Quando é she (ela), he (ele) e it (que é usado para objetos, animais e etc) acrescentamos o s no verbo em inglês... 
Se o verbo terminar com a letra -o, -s, -ch, -sh, -x, ou -z acrescente -es: goes, does, misses, watches, washes, fixes, buzzes, etc.
Se o verbo terminar em uma sequência de consoante e -y, tire o -y e acrescente -ies: cry » cries, try » tries, study » studies, reply » replies, etc. (Obs.: se o verbo terminar em uma sequência de vogal e -y, basta acrescentar -s: pray » prays, say » says, play » plays);
(Os verbos be e have são exceções a tudo isso, pois eles terão as formas is e has)
