# Understanding an explanation

Listen to a professor's explanation to practise and improve your listening skills.

Do the preparation task first. Then listen to the audio and do the exercises.

### Transcript

Professor: OK, before we continue, does anybody have a question? Oh, lots of questions, I see. OK, we'll go one at a time. Yes?

Student: Thank you. You talked about Fibonacci numbers in the lecture. Sorry, I don't understand. Can you explain?

Professor: Of course. What do you want to know?

Student: OK … I hope this isn't a silly question, but what does Fibonacci actually mean?

Professor: No question is ever silly – it's always good to ask. OK, it's the name of a person. Fibonacci was a European mathematician in the Middle Ages.

Student: Ah, OK. Thanks. So, we know he was a person, but what are the Fibonacci numbers? I don't get it.

Professor: The Fibonacci numbers are a sequence of numbers. They go 1, 1, 2, 3, 5, 8 and so on. Do you see the sequence? Do you see how it works?

Student: I'm not sure.

Professor: OK. This is how it works. The first number is 1, then 1 again, then 2. The third number is the first number plus the second number. The fourth number is the second number plus the third number: 1 plus 2 is 3. The fifth number is the third number, 2, plus the fourth number, 3. So the fifth number in a Fibonacci sequence is 5.

Student: Ah! I think I understand now. But what about their importance? You said these were very important.

Professor: Yes, let me explain. This sequence of numbers is important because we see it in many things. Fibonacci numbers are common in geometry, they are common in nature, for example in plants. We see the sequence everywhere.

Student: Could you give us some more examples?

Professor: OK ... well, we don't have time right now but I can bring more examples in for next class, OK?

I didn’t remember what my lecture taught me because I had graduated since 2015. But when I am at university, my favourite major is nutrition, and my lecture also gives the lesson clearly, and I understand what she said.

My last lecture was on Expert systems, and the professor discussed PROLOG programming. Expert systems mean we make a computer expert to solve our daily life issues like an expert. PROLOG is very interesting programming. Anyone can make an Expert system if he knows the concept of PROLOG and theoretical knowledge of Expert systems terms like Knowledge Base, Inference Engine, and Expert Knowledge Codification.

What was the last lecture I went to about?

The last lecture I went to was about Soft skills (I attended it this afternoon). I love the lecturer for the way she taught us and how humble she is.

Did the professor explain it clearly?

Something in the lecture was all Greek to me but she tried to explain them so that everyone in the class can fully grasp it. Ah yes, she is also dedicated.

Something I learnt from this audio?
No question is ever silly, it's always good to ask.

The last lecture that I attend is "Biomechanics." Yes, my professor explained it clearly, and he was funny, so the lecture was fun.

What was the last lecture you went to about? Did the professor explain it clearly? The last lecture I read was about the History of Art. I don't have a professor to explain the lectures because I study online, so I do everything on my own.

The last lecture I attended was an introduction to the subject "Applied Thermodynamics and Heat and Mass Transfer" at university. The professor was very clear and spoke calmly. She tried and persuaded students to ask questions to have a feedback. To capture their attention, she explained some curious event like a plane crash due to a mistake in the conversion of different units of measure. In few words, she is a great teacher!
