[問題] too跟also的差異點??

[monyu (....)]

我想請問大家too跟also除了放在句子裡的位置不同之外,還有其他差異點嗎?

(1) John is a teacher,and Mary is,too.

(2) John is a teacher,and Mary is also a teacher.

(3) John is a teacher,and he is also a doctor.

(4) John is a teacher, and he is a doctor,too.

以上四句皆可成立嗎？？

推 changwenchi:看起來都很ok耶！應該不是說位置的不同，而是詞性本來
→ changwenchi:就不同吧！不知道專家的看法？
