The use of perfect past and past continuous

Past perfect
The past perfect is formed by combining the auxiliary verb "had" with the past participle.
We use the Past Perfect tense to emphasize that an action in the past finished before another action in the past started.
subject + "had" + past participle

Past Participle
I, You, He, She, It, We, They
studied, visited, worked...

I had [I'd] visited my mother
They had [They'd] studied English before they went to USA.
I had written the letter before you came home.
She had studied very much before the exam
You had studied English before you moved to New York.
I had finished my homework before I went playing football.
Negative sentences

He hadn’t studied English before the test
I had not bought a new dress.
You had not cleaned the house.
Had you cleaned the house?
Had he brought the gifts?
Had she lost the credit card?
Past continuous
We usually use the Past Continuous to talk about activities that lasted for some time in the past. The actions can be interrupted by something or can be happening at the same time.
Use the Past Continuous to talk about actions or situations that lasted for some time in the past, and whose duration time is unknown or unimportant.
The Past Continuous is often used when one action in progress is interruped by another action in the past. The Past simple is used in such sentences. We usually use when or while to link these two sentences.
was/were + (-ing) + Complement
