数据结构要全面的说 我说不出来,但我可以用 其实也并不是说不出 只是不知道从哪说起 我想你一定有自己的理解,你不如说出你疑惑的地方,大家一起探讨.
我简单的说,首先数据结构就是 ,存在某种关系的数据的集合,比如数组,结构体,链表,等.然后看这些数据之间是什么关系.由他们之间的关系决定它属于那种数据结构,是线性结构还是非线性,但我们真拿来用时根本不需要管他是线性还是非线性,比如数组,你只要掌握数组的用法,自然就会想到在什么情况下用它,我觉的你根本不用在乎数据结构是什么.

你说的不错.过去将来时也可以表示过去经常发生的习惯或者动作.但是一般过去时的动词是根据人称变化的,过去将来时不管人称是什么动词都用would .而且一般过去时更加强调过去某一时刻的动作、状态,而过去将来时在表示过去的习惯、动作时更侧重于连贯性,翻译时常常可以加上总是二字.
比如：He didn't recognise you when you came here.他没有认出你来.这句话描述的场景肯定已经过去了.主语动词是did,也就是do.
而用过去将来时的话,就要这么说：He wouldn't recognise you when you came here. 他总是认不出你来.主语动词是would.
这样讲的话,你能明白吗?

对于诸位的回答,我不敢苟同.
实际上,任何液体或者类似于液体的物质都有一个特点,那就是在相同的体积下,如果不受到外力的影响,物体就会趋向于表面积最小的形状,也就是球体.
这个现象在生活中非常普遍,比如肥皂泡是球型的,水滴是接近于球形等等.
在恒星的组成部分是气体,也具有这个性质,行星的产生过程中,最初也都是熔融的液体,后来才逐渐冷却的.而且行星的自传使其发生形状的变化,例如地球就是一个椭圆体.
关于万有引力导致自转,这个比较可笑,九大行星中,水星是没有自转的,它难道不受到太阳的引力吗?彗星也受到太阳的引力,为什么形状特别?
关于宇宙的问题,根据宇宙大爆炸的理论,人们目前普遍认同宇宙是有限的,不断膨胀中的.

表示 一个坚持insist.二个命令order./command.三个建议advise/advice/suggest/suggestion/propose/proposal.四个要求(require/request/demand/urge)的名词后如果有同位语从句.或是动词后宾语从句.表语从句这些名词性从句等.都 用should +动词原型.should可省略.如
His suggestion is that we should start now .表语从句是根据前面的suggestion的意思而用了虚拟.
He suggested that we should start now.宾语从句也是由于suggestion这个词用了虚拟.
His suggestion that we should start now is reasonable.同上.

这题目我在英语贴吧有详细的解答,北京外国语大学专家薄冰教授就认为是“宾语从句”.同一学校的张道真教授认为是“原因状语从句”.他们都是正确的!

因为56万吨的船是很大的船,现在已经不再使用,也不再制造了,成本核算后不经济,因此现在10万吨的货船是最大的了,30万吨的也就是油轮.当船空载的时候吃水是很浅的,但是满载后吃水就变得很深了.也就是运河的吃水能力是25万吨满载,或者56万吨空载能力.两者的吃水深应该大致一样.

The Great Blue Yonder' by Alex Shearer 2001
作者简介：
Alex Shearer started his writing career as a scriptwriter and has had great success in that field.His credits include The Two of Us,the 1990s sitcom starring Nicholas Lyndhurst.More recently he has started writing for children.His Wilmot stories have been adapted for TV by Yorkshire television,and his children's novel,The Greatest Store in the World,was screened as a feature length TV film on Christmas Eve 1999 by the BBC.Alex's recent novel 'The Speed of the Dark' was shortlisted for the 2002 Guardian Fiction Prize
内容简介,和感悟如下：
You'll be sorry when I'm dead.That's what Harry said to his sister,before the incident with the lorry.And now he is just that - dead.And he wishes more than anything that he hadn't said it.He wishes he could say sorry.And say goodbye to everyone he left behind - his mum,his dad,his best friend Pete,even Jelly Donkins,the school bully.Now he's on the Other Side,waiting to move on to the Great Blue Yonder.But Harry doesn't know how to get there - until he meets Arthur,a boy in a top hat who's been dead for years,who helps him say goodbye...A poignant,funny and powerful book about grief - which makes death seem a bit less frightening,without ever patronising the reader.An astonishing,life-affirming read.
Narrated by 12 year old Harry after he is hit by a truck and dies,this is an interesting and ultimately upbeat book.Harry wanders around the Other Side,roaming through the adults who have died and meeting another young boy who has been dead for 150 years.The two pair up as Harry learns his way around the afterlife,even as he wonders about the Great Blue Yonder marked on the map he was given the day he arrived.Instinctively he knows that he cannot move on until he finishes his business on earth,notably forgiving his sister for her harsh words before he died and in turn forgiving hers back to him.Just before he raced off on his bike and was hit,his sister Eggy had told him she wished he would die and he said she'd be sorry when he was dead.Certainly not the last words you want to ever say to a loved one on either side.And so as he and his buddy Arthur zip around the Other Side trying to find Arthur's mother,Harry ponders how he can indeed apologize and free Eggy and himself.When Harry and Arthur go back to Earth,they look in on Harry's old school,his best friend,his enemy,and his family and Harry learns some truths about who he was in life and how his absence has affected everyone and it's not exactly as he's imagined it.
Shearer keeps the tone of the story light and Harry's active imagination,even post-death,is entertaining.Harry is very definitely a 12 year old boy with all that that entails and so middle schoolers will definitely relate to him and his anxieties.The other characters are really incidental to Harry's quest to make things right and we only ever see them through his immature eyes but his dawning understanding of life and his earthly relationships makes this dead character experience believable growth.The moral of the story is well handled and doesn't overwhelm the charming character of Harry or of his experiences after death on the Other Side and back on Earth.

1、铅球的密度p=m/V=4/(0.57*10^-3)=7017.54kg/m^3
2、按说明书,钱和铁的质量各是2kg.则铅的体积=m/p铅=2/11300=0.000177m^3=0.177dm^3
铁的体积=m/p铁=2/7900=0.000253m^3=0.253dm^3
总体积=0.177+0.253=0.43dm^3
3、按照说明书体积应该是0.43dm^3,实际体积是0.57dm^3,所以是空心的.空心体积是0.57-0.43=0.14dm^3

　　我去翻看了一下原著,我认为,桑乔从被认命总督到离职总共10天,但桑乔只在小岛呆了8天.也就是说他被大多数人认为当总督的时间是10天,而真正做总督是8天.
　　为什么是八天,我在后面会说明.首先我说说为什么文中会出现这样“七天,八天,十天”不同的时间.当公爵承认桑乔为总督时,公爵已经派人去了小岛,承认桑乔作为该岛总督.所以桑乔到达时,岛内早以准备好了.而桑乔在岛上身边的人大多都是公爵派遣陪着他一起去的人,知道事情的原委,这其中最明白的大概就是管家.有几个地方可以说明：
　　1、第五十三章里这句话,“这是桑乔当总督的第七天晚上…”显然这是讲这个故事的人的叙述,或者可以说作者认为桑乔现在当了七天.也就是在这天晚上,一群人说小岛被进攻,桑乔被愚弄后决心辞职离开.其实桑乔被打晕后是在第八天凌晨苏醒的（原话“桑乔问现在是什么时候,大家说是凌晨…”）桑乔骑上驴后,说出了一段话,这段话就是正式说辞职的(所以说他实际在岛上当了8天总督）.当桑乔走时,之前陪他一起来的管家（假扮忧伤妇人那位）说：“你就谈谈您当这十天总督的情况…”显然,管家一开始在公爵家时就知道桑乔当了总督,所以才这么说.（其实,管家是为了回去复命,公爵让他记录关于桑乔当总督有趣的事.）对此,桑乔回答时并未否决十天的说法.
　　2、回来的路上,桑乔掉进了一个坑里,公爵派人把他救出来,“一个学生模样的人”说“所有坏总督离职时都应该是这样…”.看看我们桑乔反驳的其中一句话：“...在八天或十天以前,我得到了一个岛屿,当上了总督.”显然,桑乔也有些确定自己到底当了几天,之前他自己认为是八天,而听了总管的话后开始怀疑自己.而后来当桑乔回到城堡,见到公爵夫妇“长篇大论说了一通”,其中他说“他当了十天总督,所得的收获就是认识到,别说当一个海岛的总督,就是当全世界的总督,他也无所谓了.”桑乔很爱吹牛,在那一大段话里干脆就吹了一半,所以就说自己当了十天.
　　以上都是个人看法,楼主仅供参考.

一般介词后面接名词,动名词,代词 --- 反正都是名词性质的.你说的加形容词、副词等情况也有,这时往往是省略了名词,例如：He is dressed in black.这句话你可以看做省略了名词clothes.这种情况并不很多,遇到时你就把它作为习惯用法记住就行了.语言是非常灵活的,即使是汉语有些东西你也不一定能解释清楚,所以学习语言切不可钻牛角尖.
