mean

mean to do，mean doing 和 be meant to 的区别有如下这些:mean to do是“打算，意图，企图”的意思；2.Mean doing是表示“意味着”的意思；3.be meant to do是，应做，照道理，照规矩应该做。双语例句:I had meant to leave on Sunday.我本打算周日走。2.I mean to stay here for a long time.我打算在这儿呆很久。3.Missing the train means waiting for another hour.赶不上火车预示着要再等一个小时。4.Revolution means liberating the productive forces.革命意味着解放生产力。5.I was meant to be working on Sunday, but I just fooled around all day.星期日我本应工作的，但却闲 混了一整天。

1、mean to do sth.“打算干…事”，如： I meant to give you this book today, but I forgot. 我本来打算今天给你这本书的，可是我忘了。 2、mean doing sth.“意味着…”，如： Missing this train means waiting for another hour. 错过这辆火车意味着你得再等一小时。

1、意思不同：mean to do的意思是“打算或企图做某事”，主语通常表示人。be meant to do是照规矩应该做。mean doing的意思是意味着。 2、用法不同：be meant to do是照规矩应该做。mean to do主语通常表示人，mean doing，其主语通常是指事物的词，主语一般为一个句子，一个事件。

mean to do和doing的例句如下：I mean to buy a vacuum next month.下个月我打算买一台真空吸尘器。Pushing or pulling does not necessarily mean doing work.推或拉未必意味着作功。含义不同：（1）mean to do sth.意为：打算做某事。例如：I am mean to go the supermarket.（我打算去超市。）（2）mean doing sth.意为：意味着…… 例如： There are many clouds in the sky that mean raining.（天空中乌云密布，意味着要下雨了。）用法不同：mean to do 后接动词不定式，表示打算做某事；mean doing 后接动词ing形式，表示意味着……主语不同：mean to do sth. 使用时主语通常是表示人的名词或代词。mean doing sth. 使用时主语通常是指事物的sth。

mean to do和mean doing的区别 mean to do和mean doing的区别如下： 一.means doing mean当做意思意味讲时,是及物动词,refusingto have anything to do with something or somebody这个动名词短语做mean的宾语. 二.mean to do一般理解为打算做某事 联合抵制这个词的意思是拒绝用某物来对付一些事或者一些人~ mean to do和mean doing的具体意思如下： ⑴mean to do 英 [mi:n tu: du:] 美 [min tu du] 词典意思为： 打算做；有意做 网路意思为： 打算; 打算做某事; 打算/想做某事 用法例句： 1.I didn"t mean to do you any harm. 我并不想会害了你。 forum.eyankit. 2.You are not mean to do that. 你不该做那个。 ⑵mean doing 网路 意味着; 意味着做; 意思是,意味着; 意味着做某事; 意味着干某事 用法例句： 1.Pushing or pulling, however, does not necessarily mean doing work. 然而，推或拉未必意味著作功。 blog.163. 2.This might mean doing some required reading or pleting a few *** aller steps ina project. 这可以是做一些必要的阅读或完成专案中的几个比较小的步骤。

mean to do是打算做什么，而mean doing是意味着做什么

前者打算做，有意做

she didn"t mean to break it: INTEND,

这裏是汉字吧，非汉译吧罢了，由我港民来解释吧……mean to do sth 打算做某事

Sam : If you are too nice to her, then she won"t like you either.Robert : But I like her. How can I be mean to her?Sam: 如果你对她太好的话， 她也不会喜欢你的Robert: 但是我喜欢她，我怎么能够刻薄地对她呢？mean 这里是苛刻的 卑鄙的 刻薄的 意思

过去的打算，没有延续到现在。

mean to do sth.的意思是“打算或企图做某事”,其主语通常是表示人的名词或代词,其过去完成式表示“本来打算做某事”.例如：What do you mean to do with it?你打算把它怎样处理? mean doing sth的意思是“意味着干某事”.

mean to do sth：故意做某事，打算做某事mean doing sth 意味着做某事。 mean做打算的时候，是to do sth，相当于intend to do mean作为意思，意味的动词时。要用mean sth或mean doing sth

meantodo打算做…；有意做...故意作某事Hetoldmethathedidn"tmeantodoit,andsoIgottobelievethat他说他不是故意的，所以我就相信了。-----------------------------------如有疑问欢迎追问！满意请点击右上方【选为满意回答】按钮

meantosth的意思是“打算做某事”；meandoingsth的意思是“意味着干某事”.到选择题里根据句义判断就可以了，没有什么特殊的用法，不过是两个动词短语。

mean doing sth. 意思是“意味着做某事”，mean to do sth. 意思是“意欲或意思是要做某事”。

mean to do打算做什么事,mean to 是不定式的省略开式,通常用在回答中,避免重复,省略不定式符号to 后的主要动词.但to 不能省,这是语法规定,就像汉语中,问,“你吃饭了吗?我吃了,”可以把饭省了.

和你遇到了同样的问题，在GOOGLE上搜到的答案。初始中心的文件，第一个变量就应该是cluster_，值为1-k（k就是类别数）。我按这个做了，就OK啦！问：I ran the SPSS Quick Cluster procedure for K Means clusteranalysis, specifying an SPSS file with the initial clustercenters. I received error message # 14024 which states:"The file referenced in the FILE subcommand does not havethe proper format for QUICK CLUSTER initial cluster centers."My cluster center file includes all the variables that areused in the Quick Cluster command and there is one case foreach of the centers. Am I missing something?答：The first variable in your cluster center file must benamed cluster_ . The values for cluster_ in the K rows willbe 1, 2, ... K, where K is the number of clusters. The absenceof cluster_ will trigger the improper format error message.Other essential properties of the centers file include:1. You must have at least as many cases in the center fileas the number of clusters specified in the QUICK CLUSTER command.If there are K cases in the centers file and J (J< K) clustersspecified in the QUICK CLUSTER command, only the first J casesfrom the centers file will be used.2. All the variables that are included in the QUICK CLUSTERcommand must be included in the centers file. Variable orderneed not be identical in the QUICK CLUSTER command and thecenters file (provided cluster_ comes first in the centers file).Variables in the centers file that are not in the QUICK CLUSTERvariable list will be ignored in the analysis.

★meaning of politics 是个短语，不是一句话。它的意思是【政治的含义……】，要构成一句话，后面应该加上系动词+表语，或谓语+宾语例如：the meaning of politics is .......(接表语或表语从句) the meaning of politics made us .....(政治的含义把我们.....（弄糊涂了等等）。或接其他谓宾内容)

哪儿来的这句，没法直译，要放入语境中意译

Directions:Some people say winning means being rich, some people say winning means being powerful, and other people say winning means being happy. Please write a paragraph of about 120 words about YOUR understanding of winning. Sample 1Some people say that winning means being rich, some say winning means being powerful, and others think winning means being happy. I think winning means doing what you should do and being good at it. Most of us can only live in this world for no more than 70 or 80 years. We shouldn"t think too much about what we can get from this world. Instead, we should think about what we can leave in this world. The one who can make more contributions to the world is a real winner. For example, cleaning the street is a humble job in many people"s eyes, but in my opinion, street cleaners can also be great winners. They make our city more beautiful. They give us a better environment and consequently a better life. On the contrary, some people make money at the cost of the environment. Some are even worse: They cheat or kill others in order to gain power or earn money. Winners or losers? It"s time to give it a second thought.The quadrennial choice for president is the only time all Americans vote on the same question. At the same time we do that, we also elect one-third of the Senators and the entire House of Representatives, but in smaller geographic units.It used to be that, if the winning side in an election did not have enough of a majority to pass its legislation, it knew it needed to compromise with the losing side. And the losers knew that they could influence the legislative outcome because the winners needed their votes. But, having lost the election, they tended to accept the fact that the winners got to set the agenda and the framework for the legislative solutions to problems and that their own role was to tweak - sometimes in important ways - the legislation.Now that the 2012 election is behind us, the first big question is whether or not the Republicans, having lost the White House and the Senate, will follow that tradition. Even more, it is whether John Boehner, as Speaker of the House can keep the members on his rightward fringe in check and be able both to craft compromises with the Democrats and to deliver enough votes that, when added to those of House Democrats, legislation can pass that moves the country forward on the many problems we face. If he cannot, How will the President respond? And what will he be able to do on his own, without legislation, to address those vexing problems.On one such issue, Barack Obama made it clear during the campaign that to get our fiscal house in order would require increased revenue as well as cuts in spending. More specifically, he argued that the megarich should pay more in taxes, the rest of us were already paying enough, and what money we had was needed to enable us to buy things and, thus, support demand that could, in turn, fuel the economic recovery. Mitt Romney, the Republican candidate, made a case for a different approach. The president won. And Mr. Romney and the Republicans, not able to persuade the voters of their position, lost. Yet, today, even though Republicans lost a number of winnable Senate seats and have a smaller caucus than in the last Congress, Mitch McConnell, their leader in the Senate, said he would not permit taxes to be raised on anyone. Will the president call his bluff and let all the Bush tax cuts expire - including those on the 99 percent - and then make the case to the country that Republicans insisted that taxes go up for everyone in order to keep the richest one percent from having to pay a higher share?On Medicare, both candidates proposed cutting spending - they even agreed on the amount. But the president, wanting to preserve the program"s value for seniors and others who depend on Medicare, proposed doing it without reducing benefits. Instead, he would save millions by ending the windfall that private insurers earn from the Medicare Advantage program and by reducing payments to some providers. He would also use Medicare policy to stimulate providers of services to find ways to improve the quality of care and keep down the costs. Republicans defined the Medicare problem more simply. They just want to limit federal spending, which they would do by capping it at a fixed amount and distributing those funds to Medicare beneficiaries in the form of vouchers. Then, the beneficiaries would apply the vouchers toward the purchase of coverage in the private health insurance marketplace. The main problem, of course, is that Republicans cannot guarantee that the voucher would cover all the services people need or that it would keep up with the rising cost of insurance. Inevitably, beneficiaries would wind up with less coverage than they have now.It is fair to say that, to the extent that voters focused on policy issues like these, the majority voted for the president"s proposals and rejected those of Governor Romney and his fellow Republicans. So, why doesn"t the election result entitle the president to act on these matters as he said he would? And, to the extent that the Congress must act (e.g., on tax and spending legislation), why doesn"t it leave members of the House and Senate to make adjustments around the edges? Isn"t that what winning means?这是大学作文

楼主写错单词了吧,“lemean”,应该是lsmeans吧? lsmeans命令用来生成最小二乘法下的固定效应. slice后面接固定效应变量,正如其英文含义“薄片,片段”,在lsmeans里面,slice对变量进行分片. 例如lsmeans A*B / slice=B;这句话的意思就是对B变量进行分层,求B每一层下面的A*B变量间交互效应.

你为什么而活？你生命的意义是什么？

C，理由是mean后只能加不定式或ing，而mean to 意味着企图做某事，而ing表示sth，所以C。

“mean”是“arithmetical mean”(数学平均数)，亦即我们日常非学术用时一般人理解的“平均数”。而其他两个“mode”和“mean”，都是可以用来“大概”指示出“大概平均数”的方法，是位置平均数。所以，在统计学的范畴内，“mean”仅指算术平均数，而“average”还包括中位数(Median)和众数(Mode)

be mean with和be mean about的区别为：意思不同、用法不同、侧重点不同。一、意思不同1.be mean with：卑鄙地对待2.be mean about：刻薄二、用法不同1.be mean with：mean用作形容词时的意思是“吝啬的，自私的”，指对属于自己的东西格外的小气，不想让别人得到，或做事情只想到自己，而不替他人着想。mean也可指做事情采取不正当的或有损他人利益的手段，即“卑鄙的，不善良的”，也可指心地不善良，即“刻毒的，邪恶的”。2.be mean about：mean还可指某人或某事处于不高不低(或不长不短)的水平，即“中间的，平均的”。mean引申可指“难看的，劣质的，简陋的”“低劣的，平庸的”“出身微贱的，社会地位低下的”等。三、侧重点不同1.be mean with：侧重于指对象是人。2.be mean about：侧重于指对象是一件事。
