It’s ten years _____ we met each other last time.A.before B.since C.after D.when
选B
上次我们见面到现在已经十年了.
首先 before （在...以前）不行,when（当...时）不行.
after引导的词组所表示的时间是纯系过去,并不延续到说话时,因此要和一般过去时连用.
例如：He went home after school.
after 也不行
since引导的词组所表示的时间一直延续到说话时为止,因而要与现在完成时连用.
例如：He has been there twice since 1982.I have done nothing since six o”clock.
选 since
