Please may I have your recommendations? I need something which will help me explain grammar issues to a friend who is learning English. I spend a lot of time thinking things through in order to answer her questions, in fact more time than I actually have to devote to it.
She does have her own, but she has several and confuses herself like crazy comparing one to another, and then passes the problem on to me, which then drives me crazy. Then when I come up with an answer, she wants verifiacation from a book.
Help!
