Today we will learn about 'ago' and 'in'.
'ago'
'ago' always means a time in the past:
Picnic o---------- two weeks -------------o Now
When was the picnic? It was two weeks ago.
New car o---------- three months -------------o Now
Three months ago I bought a new car. (or: I bought a new car three months ago.) - either is ok. =)
We can use 'ago' even if we don't know exactly when something happened:
Long ago people lived in caves.
Years ago I decided to become a chef.
If something happened one week / one month / one year ago we would usually use 'last':
Watched a movie o--------------- one month ------------------o Now
Last month I watched a movie. (or: I watched a movie last month.)
********
'in'
We use 'in' when something hasn't happened yet:
Now o-------------------- two weeks ---------------------o Picnic
When is the picnic? The picnic is in two weeks.
Now o------------------- three months ------------------o New Job
My new job starts in three months.
If something is going to happen in one week / one month / one year we use 'next':
Now o------------- one week -----------------o Going to the library
Next week I'm going to the library. (or: I'm going to the library next week)
'In' has some other uses too, we will learn about those next time =)
