to give someone a good talking/scolding – to scold someone thoroughly, usually a child as a punishment
e.g. Tom’s mum gave him a good scolding for pulling up the neighbour’s flowers.
for good – permanently
e.g. Tim lived in Australia for 1 year but he has come back home for good.
keep out of something – not get involved in
join in – participate in, e.g., Why don’t you join in? We’re having fun.
to go ahead – to begin
keep someone in – punish by detaining after school.
how come? (informal) – why? how does/did it happen that…?
how’s that? – why? what is the reason for that?
A FLAT TYRE – A TYRE WITH NO OR NOT ENOUGH AIR IN IT
TO HAVE A GOOD TIME – TO ENJOY ONESELF
