My name is Lana. I’m 13 years old and I study at the 7th form of a secondary school. I am an ordinary school girl who tries to look up-to-date. I’d like to tell you a few words about my appearance. I’m quite tall for my age. I’m the second tallest girl in the class. People say I’m slim and good-looking.

To look good I wear a uniform at school and a T-shirt with jeans when I go for a walk with friends. I try not to wear short skirts or dresses because they don’t fit me. In terms of appearance, I take after my mother. I’m quite happy about that, because she is a beautiful woman and she looks rather young in her mid-thirties.

I’ve got long dark hair and big brown eyes. As for my hair, I like wearing it in ponytails or pigtails. I like wearing jewellery or bijouterie but my teacher gets angry, so I simply wear small earrings. My features are ordinary too. I have a round face, straight nose, red lips and thick eyebrows. I don’t use any make-up because I think I’m too young for it. However, when we have parties or balls my mum lets me use some of her cosmetics and perfumes.

Also, I like changing my hair-do for parties. When I spend too much time in front of the mirror my younger brother starts making fun of me. He says all girls are the same. My brother and I are rather different both by appearance and character. He takes after my father, who is of medium height. He’s got short light hair and small blue eyes. He doesn’t like parties and he doesn’t care about his appearance much.

Write true, false, doesn’t say:

1. Lana is short.

2. Lana has a round face, straight nose, red lips and thick eyebrows.

3. Lana and her brother are different both by appearance and character.
