托福聽力中考生經(jīng)常遇到的問題之一是聽不懂。而為了應(yīng)對這個問題，考生可能會從很多角度來尋找解決方法。其實(shí)聽不懂的情況也需要分成很多種，不同的情況需要各自針對性的改善方法。下面小編就和大家分享托福聽力聽不懂3類主要原因分析，歡迎閱讀!

托福聽力聽不懂3大類原因分析

都說托福聽力聽不懂只要多練就行了，但這種說法未免太過簡單粗暴，而導(dǎo)致考生聽不懂聽力素材在說什么的原因其實(shí)有很多，發(fā)生在大部分考生身上的聽不懂原因主要可以分為以下三種：

1. 沒聽清聽力素材的發(fā)音

這種聽不懂的情況是最基礎(chǔ)的問題，也就是考生在聽音辨音的能力上存在一定問題，聽不清楚或是無法準(zhǔn)確分辨出一個單詞的具體發(fā)音。導(dǎo)致這種情況的原因主要是因?yàn)榭忌约旱陌l(fā)音就不太標(biāo)準(zhǔn)，缺乏足夠的發(fā)聲練習(xí)，也沒有做過發(fā)音校正，自己對詞匯發(fā)音的記憶就有錯誤，聽到正確發(fā)音反而聽不出來也就在所難免了。

2. 聽不懂說的是什么詞匯

第二種聽不懂的情況是考生雖然能夠聽清發(fā)音，但卻辨識不出來說的是哪個詞匯。有些同學(xué)對詞匯的記憶存在一定的盲區(qū)。在背托福詞匯的時候過多的把注意力放在了詞匯的拼寫含義和書面使用等方面，而忽略了詞匯的發(fā)音，只是記住了一個大概，這就會造成大家能夠看懂詞匯甚至熟練使用，在聽力中卻分辨不出來到底是哪個詞匯的問題，這種不清楚詞匯發(fā)音的情況也就是俗稱的啞巴英語，在中國考生當(dāng)中較為普遍，也是導(dǎo)致許多同學(xué)聽不懂托福聽力在講什么的主要原因之一。

3. 能聽出詞匯但連起來就聽不懂了

最后一種情況則是考生能夠聽懂詞匯，但對于較長的句子則聽不太懂意思。這種情況從句子的層面來看，說明考生缺乏對英語句式的掌握和理解，或者在面對完整句子的聽力時反應(yīng)不過來，能聽清每個單詞，但是連在一起就不知道是什么意思了。

當(dāng)然，小編認(rèn)為托福聽力會聽不懂，很多時候并不是因?yàn)樯鲜?個原因中的1個單獨(dú)作祟，而是2個甚至3個原因同時存在才造成了困擾。所以，考生要做的就是結(jié)合自身的情況，對導(dǎo)致自己托福聽力聽不懂的原因做詳細(xì)分析理解，并采取具有更強(qiáng)針對性的方式來進(jìn)行訓(xùn)練以從根本上解決問題。

托福聽力聽不懂問題如何解決?

其實(shí)想要解決托福聽力聽不懂的問題，考生只需要做好聽抄練習(xí)就能基本達(dá)成目標(biāo)。所謂聽抄練習(xí)，就是通過邊放音頻邊做聽寫的方式來進(jìn)行訓(xùn)練。這種練習(xí)的目的在于提升考生對聽力素材的精確理解能力，幫助大家更準(zhǔn)確地聽懂素材里的每一句話。想要達(dá)到這個目的，考生做聽抄練習(xí)就不能只是簡單的聽寫記錄，需要按照嚴(yán)格的練習(xí)步驟來進(jìn)行訓(xùn)練。具體步驟是：

1. 首先，考生需要先完整聽一遍素材的全文從而了解文章的大意;

2. 然后再一次聽全文，這次需要對文章里涉及到主旨觀點(diǎn)的具體信息和話題的相關(guān)關(guān)鍵詞進(jìn)行記錄;

3. 第三個步驟才是逐個句字的聽寫練習(xí)。大家可以結(jié)合自己的實(shí)際水平在記錄過程中采用聽幾句暫停一下的方式，但需要按照先記下句子主干再返回重聽補(bǔ)充細(xì)節(jié)的做法來還原整個句子，記住一定要以完整句子為基本練習(xí)單位進(jìn)行聽寫;

4. 最后一步是在聽寫完所有內(nèi)容后再參照原文做對比總結(jié)，從中發(fā)現(xiàn)自己的問題，特別是詞匯方面沒聽出來或者語法上存在缺陷的地方，及時補(bǔ)強(qiáng)。

通過這個完整的步驟來進(jìn)行聽抄練習(xí)，上文提到的這些問題就都能比較好的解決了。

2020托福聽力練習(xí)：資源回收是否真的有效

At Brooklyn's recycling depot, discarded metal and plastic gets bulldozed into a large mound.

The stuff is then scooped onto the first of a series of rising conveyor belts, from which the trash is sorted through means both mechanical and manual.

All that effort produces a variety of salable products, from metals to paper fibers.

But is it worth it?

In the case of an aluminum can the answer is an unqualified yes.

Such a can can be recycled endlessly with no loss of quality.

And recycling a can uses less than five percent of the energy that it takes to refine bauxite ore into fresh aluminum.

Recycling is worth it when it comes to all metals, though we're better at recycling aluminum than say neodymium.

In principle it could work for plastic, too.

But because plastic is made from petrochemicals, low oil prices can make it cheaper to just dump old plastic and manufacture new.

And plastics degrade as they're recycled, as does paper.

That said, a simple cost-benefit analysis does not correctly measure the environmental costs of dumping plastics or cutting down more trees for paper products.

The EPA suggests that recycling in the U.S.reduces the same amount of greenhouse gas pollution as taking more than 38 million cars off the road.

The sound of recycling may prove music to the ears of future generations.

2020托福聽力練習(xí)：新型智能鍵盤可識別主人

Keyboards don't exactly spring to mind when you think of high-tech innovations, especially now that we have voice and even gesture controls for our gadgets.

Still, a new device out of the Georgia Institute of Technology is taking typing in a smart direction.

The Georgia Tech researchers have developed an intelligent keyboard that captures information about the force and length of keystrokes.

They say these patterns are unique to different typists and could lead to a new type of biometric security, locking out anyone who doesn't type like you do.

The keyboard can also power itself using something called contact electrification.

It generates current when your fingertips touch the keys, which are coated with an electrode material.

So we're talking about a wireless keypad that never needs batteries.

The researchers published a paper about their intelligent keyboard in the journal ACS Nano.

Maybe the best feature of the keyboard is that it's basically made from layers of plastic and has no mechanical keys.

That means you could drop crumbs or even spill coffee on it without any damage—forget voice recognition, now you're talking!
