Explicação:

Note que quando o verbo está na terceira pessoa do singular há uma mudança no  verbo. Na maioria dos verbos adicionamos a letra "s" ao final da palavra, exemplos: dance - dances, write - writes, sing - sings.

Há outros casos como:

• Verbos que terminam com -ss, -sh, -ch, -x e -o  se adiciona ao final do verbo o -es. Exemplos: kiss - kisses, wash - washes, watch - watches.

• Verbos que terminam com consoante + y, retiramos o y e adicionamos o -ies. Exemplos: study - studies, cry - cries, fly - flies.

• Verbos que terminam com vogal + y, adicionamos um -s ao final do verbo. Exemplos: play - plays, say - says, enjoy - enjoys.
