遇到这种句子时，往往需要我们更加细心，把句子的主干先抓出来，然后结合这些修饰成分有层次的理解句子。而抓住句子的核心主干的窍门往往在于找出句子的真正谓语，因为谓语是支撑整个句子的支点。

　　名师详解托福阅读中的复杂修饰成分句子1：

　　1.In many instances， spectators in the era before recorded sound experienced elaborate aural presentations alongside movies' visual images， from the Japanese benshi (narrators) crafting multivoiced dialogue narratives to original musical compositions performed by symphony-size orchestras in Europe and the United States.

　　托福阅读中的难句类型：复杂修饰成分

　　本句主干结构是spectators experienced elaborate aural presentations alongside movies' visual images，其实非常简单，就是说观众们既看到影像也欣赏到了音效。但是从句子一开头的状语In many instances开始，作者用in the era before recorded sound 修饰主语spectators，割裂了谓语 experienced和主语之间的关系，然后宾语是 elaborate aural presentations alongside movies' visual images倒不难，但是随后用一个 from the Japanese benshi (narrators) crafting multivoiced dialogue narratives to original musical compositions performed by symphony-size orchestras in Europe and the United States.来解释这个主干成分的句子。就使句子变得很复杂了。

　　托福阅读中的难句类型：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。

　　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。
