obatain gain acquire 这三个词的区别

obtain,经常表示付出一段时间努力之后"获得"某些东西,譬如说advice,benefits,approval,a degree,information。例句:teenagers have to obtain permission from parents before they go out with friends。(青少年需要获得父母的允许才能够和朋友出外。)gain 强调获得的东西是对你有利或者有帮助的东西,譬如说the access to something,advantage,benefit,control,insight,knowledge,confidence,support,power等等例句:impulse sometimes gains power over nature。(冲动有时候会战胜本性。)acquire 强调通过购买或者强夺的手段去获得一些东西,这些东西一般是可见的,譬如说asset,company,status,title,property;acquire 有时候和gain的意思差不多,可以加skill,knowledge,但是acquire给人的感觉就是获得之后还会长时间占有,所以我自己一般喜欢用acquire skills or knowledge。例句:with thought,practice and feedback,we acquire skills。(有了思考,实践和反馈,我们可以获得技能。)
