托福听力听不懂不要慌 掌握4步听力法快速提升

托福听力提升方法第一步 概听

初听就是将一段材料先做了解。首先我们要将材料听1-3遍，具体次数可以由材料难度来判断。这几遍听力里面重点听出文章的大意。

尤其是在“初听”的后几遍新托福听力中，可以将自己听材料的重心放在前面没有听出的题目或者内容上面，甚至可以总结出自己在听第一遍中有什么地方听的不是特别流畅，什么听力习惯不是很好，以便在以后的听力中不犯同样的错误。

托福听力提升方法第二步 细听

这步在整个托福听力备考中非常重要。在这次的听力以前，需要将文字答案仔细研究。由于我们前面已经听过数遍了，有的地方如果不参考文字答案是肯定无法听出来的，这样在通过对于文字答案详细的阅读以后，能够明确听力材料的内容，同时找到一些教难的词汇以及一些常考词汇，如果是使用剑桥还可以对照题目找出其中的同义词汇。

如剑7 Test 4 Section 2最后一题的文字答案为：And finally let‘s pass by the Waterbird Refuge.This area is in a sheltered part of estuary， that’s why the park‘s viewing shelter is a favourite spot for bird watchers who can use it to spy through binoculars.这边出现了几个比较生僻的词语：estuary河口，binoculars双筒望远镜，而此题的答案viewing shelter 也是一个比较难的词语，因此在这个地方如果不看文字答案将很难听明白。

再比如剑7 Test 3 Section 2第17题，文字答案为：you’ll start the trek on Day Three walking through the enormous Katiba Forest which will take the whole of the day.此题要听出答案forest并不是很难，但是前面的专有名词确实不可能能听出来的，通过文字答案也能更加好的了解具体内容。

在弄明白了文字答案以后，小编建议考生再次听一遍文章，这次听力非常重要，一定要力求听懂里面的内容。如果还是遇到了没有听清楚的部分，将听力材料停下来，看一遍听不出来的内容，然后将这个部分再听一遍。这步的要点就是“看听分开”。最终达到能够毫无难度的听完整个内容。由于事先已经将文字材料研究透彻，因此这次听力可以很快就达到目标。

托福听力提升方法第三步 冷却

当我们将一段材料听过这么多遍之后，这个听力法的精髓就是冷凝。需要将现在已经听的很熟的材料放到一边，冷却下来。对于同一个材料听的次数过多最终导致的结果就是对于材料的麻木而无法再继续听下去了，这样反而无法达到很好的听力的效果，而且如果由此产生了对细听的厌恶，反而是得不偿失。其实冷凝并不仅仅是冷却，而是要将刚刚学的内容让其下意识的在大脑里进行回顾。

托福听力提升方法第四步 回暖

经过1至2个星期的冷却，我们可以将前面进行细听的材料再次拿出来听一遍，由于经过前面的训练，这次熟练度一定非常不错，对于英语的信心度可以提升不少，再次回顾这个材料，也可以加深对前面不熟悉内容以及词汇的印象。经过这样一个循环，许多内容就可以更加纯熟了。然后可以再次冷却，再经过一段时间再次回暖。几次循环以后，很多内容自然而然的就能印入大脑了。

运用科学的方法才能学出自己想要的效果，上文中为大家介绍的托福听力提升方法希望大家能够积累学习，听力提升需要多练，更需要在正确的方法指导下练习。

2020托福听力练习：分子机器研究获诺贝尔奖

Got a minute?

"This year's Nobel Prize in Chemistry is about the world's smallest machines."

Göran Hansson, secretary general of the Royal Swedish Academy of Sciences, earlier this morning.

"The Royal Swedish Academy of Sciences has decided to award the 2016 Nobel Prize in Chemistry jointly to Jean-Pierre Sauvage, Sir James Fraser Stoddart and Bernard L. Feringa for the design and synthesis of molecular machines."

Sauvage was born in Paris and is now an emeritus professor at the University of Strasbourg. Stoddart comes from Edinborough and is now at Northwestern University in Illinois. Feringa is from the Netherlands and is at the University of Groningen.

Following the announcement, Feringa called in and explained some of the potential applications for the microscopic machines.

"First of all let me say I feel a little bit like the Wright Brothers, who were flying a hundred years ago for the first time. And then people were saying, 'You know, why do we need a flying machine?' And now we have a Boeing 747 and an Airbus. So that is a bit how I feel...but once you are able to control movement, you have a motor, you can think of all kinds of functions."

"So indeed, we think of transporters, like in your body there are many motors and machines that make it possible that your cells divide, that your muscles work, that there is transport in the cells, etc. But you can think also much broader. Think about nanomachines, microrobots, think about tiny robots that the doctor in the future will inject in your bloodstreams and that go to search for a cancer cell or are going to deliver a drug for instance. But also smart materials, for instance, materials that can adapt, change, depending on an external signal, just like our body functions. That is the kind of functions you can think of."

2020托福听力练习：食品乳化剂引发肥胖

Inside our guts is a diverse ecosystem of bacteria:the microbiome.

But the makeup of the community can depend on what we eat.

Emulsifiers are food additives that extend the shelf life of processed foods.

And now research with mice finds that consuming emulsifiers may throw off the microbiome's delicate balance and thereby contribute to obesity and inflammatory bowel disease.

In the study, mice were fed doses of common emulsifiers in their water and mouse chow.

The substances appeared to make it easier for gut bacteria to chew through the layers of mucus that typically line the intestine.

The result was the triggering of chronic colitis in mice with impaired immune systems that predispose them to the condition.

And even in mice with normal immune systems, emulsifier consumption appeared to trigger mild intestinal inflammation.

These mice then tended to overeat and become obese and insulin resistant.

The study is in the journal Nature.

Could emulsifiers cause the same health consequences in humans and be behind some of the obesity trend?

The researchers hope to find out in future studies.

If nothing else, they write that their new finding suggests that there should be improved testing on the total health effects of chemicals in our food.
