Present Simple Negative in songs // What a Wonderful World

In order to practise the present simple - negative, 1 ESO A students are going to learn and sing this version of Sam Cook’s "What a Wonderful World":

I don’t know much about History.

I don’t know much Biology.

I don’t know much about a Science book.

I don’t know much about the French I took.

But I do know that I love you

and I know that if you love me too,

what a wonderful world this could be!

He doesn’t know about Geography.

He doesn’t know Trigonometry.

He doesn’t know about Algebra.

He doesn’t know what a rule is for.

But I know one and one is two

and if this one could be with you,

what a wonderful world this could be.
