例如：Lin Tao runs faster than I（me）．林涛跑得比我快.注意：如果人称代词后面有all时,人称代词一般用宾格形式.例如：She draws better than them all．她比他们画得都好.二、如果主句谓语动词是及物动词,且than后面的名词或代词又与动词连用时,than后面的人称代词只能用主格.例如：He loves the dog more than she does．他比她更爱这条狗.（不用her） 三、如果主句谓语动词是连系动词be,than后面的人称代词用主格或宾格均可,且意义无区别.例如：He is much fatter than she（her）．他比她胖得多.四、如果主句谓语动词的宾语指人,than后面用主格代词或宾格代词,意思有区别,常用的动词有like,love,hate,know等.试比较：1．She knows me better than he．她比他更了解我.2．She knows me better than him．她了解我超过了解他.句1的完整形式是：She knows me better than he knows me．than从句中省略了knows me；句2的完整形式是：She knows me better than she knows him．than从句中省略了she knows.需要注意的是,在遇到主格、宾格相同的you时,句子就不能省略了,否则会产生歧义.例如：She knows me better than you． 此句既可理解为：She knows me better than she knows you．她了解我超过了解你.也可理解为：She knows me better than you do．她比你更了解我.当than后的名词是普通名词时,句子也不可省略,以免产生歧义.例如：She knows me better than my parents． 应说：She knows me better than my parents do．她比我的父母更了解我.或说：She knows me better than she knows my parents．她了解我超过了解我的父母.（来自hellen-xu的博客.） 追问：Amy cooks more successfully than______(she).这该用什么?回答：she或者her都可以.你判断一下这两个会有什么区别?追问：不知道.有什么区别?还有这属于上面你归纳的第几类?回答：属于第一类啊!用she或者her都可以,没有区别.saner 的感言：辛苦了,
