Learning to know学会学习
wet behind the ears
salad days
to knock……into a cocked hat
a cock and bull story
not to make head or tail of it
to rack one's brains
a feather in one's cap
on one's high horse
Leaming to do学会做事
one-two punch
to fly by the seat of one's pants
(right)on the beam
under the rose
a back-seat driver
in apple-pie order
by the skin of one's teeth
let lseeping dogs lie
back to square one
to pull the chestnut out of the fire
an ace in the hole
to paint the lily
to beat about the bush
a baker's dozen
to know the ropes
by hook or by crook
right-hand man
to send coals to Newcastle
to bark up the wrong tree
to cut corners
……
Learning to live together学会团结
Leaming to be学会生存
