e.g. The weather in Beijing is colder than that in Xi’an. Our school is bigger than yours.
③ the + 比较级
e.g. Lucy is the fatter of the two girls.
④ “a/an + 比较级” 表示“又一，再一”
e.g. Lily has a doll, but she wants a bigger one.
⑤ 隐性比较（没有than的情况）
e.g. Who runs faster, Lucy or Lily You’d better come earlier next time. He worked hard last term, but he works even harder this term.

比较级 + and + 比较级
b. the + 比较级 + 句子，the + 比较级 + 句子

e.g. Beijing is one of the biggest cities in the world.

e.g. Tom is the tallest student in the class.
= Tom is taller than any other student in the class.
= Tom is taller than all the other students in the class.
= No other students are taller than Tom.
总结：
① any other + 名词单数
the other + 名词复数
② 否定 + 比较级 = 最高级
比较级 + 极限 = 最高级
同级比较
① as + adj./adv. + as
e.g. She is as thin as Lily.
He writes as carefully as Linda.
② not + as/so + adj./adv. + as
