问题描述：
Digging a well is hard work.hard work前为何不加冠词?A diamond is very hard.diamond前为何加a?
答
hard work不可数，
而diamond是可数名词，所以前面会加a
答
work是不可数名词。diamond可数名词。
比如news也是不可数:
it is good news for me.
答
hard work不可数,不可数名词前要么加the,要么什么都不加,加不加取决于整句话的意思.拿A diamond is very hard来说吧,diamond前加a,整句的意思就是泛指钻石这种东西很贵.如果加the,这句的意思就成了特指某颗钻石很贵....
答
I think it should be: "Digging a well is a hard work."
A diamond is very hard. Here "a diamond" means any piece of diamond.
