　把语句的骨干先抓出来，然后联系这些润饰成分有层次的理解语句。而捉住语句的中心骨干的诀窍通常在于找出语句的真实谓语，由于谓语是支持全部语句的支点。

　　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.

　　托福阅览难句类型：杂乱润饰成分

　　本句骨干构造是spectators experienced elaborate aural presentations alongside movies' visual images，本来十分简略，即是说观众们既看到印象也赏识到了音效。可是从语句一最初的状语In many instances开始，作者用in the era before recorded sound 润饰主语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，可是随后用一个 from the Japanese benshi (narrators) crafting multivoiced dialogue narratives to original musical compositions performed by symphony-size orchestras in Europe and the United States.来解释这个骨干成分的语句。就使语句变得很杂乱了。

　　译文：

　　很多时分，在有声年代之前，观众们在观看印象的一起也赏识到了精心制作的音效，从日本多人对话式叙事到欧美交响乐团的原声乐，无不表现这一点。

　　练习：

　　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.

　　2.Though it may be difficult to imagine from a later perspective, a strain of critical opinion in the 1920 s 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.

　　托福阅览难句类型：层层追加的杂乱润饰+刺进成分

　　本句也是ETS的老套路了，为了把语句变长，就层层追加润饰成分，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的长句嵌套刺进成分，来润饰novelty,可是实际上这些都不是什么主要的成分，大家只需读出来主句构造和语句的中心意思即是曾经有一种预言以为有声电影很快就会不见就行了。

　　译文：

　　尽管后来人很难理解，但在20世纪20年代，一种批判性的定见预言：有声电影是一种将很快淡出大众视野的科技新事物，就像的很多从前把图画和声响联系起来的测验，这些测验可以追溯到第一次世界大战。

　　练习：

　　Though it may be difficult to imagine from a later perspective, a strain of critical opinion in the 1920 s 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.

　　3.Indeed, stability of the biological clock's period is one of its major features, even when the organism's environment is subjected to considerable changes in factors, such as temperature, that would be expected to affect biological activity strongly.

　　托福阅览难句类型：杂乱润饰+刺进成分

　　本句的主句构造本来格外简略即是 stability is one of its major features, even when 引导的状语从句the organism's environment is subjected to considerable changes in factors,然后用 such as引导了列举temperature,之后再用 that引导从句来阐明temperature would be expected to affect biological activity strongly.

　　译文：

　　事实上，即便有机体受到外界因素，如温度，激烈改动的影响，有机体内生物钟的稳定性是影响生物活动的一个主要因素。

　　练习：

　　Indeed, stability of the biological clock's period is one of its major features, even when the organism's environment is subjected to considerable changes in factors, such as temperature, that would be expected to affect biological activity strongly.
