神奇的钢笔水读后感:a large number of 和a large amount of的区别?

只能修饰可数名词的：a large/ great/ good number of, a good/ great many, dozens of, scores of, quite a few
只能修饰不可数名词的：a great deal of, a large amount of, quite a little,a large sum of
既可修饰可数也可修饰不可数名词的：plenty of, a lot of, lots of, a large quantity of, a good supply of

a large number of 修饰可数名词复数, singular verb
a large amount of 修饰不可数名词, plural verb
a great deal of 修饰不可数名词, plural verb
a large sum of 修饰不可数名词, plural verb

还有，英语多用 a great deal of ，而不是a large deal of 。
