PAST PERFECT CONTINUOUS

The Past Perfect or the past in the past:

My mom suddenly remembered she had left her purse at home.When we are looking back from a point in the past to something earlier in the past we use the past perfect:

When we had done all our shopping we caught the bus home.
Romit wanted to lift the trophy, but he had not trained himself well.
Romit would have lifted the trophy if he had trained himself well. 

Functions of the Past Perfect Continuous

The past perfect continuous corresponds to the present perfect continuous, but with reference to a time earlier than 'before now'. As with the present perfect continuous, we are more interested in the process.

Examples

• Had you been waiting long before the taxi arrived?
• We had been trying to open the door for five minutes when Jane found her key.
• It had been raining hard for several hours and the streets were very wet.
• Her friends had been thinking of calling the police when she walked in.

This form is also used in reported speech. It is the equivalent of the past continuous and the present perfect continuous in direct speech:

• Jane said, "I have been gardening all afternoon." = Jane said she had been gardening all afternoon.
• When the police questioned him, John said, "I was working late in the office that night." = When the police questioned him, John told them he had been working late in the office that night.

Forming the past perfect continuous

The past perfect continuous is composed of two elements - the past perfect of the verb to be (=had been) + the present participle (base+ing).
