【参考范文】The little boy headed back down to the old man's house. The thought of knocking at the oldman's door filled the little boy with fear, but he still knocked on the door, waiting breathlesslyFinally, it opened, and out came the old man.

11.B【解析】根据题目描述:X有两种常见的同素异形体,其中一种可用于饮用水杀菌、漂白,氧元素有两种常见的同素异形体(O2和O3),O3可用于饮用水杀菌、漂白,则X为O,Z的单质是芯片的主要成分,Z为Si,W的原子序数最大,且原子半径是同周期主族元素中最小的,W为C,Y、Z的最外层电子数之和等于W的最外层电子数,则Y的最外层电子数为7-4=3,Y的原子序数又大于X,则Y为Al。则X、Y、Z、W依次为O、Al、Si、Cl。Si与O形成的化合物SiO2熔点很高,且不可燃烧,可用作耐高温材料,Si与Cl形成的化合物siCl4熔点较低,不能作耐高温材料,A项错误;Al与O形成的化合物Al2O3熔融态可以导电,属于电解质,A与Cl形成的化合物AlCl3虽是共价化合物,但溶于水可以导电,属于电解质,B项正确;元素的非金属性越强,对应的简单氢化物的热稳定性越好,非金属性:CD>Si,则热稳定性:HC>SiH;,C项错误;单质Si与冷的浓硫酸不反应,单质A遇到冷的浓硫酸会钝化,发生了化学反应,D项错误。
