Hi,
I have just published two grammar ebooks that you may find handy:
Focus on Grammar: Subject-Verb Agreement and
Focus on Grammar: Parallel Constructions. Each ebook features hundreds of examples of correct and incorrect sentences.
These ebooks, in epub format, can be read on mobile devices, so you can check up on grammatical points anytime, anywhere.
Please visit

Thank you.
