1. We only use past simple ("faced") when we know the specific time when something occurred ("last year" or "when I was 10 years old"). Since you haven't given us that information, you should use present perfect. "Big trouble"is OK but very colloquial. 2. The "correct" version is also wrong. You should have said "...is never easy". We never say "not ever"; instead, we always say "never"or a contraction like "doesn't ever". 3. The original is OK, and the "correct" version is wrong. Personally, I would say "had *the* opportunity". I'd also erase the comma: "...back then had the opportunity to...". "had an opportunity to"=47,400,000 google hits "had opportunity to"= 425,000 google hits "had the opportunity to"=214,000,000 google hits So, my version is 5 times more common than the original version, and the original version is 1,000 times more common than the "correct" version. 4. Yes, it can mean "in front of", but that meaning is archaic and formal. These days, "before"is much more likely to mean "earlier than". Your original sentence looks like it means "he has never talked earlier than 5 other people." 5. replace "hand" with "hands", and replace "be so" with "become very". I'd also recommend replacing "not" with "never", although "not" is OK. Good questions!

1- Challenge here mean competition between two things so you finally won or defeat but trouble mean bad things without answers this expression to how much abbility you have to defeat ur problems 2 - we can said not easy :D :D 3- opportunity is adjective don't take punctuation . 4- let's guess with me the meaning of this ... ( He has never talked before ) .. before what ??? ( more than 5 people )i don't understand the meaning not complete sentences like we said (he usually speaking with others) .. so what can i do every one speak with others but if i said he usually speak politely with others so i confirm the meaning .
