i'm understand. Thank you

I had line breaks breaks in that explanation. I don't know why they don't appear in my post.

Work VS job. Work has a wider meaning than job, and can be either a noun or a verb. A job is either the thing you are paid to do or it is a specific task. Examples: I have a job as a photographer. Fixing the roof will be a big job. Work can mean job in those senses. Examples : I work as a photographer. (verb) Fixing the roof will take a lot of work. (noun) The wider sense of work is that it is the effort expended to accomplish something. Job is not used this way. Examples : I work hard to learn English. It takes 10 joules of work to lift that weight 1 meter. Work hard for what you want.

It is one word on the Russian. Работа.
