LI RU: I think someone who is happy to persevere at something and learns from his mistakes.MIKE: Thank you. I think designing robots sounds fun.


Robert Briggs is very interested in biology and especially in the study of plants. Today he is telling his friend Zhang Wei some exciting news. Before you listen to the tape discuss with your partner how you would find out the name of a flower. Listening (P41)
