Language points
1. 长、宽、高、深、面积的表达方法
The river is 20 meters wide. = The river is 20 meters in width.
基数词 + 单位词 + 形容词(long, wide, high, deep等)
基数词 + 单位词 + in + 名词(length, width, height, depth, size等)
【拓展延伸】作定语时用合成词“数词 - 单位词单数- 形容词”。
This 20-meter-long rope isn’t long enough to help climb the mountain.
2. Qomolangma is higher than any other mountain in the world.
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。
比较级 + than any other + 可数名词单数
【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.
