I'm very well thanks. I hope you're well too.
I’m surprised that your grammar book doesn’t cover this subject. Word order is one of the basic rules in English that should be covered in any grammar book.
I did a couple of searches on the internet using “word order” and “subject, verb, object” and came up with the following site:http://esl.fis.edu/grammar/rules/order.htm
You could also try looking on Wikipedia.
Just in case you’re thinking of buying a new grammar book, I think the following are excellent:
English Grammar in Use by Murphy. I like to use the intermediate and advanced versions to remind myself of a certain point in a succinct format.
Practical English Usage by Michael Swan. I like to use this when I’m looking for a deeper understanding of a grammar point.
