本听力材料来自于老托partb,partc,是公认实施有效的听写材料,对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃!

Nopain, no gain.我们的安排是这样的,第一遍用听力软件精听材料(建议做单句听写,听写的时候不要偷看我给的挖空题),然后按照我给的挖空题填关键词,回复后即可看到听力原文和文章精解,我将把难点和易错点oneby one 分析给大家。

回复填空答案格式如下: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.
