第9题：
1. Icebergs are among nature's most spectacular（壮观的）creations , and yet most people have never seen one.A vague air of mystery envelops them.They come into being somewhere in faraway, frigid waters,amid thunderous noise and splashing turbulence,which in most case no one hears or sees. They exist only a short time and then slowly waste away（消融）just as unnoticed.
2. Objects of sheerest（最纯粹的）beauty they have been called. Appearing in an endless vaniety of shapes,they may be dazzlingly white,or they may be glassy blue,green or purple,tinted faintly on in darker hues.They are graceful, stately,inspiring in calm,sunlight seas.
3.But they are also called frightening and dangerous,and that they are一in the night,in the fog,and in storms.Even in clear weather one is wise to stay a safe distance away from them.Most of their bulk is hidden below the water,so their underwater parts may extend out far beyond the visible top.Also,they may roll over unexpectedly,churning the waters around them.
4.Icebergs are parts of glaciers that break off,drift into the water,float about awhile,and finally melt.Icebergs afloat today are made of snowflakes that have fallen over long ages of time.They embody snows that drifted down hundreds,or many thousands,or in some cases maybe a million years ago.The snows fell in polar region and on cold mountains,where they melted only a little or not at all,and so collected to great depths over the years and centuries.As each year's snow accumulation lay on the surface,evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice.When new snow fell on top of the old,it too turned to icy grains.So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones.With time and pressure from above, the many small ice grains joined and changed to larger crystals,and eventually the deeper crystals merged into a solid mass of ice.
A:larger than the part above the water
B:stay near the iceberg
C:melt away just as unnoticed
D:larger crystals
E:stay away from iceberg
F:above the water
第二段讲冰山的美。C项是干扰项。第二段提到了冰山的不同颜色，但描写颜色的目的是为了体现它的美。另外，本段第一句“Objects of sheerest beauty they have been called.”和最后一句“They are graceful , stately , inspiring in calm , sunlight seas.”也都在讲冰山的美丽。
第三段讲冰山是很危险的。第一句就提到：" But they are also called fright-ening and dangerous…”。
第四段讲冰山是如何形成的。
第一段最后一句：" They exist only a short time and then slowly waste away just as unnoticed." waste away和melt away都有“慢慢消融”的意思。
答案相关句在第三段第二句：" Even in clear weather one is wise to stay a safe distance away from them."
答案相关句在第三段第三句：" Most of their bulk is hidden below the water, so their underwater parts may extend out far beyond the visible top."
问题句空格处需要填名词性短语。D项是选项中唯一的名词性短语。另外，从文章的最后一句“With time and pressure from above , the many small ice grains joined and changed to larger crystals , and eventually the deeper crystals merged into a solid mass of ice.”也能找到答案。
