Extra resources to study linguistics

I have a difficult time understanding how to breakdown sentences (English). I'm not the worst student though (90.66% lmao) but I'm always super confused on how to break down sentences into active/passive, ties, shifters, something called x-words and more. We've just gone over Wh questions and traces and I was just so lost. Do any of you guys have any tips on how to study linguistics? Sites and such are welcome.

A list of resources in my course given to me: Video lectures/lessons Practice problems You can view questions in quizzes Our textbook is Steven Pinker's "The Language Instinct (2007)" Extra overview on examples of linguistics in effect

P.S. I am unable to get help from professor due to the current time crunch I'm having.

Thanks for any response in advance.
