Question about the question Hello. I've got a question: "Why did he tell me how much money he earns?" Why did we use "earns" in the question? I thought that we have to use past tense in here. If he said "I earn 3$ per hour". It's his usual thing. But we used past simple question, I though we need to use a "default" form of the verb? What if it was "I'm talking to a client" how we would ask? (BTW how would we ask or how we would ask?) "Why did he tell he is talking to client? ”? Thanks.

What's the difference between Past perfect and Past perfect continuous Hello. Could you please tell me the difference between these two tenses. Example: "She had been swimming when they saw her" and "She was sleeping when they saw her". In the second example when they saw here she was in a process of swimming and in the first she had finished swimming when they saw here, I guess, right? If so, why can't we use Past perfect instead past continuous? Why can't we say "She had swum when they saw her"? What is the difference between these two tenses then? The same for "It had been raining when he went out" / "It was raining when he went out". Why not "It had rained when he went out"? Thanks
