They're both grammatically correct but they are used in different contexts. correct - Used in a situation where you sent someone the wrong papers originally, so now you are sending him the correct ones. corrected - Used in a situation where you edited someone's paper (corrected it) so now you are sending him the corrected page.

every person who has a profile on Facebook NEEDS to realize policeman instead of policeworker law abiding citizen instead of law obedient person With that in mind, one should be more careful with the things one post on Facebook. (new sentence) If you said to your boss... The last sentence is very long and I'd suggest splitting up the ideas into separate sentences and making it more concise.

Yep, I agree with fdmaxey about the meaning. If you wanted to ask how to improve the sentence, I think this version sounds more natural: The first time, I had to seduce the victim. But this time, he/she fell right in my trap.

I've always thought of 'avenge' as the verb form of revenge.. somewhat similar to effect/affect. By avenging something, you get revenge. In fact they're almost equivalent. Spiderman swore to avenge his uncle's death. = He swore he'd get revenge for his uncle's death. However, I think that one way they differ is that avenge has a more serious tone. Revenge can be used more lightly, such as if you say to a friend "I'm going to get revenge, just watch out!" in response to a prank he pulled, let's say. You could say that as a joke, without really intending to get revenge. Maybe it's because the word has been overused, I don't know... but that's my experience with using the word haha.

They're pretty much interchangeable.
