The present simple

The present simple tells habits and facts: I work in a bank, the sun rises in the east. The verb stays the same, except after he, she and it, where it takes -s: she works.

Verbs ending in -s, -sh, -ch, -x or -o add -es: she watches, he goes. After a consonant, y becomes ies: he studies. Have becomes has.

Questions and negatives use do or does, and then the verb has no -s: does she work?, he doesn't like tea.
