I'm not sure if this sentence is correct. Please help me!
I wish Charles worked as hard as Mary ....
I'd use "did" because of the phrase "Charles worked". Is it correct?
Thanks for your help!
It depends entirely on the meaning: 'does' if you are comparing Charles work-rate with Mary's current work-rate, 'did' if you are comparing it with her past work-rate.
Thank you very much!
