I haven't been able to read your hubs as they are under revision, but the remaining hub does sound almost as if it is spun content. From what you have written I think it would be accurate to say English probably isn't your first language. The way the article is written it could be mistaken for spun content and the grammar could do with some improvement. (Not saying my grammar is perfect either)
In order to find out why your other hubs are currently under revision you'll have to ask the hub team. Try emailing them at email@example.com and they will let you know the reasons.
Be careful, because repeat offenses can result in your account being closed and being banned permanently from Hubpages.
Best of luck!
