星期天小明和小慧到德州开发区减河湿地去玩他们才叫阮越山上留下一串脚印小明突发奇想的小会说我的体重是五十千克

解题思路：要想知道小明买瓜有没有吃亏，就要求出最小瓜的重量，然后用10千克减去最小瓜的重量，即可求出剩余瓜的重量，然后与0.7×10=7元能买多少瓜进行比较．

8+7+5=20，
剩余瓜的重量：
10-10×[5/20]，
=10-2.5，
=7.5（千克）；
原来应买西瓜：
0.7×10÷1=7（千克）；
因为7.5＞7，所以没有吃亏．
答：小明买瓜有没有吃亏

点评：
本题考点： 按比例分配应用题．

考点点评： 此题再求最小瓜的重量时，运用了按比例分配的方法．

张老师是根据篮子的重量差求出来的：篮子在此摊主的称上重0.275kg,与实际重量的差是0.025kg(0.275-0.25=0.025),所以由比例得 0.025：0.25=少称的鸡蛋重量：5,口算得少称的鸡蛋数量为0.5kg.
启发：巧妙地将数学应用到生活中,解决小小问题得心应手

解题思路：车费应分为两部分，一部分是在4千米内；一部分超过4千米的部分，即（29-5）÷1.5=16（千米）；然后把这两部分加起来即可．

（29-5）÷1.5+4，
=16+4，
=20（千米）；
答：小明家到爷爷奶奶家有20千米．

加油吧!

你想想作业做不完的后果.我们都是赶作业的人,你试着不想那么多事,心平气和地做作业,现在也少上网,不然你的脑子会感到很乱很乱,只要用心去专注作业就可以了!不然你摆着作业不做而上网的话,你心里会觉得很迷茫,有种危机感,快点写作业吧.分神也好专注也好,总比不做要好!

解题思路：本题可列方程解答，设原来有x个苹果，吃了全部的[5/9]少3个后，则还剩下（1-[5/9]）x+3个，妈妈回家时，又带回来31个，结果现在的苹果数比吃以前的个数还多20%，即此时的个数是原来的1+20%，为（1+20%）x个，由此可得方程：（1-[5/9]）x+3+31=（1+20%）x．

设原来有x个苹果，可得方程：
（1-[5/9]）x+3+31=（1+20%）x．
[4/9]x+34=120%x，
[34/45]x=34，
x=45．
答：原来有45个．

点评：
本题考点： 分数和百分数应用题（多重条件）．

考点点评： 通过设未知数，根据所给条条件列出方程是完成本题的关键．

30朵
他如果买了花就超过了 300元,
就会打 8折
而营养品打八折要 300×0.8=240
所以差一些钱才到 300
所以还有 300-240=60元 卖花
所以 60÷(2.5×0.8)=30
所以再买 30 朵花刚好只花了 300元
比较简略,自己琢磨琢磨吧

他长得矮小粗壮,身板结实硬朗,一张土红色的狮子脸上额头高高地突起.乌黑浓密的头发虬结在头顶,似乎梳子都难以将厚实的头发梳通.他的双眸具有强烈的震慑力,放射出粗野狂放的光芒.蓝灰色的眼珠往往会因兴奋或愤怒而张得很大,在眼眶里转个不停,而眼珠大多数时候都将他内心的忧愁展露无遗.有朋友说他笑起来很甜美,带着鼓舞人的神情,然而他是一个不习惯欢乐的人,他平时的表情很忧郁,仿佛内心里有无法排遣的忧伤.当朋友看到他沉浸在痛苦中时,需要竭尽全力才能忍住眼泪.一次,一个朋友在一家小酒店里喝酒,他正坐在角落里,紧闭双目,抽着烟斗,仿佛静静地等待死神的降临.朋友与他寒暄两句,他凄惨地一笑,从口袋里掏出一个本子,用聋子常有的尖叫让对方写下他要说的话.他的脸色经常会变化,面部肌肉隆起,青筋暴露,眼露凶光,嘴唇抖个不停.这副可怕的表情往往会将别人吓得灵魂出窍.这是因为他创作灵感突然出现了,或是他弹琴弹得太投入了,进入了忘我的境界.

“叫什么？叫什么！星期天都不让我好好睡一觉。”我说。“你忘了吗？今天还要去学国画。”外婆说。“再睡会，再睡会。”我又说。“睡什么睡？”外婆那如大喇叭似的声音终于把我吵醒了，我迷迷糊糊的起了床。“唉！为什么周末都有外婆这个“大喇叭”的吼叫声呢？”我说。没办法，谁叫我每个星期都要去学国画呢？我穿好衣服，路过爸爸妈妈的卧室，“哟！你们睡的真香，等我当上了爸爸，我也要像你们一样，周末睡个够。”我自言自语的说。
吃过早餐后，我马上就去艺术宫画画去了，熬过两个小时的画画时间，我想：老爸老妈该起床了吧。我回家一看，老妈已经起床了，老爸居然还没起床。我对着老爸大声的说：“大懒虫你快快起来。”这句话我重复了许多遍后，嘴巴都冒烟了，老爸才起来。老爸起床后，为了让他弥补他的过错，我们决定让老爸做午饭。从老爸的表情可以看出他不想做，可没办法，谁叫他睡懒觉呢！吃完午饭后，我在玩具室里玩玩具，老爸老妈偷偷的出去打麻将了，我高兴极了，爸妈不在家，外婆在睡觉，这可是个好机会，我飞快的下了楼和小朋友们打了乒乓球、比赛了自行车，疯狂的玩了一下午。
老爸老妈回家后问我：“今天过得高兴吗？”我偷笑着说：“这个星期天我太高兴，太愉快了！”

Friends to call at three in the afternoon,evening come to my house for dinner.I said,"well,of course,a meeting." Say "good,a meeting" is good manners.But my heart still feel a bit strange.It's not that I don't wish to see the friend,I don't want to please him not eat.But as this is the first time someone said to come to my house for dinner.
With the friend in Beijing,they say this is very normal.And said to them,go into ChuanMenZi childhood friend home to eat,and other people in home even a specially dedicated to his order.Look at their expression,I know,when not invited guest not only,still happy memories of their childhood.
When I was a kid to play in the neighbor is often eat,but I remember only once.Because I was ill,and mother to work,so she lets me a little neighbor cooked porridge.Neighbor:let me use cookies to send porridge.Cookies are foreign goods,neighbor is polite to let me use cookies,but after that send porridge,I would love to eat cookies.Because it's white bread PeiQu porridge yucky.
At school,my friends study is very busy,also did not say to the house.All is in a restaurant.Until everyone had a holiday,began to ask a friend to come home to play and eat.Chinese restaurant and expensive and not good,otherwise will continue to meet friends in the outside.Because of my life without the other people's traditional,no others say his friend,so say to come to dinner really makes me feel strange.
This reminds me of the "polite" and "normal" regional exchanges.The traffic here is not outside also can accept.HSBC Hong Kong "wherever I are local Banks to flaunt".It is an advertisement,said a local rules are a young lady of Italy,he took a bunch of chrysanthemum in her door,but don't know in Italy is used in funeral chrysanthemum.Miss neighbor saw Daisy thought she died,in the door on chrysanthemum.When the lady again is not only a chrysanthemum confused,put an old lady was frightened.
But I feel scared the little old lady jump or friends,have a misunderstanding is worth.Know a young man,exchanged phone,he added:"I find you play." I can't catch her face,must be a young man didn't expect the expression,I just feel atmosphere suddenly wrong.Young people are not again after contact with me.He could feel the people I how so crazy,1 kind words are not,let him uncomfortable.Then think about is not a polite?!I said,he often does not really want to come to my house to play.This is he said kind words,but I didn't answer his kindness.But when I was a reaction,how to just know he himself said to my house?But I still warm reception and dinner we gave him in the table with interesting topics,occasionally also laughed.
I still feel strange at first,but now the atmosphere is good,eat a meal together to talk,play CARDS,ha ha,with friend together are very interesting.

是五年级的吧.

昆明有个圆通寺.寺后就是圆通山.从前是一座荒山,现在是一个公园,就叫圆通公园. 公园在山上.有亭,有台,有池,有榭,有花,有树,有鸟,有兽. 后山沿路,有一大片海棠,平时枯枝瘦叶,并不惹人注意,一到三四月间,真是花团锦簇,变成一个花世界. 这几天天气特别好,花开得也正好,看花的人也就最多.“紫陌红尘拂面来,无人不道看花回”,办公室里,餐厅里,晚会上,道路上,经常听到有人问答：“你去看海棠没有?…‘我去过了.”或者说：“我正想去.”到了星期天,道路相逢,多争说圆通山海棠消息.一时之间,几乎形成一种空气,甚至是一种压力,一种诱惑,如果谁没有到圆通山看花,就好像是一大憾事,不得不挤点时间,去凑个热闹. 星期天,我们也去看花.不错,一路同去看花的人可多着哩.进了公园门,步步登山,接踵摩肩,人就更多了.向高处看,隔着密密层层的绿荫,只见一片红云,望不到边际,真是“寺门尚远花光来,漫天锦绣连云开”.这时候,什么苍松啊,翠柏啊,碧梧啊,修竹啊,……都挽不住游人.大家都一口气地攀到最高峰,淹没在海棠花的红海里.后山一条大路,两旁,四周,都是海棠.人们坐在花下,走在路上,既望不见花外的青天,也看不见花外还有别的世界.花开得正盛,来早了,还未开好,来晚了已经开败,“千朵万朵压枝低”,每棵树都炫耀自己的鼎盛时代,每一朵花都在微风中枝头上颤抖着说出自己的喜悦.“喷云吹雾花无数,一条锦绣游人路”,是的,是一条花巷,一条花街,上天下地都是花,可谓花天花地.可是,这些说法都不行,都不足以说出花的动态,“四厢花影怒于潮”,“四山花影下如潮”,还是“花潮”好.古人写诗真有他的,善于说出要害,说出花的气势.你不要乱跑,你静下来,你看那一望无际的花,“如钱塘潮夜澎湃”,有风,花在动,无风,花也潮水一般地动,在阳光照射下,每一个花瓣都有它自己的阴影,就仿佛多少波浪在大海上翻腾,你越看得出神,你就越感到这一片花潮正在向天空向四面八方伸张,好像有一种生命力在不断扩展.而且,你可以听到潮水的声音,谁知道呢,也许是花下的人语声,也许是花丛中蜜蜂嗡嗡声,也许什么地方有黄莺的歌声,还有什么地方送来看花人的琴声,歌声,笑声……,这一切交织在一起,再加上风声,天籁人籁,就如同海上午夜的潮声.大家都是来看花的,可是,这个花到底怎么看法?有人走累了,拣个最好的地方坐下来看,不一会,又感到这里不够好,也许别个地方更好吧,于是站起来,既依依不舍,又满怀向往,慢步移向别处去.多数人都在花下走来走去,这棵树下看看,好,那棵树下看看,也好,伫立在另一棵树下仔细端详一番,更好,看看,想想,再看看,再想想.有人很大方,只是驻足观赏,有人贪心重,伸手牵过一枝花来摇摇,或者干脆翘起鼻子一嗅,再嗅,甚至三嗅.“天公斗巧乃如此,令人一步千徘”.人们面对这绮丽的风光,真是徒唤奈何了. 老头儿们看花,一面看,一面自言自语,或者嘴里低吟着什么.老妈妈看花,扶着拐杖,牵着孙孙,很珍惜地折下一朵,簪在自己的发髻上.青年们穿得整整齐齐,干干净净,好像参加什么盛会,不少人已经穿上雪白的衬衫,有的甚至是绸衬衫,有的甚至已是短袖衬衫,好像夏天已经来到他们身上,东张张,西望望,既看花,又看人,洋气得很.青年妇女们,也都打扮得利利落落,很多人都穿着花衣花裙,好像要与花争妍,也有人擦了点胭脂,抹了点口红,显得很突出,可是,在这花世界里,又叫人感到无所谓了.很自然地想起了龚自珍《西郊落花歌》中说的,“如八万四千天女洗脸罢,齐向此地倾胭脂”,真也有点形容过分,反而没有真实感了.小学生们,系着漂亮的红领巾,带着弹弓来了,可是他们并没有射击,即便有鸟,也不射了,被这一片没头没脑的花惊呆了.画家们正调好了颜色对花写生,看花的人又围住了画花的,出神地看画家画花.喜欢照相的人,抱着相机跑来跑去,不知是照花,还是照人,是怕人遮了花,还是怕花遮了人,还是要选一个最好的镜头,使如花的人永远伴着最美的花.有人在花下喝茶．有人在花下弹琴有人在花下下象棋,有人在花下打桥牌.昆明四季如春,四季有花,可是不管山茶也罢,报春也罢,梅花也罢,杜鹃也罢,都没有海棠这样幸运,有这么多人．这样热热闹闹地来访它,来赏它,这样兴致勃勃地来赶这个开花的季节.还有桃花什么的,目前也还开着,在这附近,就有几树碧桃正开,“猩红鹦绿天人姿,回首天桃惝失色”,显得冷冷落落地呆在一旁,并没有谁去理睬.在这圆通山头,可以看西山和滇池,可以看平林和原野,可是这时候,大家都在看花,什么也顾不得了. 看着看着,实在也有点疲乏,找个地方坐下来休息一下吧,哪里没有人?都是人.坐在一群看花人旁边,无意中听人家谈论,猜想他们大概是哪个学校的文学教师.他们正在吟诗谈诗： 一个吟道：“泪眼问花花不语,乱红飞过秋千去.” 一个说：“这个不好,哪来的这么些眼泪!” 另一个吟道：“一片花飞减却春,风飘万点正愁人.” 又一个说：“还是不好,虽然是诗圣的佳句,也不好.” 一个青年人抢过去说：“‘繁枝容易纷纷落,嫩蕊商量细细开’,也是杜诗,好不好?” 一个人回答：“好的,好的,思想健康,说的是新陈代谢.” 一个人不等他说完就接上去：“好是好,还不如龚定庵的‘落红不是无情物,化作春泥更护花,有辩证观点,乐观精神.” 有一个人一直不说话,人家问他,他说：“天何言哉,四时兴焉,万物生焉,天何言哉.桃李无言,下自成蹊.你们看,海棠并没有说话．可是大家都被吸引来了.” 我也没有说话.想起泰山高处有人在悬崖上刻了四个大字：“予欲无言”,其实也甚是多事. 回家的路上,还是听到很多人纷纷议论. 有人说：“今年的花,比去年好,去年,比前年好,解放以前谈不到.” 有人说：“今天看花好,今夜睡梦好,明天工作好.” 有人说：“明天作文课,给学生出题目,有了办法.” 有人说：“最好早晨来看花,迎风带露的花,会更娇更美.” 有人说：“雨天来看花更好,海棠著雨胭脂透,当然不是大雨涝沱,而是斜风细雨.” 有人说：“也许月下来看花更好,将是花气氤氲.” 有人说：“下星期再来看花,再不来就完了.” 有人说：“不怕花落去,明年花更好.” 好一个“明年花更好”.我一面走着,一面听人家说着,自己也默念着这样两句话： 春光似海, 盛世如花.
