all this work ?

[namsteven]

Dear Teacher,

1) How long have you been dating with her ?

- Is this sentence ok to say ?

1) “ All this work “

- Can we use “ all these works “ instead of using “ all this work “ ?

Thanks a lot.

Best regards.

- Is this sentence ok to say ? (OK as corrected).

1) “ All this work “

- Can we use “ all these works “ instead of using “ all this work “ ?
(Both are correct in the right context.
Example: 1) Look at my desk! I have to finish all this work before Friday!
(All this work is considered as one collection, thus the singular "this work").
2) Thirty paintings hang in this room. All these works will have to be removed before we can paint the walls. (Each work of art is considered separately, thus the plural "these works").
