insider; person in the know

day before yesterday

what time; when

inside information/story

tie a knot

do some shopping

have a general idea (of)

send 200 students abroad

get a good bargain

save three match points

beat sb unconscious

have some meal

an unexpected opponent or disruptor appears halfway

be busy all day long

fall flat on one's back

push him over

poem of 5 verses

give birth to a daughter

eat up all the dishes

you can't build up your constitution on one mouthful; Rome was not built in a day
