Actual does not mean current or present. It means 'real' or 'exact', and is often used in contrast with something that is not seen as real or exact. * actual 与 current 或 present 意义不同，其含义为真实的或确实的，常与不真实或不确实的事物形成对比：◆I need the actual figures, not an estimate.我需要确切的数字，而不是估计。
Present means 'existing or happening now'. * present 意为现存、现行：◆How long have you been in your present job?你干现在这工作多长时间了？
Current also means 'existing or happening now', but can suggest that the situation is temporary. * current 也指现存、现行，但含暂时之义：◆The factory cannot continue its current level of production.这家工厂不能维持目前的生产水平。
Actually does not mean 'at the present time'. Use currently, at present or at the moment instead. * actually 无现在、目前之义，表示此义用 currently、at present 或 at the moment。
