Plagiarism
Plagiarism is a big deal no matter what you're writing, how often you do it, when you do it, or where you do it. Taking someone else's words and saying that they were yours not only is bad to do, but is also kind of rude. How would you like it if you said a joke and someone took it and say they made it up? It is the exact same thing.
In my view yes it is very wrong, like at least say what website you got it from. I will admit that yes i have done this before, but that is also before i knew how wrong it really was. Now i at least list the websites that i use. I just can't believe that you would try to get away with it in college. They check your papers instantly now, especially in the higher colleges. No matter how good you think you are at trying to rearrange the words they will still pick it out.
This picture explains it all. When you plagiarize do you really feel good about yourself? No you feel good about yourself when you complete a paper that you wrote. All you get is that since of hope that your teacher doesn't find out that you did just copy and paste this. So just think before you copy that, is it really worth a 0? No nothing is worth that.
