Past Perfect Tense

We use the past perfect tense for an action that took place before a certain time or an action in the past.

For example,

• The train had already left by the time I reached the station.
• The teacher had not yet begun the lesson when Priya arrived.

When two actions happen in the past, we use the past perfect tense to indicate which action happened first.

For example,

• We had finished our dinner before the guests arrived.
• I had completed the sums when the teacher called me.

Will and shall are both used to show the future tense. Will is also used to make a strong statement about an action in the future.

For example,

• I will do everything possible to help him.
