more than與over的關系

over做介詞表“超過”時，可用more than代替。

例：he has stayed here over a year.

= he has stayed here more than a year.

（他已待在此地一年多。）

he has stayed here more than over a year.(x)

he has stayed here much over a year.（×，much應刪除）

over five students are here.

= more than five students are here.

（這裡的學生有五人以上。）
