J:So,Sue,you have science this semester?
S:Of course,I think I have just imformed you that.What major are you taking currently?

J:That is right!Professor Thomas,it is a surprise to me that you are interested in this program as well.Do you mind me to give an interview about your opinion on the relationship between environment and wild animals?
S:Right now?I don't think Professor is available!I have booked an appointment with him two weeks ago.Your interview will probably take the whole period of my appointment!

J:Thank you Mr.Thomas.I really appreciate you cooperation on our project.Will you be available this Friday morning?
