Understanding an explanation

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.



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?

My last lecture at the university was over 15 years ago so it's quite difficult to remember what it was about )) Honestly, it's not difficult - it's impossible. But I think it was something special, you know. After those five long years with so many lectures, so many subjects to learn, so many exams to pass, and you finally got the very last lecture. I think we were happy and sad at the same time. Happy because no more lectures and sad because that was the end of our funny and careless students life.

I am a professor at the university. I hope my lectures are interesting and my explanations are clear. Maybe I am right. But I had to remove my few last lectures to next year due to coronavirus pandemic.

The last lecture that I went was on-line course about clinical Pharmacotherapy 2 months ago. The professor explained It cleverly and I enjoyed It so much.

Sorry, I can't even remember when it was the last lecture I went to. That took place long ago, too long that I started to miss classes, I'd really like to sign up for some presential course to refresh memory and impove my skills. Also, classes are a good way to communicate with people and make new relationships.

I didn't have any lectures recently, but it was last year that we had a nice conference and a person who works for Afghan Electoral Commission, explained us some important points about the importance of justice and equity in electoral process. He also precisely demonstrated the ways of cheating in the process of election. Some examples and statistics were from USA and many other countries. I learned a lot in that day. Best wishes, Tayyebi
Respected Sharif, oh your poor land...wishin' ya good studies and continuing ya studies in Mumbai/more excellent place! :))
