Dear Jimmy,

How are you? I’m sorry I haven’t been in touch lately, but I have been studying hard for my exams. Well, let me tell you my news!

To start with, I have had a really nice haircut and I look so different now! I have also signed up for a taekwondo class! We haven’t started yet, but we’ll start in a week. My friend, Billy, has been taking the same class for two weeks now. I think you have met him before. He was at the college concert last week. Billy says that it’s great exercise and a lot of fun. He hasn’t had many lessons yet, but he has already learned some basic moves.

Well, that’s my news! Let me know what you have been doing with yourself lately. Is it true that you’re moving to the country? Have you found a house yet?

Как выбрать время:

• Present Perfect: have/has + V3 — важен результат или опыт:
  have had, have signed up, have met, has already learned.
• Present Perfect Continuous: have/has been + V-ing — действие длится или происходило в последнее время:
  have been studying, has been taking, have been doing.
• Слова yet, already, before часто указывают на Present Perfect.
• for two weeks now показывает длительность, поэтому используется Present Perfect Continuous.
