[译] 你在青年时代就得到这样的人帮助和指导，真是够幸运了。
[误] You are lucky enough to have had the help and guidance of such a man in your youth.

[正] You are fortunate enough to have had the help and guidance of such a man in your youth.
[注] lucky 通常指客观环境有利或由于偶然机会造成的"成功"。例如：You are a lucky fellow. 你真是个幸运儿。fortunate 隐含的意义是由于"命运（fortune）的帮助"，即不取决于人的意志或环境的作用，它也不强调成功本身的偶然性因素。而且 fortunate 是书面语，用于较严肃、较庄重的场合。如：a fortunate voyage（幸运的航行），a fortunate choice of profession（对职业成功的选择）。正句用 fortunate 可增加庄重气氛，较恰当。
