she   is   the    tallest     of    her    sisters哪里错了?

问题描述:

she   is   the    tallest     of    her    sisters哪里错了?

of----in

she is the tallest in her sisters?

She is the tallest in her three sisters,she is the prettiest , too. 在第二个she前面加and,或者把she前面的逗号改成句号 第二个she前面

She is the tallest of all the sisters .这个是官方答案

among.
如果是两个, 可能就用taller than. 所以我认为是三个以上.

请看正确答案she   is   the    tallest     in   her    sisters?

She is the tallest in her three sisters.

she is the tallest among her sisters 如果是多姐妹, 用among.
she is the tallest between her and her sister如果是两姐妹, 用between。
