第4、5、6、7、8题:T[ornadoes,whirlwinds,and watersprouts are rotating funnel cloud air masses of small diameter.They are differentiated by the intensity of their rotation and by the surfaces that they traverse.Though tornadoes and whirlwinds both travel over land masses,whirlwinds are atmospheric systems smaller than tornadoes.Watersprouts are tornadoes that form or pass over a water surface.A tornado is a powerful vortex or “twister” whose rotational speeds are estimated to be near 300 miles per hour.The first visible indication of tornado development is usually a funnel cloud.As this funnel dips earthward,it becomes darker because of the debris that is forced into its intensifying vortex.Some tornadoes give no visible warning until their destruction strikes the unsuspecting victim.Tornadoes often occur in groups,and several twisters sometimes descend from the same cloud base.The forward speed of a tornado is normally 30 to 40 miles per hour.In the short time that it takes to pass,a tornado can cause fantastic destruction.There have been cases reported in which blades of straw were embeded in fence posts. 31. How are tornadoes distinguished from whirlwinds? A.Whirlwinds rotate in a different direction than tornadoes do. B.Tonadoes travel over land and whirlwinds over water.

第17、18、19、20、21题:Icebergs are among nature's most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being-somewhere-in faraway, line frigid waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees. They exist only a short time and then slowly away just as unnoticed. Objects of sheerest beauty, they have been called. Appearing in an endless variety of shapes, they may be dazzlingly white, or they may be glassy blue, green, or purple, tinted faintly or in darker hues. They are graceful, stately, inspiring-in calm, sunlit seas. But they are also called frightening and dangerous, and that they are in the night, in the fog, and in storms. Even in clear weather one is wise to stay at a safe distance away from them. Most of their bilk is hidden below the visible top. Also, they may roll over unexpectedly, churning the waters around them. Icebergs are parts of glaciers that break off, drift into the water, float about a while, and finally melt. Iceberg afloat today are made of anowflakes 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 year ago. The snows fell in polar regions 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 fell on the 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. 46. Which of the following is the best title for the passage? A. The Name and Origin of Icebergs B. The Size and Shape of Icebergs C. The Dangers of icebergs D. The melting of Icebergs 47.
