полная чашка молока, толкнуть дверь, извилистая тропка, заводить часы, чистая скатерть, с сожалением, твердое решение, подоткнуть одеяло, близкий друг, воза с фруктами, с трудом сводить концы с концами, стучать в окно, говорить с сожалением, полная столовая ложка лекарства, легкая коробка, свеча в подсвечнике, борьба с врагами, скакать как мячик по комнате.

A full cup of milk, to push the door, a winding path, to wind the watch,  a clean tablecloth,   pityingly, a tough decision, to tuck a blanket, a close friend, a vase with fruit, to make both ends meet, to knock on/at the window,  to speak pityingly (with regret), a full tablespoon of medicine, a light box, a candle in the candlestick, a fight with enemies, to jump/bounce in the room like a ball.
