explore, figure out by trial and error, feel around, grope around
最后一次摸索
One last attempt
— 几近成名 (2000)
我伸手绕到纸后面,想换个角度拿着看看,还摸索着找有没有什么盒子。
I reached around behind the paper, wanting to hold it at a different angle and take a look, while feeling around for some kind of box.
开了头三家之后,我才摸索出正确做法。
It wasn’t until I’d opened the first three that I figured out the right way to do it.
非得要我用手去摸索出精神核心在什麽地方吗?
Do I really have to grope around with my hands to figure out where the core lies?
