Tom and Mary used to be primary school students in the same school. Mary used to hate examinations because examinations were difficult for her. Now Mary is not worried about the exam, and she is not as nervous as she used to be. Mary used to wear school uniform to school, and she didn't want to think about what to wear every day. It was a waste of time. Now the school allows her to wear whatever she likes. Tom is different from Mary, and the examination is simple to him. Tom used to play at school, but now he studies all the time. Tom also has some changes, such as he used to hate P.E. class, but now he likes P.E. class. Time changes things, doesn't it?
