Hi Danyel, I presume that you started writing two hours ago, and you are currently still writing. For describing an event that began in the past and is still occurring, we use the present perfect continuous tense. To construct this tense, we use "has (singular) / have (plural) " + "been" + "verb (continuous)". I have been writing for two hours. If you would like to focus on an event that occurred some time in the past with the effect still applicable at the present, use present perfect tense "has (singular) / have (plural)" + "verb (past perfect form)" I have written the article for two hours. OR I have done my homework. (You did your homework. Now, you homework is still considered as done.) However, it is grammatically wrong to use "have been written". Hope this helps. Cheers, Lance

The first one, present perfect continuous, is talking about an action that you started in the past, are still doing in the present, and will probably continue into the future. This emphasises that you have been doing the action and that the action is not yet complete. The second sentence is incorrect. It could possible be 'I have written the article'. Which means you finished the article but that it is relevant to the present. Hope that helps, Andrew

One is right and one is wrong. 'I have been written...' isn't correct. You can say 'I have written the article.' or 'I have been writing the the article [for two hours[already]]'. Written or wrote are past tense.
