well before and long after怎么翻译

Curb Bad Habits. Well before and long after your surgery, you will be expected to cut the cigarettes and cigars if you are a smoker.

控制（你的）坏习惯：外科手术之前及之后很长一段时间，如果你是一个吸烟者，希望你能戒掉香烟和雪茄。

Well before （某事）之前很长一段时间
long after 之后很长一段时间

soon after 不单独使用。后面要有介词从句。意思是：在，，之后不久，或马上。可根据介词后从句时态来选择主句时态。如 soon after you arrive there ,you will call me . after a while是一介词短语可以单独使用做句子的时间状语。用过去时。如 he entered the room and after a while a strange sound came from the room. before long 也是一固定短语，单独用做时间状语，意思是：不久，用于过去时和将来时。如 he graduated from a university last month and before he found a job. he has just returned from beijing and before long he will go to shanghai.
