句型公式：“be to do”结构的用法
【教材原句】　Its ashy rocks, now dark, now light, told a story of past eruptions that might have warned the city what was to come!
火山岩忽明忽暗，讲述着过去火山几度喷发的故事，这本来可以警告这座城市里的人们，灾难即将降临！
【记牢】　
“be to do”结构表示将来，主要有以下三方面的含义：
(1)表示注定要发生的或不可避免会发生的事情；
(2)表示按照计划、安排即将发生某事或者打算做某事；
(3)表示意志、意图、职责、义务、命令等。
点津：“be to do”结构中，若do与句子的主语构成逻辑上的动宾关系，动词不定式要用to be done的形式。
句型公式：状语从句的省略
【教材原句】　Its walls were fresh as if painted yesterday ...
【记牢】　
(1)as if引导方式状语从句。在此句中，as if 后省略了they were。
(2)当时间、条件、让步、方式等状语从句的主语与主句主语一致(或者从句主语是it)，且从句谓语含有be动词时，为了简练，可以将从句的主语和be动词一起省略。
