C Present perfect and past perfect

The past perfect acts as the past form of the present perfect (see Units 5-9).

It is often used with adverbs like just, already, never. Compare:

I am nervous because I have never given a presentation.

(I am about to give a presentation.)

I was nervous because I had never given a presentation.

(I gave a presentation yesterday.)

The past perfect is often used in reported speech structures (see Units 30-31) and in 3rd conditionals (see Unit 21).

D Past perfect continuous

The past perfect continuous is formed by using the auxiliary had been+ the -ing form of the verb (I/he/you/etc. had (not) been working).

We use the present perfect continuous to talk about how long an activity has been going on up to the present (see Unit 6). We use the past perfect continuous to talk about the duration of an activity up to a point in the past.

Compare:

I have been working here for six months. (I am still working here now.)

When I left my last job, I had been working there for four years. (I started in 1990 and I left in 1994.)

We do not use the past perfect continuous with stative verbs like know, like, etc. (see Unit 3). Instead, we use the past perfect:

When they met again, they had not seen each other for 15 years.
