a amounts of,a amount of,a great deal of,a large number of的区别,

没有a amounts of和a amount of
an amount of=amounts of修饰不可数名词
a great deal of修饰不可数名词
a large number of只修饰可数名词

1没有a amounts of,只有amounts of,修饰不可数名词; a (large) amount of 修饰不可数名词;
2 a great deal of 修饰不可数名词;a large number of修饰可数名词。

没有a amounts of 啊!
amounts of+可数名词复数
an amount of+不可数名词
a great deal of+不可数名词
a large number of+可数名词复数

第一、二个是 什么的总数 没有词组又有a又有s复数的 修饰不可数名词
a large number of 修饰可数名词,表示什么的一个很大的数,单复数看前面的number
