Sometimes if is omitted.

• Were I you, I wouldn't refuse this offer. (= If I were you I would not refuse this offer.)

Expressing a condition using unless

We can express a condition using unless.

• Unless you give me the keys of the safe, you will be shot.
• Unless you agree to my proposal, you cannot expect any help from me.

A condition can be expressed using a conjunctional phrase like in case or but that.

• In case it rains, I shall put on my rain coat.

It is also possible to express a condition using a participial phrase.

• Supposing he does not come, what will you do?
• I will help you provided that you follow my instructions.
