英語四六級不會直接考察語法，但是聽力中需要聽句子，閱讀中需要句子，作文中需要寫句子，而語法是句子的骨架，有句子的地方就有語法，所以語法基礎是四六級做題之根本。下面是四級語法辨析：more than與over的關系的資料，希望對你有所幫助！
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.
(這里的學生有五人以上。)
