gain的详细讲解：
gain表示“获得”时，后可接双宾语。
Her talent and hard work gained her success as an artist.她的天赋和努力使她获得了成功，成为一个艺术家。
earn表示“赚得，赢得”，而gain表示“通过努力而获得有利的东西”。
gain的基本意思是“获得”,指经过努力或竞争而取得有价值或想要的东西,如成就、经验、荣誉等。引申可表示“增加”“增进”“到达”“(钟表)走快…分钟”等。gain还可表示“抵达”。
gain可用作及物动词,也可用作不及物动词。用作及物动词时接名词或代词作宾语。gain作“获得”解时也可接双宾语。
gain用作不及物动词时后接介词in表示“在某方面有所增长”; 后接介词on或upon表示“接近,胜过或赶上”。
gain作“盈利”解时是不可数名词,表示抽象意义。gain表示具体的数量、力量等的“增加,增进”“利润”时是可数名词,常可用复数形式。
gain, achieve, acquire, attain, earn, get, obtain, secure, win
这组词的共同意思是“取得; 获得”。其区别是：
1.除secure是正式用词外,其余各词均为一般用词。
2.achieve主要指取得成功、成就或实现预期目的; acquire主要指逐渐获得知识、能力、荣誉等; attain主要指达到重要目标或获得珍贵的东西; earn凭借功劳赚得或获得工资、报酬、荣誉、赞赏等; gain主要指获得或赢得有一定价值的东西; get指以各种方式获得各种所需或不需之物; obtain指获得所需之物或达到预期目的; secure指得到渴望或竞争性的东西; win指在竞争、比赛、争论或战斗中击败对手而赢得胜利或获得人们的爱戴〔好感〕等。
3.achieve指克服困难之后而获得; acquire, attain, earn指通过努力而获得; gain指通过巨大努力而获得; obtain多指通过长期努力而获得,有时也指无须经过努力; 其他各词不强调通过努力与否; get可指通过各种方式获得; earn还指凭借功劳而赚得; win还指通过作出优异成绩而赢得。
4.achieve强调结果; acquire强调量的增加; attain含有达到完美地步的意味; gain强调所获得之物能够造成的优势; obtain强调愿望得到满足; secure强调有把握或成功地获得。
5.get是这组同义词中的最常用词,可指主动争取,也可指被动接受,有时不一定需要很大努力就能获得; acquire指持续,慢慢地获得,强调过程; 而earn, gain都强调经过艰苦努力而获得的这一结果, gain比obtain所付出的努力还要大些; win则指在竞赛中或战斗中赢得或获得胜利,可以通过努力获得,也可以偶然获得。例如:
He did not get what he had earned?他未获得他应得到的东西。
The ability to use a language can be acquired by the act of using the language.运用语言的能力,只能通过不断练习才能获得。
She gained rich experience in teaching.她获得了丰富的教学经验。
I've got your telegram.我已经收到了你的电报。
We wished to obtain first-hand information.我们要能得到第一手情报就好了。
Industry won him his success.勤奋使他获得了成功。
6.acquire的宾语多为知识、技能等; earn的宾语多为金钱、荣誉等理应得到的东西; obtain的宾语多为期望已久的东西; gain的宾语多为经验、利益、优势、好处等; 而win的宾语则为比赛、战斗等; get的宾语则比较广泛,即既可以是具体的东西,也可以是抽象的事物。例如:
He got what he had earned.他获得了他应得到的东西。
You must work hard to acquire good knowledge of English.你要用功,以便精通英语。
Our firm has gained a good reputation.我们公司赢得了好名声。
Then I'll go and get you a chair.我去给你拿把椅子来。
At last, he obtained his father's pardon.他终于得到了父亲的原谅。
They won the basketball match.他们打赢了这场篮球赛。
7.这组动词都可跟简单宾语。get, earn, gain, obtain, secure和win可跟双宾语; secure还可跟wh-从句; win还可跟含不定式的复合宾语。此外, gain和win有时还可用作不及物动词。acquire和attain常跟抽象名词。
8.attain常用于庄重场合。win语气比gain强。
这些动词均含“获得、取得、得到”之意。
:acquire强调通过不断的、持续的努力而获得某物，也指日积月累地渐渐地获得。书面语用词。
:obtain较正式用词，着重通过巨大努力、要求而得到所需或盼望已久的东西。
:gain侧重指经过努力或有意识行动而取得某种成就或获得某种利益或好处。
:get普通用词，使用广泛，可指以任何方式得到某物，也不一定要经过努力。
:win主要指通过努力、斗争、比赛等而获得胜利。
:earn侧重指依靠自己的劳动或因付出代价与有功而获得。
:secure强调要通过努力或竞争，或需要付出代价才能获得所渴望的东西。
这些名词均有“利益、好处”之意。
:advantage指因某方面占优势或利用某机会以及对方弱点而获得利益与好处。
:benefit普通用词，指通过正当手段从物质或精神方面得到的任何好处或利益。
:interest作“利益”解时，多用复数形式，既可指集团、群体的利益，又可指个人的利益。
:favour指在竞争中获得的advantage,也可指狭隘的个人利益。
:profit着重收益，尤指从物质、钱财等方面获得的利益。
:gain指获得的物质利益，也暗示不损坏他人利益而得的无形好处。
错句举例与错句分析
错句：he gained excellent sums of money by acting.
纠正：he gained excellent sums of money by acting.
翻译：通过表演，他赚了不少钱。
分析：earn表示“赚得，赢得”，而gain表示“通过努力而获得有利的东西”。这里赚钱用earn。
☆ 15世纪晚期进入英语，直接源自中古法语的中古法；最初源自古法语的gaaigne，意为获取，优势。
