Прошу помагите с переводом от англ. яз. В рус. Язык..............1)Everyone gets up at 5 am because there's a lot to do on the farm.Sarah's mum is very nice.She brings me a cap of tea in bed,but I just go back to sleep.Later, I go outside to the farmyard to help Sarah's family.Today we are milking the cows in the barn and feeding the chickens. The animals are lovely,but I can't stand the smell. 2)Everyone stays in bed late here.It,s8 am and Annabel's mum is making breakfast! In the afternoon, we're going shopping on Oxford Street and then we,re going to the cinema! I'm so excited! 3)Sarah's mum takes me to school every morining.We drive five miles to meet the school bus,which leaves at 7 am.Sarah's school is very small,but everyone's so friendly. 4)I travel to Annabel's school by tube.Her school is huge with 1,500 students and her friends are very interesting and helpful.I'm enjoying the lessons,but most of all l love the facilities.The computer room and the swimming pool are my favorites. 5)Learning about farming is interesting,but I'm happy I,m going home tomorrow.The fresh air is nice but it's too quiet here.I also feel isolated.In the city,the streets are crowded but you have everything close at hand.I miss the hustle and bustle of London but I don't want to leave all my new friends. 6)Today,I'm felling a bit tired.It's always noisy here and you can hear the traffic all night.I think I,m getting a bit homesick,too.I miss the beautiful landscapes and the people from my hometown.I'm happy I'm going home tomorrow but I,m sure I'll visit London and see Annabel's lovely family again!
