In draft 2, I didn’t change a lot of the information. First of all, I changed the problems in my thesis and add a little bit details in the first and second paragraph. I changed some grammar mistakes and typos, but there’re still some grammar errors in the second draft. Thus, I’m going to work on grammar problems in the 3^rd draft. Then, I’m going to add some specific examples in the 4^th paragraph, which states that video cameras can protect students from accidents. Also, I’m going to add more arguments in the 3^rd paragraph to make it a full draft. Then, about my introduction, I think I need to talk more about the system of video cameras and introduce it more specific. Lastly, for the conclusion, I need to add some expectations of the school when it has video cameras.
