to do 与to be done 分别在什么时候使用

"ToBeistoDo"meansthatifyouwanttoBEsomething(anactor,teacher,goodperson)youneedtoDOthethingsittakestobecalledthat(ex.ifyouwanttobeagoodpersonintheeyesofothers,youneedtoDOgoodthings).意思是如果你想成为什么样的人你需要做一些事情证明自己是这样的人这句话常和“TodoistoBe”混淆

to be is to do 按中国的古话说就是：好自为之。 好自为之 意思：http://baike.baidu.com/view/83648.htm基本信息　　成语：好自为之 　　拼音：hǎo zì wéi zhī 　　出处：清·王韬《淞隐漫录·五·四奇人合传》：“此时正大丈夫建功立业之秋，原勿以儿女为念。行矣李君，好自为之。” 　　或读：hào zì wéi zhī 　　出处：《淮南子·本经训》：“君人者不任能，而好自为之，则智日困而自负其责也。” 　　意思：自己认为对的事情就坚持做下去，但是无论什么后果都需要自己去承担。为：干，做。喜欢自己亲手去做。 　　解释：自己妥善地处理，好好地干 　　偏正式；作谓语；用于劝诫人。略带讽刺。 　　你还是好自为之吧。 　　田海燕《吴玉章同志在辛亥革命前后的革命活动》：“至于四川的革命事情，还望四川同志好自为之。” 　　汉语中很有一些词，外表形态上看十分简单，读起来也非常顺嘴，没有丝毫的诘曲聱牙，人们话语中也时不时的脱口而出的用着，可就是禁不得细琢磨，因为琢磨起来也琢磨不出个所以然。比如这个——好自为之。 　　这个词给人一种言说者的凛然不可犯和听话者的冰冷中的犯傻发蒙之感。 　　举例： 　　1、戴上撒旦之星，西山妖姬转身离去，临行前，回首向阿伊达道：“虽说本座很满意这个结局，但是同为女人，本座很是感慨你的选择，你要好自为之了。” 就这样如风似幻、飘缥淡出，转眼消失了踪影。陈近南目送骂道：“死巫婆，什么“好自为之”，你自己才要好自为之哩。”心想：“干！啊，好自为之 是什么意思？”随即，武林群雄纷纷上前道谢，赞扬云丝鹊的仗义相助，至于她的巫婆背景嘛，大家就不再多所计较。 ——神剑王朝 作者：余为魄 　　2、不戒道：“不岐，你、你好——”不岐心头一震，在你好之后，他要说的将是什么呢？心念未已，只听得不戒继续说了下去：“你、你好自为之。”不岐这才松了口气。好自为之，虽然也可以正反两方面解释，但谁会从不好这方面去着想呢？ 　　不戒是掌门人的大弟子，如无意外，当然是他理成单继任掌门。众人都想，因为不戒自知不起，故而吩咐师弟好自为之。这好自为之等于是把掌盲目性理担交托给他的意思。 　　——梁羽生 武当一剑第三回[1]

要成为什么就要去做。

标准答案：活着就是为了奋斗！

tobe是活着的意思。最著名的句子是tobeornottobe,it"saproblem.(生存或死亡，这的确是个问题）todo就是干活，干实事的意思。总体意思是，活着就要干点有意义的事情。苏格拉底（Socrate)说的，意思是付出才有收获...活着就要奋斗...存在即是作为

存在的意义在于奋斗好自为之具体意思看语境

Kurt Vonnegut（康德）说的以下是翻译：“存在”即“动手做” “存在”即“行动” 成功源于实干 存在就是做事 工作是人的存在方式 还有一种，似乎直接源自德语： 我应该，所以我能够。

一切在行动.

要做的是。。。。

因为后面有were

题主的问题涉及一个重要的语法现象，即be+动词不定式（即be+to+Verb结构）可以用来表示按照计划或安排大概率会发生的动作。例如：The shop is to open on next Sunday.那家店将在下周日开业。（除非遇到极特殊情况，否则一定开业）He is to retire next month.他下个月就退休。（除非收到无法拒绝的挽留邀请，肯定会退）注：be going to do也用于表示按计划或安排将要发生的动作，但与be to do比起来发生可能性不一样：前者强调做某事是计划或安排中的事，具体有多大可能发生没说；后者强调除非遇到特殊情况，否则做某事必然发生。He is going to retire naxt month.是说他下个月退休是计划、安排或按规定要发生的事情，并没有说是否一定发生或有多大可能发生。而He is to retire next month.则不仅是说他这个月退休是计划、安排或按规定要发生的事情，而且只要不出意外就肯定会退。

有is 和to be（或者说to be done，被动）是分开的，to be done不定式做表语The task（主） is（系） to be finished（表） by next month.这项工作要在下个月才能完成。

凸后面跟啥

。。。。一个be to do没有啥详解不详解，他本质就是一个表语从句的省略形式，比如I am to go home，就是I am that I will go home。不定式做非谓语动词的本质就是一个助动词加谓语动词在规则上的缩略手法，上一句的will 可以改成should，would，could意思都会不一样，所以就出现了你们需要死记硬背的表将来，表计划，表应该，表什么乱七八糟的。。。

is 和 to be 都是系动词的表达形式 （系动词可以理解为 “是”），只不过时态不同。is 是一般现在时的形式，表示现在的状态或者客观事实，例如 ：Summer is after spring . to be 是将来时，表示将要成为，She is to be a doctor。她将成为医生。 英语里是通过改变动词的形式来表达动作发生的时间的，所以会出现动词的各种形式。建议找专业的老师学习，我朋友出国前在烟台扬格外语学习的，从完全什么都不会，学到雅思考试，效果还挺好的。

it be is to do的中文翻译it be is to do 这是做..双语例句1It must be admitted that it is sometimes quite easy to do so. 应该承认，这两类矛盾有时是容易混淆的。2My credibility is not in question here. So the focus is on where it needs to be whichis what we are trying to do. 我的信誉毋庸置疑。于是人们将注意力放到了应该关注的地方&我们在做的事情。

"Be to be done"是一个被动语态的表达方式，表示某件事情应该被完成或需要被完成。如果要使用主动语态表达相同的意思，通常使用"should do"或"must do"等形式来表示。例如，"The report is to be done by Friday"可以被表达为"Someone should/must do the report by Friday"。在某些情况下，"be to do"也可以用作主动语态，但它通常表示某些安排或计划，例如："I am to do my homework after dinner"（我计划在晚饭后做我的家庭作业）。在这种情况下，它不是"be to be done"的主动语态表达方式。

is 是一个系动词或者助动词，在句中一般充当谓语（复合谓语的一部分），而 to be 明显是一个非谓语结构，在句中不可能充当谓语或者部分谓语。你给出的两个例句中，第一个例句正确，其中 to be self-evident 为宾语补足语（宾语则是 these truths）；第二个例句明显错误，因为即使 these truths... self-evident 可以视为 hold 后的宾语从句，但是is 也不可能作主语 these truths 后面的表语。

to be 句型是指动词不定式中将动词替换成be动词,表作为
