Apparently you don't know the definition of plagiarism, so I've inserted it here for you:

pla⋅gia⋅rism
  /ˈpleɪdʒəˌrɪzəm, -dʒiəˌrɪz-/
noun
1. the unauthorized use or close imitation of the language and thoughts of another author and the representation of them as one's own original work.
2. something used and represented in this manner.

Gee, sure hope you're not going to be teaching reading or writing next term.
