◇ Comparatives: as + adj. + as
比較級：as + 形容詞 + as
as…as 的句型可以拿來比較兩樣事物，表達程度相當的意思。With temperatures reaching a whopping 122 degrees and humidity as high as 80—100%, it's a wonder that people survived before the invention of air conditioning! （在華氏 122 度 (攝氏 50 度) 的高溫下，加上濕度高達 80-100%，人類之前竟然能在沒冷氣的狀況下存活，真是個奇蹟。） 這句就是在表達，「濕度和80-100%一樣高」的概念。
