2. Function
This tense can be used in Type 3 conditional sentences. It refers to the unfulfilled result of the action in the if-clause, and expresses this result as an unfinished or continuous action. Again, there is always an unspoken "but.." phrase:

• If the weather had been better (but it wasn't), I'd have been sitting in the garden when he arrived (but I wasn't and so I didn't see him).
• If she hadn't got a job in London (but she did), she would have been working in Paris (but she wasn't).

Examples:

• If I'd had a ball I would have been playing football.
• If I'd had any money I'd have been drinking with my friends in the pub that night.
• If I had known it was dangerous I wouldn't have been climbing that cliff.
• She wouldn't have been wearing a seat-belt if her father hadn't told her to.
