hook，line，and sinker

milk and honey

pick A's brain

close it up

oil and water

the 64,000 dollar question

make A's toes curl

rear its head

at the top of one's lungs

king's ransom

Tom，Dick，and Harry

take the floor

a bed of roses

get the sack

just the job

keep one's nose clean

pull a rabbit out of the hat

a tough nut

a bitter pill to swallow

grin and bear it

be on about

on the firing line

a bolt from the blue

old chestnut

the man in the moon

pay one's last respects to

bang for the buck

a can of worms

start the ball rolling

a chip off the old block

for kicks

talk a blue streak

a chip on one's shoulder

make a bundle

the whole nine yards

hold all the cards

a dead ringer for

be as good as gold

at one's beck and call

go into a tailspin
