2. So this is a phrase that you can use when you know very little about something, but you’re going to do your best to complete the job.
译文：
1. 约翰正尝试着在浴室里贴上新瓷砖，因为他不愿意付费给装修工去做，他真的是要摸着石头过河了。
2. 当你对某事知道得比较少，但你要自己尽力去完成这项工作，可用这个词组，
【词源】当飞机刚发明不久后，因为飞机上的设备比较简单，飞行员只能通过贴在椅子上的屁股去感觉飞机的飞行状态。于是就有了 “fly by the seat of your pants.”
tiles = 瓷砖
decorator = 装修工
pants = 裤衩
fly by the seat of your pants = 凭着感觉试试，摸着石头过河
口语练习：
This report has to be finished today but no one is here to show me how to do it. I’ll be flying by the seat of my pants, but I’d better try.
