1、Howcome为什么；怎么会?（那样）。用法大部分就等于why，但是它的用法没有像why那么广,它通常是用在你觉得奇怪,而问为什么的时候。2、例如：有人早上一大早要去supermarket,你就会问他，Howcome?另外,当别人问你一个问题,而你不想回答时可以说Howcome?相当于Whydoyouaskthat?也就是说Itsnoneofyourbusiness!

how come的意思就是有一种，“为什么？”，“怎么回事？”，“怎么会这样呢？”How come它的用法可以等同于why，但又不像why那么广泛被使用,How come通常用在日常口语中，没有why那么正式。另外，how come跟why虽然用法上差不多，但二者问法不同。how come后面可以接内容，也可以不接内容，How come主要是指做某事或某事发生的方式或方法，还可以引导从句或动词不定式，在句中作宾语。比如说，有人早上一大早要去supermarket，你就会问他，How come。Why is our oven broken?换成how come的话，要说成，How come our oven is broken?例句：1、How come you are so pretty?你为什么这么好看？2、How come she is always late?怎么她总是迟到？

"How come" 和 "why" 都是用于询问原因或解释的疑问词，但它们之间有一些区别。"How come" 通常用于口语中，意为 "为什么" 或 "怎么回事"，通常暗示对某些情况或事件感到惊讶或不理解。 "How come" 通常用于简短的对话中，例如：How come you"re late?（你为什么迟到了？）How come you didn"t tell me about the party?（你为什么不告诉我这个派对？）"Why" 更正式，也可以用于口语和书面语中，通常用于提出一个问题并寻求解释或理由。 "Why" 通常用于更长的问句和正式的场合中，例如：Why did you decide to change jobs?（你为什么决定换工作？）Why is it important to exercise regularly?（为什么定期锻炼很重要？）因此，尽管 "How come" 和 "why" 都用于询问原因或解释，但它们的用法和语气略有不同。 "How come" 更加口语化和日常化，而 "why" 则更加正式和适用于各种场合

这是口语句型，一般翻译为：怎么会

how come 英[hau ku028cm] 美[hau028a ku028cm] [词典] 为什么，怎么会…（那样）; [例句]"How come we never know what"s going on?" he groused“为什么我们对正在发生的事情总是一无所知？”他抱怨说。

how come? adv. 怎么会...?, 为什么...?

how come 和why的区别为：指代不同、语法不同、侧重点不同。一、指代不同1、how come：怎么会。2、why：为什么。二、语法不同1、how come：how作“多么,多少”解时,指达到什么程度,到何种地步,后接形容词或副词。how还常用于感叹句中,可修饰谓语动词,在句中作状语,表示程度,意为“多么,何等”。2、why：why的意思是“为什么”,可用作疑问副词,也用作关系副词,还用作连接副词,可以引导名词从句。三、侧重点不同1、how come：是一个词组。2、why：是一个单词。

一个意思！

How come为什么会…..? 表示要求对所发生的事情说明理由或做出解释Why可能更直接点，就是原因。比如说：一个人迟到了，你问他为什么，如果用How come 可能是想知道发生了什么，具体原因，而不带有指责的意思。Why 会更直接点。当然这两个问法意思都是差不多的，只是可以在语气上做区分。

1.我设法用想要对待母亲的方式对待我的乘客. 2.造句： （1）How come you"re so late? 你怎么会来得这么迟? （2）How come you start again 你怎么又抽起来了? （3）How come I wasn"t told? 我怎么没有听说? （4）How come are you late? 你为什么来晚了? （5）How come you started again? 你怎么又抽起来了. （6）How come you eat so little? 你怎么吃得这么少? （7）How come she has descended to stealing? 她怎么会堕落到偷窃的? （8）Steve：For the most part.How come? 史提夫：一般都有空.怎么这么问?

为什么

意思不同、用法不同、侧重点不同。How come意思：为什么；怎么会…（那样）。why意思：(用于问句)为什么，为何，(反问，表示不必)何必，(说明理由)为什么，…的原因。 how come 和why的区别 用法不同 1.How come用法：作感叹词时，主要表示吃惊、承认、认可，如果对方提的问题过于简单，回答时可以用来表示轻微的惊异，有时用来表示不耐烦、抗议或异议。 2.why用法：why的意思是“为什么”，可用作疑问副词，也用作关系副词，还用作连接副词，可以引导名词从句。why作为疑问副词，引导特殊疑问句或省略的特殊疑问句，表示疑问，意思是“为什么”，后面跟不带to的动词不定式，意思是“为什么要…”，表示某一动作是不必要的或无意义的。 侧重点不同 1.How come侧重点：侧重于口语用法，不在书面语中出现。 2.why侧重点：侧重于万能的问原因，什么时候都可以用。 HOW的用法 副词 ad. 1.(指方式、方法)怎样,怎么 How did you climb to the top of that building? 你是如何爬上楼顶的? 2.(指健康等情况)怎样 How is Mrs. Smith? 史密斯太太身体好吗? 3.(指数量、程度)多少 How many students are there in your class? 你班里有多少学生? 4.(表感叹)多么 How I wish to have a long vacation these days! 这些天我多么希望去度一次长假啊! 5.(通常于can连用)(表理由)为何 How can you do such a thing to her? 你怎么能对她做出这种事来? 连接词 conj. 1.(用于间接陈述中,意义和作用与that相仿) This is how we became acquainted. 我们就是这样认识的。 2.【口】=however 名词 n. 1.方法,做法[the S] The book tells you about the how and the why of flight. 这本书告诉你飞行的方法和原理。

1 不用。 how come 后直接+陈述句 .How come you have never mentioned that before.？ How come i didnt know？2 第一种表述是对的。Is he not coming？Can you not do it？

how comeAdverb，副词：question word;疑问词 what is the reason (`how come" is a nonstandard variant); "why are you here?"; "how come he got an ice cream cone but I didn"t?"同义词：why 例句：How come he got the job? 怎么他会得到这个职位呢?用法：相当于why,后面接完整的句子。例句：How come you don"t call me anymore? 你怎么不再给我打电话了？注意：下面是动名词做主语的句子，而不是动名词直接接在how come 之后。 How come drinking too much coffee is bad? 喝太多咖啡怎么会不好？how come 后面除了接完整的句子之外，表示对这一句子陈述的事实表示质疑外，一般不能连接其他的语法结构。

How come 是一种口语固定表达，尤其是美国人喜欢用，意思等同Why（为什么）。正由于是固定表达，所以它没有时态的变化。

How come we dont even talk no more, and you dont even call no more. We dont barely keep in touch at all, and I dont even feel the same love when we hug no more. And I heard it through the grape vine we even beefin now. After all the years we been down, aint no way no how, this bullshit can"t be true. We family and aint a damn thing changed, unless it"s you [Eminem] So young, so full of life in vibrant, side by side wherever you was ridin" I went. So close, almost on some Bonnie & Clyde shit. When Ronnie died you was right by my side with a shoulder to cry on, tissue to wipe my eyes, and a bucket to catch every tear I cried inside it. You even had the same type of childhood I did. Sometimes I just want to know why is it that you surcame to yours and mine I survived it. You ran the streets, I 9 to 5"d it. We grew up, grew apart, as time went by us, then I blew up to both yours and mine surprises. Now I feel a vibe I just cant describe it, as much as your pride tries to hide it. Your cold, your touch it"s just like ice in your eyes is the look of resenment I can sense it, and I dont like it. [Chorus] [Kon Artis] It was my dream at first to be on spittin" a verse on my own album with a deal but shit got worse. So I came out, I woulda killed a nigga first before I let him disrespect me and check me over some worst. Some bitch that I wasn"t with, I would hit her then quit. But you would pull a talk with her and tell her she was the shit. I told you dont get involved in it, you was smokin the chron with her comin" out of the bar with her stumblin half drunk like y"all was husband and wife or somethin". But me catchin" you fuckin" other niggers musta hurt your pride or somethin" cause you won"t fuck at the mouth with people like you wanted with me, when all I tried to do was show you that your bitch was shifty. And ever since the fans and all the shit that I produced, you actin" like I ain"t your man and lyin" like she can"t be loose. But I am really your friend, I"m just tryin" to tell you the truth, but dont hate the game or the player cause the one that"s changing is you. [Chorus] [Proof] You"re only at the top cause my homie had to stop, now we actin" like I gotta live only for the block. And homies in the hood, only she be on the tube, only gossip on the porch, get to speakin" on who. Fools I used to rap with all expect magic like my finger get to snappin" and *poof* it just happen. But Proof is just actin out the party was stoned, Shady made it so my babys ain"t starvin" at home. See the devil in you grin, since the ghetto we been friends, whenever real intelligence thats forever till the end. I be the hatred in your eyes and the satan in your lives and wastin" my times with these snakes in disguise. (How come) when you talk it"s with bitter and spite, and (How come) it"s my fault for what you did with your life and everytime I go to hear you and play you look away. We barely embrace, you can"t even look me in my face. [Chorus]

接句子.how come 原来是 how does it come that .....

how come可以单独成句How come 的用法大部分就等于 why ，但是它的用法没有像 why 那么广, 它通常是用在你觉得奇怪, 而问为什么的时候。例如：有人早上一大早要去 supermarket,你就会问他，"How come?" 另外, 当别人问你一个问题, 而你不想回答时可以说 "How come?" 相当于"Why do you ask that?" 也就是说 "It"s none ofyour business! "虽然 how come 跟 why 的用法上差不多, 但二者的问法不同。
