Can one say:
1-This tape is helpful for you to practice your English.
2-This tape is useful for you to practice your English.
3-This tape is helpful for you to practice your English with.
4-This tape is useful for you to practice your English with.
I think 1 and 2 are just shortened forms of 3 and 4. But I am not sure that any of these sentence work, especially the ones with "helpful".
They are supposed to mean: This tape can help you practice your English.
Gratefully,
Navi.
