注意：在句子中，形容词最高级前面要加the。

三者或三者以上比较，表示“最……的”常用“the +形容词最高级”结构，后跟由f或in开头的表示范围的介词短语。
例句：Lucy is the tallest f the three.
Key sentence: It's taller than bth f us tgether.
形容词有原级、比较级、和最高级三个等级，比较级通常用于两个人/物间的比较。than意为“比”
句型结构：A +be动词+形容词比较级+than+B.
例句：Jack is taller than Tm.
我们学会了如何来比较两个人或事物，但是当比较有具体的差距时，如短2厘米、大3岁等，该如何表达呢？来看下面的句型公式吧。
A + + + + +B.
例句：I'm 5 years lder than my sister.
Key sentence: —Hw tall are yu? —I'm 1.65 metres.

例句：—Hw tall are yu? —I'm 1.5 metres. —Hw tall is Jhn? —He is 1.6 metres.
be动词随着主语人称的变化而变化;在表达高度时，后面的tall可省略，长度超过1时，要用复数。
