1、這些托福聽力備考的學(xué)習(xí)建議你都知道嗎 這些托福聽力備考的學(xué)習(xí)建議你都知道嗎?聽不懂一定要看原文練習(xí)過程中對于*或段子聽不懂是否應(yīng)該硬聽，直到聽懂為止呢?否，千萬不要這樣做，聽3到5遍之后，若發(fā)現(xiàn)聽不懂應(yīng)馬上看原文才是正確做法。但看過原文之后應(yīng)該反復(fù)聽，直到聽到關(guān)鍵詞都能夠大腦條件反射，做到不用想也能知道記住。對于聽力而言，反復(fù)聽已聽懂的要比聽聽不懂的重要的多，同時效果也好很多。因為當(dāng)你聽不懂而去翻原文時很少是因為單詞不認(rèn)識耳聽不懂，大多是熟詞但出現(xiàn)場合改變所造成的。聽力素材反復(fù)聽十遍在考試前一定要把所有的聽力過一遍，可能要花兩天時間。你可以一邊做事一邊聽，要求是你一聽到小段子，你就知道答案是什

2、么，是考事件，還是時間，或人物!這段子的重點是想考你什么。同時培養(yǎng)耳朵和大腦的條件反射。這樣會使你在考試時能夠在心態(tài)起伏之前就聽出答案，這對于大家穩(wěn)定和提升考場表現(xiàn)是很有好處的。要學(xué)會帶著問題去聽帶著問題去聽，會使你聽力一聽完，就能直接找到答案。而且也可以幫助大家有選擇的去聽取需要的信息，這個技巧在面對長*時是非常有效率的?？忌瓤?的題目，再看答案，把*的內(nèi)容和重點先有所了解，而且要有對答案，*的問題提法有所猜測，把自己的猜測和實際聽力去對比，你會發(fā)現(xiàn)聽力講的事你有所了解的事情，而且有過思考的事，這樣化被動為主動，是很有幫助的。大家要能夠使自己的猜測準(zhǔn)確，就需要平時的多聽，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.如果你問別人青蛙的叫聲是什么樣，得到的答案可能會是呱呱聲。但只有一種青蛙會發(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通過發(fā)送信號進(jìn)行交流。假如你是一只雄性巴西湍蛙。青蛙的信號.gif而且你在亞馬遜叢林激流邊生活。你對周圍生活的雌性快樂的發(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。這種鮮明的對比色會將你的身體變成警示色。收到這種訊號的入侵者就會跳走去打擾別人。巴西動物學(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。他和同事們在公共科學(xué)圖書館雜志上發(fā)表了這項研究結(jié)果。由于河流湍急，青蛙的信號系統(tǒng)可能會因此進(jìn)化。這些青蛙不再用嘹亮的歌聲喊過湍急

10、的河流，而是通過跳躍，晃動頭部，擺動手臂或甚至搖擺腳趾等方式交流。這種信號是蛙類研究中有記載以來最為復(fù)雜的方式，但德薩認(rèn)為只要研究人員們肯花時間觀察就會發(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話，讓他給我打個電話。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.我想我得停下來了
