in the beginning与at the beginning有什么区别？

开始，表示时间，在开始的时候

begin是动词，意思是“开始”，在句中是作谓语用的； in the beginning是介词短语， 意思是“起初，刚开始”，在介词短语中，动词begin要改用其动名词形式，即beginning，才能作介词宾语，beginning不是进行时，是begin的动名词形式。

beginning是begin的动名词形式，所以in the beginning是在开始的时候的意思。in the beginning一般置于句首。

简单说，前者直接单独使用即可，后者接of介词使用。

at the beginning 与in the beginning 在用法上由一些区别.in the beginning 通常单独用作时间状语或定语,而较少和of短语连用,意为“起初；在开始的时候”,暗含着后来又变化的意思.如：In the beginning we thought we"d better get it all arranged.在开始的时候,我们以为不会把它全安排好.You will find it rather difficult in the beginning.你会发现它在开始的时候是相当难的.In the beginning I felt very lonesome in London.起初,我在伦敦觉得非常孤独.at the beginning 常常跟of短语连用,如果后面没有跟of短语,则大都可以从上下文看出来.如：At the beginning of this century a great many Europeans went to live in the USA.本世纪初许多欧洲人去美国居住.2.Start at the beginning and read until you get to the bottom of Page Thirteen.从第13页开头开始读,一直读到第13页末尾.应当注意,at the beginning 在单独使用时,有时与in the beginning 同义.如：He disliked it at / in the beginning.At the beginning he wasn"t interested in it.

区别：in the beginning 意为“开始时”；at the beginning不能单独用，它后面须加of，意思为“在开始…时候”： 1、At the beginning of the meeting，he didn′t say anything；but at the end of the meeting，he said a lot. 2、In the beginning，he sang a song；but in the end，he gave a speech on how to make friends.

同样的“at the beginning”和“in the beginning”有什么区别？其实也很简单哦！At the end VS In the end虽然两个词组的意思都是表达最终。但是最明显的区别就是at the end，后面是可以加一个of的。英语例句：① He left us at the end of the trip.他在旅程的最后，离开了我们。② You need to take an exam at the end of each lesson.每节课的最后，你都需要参加考试。* 你可以说at the end of time某个时间的最后，at the end of the book某本书，某个章节的最后，也可以说at the end of the driveway车道，路的尽头等。那in the end表达的意思就是finally（最终地），它一般用于修饰整个句子，他后面绝对不能加一个of！绝对不能加！① In the end, he was asked to clear his desk.最终，他被要求卷铺盖走人。② Don"t worry, everything will be okay in the end.不要担心，最终一切都会变好的。At the beginning VS In the beginning同样的道理，at the beginning可以加一个of在它后面，表示某个事情或者某个时间的开始。英语例句：① at the beginning of the week/story/movie/game, etc.在这周/故事/电影/游戏等的开始。但是当我们说到in the beginning，只能表示最初地，用于修饰整个句子，不能加of。英语例句：① Love is sweet in the beginning, but bitter in the end.爱情开始时是甜的，但最后是苦的。② In the beginning, I was full of anger!最开始的时候，我充满了愤怒！好了，这就是我们at the end和in the end以及at the beginning和in the beginning的区别，可千万别记混淆了。

intheendof:intheend后面不能加of，表示最后，比如说一件事的最后等。　　与之相关的短语有ontheendof、attheendof。attheendof在时间或地点的尽头，是指的时间比较确切的时间点；ontheendof表示在某个物品的端头，不如说在桌子的另一端头。例如：　　1、Atthebeginning"impliesareferencetoamorespecificpointintime,whereas"inthebeginning"impliessomethingoccuringoveraslightlylongerperiodoftime.　　2、Atthebeginning(of)isusedforthetimeandplacewhensomethingbegins.Inthebeginning(=atfirst)suggestsacontrastwithalatersituation.　　3、Inthebeginninggodcreatedman.

不一样。atthebeginning和inthebeginning所表达的语义有所不同。英语介词at和in在用于时间表达时，at为时间点，in为时间段。依据这一基本词义，atthebeginning表达的是一个在开始时的时间点，即以某一活动或情景作为开场的标志，如开场白、开幕音乐等；inthebeginning则表达开始后正式活动的时间段，如会议首先讨论的议题、演出开场后的第一个节目等。就内容而言，在很多情况下，inthebeginning用来表达事情或活动的第一段安排，属于事情或活动的一部分；而atthebeginning发生的事则不一定是活动的一部分。更多的例句：Atthebeginningoftheworld,therewasnothingbutwater.（世界开始时只有水的存在）Atthebeginningoftheterm,thenumberonepriorityistomakesureyouknowaboutyourteacher.（学期开始时就应该了解上课的老师）Inthebeginning,wewilldiscussifitisreallynecessarytodevelopanewproduct.（讨论的第一个内容）Inthebeginningeverybodyputtheirmoneyintointernetenterprises.（刚开始投资阶段的现象）

in the beginning （开始时）要单独使用 at the beginning 不能单独使用，要与 of 连用，即at the beginning of(在……之初)e.g. at the beginning of this month(本月初)

　　in the end of : in the end后面不能加of，表示最后，比如说一件事的最后等。　　与之相关的短语有on the end of、at the end of。at the end of在时间或地点的尽头 ，是指的时间比较确切的时间点；on the end of表示在某个物品的端头，不如说在桌子的另一端头。例如：　　1、At the beginning" implies a reference to a more specific point in time, where as "in the beginning" implies something occuring over a slightly longer period of time.　　2、At the beginning (of) is used for the time and place when something begins. In the beginning (= at first) suggests a contrast with a later situation.　　3、In the beginning god created man.

In the beginning，some of us took no interest in physics． 起初我们有些人对物理不感兴趣。

前面的加of！后面三个没有区别的，都是首先的意思

作为句首的话，后面是要加逗号的，如果是xxxxxxxxxxx in the beginning，那xxxxx和in之间不用加逗号

at start

at the begining

"at the beginning" implies a reference to a more specific point in time,where as "in the beginning" implies something occuring over a slightly longer period of time.They are often interchangeable,though. At.是指的时间比较确切的时间点,In.指的时间稍长,但是一般能互换. At the beginning (of) is used for the time and place when something begins.In the beginning (= at first) suggests a contrast with a later situation At.指的是事情开始的时间和地点,In .（= at first 一开始）一般会有一个稍后的对比. 例句： I would like to start with.lets start at the beginning In the beginning god created man

不能，因为正常语序下这个句子应该是Thewordisinthebeginning.所以，其实主语是theword

固定词组。

做任务

on Sunday, on April 1st, on the first day,具体在哪一天用ON

前者意思是开头，开端，开始部分，句型有at the beginning of sth，后者等于at first，指开始的时间和起点。

at the beginning与in the beginning是一样的。可以互换的。求个采纳，谢谢你了哦

at the beginning与in the beginning在用法上有一些区别。in the beginning通常单独用作时间状语或定语，而较少跟of短语连用，其意义为：“起初”、“在开始的时候”，暗含着后来有变化的意思。如：　　1. In the beginning we thought we"d never get it all arranged. 在开始的时候，我们以为不会把它全安排好。　　2. In the beginning I felt very lonesome in London. 起初，我在伦敦觉得非常孤独。at the beginning常常跟of短语连用（如of the week, of the year, of the book等），如果后面没有跟of短语，则大都可以从上下文看出来。如：　　1. At the beginning of this century a great many Europeans went to live in the USA. 本世纪初许多欧洲人去美国居住。　　2. Start at the beginning and read until you get to the bottom of Page Five. 从第5页开头开始读，一直读到第5页末尾。注意：at the beginning 在单独使用时，有时与in the beginning同义。如：　　1. He disliked it at / in the beginning. 起初，他并不喜欢它。　　2. At / In the beginning he wasn"t interested in it. 开始，他并不感兴趣。

不一样。at the beginning 和 in the beginning 所表达的语义有所不同。英语介词 at 和 in 在用于时间表达时，at 为时间点，in 为时间段。依据这一基本词义，at the beginning 表达的是一个在开始时的时间点，即以某一活动或情景作为开场的标志，如开场白、开幕音乐等；in the beginning 则表达开始后正式活动的时间段，如会议首先讨论的议题、演出开场后的第一个节目等。就内容而言，在很多情况下，in the beginning 用来表达事情或活动的第一段安排，属于事情或活动的一部分；而 at the beginning 发生的事则不一定是活动的一部分。更多的例句：At the beginning of the world, there was nothing but water. （世界开始时只有水的存在）At the beginning of the term, the number one priority is to make sure you know about your teacher. （学期开始时就应该了解上课的老师）In the beginning, we will discuss if it is really necessary to develop a new product. （讨论的第一个内容）In the beginning everybody put their money into internet enterprises. （刚开始投资阶段的现象）

楼上恰好说反了意思：at the beginning,是时间：起初，开始 in the beginning 是具体: 初始部分用法: in the beginning 用of

first of all 表示“首先，第一”，相当于first。比如：First of all, allow me to extend to you my warmest welcome.首先，请允许我向你们表达我最热烈的欢迎。First of all, you should hold an organizing committee meeting.首先，我们应该召开一个组织委员会会议。at first 表示“起初，起先，首先”的意思，比如：At first, bartering took place as an exchange between two people.起初，物物交换是发生在两个人之间的交易in the beginning 表示“开始，开端，起初”，后面通常接介词of，比如：In the beginning, the universe was a void full of energy but without form.太初之际，整个宇宙一片混沌，只有能量。In the beginning of the class, the teacher questioned us on verbs.上课开始的时候，老师提问我们动词的用法。

first of all 首先，首要 强调重要性，at first 起初， 一般用于叙事口气in the beginning 开始时，开端时，一般讲at the beginning of sth. in the beginning貌似用得不怎么多

firstofall表示“首先，第一”，相当于first。比如： Firstofall,allowmetoextendtoyoumywarmestwelcome. 首先，请允许我向你们表达我最热烈的欢迎。 Firstofall,youshouldholdanorganizingcommitteemeeting. 首先，我们应该召开一个组织委员会会议。 atfirst表示“起初，起先，首先”的意思，比如： Atfirst,barteringtookplaceasanexchangebetweentwopeople. 起初，物物交换是发生在两个人之间的交易 inthebeginning表示“开始，开端，起初”，后面通常接介词of，比如： Inthebeginning,theuniversewasavoidfullofenergybutwithoutform. 太初之际，整个宇宙一片混沌，只有能量。 Inthebeginningoftheclass,theteacherquestionedusonverbs. 上课开始的时候，老师提问我们动词的用法。 祝你学习进步，更上一层楼！请记得采纳，谢谢！(*^__^*)

atthebeginningof意思是：在......开始阶段没有atthebeginof这个形式，这个形式是错误的希望能帮到你，祝更上一层楼o(∩_∩)o有不会的欢迎再继续问我(*^__^*)

应该是atthebeginningof；inthebeginning是一个介词短语，一般置于句首相当于一个副词，它不加of

用法不同、使用搭配不同、适用范围不同。at the end of多用于时间(如星期、年月、学期、季节等)或地点。而in the end of多用于某件事情,即“最后,终于,到头来”。
