Far too vast and complex a question to answer here, Mr. Duong. Might I suggest that you start with your dictionary, and get back to us with more specific inquiries?

Hi Mr Duong,

You could take a look at some material I've written for the site showing prepostions in use. If you go to esl lessons, you will see the word Prepositions in the index.

You may find it useful.
