I'm planning to copy the speech for the group report in class.
Are you sure its a good idea to copy the speech for your group report?
That idea is really good, I'm gonna take it.
Copying someone's work is a bad idea. The teacher should be the one giving the lessons and doing that work.
Yeah, I'll be doing that work. I have time to copy it and make it my own.
Except that the teacher will know that you copied their work. When they find out, they will likely give you an F on your assignment. If the assignment is worth it a lot it could drag down your entire grade for the class.
