1) I put my feet on the pedals
2) I put on my feet the pedals.
The first sentence is from an ESL textbook for Korean middle schoolers and the book says the second sentence is not correct. I know 2) sentence sounds odd, but I can't explain to my students why 2) is wrong -grammatically.
And... what about this?
3) I put on my feet.
4) I put my feet on.
Are both 3) and 4) grammatically correct and make sense?
