【归纳拓展】

本句型中，before引导一个时间状语从句。before的本意为“在……之前”，但如果主句是肯定句，并且与时间段连用，意为“……之后才……”，表示主句的动作发生得迟缓。

It will not be long before... 不久就会……从句常用一般现在时

It will be＋时间段＋before... 要过多久才【语境助记】

8 从句常用一般现在时

任何事情！

【归纳拓展】

so/such...that...意为“如此……以至于……”，引导结果状语从句。

(1)so...that...句型的常见形式：

so＋adj./adv.＋that...so＋adj.＋a/an＋单数可数名词＋that...少＋n.＋that...so＋many/few/much/l(2)such...that...句型的基本结构：

such＋a/an＋adj.＋单数可数名词＋that...such＋adj.＋复数可数名词/不可数名词＋that...

(3)当so/such及其后成分放在句首时，主句用部分倒装。
