1. My friend and I always prepare for our examinations together. I took my English exam the day before yesterday, and got "good" for it. My friend is going to have his exam in two days' time. I hope he'll do well at it, too.
2. I'm going to the seaside on my holiday this year. I always spend my holiday by the sea. When I was away on holiday last year, I swam in the sea and sunbathed for three hours a day. The doctor says I shouldn't stay in the sun after twelve o'clock. As I'm going to stay at the seaside, I'll go to the beach early in the morning, and be back home at eleven.
3. My sister is a teacher, so she usually has two months' holiday in the summer. She's away on holiday now. She usually finishes work at the end of June and leaves Moscow early in July. I haven't had any letters from her yet, but I hope to hear from her soon. She'll be back in Moscow in late August.
