Luyện nghe bài hát The Professor's Song

To "if you me your attention."
If you give me attention, I will tell you what I am.
I'm a brilliant math'matician - also of a ham.
I tried for numerous degrees, in fact I've one of each;
Of course that me eminently qualified to teach.
I understand the subject thoroughly, it's true,
And I see why it isn't all as obvious to you.
lecture is a masterpiece, meticulously planned,
Yet tells me that I'm hard to understand,
And I can't why.

My diagrams are of true art, you must agree,
And my handwriting is for it's legibility.

For anyone to say he cannot that, is absurd.
The anecdotes I tell get more every year,
Though frankly, what go to prove is sometimes less than clear,

It's r^3 - no, r^2 - no, it's just r, bet -
The in front is plus - or is it minus, I forget -
Well, anyway, there is a force, of that is no doubt.
All these formulas are trivial if you think them out.
Yet students tell me, "i have memorized the year through
Ev'rything told us, but the problems I can't do."
And I think why!
