Grade 6 Grammar Lesson 12 Conditional sentences (0)

A sentence that contains a condition is called a conditional sentence. There are two parts in a conditional sentence: the main clause and the if clause.

   if clause                                   main clause

simple present             will/shall/ can/ may + verb

 We may also use unless in place of if (unless = if…not).

 Sometimes, it’s possible to use the simple present tense in both the clauses.
