David: My favourite subject is chemistry, because the teacher is really nice and he makes the subject very interesting. I don’t like maths, because it’s really boring and very difficult for me.

James: I like science best because I’m very interested in universe. I have read many books about the solar system, the aircrafts and the astronauts. I wish I could go to the universe and explore there one day.

Sam: Art would be my favourite because we can make lots of art crafts (手工作品). I like making model planes best because my father is a pilot. I want to be a person like him in the future.

Mark: My favourite subject is P.E., because I can play basketball with my friends. It’s really very interesting. I don’t like music practice, not because I don’t like playing the piano, but because we have about 60 students in our class and they often talk loudly. It’s too noisy (吵闹的)!
