hi, mark!  

you wouldn't believe but my dream came true and i am in the camp of sailing

now. this is the most important event in my life.   it's great!  

the nature and the weather are amazing.

i met wonderful and interesting people. every morning we start with sports

activities, running, jumping and a lot of swimming. by noon we go out to the

sea for sailing. this is an exciting sport, but it's very dangerous. 

therefore,

in our camp there are very strict rules and we submit to our instructors. for

any disobedience you can be sent home. but i think it is right. you cannot joke

with the water in the sea. in the evening we have our free time. we play

sports, arrange parties or dancing, communicate with our parents and friends. 

it is a pity that you're not here. i really miss you. 

write, how you're  spending your holidays. 

i'm looking forward to your email.

, марк!  

ты не поверишь, сбылась моя мечта, и я

нахожусь в лагере парусного спорта на мазурах.   это здорово!    

природа и погода замечательная. я познакомился с прекрасными и

интересными людьми.  каждое утро мы

начинаем со спортивных занятий, мы бегаем, прыгаем много купаемся. к полудню мы

выходим в море на парусниках. это захватывающий вид спорта, но опасный.

поэтому в нашем лагере строгие правила и мы подчиняемся нашим

инструкторам. за любое непослушание тебя могут отправить домой. но я считаю,

что это правильно. с водой шутить нельзя. вечером у нас свободное время. мы

играем в спортивные игры, организуем вечеринки и танцы, переписываемся с

родителями и друзьями. жаль, что тебя нет здесь. 

я скучаю. 

пиши, как ты

проводишь каникулы. 

с нетерпением жду

твоего письма.

Dear paul, thank you for your letter! i'm glad to hear that you've passed your driving test! congratulations! i'm sorry i haven't written for such a long time. i've been really busy with my new project. by the way, thank you for your brilliant idea. i really had the best presentation last time. i really appreciated your advice. as for your question, i think all you have to do is just regular exercises. don't be lazy and try to find at least 20-30 minutes for your health every day. there is a rule of 30 minutes a day: if you do something at least 30 minutes a day you will have a result at the end of the week. for example, if you read 50 pages during this time, at the end of the week you'll have total of about 350 pages. if we say that we don't have enough time for it (as we usually do) we have 0 result at the end of the week. besides, they say that it takes 21 days to form a new habit. so all you have to do is to take the bull by the horns and try it for just 3 weeks. unfortunately, i need to come back to my project. i hope my advice was helpful. hope to hear from you soon. take care, victor
