外国人喜欢说的find out，是什么意思？

◇to  find out: (to get information about; to discover; to learn) 了解，发现

例句：
I was unable to find out the name of the man who called.
(我找不出那个打电话来的人的名字。)
Will you please try to find out for me what time that train arrives?
(能否请你替我查查那班火车什么时候到达?)

a. find out 与 find 均可用 that 从句做定语，此时 find out 与 find 均表
“了解，发现”，但 find out 是指“有心去调查而逐渐了解”，而 find 则 多强调“一时的发现”。

例句：
I finally found out that it was John who broke the window.
(我终于查清楚打破窗户的是约翰。)
I find that Peter is pleasant to get along with.
(我发现与彼得相处很愉快。)

b. find out 与 find 亦可用名词或代词做宾语。此时 find out 多表“揭发或查出某真相”，find 则表“找到某物”。

例句:
If you cheat on me, I'll find you out some day.
(如果你对我不忠，总有一天我会把你查个水落石出。)
Did you find your lost wallet?
(你找到你遗失的钱包了吗?)

c. find out 亦可与介词 about 连用，形成下列短语: find out about sth 了解某事
= learn about sth

例句:
When did you find out about Tom's affair?
(你是什么时候知道汤姆的风流韵事的?）
