try google, make at least a small effort

cost an arm and a leg
work my fingers to the bone
keep my chin up
pull his socks up
go the extra mile
raise a finger
doing things by halves
knowing beans about it
make a meal
make a meal of it
go all out
cut corners
break your back
go through thick and thin
have one foot in the grave
jumps through hoops

please, explain to me about these idioms

cost an arm and a leg = expensive
work my fingers to the bone = to work very hard (with a lot of effort)
keep my chin up = continue to be happy
pull his socks up = stop being lazy
go the extra mile = do more than is asked
not raise a finger = to do nothing, particularly when someone else is working
doing things by halves = 
knowing beans about it = never heard of this!
make a meal of something = to make an easy job difficult
make a meal of it
go all out = 100% effort
cut corners = do something incompletely to save time
break your back = work too hard
go through thick and thin = to stay loyal when things are good and when they are bad too
have one foot in the grave = close to death, not used in serious contexts
jumps through hoops = do as you are commanded by the boss (who is demanding unreasonable things)

Hope that helps
