[Exercise 4]

`1.`

- They last saw each other 6 months ago.

- It's 6 months since they (last) saw each other.

- The last time they met each other was 6 months ago.

`->` S + have/has + not + PII + for + khoảng thời gian / since + mốc thời gian

`=` S + (last) + V2/ed + time trong QK

`=` It + be + khoảng thời gian + since + S + (last) + V2/ed

`=` The last time + S + V2/ed + was + time trong QK
