Listen to the dialogue 2.

How’s it going at school, Peter?

Not bad.

What’s your favorite subject?

Mr. Lin is my music teacher. He teaches well.

Everyone likes his class.

How about other subjects?

I like Ms. Huang’s math class, too.

But she gives a lot of homework.

Is it difficult?

Yes, but Bill helps me with it every evening.

He is good at math.
