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.
Since we've been discussing alternative fuels lately, I wanted to pass onto you some information I read about a new fuel that's been in the news a lot lately. It's called A-21.It's ______ of water and a chemical known as ______. It seems to be avery promising fuel because it's much cleaner than the ______ that we usetoday. That's not to say that it doesn't pollute, but it is cleaner. A-21 isn'tlike some other alternative fuels that require completely new types of engines.A-21 still works in regular, everyday ______ engines --- like the ones incars --- with only minor mechanical modifications. So changing over wouldn't bea big deal.You may doubt some of these claims as many researchers have. Some people feared that because it contains about 45 percent water it would freeze in the winter. But a small amount of ______ was added to it, and that seems tohave solved the problem.A-21 has recently undergone street tests in buses in Reno, Nevada. So far it seems to work just fine. This is a good thing, especially in Nevada, because the state government there has passed a law requiring that a large percent age of vehicles in Nevada run on alternative fuels. A-21 should help.
