2. Dr. Jenkins' paper

Corresponding to session 6.2 of GA DR. JENKINS' PAPER

Jimmy:	-- Hello, Doctor Jenkins!	Carol:	-- Where have you been?
Dr. Jenkins:	-- Hi, Jimmy! How are you today?	Jimmy:	-- I was talking to Dr. Jenkins
Jimmy:	-- Fine, doctor. What are you doing?	Carol:	-- Really? What about?
Dr. Jenkins:	-- I'm observing these plants.	Jimmy:	-- He is writing a new paper about plants.
Jimmy:	-- Have you observed them a long time?	Carol:	-- Oh, I've read his works on plants and animals from the rain forest.
Dr. Jenkins:	-- Yes, I have. You see, I'm writing a paper on the growth of plants.	Jimmy:	-- This time it's something different. He's writing a book on the growth of plants under special conditions.
Jimmy:	-- Have you written a lot about plants?	Carol:	-- I haven't read much about that.
Dr. Jenkins:	-- No, not really. I've only written about the delicate balance between plants and animal life.	Jimmy:	-- Well, I guess this is your chance.
Jimmy:	-- How interesting, doctor! Can you tell me more about it?	Carol:	-- I hope he finishes his paper soon. I'm really interested in that.
Dr. Jenkins:	-- Of course.
