Hello Shinhye Lee,
Maybe I can help you.
------------------------------------------
"He managed to climb up a tree."
It means like 'trying to'?
Then what is the difference?
"Trying to" means he made an effort and did not succeed. He didn't get up the tree.
"Managed to" means he made it up the tree successfully!
Any example of conjugation of the verb would be appreciated!
Present simple-------------------------
I manage to eat rice every day.
You manage to breathe air daily.
He manages to live life day by day.
They manage....
We manage....
Past------------
I, you, he/she/it, we, they, managed to eat rice yesterday.
Future ------------
I/you/he/she/it/they/we will manage to do it tomorrow.
Present continuous------------
I am managing to do that right now. (at this moment).
------------------------------------------------
This is just some help, and I will allow you to look up the entire conjugation when you can. Best to use it when you can as well!
Good question! Keep on learning English!
Regards,
David
