Class 9 Interact With English | Unit 1 Solutions | Since and For

Exercise 9

Since and for

The time expressions since and for indicate the duration of an action.

We use for to say how long something lasts.

  • It has been raining for two hours.
  • The house has been empty for six months.

Since gives the starting point of actions or events. It says when things began.

  • It has been raining since morning.
  • The house has been empty since January.

Note that we often use the present perfect or present perfect continuous tenses with since and for.

  • I have been learning classical dance for six months. (NOT I am learning classical dance for six months.)
  • It has been raining since morning. (NOT It is raining since morning.)
