When should you say took and when should you say take?

Answer 1

when to use took, take and taken are things that I learnt when I was learning the language as a child by hearing it being spoken properly.

I think you just have to emerce yourself in the language to learn these sorts of often irregular details.

Answer 2

"Take" is the present tense, and "took" is the past tense of the verb "to take." Use "take" for present actions (e.g., I take the bus every morning) and "took" for past actions (e.g., I took the bus yesterday).
