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?
湯姆和瑪麗過去是同一所學校的國小同學。瑪麗過去討厭考試，因為考試對她來說是困難的。現在瑪麗不擔心考試了，而且面對考試不像過去那樣緊張。瑪麗過去總是穿校服去上學，而且她也不想考慮每天要穿什麼，這很浪費時間。現在學校允許她可以穿任何她喜歡的衣服。湯姆與瑪麗不同，考試對他來說是簡單的。湯姆過去放學時總在玩，但是現在他用所有時間學習。湯姆也有一些變化，比如他過去很討厭上體育課，但是現在他喜歡上體育課。時間會改變一些事，不是嗎？
