You forgot to check the grammar in the following sentences yesterday. Thank you.
1) You referred to question number 4 when answering question number 1. Your paragraph is off the subject (or you wandered off the subject?)
2) Express yourself in your own words next time and do not cheat.
3) As I caught you cheating during the exam, I won't evaluate your paragraph at all. As a matter of fact, there is no attempt at expressing your ideas in a personal way.
4) Hamlet wonders whether he had been a coward (and not has been) when he had the opportunity of killing Claudius but didn't take it.
5) Brutus decides to kill Caesar for the freedom of Rome (can you say "for the salvation of Rome or "to save Rome from Caesar's dictatorship?)
