As a college student, it is easy to involve in plagiarism. In this developed generation, we have plenty of methods and sources to get enormous informations. For example, numerous researches, papers, opinions, and etc... are overflowing in internet websites, and we can easily borrow some books from libraries. These kind of educational environment easilly lead students to get involing in plagiarism; Furthermore, tough assignment, peer-pressure, lack of knowledge, also effect to it. Haley, Marita, and Jamal, they all have their own academic difficulty. Haley had given tough assignment ,so she used the internet, Marita had lack of knowlegde of plagiarism; therefore she used encyclopedia, and Jamal had some peer-pressure; so he copied some words from old magazine. All of them were punished by their institution, but the level of punishment was vary. It sounds unfair to me, because they are all plagiarized, whether they did intensionally or not, the important fact is that they all misbehaved; therefore, they should be punished equally. People can not distinguish perfectly whether people plagiarize intentionally or not, if someone insist reasonably.
