определить complex object и subject если есть

I can tell you smth about making electricity
Going along the street I met my old friends
Being well-prepared she answered readily
I remember attending his lectures on history of Ukraine
Having been shown the wrong direction he lost his way
He saw a group of students talking and laughing loudly
He was proud of having been elected the president of the company
Producing various kinds of complex machinery the workers improved the technological process
The decisions adopted at the plant meeting are supported by the majority of the workers
Standing at the window I watched the people passing by
