If clause I. Look at the following sentence from the lesson.
If you look at the trunk of a cut down tree carefully, you will find the rings.
The condition introduced by ‘if’ in this sentence expresses a real possibility
whose result/effect is felt in the second part of the above sentence. Note the following points about ‘if clauses’.
1. An ‘if clause’ is also known as a conditional clause. It expresses a condition or cause whose result/effect is expressed or felt in the second part of the
sentence.
2. If the verb in the ‘if clause’ is in the present tense, the other clause (the main clause) normally uses will + verb.
3. An ‘if clause’ can be placed either at the beginning or at the end of the main clause. If it comes before the main clause, it is followed by a comma. However,
if it follows the main clause, there will be no comma preceding the conditional
clause.
