Learn English – the difference between “I used to” and “I had been” in this sentence

past-perfect

I used to live in the US for a year before I became a teacher.

I had been living in the US for a year before I became a teacher.

Is there any difference between the two?

Best Answer

First sentence

I used to live in the US for a year before I became a teacher.

The expression used to describes a situation that no longer exists, or ceased to exist at some specified time. In this case, it means that the speaker moved to the US, lived there for a year, moved away from the US and then (probably straight afterwards) became a teacher.


Second sentence

I had been living in the US for a year before I became a teacher.

This sentence does not feel quite natural because both the past perfect had been and the conjunction before indicate that something occurred before something else: in addition, for a year specifies a time interval. That sounds like it ought to define quite a complex sequence of events.

It could be made more natural by eliminating one of the before-indicators, like this:

I was living in the US for a year before I became a teacher.

This sentence describes a situation where the speaker moved to the US, lived there for a year and (probably directly after that year) became a teacher.

I had been living in the US for a year when I became a teacher.

This sentence describes a situation where the speaker moved to the US, lived there for a year and directly after that year became a teacher.

Alternatively, you could eliminate the time interval specifier, like this:

I had been living in the US before I became a teacher.

This sentence describes a situation where the speaker moved to the US and stayed there for a while, but left some time before becoming a teacher.
