(1)【◆题库问题◆】：[单选] 回答{TSE}题Never laugh at a snow covered mountain!Laughter and yelling, during the avalanche season, can cause a deadly pile ofsnow．Huge snow slides are most common in mountains where there are steep slopesthat are well buried in snow and icE．The snow builds up slowly and lands verysoftly．This can create a very touchy, unstable situation．Tons of snowmay be held up by only the friction between snowflakes．The deep snow is like ahouse of cards．The slightest movement can cause it to fall．As soon assomething slips, this great mass of snow will come crashing down themountainsidE．Slides may be started by sound vibrations．They may also be started by the weight of wet, melting snow．Once an avalanchehas been triggered, the cause no longer matters．Moving down a steep slope, itpicks up great speed and added snow．Some avalanches travel as fast as twohundred miles per hour．The force of an avalanche will mow down anything in itspath．Whole houses have been swallowed up by these fast-paced piles of snow．Thewind that is caused by an avalanche is almost as destructive as the snowitselF．Winds from an avalanche have been known to travel as fast as those of atornado．So, when approaching a thicklysnow covered mountain, speak softly!{TS}Avalanches can be started by________
A．falling snow
B．the wind
C．loud sounds
D．friction between snowflakes

【◆参考答案◆】：C

【◆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。

(2)【◆题库问题◆】：[单选] 函数y=ex-x在区间(-1，1)内（　　）.
A．单调减少
B．单调增加
C．不增不减
D．有增有减

【◆参考答案◆】：D

【◆答案解析◆】：本题需先求出函数的驻点，再用y″来判定是极大值点还是极小值点，若是极值点，则在极值点两侧的yˊ必异号，从而进一步确定选项．因为yˊ=ex-1，令yˊ=0，得x=0．又y″=ex>0，x∈(-1，1)，且y″|x=0=1>0，所以x=0为极小值点，故在x=0的左、右两侧的函数必为由减到增，则当x∈(-1，1)时，函数有增有减，所以应选D．
