问题     Icebergs are among nature’s most spectacular creations, and yet most people have never seen one. A vague air of mystery【C1】______them. They come into being—somewhere—in faraway, 【C2】______cold waters, amid thunderous noise and splashing【C3】______, which in most cases no one hears or sees. They exist only a short time【C4】______then slowly melt away just as unnoticed.
    They have been【C5】______objects of sheerest beauty. Appearing in an endless【C6】______of shapes, they may be dazzlingly white, or they may be glassy blue,green or purple, stained【C7】______or in darker hues (色彩).They are graceful, stately, inspiring in calm, sunlit seas.
    But they are also called【C8】______and dangerous, and they are—in the night, in the fog, and in storms. 【C9】______in clear weather one is wise to stay a safe distance【C10】______from them. Most of their【C11】______is hidden below the water, so their underwater parts may extend out far【C12】______the visible top. Also, they may roll o-ver unexpectedly, churning (搅动) the water around them.
    Icebergs are parts of glaciers (冰川) that break off, drift into the water, float about【C13】______, and finally waste away. Icebergs afloat today are【C14】______of snowflakes that have fallen over long ages of time. They【C15】______snows that drifted down hundreds or many thousands years ago. The snows fell in【C16】______regions and on cold mountains, where they wasted away only a little or not at all, and so collected to great depths over the years and centuries.
    【C17】______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 also【C18】______into ice 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【C19】______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【C20】______a solid mass of ice.
【C9】
选项 A、Then
B、Indeed
C、Even
D、Always
答案C
解析 副词辨义。本句意为“即便是在晴朗的天气里，与它们保持一段安全距离也是明智的”。因此，选C)even“即使，甚至”。A)then“然后；那么；于是”；B)indeed“的确；实在；真正地”；D)always“一直”。根据上面提到的night，fog和storm和后面的clear weather可知，此处语气进行了转折，而此三项均不能表达语气的转折，故可以排除。
