| I'm twelve years old. I'm large 1 my age and have big feet. I look like both my mum and my dad but in 2 ways. I have fair hair and blue eyes 3 my dad, and a mouth and expression like my mum. My nose is like my mother's and definitely nothing like my father's. I am very like my mum in temperament (性情), 4 I don't have her very hot temper (脾气). I hate 5 and arguments. I hate being laughed at and some jokes hurt me more than I 6 . Friendship is important to me with people of all 7 . My home is very important to me and I would hate 8 to a boarding (寄宿) school. On the whole I'm a fairly tidy person. I am quite creative with my hands. I like 9 models, pendants and candles 10 other things. I like acting and music, I 11 the piano and can play the trumpet. I am not very interested in reading because I like to be 12 most of the time. I 13 my bike a lot. My father lives abroad and I enjoy traveling to see him. I enjoy my 14 (We have a French cook) and I have a sweet tooth. I don't like my hair being brushed by someone else and I hate it long. Finally, the one thing I really find 15 is homework as I would rather be outside or make something. | ||||
