Does the earth go around the sun?

[English Learner]

Dear teachers!

I would like to know why it is correct to ask

DOES THE EARTH GO AROUND THE SUN?

as opposed to

DOES THE EARTH GOES AROUND THE SUN?

Thanks

[Alan]

Hi English Learner,

When you want to make the question or negative form of the simple present and past, you have to use the auxiliary verb do+ the infinitive form of the main verb. In this way you have:

Does the earth GO (infinitive) round the sun?

or

The sun doesn't (does not) GO round the earth.
