Answer 1

C
“It is + 一段時(shí)間 + since + 從句”意思是“自....發(fā)生以來(lái)已經(jīng)一段時(shí)間了”。如：it is three years since he died.(自)他去世以來(lái)已經(jīng)三年了�！癐t is + 一段時(shí)間 + before + 從句”意思是“過(guò)了一段時(shí)間...才發(fā)生”。如：It is 3 years before they accept the fact.過(guò)了三年他們才接受這個(gè)事實(shí)。故根據(jù)句意選C：這是幾年以來(lái)我才玩得如此開(kāi)心。
