Will or going to

I...buy a new computer next month.

- We haven't got any flour!

-Really? I...go to the supermarket,then.

- Why have you bought so much flour?

- Because I...make a cake

Look at the grey clouds! It...rain.

A hundred years from now, people... go to the moon on holiday.

... you help me with my homework, please?

- I am hungry.

- I...make you a sandwich.

- Your jeans are dirty.

- I know. I...wash them today.

I am so tired! I think I...go to bed early tonight.

I... buy a swimsuit because I want to go swimming this afternoon.

We are going on a school trip. We...take a packed lunch.

I am not sure, but I think it...snow next week.
