Hola,大家好，我是AmyLee，第一次跟大家見面，以后就由我來負(fù)責(zé)老托福聽力的講解。該材料來自于老托partb，partc，是公認(rèn)實施有效的聽寫材料，對于上手托福時間不長的同學(xué)非常適合。我曾經(jīng)一次短時間備考聽力提高了7分也歸功老托。今天是第一天，希望大家和我一樣一定要堅持下來噢。相信堅持學(xué)習(xí)的同學(xué)聽力上都會有很大的飛躍。

Nopain, no gain.我們的安排是這樣的，第一遍用聽力軟件精聽材料（建議做單句聽寫，聽寫的時候不要偷看我給的挖空題），然后按照我給的挖空題填關(guān)鍵詞，回復(fù)后即可看到聽力原文和文章精解，我將把難點和易錯點one by one分析給大家。

回復(fù)填空答案格式如下：1____2____3____...et.al.
