听力提高是需要不断的练习来进行的，和背单词一样，人是不可能一下子就学会的。要合理地利用时间和资源，并且持之以恒地去做。自己能完成的大致有三个环节，精听，泛听和学科词汇，除此之外就是每个题型的针对练习需要授课老师的分析讲解，再结合模考来检验学习成果和进度。
2、ETS经常会采用的对比，转折 。呈现两者做对比的，前后逻辑有转折关系的，都是潜在的考点。下面的信号词：做对比的，compared to, by contrast, on contrary, contradictory, on the other hand;表转折的：however, but 这点也是基本上每一篇都会出题的中央，这些信号词后面跟着的内容，就是标题的答案。
【举个例子】
TPO5 L4中: On the other hand, descriptions of characters and settings can be developed more completely.
TPO17 L4中: The octopus can release a cloud of ink if it feels threatened. But it doesn’t hide behind it, as is generally believed. Um, the ink cloud is ... it serves to distract a predator while the octopus makes its escape.
TPO 5 L1中: An organism often cannot survive with a mutated gene. And so a gene usually cannot be passed on, unless it’s an exact copy. For memes however, fidelity is not always so important.
3、承认 在对话或者讲座中，说话者表达承认的：have no…, without，can’t be ;以及讲座中提及某个学术知识时，呈现的否性形容词，比如：unusual, irrelevant，impossible。
【举个例子】
TPO9 L3: First the rains that fell there were torrential. So it would've been impossible for all the water to soak into the ground.
TPO1 L3: And it maybe this burial custom that explains why the houses were packed in so tightly without streets.
4、表达观念和态度
对话中一般呈现，说话者的态度;讲座中会呈现教授关于某个理论的观念，或者陈说某一个，几个科学家的观念。以下是考点信号词：think, feel, believe, criticize, guess, assume/assumption, speculate/speculation, evidence, convincing 观念的表达分为三类，肯定，承认，不肯定。
【举个例子】
TPO11 L1：And in a broken wing display the bird spreads and drags the wings or its tail, and while it does that, it slowly moves away from the nests so it really looks like a bird with a broken wing. And these broken wing displays can be pretty convincing. 教授以为这些broken wing display压服理十分强，表示肯定的态度。
