Prime objective of this lecture is to present on Grammatical Use of If. In English we have four ways to make conditional (if) sentences. Here is how to make them: 1st Conditional – is used with ‘will/can + base verb’ for a probable future result. Example: ‘If you study hard, your English will improve.’ 2nd Conditional – uses the ‘simple past’ with ‘modal + base verb’ for imagined, impossible or unreal future situations. Example: ‘If I won the lottery, I would buy a plane.’
