语言点精讲
1.It’s higher than any other mountain.它比任何一座山都高。(Grammar Focus)
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。
同一范围内比较，other必不可少，用以将主语从比较对象中排除，避免逻辑重复矛盾。
She is thinner than any other student in her class. = She is the thinnest in her class.
【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.
Hulunbuir is bigger than any other city in China.
Hulunbuir is bigger than any city in Anhui.
2.The Amazon River is one of the longest rivers in the world.亚马逊河是世界上最长的河流之一。（4a）
It’s one of the most popular places for serious mountain climbers. 这里是最受登山爱好者欢迎的地方之一。（4a）
两句中都有one of …结构，意为，…之一。one of 后面常常跟形容词最高级和名词复数形式。“one of +the +形容词最高级+名词复数”是英语中最高级的固定搭配。表示“……是……中最……之一”。
She is one of the tallest girls in our school.
The Yellow River is one of the longest rivers in China.
3.No ocean in the world is as big as the Pacific Ocean.世界上没有一个海洋像太平洋那么大。（4a）
…as +原级 +as … “和…一样”
你和我一样高。You are as tall as me.
Lily和Lucy 跑的一样快。Lily runs as fast as Lucy.
否定形式…not so\as +原级 +as … “前者不如后者”
你不如我高。You are not so\as tall as me.
Lily跑得不如Lucy快。Lily doesn’t run so\as fast as Lucy.
该句中的no ocean,可以理解为any ocean…not
上句可以写成：Any ocean in the world is not as big as the Pacific Ocean.世界上任何海洋都不如太平洋大。这也是原级表达最高级的意思。The Pacific Ocean is the biggest ocean in the world.
