attain achieve acquire

attain achieve acquire
有什么区别
（在用于经过长时间努力时)
after working for the firm for ten years,he finally _ the rank of deputy director
为什么不能填后两个呢

attain 正式用语,指经过艰苦努力才使人达到完美境地
achieve 强调由于极大的努力,克服困难后达到目标
acquire 指经过不懈努力才获得的技术,知识等抽象的东西,也指养成习惯等
给你几道题,用在句子中区分他们比较含义：
1.After so many years of hard work,he finally ___ success.（achieved）
2.She has ___ some very unpleasant habits recently0.（acquired）
3.In typhoon,winds ___ a speed greater than 120 km per hour.（attain）
希望你能区别清楚了.^^
