Explicação:
No Simple Present, quando o verbo estiver em I, You, We ou They, apenas retiramos a partícula "To", mas quando estiver em He, She ou It (3° pessoa do singular) teremos que conjugar assim:
Quando o verbo terminar em o, z, ss, ch, sh ou x, devemos acrescentar "es" no final do verbo;
Quando o verbo terminar em consoante + y, devemos retirar o -y e adicionar "ies";
Quando o verbo terminar em vogal + y, devemos apenas adicionar um "s";
