I. Read the text and say if the sentence is true or false.

Hello, my name is Helen Brown. Only yesterday I was nine and today I’m ten because today is my birthday. And I’m glad that today is Sunday and not Monday or Friday because on Sundays I don’t go to school. But my school friends are coming to my birthday party. It’s 1 o’clock now and my birthday party begins at 2 o’clock. But my friend Kate will come at 3. She and her parents went to see Kate’s grandmother. I already got my present from my parents. It wasn’t a dress like last year or a CD player like the one they gave my brother for his birthday. It’s a bicycle. I like to ride my bicycle. I also like to read. I know that my school friends will give me books with some of my favourite stories. I like books better than videos or music.
