than后面怎么跟 跟主格还是宾格

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。
