Number is regularly used with count nouns *a large number of mistakes* *any number of times* while amount is mainly used with mass nouns *annual amount of rainfall* *a substantial amount of money*. The use of amount with count nouns has been frequently criticized; it usually occurs when the number of things is thought of as a mass or collection *glad to furnish any amount of black pebbles New Yorker* *a substantial amount of film offers Lily Tomlin* or when money is involved *a substantial amount of loans E. R. Black*
我觉得number之间应该是one is greater than the other,不能用more than
如果说到名词,比如gg提到的member,可以说there are more than 5 members in this club. I have more than five vases in my house等,
还可以说the number of the members in this club is greater than 5. 但是说member is more than 某个数字 好像不太妥当,因为member和数字完全不同,无法比较,可以试图改变说法,改成more than 5 members....
