We don't have ---- time to work every year.A much too B so m

首先时间是不可数名词,排除B、D.下面就是much的区别：
（1）too much意为“太多”,它既可作定语,用来修饰不可数名词,也可以作状语,修饰动词.
例如：I had too much housework to do yesterday . 昨天我有太多的家务活要干.
She talks too much . 她说话太多.
（2）much too意思是“过分,太”,隐含了过分而不恰当之意,much too用作状语,一般修饰形容词或副词,不可用来修饰动词,例如：
The question is much too difficult . 这道题太难了.
You’re walking much too fast . 你走得太快了.
很明显,答案是C
