托福聽力考試確實(shí)是很難，如果不掌握正確的練習(xí)方法提升起來會(huì)更加苦難。下面小編就和大家分享托福聽力掌握4步聽力法快速提升，歡迎閱讀!

托福聽力聽不懂不要慌 掌握4步聽力法快速提升

托福聽力提升方法第一步 概聽

初聽就是將一段材料先做了解。首先我們要將材料聽1-3遍，具體次數(shù)可以由材料難度來判斷。這幾遍聽力里面重點(diǎn)聽出文章的大意。

尤其是在“初聽”的后幾遍新托福聽力中，可以將自己聽材料的重心放在前面沒有聽出的題目或者內(nèi)容上面，甚至可以總結(jié)出自己在聽第一遍中有什么地方聽的不是特別流暢，什么聽力習(xí)慣不是很好，以便在以后的聽力中不犯同樣的錯(cuò)誤。

托福聽力提升方法第二步 細(xì)聽

這步在整個(gè)托福聽力備考中非常重要。在這次的聽力以前，需要將文字答案仔細(xì)研究。由于我們前面已經(jīng)聽過數(shù)遍了，有的地方如果不參考文字答案是肯定無法聽出來的，這樣在通過對(duì)于文字答案詳細(xì)的閱讀以后，能夠明確聽力材料的內(nèi)容，同時(shí)找到一些教難的詞匯以及一些?？荚~匯，如果是使用劍橋還可以對(duì)照題目找出其中的同義詞匯。

如劍7 Test 4 Section 2最后一題的文字答案為：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.這邊出現(xiàn)了幾個(gè)比較生僻的詞語：estuary河口，binoculars雙筒望遠(yuǎn)鏡，而此題的答案viewing shelter 也是一個(gè)比較難的詞語，因此在這個(gè)地方如果不看文字答案將很難聽明白。

再比如劍7 Test 3 Section 2第17題，文字答案為：you’ll start the trek on Day Three walking through the enormous Katiba Forest which will take the whole of the day.此題要聽出答案forest并不是很難，但是前面的專有名詞確實(shí)不可能能聽出來的，通過文字答案也能更加好的了解具體內(nèi)容。

在弄明白了文字答案以后，小編建議考生再次聽一遍文章，這次聽力非常重要，一定要力求聽懂里面的內(nèi)容。如果還是遇到了沒有聽清楚的部分，將聽力材料停下來，看一遍聽不出來的內(nèi)容，然后將這個(gè)部分再聽一遍。這步的要點(diǎn)就是“看聽分開”。最終達(dá)到能夠毫無難度的聽完整個(gè)內(nèi)容。由于事先已經(jīng)將文字材料研究透徹，因此這次聽力可以很快就達(dá)到目標(biāo)。

托福聽力提升方法第三步 冷卻

當(dāng)我們將一段材料聽過這么多遍之后，這個(gè)聽力法的精髓就是冷凝。需要將現(xiàn)在已經(jīng)聽的很熟的材料放到一邊，冷卻下來。對(duì)于同一個(gè)材料聽的次數(shù)過多最終導(dǎo)致的結(jié)果就是對(duì)于材料的麻木而無法再繼續(xù)聽下去了，這樣反而無法達(dá)到很好的聽力的效果，而且如果由此產(chǎn)生了對(duì)細(xì)聽的厭惡，反而是得不償失。其實(shí)冷凝并不僅僅是冷卻，而是要將剛剛學(xué)的內(nèi)容讓其下意識(shí)的在大腦里進(jìn)行回顧。

托福聽力提升方法第四步 回暖

經(jīng)過1至2個(gè)星期的冷卻，我們可以將前面進(jìn)行細(xì)聽的材料再次拿出來聽一遍，由于經(jīng)過前面的訓(xùn)練，這次熟練度一定非常不錯(cuò)，對(duì)于英語的信心度可以提升不少，再次回顧這個(gè)材料，也可以加深對(duì)前面不熟悉內(nèi)容以及詞匯的印象。經(jīng)過這樣一個(gè)循環(huán)，許多內(nèi)容就可以更加純熟了。然后可以再次冷卻，再經(jīng)過一段時(shí)間再次回暖。幾次循環(huán)以后，很多內(nèi)容自然而然的就能印入大腦了。

運(yùn)用科學(xué)的方法才能學(xué)出自己想要的效果，上文中為大家介紹的托福聽力提升方法希望大家能夠積累學(xué)習(xí)，聽力提升需要多練，更需要在正確的方法指導(dǎo)下練習(xí)。

2020托福聽力練習(xí)：分子機(jī)器研究獲諾貝爾獎(jiǎng)

Got a minute?

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

G?ran 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托福聽力練習(xí)：食品乳化劑引發(fā)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.
