Paragraph1: Glaciers are slowly moving masses of ice that have accumulated on land in areas where more snowfalls during a year than melts. Snowfalls as hexagonal crystals, but once on the ground, snow is soon transformed into a compacted mass of smaller, rounded grains. As the air space around them is lessened by compaction and melting, the grains become denser. With further melting, refreezing, and increased weight from newer snowfall above, the snow reaches a granular recrystallized stage intermediate between flakes and ice known as firn. With additional time, 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 plastic and to flow outward or downward from the area of snow accumulation.

2. According to paragraph 1, which of the following does NOT describe a stage in the development of firn?    A
○Hexagonal crystals become larger and interlock to form a thick layer.
Not题特征， 互换！！！！交叉，不是雪花变大！！！！
○Snow crystals become compacted into grains.
○Granules recrystallize after melting, refreezing, and further compaction.
○Grains become denser owing to reduced air space around them.误以为这个文章没有提到，不可以凭感觉!!!!!!!
