人們利用它們來(lái)數(shù)數(shù)，像每個(gè)月的天數(shù)，食物的數(shù)量還有他們所擁有的牲畜的數(shù)目。

amount用作名詞，意為“數(shù)量；總額”，通常用于a(great/large)amountof短語(yǔ)中，表示“大量；許多”，其后通常接不可數(shù)名詞。例如：

Hemadealargeamountofmoney.

他賺了很多錢(qián)。

large)numberof都表示“大量；許多”，其區(qū)別在于前者與不可數(shù)名詞連用，而后者與可數(shù)名詞的復(fù)數(shù)形式連用。例如：1.Alargeamountofmoneywasspentonbooks.

一大筆錢(qián)花在了購(gòu)買(mǎi)圖書(shū)上。2.
