What i really need is reading material based on specific grammatical item.
For example, in case of preposition, a passage, essay etc containing a lots of sentence like " The book is on the table inside the box" in its text.
A book such as Michael Swan's PEU contain few example on a rule and newspaper , novels dont teach specific type of grammar.I have been studying grammar for a long time and i realize i need lots of example on certain topic. Otherwise i am not going to be good at it.
So please help
