Interviewer: Dr. Pitman, how did you become __11__ expert on smell?
Dr. Pitman: Well, I didn't intend to in the first place. __12__ I was in university, there was a course on senses. The other senses seem to be more concrete (固定) somehow. But smell is so personal, I found it extremely interesting.
Interviewer: Do you have any interesting information __13__ (give) us about smells?
Dr. Pitman: Well, let's see. Do you know that it is __14__ (hard) to forget smells than to forget facts? There has been an experiment __15__ people could pick up a particular smell 30 days after __16__ (smell) it for the first time.
Interviewer: Really? So smells can bring back more memories than music?
Dr. Pitman: That seems __17__ (be) the case.
Interviewer: That's interesting. So, what's your favourite smell?
Dr. Pitman: Oh, I have lots of different ones. The smell of the sea reminds me __18__ happy family holidays; and the smell of roses __19__ (make) me think of my friend's house. Strangely enough, I like the smell of aircraft fuel on airports and then I know I am going to fly somewhere __20__ (excite). But the general smell of garden in the rain I really like the most. That means I'm at home where I should be.
