- He had served in the Army for ten years; then he retired and married. His children were now at school.
As I know the past perfect is used for actions which happened before another action or time in the past. So according to my knowledge the above sentence means something like below.
The grammar book which I copied this sentence says,
"If we put the last verb in this sentence into the present tense, the other tenses will changed to the simple past."
2. He served in the Army for ten years; then he retired and married. His children are now at school.
Questions:
- If my diagram forms are correct, In the first sentence , why has simple past tense been used in the phrase 'he retired and married'? Shouldn't it also be in past perfect since it had happened before another action which describes children's school period?
- In second sentence; When the last verb was put in present tense, why do the other tenses change into the simple past?
- Is it wrong if we use the past perfect for second sentence?
