Restating

A form of the conditional is used when information has been already mentioned.
Many times the form of the conditional is not complete. For example:

• New dress? Come and get the shoes to match.

The complete conditional sentence can be restated as:
If you have a new dress, you can get the shoes to match.
Sometime the truncated forms of the conditional, If so, if not, are used. For example:

• Many of you are already familiar with this information. If so, this section is just a practice.
• Did you call Juan for his birthday ? If not, you are still on time to do it.

Contrasting

Sometimes the if clause expresses an opposite or a contrast of something said previously. Many times the if clause is not present and it can be a little hard to identify the sentence as a conditional. For example:

• I like eating fish, but if it is not cooked well I can't stand its taste.

Listing Alternatives

A conditional can be used to present alternatives. One main clause can have several if clauses. For example:

• Welcome to Bank Iowa's phone system. If you want to check your balance, press 1. If you want to know what checks have been paid, press 2. If you want to exit, press 3.

A conditional can be used to give examples that support a previous statement. Introductory expressions such as, for example, for instance ,can be used. For example:

• You need to take precautions in this city. (For instance) If you are walking at night, don't wear jewelry. If you don't see anyone on the streets, take a taxi.
