Question

reglas para colocarle s, es,ies a los verbos utilizando los sujetos she, he it​

Answer 1

En la tercera persona del singular, el verbo siempre termina en -s:
he wants, she needs, he gives, she thinks.
Para las formas negativa e interrogativa, se emplea DOES (= tercera persona del auxiliar 'DO') + el infinitivo del verbo.
He wants ice cream. Does he want strawberry? He does not want vanilla.
VERBOS QUE TERMINAN en -y : en la tercera persona del singular, se cambia la -y por -ies:
fly --> flies, cry --> cries
Excepción: cuando una vocal precede a la -y:
play --> plays, pray --> prays
Añadimos -es a los verbos que terminan en:-ss, -x, -sh, -ch:
he passes, she catches, he fixes, it pushes
