• I lost my pen. OR I have lost my pen. (AE)
• He has gone home. (BE)
• He went home. OR He has gone home. (AE)

Other differences include the use of already, just and yet. The British use the present perfect with these adverbs of indefinite time. In American English simple past and present perfect are both possible.

• He has just gone home. (BE)
• He just went home. OR He has just gone home. (AE)
