Gammar Contents:
 
1) Have to:

We often use have to to say that something is obligatory, for example:

Children have to go to school.

Use of have to

In general, have to expresses impersonal obligation. The subject of have to is obliged or forced to act by a separate, external power (for example, the Law or school rules).Have to is objective. Look at these examples:

  • In France, you have to drive on the right.
  • In England, most schoolchildren have to wear a uniform.
  • John has to wear a tie at work.

In each of the above cases, the obligation is not the subject's opinion or idea. The obligation comes from outside.
