before引导的时间状语从句是什么?
before引导的时间状语从句：
before意为“在……之前；还未……就……；……之后才……”引导时间状语从句时，主句为肯定句时，before引导的从句动作后发生；主句为否定句时，before引导的从句动作先发生。例如：

Before I could say a word, he ran away.我还没来得及说话，他就走了。
He didn't arrive before I returned.在我回来之前他尚未到达。
注意：before意为“在……之前”，其引导的时间状语从句遵循“主将从现”原则，即主句是一般将来时，从句用一般现在时替代一般将来时。since意为“自从……以来”，since引导时间状语从句使用一般过去时，主句使用现在完成时（since的特殊句型“It is +一www.souquanme.com段时间＋since从句”除外，该特殊句型主句用一般现在时，从句用一般过去时。）。例如：

2.、 It+be+not long before ……
