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。
回復填空答案格式如下：1____2____3____...et.al.
Most people think of astronomers as people who spend their time in cold______through telescopes every night. In fact, a typical astronomer spends most of his or her time analyzing data and may only be at the telescope a few weeks of the year. Some astronomers work on purely_____problems and never use a telescope at all. You might not know how rarely images are viewed directly through telescopes. 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. Because most astronomical objects are very remote, the light we receive from them is rather______. But by using a telescope as a camera, long time exposures can be made. In this way, objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.
