describe them.

Helen has the longest hair in the class.
Step 3 Language points learning
1. 长、宽、高、深、面积的表达方法
①基数词 + 单位词 + 形容词（long, wide, high, deep等）
②基数词 + 单位词 + in + 名词（length, width, height, depth, size等）
The river is 20 meters wide. = The river is 20 meters in width.
【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.
42. Qomolangma is higher than any other mountain in the world.
比较级 + than any other + 可数名词单数
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.
注意：other必不可少，用以将主语从比较对象中排除，避免逻辑矛盾。
【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.
