本聽力材料來自于老托partb，partc，是公認實施有效的聽寫材料，對于上手托福時間不長的同學非常適合。我曾經一次短時間備考聽力提高了7分也歸功老托。希望大家和我一樣一定要堅持下來噢。相信堅持學習的同學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鍵詞，回復后即可看到聽力原文和文章精解，我將把難點和易錯點oneby one 分析給大家。

The most common way to observe the skies is to photograph them. The process is very simple. First, a ______ ______is ______with a ______material. The plate is ______so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged, and published so that many people can study it.
