专四听力第二题的意思如下∶在这一节你将听到两段长对话。在每段对话结束时你会听到四个问题，对话和问题都只讲一次。在你听到一个问题后，你必须从标有ABC和D的四个选项中选择一个最佳答案，然后在答案中用单线划出相应的字母。
Glaciers are slowly moving masses of ice that have accumulated on land in areas where moresnowfalls during a year than melts. Snow falls as hexagonal crystals, but once on the ground,snow is soon transformed into a compacted mass of smaller, rounded grains. As the air spacearound them is lessened by compaction and melting, the grains become denser. With furthermelting, refreezing, and increased weight from newer snowfall above, the snow reaches agranular recrystallized stage intermediate between flakes and ice known as firn. With additionaltime, pressure, and refrozen meltwater from above, the small firn granules become larger,interlocked crystals of blue glacial ice. When the ice is thick enough, usually over 30 meters,the weight of the snow and firn will cause the ice crystals toward the bottom to become plasticand to flow outward or downward from the area of snow accumulation.
Glaciers are open systems, with snow as the system’s input and meltwater as the system’smain output. The glacial system is governed by two basic climatic variables: precipitation andtemperature. For a glacier to grow or maintain its mass, there must be sufficient snowfall tomatch or exceed the annual loss through melting, evaporation, and calving, which occurswhen the glacier loses solid chunks as icebergs to the sea or to large lakes. If summertemperatures are high for too long, then all the snowfall from the previous winter will melt.Surplus snowfall is essential for a glacier to develop. A surplus allows snow to accumulateand for the pressure of snow accumulated over the years to transform buried snow intoglacial ice with a depth great enough for the ice to flow. Glaciers are sometimes classified bytemperature as faster-flowing temperate glaciers or as slower-flowing polar glaciers.
Glaciers are part of Earth’s hydrologic cycle and are second only to the oceans in the totalamount of water contained. About 2 percent of Earth’s water is currently frozen as ice. Twopercent may be a deceiving figure, however, since over 80 percent of the world’s freshwater islocked up as ice in glaciers, with the majority of it in Antarctica. The total amount of ice is evenmore awesome if we estimate the water released upon the hypothetical melting of the world’sglaciers. Sea level would rise about 60 meters. This would change the geography of the planetconsiderably. In contrast, should another ice age occur, sea level would drop drastically. Duringthe last ice age, sea level dropped about 120 meters.
When snowfalls on high mountains or in polar regions, it may become part of the glacialsystem. Unlike rain, which returns rapidly to the sea or atmosphere, the snow that becomespart of a glacier is involved in a much more slowly cycling system. Here water may be stored inice form for hundreds or even hundreds of thousands of years before being released again intothe liquid water system as meltwater. In the meantime, however, this ice is not static. Glaciersmove slowly across the land with tremendous energy, carving into even the hardest rockformations and thereby reshaping the landscape as they engulf, push, drag, and finallydeposit rock debris in places far from its original location. As a result, glaciers create a greatvariety of landforms that remain long after the surface is released from its icy covering.
Throughout most of Earth’s history, glaciers did not exist, but at the present time about 10percent of Earth’s land surface is covered by glaciers. Present-day glaciers are found inAntarctica, in Greenland, and at high elevations on all the continents except Australia. In therecent past, from about 2.4 million to about 10,000 years ago, nearly a third of Earth’s landarea was periodically covered by ice thousands of meters thick. In the much more distant past,other ice ages have occurred.
多听多练。冲击波的有本专四听写50篇，那本还可以，语速和难度接近真题。还有就是多听多练10年真题的dictation，毕竟是真题嘛。而且陈汉生的专四指南也要多练（虽然里面的语速偏快）。
dictation听第一遍的时候一定要注意听大意，理解文章，不要急着写；听第二遍的时候尽量都写出来，每句话至少要写出70%；第三遍的时候要注意听第二遍时没有听清或写请的句子、单词、短语（值得注意的是，听写的时候最好是听完一个句子后或者一个意群后再开始动笔写，否则很容易写了前半句忘了后半句）；第四遍时就要开始检查了，着重听弱读、连读之类的单词、短语。最后两分钟的检查时间也很重要，检查单词拼写错误、语法错误、标点符号以及在写的时候是否有笔误。
其实实际考试的时候dictation的选文还是比较简单的，贴近考生生活，考生较为容易理解。而且dictation的语速也不是很快，每个意群断句也比较短。改卷的时候这部分改的好像不是很严，我是09年考的，这部分的分数比我自己估分要高多了。反正多听多练就可以了，你们听力老师那应该也有很多dictation练习材料的，考前每天一篇，考试时就没有什么大问题了
教授不是出了本真题集吗QAQ才二十多块！！！不过教授说印量有限，也不知道亚马逊上还有没有，我只买了本专八的，2012 年的没有，这里附上：

在07-15年。07-15年，是专四的稳定期，出题风格相差无几，thestudioschool的听力原文在这几年找就可以。
晕。。我一不小心半夜没睡点进来一看发现楼主的昵称怎么这么熟悉。。回去调过回答问题一看原来上个星期要2007年日语专业四级的也是你。。。囧
-----------------
这个真是爱莫能助了。。真的 我估计也没有人能帮你
网上日语专四的资料少是有原因的——专四的社会认知度实在是太低了。也就是说专四的证书根本没什么用。
所以我的建议是，楼主既然有07年的真题了，其实只要做做07的知道一下题型就可以了。其他的都不重要。如果真要想练习那就做国际能力考试的二级，比日语专四稍微难一点点，我觉得非常适合你。
楼主，哥都看不下去了，劝你别这么执着于日语专四了，完全没用。
---------------
如果要日语二级或者一级的资料，还是上次那个邮箱loiuve@qq.com，资料多到你看不过来。专四我就07的给你找了半天算是找到了，08 09的刚刚也找了半天找不到。如果你一定要的话只能去买书了。
十年的听力真题，加上MP3，文件体积十分巨大，发到邮箱太耗时了还占空间，不如你自己去下载一下，很方便的，在全国英语专业四八级考试的官方网站“四八级在线”的论坛中，是“新四军培训班集结号”这个版块下面的帖子，名称分别叫：

1999-2007年英语专业四级考试全真试题+答案
下载收看1997-2009年英语专业四级真题试卷
我刚才看到这三个帖子都在“新四军培训班集结号”的第三页里面，你找找看吧，这个官网的首页还有历年四八级阅卷老师对真题的视频实例讲解,对于高效备考大有帮助,祝你明年成功!
