托福考试中出现长难句的部分多为阅读，因此考生对于长难句的训练也往往集中在看懂上。其实除了阅读以外，托福听力中也会不时出现一些结构略为复杂的句式，大家也需要具备听懂它们的能力。下面就让小编结合实例分析听懂托福听力复杂句式的重点要点。Isn’t that just for when you need help with writing/, like an essay or research paper? (TPO24-C2)同学们一听就会知道是个问句，以及会听到writing、research paper这些词，但会感觉开头有点快，这一点主要因为发音快导致不易辨认清楚。本句其实是Isn’t just for sth.这种反问句句式，在听的方面主要是区分isn’t that和is that的发音;在理解上就要注意反问句所表达的偏强调的意思。But actually, it was a physicist/ who came up with a method that was a breakthrough. (TPO15-L3)这句话较简单，主要是同学们容易听懂了仍然不清楚这是强调句型it was sb. who…，而这个句型基本上是初中语法知识，但你看，作为用得少的典范，就容易反应不出，即使它再简单。
So the original hypothesis/ that the stones found with sauropods were gastroliths/, even though it hasn’t been supported/, has helped us to make new hypothesis/, which may eventually lead to the answer. (TPO27-L3)这句话比刚才的难度要大，首先要判断出that引出同位语，指hypothesis，所以从the original hypothesis到gastroliths是主语，根据我们上一期文章提到的抓“核心主谓宾”的方法，要有意识抓谓语动词。接着听到even though，这个时候就要召唤语法预判能力了，因为even though固定搭配“虽然…但是…/即使…也…”，所以even though引导的都是让步从句，我们仍然要抓主句，也就继续等待刚才“the original hypothesis…gastroliths”主语部分之后的谓语动词出现，此后我们听到has helped…确定谓语动词。到此为止，主干部分已经清楚So the original hypothesis…has helped us to make new hypothesis。最后which引导定语从句修饰new hypothesis，较简单。另外本句要注意听出hasn’t been supported, has helped的否定和肯定，否则逻辑仍会混乱。本句语法成分较多：同位语，插入语，定语从句，但相对最难的是插入语。It was presented in the works of well-known Greek philosophers/ as early as the fourth century B.C.E. (TPO21-L1)本句如果遍没听懂，则要在精听中的第二遍听主干，也就是核心主谓宾：It was presented…再在第三遍抓里面的细节，也就是其他介词引导的部分;其中注意连读works of，as early as;本句为大家也用得相对较少的被动句句式。Only after the site at Gonur-depe was excavated/ were archaeologists able to identify it/ as coming from Gonur-depe. (TPO28-L4)本句首先听听前半部分有明显的停顿were，那么迅速判断only after…were是明显的倒装句。事实上本句很多同学看都不一定看得懂，这就考查语法功底的扎实程度了。以上就是托福听力中听懂复杂句式长难句的一些实例分析，希望大家能够从中收获到一些技巧要点，顺利听懂这些高难度的句式。
