4. Miss Wang says that there is no _re_a_s_o_n__ for Lisa to throw away her friendship with the boy.
5. Miss Wang asks Lisa to _ig_n_o_r_e_ her gossiping classmates and show them that she is more _g_ro_w__n_ up.
TEXT
Dear Lisa,
There is nothing wrong with you and this boy being friends and studying together. And no matter what other students say, it is possible for a boy and a girl to be just good friends. Ending your friendship with this boy would be a stupid thing to do. Not only would you lose a good friend, but you would also lose someone who is helping you with your studies.
Teenagers like to gossip, and they often see something that doesn't exist. Perhaps they can't understand your friendship with this boy. But that's no reason to throw it away. You should feel sorry for those students who have never enjoyed such a friendship. My advice is to ignore your gossiping classmates. That way you will show them that you are more grown up than they are.
