Hi, Philip. I am very glad to get your letter. How are you? How to study?
I was in abroad three 3 times. I visited twice in Egypt and summer 2013 in Turkey. I prefer to spend holidays in abroad, because I really want to see new places, learn the culture of the country and communicates with foreigners. Abroad I especially love to swim the sea, sunbathing, walking on a variety of excursions, but still love to buy all sorts of souvenirs and clothes.
This summer we are going to fly the whole family abroad once again, I hope we meet again. With love, Alsou

Answer 1

How to study - перевод: Как учиться? Чтобы спросить, как у него идет учеба, лучше сказать: How are your studies? или How are your studies going?
I have been abroad three times (Здесь нужно время Present Perfect). I visited Egypt twice (или: I have been to Egypt twice) and was in Turkey last summer.
В следующем предложении - перед abroad никогда не нужен предлог (to spend holidays abroad) и communicate (без -s).
To swim in the sea (всегда с предлогом). Лучше в этом предложении, чтобы везде стоял герундий (глаголы с окончанием -ing). I love swimming in the sea... going (не walking) on.. excursions
Лучше сказать This summer our whole family is going to go abroad once again. I hope we'll (we will - будущее время) meet again.
