Today is a day of[with] delectation, thought to take place many worthy of happy of matter.Release from school to go home, I swept a house for mother, also wiping a shoes for father.So I am given public recognition by parents.Arrived a school in the afternoon, I picked up a little money to hand over to a teacher, the teacher gave public recognition me at the whole class classmate in front!Afterwards the mathematics teacher say I can test a whole class the first this time!Today What a happy one good heavens!

因为姐姐五年后的年龄与妹妹三年前的年龄和是29岁,所以： 29岁＝（姐姐现在年龄＋5岁）＋（妹妹现在的年龄－3岁） 姐妹俩现在的年龄和是： 29－5＋3＝27（岁） 若姐妹两人年龄差为1倍,则： 妹妹现在的年龄...

180-30-24=126（元）
126×2=252（元）
（126+252）-（180+30）=168（元）
答：一共剩下168元.

解题思路：根据题干，设弟弟有x张，则姐姐就是3x张，再利用等量关系：姐姐的张数+弟弟的张数=总张数180，据此列出方程解决问题．

设弟弟有x张，则姐姐就是3x张，根据题意可得方程：
x+3x=180
4x=180
x=45
45×3=135（张）
答：姐姐135张，弟弟45张．

点评：
本题考点： 列方程解含有两个未知数的应用题．

考点点评： 此题属于含有两个未知数的应用题，这类题用方程解答比较容易，关键是找准数量间的相等关系，设一个未知数为x，另一个未知数用含x的式子来表示，进而列并解方程即可．

小姑娘非常爱姐姐，店主非常感动

用解方程
解设姐姐存了x元,则弟弟存了（260-x）元
2/3x=260-x-10
2/3x=250-x
2/3x+x=250-x+x
2/3x+x=250
5/3x=250
x=250÷5/3
x=150
弟弟存了
260-x
=260-150
=110

甲、乙两个长方体容器的底面积之比为4：3.甲容器水面比乙容器水面高4cm,再往两个容器中注入同样多的水,恰好容器中的水深都是25cm.原来甲容器中的水深多少厘米?
特殊值法.
设甲乙两容器底面积分别为4x,3x.
由题意得：
甲容器水体积：4x×25
乙容器水体积：3x×25
甲水体积－乙水体积＝25x立方厘米
即“甲比乙水面高了4厘米”,就是体积高了25x立方厘米.
设甲水面原高y厘米,则乙水面是（y－4）厘米.
4xy－3x（y－1）＝25
解之得：
y＝13或16
答：原来甲容器中的水深13或16厘米.

华连卡姐弟是有新思想敢说敢为的年轻人,代表了一种新生的进步的力量.柯瓦连科和别里科夫的冲突,展示了新旧两种思想的矛盾斗争,而且淋漓尽致地鞭笞和讽刺了别里科夫腐朽反动的本质.尽管别里科夫的死并不等于反动腐朽势力的灭亡,但华连卡姐弟的出现,却使人看到新思想的力量.比如华连卡自由大方的骑自行车,还有科瓦连科和别里科夫的正面冲突,都表现了她们的进步

很多啊,山啊,水啊,花草树木,都是啊!
已经渐渐习惯了春夏秋冬的交替,它们的变更已不能像儿时那样使我欣喜了.也许是什么将它们同化了吧,像被砂轮磨去了原有的独特的棱角,变得越来越相似.而当我离开故乡的夏天又回来时,才发现,我还是那么的留恋,留恋它独有的味道,是我无论在草原还是海滨的夏天都没有找到的味道.过去最爱的是屋后的那座花园,尽管它现在已失去了那分野趣,变得精致、美丽,却挥不掉曾经的影子,尤其是在夏日.土地上长满厚厚的草,柔软温暖,拥簇着躺在草中的人儿,翻个身,惊动了懒懒的晒着太阳的蟋蟀,于是它便开始了不绝于耳的歌唱,为那悄然逝去的快乐时光.走在并不古旧却布满绿色地衣的石板路上,空气中飘来阵阵不知名的花香,既而便感觉到蜜蜂呼唤同伴的信号声.花园中自然是有池塘的,琥珀色的水上漂着几朵洁白的雪莲,在鱼儿们游戏中荡起的波浪里轻轻摇摆,那些令人怜爱的鱼儿啊,一嗅到夏天的味道便欢欣雀跃起来了,唉,真想扎进清澈的水中做一只身姿轻盈的彩鲤,和它们一起同大朵大朵白云的倒影嬉戏.天空的蓝,蓝得比湖水更清,比海水更纯.云朵们拉起手聚拢来了,连成一大片铅色,布满天空.感觉不到丝毫空气的流动,凝重得像一根散着丝丝雾气的棒冰.它慢慢下垂,一点一点,终于,雨滴落下来,在空中织起了一张密密的、无形的大网,将一切都装了进去.眼前的一片绿叶被雨击打着,一下一下,将它一点点打落,飘走了,跟随着微凉的风和土地的清香,它落在小溪里,那流淌的绿色,流进了眼睛,流进了心里.在云彩化成雨水流尽了之后,夜也接踵而至,黛蓝色的天穹中升起一轮月亮,是如此亲切又如此明亮,像一个神采奕奕的精灵,将柔光远播四方,溢满了整个宁静幽深的夜空.夜晚的微风轻轻哼唱着摇篮曲,哄着大地上的生灵进入梦乡,树枝上的蝉儿也乖乖地降低了鼾声,惟恐将夏夜的宁静打碎了.我整夜在夜空中徘徊,贪婪地嗅着夏天的气息,我想用手把清晨的霞光遮住,因为第二天,我的故乡的夏天将挥手与我告别,等待下一次相遇.

Living in the present
“Yesterday is history.Tomorrow is mystery.Today is a gift.That’s why it’s called present.” Who put it so?I’m not sure,nor do I care,but I do like it.Why?Because I’ve tasted the real flavor of the saying through my own experience.
Back to the first days I entered my college,I was more sad and lost than excited.Seeing so many of my former classmates enrolled in famous high schools,I was much distressed and down-hearted.I kept thinking of the past days when at junior high school.How I regretted the time I wasted that I should have studied.But it was only too late.Life and future are not easy for a vocational graduate in the present society.
I am delighted that now I have tided over the river.I know it is useless and futile to dwell on the past.The past is past,it is dead,and it is not healthy for us to linger over it.We should live in the present instead of past.
Tomorrow is mystery.It is also useless and futile to worry about the future.As many of the things remains unpredictable or unable to control.And this kind of unpreventable future things can really ruin our lives if we worry too much about them.There is nothing we can do except living well in the present.
To live in the present,we should learn to cherish the gift given by God.This very gift is to the time today.We must fully awake that our time at school is more precious than any other period of our life,because it is the golden period for us to acquire knowledge and develop ourselves.If we allow these morning hours of life to slip away,we shall never be able to make up for the loss.But if we use them properly,they will yield us innumerable advantages.In this increasingly fast changing world where competitions are everywhere,time definitely means opportunity and success.What we can or should do is to make every day count.
We are alive,let us live.We have the ability to experience,let us experience.We have the ability to learn,let us learn.The meaning of life can be grasped in a moment.A moment so brief it often evades our perception.
The great leader Chairman Mao once wrote,“So many deeds cry out to be done,and always urgently.The world rolls on,time presses.Ten thousand years are too long,seize the hour,and seize the day!” Let us remember the famous remarks and live in the present.
Thank you.

解题思路：根据题意，设姐姐现在的年龄是x岁，那么弟弟现在的年龄是（26-x）岁；姐姐当年的年龄是（26-x）岁，弟弟当年的年龄是（x÷4）岁，根据两人的年龄差是个不变量，列出方程进行解答即可．

设姐姐现在的年龄是x岁，那么弟弟现在的年龄是（26-x）岁；
根据题意可得：
x-（26-x）=（26-x）-x÷4
2x-26=26-x-x÷4
3x+x÷4=52
12x+x=52×4
13x=208
x=16；
那么弟弟现在的年龄是：26-16=10（岁）．
答：弟弟现在的年龄是10岁．
故选：C．

10个.
说明：“又把剩下的一半给了爷爷,这时自己还剩3个”,那就是给爷爷的也是3个.
所以4+3+3=10

(3/2-1+5)*4=22
(3/2+4)*(5-1)=22

大概用不着两个未知数吧?
设苹果x千克,则第一次卖掉了（1/2）x,第二次卖掉了（1/2）x*（1/2）=（1/4）x,总共卖掉了：
（1/2）x+（1/4）x=（3/4）x,得方程：
56-（3/4）x=17
x=52
则筐重56-52=4千克.

《我的烦恼》
成长的步伐到来了,成长的烦恼也紧随而来.让人整天都笼罩在忧郁中.
“你怎么这么粗心,英语的大写字母写成小写字母；数学不是小数点忘了加,就是死脑筋转不过弯；语文也是,不该错的总是错.……成绩总是没有提高!”从上初一开始,这类话就常常在我心头萦绕.有时候是父母批评的话语,有时候是我的自训,有时候却是妹妹的挖苦.
我也想要把成绩提高上去,不过总不能称心如意.不是这一科失手,就是那一科败下阵来.这些都是我始料未及的.谁不想考个好成绩,可是每个人的能力不同,所尽的努力也不同,所以收获的“果实”也有干瘪和饱满之分.因此我也只能说一身一声：“尽力而为!”了.
人生有竞争才会精彩——这是我安慰自己的话.但尽管如此,仍有不少烦恼让我挥之不去：作为一名学生,我告诉自己成绩不能太差；作为女儿,我告诉自己不能让父母大失所望；作为姐姐,我告诉自己要给妹妹一个好榜样……因此,烦恼也就日益增多.
可是反过来想想,如果好成绩那么容易就让我得到,那岂非大失它本身的意义,也失去了人们想要拥有它的欲望吗?这样想想,烦恼固然减少了许多.却有另外一种看法在脑海中形成——这以上的话虽具有一定的道理,但未免太过于幼稚,就有点像吃不到葡萄就说葡萄酸.没有努力争取,好成绩是不会送上门来的.所以,烦恼仍像一个影子,无时无刻都在跟随着我.这也许是庸人自扰,但的的确确,这应该是大部分同学所面临的烦恼.
要解决这个烦恼的办法是学习,学习,再学习.“最近比较烦,比较烦……”我现在终于明白这首歌曲实际上唱出了我们青少年面对学习的烦恼所表现出的无助与茫然.成长的烦恼在不断涌来,希望我们能招架住所有烦恼的“袭击”,学着在烦恼中健康成长!
