SOS:the difference between 'work' and 'job'
I already knew that "Work" is uncountable,and "Job" is countable.Now,let's see:
1. We have a lot of work to do this evening.
2. I have already done a lot of jobs since last year.
So,what's the diffrences between the two words here?
Could u explain in English plz?
Thanks so much!
