托福听力讲座是听力中最难的部分，篇幅太长，内容丰富，学术性强。想要听懂托福听力讲座，可不只需要理解力，还要把握技巧。比如要想弄清托福听力讲座结构，要把握什么技巧呢?跟随环球偶遇小编一起来看。

　　一.找到结构词

　　托福听力讲座中教授会给学生一个完整的思路。尤其是大学学术性内容，结构一般是清晰的。而且，教授的话语中会有一些结构词，这些词可以将内容分层，只要把握这些词就能把握内容结构。以托福TPO5中的第一个讲座部分内容为例：

　　First, longevity.//A replicator must exist long enough to be able to get copied, and transfer its information.Clearly, the longer a replicator survives, the better its chances of getting its message copied and passed on.So longevity is a key characteristic of a replicator.//If you take the alligator story, it can exist for a long time in individual memory, let's say, my memory.I can tell you the story now or ten years from now, the same with the twinkle, twinkle song.So these memes have longevity because they are memorable for one reason or another.

　　托福听力讲座结构分析：内容中出现First但是没有Second等的出现，说明这部分重心在于“longevity”。First是一个结构词。顺便更细致分析一下内容：看出这部分内容可以分为三部分，为大家在内容中标识。第一部分是主旨句;第二部分理论说明“longevity is a key characteristic of a replicator”;第三部分则是具体的例子。

　　二.找到更具体的关系词

　　在托福听力讲座中到处有表达各种连接关系的词语，我们同样可以加以利用，比如几种常见的逻辑关系，并列关系，转折关系，因果关系以及对比关系等。这些逻辑关系可以帮助我们把握细节之间的关联，把听到的细节的信息串联起来整体理解。比如TPO10中的第一个讲座内容(Whales)中的部分内容：

　　The name Ambulocetus natans comes from Latin of course, and means "walking whale that swims".It clearly had four limbs that could have been used for walking.//It also had a long thin tail, typical of mammals, something we don't see in today's whales.//But it also had a long skeletal structure, and that long skeletal structure suggests that it was aquatic.

　　托福听力讲座结构分析：先找出能体现关系的词“and ”、“also”、“But”。可以分析出这部分内容可以分成三个部分，三个部分通过并列逻辑相联系。可以看托福听力真题来更深刻理解内容。例：

　　According to the professor, what three aspects of the Ambulocetus fossil make Ambulocetus a likely bridge between land mammals and sea mammals?Click on 3 answers

　　A. It had an elongated skeletal structure

　　B.It strongly resembled a modern hippopotamus

　　C.It had an unusually kind and thin tail for a whale

　　D.It had limbs that could have been used for walking

　　E.Its skull had ear bones characteristic of land mammals

　　真题分析：在介绍Ambulocetus natans的具体特点时，连续用了三个并列句，and,also等表并列的过渡词来串联。那么段落当中的limbs,tail和skeletal structure作为三个连续的特点应在此选出。
