1. They have been learning English for 5 years.

2. He hasn’t been to a cinema since last year.

3. Mike has known Betty for two years.

4. I haven’t seen you for ages.

5. I have been listening to music since early this morning.

6. It has been snowing for hours.

Почему:

• for используется с периодом времени: for 5 years, for two years, for ages, for hours.

• since используется с точкой начала действия: since last year, since early this morning.

• Present Perfect Continuous подходит для действий, которые начались в прошлом и всё ещё продолжаются: have been learning, have been listening, has been snowing.

• С глаголами состояния, такими как know, обычно используется Present Perfect, а не Continuous: has known.

• В предложениях с be to a cinema и see также естественно употребляется Present Perfect: hasn’t been, haven’t seen.
