PRESENT SIMPLE

Verbs in the present tense add an 's' in the third person singular: I work, you work, he/she/it works. But the 's' has three different pronunciations. Look at these examples:

A: /s/, for example treats

B: /z/, for example heals

C: /z/, for example changes

Find the third person present tense verbs in these sentences and classify them by their pronunciation. Put them in the correct columns in the table on the right.
