宋江 孝义黑三郎,讲的是他对待父母,讲究孝道,他的孝道贯穿到了他的思想当中,成为他思想的一个部分,并且是他的思想的一个很重要的支撑点；及时雨,讲的是他仗义疏财,扶危济困,这在后面他陆续和弟兄们交往中能够看得出来,在这一点上他做得到位.呼保义.这四个绰号实际上重点介绍了宋江平时的为人和喜好,而且都是正常工作之外的表现,比如“爱习枪棒”、“ 挥金似土”、“ 排难解纷”、“ 扶人之困”等等,这些好处多都具有一些江湖上的感觉,在民间宋江是一个喜欢做好事、愿意做好事的热心人,无论是在家庭伦理上还是在社会关系中他以自己的作为赢得了大家普遍的认可.

我来帮你,别忘了加点悬赏分.
两人各加18本,他们的本数差不变.前面相差4份,后来相差1份.说明前面的4份相当于后面的1份.后来哥哥2份,弟弟1份,共3份.要和后来的本数一样前面就应该是4×3=12份,但实际哥哥5份,弟弟1份共6份.所以多了12-6=6份,多的6份是各加18本的,所以6份对应36本,那么1份对应6本.于是哥哥原来有
6×5=30本.

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.

你这是几年级的问题~数据这么不详细.有没分外轮跟内轮的……如果不分就直接当他是个圆,直径为66,那半径就是33,圆的周长不久66*3.14

要分的桔子有X个.弟弟分到：x/2+1个,剩下：X/2-1个,哥哥分到：(X/2-1)/2+1.所以：
X-(x/2+1)-[(X/2-1)/2+1]=3,等X=18个.
也就说：弟弟分到了10个,剩下8个,哥哥分到了5个,最后剩下3个.

82/4=20.5 20.5是弟弟的!20.5*3= 61.5
也可以演算20.5+61.5=82

“三接”重音“三届”
复为 “重复".

楼上的都看清楚好不,后半句那是弟弟和哥哥的比.
哥哥弟弟的总钱数不变,一开始可以分为12份.给完钱后可以分为7份,那么总钱数可以分为12*7=84份,再来看一开始7:5,在84份中哥哥拿了49份,弟弟拿了35份.给了钱后弟弟和哥哥比4:3,哥哥拿了其中的36份,弟弟拿了48份,所以就是520元是84份中的13份,520÷13=40元.
40×36=1440（元）
好了
选我吧选我吧,嘿嘿

简单点来说 最常用的是

如果觉得没办法用一句话来说清楚,建议用几句简单的句子来描述：
The man is Amy's elder brother and he is also Tom's elder brother.
或：The man is Amy's and also Tom's elder brother.

yes,I do,这是一个删减句,补全后应该是,yes,I have a brother.也就是说把have a brother这个动词词组缩写成do这一个词了,否定句也是同理.

解题思路：根据题意，兄妹两人同时从家出发去学校，哥哥到学校立即返回又行了180米遇到妹妹，这时哥哥比妹妹多行180×2=360米，哥哥每分比妹妹多行90-60=30米，用哥哥比妹妹多行的路程除以速度差，就可以求出相遇时间，根据速度×时间=路程，用妹妹的速度乘相遇时间加上180米，计算家到学校的距离．由此列式解答．

60×[180×2÷（90-60）]+180
=60×[360÷30]+180
=60×12+180
=720+180
=900（米）
答：他们家离学校有900米．

点评：
本题考点： 相遇问题．

考点点评： 此题解答关键是先求出哥哥到学校又返回和妹妹相遇时多行了多少米，用哥哥比妹妹多行的路程除以速度差，就可以求出相遇时间，再根据路程、速度、时间三者之间的关系，列式解答即可．

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.
