【◆答案解析◆】:【原文大意】永远也不要在大雪覆盖的山上大笑!在雪崩的季节,大笑和大喊都会引起惨重的雪崩。在山上被雪和冰覆盖的陡坡最容易产生大块雪的滑动。雪慢慢地集中起来,轻轻地落下,造成非常敏感且不稳定的态势。数吨的雪可能仅靠雪花之间的摩擦支撑。深深的雪如同纸牌搭的房子,最轻微的活动都会使它倒塌。一旦有东西滑动,巨大的雪块就会冲下山坡。声波会引起滑动,湿的、溶化的雪的重量也可能引起滑动。一旦雪崩产生,其产生的原因就不再重要了。雪崩冲下陡坡,速度在加快,卷入更多的雪。有些雪崩的速度相当于每小时200英里的速度。它的力量可以摧毁沿途的一切。整个的房子被这些急速的雪堆吞噬。由雪崩引起的风几乎同雪崩自身一样是毁灭性的。这些风的速度可与飓风匹敌。因此,当靠近大雪覆盖的大山时,轻声说话!第二段。下雪本身并不能引起雪崩。最后一段说雪崩可引起风,而不是风引起雪崩。雪花之间的摩擦说明积雪不牢固。只有选项c是正确的。

【◆参考答案◆】:D
