back and forth
to go between two places, again and again
(رفتن و آمدن مکرر بین دو مکان)
He bikes back and forth between his job and his apartment every day.
او هر روز با دوچرخه بین محل کار و آپارتمانش رفت و امد می کند
We travel back and forth all the time between Canada and England.
او دائما بین کانادا و انگلستان سفر می کند
We had to go back and forth many times before we moved all our furniture to the new house.
ما مجبور بودیم قبل از انتقال اسباب و وسایل به خانه جدید، بارها بریم و بیائیم
