Pst-listening
【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-lng rpe isn’t lng enugh t help climb the muntain.
2. Qmlangma is higher than any ther muntain in the wrld. (教材 P49 1b)
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 ther student in her class. = She is the thinnest in her class.
ther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 wrld.
Hulunbuir is bigger than _____________ city in China.Hulunbuir is bigger than _____________ city in Anhui.
