When we talk about finished events with words that mean 'at some/any time up to now' (like ever, before, never, yet, recently, lately, already), we normally use the present perfect.

# |) x' p" I( `4 Q! b0 ?7 E- a8 ~Some verbs refer to actions that produce a finished result. Examples are cut, build, pack, close. Other verbs do not: for example push, live, speak, hit, carry. The past participles of finished-result verbs, and some of their passive tenses, can have two meanings. They can refer to the action, or they can describe the result (rather like adjectives). Compare:
