come about和 happen用法的区别

看后面的副词啦.come about多作不可避免之意,多用于疑问句.Can you tell me how the accidents come about?你能告诉我事故是怎样发生的吗?
而come up有某事浮上水面之意,up嘛.出现嘛.

在牛津高阶上,COME ABOUT的英译是HAPPER(发生),COME UP的英译是ARISE,OCCUR(出现,发生).主要的是COME ABOUT后面还可以接从句.

1、你能告诉我争吵是如何发生的吗?（come about）
Could you tell me how quarrels come about?
2、虽然她有许多缺点,但我们都很喜欢她.（be fond of）
Although she has many mistakes,we are fond of her very much.
3、我不关心价钱,只要车好用就行了.（care about）
I don't care about the price,it just all right if the car drives well.

1 How did it come about that she was late about two hours for that short distance?
2 Some students subscribe to the idea that if they were not to the major universities, they would not find a job in the future.
3 Under no circumstances can he give in.
4 I am grateful to you on behalf of our whole class.
5 There was small disagreement, but we get along with the negotiation on the whole.
6 mostly the boys

单词的用法最好是放在句子里理解.
我觉得,学语言最好多读句子和文章,句子记得了,单词的用法顺其自然就大致清楚了.
如果一个一个词去理解,费时又不好记.
建议你把涉及这些词语的文章和段落读熟甚至背熟,别的文章也多看看,往往会有触类旁通的感觉.（就像我们小朋友学说“打字,打人,打电话,打酱油”,也不用专门去学“打”这个字的用法一样.
这是本人学语言的一点心得,仅供参考,

come across
v.
来到,偶遇,给人印象深刻
不期而遇,交付
happen
[5hApEn]
vi.
发生,碰巧,偶然
v.
发生,恰巧,偶然发现

come about
发生,产生,实现；【航海】抢风调向,改变方向
How did it come about that he knew where we were?
x09x09x09x09x09x09他是怎么知道我们在什麽地方的呢?
Expected or required but not yet having come about.
x09x09x09x09x09x09期待发生的被期望或要求但仍未发生的
How did this come about?
x09x09x09x09x09x09这是怎么发生的?

两个都做“发生”用的时候是没什么区别的.
只是come about还有“ 改变方向”的意思
不是的,得看具体句子.
How did this come about?这事是怎么发生的?
中this已经是主语,就不会用what.
what happened?中what就是主语.
你说Tell me what came about.也行的.
how can this happened?这怎么可能发生了?也行的.
(1)take place 一般指非偶然性事件的“发生”,即这种事件的发生一定有某种原因或事先的安排,例如：
Great changes have taken place in our hometown during the past ten years.

这些词或短语都有“发生”的意思,但用法各不相同,区别如下：
(1). take place 表示“发生、举行、举办”,一般指非偶然性事件的“发生”,即这种事件的发生一定有某种原因或事先的安排,例如：
Great changes have taken place in our hometown during the past ten years.
The Olympic Games of 2008 will take place in Beijing.

你的题
They used to be good friends but now they are like strangers.How( )this( A.did;come about B.did;happen to C.was;ended up D.was;happened
他们曾经是很好的朋友,但是现在像陌生人一样.这是怎么发生的?
如果要选B的话,应该是How did this happen?
C选项,end up是结束,不符合语境.D选项,happen是实义动词,提问是应该用did而不是was.
in total总计,合计 用在句首或句尾 on total 这个词组是没有的.a total of 也是总计,后面要加名词的.

没有限制什么句式,疑问句、陈述句等都可以
它有两个意思
1．船舶或风向的转变,转身,回转
It was so stormy that the ship had to come about and head for the harbour．风浪太大,船不得不调转航向,朝港口驶去.
2．发生,发现,领悟
How did it come about that the man is dismissed?那个人被解雇了,怎么回事?

这四个都没有被动,确定.
你问题里的The war broke out between the two countries,这里的broke不是
被动哦,broke 是break的过去式.在这里是表示过去的.不是被动啦 ``

take place,happen,occur,come about和break out用法区别
这些词或短语都有“发生”的意思,但用法各不相同,区别如下：
(1).take place 表示“发生、举行、举办”,一般指非偶然性事件的“发生”,即这种事件的发生一定有某种原因或事先的安排,例如：
Great changes have taken place in our hometown during the past ten years.
The Olympic Games of 2008 will take place in Beijing.
(2) .happen作“发生、碰巧”解,一般用于偶然或突发性事件,例如：
What happened to you?(一般不说：What did you happen?)
Maybe something unexpected happened.
I happened to see him on my way home.
= It happened that I saw him on my way home.
(3).occur作“发生、想到、突然想起”解,其意义相当于happen,例如：
What has occurred?(=What has happened?)
A big earthquake occurred (=happened) in the south of China last month.
It occurred to me that she didn’t know I had moved into the new house.
(4).come about表示“发生、产生”,多指事情已经发生了,但还不知道为什么,常用于疑问句和否定句,例如：
When Mother woke up,she didn’t know what had come about.
I’ll never understand how it came about that you were late three times a week.
Do you know how the air accident came about?
(5).break out意思为“发生、爆发”,常指战争、灾难、疾病或者争吵等事件的发生,也可以表示突然大声叫喊等,例如：
Two world wars broke out last century.
A fire broke out in the hospital in the mid-night.
After the flood,diseases broke out here and there.
She broke out,“That is too unfair!”

如果是在直接引语里面的句子,那就是“历史现在时”,即用现在是描述过去的事情,表达对当时时间生动深刻地呈现.如果不是的话,要么用“how does the accident come about?” 或”how did the accident come about?”,在一个就是,过去式变一般疑问句时,不是系动词的,要加助动词,且原来的动词变为原型

come about表示“发生、产生”,多指事情已经发生了,但还不知道为什么,常用于疑问句和否定句,例如：
When Mother woke up,she didn’t know what had come about.
I’ll never understand how it came about that you were late three times a week.
Do you know how the air accident came about?

按照所给句子语境,应该用bring about.
bring about 造成,引起[导致]（某事）；创造；实现
To bring something about means to cause it to happen.
【经常可以指代“引起或导致不良后果”,但是也可以指代正常的后果或预期的结果】,是【及物动词短语】.
They conspired to bring about the meeting of the two people.
他们共同促成了两人的会面.
Several circumstances concurred to bring about the result.
几种情况合在一起导致了这个结局.
come about产生;发生
When you say how or when somethingcame about,you say how or when it happened.
仅用于陈述【正常的发生、产生】,是【不及物动词短语】.
That came about when we went to Glastonbury last year...
那是我们去年去格拉斯顿伯里的时候发生的事.
祝你开心如意!
