1. a rush order= an urgent order?
2, I'm behind on my presentation.-why not: I'm behind with my presentation.?
3. (to work )then over the weekend = (to work) later during the weekemd?
4. I'll be ready by Monday- why not: I will have been ready by Monday?-is it also possible? and both are acceptable?
or I'll be ready by Monday= I will have finished my work by Monday? ?-is it also possible? and both are acceptable?

Many thanks!

1. yes
2. choices again - both prepositions can be used.
3. "I'll work all day Friday on it, then over the weekend if I need to." I'll work on it on Friday - and also on Saturday and even Sunday if I have to.
4. I will be ready - future tense. 'Will have been' is incorrect, but 'will have finished' is acceptable.

Dear B., why is 'Will have been' incorrect?

thanks

[Beeesneees]

Because it is not yet Monday.

1.I'll be ready by Monday.
2.I will have been ready by Monday.
3. I will have finished my work by Monday.

I know that it is not Monday yet, but by this day work will be finished or somebody will be ready. So, the second sentence would be correct maybe this way:
I will have been ready on Monday??

thanks again

[Beeesneees]

No, no matter how you try to justify it, it is grammatically incorrect and makes no sense.

Ok Dear B., keeping close to your argument: Because it is not yet Monday, I don't still not much understand why 'Will have been' is incorrect. Could you please try to explain it more clearly or on the other side?
Many thanks in advance
