【语篇解读】 本文为说明文。文章主要说明冰山的一些特点以及注意事项。1．masses 考查固定搭配。句意：冰山是冰川或极地冰盖上破碎的大量淡水冰。masses f 为固定搭配，意为“许多的，大量的”，故填masses。2．seen 考查过去分词作定语。句意：今天看到的冰山始于数千年前。分析句子可知，空格处在句中作定语，因为Icebergs 和动词see二者是逻辑上的动宾关系，要用过去分词作后置定语，故填seen。3．the 考查冠词。句意：底部的雪被压碎了。此处是特指底部的雪，要用定冠词，故填the 。4．melting 考查动词的ing形式作宾语。句意：多年的融化和冰冻形成了数千英尺厚的冰层。分析可知，f为介词，后面要用动词的ing形式，故填melting 。
5．and 考查语境及连词。句意：在春天和夏天比较暖和的时候，冰川上的冰块会脱落。句中的spring和summer二者是并列的，故填and。6．in 考查固定用法。句意：冰山大小不一。in size为固定搭配，意为“在大小上，尺寸上”。故填in 。7．tallest 考查最高级。句意：最高的冰山高出海洋550英尺。根据语境可知，此处是指最高级，可知要填tallest 。8．dangerus 考查形容词作表语。句意：冰山对于在它们附近航行的船只来说是非常危险的。分析句子可知，此处是形容词做表语，故填dangerus 。
9．is 考查谓语动词。句意：因为只有八分之一的冰山露出水面。主语neeighthfaniceberg是单数。结合上下文，使用一般现在时，故填is 。10．their 考查代词。句意：船长驾驶他们的船绕过一座冰山时可能会误估冰山的大小。修饰名词ships，要用形容词性物主代词，他们的船只，故填their。
