Question

Good to see you again. It’s almost three years _______ we met last time.

A．until

B．before

C．while

D．since

Answer 1

D

詞義辨析。until 直到；before 在……之前；while當(dāng)……時(shí)候；since
自從。句意：再次見到你太好了。自從我們上次見面已經(jīng)三年了。Since加過去時(shí)間，謂語動(dòng)詞通常用現(xiàn)在完成時(shí)態(tài)或一般現(xiàn)在時(shí)態(tài)。所以選D。
