4．“A ＋ be ＋ the ＋ 比较级＋ of the two(＋复数名词)”表示“A是两者中比较……的”。如：
Mike is the taller of the two．迈克是这两个中比较高的。
5．“A ＋ be ＋形容词比较级＋ than ＋ any other ＋名词单数＋比较范围”可表达最高级含义。如：
Tom is thinner than any other student in our class．汤姆比我们班里的任何学生都瘦。
注意：
1．修饰比较级的词有：much，even，far，a lot，a little，a bit等。
2．表示“和……一样”时，用“as ＋形容词或副词原形＋ as”句型。否定形式用“not as/so ＋形容词或副词原形 ＋ as”。如：
