Have we got any apples?

Let's look in the fridge. No, we haven't, but we have some grapes.

I want to make an apple pie. Shall we make a shopping list?

-That's a great idea.

How many apples do you need?

About a kilo. And some sugar.

-There's a packet in the cupboard.

Yes, but there isn't enough sugar in it. We need more.
