Good to see you again.It's almost three years ___ we met last time.
A.until B.before C.while D.since 我选了B,可是答案选D,可是我觉的since用于现在完成时,since加过去时间点,可是我还是觉得选B,意思是很高兴再一次见到你,这是我上一次见到你之前几乎三年了.

答
你好,
为你解答,
对于since的理解,你是正确的,它是多用于现在完成.但是它后面也可以跟句子,不一定就要跟时间点.
本题 It's almost three years since we met last time = It's been almost three years since we met las t time.
又如：It has been two years since he became a football player = He has been a football player since two years ago.
基本句型It is +一段时间＋since+一般过去时或现在完成时.
例如: It's twenty years since I've known her.我认识她已经二十年了.
How long is it since we last went to the theatre? 我们多久没去看戏了?
上面的知识点记住就行了.
