2. Qomolangma is higher than any other mountain in the world. (教材 P49 1b)
Post-listening
比较级 + than any other + 可数名词单数
Point
该结构意为“比其他任何一个……都……”，指同一范围内比较，表示最高级含义。
She is thinner than any other student in her class. = She is the thinnest in her class.
other必不可少，用以将主语从比较对象中排除，避免逻辑矛盾。
Post-listening
【特别提醒】如果比较对象不在同一范围内或不属于同一类别，应用“形容词/副词比较级 + than any（任何的） + 可数名词单数”。
The Pacific Ocean is larger than any lake in the world.
