同学你好~
9. 只修饰可数名词的有:  
many
many a +单数名词
more than one +单数名词
a great/good many
a good/great/large number of
quite a few

只修饰不可数名词的有
much
a great deal of
a large amount of
large amounts of
quite a little


既可修饰可数名词又可以修饰不可数名词的有  
a lot of = lots of
plenty of
a large quantity of
large quantities of
a mass of=masses of
a large sum of （多修饰钱等）

这里students是可数名词复数，所以选择D


10. would rather后接句子时，句子谓语习惯上要用虚拟语气，具体用法为：
1．一般过去时表示现在或将来的愿望
I’d rather you went tomorrow (now). 我宁愿你明天(现在)去。
I’d rather you came next Saturday. 我宁愿你下星期六来。
“Shall I open the window? ” “I’d rather you didn’t. ”“我要不要把窗子打开? ” “我看不要打开好。”
2. 用过去完成时表过去的愿望
I’d rather you hadn’t said it. 我真希望你没有这样说过。
I’d rather you hadn’t done that. 我宁愿你没这样做。

所以这里最好选择B，因为这个人还没有买奶酪，这是对将来的否定虚拟，用动词过去式就可以了。

祝同学学习进步~
