　　托福长难句类型：层层追加的复杂修饰+插入成分

　　本句也是ETS的老套路了，为了把句子变长，就层层追加修饰成分，先又Though it may be difficult to imagine from a later perspective所谓一个转折的分句，然后主句是a strain of critical opinion in the 1920 s predicted that sound film would be a technical novelty ，接着用that引导 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的长句嵌套插入成分，来修饰novelty,但是实际上这些都不是什么重要的成分，大家只要读出来主句结构和句子的核心意思就是以前有一种预言认为有声电影很快就会消失就行了。

　　译文：

　　尽管后来人很难理解，但在20世纪20年代，一种批判性的意见预言：有声电影是一种将很快淡出公众视线的科技新事物，就像的许多先前把图像和声音结合起来的尝试，这些尝试可以追溯到第一次世界大战。

　　意群训练：
