数量的比较
我们常用“more … than”和“fewer/less … than”对人或事物的数量进行比较，表示“比……多”和“比……少”。如：
He has more books than me. 他的书比我多。
Tom in in fewer clubs than Jack. 汤姆参加的俱乐部比杰克少。
We drink less coffee than tea. 我们喝咖啡不如喝茶多。
注意：表示“比……多”时，无论可数或不可数名词都用more修饰；而表示“比……少”时，可数名词用fewer修饰，不可数名词用less修饰。
我们常用“the most”和“the fewest/least”对人或事物的数量进行比较，表示“最多”和“最少”。如：
Simon drinks the most. 西蒙喝的牛奶最多。
She can sing the fewest songs in out class. 我们班里她会唱的歌最少。
He finishes the least homework of us three. 我们三个人里，他完成的家庭作业做少。
注意：表示“最多”时，无论可数或不可数名词都用most修饰；而表示“最少”时，可数名词用fewest修饰，不可数名词用least修饰。
副词的比较级和最高级
有时我们对事物进行比较，还会用副词的比较级和最高级。如：
Daniel drives faster than me.
丹尼尔开车比我快。
She plays volleyball (the) best in her class.
她在她的班级中排球打得最好。
注意：副词最高级前的the有时可以省略。
副词比较级和最高级的构成方法与形容词基本相同：
规则 原级 比较级 最高级
单音节词 大多数词后加er或est low fast lower faster lowest
fastest
多音节词和部分双音节词 在词的前面加more或者most beautifully quickly more beautifully more quickly most beautifully
most quickly
其中常见的不规则变化有：
well—better—best、
badly—worse—worst、
far—further/farther—furthest/farthest
有些词即可做形容词又可作副词，如：far、fast、hard、high、late、long和well。
