草地像一块绿地毯,是人们休闲娱乐的好去处.x09　x09
　　现在的化湖已经找不到当年“校场坝”的一点儿影子了,那里鸟语花香、绿树成荫,人们都喜欢三五成群的到这儿游玩、散步.x09　x09
　　啊!在这几年中,家乡的变化真大呀,大树变多了,变绿了,空气变得更纯净了,溪水变得更清澈了.群山环抱、绿水相依,构成了一幅家乡精美的画卷,作为一名牟定人,怎能不为此感到骄傲和自豪呢!x09

n:
the next day,there was a story in the newspaper.a motorcycle had crashed into a building because its brakes were broken.
there were two people on the motorcycle,of which one died,and the other had survived...

每天你都有机会和很多人擦肩而过,或者你对他们一无所知,不过某天他会变成你的朋友或知已.是的,人海茫茫,相识是缘,相知更是前世修,让我们朋友越来越多,生活越来越好……

“写出的作文总是不能令自己满意,看过的一些课外资料一到考场上就想不起来了,不能灵活运用.”
写出的作文总不能令自己满意
问题分析：
1.辞不达意,写出的文章不能很好地表达自己的想法
2.不知道怎样写,写出来自己都不知道表达了什么东西
对策：
1.多练笔.辞不达意,是因为平时写得少,不会表达.练笔不等于写作文,只是作为随笔,平时有意识地写写对身边的人和事对热点新闻的看法,训练自己的思维能力.练笔也可以写写提纲,找一本高考作文审题类的书,自己用高考题做审题,写出提纲,提纲内容包括观点、分论点、论据,甚至可以包括开头和结尾.写提纲是一种很好的提高方法,可以从审题、结构、论据等方面得到提高.
2.多看时评,看看别人对一个问题的评论是从什么角度切入的,又是怎样论述的.特别是一些热点时评,见仁见智,有各种不同的观点,是很好的学习材料.只有学习怎样去思考问题,又怎样表达出来,你才能写好作文.
看过的一些课外资料一到考场上就想不起来了,不能灵活运用.
问题分析：
素材只是看过而已,没有做积累工作,边看边忘.有不少人认为,平时多看看书,就能提高作文能力了.却不知道该看什么书,怎样看书才有用.
对策：
做好素材积累,拥有你自己的素材!看到一些课外资料,要有意识地抄录下来.可以用人物身份分类,如科学家、文学家、新闻热点人物……然后在人物或故事后面写写你的思考：该人物（故事）可用于什么话题什么观点.
什么才是自己的素材呢?如姚明是家喻户晓的人物,但你如果积累了他说过的一句话,一个训练的细节,这就是你才拥有的素材了.如有些人物大名鼎鼎,却不为同学们所熟知的,好像苏格拉底之类的,也可以积累他的名言与事迹作为你自己的素材.作文里用上自己的素材能令阅卷老师眼前一亮,提高作文得分.
写作文和考试之前,翻翻你自己的素材积累本,再到写作文的时候就胸有成竹了.
希望以上回答能帮上忙!

大陆架：大陆架是大陆向海洋的自然延伸,通常被认为是陆地的一部分.又叫“陆棚”或“大陆浅滩”.它是指环绕大陆的浅海地带等高线比较疏.大陆坡： 向海一侧,从陆架外缘较陡地下降到深海底的斜坡.它展布于所有大陆周缘,为全球性地形单元.等高线比较密.

如果要写好作文的话,有五方面一：提高认识事物和表达事物的能力.我国著名教育家叶圣陶先生指出：“写任何东西决定于认识和经验,有什么样的认识和经验,才能写出什么样的东西来.反之,没有表达认识的能力,同样也写不出好作文”.
　　二、把认识结构作为作文的核心,包括学习知识,观察积累,记忆储存,训练思维,丰富想象,培养情感,锻炼意志；从说到写,推敲修改,多读勤写.
　　三、树立大作文观,听、说、读、写有机结合
　　一要注重审题；二要明确写作目的,立意要新；三是选材要有根据；四要讲究谋篇技巧,安排好篇章结构；五要注意文章分段,事先列小标题,作文提纲；六要注重文章写法,因文用法；七要妙用语言,用思想调遣语言.
　　学会五种立意法：以事赞人,直抒胸臆,借物喻理,触景生情,托物言志.
　　四、作文大目标的逐年级分一年级字词,二年级句子,三年级片断,四年级篇章,五年级综合,六年级提高.
　　五、实施五项训练
　　根据认识是作文的核心这一原则,围绕这个发展学生心理机制的核心,扎扎实实地进行了五项训练：
　　（一）、字词训练.学习掌握大量字词.掌握运用字词的金钥匙：联系自己熟悉的事物；联系自己生活实际；联系自己学会的语言及字词知识.
　　运用“十引说”的方法,把字词学习与说话训练相结合.“十引说”是：1、分析字形；2、利用教具；3、凭图学词；4、组词扩词；5、选词填空；6、词语搭配；7、调整词序；8、触景用词；9、词语分类；10、联词成句.丰富了说话训练内容,使自己积累大量会说会用的字词,为写作文打下坚实基础.
　　（二）、句子训练.只要是一个句子,都包括两个方面：一是说的人、事、物、景,二是说目的.可有些教师指导学生说一句话时,没有很好凭借图画和事物,认真教学生观察、认识、分析、表达的方法,只是拿出一张图或一事物让学生说写一句话,学生不知道为什么要说写一句话,怎样说写一句话,说写一句什么句型、什么句式的话,导致作文中语调单一、呆板、不活泼生动.可以改让学生凭图、看物、对话、练习说写一句时间、地点、人物、事件四要素完整的话,四种句型,九种句式的话.学生才会在作文中运用不同句型、句式,表达不同的思想、感情、态度、目的.
　　（三）、段的训练.结合八种段式：以事物发展为序段,时间先后为序段,空间变换为序段,总述、分述结构段,因果段、转折段,递进段,并列段.以此认识客观事物的发生、发展规律.不论哪种段式,都是记叙事物的发展和人们对事物的认识,即段的内容,段的中心.它和一句话一样,也是对人、事、物、景的叙述,也是表达一个意思.只不过是把一句话进一步说得更清楚、更深刻.
　　（四）、篇章训练.篇是由段组成的.通过对审题、立意、选材、谋篇、定法、用语的知识与方法,通过记叙、描写、抒情、议论四种表达方法,文章开头与结尾、过渡与呼应方法,各种文章体裁的知识与方法.学会写中心明确,意思完整,详略得当的记叙文和应用文.
　　（五）、生活现场训练.采用生活现场训练,更好地体会“从内容入手”写作文.通过各种作文教学活动,如“确定中心讨论会”、“选材讨论会”、“作文会诊会”、“小诸葛审题会”、“妙用词语比赛会”,从活动中生动具体地学到作文知识与写作文的方法.另外,还可开展各种校内外活动,如跳绳、拔河、踢毽、球类、背书比赛,从而学会如何写比赛作文；开展校内外义务劳动,学会如何写劳动场面；举行诗歌朗诵、讲演会,学会如何写会议场面及会议上的见闻；通过参观访问,浏览名胜古迹,学会如何写参观访问记、游记.学习观察方法,留心周围的事物、事件,“处处留心皆学问,人情练达即文章”.通过现场生活作文,进一步认识到：生活是作文的沃土.从而学会写真事、抒真情,陶冶真、善、美的情操,培养良好的文风.
还要多看作文书,看看别人怎么写,把好的句子记一下.

1.一天中制衣所获得的利润是（5a×20＝100a ）；
2.一天中剩余布所获得的利润是[20（100-a）-2×5×a]×2=4000-60a
3.要使一天 所获得的利润为6640 元,应安排多少名工人制衣,多少名工人织布?
设应安排a名工人制衣,100－a名工人织布
100a+4000-60a＝6640
40a+4000=6640
40a=2640
a=2640÷40
a＝66 即66名工人制衣
100－a＝100-66=34名工人织布
