Urgent! How to explain the staggered papers? My girlfriend accidentally handed in the manuscript as homework when she was studying in the United States, and there were many materials extracted from the Internet. At the end of writing an article in the United States, you should write work sited and have references, so that you can quote it. Now I can only tell the teacher that the draft is not copied, and then hand in the real homework. After all, the real homework can't be all online information, right? Or see if by going up one flight of stairs can explain. Try to demonstrate and see if you can do it.
