--- It’s a long time ______ I saw you last.
-----Yes, and what a pity it is now that it will be a long time _____ we see each other again.
A．since; whenB．before; sinceC．when; beforeD．since; before
D
考查固定句型。第一空根據(jù)時態(tài)及句意可知應(yīng)該用since.第二空的句型：it be 一段試卷before從句；意為：一段時間以后某事才發(fā)生。句意：—自從上次看見你到現(xiàn)在有很長時間了!—是的，如此長時間以后我們才能再一次見面真是一件遺憾的事情。
