sentence structure: on which, for which, in which


Would anyone advise what kind of grammar book I should refer to for studying the sentence structures like the following?


(1) The assumptions on which the recommendation is based are erroneous.

(2) For each tactic  suggestions are offered about the communication tasks for which it is suitable.

(3) There are several ways in which this book can be used.

Thanks! But in my thinking and speaking circumstances, i cant think without on which or of which because it shows in my head at the end of the sentence, how to put it in place next to which !? Sorry if my question is confusing because my english skill is trainging and getting better !!
