对的。不省略的话,应该说成:i am taller than she is .
换成her虽常用,但在语法上不是“正确”用法。
参见此例:
i love you more than him .=> i love you more than i love him .
我爱你胜过爱他。
i love you more than he.=> i love you more than he loves you .
我比他更爱你。
用her会比较好 或者 i am taller than she is 也可以
it's okay
错!对的是这样写的
I am taller than her.
I am taller than she.这句话是对的, 相等于 I am taller than she (is taller). 的意思
不可以用 I am taller than her
应该是I am taller than her.
我比她高,她(she)应该用宾格her
