Объяснение:
present perfect ты используешь, когда • действие завершилось недавно (напр: she has tidied her room)
• действие, которое завершилось в неустановленное время и оно связано с настоящим (напр: He has lost his keys. (He is still looking for them))
• когда у действия есть акцент на число или дата(например: she has spoken to two clients since 12 o'clock)
•какие-то изменения, происходившие в течение времени (например: she has lost weight)
present perfect continuous ты используешь, когда:
•действие началось в и до сих пор продолжается (напр: he has been writing a letter for two hours. (he started two hours ago and he is still writing))
• действие в котрое имеет результат (например: she has been crying. Her eyes are red.)
• действия выражают эмоции по типу злость, раздражительность, критика (например: who has been using my hairbrush? (annoyance))
• есть акцент на продолжительность (обычно используется for, since или how long)
не коротко конечно, но я пыталась )
Dear Julia,
Thank you for your letter. Sorry that I haven’t written to you for a long time but I have been busy.
When I have my spare time I go to the sport club, go for a walk and, of course, sleep. To tell you the truth, all members of my family prefer different kinds of activities, for example, my mom prefers cooking, my grandfather likes sitting with my sister. So, I prefer listening to music, and, as you know, going to parties!
Wow! Your birthday! It’s cool! Who was invited to your party? What presents did you get? And what about the best present?
Sorry, but I must go now. Hope to hear from you soon.
Best wishes,
Vova
