smart alec

how much longer will it be before some smart alec from the building trade decides to replace conventional windows with electronic displays?

但在建筑业那些自作聪明的人将传统的窗户改装成电子显示屏之前，人们抬头看世界的时间会有多长？

unfortunately for you, smart-alec, i got the data.

很不幸，自作聪明的家伙，我找到了有关的数据。

he keeps telling the instructor what to do - the smart alec.

他老是命令教员怎么做——一个自以为了不起的家伙。

You'll end up no more than a smart alec and you're well down that road already.

你最终只会变得自命不凡，而且你现在已经很有些自以为是了。

this is where i say something that a smart-alec at a party would no doubt disagree with, and then i triumph by having data to back it up.

我要说的话无疑会遭到在派对上自作聪明的人的反对。但我最终会胜利的，因为我有数据支持。
