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. 2. 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. 练一练 ①Hulunbuir is bigger than any other city in China. ②Hulunbuir is bigger than any city in Anhui.
