如“He is taller than his brother.”（他比他哥哥高。）
“She runs faster than me.”（她跑得比我快。）
2) 修饰比较级的词：可以用“much”“a lot”“even”“far”“a little”“a bit”
如“This book is much more interesting than that one.”（这本书比那本书有趣得多。）
“It's a little colder today than yesterday.”（今天比昨天稍微冷一点。）
3)“the + 比较级...，the + 比较级...”结构：表示“越……，越……”。例如“The more you practice, the better you will be.”（你练习得越多，就会做得越好。）
4) “more and more + 原级”或“less and less + 原级”结构：表示“越来越……”或“越来越不……”。
如“The city is becoming more and more beautiful.”（这座城市变得越来越美丽。）
2.最高级的用法
1) 三者或以上比较：用于在三个或三个以上的人或事物中进行比较，表明某个人或事物在某方面的程度最高。最高级前一般要加定冠词“the”，后面常跟“of”或“in”短语表示比较范围。
如“He is the tallest in his class.”（他是他班上最高的。）
“This is the most beautiful flower of all.”（这是所有花中最漂亮的。）
2) 副词最高级：副词最高级前的“the”可以省略。
如“He runs (the) fastest in our school.”（他在我们学校跑得最快。）
3)最高级的修饰语：可以用“by far”“almost”“nearly”等词修饰最高级。
