My Favorite Subject
Everyone has his own favorite subject, so do I My favorite subject is English. I like listening to English songs and dancing to them. I am interested in speaking English. All of my classmates and teachers always say my English is the best in our class. And I am happy to hear that. I think English is very important because it is spoken by people all over the world .and it is useful for me when I have a job in the future. So I must work harder than before.
