Luyện nghe bài hát The Professor's Song

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

My diagrams are of true art, you must agree,
And my is famous for it's legibility.
Take a word like "minimum" (to a random word),
This was performed at a blackboard, and the professor

For anyone to say he read that, is absurd.
The anecdotes I tell get more every year,
Though frankly, what they go to prove is sometimes less clear,
And all my explanations are lucid, I am sure,
Yet everybody tells me my lectures are obscure,
And I think why.

Consider, for example, just the force of
inversely proportional to something - let me see -
It's r^3 - no, r^2 - no, it's r, I'll bet -
The sign in front is - or is it minus, I forget -
Well, anyway, is a force, of that there is no doubt.
All these formulas are trivial if you only think out.
Yet students tell me, "i memorized the whole year through
Ev'rything you've us, but the problems I can't do."
And I think why!
