问题 Some selected recruits have been trained at the overseas branches ________the past three months.
选项 A、over
B、since
C、forward
D、meantime
答案 A
解析 have been trained是现在完成时。经常和现在完成时一起搭配的是since和for. for后加一段时间，since后加一个时间点。句子中说的是“过去这3个月”，因此不用since而应该用for。能代替for的是in和over。那么这里就选择over。forward是表示地点的介词；meantime(其间)是副词。空格内应填入的是介词over。
