形容词、副词的比较级和最高级的用法:
当两种物体之间相互比较时,我们要用形容词或副词的比较级;
当相互比较的物体是三个或三个以上时,我们就要用形容词或副词的最高级。

常用的不规则变化的形容词的比较级和最高级:
bad wor worst
far farther (further) farthest(只指距离)(furthest)(用处较广)我的泰州
good better best
little less least
many/much more most
old elder ( older ) eldest(仅指人)(oldest)(指人和物)
形容词前如加 less 和 least 则表示"较不"和"最不"

farther/farthest和further/furthest这些形式都可以指距离。further同样可以指“另外的/更多的”,主要和抽象名词一起用:
Further education will be meaningful.很快会得到更多的供应。
Further discussion would be pointless.继续讨论/辩论是无意义的。
吸豆I am too tired to go farther.
elder,eldest;older,oldest
elder和eldest主要表示的是长幼顺序而非年龄大小。主要用于表示家庭成员之间的长幼关系,如my elder brother(我的兄长/哥哥),her eldest boy/girl(她的长子/长女)。
但在than前不能用elder,只能用older:
He is older than I am.他比我年龄大。

He was as white as a sheet.他面色苍白如纸。
