短文改错。 Christine was just a girl in one of my classes.I never knew much about her except for that she was strange.She didn't talk  many.Her hair was black and purple, and she worn black sports shoes and a black sweater, although in the summer.She was, in fact, rather attractively, and she never seemed care what the rest of us thought about her. Like the rest of my classmate, I didn't really want to get closed to her.It was only when we did their chemistry project together that  I begin  to  understand why Christine dressed the way  she  did. _____________________________________________________________
