Answer 1

1.2 .8后跟不可数 3.4 后跟可数 5.9后跟单数名词 6后的谓语动词是are 7后的谓语动词是is
a number of表示“许多”，相当于 many，修饰可数名词复数。作主语时，谓语动词用复数。number前可用large，small等修饰，以表示程度。

a amount of 是修饰不可数名词的，
a amount of ＋不可数名词，谓语动词一般用单数；
amounts of ＋ 不可数名词，作主语时，谓语动词要用复数。
a good many 只修饰可数名词 a good many of 的话后面要加the
a great deal of修饰不可数名词
a quantity of 后面用is 或does
quantities of后面用are 或do
