Trang 1"Before" và "Ago"
Đôi khi các học viên vẫn dùng nhầm lẫn giữa 2 từ "before"
và "ago" Trên thực tế việc phân biệt chúng không khó Các bạn hãy xem những giải thích dưới đây nhé:
She is the young girl that he met many years ago when
he was in a prisoner of war hospital
The word that jars is ago where the time clause is past
Trang 2tense
before - at some unknown time before now
ago - at a certain time before, counting back from the
present
Another way of writing the above sentence with before
would be to make use of a past perfect tense:
She is the young girl that he had met many years before when he was in a prisoner of war hospital
Trang 3Even if the lapse of time had been specified, the sentence would still call for before:
She is the young girl that he met twenty years before, when he was in a prisoner of war hospital
Ago is for counting back from the present Therefore,
when time is specified, ago is in use
For variation, you can use earlier or previously to indicate
a time before a time already in the past
