都可以.
形容词或副词的比较级常与than连用.那么than后的人称代词用主格还是宾格呢?
一、当句中动词为不及物动词或动词的宾语是物时,than后的人称代词既可以用主格,也可以用宾格,意思不变.例如:
Tom runs much faster than I ／me.汤姆比我跑得快得多.
She speaks English better than he ／him.她英语说得比他好.
需要注意的是:如果在than后保留动词的话,这时than后要用主格形式,不能用宾格.例如:
Tom runs much faster than I do.（不能用me）
She speaks English better than he does.（不能用him）
二、当句中动词的宾语指人时,than后用主格代词或宾格代词,意思有区别.试比较:
1.She knows me better than he.她比他更了解我.
2.She knows me better than him.她了解我胜过了解他.
第1个完整句是:She knows me better than he knows me.than从句中省略了knows me; 第2个完整句是:She knows me better than she knows him.than从句中省略了she knows.
需要特别注意的是,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 you do.她比你更了解我.
也可理解为:She knows me better than she knows you.她了解我胜过了解你.
