as far as1：像xxx一样远2:as so asas well asas long as这是一个as,as 比较句式.比较的成分是表数盯语部薯坦和分,as convincing an answer to the efforts undertaken in Tehran over the last few days 和any we could provideto the efforts undertaken 是不定式做answer定语,in Tehran 地点状语,over the last few days 时间状语.as any we could provide其中any announcement 的缩写,we could provide是定语从句修饰any announcement ,,as,as 中第一个AS 是副词信运通常修饰形容词如 convincing ,而第二个AS是连词,连接句子,或者是句子的省略成分.这样的句子很多,看看语法书中的形容词,副词比较级,就可以了
