Today I started edit my first draft. I found the topic this time can be little easier than last time. But it still need compare similarities and differences. The last essay confused me because both are war, but this time it's comparison and contrast between nature and human. That could be more clear and intelligible. Therefore, I hope I can do much better this time.
As for grammar study, I think the boundary between run-on sentence and sentence fragments is fuzzy. These two things seem alike. Run-on sentence is not a complete sentence, so do fragments.
