1、這些托福聽(tīng)力備考的學(xué)習(xí)建議你都知道嗎 這些托福聽(tīng)力備考的學(xué)習(xí)建議你都知道嗎?聽(tīng)不懂一定要看原文練習(xí)過(guò)程中對(duì)于*或段子聽(tīng)不懂是否應(yīng)該硬聽(tīng)，直到聽(tīng)懂為止呢?否，千萬(wàn)不要這樣做，聽(tīng)3到5遍之后，若發(fā)現(xiàn)聽(tīng)不懂應(yīng)馬上看原文才是正確做法。但看過(guò)原文之后應(yīng)該反復(fù)聽(tīng)，直到聽(tīng)到關(guān)鍵詞都能夠大腦條件反射，做到不用想也能知道記住。對(duì)于聽(tīng)力而言，反復(fù)聽(tīng)已聽(tīng)懂的要比聽(tīng)聽(tīng)不懂的重要的多，同時(shí)效果也好很多。因?yàn)楫?dāng)你聽(tīng)不懂而去翻原文時(shí)很少是因?yàn)閱卧~不認(rèn)識(shí)耳聽(tīng)不懂，大多是熟詞但出現(xiàn)場(chǎng)合改變所造成的。聽(tīng)力素材反復(fù)聽(tīng)十遍在考試前一定要把所有的聽(tīng)力過(guò)一遍，可能要花兩天時(shí)間。你可以一邊做事一邊聽(tīng)，要求是你一聽(tīng)到小段子，你就知道答案是什

2、么，是考事件，還是時(shí)間，或人物!這段子的重點(diǎn)是想考你什么。同時(shí)培養(yǎng)耳朵和大腦的條件反射。這樣會(huì)使你在考試時(shí)能夠在心態(tài)起伏之前就聽(tīng)出答案，這對(duì)于大家穩(wěn)定和提升考場(chǎng)表現(xiàn)是很有好處的。要學(xué)會(huì)帶著問(wèn)題去聽(tīng)?zhēng)е鴨?wèn)題去聽(tīng)，會(huì)使你聽(tīng)力一聽(tīng)完，就能直接找到答案。而且也可以幫助大家有選擇的去聽(tīng)取需要的信息，這個(gè)技巧在面對(duì)長(zhǎng)*時(shí)是非常有效率的?？忌瓤?的題目，再看答案，把*的內(nèi)容和重點(diǎn)先有所了解，而且要有對(duì)答案，*的問(wèn)題提法有所猜測(cè)，把自己的猜測(cè)和實(shí)際聽(tīng)力去對(duì)比，你會(huì)發(fā)現(xiàn)聽(tīng)力講的事你有所了解的事情，而且有過(guò)思考的事，這樣化被動(dòng)為主動(dòng)，是很有幫助的。大家要能夠使自己的猜測(cè)準(zhǔn)確，就需要平時(shí)的多聽(tīng)，多練，多想。除了練

8、hat other frogs could have similarly complex repertoires, if only researchers would take the time to look.one thing is certain: its not easy being green, but its simple to be seen.如果你問(wèn)別人青蛙的叫聲是什么樣，得到的答案可能會(huì)是呱呱聲。但只有一種青蛙會(huì)發(fā)出這樣的叫聲，那就是太平洋合唱哇。由于碰巧居住在好萊塢的聲音藝術(shù)家附近，因此這種青蛙的叫聲就顯得非常獨(dú)特。爬蟲學(xué)家很早以前就已知曉青蛙的叫聲不只呱呱，而且又多種多樣

9、的叫聲。但青蛙的交流方式除了叫聲外還有多種形式它們彼此之間也會(huì)通過(guò)發(fā)送信號(hào)進(jìn)行交流。假如你是一只雄性巴西湍蛙。青蛙的信號(hào).gif而且你在亞馬遜叢林激流邊生活。你對(duì)周圍生活的雌性快樂(lè)的發(fā)出吸引的叫聲。但當(dāng)其它雄性逐漸靠近，你的叫聲馬上變?yōu)檫筮蠹饨小＿@時(shí)你就在自己的奶白色臉前揮舞紅褐色的手臂。這種鮮明的對(duì)比色會(huì)將你的身體變成警示色。收到這種訊號(hào)的入侵者就會(huì)跳走去打擾別人。巴西動(dòng)物學(xué)家法比奧德薩就曾親眼目睹巴西湍蛙使用18種不同的可視信息，而其中5種在其它青蛙中從未出現(xiàn)過(guò)。他和同事們?cè)诠部茖W(xué)圖書館雜志上發(fā)表了這項(xiàng)研究結(jié)果。由于河流湍急，青蛙的信號(hào)系統(tǒng)可能會(huì)因此進(jìn)化。這些青蛙不再用嘹亮的歌聲喊過(guò)湍急

10、的河流，而是通過(guò)跳躍，晃動(dòng)頭部，擺動(dòng)手臂或甚至搖擺腳趾等方式交流。這種信號(hào)是蛙類研究中有記載以來(lái)最為復(fù)雜的方式，但德薩認(rèn)為只要研究人員們肯花時(shí)間觀察就會(huì)發(fā)現(xiàn)其它種類的青蛙或許有著同樣復(fù)雜的行為方式。而能夠確認(rèn)的一件事情是，變綠不易，但不難被發(fā)現(xiàn)。1.happen to 偶然;發(fā)生例句:if you happen to talk to him, have him call me.如果你碰巧能和他說(shuō)話，讓他給我打個(gè)電話。2.turn into 轉(zhuǎn)化為;轉(zhuǎn)變;變?yōu)槔?i think i have got to stop or i might turn into a machine.我想我得停下來(lái)了

11、，否則我就會(huì)變成一臺(tái)機(jī)器。3.instead of 而不是例句:the farmers will be paid for their grain in cash, instead of ious.農(nóng)民賣糧，將以現(xiàn)金支付，而不是白條了。4.shout over 喊過(guò)例句:the painest tear shout over graves after the words left unsaid and dids left undone.最痛苦的淚水從墳?zāi)估锪鞒?，為了還沒(méi)有說(shuō)過(guò)的話和還沒(méi)做過(guò)的事。2020托福聽(tīng)力練習(xí)：氣候變化影響美西南部針葉林as you sit round the christ
