口語教室第1期:Take stock of

Well, if you look up the dictionary, the first meaning of stock is the supply of things you keep and can use when you need them.
如果查字典的話呢,stock的意思就是(商店的)現貨,存貨,庫存

But here, to take stock of sth is you to think carefully about it, before taking action accordingly.
而take stock of sth的意思,就是對某情況加以總結,作出評估,進行反思
