真可

应该选择B,因为前面的先行词被every所修饰,所以主语应该被看作是第三人称单数

C语言选举代表问题

错误的地方比较多。首先,字符串的存储一个汉字要占两个字节的位置,所以两个汉字就要用了4个字节,另外再加上一个字符串的结束服务,表示两个字的姓名,就需要至少需要五个字符。另外,比较致富串是否相等,应该要使用头文件string.h。下面比较字符串是否相等,要使用其中的字符串比较函数strcmp。具体的程序已经修改完成,并且运行测试通过。#include#include main(){ int i,k; char j[5]; //两个汉字至少要5,三个汉字至少要7 struct person { int votes; char j[5]; } zhang= {0,"张三"},zhao= {0,"赵六"},wang= {0,"王二"},li= {0,"李四"},liu= {0,"刘五"}; for(i=1;; i++) { printf("请输入支持人的姓名,结束请输入## "); scanf("%s",j); if(strcmp(j,zhang.j)==0) zhang.votes++; if(strcmp(j,wang.j)==0) wang.votes++; if(strcmp(j,zhao.j)==0) zhao.votes++; if(strcmp(j,liu.j)==0) liu.votes++; if(strcmp(j,li.j)==0) li.votes++; if(strcmp(j,"##")==0) { break; } } printf("1 %s %d ",zhang.j,zhang.votes); printf("2 %s %d ",wang.j,wang.votes); printf("3 %s %d ",zhao.j,zhao.votes); printf("4 %s %d ",liu.j,liu.votes); printf("5 %s %d ",li.j,li.votes);}

这个c语言程序怎么改???if(strcmp(na,can[i].name)==0)这个是错的吗???

strcmp是c的库函数,功能是把()中的形参指针指向的字符串比较一下,按对应字符的ascii码大小确定返回值:前者大于后者时返回1,相等时返回0,前者小于后者时返回-1。strcmp(name,eng[i].name)的意思就是比较name和eng[i].name指向的字符串谁大谁小或相等。

豆瓣和imdb的评分哪个专业点

简单的说imdb更具有客观性,豆瓣更适合国人的口味,时光网评分普遍偏高不具有参考价值。我觉得这么问,目的在于这个评分是否对于我们有参考价值,是否能影响我们买票走进电影院,所以我觉得需要从几个方面来看待这个问题。首先,votes。imdb分数并不能完全反映电影的水平,同时需要考虑vote数,比如>1000 votes或者>2000 votes。有些片分高,但是votes数很少,这样就没有参考价值,一般超过1w的votes就能正确反映片子的水平了。这个到豆瓣上同样适用,基数越大,分数越具有参考价值。另外亚洲的片子在imdb上普遍votes太少,基本上不具有参考价值,亚洲的电影还是参考国内的评分比较好。其次,地域文化差异的问题。众所周知,由于天朝的GFW,国内用户是没办法直接访问imdb的,需要翻墙或者把域名改成ip地址。因此imdb的评分大部分只代表了欧美用户的口味,并不一定适合于国人的口味。有很多片子在国外评价很差票房很烂,国内引进却能获得不错的票房和口碑。上段说到亚洲电影普通votes太少,也是欧美大众很少有机会接触到亚洲的电影,华语电影就更难了,很多日韩港片几乎没有imdb链接,因此这些imdb的评分完全不具有参考价值。再次,评分机制。imdb的评分是可以选1--10分的,而豆瓣只能选1到5星,这种差异也会造成不同分数的差异,比如我在imdb上很少给片子10分的,因为我认为很少有一部电影能够达到10分,往往很不错的我就给9分了,而在豆瓣上5星表示力荐,9分的电影我觉得已经足够力荐所以我当然会给5星。这也是分数有差别的一个原因。普遍来说,一部公认的好片在豆瓣上分还是会高一点的。次次,在imdb上,会有刷分的问题。就是说top50,top10的电影是相对固定的,每年顶多1到2部电影能进入到top50里面,而top10的电影也是有一批固定的粉丝的,他们对于自己喜欢的电影是无法忍受被其他新进来的电影刷下去的。比如当初TDK被粉丝们刷到TOP1的时候,肖申克救赎的影迷和教父的影迷就无法忍受了,于是刷分就开始,把后两部评分往上刷把TDK往下刷,最终TDK的评分在8.9,No.8。所以一般一部电影上映之后1年分数和排名才会较为稳定。最后,说到底电影的评价完全在个人。一百个人眼中有一百个哈姆雷特,这和你自己的口味以及人生阅历是有关系的,分数只是一个简单的参考,只是影响你买票走进电影院的一个因素而已。很多动作片分不高6分,但是也可以一看;有些文艺片7分,也不一定看的很舒服;有些片快8分了你也不一定能看懂。也有很多人看片只要是大片就看,也有人只要有自己喜欢的明星就行,也有人只喜欢看某种类型的片。当然,如果你只是一位为了没事放松自己进电影院看一部电影的话,我觉得你可以综合imdb和豆瓣的评分来决定是否要买票进入电影院。

statutory voting system到底是什么样的投票方式?

What is "Statutory Voting"Statutory voting is a corporate voting procedure in which each shareholder is entitled to one vote per share and votes must be divided evenly among the candidates or issues being voted on. Statutory voting, sometimes known as straight voting, is one of two stockholder voting procedures and the more common option. In statutory voting, if you owned 50 shares and were voting on six board positions, you could cast 50 votes for each board member, for a total of 300 votes. You could not cast 20 votes for each of five board members and 200 for the sixth.

求一篇有关环境的英语新闻报道,其中有对话采访!

Britain Enters Final Day of Campaigning Before ElectionsBritain"s top party leaders are taking full advantage of their last day of campaigning before Britons go to the polls. Late Wednesday night, Labor leader Gordon Brown visited steel workers on an overnight shift. "I don"t need to tell you that this election is about the future," said Brown. "It"s about the future of our industry, the future of our jobs, the future of our young people." Mr. Brown is facing a tight election. The Conservative Party, led by David Cameron, has topped the latest opinion polls. And, the Liberal Democrats -- traditionally a marginalized party in what has largely been a two-party system -- are scoring high in opinion polls.Rodney Barker is a political academic and professor at the London School of Economics. "The three candidates have been up to making themselves as busy as possible," explained Barker. "David Cameron, the Conservative leader, so visible that he"s even worked through the night -- he hasn"t slept."Barker says this last day of campaigning is crucial, because so many Britons still have not made up their mind. A survey published by the research group ComRes Tuesday said 2.5 million people who say they are certain to vote say they are still undecided who to vote for and more than a third of voters said it was "quite possible" they would change their mind on who to vote for by the time the polls open Thursday morning. Rodney Barker says it is all up in the air."The one thing which one can say about this election -- and we haven"t been able to say this for any election within living memory -- is that the only certain thing is that we cannot predict the outcome, even on the day before the poll," added Barker.The ComRes poll shows the Conservatives winning 37 percent of votes, Labor on 29 percent and the Liberal Democrats on 26 percent.With the votes split this way, no single party would win a majority of seats in parliament. In that case, the shape of Britain"s future government will depend on coalitions. The balance is likely to be tipped by the Liberal Democrats, but so far their leader, Nick Clegg, has refused to say whether his party would side with the Conservatives or Labor. Barker says what this means is that it could be weeks before the composition of Britain"s future government becomes clear. "Even when we know the result of the election, we may not know what the result is in terms of government -- who will successfully make a deal with who to make what sort of government," noted Barker.If no single party is able to win a majority of parliament seats, current Prime Minister Gordon Brown would have the right to stay in office until a new government can be formed.

IMDb权威认证是什么

IMDB 基于网友的个性海量评分,其核心排名算法如下: The formula for calculating the Top Rated 250 Titles gives a true Bayesian estimate:   weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C      where:   R = average for the movie (mean) = (Rating)   v = number of votes for the movie = (votes)   m = minimum votes required to be listed in the Top 250 (currently 3000)   C = the mean vote across the whole report (currently 6.9)      for the Top 250, only votes from regular voters are considered.http://movie.douban.com/doulist/1518184/如果有兴趣可收藏此豆列,录有最新的IMDB TOP250

如何查询一部电影在IMDB中的具体排名?

环球电影资料库里有,几乎所有的电影资料都能在上面找到.也有IMDB排名.参考资料:http://www.mov6.com/IMDB评分方法IMDB是目前全球互联网中最大的一个电影资料库,里面包括了几乎所有的电影,以及1982年以后的电视剧集。IMDB的资料中包括了影片的众多信息,演员,片长,内容介绍,分级,评论等,就个人买碟而言,很大程度上也是参考IMDB的得分。而IMDB的得分又是如何来的呢?它的可靠性又有多少呢?让我们通过《魔戒1:护戒使者》来做具体分析吧,先看上图:这张图就是魔戒1的所有评分者的分数的一个条状统计图。从中我们可以看到各个分数段的大致比例,比如这儿就可以发现,超过一半的人是打满分的。根据IMDB网站上公布的TOP250评分标准:imdb top 250用的是贝叶斯统计的算法得出的加权分(Weighted Rank-WR),公式如下:weighted rank (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C其中:R = average for the movie (mean) = (Rating)(是用普通的方法计算出的平均分)v = number of votes for the movie = (votes)(投票人数,需要注意的是,只有经常投票者才会被计算在内,这个下面详细解释)m = minimum votes required to be listed in the top 250 (currently 1250)(进入imdb top 250需要的最小票数,只有三两个人投票的电影就算得满分也没用的)C = the mean vote across the whole report (currently 6.9)(目前所有电影的平均得分)另外重点来了,根据这个注释:note: for this top 250, only votes from regular voters are considered.只有‘regular voters‘的投票才会被计算在IMDB top 250之内,这就是IMDB防御因为某种电影的fans拉票而影响 top 250结果,把top 250尽量限制在资深影迷投票范围内的主要方法。regular voter的标准不详,估计至少是“投票电影超过xxx 部以上”这样的水平,搞不好还会加上投票的时间分布,为支持自己的心爱电影一天内给N百部电影投票估计也不行。因此,细心的人可以注意到,列入IMDB top 250的电影,其主页面上的分数与250列表中的分数是不同的。以魔戒1为例,它在自己的页面[url]http://www.imdb.com/title/tt0120737/[/url]中的分数是8.8,而列表中是8.7。一般 250表中的得分都会低于自己页面中的得分,越是娱乐片差距越大。这大概是因为regular voter对于电影的要求通常较高的关系。

求英语语法高手解惑,..题目如下

同意上面对28,29,34的回答。其它有不同看法:30题答案应该为B.otherwise,otherwise是副词,意为“否则的话”,全句意为:他应该是在工作,否则的话是在忙着。如果用else一般跟or的后面,而but的后面常跟otherwise31.全面有having received...,表明此动作在前,故后面不用to have been33.整个句子都是逗号,所以答案应该是which,其它答案均错,从语法上是不成立的。

请问什么是IMDB评分?

IMDB是目前全球互联网中最大的一个电影资料库,里面包括了几乎所有的电影,以及1982年以后的电视剧集。IMDB的资料中包括了影片的众多信息,演员,片长,内容介绍,分级,评论等,就个人买碟而言,很大程度上也是参考IMDB的得分。 而IMDB的得分又是如何来的呢?它的可靠性又有多少呢?让我们通过《魔戒1:护戒使者》来做具体分析吧,先看上图: 这张图就是魔戒1的所有评分者的分数的一个条状统计图。 从中我们可以看到各个分数段的大致比例,比如这儿就可以发现,超过一半的人是打满分的。 根据IMDB网站上公布的TOP250评分标准: imdb top 250用的是贝叶斯统计的算法得出的加权分(Weighted Rank-WR),公式如下: weighted rank (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C 其中: R = average for the movie (mean) = (Rating) (是用普通的方法计算出的平均分) v = number of votes for the movie = (votes)(投票人数,需要注意的是,只有经常投票者才会被计算在内,这个下面详细解释) m = minimum votes required to be listed in the top 250 (currently 1250) (进入imdb top 250需要的最小票数,只有三两个人投票的电影就算得满分也没用的) C = the mean vote across the whole report (currently 6.9) (目前所有电影的平均得分) 另外重点来了,根据这个注释: note: for this top 250, only votes from regular voters are considered. 只有‘regular voters‘的投票才会被计算在IMDB top 250之内,这就是IMDB防御因为某种电影的fans拉票而影响 top 250结果,把top 250尽量限制在资深影迷投票范围内的主要方法。regular voter的标准不详,估计至少是“投票电影超过xxx 部以上”这样的水平,搞不好还会加上投票的时间分布,为支持自己的心爱电影一天内给N百部电影投票估计也不行。 因此,细心的人可以注意到,列入IMDB top 250的电影,其主页面上的分数与250列表中的分数是不同的。以魔戒1为例,它在自己的页面http://www.imdb.com/title/tt0120737/中的分数是8.8,而列表中是8.7。一般 250表中的得分都会低于自己页面中的得分,越是娱乐片差距越大。这大概是因为regular voter对于电影的要求通常较高的关系。

If paul had received six more votes in the last election,he?

A 首先在A和B两个选项中选,因为题目已经确定是虚拟句所以肯定是过去时态,而从句是过去完成时态,主句是表示的"现在",所以就是过去时态了.(根据虚拟句的法则,是过去的事情那么从句就用过去的过去即过去完成时态)而B选项的意思是"本该```"的意思,如:you should have finished your homework before supper.你本该在晚饭前完成作业.,2,a 条件句过去时虚拟语气 主句现代时虚拟语气 结构:would + do,2,A 很简单,用不着一堆语法解释。条件句是对过去的假设,主句是对现在的假设,都是虚拟的,就都按照正常时态倒退一个时态就好了。,2,D,2,答案 是 B 因为是对过去条件的 假设 是虚拟语气句型,2,B,2,选择B,过去将来时,俺是凭语感得出答案的,不用说了,你问问老外,肯定是B 如果paul在上次的投票中得到多于6票的选票,那他现在就应该是我们的主席了 这样看看,选什么?,1,A 这是个混合虚拟语气,从句是对过去的虚拟所以用的是had received,而主句是对现在情况的虚拟(用了时间状语now),所以用的是would be。,0,If paul had received six more votes in the last election,he ______ our chairman now. A.would be B.would have been C.will be D.must have been. 请说出选择的理由. 可是我的语感告诉我是B。 我很难理解A的感觉!

outlook 和perspective区别

outlook 本意“景色”,引申为2个意思,其一是“(对生活等的)看法, 观点, 态度”,其二“事物发展的前景”perspective本意“远景”,所以有“透视法”的意思(艺术上的术语,古代的人绘画以前都是平面感觉的,直到有了透视法,绘画才有远近的感觉),这里要格外注意的是,perspective具有"观点,看法"的意思,但是和outlook的“观点”意思不同,下面就这个方面详细探讨一下。perspective的“观点,看法”是指对待事物的思维方式(a particular way of thinking about something)例如:the events in their historical perspective 用历史的观点看待这些事件 outlook的“观点”强调的是“生活态度”(general attitude towards life)例如:I adopted a positive outlook on life...我积极面对生活。

酒渣样皮炎怎么治?

都说红苹果肌是美丽的象征,可如果是脸部肌肤长时间像苹果般红,那就是肌肤问题了,这种症状称之为酒渣肌肤,是一种皮肤炎症,医学上称之为酒渣样皮炎,该怎么治疗呢?1、酒渣样皮炎成因皮肤科医生表示,脸部潮红迟迟未退,伴随灼热感与红疹,是酒糟性皮肤炎的典型症,患者除了要注重保湿和防晒、保养简单化,适度透过药物和光照治疗,也能达到改善病症和美肤的双重效果。酒糟性皮肤炎是一种慢性、反复发作的皮肤病。酒糟肌成因多日晒、保养品、嗜辣都可能诱发新竹马偕纪念医院皮肤科主任李幼华表示,酒糟性皮肤炎是一种慢性、反复发作的皮肤病,初期症状常是两颊、鼻尖或下巴像晒伤般红红的,可能几小时或几天就会褪去。但是,随着皮肤越来越敏感,血管扩张越来越频繁、持续时间也拉长,患者可能因皮脂腺增生长出丘疹、脓_,或皮肤持续发炎导致软组织增生、表皮增厚形成“酒糟鼻”。酒糟性皮肤炎的原因不明,可能与遗传、荷尔蒙有关,这类体质的人血管较不稳定,加上如日晒、情绪压力、使用刺激性的保养或化妆品、爱吃烤辣炸,或太烫食物等因素诱发,微血管就容易扩张发红。如果微血管持续扩张,失去弹性无法回缩,最后脸部就会出现明显血丝。另外,有些酒糟性皮肤炎则是因为滥用类固醇引起。李幼华医生指出,有些病患长期使用类固醇治疗过敏、湿疹,忽略类固醇依赖会让皮肤萎缩变薄,加重微血管增生及泛红的酒糟症状,一旦停止使用,症状反而更严重。2、酒渣样皮炎症状与治疗一、酒渣皮炎的症状是什么酒渣皮炎是一种分布广泛的慢性顽固性皮肤疾病,不但痛苦,且治疗难度很大。据认为全美即有约一千四百万酒渣皮炎患者,其中女性患病率略高于男性。尽管酒渣皮炎患者众多,还是经常被内科甚至皮肤科医生误诊,很多人甚至不知道这种疾患的存在。美国全国酒渣皮炎协会(NationalRosaceaSociety)曾经做过一项调查,结果发现78%的调查对象不知道酒渣皮炎是什么,当然也不懂如何识别。简单地说,酒渣皮炎是一种很特殊的面部皮肤问题,最先的症状是鼻子和两颊出现标志性的蝶状红斑。起初这种“潮红”只是间歇性的,但是最终总是会加剧、过敏,同时伴随皮疹、毛孔粗大、痤疮和清晰可辨的毛细血管。如果你发现面部突然严重泛红(并非由于日晒或风吹过度),且不能很快消退,那么可能需要请教皮肤科医生。其他信号包括多处毛细血管破裂(通常破裂的血管在脸颊连成网状),以及类似青春痘的疙瘩和皮疹,但使用抗痘产品无效。二、酒渣样皮炎的治疗(1)酒糟肌无法根治妥当用药+脉冲光预防复发每个人的酒糟性皮肤炎成因不一定相同,切勿擅自涂抹先前旧药或成药,建议尽快就医寻求专业治疗。李幼华医生指出,跟其他皮肤炎的治疗比较起来,治疗酒糟相对花时间,患者也要更有耐心,尽管无法根治,但控制得好就能预防复发,不要让皮肤一直处于发炎状态。传统治疗酒糟性皮肤炎的方式,包括:口服四环霉素,或成分为Metronidazole的外用药膏,都具有抗发炎的功效,乙型肾上腺阻断剂则能抑制血管扩张,缺点是用药时间动辄1、2个月以上,且无法根除增生的微血管,仅能抑制微血管扩张的程度。而且,一旦产生持久性的红斑及明显的微血管扩张,药物改善程度有限,此时可运用脉冲光治疗,借特定波长的光线照射病灶处微血管,利用血液中红血球_含氧血红素吸收脉冲光的特性,光能转变为热能作用于血管壁,血管壁受热凝结萎缩,就能去除多余的血管组织,改善脸部潮红、血丝问题,回复均匀肤色。(2)生活养生学!保养简单化+着重保湿和防晒李幼华医生提醒,酒糟性皮肤炎患者肤质干燥敏弱,即使治疗后症状改善,平常也应重视保湿,避免去角质,保养或化妆品成分尽量简单化;外出记得擦防晒乳,也要加强撑伞、戴帽等物理性防晒,不要常待在三温暖或温泉等环境,少吃过烫或过辣的食物,以及情绪保持稳定,生活作息正常,尽可能减少诱发因素。3、酒渣样皮炎的饮食①皮炎患者宜多吃富含维生素A的食物。维生素A能维持上皮组织细胞的正常形态与功能,纠正毛囊皮脂腺角化异常,防止毛囊堵塞,皮炎患者适量补充可缓解干燥、粗糙、渗出等皮肤损害,帮助皮肤恢复健康状态。富含维生素A的食物主要有菠菜、苜蓿、豌豆苗、红薯、胡萝卜、青椒、南瓜、动物肝脏、奶制品、禽蛋等。②宜多吃富含B族维生素的食物。B族维生素主要包括维生素B.、B2、维生素B6、维生素B12等。其中维生素Bi被称为精神性维生素,大量存在于粳米、小麦、燕麦、花生等粮食作物以及动物肝、肾脏和大多数蔬菜中,能有效缓解压力,消除抑郁、愤怒、紧张、焦躁等不良情绪,对于神经性皮炎患者大有裨益;维生素B2富含于绿豆、红豆、黑豆、芝麻等谷类食物以及乳制品、动物肝脏、深绿色蔬菜中,能促进皮肤细胞再生,平衡体内新陈代谢,对于脂溢性皮炎、各种过敏性皮炎都有很好的辅助治疗功效;维生素B6能将蛋白质分解成年人体必需的氨基酸来促进酶的作用,从而在体内形成一种能增强皮肤抗过敏能力的抗体,鱼类、动物肝脏以及麦芽、燕麦、大豆、花生、核桃、卷心菜中的维生素B6含量较高;维生素B12具有强大的造血和细胞再生功能,可维持皮肤的健康状态,维生素B12主要富含于动物性食物中,如动物肝脏、牛肉、猪肉等。③宜多吃富含维生素C的食物。维生素C有保护皮肤、愈合伤口、抑制炎症、消除压力等作用,能帮助皮炎患者缓解皮损症状。常见的蔬菜和水果中都含有维生素C,其中以青椒、西红柿、花椰菜、卷心菜、芥蓝、草莓、橘子、樱桃、猕猴桃含量最为丰富。④宜适当补充锌元素。锌是一种维持酵素系统和细胞正常运作的矿物质,能够促进胶原蛋白的合成,可保护皮肤、促进伤口愈合,适当补充可预防皮炎发生、缓解皮损症状。锌含量丰富的食物包括肉类、动物肝脏、海产品、乳制品,禽蛋、大豆、全麦制品及各种坚果。

perspective改善英语

  perspective的本意是“具有通过透视看到的事物全貌特征的”.既然观察到事物的全貌,那么就应该是“全面/正确/客观观察到的”.因此,a perspective approach 的意思是“全面(或正的/客观)的观察方法”. u200du200d参考译u200d文:为什么关于发展的全面而客观的观察方法是重要的?

foreach 函数

foreach 函数和别的函数非常的不一样。因为这个函数是用来做循环用的,Makefile中的 foreach函数几乎是仿照于Unix标准Shell(/bin /sh)中的for语句,或是C-Shell(/bin /csh)中的foreach语句而构建的。它的语法是: 这个函数的意思是,把参数<list>中的单词逐一取出放到参数<var>所指定的变量中,然后再执行<text>所包含的表达式。每一次<text>会返回一个字符串,循环过程中,<text>的所返回的每个字符串会以空格分隔,最后当整个循环结束时,<text>所返回的每个字符串所组成的整个字符串(以空格分隔)将会是foreach函数的返回值。 所以,<var>最好是一个变量名,<list>可以是一个表达式,而<text>中一般会使用<var> 这个参数来依次枚举<list>中的单词。举个例子: 上面的例子中, (name)中的单词会被挨个取出,并存到变量“n”中,“ (n).o”每次根据“ (n)”计算出一个值,这些值以空格分隔,最后作为foreach函数的返回,所以, (files)的值是“a.o b.o c.o d.o”。 注意,foreach中的<var>参数是一个临时的局部变量,foreach函数执行完后,参数<var>的变量将不在作用,其作用域只在foreach函数当中。
