本聽力材料來(lái)自于老托partb，partc，是公認(rèn)實(shí)施有效的聽寫材料，對(duì)于上手托福時(shí)間不長(zhǎng)的同學(xué)非常適合。我曾經(jīng)一次短時(shí)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(jiān)持下來(lái)噢。相信堅(jiān)持學(xué)習(xí)的同學(xué)聽力上都會(huì)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(shí)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(diǎn)和易錯(cuò)點(diǎn)oneby one 分析給大家。
回復(fù)填空答案格式如下：1____2____3____...et.al.
Today I want to talk about the Earth's last major____shift, at the end of the last______. But first, let's back up a moment and review what we know about climatic change in general. First, we defined"climate" as_____patterns of weather over significant periodsof time. In general, changes in climate occur when the energy balance of the Earth is______.Solar energy enters the Earth's atmosphere as light and is______by the Earth's surface asheat. Land, water, and ice each affect this energy exchange differently. Thesystem is so complex that, to date, our best computer models are only______________and are not sophisticated enough to test______about the causes of climatic change. Ofcourse, that doesn't keep us from_______. For instance, volcanic activity is one mechanism that might affect climatic change. When large volcanoes erupt, they______tons of particles into the upper atmosphere, where the particles then reflectlight. Since less light is entering the system of energy exchange, the resultwould be a_______of the Earth's surface. Of course, this is just one possible mechanism of global climate change. In all probability, a complete explanation would involve several different mechanisms operating at the same time.
