1. I’m trying to study. I have been trying to study for the last hour, but something always seems to interrupt me. I think I’d better go to the library.
2. The children are playing basketball right now. They have been playing for almost two hours. They must be getting tired.
3. The telephone has rung four times in the last hour, and each time it has been for my roommate.
4. The telephone has been ringing for almost a minute. Why doesn’t someone answer it?
5. It has been raining all day. I wonder when it will stop.
6. We have had three accidents so far this week. I wonder how many more we will have if you keep using the tools carelessly.
7. We have been living here since last June.
8. My little son is dirty from head to foot because he has been playing in the mud.
I am on holidays now. Summer holidays is the best time of the year! I can do everything: rest a lot, wake up late in the morning (or even in the afternoon!), go to bed late at night. And the most pleasant thing that I mustn*t go to school! The first month of the holidays is June. I decided to spend it at home. So every day I meet my friends and we go somewhere together. There are a lot of new good films and funny cartoons in the cinema. We have seen 5 new pictures already! We go for a walk several times a day/ It is great! When the weather is fine we go to our aquapark. We like it very much and usually spend the whole day there. Sometimes I read books from the list of recommended literature on summer holidays. But most of them are dull and not so interesting.
