hehe,you r so lovely.
the most directly translation is 扔,almost equal throw in english.
but there are tender differences between 丟,投,摔,拋,扔.
扔=throw
丢= throw away, ep:丢垃圾(throw the rubbish, drop litter)
投, throw something to a point or circle, ep:投篮(shoot,throw the basketball to the basketry )
摔,throw something to the ground
抛,throw out/away,usually make a parabola
as you know chinese is exquisite, it the best way to master it is reading more and trying remember,only analysis can do little help.
read and talk,you will improve fast. :)
