just as的用法

问题描述

Though it may be difficult to imagine from a later perspective, a strain of critical opinion in the 1920s predicted that sound film would be a technical novelty that would soon fade from sight, just as had many previous attempts, dating well back before the First World War, to link images with recorded sound.

“just as had many previous attempts”是什么成分？比较状语从句吗？这句话had的主语是什么？

【翻译】虽然按后来的观点看，这也许是难以想象的，但在20世纪20年代，一种批评性的观点就预言，有声电影是技术上的新生事物，很快就会淡出视线，正如追溯至一战前，将画面与录音连接在一起的多次尝试一样。

【分析】just as had many previous attempts，是as引导的方式状语从句。

1. 这还是一个倒装句。正常语序是：just as many previous attempts had (faded)，为避免重复只保留助动词had。倒装的原因是因为主语太长（含有较长的定语）。

2. to link images with recorded sound，动词不定式作定语，修饰attempts。

3. dating well back before the First World War，现在分词短语作时间状语。
