How It Helps Your Business English

What this resource offers:

The article opens with the definition of a conditional sentence and a summary of the four types. Each type then has a section of its own: what it is used for, the structure of the if-clause and the result clause, and example sentences. Two further sections cover what falls outside the four, mixed and inverted conditionals, and questions and answers at the end repeat the main distinctions.

How to use this resource:

You read the summary at the top to place the four types, then go straight to the one you need. Each section pairs the structure with sentences you can model, and the examples punctuate the if-clause correctly, which is the part most often written wrong. The sections on mixed and inverted conditionals cover the sentences that follow none of the four patterns, and the questions at the end check what you have taken in.
