a gleam of hope

Haste makes waste.

Bully the weak

repay injury with kindness

have a good command of through diligent study

with regularity and throughness

speech devoid of substance

with the sword of Damocles above one's head

utterly worthless

set the tune with one beat of the gong(give the final word)

flat country(wide expanse of flat land)

an eye for an eye(retaliationof an equal ferocity)

to be close friends

one side of the matter

have a beginning but no end(leave something half done)

записывать всё，что слышишь

The moon is bright and the wind cool

master of none

cock-a-hoop(elated; exulting; jubilant; be heaved with joy; be on the hight rope)

be of one heart and one mind
