finite i non-finite clauses

Czy ktoś może mi wyjasnic na czym polega finite i non-finite clause? Prosze...mam jutro z tego koło i totalnie nie moge zaczaić o co chodzi:(

A non-finite clause is a clause which is based on an infinitive or a participle and has no tense.

A finite clause is a clause based on a verb group which indicates tense, such as `went', `is waiting', or `will be found', rather than on an infinitive or a participle.
