Dear debbie
our new house is just great.I moved into a new house last week and ı couldn't wait to tell you about it.The house is in one of the most beatiful places you can imagine.My parents call it 'our little paradise'. It's a bungalow with a front and back garden.From the front we have a view of the sea and behind the house there is a forest.It is much nicer than the blocks of flats in town and my bedroom is much bigger than my old one.I hope you can come and visit me one day.Write back soon and tell me about your house

Dear jasmine,
I'm glad to hear that you like your new home.It sounds much better than your old flat.As for me,I live in townhouse in the city.Our house is larger than most townhouses;in fact we have three storeys.From our house you can see skyscrapers so the view is not as beatiful as it is from your house.I'm also pretty sure that it is noisier than where you live.We are very lucky though,because my parents also own a small cottage near the sea where we go on holiday.I think it would be a great idea for you to come with us next time.What do you think?

1 Why do Jasmine's parents call the house our little paradise? 2 What type of house is it? 3 What is there behind her house? 4 What type of house does Debbie live in? S What is the view from Debbie's house? 6 Where does Debbie stay when she's on holiday?
